Title: Mechanical control device for supercharger of internal combustion engine with auto-drive-device for vehicle
Inventor: YOSHIOKA MAMORU
IPC: F02B33/00
Filed: 1986-07-15
Abstract: PURPOSE:To restrict the occurrence of a slip even under the circumferential condition in which a slip easily occurs, by selectively operating a supercharger, based on a comparison between the load threshold value, which is determined in accordance with the slip condition, and the actually measured value. CONSTITUTION:A slip-condition-discriminating-means 4 discriminates the circumferential condition, under which a vehicle is subject to a slip, from that in which a slip does not occurs. For example, the means 4 discriminates rainy weather from fine weather. When it is rainy weather, in which a vehicle is apt to slip, the ratio of the intake-air-flow to the engine revolving speed, or Q/NE, is set a at low threshold value of 0.4(l/rev), while, in the normal condition, the ratio is set at a high threshold value of 0.5(l/rev). A supercharger driving means 6 compares this load threshold value with the actually measured value, which is detected by a load detecting means 3, to drive or stop a supercharger 2.

Title: Switch circuit
Inventor: NAKASHIMA TADASHI
IPC: H03K17/00
Filed: 1979-12-18
Abstract: PURPOSE:To make effective the switch finally depressed only, by inhibiting the input of other switches, when closing one switch. CONSTITUTION:When the switch Sd in a circuit 3-2 is closed, the input of an inverter 4 and an AND gate 5 is low. Since the output of the inverter 4 is high, the output of an NAND gate 6 is energized low. At this time point, since the output of an NOR gate 7 is energized high, a monostable multivibrator 8 is triggered and a positive pulse is fed to a clock input T of a flip-flop 9 to set the flip-flop 9 of the circuit 3-2. In this case, since a low input is present at the data input D, the output of the flip-flop 9 is low. By depressing the switch Sd, the input inhibiting signal is fed to the lower rank NAND gate 6 and NOR gate 7 from the upper rank.
