Title: Synchronizing circuit
Inventor: INAGAWA JIYUN
IPC: G11B20/10
Filed: 1982-06-15
Abstract: PURPOSE:To detect a synchronizing signal and to protect synchronization for the lack of the synchronizing signal, by using a window output generated from a counter synchronously controlled by a synchronizing signal included in a digital input signal, a counter counting the window output and a gate circuit. CONSTITUTION:When an input signal consisting of one frame of N bits is inputted to a terminal 1 in each frame, a synchronizing signal detecting circuit 3 detects a synchronizing signal and outputs the signal to gate circuits 4, 10. An 1/N frequency divider 5 is cleared every time when the outputs of the gate circuits are turned to ''H'' and sends an output to an output terminal 9. The output of a window generator 6 is ''H'' during the period from the output of the frame synchronization controlling signal from the frequency divider 5 to several bits before and after the N-th bit of the succeeding output and inputted to the gate 4 through a selector 8. When the detecting circuit 3 is synchronized with the frequency divider 5, the output of the gate circuit 4 is turned to ''H'' and errors due to noises are prevented only when the output signal of the circuit 3 is entered into a window generated by the window generator 6. If the synchronizing signal is not detected because of dropout or the like, a counter 7 counts up the output of the window generator 6 and outputs the counted value to the divider 5.

IPC: B60C11/16
Filed: 1986-05-06
Abstract: PURPOSE:To prevent the breakage of a road surface and nuisance caused by dust in a spike pin for an automotive spike tire, by forming a main body with a two-way shape memory alloy, thereby extending the spike pin at the time of low temperature, and shortening it at the time of high temperature. CONSTITUTION:A main body 1 is formed with a two-way shape memory alloy so that an over-all length L extends in the low temperature of approximately less than five degree, while the over-all length L shortens in the high temperature of approximately twenty-five degree or more. With this arrangement, when the open-air temperature and road surface is above a predetermined temperature and, even in low temperature, the road surface is dried so that the temperature rises due to the generation of heat in a tire, the main body 1 is shortened so that a spike pin is not operated, to be function as a normal tire. Conversely, if the tire temperature becomes low, the pin projects. Therefore, it is possible to prevent the breakage of the road surface and generation of dust.
