Title: Atmospheric pressure detecting method of internal combustion engine
Inventor: YAMAMOTO TOSHIO
IPC: F02D45/00
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent a stall caused by erroneous detection of atmospheric pressure thereafter by detecting and renewing atmospheric pressure at that time when the stall of an internal combustion engine caused by erroneous detection of atmospheric pressure is caused. SOLUTION: An engine is started on a flatland, and afterwards, it is moved up to a highland without stopping the engine, and an engine stall is caused on the highland, and when the engine is not restarted still in its stopping condition, whether or not an engine stall is caused is judged (S1). Next, whether or not a vehicle speed sensor is normal is judged (S2). Then, whether or not vehicle speed is 0km/h is judged (S3), and whether or not it is not restarted is judged (S4). Intake pipe pressure is renewed (S5) as atmospheric pressure from a supercharging pressure signal outputted by a pressure sensor. Therefore, when the engine is restarted on the highland thereafter, since operation is perfomed on a fuel injection quantity by using atmospheric pressure detected on the highland, a stall after a restart can be prevented.

IPC: F16D25/063
Filed: 1990-02-21
Abstract: PURPOSE:To ensure the actuation of a valve ball by forming an inner circumferential side projection for ball nonslipping use, at the side of a piston oil chamber of a ball cylinder press-in hole, in a friction clamping element with a drift-on ball valve by means of a ball cylinder press-in system. CONSTITUTION:A ball cylinder 74 loosely fitted with a valve ball 73 is pressed in a ball cylinder press-in hole 72 provided with an inner circumferential side projection 71 at the side of a piston oil chamber 6. Thus, a drift-on ball valve 7 is assembled at few manhour. When pressure oil is fed to the piston oil chamber 6, the valve ball 73 moves to the right, the drift-on ball valve 7 is closed whereby a clutch is clamped. At time of clutch releasing, the pressure oil in the oil chamber 6 flows out of an oil hole 15, and a piston 5 moves to the right by dint of energizing force of a spring 11, thus clutch clamping force is released. At that time, the valve ball 73 shifts to the left with a hydraulic pressure drop in the piston oil chamber 6, and since it is constituted to prevent any slip-off with the inner circumferential side projection 71, the valve ball 73 operates without fail.

Title: Apparatus for display residual power of battery
Inventor: OKAMOTO TOYOKATSU
IPC: G01R31/36
Filed: 1990-02-20
Abstract: PURPOSE:To improve display accuracy by calculating an index indicating an accumulation amount per hour from previous discharge until present discharge and displaying an index indicating residual power obtained based on the above index. CONSTITUTION:When a charge switch SW is turned ON and charging is performed, total discharge time tD which has been written in is read out from a non-volatile memory 9. Base on the discharge time tD, an index (%) Q1 indicat ing a calculated amount of charge per unit hour is changed as Q1=Q10XtD0/tD, where Q10 is an index (%) indicating a standard amount of accumulation per unit hour in storage battery 4 and tD0 is standard time that the accumulator can be used since it was fully charged. Thus charging is performed during discharge, that is before the storage battery 4 is empty, as well as it is possible to prevent storage battery of errors due to repetition of an error caused such that charging is terminated before the storage battery is fully charged, and there occurs an error in an index (%) Q0 indicating residual amount of the storage battery due to a fluctuation in charged current.
