Future Energy
Accelerating innovation and
building a new energy society.
Hydrogen energy is drawing increased attention as a solution for
global warming and energy shortage problems. NGK SPARK PLUG is
contributing to the new energy society through the development of
SOFC (solid oxide fuel cell) technology, which is a particularly efficient
type of hydrogen-based fuel cell. We are also accelerating
technological innovation in next-generation vehicles, with
safety-boosting hydrogen leak sensors and other devices for fuel cell
vehicles that are already coming to market.
Toward energy, the environment,
next-generation vehicles,
and the medical field.
New challenges have
already begun.
Our willingness to take on challenges in new fields is like an engine that
drives our NITTOKU SHINKA-RON philosophy. We are developing products
in the fields of energy, where hydrogen and other alternative sources are
leading to increased diversification, and next-generation vehicles such as
fuel cell cars. In the environment field, we are developing lead-free
piezoelectric ceramics in anticipation of stricter regulations in countries
throughout the world. Furthermore, we are also working on products in the
medical field to meet the growing needs of an aging Japanese society. No
matter what the arena, we create products using our core ceramics-based
technology. We are also actively cultivating human resources to break new
ground. NGK SPARK PLUG is boldly challenging new business domains by
fully utilizing our accumulated technologies and manpower.
SOFC Power Generation System Unit
Stack
In addition to having the highest power generation efficiency among
all types of fuel cells, SOFCs (solid oxide fuel cells) promise benefits
such as compact size and low costs. NGK SPARK PLUG has
developed an SOFC stack for use in home cogeneration systems.
In additional to home use, we are currently developing SOFC stack
for business and industrial use.

NGK SPARK PLUG has entered the medical field by developing
bone filling materials which utilize the properties of ceramics with
superior biocompatibility. Other developments include artificial
femoral heads and bone paste, as well as oxygen concentrators
for medical use. These oxygen concentrators are intended for
domiciliary oxygen therapy for patients with chronic respiratory
disease and other patients. Moreover, we have offered ultrasonic
wave oscillators used as a surgical knife and as a calculus
destruction. With our unique technology and approach, we will
ceaselessly strive to develop new products which create new
possibilities in the medical treatment.

Diversity
Developing Practical
Lead-free Piezoelectric Ceramics
The combined efforts of a various
workforce will yield further growth.
Piezoelectric ceramics produce electrical charge ( voltage ) when
external force is applied. Applying DC voltage causes the ceramics
to expand or contract in response to the current polarity. Applying
AC voltage causes vibrations to occur through repeated expansion
and contraction. With this ability to convert electrical energy to
mechanical energy and back again, piezoelectric ceramics are used
in a wide range of fields, from home appliances to industrial
equipment.
However, current piezoelectric ceramics contain large quantities of
harmful lead, and there is ongoing need to develop practical,
eco-friendly piezoelectric ceramics that do not contain lead. Our
company is currently working on practical products and devices
that use the lead-free piezoelectric ceramics that we have
developed.
The key to further growth of NGK SPARK PLUG is diversity of human
assets. We strive to create a workplace in which each employee can
assert their individuality and fully exercise their ability regardless of
gender, nationality, age, and whether or not they have a disability. We
believe that such a workplace will make employees happy and bring our
further growth. In particular, we actively provide support for female
workers. Currently, we have established the DIAMOND ( Gender
Equality) Project and are revising our systems to create an environment
which empowers female employees. We are also holding forums and
seminars to raise awareness among employees. These efforts were
evaluated highly and brought us the Award for Excellence as the 2014
Nagoya Women Employment Positive Company. By concentrating the
power of such diverse personnel, we are embarking on the DNA Project
to explore our next business themes. This company-wide project
examines product themes which will serve as a core for new

PHILOSOPHY
Inherited Vision
Founding DNA
NGK SPARK PLUG was founded in 1936. However, our roots can be traced back more
than 130 years to the Morimura Gumi which was established in 1876 by Ichizaemon
Morimura, the forefather of the Morimura Group. Our founding father Ichizaemon
Morimura was an honest and passionate merchant. Determined to reclaim wealth which
had flowed overseas, Ichizaemon embraced the challenge of foreign trade for the
prosperity of Japan. Eventually, the Morimura Gumi began to manufacture ceramics and
the Morimura Group was born, ultimately leading to the founding of numerous prominent
companies including NGK SPARK PLUG.

