  • Publication number: 20070119257
    Abstract: A vibration detection system comprises a battery-less vibration sensor and an interrogator. The sensor comprises a single port surface acoustic wave resonator. The interrogator continuously transmits a carrier wave signal to the resonator while receiving a wave signal reflected from the resonator. The reflected wave signal includes components other than the transmitted carrier wave signal if the sensor senses a vibration event. Based the reflected wave signal, the interrogator judges whether the vibration event occurs.

  • Publication number: 20060090704
    Abstract: In a plasma processing apparatus, electromagnetic waves are radiated from slots of waveguides into a processing chamber via dielectric windows that are supported on beams, thereby generating a plasma. A substrate, which is an object of processing, is processed by the generated plasma. Dielectric plates are attached to those surfaces of the beams, which are opposed to the processing chamber. The thickness of each dielectric plate is set at ½ or more of the intra-dielectric wavelength of the electromagnetic waves. Using the plasma processing apparatus, a large-area processing can uniformly be performed.

  • Patent number: 6996240
    Abstract: A loudspeaker unit which requires no particular procedure for correction of the acoustic characteristic even if the installation environment of the loudspeaker unit changes, and which can correct, in addition to the frequency characteristic, a sound lag and a phase shift ascribable to the reverberation and an echo of a sound. The loudspeaker unit picks up a sound regenerating from the loud speaker with a microphone, and compares in real time a sound from a sound source with a regenerative sound, referring to a difference therebetween, with reference to the characteristic at an optional frequency and the characteristic of the reverberation or the echo each including the delay time, respectively, and corrects the signal to be sent to the loudspeaker by the result of arithmetic.

  • Patent number: 6429544
    Abstract: An electrical equipment module is mounted in, for example, an electrically-powered seat unit for a vehicle. Multiple wire groups (52-56) comprised of wire harnesses or flat cables are led out of a module body (51) of the electrical equipment module (50) from different sides of the module body, thus reducing the outside diameter and thickness of each wire group so that the module body is thin and suited to be mounted in narrow layout space under a seat. By mounting, to the module body, a connector for connecting a printed circuit board (51m) in the module body to an external power supply or an external sensor and by making complicated wiring between the connector and the printed circuit board (51m) in advance in the module body, an assembling (wiring) work at the time of manufacturing the electrical equipment module is simplified.
