Title: Power factor improving converter circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M7/06
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To improve power factor and power converting efficiency of the power supply circuit to realize reduction in size and weight of a circuit by providing a double voltage rectifying circuit and a current resonance type switching converter and a power factor improving means. SOLUTION: A series resonance current flows into a series resonance circuit and its switching output is supplied to a primary coil N1 of a converter transformer CTV. With the superimposed element of the switching voltage, a rectifying current flowing into the rectifying diodes D11 , D12 as the high speed recovery diodes is intermitted in the switching period. Thereby, a charging current flows into the smoothing capacitors C iA and C iB even in the period where the rectified output level is lower than the voltage across the smoothing capacitor. As a result, a mean waveform of the AC input current IAC is approximated to an AC input voltage VAC to expand the continuity angle of the AC input current to improve power factor. Thereby, power converting efficiency can be improved.

Title: Satellite broadcast receiving method
Inventor: DOUMURA TATSUAKI
IPC: H03J7/02
Filed: 1987-12-18
Abstract: PURPOSE:To obtain a satisfactory receiving characteristic by executing a fine adjustment of an oscillating signal by eliminating the influence by a diffusion signal. CONSTITUTION:When a vertical synchronizing signal from a vertical synchronizing separator circuit 48 is inputted to a microcomputer 52, the microcomputer 52 outputs a reset signal, and also, operates a first timer of the inside. A counter circuit 50 is reset by a reset signal and starts newly to count a second intermediate frequency signal, and the microcomputer 52 recognizes the end of a period when the first timer counts a prescribed value, and inputs a counted value of the counter circuit 50. Since this counted value corresponds to the second intermediate frequency, the microcomputer 52 detects a shift by comparing this counted value and a reference value which is stored in advance, and controls a PLLIC 22 so as to correct said shift. In such a case, the microcomputer 52 inputs the counted value continuously four times, and detects a shift by comparing an average value of said value and a reference value. In such a way, the influence by a diffusion signal can be eliminated.

Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To shorten the data reading processing time and also to improve the reliability of data to be transferred to a host device by comparing the data contents of data blocks which have been read by the first and second data storing means with each other. SOLUTION: The data transferred from a disk storage 9A or 9B that are read earlier are switched in every block and transferred to a host device 10. At the same time, the end of the reading processing is reported to the device 10 when the reading end report of the storage 9A that has read earlier the data on all blocks related to the read commands is received. Meanwhile, a comparison circuit 6 successively checks whether the contents of data on the blocks read by both storages 9A and 9B are equal to each other. Thus, the correctness of data which are read out of the storage 9B that has not received the reading processing end report can also be assured.

Title: Rotation drive device
Inventor: SATO ICHIRO
IPC: F16H1/10
Filed: 1988-12-21
Abstract: PURPOSE:To enable provision of high output torque with high efficiency without needing a high force even during overload running by a method wherein a disc shaft from an input means, a composite gear engaged with the static internal gear of the disc shaft, and a second step gear driven by the composite gear are respectively eccentrically rotated. CONSTITUTION:A rotation input to a crank arm 2 is transmitted from a disc plate 3 and a disc shaft 4 to a gear mounting plate 6, which is eccentrically rotated around a crank shaft 1. Along with rotation of the crank shaft, a support wheel 15 and a composite gear 12 are eccentrically rotated around the shaft 1, and is revolved along a static internal gear 17. In this case, since the gear 12 has an internal gear 14 engaged with the internal gear 17, it is driven at a speed higher than a revolving speed in a reverse direction to an eccentric rotation direction. Rotational movement of the gear 12 is transmitted from the internal gear 13 to a lower stage gear 11 of a second step gear 9. Since the gear 9 is revolved in a reverse direction to its rotation direction along rotation of the mounting plate 6, high-efficient speed increase is effected. Rotation of the gear 11 is transmitted to a gear 10 to rotate an external gear 8, the gear 8 serving as a planetary gear drives an internal gear 19 to transmit its rotation to a chain wheel 21 to drive rear wheels.

Abstract: PURPOSE:To enable the highly reliable and highly precise detection of gas for a long time, by a method wherein a detection level control element which can set a detection level beforehand is constructed so that it resets the detection level on the basis of a time required for starting oscillation. CONSTITUTION:An output signal from a gas sensor 1 at the time when an operation temperature of a heater element 3 is a rated operation temperature T1 is detected 12 and compared 13 with a detection level set beforehand by a detection level control element 11.

Abstract: PURPOSE:To obtain the high speed logic simulator by composing an equivalent logic circuit of at least three stages of logic, i.e. a NOT means, an AND means, and an OR means, and processing data by plural processors in parallel through a simulator part with a single instruction stream. CONSTITUTION:A preprocessing part 10 receives data 12 which indicates a logic circuit to be simulated in specific form. Conversion data 13 which indicates circuits in the form of the three stages of logic, i.e. the NOT means, AND means, and OR means are passed to the simulator part 11.
