Title: Ignition timing controlling apparatus for internal-combustion engine
Inventor: SHIBUKAWA SUETAROU
IPC: F02P5/155
Filed: 1982-02-08
Abstract: PURPOSE:To enable to operate an internal-combustion engine efficiently at a high speed, by controlling the ignition timing according to a preset engine speed. CONSTITUTION:Since the charging time of capacitors 46, 53 is decreased along with increasing of the engine speed, the potential drops in proportion to the speed of rotation. When the potential of a second triangular-wave generating circuit 4 becomes equal to the DC bias voltage V of a first triangular-wave generating circuit 3, the ignition timing that has been advanced is delayed at a rate determined by the integration time constant of a resistance 29 and a capacitor 31. When the speed of rotation is increased further to a prescribed value N2, the ignition timing is delayed rapidly. However, if the ignition timing continues to delay in the above rate, the delay of the ignition timing becomes too great at the speed of rotation higher than a value N3, and the engine output is not utilized efficiently. In this connection, there is provided a circuit 7 for cancelling delay of the ignition timing in an igniting circuit 6 and thereby advancing the ignition timing. With such an arrangement, it is enabled to operate an engine efficiently in its high-speed operational range.

Abstract: PURPOSE:To perform reproduction at the same speed with recording by comparing a playback frame address obtained from a playback signal with a reference frame address which varies at a reference period and controlling the feed speed of a recording medium so that the difference between the both becomes constant. CONSTITUTION:When the traveling speed of the tape is equal, the reference frame address from a reference frame address generating circuit 10 is generated at the same timing with a head switching signal RFSWP. Then when the tape travels at a normal speed, the reference frame address and playback frame address are so controlled as to coincide with each other, and a subtracting circuit 7 measures how much a current traveling speed deviates from the normal tape traveling speed. Namely, the subtracting circuit 7 measures the deviation in tape traveling speed, but the value is obtained as a frame address difference and a signal corresponding to the difference is processed by PWM and supplied to a capstan driving motor 20 to perform control. Consequently, the speed of the tape is equalized to that in recording and reproduction is performed stably.

Abstract: PURPOSE:To suppress an increase in the parasitic capacity of a PN junction by providing a first conductive layer of a FET structure, a second conductive well that covers a part thereof but is not completely depleted, and an electrode that provides an electrical potential externally to the well. CONSTITUTION:In a injection forming a P-type well 12, injection is performed so as for a part of thereof to extend outside an N-type injection part, and an extension well 12b is formed. On this extension well 12b is provided an electrode 16, and a proper potential is provided to the well 12. Since the electrode 16 is electrically connected to the P-type well 12b extending to the outside of an area forming an FET in this way, when this electrode 16 is connected to a source electrode 13 and the P-type well 12 is grounded, charges stored in the PN junction are discharged outside the FET. As a result, switching malfunctions can be prevented. Moreover, the small increase in capacity enables the density of the well 12 to be high, thereby suppressing a short channel effect.