Uniform products through
participation by all employees
“Suppose that we produce only 1 defective product
per 1,000 products. To the customer who purchases
that 1 product, our defect rate is 100%.”
As our business evolved from tableware to industrial products, we faced even stricter
demands for product uniformity. In order to constantly realize the performance need by
customers and to eliminate discrepancy among products, Magoemon Ezoe expected a high
level of discipline and sense of participation to produce quality products. Employees at all
workplaces devoted themselves to manufacturing which fulfilled such expectations. Even
today, the philosophy of producing quality products with participation by all employees is still
alive at NGK SPARK PLUG.

uses pressure swing adsorption to generate air with high
oxygen concentration. The concentrated oxygen is used
in home oxygen therapy, for patients suffering from
chronic respiratory diseases and other ailments.
New ceramics offer superior strength and biocompatibility,
making them optimal for artificial bones and artificial hip
joints. Bone paste is used in a clay-like state and then
hardens with time to fill in a variety of damaged areas.
Bearings use silicon nitride, thus realizing high rigidity
and reducing heating value caused by centrifugal force
and lessening of the friction coefficient. They are used in
ultra-precise high-speed bearings, thermal-resistant
bearings and semiconductor machinery.
Electro-Static Chuck
Vacuum Chuck

NTK Cermet is a standard insert grade which is suitable
for semi-finish and finish turning of steel, general steel
(carbon/alloy steel), ductile cast iron and others, with
longer tool life and better surface finish. PVD coated
cermet has even better wear resistance.
Miniaturization of the main component WC hard grain
realizes toughness and hardness, as well as outstanding
cutting. Furthermore, PVD coated products offer superior
wear resistance and welding resistance, which can be
used for cutting a wide range of materials including
copper, stainless steel, non-ferrous metals and materials
for which machining is difficult.
Formed using CBN (cubic boron nitride) and a special
ceramic binder, this sintered compact maintains high
hardness at both normal temperatures and high
temperatures. There is also little chemical reaction
with the work material. Accordingly, this sintered
compact is optimal for high-speed finishing of ultrahard materials and normal cast iron.
Throw-Away Drills
Throw-Away Endmills
Milling Cutter / FU-HA MILL
With drill holders that are compatible with a range of
shapes and different kinds of drill tip coatings, these
multi–purpose throw away drills can be used even with
machines that have low horsepower or rigidity, due to
its low cutting force. They have excellent chip control
and provide accurate holes.
Compared to high speed steel endmills, these endmills
offer improved tool life and surface roughness and are
designed for reliable shaping and accuracy. Additional
machining operations - side cutting, diagonal cutting,
and helical cutting - are possible in addition to the
usual D-cut by adding a center blade.
For processing of aluminum parts at machining
centers (HFC, HPC, HSC, SFC, ALWC). Realizes high
efficiency and reduced costs by adding an HPC and
steel body (cutter diameter: φ40-100) to the
conventional HSC and special aluminum body (cutter
diameter: φ80-200 ).
Components for Semiconductor
Production Equipment
Ceramics are used to build components requiring corrosion
resistance, abrasion resistance, heat resistance, rigidity,
and lightness of weight that are superior to metal, or for
use in environments with heat-processing equipment,
corrosive gases, or plasma.
Ceramic Heater
This heater is created by embedding a wire inside
alumina ceramics and uniting the parts through sintering.
Lightweight and possessing outstanding chemical
resistance, the heater warms at a fast speed and realizes
uniform temperature distribution. This technology enables
an environmentally friendly and compact design.
