  • Wireless response device, image forming apparatus, and equipment
    Publication number: 20060273904
    Abstract: A wireless response device comprises an antenna that receives a question signal, an identification signal generating unit that generates a response signal for a question signal received by the antenna, and that operates passively, and an impedance conversion unit provided between the antenna and the identification signal generating unit, whose impedance changes in response to the state of the environment.

  • Snubber circuit for power conversion semiconductor elements and assembly thereof
    Patent number: 5055990
    Abstract: A snubber network of high energy efficiency for use with power conversion semiconductors is described. Asymmetrical semiconductor elements are used to reduce and dissipate voltage spikes induced by stray inductance during turn-off of power semiconductors. A space efficient assembly using the described snubber network containing asymmetrical semiconductor elements and an external snubber capacitor is also described.
