Abstract: PURPOSE: To perform efficient lubrication to an Oldham's ring and block side key grooves by forming oil detour grooves, passing across the moving parts of Oldham's ring oscillating side claw parts, in an Oldham's ring storage groove. CONSTITUTION: Oil detour grooves 80 are formed at the contact oscillating parts of an Oldham's ring storage groove 32 and one side face 71a of an Oldham's ring 70, specially in the moving ranges of burrs 72a, 72a by the oscillation of an Oldham's ring 70. Accordingly, at the time of lubricating oil moving from the displacement reducing side to the displacement enlarging side by the movement of the Oldham's ring 70, the lubricating oil can make a detour around the burrs 72a, so that the lubricating oil can flow to an intake space 41 from the inside of the Oldham's ring 70 via block side key grooves 32b. Sufficient lubricating oil can thereby be fed efficiently to the block side key grooves 32b, and the contact oscillating part of the Oldham's ring 70 and the storage groove 32 can be also lubricated sufficiently.

Charges are hardly injected to a base region from the base of the emitter region 6-1, and high hFE is obtained by the reduction of base currents and reactive currents flowing through a P type silicon substrate 1. A lateral type PNP transistor having high hFE is acquired, and the method is available for improving characteristics such as the low distortion factor of a power IC, etc.

Filed: 1978-05-04
Abstract: PURPOSE: To prevent consuming of surplus power in a display circuit and improve operating characteristic by connecting a main switch and a display switch in series and providing a third switch cooperating with the main switch.  
     CONSTITUTION: A switch S 3  is so constituted that it goes ON together with a main switch S 1  while its traveling contact 14 moves from the OFF position to the ON position and goes OFF while the traveling contact moves to the ON position. Since a display switch S 2  is connected in series to the main switch S 1 , the display circuit will not operate at times other than when both are ON. To operate the display circuit necessitates operation twice of the switches S 1 , S 2  but the switch S 3  goes ON for a short time and gives an operation command to a timing circuit 12 during charging of the switch S 1  to the ON position and therefore it turns out that the display circuit 11 operates even if the switch S 2  is not operated.

Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To allow the circuit to trace a synchronizing signal in a modulation signal by capturing the synchronizing signal without the use of a DLL and a PLL. SOLUTION: After the start of receiving a high frequency signal, a sampling circuit 32 samples a modulation signal S1 with all clock signals S3 generated by a clock generating circuit 31 respectively to generate a plurality of sampling signals. A correlation calculation circuit 34 calculates the correlation value between each sampling signal and a spread signal and the correlation value in matching with a specific correlation value among all calculated correlation values is selected by a maximum correlation selection circuit 39.  A phase selection circuit 41 based on the selected correlation value selects a synchronizing clock signal synchronously with the modulation signal S1 or a lead phase clock signal and a delay phase clock signal whose phases are close to the phase of the synchronizing clock signal to allow the circuit 31 to stop production of other signals than the three signals. Then the circuit 32 generates respectively the sampling signal with the three signals, the circuit 34 calculates the correlation value of each signal and the circuit 39 selects the correlation value in matching with the specific correlation value.
