Title: Cylindrical spike pin of automobile's snow tyre
Inventor: ARA MIYOKI
IPC: B60C11/16
Filed: 1983-04-08
Abstract: PURPOSE:To prevent a tyre from slipping and prevent the road face from damage by manufacturing the body of a spike pin out of steel in the cylindrical form and retractably inserting a pointed core in the cylindrical body via a spring so as to make the pointed core pushed out and retracted from the body according to the snow-covered condition and usual condition of road face. CONSTITUTION:A spike pin 2 is formed as that a pointed core 2 is retractably inserted in the cylindrical sleeve 1 which is made of steel and a spring 3 is mounted at the base part of the pointed core 2 inside the cylindrical sleeve 1. If a car drives on the road which is covered with snow or frozen, the pointed core 2 is made to be pushed out of the cylindrical sleeve 1 so as to effectively prevent the car from slipping. On the other hand, if the car drives on the usual state road, the pointed core 2 is retracted inside the cylindrical sleeve 1 so as to prevent the road face from damaged by the pointed core 2.

Abstract: PROBLEM TO BE SOLVED: To provide edge structure with high linearity in piston vibrations without enlarging the width or edge by forming pleats having regular peaks and valleys in circumferential direction at two semiarcuate parts of edge. SOLUTION: Concerning an edge 3 for supporting the outer periphery of long circular diaphragm 2, plural pleats are formed while V-shaping cross sections and having regular peaks and valleys in the circumferential direction on their outside and inside slopes so as to easily regularly crease two semiarcuate parts 3a in the circumferential direction. Further, the peaks and valleys of regular pleats provided outside and inside the V-shaped cross sections are mutually oppositely shifted and zigzag-shaped stretch parts are regularly combined in the circumferential direction. Concerning two linear parts of edge 3, the cross section is V-shaped similarly to two semiarcuate parts 3a. When a vibration system performs piston motion, the zigzag-shaped connection part is stretched so as to smoothly and regularly generate creases in the circumferential direction.

Title: Protecting circuit for phase locked loop
Inventor: SAKAMOTO HIROSHI
IPC: H03L7/14
Filed: 1987-03-18
Abstract: PURPOSE:To reduce the degree of a step-out due to the instantaneous interruption of a reference clock by utilizing the output signal of a voltage control oscillator as a reference input clock when the reference input clock supplied to a phase locked loop PLL is interrupted instantaneously. CONSTITUTION:A switch circuit 12 is changed toward to terminal 12b by a control part 13 within the instantaneous interruption period. Thus the output signal of a VCO 17 is applied to a phase comparator 15 as a reference input clock via the circuit 12 while this circuit 12 is kept at the side of the terminal 12b. Therefore the phase comparator 15 has no instantaneous interruption during the application of said input clock and the phase comparison is carried out between the output signals of the VCO 17. As a result, the step-out degree of a PLL 14 is extremely reduced.
