Title: Side lid type ball screw device
Inventor: EBINA SHIGERU
IPC: F16H25/22
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To smoothly transfer a ball between a load region and a non-load region by moving a connection body by each ball in the load region, guiding each ball by the connection body in the non-load region, and forming a guide part which guides the ball to a conversion passage in each direction at both ends of the non-load region communicated with the load region. SOLUTION: Four belt parts of a ball connection body having an end 4 are slidably fitted in a ball return hole 7 to form a guide groove bar which guides a connection body 10 thereof. Moreover, a guide part which is linearly continuous with a load transfer groove 6 side in the direction of tangential line along a lead angle is formed in a direction conversion passage 8. A ball 9 of the ball connection body having an end 4 is transferred while applying load between a ball transfer groove 5 and a load transfer groove 6, escapes from the load region constituted by the load transfer groove 6, and enters the guide part. The ball 9 is guided to the connection body 10 of the ball connection body having an end 4 from this instant.  It moves in the direction of tangential line along the lead angle of the load transfer groove 6, leaves the ball transfer groove 5, and enters the direction conversion passage 8.

Title: Voltage type self-excited converter
Inventor: TANAKA SHIGERU
IPC: H02M1/06
Filed: 1994-08-31
Abstract: PURPOSE: To improve conversion efficiency by connecting an auxiliary snubber diode and an auxiliary snubber resistor in parallel between the node of first and second arc self-extinguishing elements and the negative-side terminal of a DC voltage source and connecting an auxiliary snubber circuit in series. CONSTITUTION: When a load current Iu is made to flow through an output terminal U, a current being made to flow through an anode reactor LA is made to reflux on the path of LA→DS→DT→LA when an element S1 is tuned off, and energy stored in LA is consumed by the resistor RT. When the element S1 is turned on, the voltage of a snubber capacitor CS is discharged through DT, RT and LA, and consumed as heat energy. When S2 is turned on and the load current Iu is made to flow in the opposite direction, the load current Iu is made to flow through CS→DT→CT while being made to flow through the diode Dss and capacitor Css of an auxiliary snubber circuit when the element S2 is turned off, but the capacitor capacity of the snubber circuit to the upper and lower arm elements S1 , S2 can be equalized. Accordingly, conversion efficiency can be improved.

Abstract: PURPOSE:To rewrite at dropout by demodulating a signal read from an optical disc by a demodulation circuit, inputting the result to a synchronizing circuit and applying error correction to a synchronized signal by an error correction circuit. CONSTITUTION:When information is writen on an optical disc 4, a data is read just after the write to confirm whether or not the data is written correctly and the data is fed to a demodulation circuit 5 and demodulated. The demodulated data is inputted to a synchronizing circuit 6, which detects information data and P, Q parity based on the address mark, the result is fed to the error correction circuit 7 and when the confirmation flag is set, the correction is applied. A comparatively large dropout generated on the disc 4 appears frequently along the track. Then the correction line of an RS 1 is formed in a direction along the track of the disc 4 and the correction line RS 2 is selected nearly to a direction vertical to it. Thus, even when a burst error due to dropout takes place, rewrite is applied and the data is stored more surely.
