Title: Microwave receiving device
Inventor: ARAI MASAMI
IPC: G01R29/08
Filed: 1988-06-20
Abstract: PURPOSE:To realize the continuous and highly accurate measurement of the electric field intensity of a received signal by converting the AGC control voltage of plural variable gain amplifiers which are cascaded and controlled independently of each other into the gains and obtaining the general gain via an arithmetic circuit for calculation of a reception electric field. CONSTITUTION:A variable gain amplifier 8 serving as a high frequency amplifier has its output converted into an intermediate frequency via a frequency converter 9. A variable gain amplifier 10 serves as an intermediate frequency amplifier. The initialization is applied at first to a control part, etc., and the A/D converters 131 and 132 are actuated by the control signals 141 and 142 respectively. Thus the AGC control voltages 121 and 122 are converted into the digital signal. The end or incompletion of the A/D conversion is decided by both signals 141 and 142. If the A/D conversion is not through yet, the A/D conversion is continued. Then a microcomputer 14 reads the outputs of the converters 131 and 132 and adds them together to calculate the general gain. The microcomputer 14 calculates a reception electric field from the general gain and a known output level and displays the result of this calculation on a display device 15.

Title: Electrostatic drive and vibration-type sensor circuit
Inventor: TOYODA SHOJIRO
IPC: G01P15/08
Filed: 1994-07-04
Abstract: PURPOSE:To control the amplitude of the output signal of a sensor without controlling the amplitude of an exciting AC voltage by a method wherein the output of the sensor is rectified and fed back to the sensor in such a way that the amplitude of the output signal of the sensor becomes constant. CONSTITUTION:A vibration gate-type element (RGT) outputs a current i0 whose phase is advanced by 90 deg. in a resonance point with reference to an exciting voltage V1. A current-to-voltage converter which is formed of an operational amplifier 11 converts the AC current i0 into an AC voltage v0 so as to be output to a rectifying circuit 7 and a phase correction circuit 8. The rectifying circuit 7 rectifies an AC voltage V0 so as to output to the noninverting terminal of an operational amplifier 9. The phase correction circuit 8 corrects the phase of the AC voltage V0 in such a way that the open loop phase of an exciting loop becomes 0 deg. so as to feed back to a gate G for the RGT via a capacitor C. The operational amplifier 9 amplifies the difference between the output voltage of the rectifying circuit 7 and a set voltage VA in such a way that the open loop gain of the exciting loop becomes 1 and that the amplitude of the AC voltage V0 becomes constant, and the amplified difference is is output to the noninverting terminal of the operational amplifier 11 as a DC bias voltage.

Title: Parallel a/d converter
Inventor: MATSUZAWA AKIRA
IPC: H03M1/20
Filed: 1990-06-11
Abstract: PURPOSE:To reduce distortion against a high frequency signal and to reduce the cost at a fast speed with high accuracy by providing a reference voltage generating and interrupting circuit, a differential conversion circuit array, an interpolation circuit array, a comparator array and a logic processing circuit on this A/D converter. CONSTITUTION:Each voltage fed to an input terminal of each comparator 6 is given to a differential conversion circuit 1, in which a potential difference between an input signal 2 and each reference voltage 3 is amplified and a dispersion in the comparison voltage of each comparator 6 is caused through the decrease by the gain of the differential conversion circuit 1 at the input terminal. Thus, even when a comparator with 8-bit resolution is in use, 10-bit resolution is available when the gain of the differential conversion circuit 1 is set to >=4. Moreover, since only the differential conversion circuit 1 is connected to the input signal 2 and a reference resister array 4, the level of the connecting point of the circuit with respect to the input signal and the reference resistor array is decreased to 1/4 - 1/16 of that of a conventional A/D converter. Thus, the input capacitance and the input bias current are considerably decreased, the drive of a high frequency input signal is easy, the distortion is reduced and the conversion accuracy is improved.
