Filed: 1991-10-03
Abstract: PURPOSE:To obtain the base band output of a constant amplitude value to input signals with different modulation degree in a satellite broadcasting receiver. CONSTITUTION:A high frequency signal inputted from an input terminal 1 is converted into an intermediate frequency signal by a tuner part 4. After the band is limited by a filter part 5, it is inputted to a demodulation part 6. The inputted signal is converted into a base band signal(for example FM modulation), amplified and inputted to a gain control amplification part 7, and outputted from an output terminal 2. In this case, the gain of the gain control amplification part 7 arranged on the output stage of the base band signal is controlled by the control signal inputted from the outside to a control signal input terminal 3.

Title: Semiconductor acceleration sensor and its manufacture and testing method
Inventor: KAMIYANAGI KATSUMICHI
IPC: H01L29/84
Filed: 1994-10-21
Abstract: PURPOSE: To obtain a semiconductor acceleration sensor of high reliability which can be easily manufactured and calibrated, by providing a weight and a supporting frame, composing the sensor of a silicon detecting body and a glass base, and forming a gap part. CONSTITUTION: A weight 12 of a silicon detecting part 10 freely shifts by an acceleration. A squeeze film effect is caused in a gap between the weight 12 and a glass 20. Owing to this effect, a damping operation acts on the motion of the detecting body 10, so that the resonance of the detecting body 10 is suppressed. Moreover, a potential of a substrate of the detecting body 10 is connected to a potential of a feed power source to a Wheatstone bridge or a ground potential by a penetrating part 15 formed in a supporting frame 16 of the detecting body 10. A wiring is taken outside from a conductive film 21 formed at the glass, e.g., by wire bonding or the like manner. In this constitution, the static electricity is produced between the lower surface of the weight 12 and the glass 20 below the weight 12, which can be used as a pseudo acceleration to calibrate the acceleration sensor.

Filed: 1986-10-29
Abstract: PURPOSE:To prevent the jumping of a brush without increasing the compressive force of a spring by combining a plurality of elastic materials having different elastic moduli and pressure-welding the brush to a slip ring. CONSTITUTION:An energizing means 20 on the positive side consists of a rubber member 32 fitted on a bottom in a brush receiving hole 22, a compression coil spring 33 arranged between the rubber member 32 and a brush 16 and a tabular overlap 34 disposed between the rubber member 32 and the compression coil spring 33.
