    摘要: A radio-frequency signal receiver and its manufacturing method are disclosed. A tuner receives a radio-frequency signal, and a demodulator receives an output signal from the tuner. An error corrector receives an output from the demodulator. A determiner determines whether or not an error rate supplied from the error corrector is not less than a predetermined rate. A controller receives an output from the determiner, and based on the determination, the controller controls a plurality of sections forming the radio-frequency signal receiver. The controller controls selectively one of the plurality of sections, thereby lowering the error rate. A manufacturing method of this receiver makes a memory, coupled to the controller, store a shift-amount of frequency corresponding to an interference signal in a pass-band of a narrow-band filter.

    摘要: An ultrasonic sensor detects the time of rise of the first of transmitted waves and also detects peak points Po appearing in the waveform of received waves to detect a waveform reference point where the time-base coordinate of a phantom envelope connecting these peak points Po is a minimum. The time T2 of rise of the first of the received waves is calculated by adding a predetermined period of offset time To to the time t2 of the waveform reference point of the received waves to calculate the elapsed time .DELTA.T from the time of rise of the first transmitted wave to the time of rise of the first received wave. The distance L to an object of measurement is calculated based on the result of calculation. The distance L to the object can be calculated alternatively based on the elapsed time .DELTA.T' from a waveform reference point of the transmitted waves to the waveform reference point of the received waves. The sensor thus realized gives measurements with high accuracy even with use of ultrasonic waves of relatively low frequency.

    摘要: A damping support structure for preventing vibrations of an apparatus table supporting an apparatus for manufacturing ultra-high precision devices such as semiconductors and printed circuit boards. The apparatus table is supported in suspension by support members, with its apparatus mounting surface disposed at a low level. The support members are supported by stationary members through vertically extendible and contractible first air springs. Horizontally extendible and contractible second air springs are disposed between the stationary members and the apparatus table. The first and second air springs serve to mitigate vertical and horizontal vibrations of the apparatus table, respectively. At the same time, in response to vibrations of the apparatus table detected by vibration sensors, air supply from air supply devices to inside spaces of the first and second air springs is controlled to apply controlling forces to the apparatus table through the first and second air springs for displacing the apparatus table relative to the stationary members and maintaining the apparatus table in an absolutely stationary state.
