Title: Internal combustion engine
Inventor: YANAGI NORIO
IPC: F02B75/02
Filed: 1991-03-27
Abstract: PURPOSE:To speed up gasification of fuel and prevent blow-by of air-fuel mixture when an intake valve and an exhaust valve overlap each other. CONSTITUTION:A recessed portion 9 for constituting a combustion chamber 6 is provided on the intake side on the bottom surface 4a of a cylinder head 4, an intake valve 1 is arranged in the center of the recessed portion 9, and 2 exhaust valves 2 are arranged on the side of the bottom surface 4a. When the intake valve 1 is opened, fuel is injected from an injector 3 on the wall surface 9b of the exhaust valve 2 side in the recessed portion 9 to speed up evaporation, further, hot squish is generated from the exhaust valve 2 side. Since the wall surface 9a of the recessed portion 9 exists between the intake valve 1 and the exhaust valve 2, air-fuel mixture introduced into a cylinder 11 becomes difficult to blow-by. Exhaust is performed through 2 exhaust valves.

IPC: H04B1/10
Filed: 1982-04-16
Abstract: PURPOSE:To detect the presence/absence of signals before the end of processing of addition and averaging, by extracting information such as partial adding and averaging values during the processing of addition and averaging. CONSTITUTION:A prestage adding and averaging device 5 subdivides the total number of adding and averaging processings of signals A/D-converted by an A/D converter 2 as basic units and performs addition and averaging at the number of times of the basic units.

Filed: 1982-04-21
Abstract: PURPOSE:To prevent latchup of a C-MOS integrated circuit device by disposing a pair of p-channel MOSFET forming an inverter and n-channel MOSFET in channel width direction on a linear line. CONSTITUTION:The base length of p-n-p transistor Q1 forming a thyristor is increased, even if the interval between the well region WL and p-channel MOSFET is represented by WA, in the length of the channel width direction of the drain DP and gate GP of a p-channel MOSFET, thereby increasing to WA'. In other words, the source SP as the emitter of the p-n-p transistor Q1 is formed separately from the well region WL in the amount form forming the drain DP and the gate GP. Thus, the current amplification factor hFE of the p-n-p transistor Q1 for sharing the latchup operation can be largely reduced, thereby preventing the latchup.
