To attain a more comfortable lifestyle for next age, we develop suitable products such as an "induction-heating (IH) cooking heater for all metals" and "ultra-thin LCD TVs". In those household appliances, improving performance and functionality are essential.
To accelerate research and development of those products, we make full use of analysis technologies over inverters and power supplies.

Induction-heating (IH) cooking heater for all metals
By using electromagnetic-field analysis technology, we reduced energy-loss between the induction coil and metal pans. At the same time, we proposed a high-efficiency converter circuit system by means of circuit-analysis tools.
Our IH cooking heater directly heat every type of metal pans such as aluminum, copper, and cast-iron ones. Temperature of the top-plate surface never exceeds that of the bottom pan. Only our "Pure IH" has this great feature that easily keep clear surface of the top-plate.
Ultra-thin LCD TVs
We developed an ultra-flat and low-loss transformer by means of transformer-design technology. And also by using circuit-analysis tools, we achieved more efficient and slim power-supply unit.
We are engaged in extensive research and development ranging from elements up to systems. Those technologies contains such as circuit control systems, development of components, and investigation of packaging structure.
