Title: Switching circuit of differential amplifier pair
Inventor: KUDOU OSAMU
IPC: G05F3/26
Filed: 1982-11-08
Abstract: PURPOSE:To attain the adoption of a band gap reference less in the temperature dependancy to a reference voltage of the differential pair by constituting the titled circuit that the two differential pairs are switched by a couple of transistors(TRs) turned on or off exclusively. CONSTITUTION:Switching signals C, inversion C' being opposite phase are applied to the base of TRsQ51, Q52. TRsQ41, Q42 act like a constant current source. When the input C is at L level and the TRQ51 turns off, the TRQ41 is turned on and a differential pair DF1 is selected. Since the inversion C' is at H level, the TRQ52 is turned on and the TRQ42 is turned off and a diffierential pair DF2 is inoperative. On the contrary, when the input C is at H and the inversion C' is at L, the differential pair DF2 is selected. Thus, the value of a reference voltage VR given in common to the differential pairs DF1, DF2 is the sum of a collector-emitter voltage for one stage's share of the TRQ41, Q42 and a base-emitter voltage of one stage's share of TRsQ41, Q42, and the band gap reference with less temperature dependancy is adopted.

Title: Knocking preventing method of v-type eight-cylinder engine
Inventor: MURAI TOSHIMI
IPC: F02P5/153
Filed: 1986-08-22
Abstract: PURPOSE:To control an optimum ignition timing, by delaying an angle of a timing of one of cylinders to be ignited in advance at a minimum ignition timing in the same bank to control knocking of the other cylinder. CONSTITUTION:When knock sensors 18L, 18R disposed on right and left banks 25L and 25R sense knocking, a control circuit 26 delays an angle an ignition timing and when they do not sense the knocking, it advances the angle of the ignition timing. At the time, when knocking of cylinders in the same bank to be ignited at a minimum ignition interval is to be controlled, an angle an ignition timing of one of the cylinders is delayed in advance to prevent knocking and knocking of the other cylinders is controlled. With the arrangement, the interference of overlapped knocking signals is not caused to prevent a false discrimination of knocking. Therefore, knocking can be controlled without stopping knocking control of all the cylinders to control an optimum ignition timing.
