Title: Cylinder for disc brake
Inventor: MATSUMOTO ATSUO
IPC: F16D65/18
Filed: 1978-08-24
Abstract: PURPOSE:To prevent a piston from being fastened with rust, by making the inside diameter of a lip part between a dust boot fitting groove and a piston seal fitting  groove larger than that of a cylinder chamber to provide a step part at the cylinder  chamber. CONSTITUTION:A groove 14 for fitting a dust boot 13 and another groove 16 for fitting a piaton seal 15 are provided at the mouth of the cylinder chamber 10. The lip part 17 is provided between the grooves 14, 16. The outsides diameter of the lip part 17 is made by 2l larger than that of the cylinder chamber 11.

Title: Ignition timing control device for engine
Inventor: FUJIMOTO TAKANORI
IPC: F02P5/155
Filed: 1983-06-08
Abstract: PURPOSE:To prevent after-firing and the like by providing a means to control the amount of delay angle in an ignition timing control device to give a delay angle to an ignition timing at the time of over speed. CONSTITUTION:For operating a control means 50 to bypass an ignition signal to the earth over a fixed number of revolutions at an engine revolution number N2, a voltage at an inversion input terminal of a voltage comparator 52 is set at an output voltage of an F-V circuit 51 corresponding to the revolution number N2. Thereby, the output of a comparator 17 is brought to a low level when the number of revolutions is under N2 and to a high level when over N2. Consequently, a transistor 54 is on when the number of revolutions is over N2. Therefore, when the collector of the transistor 54 is connected to bypass an output signal F of the voltage comparator 17, the ignition signal is not given to the gate of a thyristor 7 over the engine revolution number N2.
