Product introduction
Technical accumulation of Takeishi Electric originates from the foundation of the company, which started as precise filament coil manufacturing company, mainly for lighting industry. From the very beginning, our innotive way of thinking allowed us innovative and build our original automated machine, and original method of manufacturing. Currrently, we not only supply parts for lighting industry, but also to the field of medical and analytical device market. We will introduce some areas of market that uses our products.
Medical
Due to its superb electrical and heat resistance properties, tungsten filament coils are widely used for X-Ray devices such as CT Scanner and PET. Takeishi also manufactures Pt. coated tungsten filament coils.
Catherter for inspeciton and treatment
In order to control torque and hardness, many different methods are applied to SUS coil inside of catherter. High density materials such as tantarum and tungsten are used as a marker when radiation imaging device is used for inspection and treatment.
X-Ray CT PET
Controlling or shutting down radiation level, collimator made of heavy alloy, and resin tungsten sheets or parts are widely used. As X-Ray source, EB Gun using tungsten filament is very popular.
Takeishi products in this area
Samples of precisely coiled filaments, and mesh wire.
Using wire or flat wire (ribbon wire),we form coils made of tungsten, platinum, Pt. coated tungsten, SUS and other materials. Wire diameter could be as small as several microns.
Titanium threaded Bolt (Inplant)
Machined parts made out of tungsten and heavy alloy for X-Ray related medical devices, material like platinum and titanium are used as parts inserted into human body.

Sensor・Analytical Device
Analyzing composition, structure, characteristics of substance is essential, when manufacturing safe products, as well as monitoring environment surrounding us. Wide variety of analytical devices are available for these purposes. As a means to analyze substance, ultraviolet, visible rays, infrared, as well as electromagnetic wave including X-Ray are used. Our products are used in this area, especially for spectroscopic analysis, electromagnetic analysis (X-Ray analysis), and gaschromatographic analysis.
Spectrographic analysis, Infrared analysis
Analysis by radiation often uses lamps like Xenon lamp and Halogen lamp. We supply lamp electrodes and filaments to lamp manufacturers. Blood analyzer and Hematological testing device are some of most important devices for human life.
Electromagnetic analysis(such as X-ray analysis)
X-Ray analytical devices like EDM and EDS are widely used for analyzing composition, chrystalization, stucture and mass.

EB Gun assembled
Other than supplying X-Ray radiating filament, Takeishi supplies assembled EB Guns as we have long experience in assembling and welding various kinds of materials. We can weld filament to stem, assemble with ceramic base.
Filament Coil
With vast experience and knowlege of lamp filament, Takeishi is one of leading companies in the world, supplying lamp filaments for lamp manufacturers all over the world. We manufacture filaments in countless kinds of shape, and add special treatment according to customers needs.

Nuclear power Radiation
Nothing is more important than controlling radiation in the field of Nuclear Power. High density metals such as tungsten and molybdenum are ideal material for shielding radiation intensity. Copper is widely used as radiation shielding material, however it is highly hazadous material. tungsten is known to have very limited negative impact on environment.
Nuclear power plant・Reserch institute using radiation
In order to shield radiation, and to protect environment, many people started paying attention to tungsten parts are also used for nuclear accelerator for research of better and safer use of nuclear energy
Radiation sheilding clothes and epron
tungsten is one of the densest metals, and it is heavy. When used as radiation sheilding materials , clothes and epron for example, resin mixed tungsten is used.
Takeishi products in this area
Resin mixed tungsten
tungsten is very high in cost and lacks flexibility. In case of this, resin mixed tungsten may be a better choice in terms of cost and flexibility to shield radiation.
Pure tungsten crucible
One of Nuclear resarch laboratories was in need of crucible made out of pure tungsten. We grinded roughly 10mm diameter pure tungsten rod. It has wall thickness of 0.2mm.

Sterilization・Heat treatment
Germicidal device equipped with UV lamps are widely used in variety of areas of business incluing food industry, semiconductor industry, printing industry. In Japan, it is quite popular to use germicidal device at hot spring facilities to purify hot water in the bath.
UV lamp, UV epuipment
Germicidal equipment using UV ray generally uses UV lamp. tungsten electrode and filament are widely used for these lamps.
Halogen heater・High temperature furnace
Halogen heater lamps are equipped with coating drying line in many factories. Such heater lamps are designed to enhance efficiency using infrared areas of light wave. Tungsten has highest melting point of all metals. It also has property of low vapor pressure, low thermal expansion, and good thermal conductivity. It is an ideal material for high temperature vacuum furancace.

filament coils and electrodes for UV
Light source for UV lamps, filament and electrode, is one of our main products. In order to increase life span of lamps, we add special heat treatment here at Takeishi Electric. To have a better discharge property, we mix emitter into electrode material, or we can coat emmiter material to the electrode.
Halogen heater coil
When heater lamp is operated, filament coil reached to extremely high temperature. In order to prevent filament deformation at high temperature, we use doped tungsten such as potassium tungsten. Non-sag and longer life halogen heater filament coils are rechrystalization treated filament aimed at not deforming when operated under high temperture.

General lighting
World is still lit with conventional lamps. Incadescent lamps, halogen lamps and Kripton lamps that have filament coils, and high pressure mercury lamps, sodium lamps, metal halide lamps are still used in many applications.
Halogen lamps・Metal Halide lamps.
When color rendering, atmospher and other needs are there, there are still people prefer conventional lamps.
Stage and Studio lamps・Sports lighting
For FIFA official football stadiums, MLB Major league ballparks, concert halls, movie shootings, high wattage discharge lamps are still the main stream.

Electrode made of high purity 5N material.
When operated, inner pressure of arctube for UHP lamp exceeds 200. Tiny impurity human eyes can not catch may lead to lamp to blacken, or exprlode in the worst case. With one of Japanese tungsten material suppliers, we have co-developed super high purity 5N tungsten material which best suit to UHP lamps.
Halogen lamp for special purpose・LED

People usually think tungsten and rare metals are industrial use, but these materials are widely used among us. Especiall for hobby, you find these materials very near to you.
Fishing lure and weight
Almost all states in U.S.A, lead materials are banned to use for the fishing weight. Tungsten weight is slowly but steadily drawing attention of anglers.
Darts Barrels
tungsten heavy alloy are used for darts barrels. Specific gravity of tungsten heavy alloy may be adjusted according to players touch, barrel forum, or total weight.

Research institutes and others
At school, we never liked homeworks or assignments. But heare at Takeishi Electric, our R&D group always search for opportunity to receive homeworks. Not only from industrial field, we welcome homework or joint development offered from schools and institutes. Our knowledge is not limited to machining, we seek our opportunity in "Porus tungsten", "Shintering material", "Reisn + metal material", "Ceramic coating", "Low function material (developing materials, coating materials, impregnating materials)
Low work function material to enhance discharge property.
We are seeking the opportunity to develop or joint develop low function materials, such as barium oxide (and other oxide) impregnated or coated materials.
