Title: Control circuit for multiple-voltage power converter
Inventor: KUMAGAI SATOSHI
IPC: H02M7/48
Filed: 1996-08-14
Abstract: PROBLEM TO BE SOLVED: To improve the power factor of a control circuit for multiple-voltage power converter when a multiple-voltage power converter supplies AC power to a capacitance load by installing a specific-pulse increasing circuit to a single- phase voltage type inverter and accelerating the rise of an electric current by making the first ripple pulse immediately after the voltage polarity is switched specially larger. SOLUTION: Since a specific-pulse increasing circuit 40 is added to a second inverter 4, a pulse can be added to or deleted from the V-phase signal of the inverter 4. In the output voltage of the inverter 4, the magnitude (peak value) of the leading pulse immediately after the voltage polarity is switched becomes larger for a prescribed period and the large pulse appears at both ends of the serially connected secondary windings of two transformers 5 and 6. Therefore, the power factor of a control circuit for multiple-voltage power converter can be improved and the size of the converter can be reduced as a whole.

Title: Optical information recording and reproducing device
Inventor: SHIKICHI SATOSHI
IPC: G11B7/09
Filed: 1988-08-31
Abstract: PURPOSE:To always enable the recording and reproducing of normal information by generating a servo error signal with using a means to generate the signal of a constant value when one of plural sensor signals shows an abnormal value. CONSTITUTION:One servo error signal to be used for tracking or focusing is generated from plural sensor signals A1 and A3. In the case of the tracking or focusing, when one sensor signal A1 shows the abnormal value by the defect of a tracking track, for example, the means separately provided to generate the signal of the constant value generates the signal of the constant value instead of the sensor signal A1, which shows the abnormal value, and operation can participate in the generation of the normal servo error signal. Thus, even when one of the plural sensor signals A1 and A3 shows the abnormal value, the normal servo error signal can be always generated and without generating conventional servo dislocation, the tracking or focusing can be satisfactorily executed.

Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent wear caused by the movement of a backup ring of a double seal and to dispense with retrieving the oil to a drain chamber. SOLUTION: A rod seal 33 and backup ring 34 are accommodated in an internal circumferential groove 32 at a rod guide 23 of a hydraulic cylinder 22 to form a double seal on the high pressure side, an oil seal 24 is provided on the low pressure side, and between them an oil sump 31 is formed. The oil sump 31 communicates with a part of groove 32 on its cylinder 2 side via oil paths 37 and 38, and the path 37 is provided with a check valve. When the pressure of the oil passed through the rod seal 33 and stored in the oil sump 31 becomes higher than the internal pressure of the cylinder 2, the check valve is opened to cause the oil to flow into the groove 32. The backup ring 34 is pressed always toward the upper guide 27 by the internal pressure of the cylinder 2 or oil sump 31 and is free from risk of moving.  Because the oil in the oil sump 31 is returned to the cylinder 2, a drain chamber is not necessary.

Title: Disk reproducing method
Inventor: TAMAYA TSUNEHARU
IPC: G11B19/02
Filed: 1988-08-30
Abstract: PURPOSE:To execute prompt reading and reproducing operations by reading the contents information of a disk having a display symbol with the second rank and after that reading the contents information of another disk having another display symbol with the first rank. CONSTITUTION:For example, when both disks A and B exist, a pickup 19 first reads the contents information of the disk B and next reads the contents information of the disk A. Consequently, since the pickup 19 is positioned at the inner circumferential position of the disk A when the pickup 19 ends the reading of the contents information, the pickup 19 can promptly shifts to the reproducing operation for the disk A when the disk A is to be reproduced next. Further, since the pickup 19 is positioned at the neighborhood of the innermost circumferential position of the disk B when a tray 8 executes opening and closing operations, the pickup 19 can promptly read the contents information of the disk B continuously after the opening and closing operations of the tray 8. Thus, the prompt contents information reading and reproducing operations can be executed.

Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To make reception data in a base station hold the orthogonal relation of an orthogonal code and to synchronize reception signals by compression- encoding the advance/delay information of the time calculated so as to match the synchronization of the orthogonal code of the reception signals from respective mobile stations and transmitting it to the mobile stations. SOLUTION: Output is passed through a parallel/serial converter 407 and turned into serial data. To the data, noise equivalent to a time difference with the reception data from the surrounding mobile station is superimposed. The data are judged by using a judgement device 409. Noise signals are used and delay time is predicted by using a delay time control signal predicting device 411. The predicted delay time difference is encoded and transmitted from the transmitter of the base station to the respective mobile stations. The signals are turned into input signals to a receiver and the timing of the transmission signals of the respective mobile stations is adjusted. Thus, the orthogonal codes used as the spreading signals of the data in the respective mobile stations are synchronized.
