Title: Digital receiving circuit
Inventor: NAGABORI TAKESHI
IPC: H04B10/50
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To enable full DC coupling and facilitate one-chip integration, using a minimum number of components by controlling the offset and input impedance of a differential output amplifying circuit according to differential outputs. SOLUTION: The in-phase output and opposite-phase output of a differential amplifier 2 are branched and inputted to peak detecting circuits 5 and 6, which detect and hold the peak values of in-phase output pulses and opposite-phase output pulses. The difference voltage between the held peak values of the in- phase output and opposite-phase output is amplified by an operational amplifier 7 and led to the base of a transistor 4. The offset is controlled according to this difference voltage. Further, a means value detecting circuit 8, consisting of a resistance voltage-dividing circuit, obtains the mean value of the in-phase output and opposite-phase output of the differential output amplifier 2. This mean value is compared by an operational amplifier 10 with a low-voltage source 9 and then amplifier and led to the base of a transistor 3.  The input impedance is controlled according to this comparison result.

Filed: 1995-06-27
Abstract: PURPOSE: To suppress a high frequency signal from leaking at low cost by shorting all the base regions of a MOS transistor on the same substrate. CONSTITUTION: Gate electrodes 17A-17d of MOS transistors Q1-Q4 have a common gate terminal G. When a gate signal is applied to this terminal, a voltage is applied through gate oxide films 18a-18d to form channels having a different conductivity from a semiconductor substrate 10 between adjacent, drains and sources in this substrate 10 which form base regions of the four MOS transistors disposed on its surface and the base regions are shorted in structure and may be shorted with a low-resistance wiring material such as A1. Thereby, a semiconductor switch device having parasitic capacitances of the MOS transistors can be produced at less cost than that of the conventional one.

Abstract: PURPOSE:To confirm the operation of a switch by an inexpensive constitution, by connecting one end of an optical fiber flux to a display part by connecting it to the output side of optical fiber fluxes of the input side and the output side which are opposed by placing a member for shading a light selectively between them. CONSTITUTION:A push button 3 is floated by a spring 4, a light beam emitted from a light emission device 6 is led to an optical fiber 7 through an optical fiber 5, the light is photodetected by a photodetecting device 8, and simultaneously the light beam is led to a display fiber 9, too, and since its tip end emits light, it is displayed that a switch is conducting.

Abstract: PURPOSE:To raise the responsiveness of an optical system feed servo-system by providing a jump pulse generating part, a jump pulse smoothing part and an adder, and correcting a delay of an input signal to a motor by a filter at the time of quick traverse reproduction. CONSTITUTION:At the time of the quick traverse reproduction, a tracking direction pickup driving signal VT inputted to an input terminal 1 becomes a lamp wave which is varied quickly in proportion to frequency of an inter-track jump, and an output of a filter 2 becomes lower by a voltage DELTAV proportional to a variation speed of VTand a time constant of the filter than VT. On the other hand, a jump pulse generated from a jump pulse generating part 8 becomes a DC voltage proportional to frequency of a jump pulse by a jump pulse smoothing part 9. The DC voltage can be made equal to DELTAV by setting suitably an amplification factor of the smoothing part 9, and by adding this voltage and the output of the filter 2 by an adder 10, a signal for correcting a delay by the filter 2 is obtained, and the responsiveness of a servo-system is raised.
