Patent JP-H08163871-A (JP)
Title: Dc power supply circuit
Inventor: MORITA KOICHI
IPC: H02M1/14
Filed: 1994-12-05
Abstract: PURPOSE: To obtain a highly efficient DC power supply circuit having simple circuitry by providing rectifying devices connected, respectively, between one end of an output capacitor and one output terminal of a main rectifier circuit and between the other output terminal of the main rectifier circuit and the other end of the output capacitor. CONSTITUTION: In the DC power supply circuit, AC input voltage VIN from an AC power supply 1 is stepped down by an input capacitor 10 and applied to the input terminal of a full-wave rectification bridge circuit 11 and thereby the charging voltage VCO of an output capacitor 3 drops below the maximum level of the AC input voltage VIN. Since both diodes 12, 13 are conducting during an interval when the rectified output voltage VRO from a full-wave rectification bridge circuit 2 is lower than the charging voltage VCO, the charging voltage VCO is outputted directly as a DC output voltage VOUT. Since both diodes 12, 13 are not conducting during an interval when the rectified output voltage VRO is higher than the charging voltage VCO, the rectified output voltage VRO is outputted directly as a DC output voltage VOUT.  Consequently, the power factor can be improved and the efficiency can be enhanced through simple circuitry.

Title: Coincidence circuit
Inventor: NARAHARA MITSUMASA
IPC: H03K19/21
Filed: 1987-12-01
Abstract: PURPOSE:To simplify a circuit by using an '1' detecting circuit which can detect only that each bit of (n) bit and binary data and the corresponding output bit of a counter coincide at a value '1'. CONSTITUTION:In course of up-counting, when the whole bit (Dj) of the counter 1 coincide at the value '1' for the first time, the whole '1' detecting circuits (2j) detect the coincidence and a first coincidence discriminating circuit 3 executes discrimination output. At this time, the output value of the counter 1 is the same '1' as the (n) bit and binary data of which bit (Dj) is an object. Besides, as they coincide for the first time in the course of the up-counting, the bit (Dj) is made to be a minimum value among the numbers being '1'. This minimum value is obtained when the other bit are '0'. Therefore, as the whole bit of the (n) bit and binary data being the object are '0' except the bit (Dj), the time when the circuit 3 executes the discrimination output is the time when the (n) bit and binary data being the object and the output value of the counter 1 coincide. Thus, the circuit constitution can be simplified.
