The electronic components segment is extremely broad, encompassing a range of operations from the production of ceramic element materials and a variety of transformer components, to the production of end products such as battery chargers. Products are supplied widely to the general home appliance, industrial machinery, medical equipment and even space exploration equipment markets. The segment serves an ever-changing market and actively responds to the various needs of society through initiatives that include environmental measures relating to the chemical content of products and the introduction of low-power and energy-saving products such as LED lighting.   The Tamura Group's electronic components are everywhere. Our reactors1, for example, are employed in air conditioners. Inverter air conditioners, which allow subtle temperature adjustments, currently dominate the market. Their inverters switch on and off repeatedly at very short intervals, generating noise that affects other electrical appliances. Reactors block out that noise. Our transformers are employed in laser printers, which are widely used in offices. Laser printers use static electricity to apply carbon toner and that requires extremely high voltage. One way to generate such a high voltage is through the use of piezoelectric ceramic transformers2. 1.   An electrical component that gives alternating current circuits inductive resistance. 2.   A boosting component that converts voltage using mechanical resonant oscillations. Power transformers; audio transformers; communication transformers; reactors; AC adaptors Tamura offers a wide variety of custom transformers suited to particular product development needs. They are employed broadly in home appliances, information equipment, industrial machinery and space exploration equipment. Automotive choke coils3 We have exploited the proper ties of magnetic metals to improve choke coil resistance to high temperatures and to reduce their size. Our choke coils are supplied to the automotive market for use in vehicles. 3.   Mounted in vehicle electronic circuits to help reduce electromagnetic noise. Thermal cutoffs4 As part of initiatives in chemical substance control, we created a series of thermal cutoffs that were among the first to comply with the Restriction of Hazardous Substances (RoHS) Directive. They are employed in a diverse range of electrical equipment. 4.   Melts above a certain temperature causing an electrical device to shut down to avoid overheating. LED lighting We have high expectations for our LED lighting business. A variety of products are being developed, including omnidirectional highdensity LED lamps, small high-density LED lighting in which light sources are linearly arranged, light guide flat-panel lighting and LED lamps with replaceable bulbs. In addition to meeting existing market demand for smaller, lighter, highly efficient products, we will need to respond to ever-increasing requirements for compliance with chemical substance regulations. The Tamura Group will pursue these initiatives proactively to fulfill its social responsibility. New piezoelectric ceramic plant completed In April 2007 a ceramics plant was established at the Saitama Plant that will facilitate an increase in the production of piezoelectric ceramics, the demand for which continues to rise in the notebook PC, laser printer and LCD television businesses. Plans are underway to expand this business as represented in our slogan, “Make the change! Piezo for high voltage!” Our focus will be on the office machine and LCD markets.
