Abstract: PURPOSE:To cope with an abnormality in the early stage and to prevent a data from being carried away uselessly between terminals, by monitoring an aliveness or death confirming signal to be received periodically from a processor on the side of processors whose life or death is confirmed. CONSTITUTION:A processor 120 and 130 contained in a distributed processing system 100 monitor an aliveness or death confirming signal to be received from a processor aliveness or death managing processor 110 at every prescribed time, and become a dead state for themselves, in case said signal is not received for a prescribed time. In case the processor 120 goes to an abnormal state, the processor aliveness or death managing processor 110 determines that the processor 120 is abnormal, by means of the repeated aliveness or death confirming signals, and regards the processor 120 as dead in the resumption of the operation of the system 100. During such a time the processor 130 which is connected to the processor 120 by a bus 150 cannot receive an aliveness or death confirming signal from the processor alivness or death managing processor 110, informs a terminal 300 of death of the processor through a bus 200, goes to a dead state itself, and goes to a state of waiting for a resumtion instruction from the processor alivneszs or death managing processor 110.

IPC: F02D41/10
Filed: 1985-03-05
Abstract: PURPOSE:To precisely control a fluctuation in an air-fuel ratio during acceleration, by a method wherein a maximum pulse width during acceleration of an engine is set by means of the number of revolutions of an engine and the opening of a throttle. CONSTITUTION:An engine control unit 24 receives an output from a vane type suction amount sensor 17, a fuel injection valve 9 is driven through computation of a fuel injection pulse having a pulse width responding to a suction air amount, and a given amount of fuel is fed to an engine 1. In which case, the number of revolutions of an engine is detected by a number of revolutions sensor 20, and the opening of a throttle valve 11 is detected by a throttle sensor 19. By means of the two signals, the maximum pulse width of a fuel injection pulse is determined, and a fuel injection pulse to a fuel injection 9 is limited to lower than the maximum pulse width during acceleration of the engine 1. This precisely controls a fluctuation in an air-fuel ratio due to the overshoot phenomenon of the suction amount sensor 17.

Filed: 1981-03-25
Abstract: PURPOSE:To make a combination of specified phosphors and to solve the problem of  erroneous visual recognition by arranging the characteristics of response build-up and  remaining light of the phosphors. CONSTITUTION:A phosphor P-22 (red), which displays a spot of high voltage luminous  light of green at a pulse signal shown at the upper level and is quick in response build- up with remaining light time being short when it is moved as shown by an arrow at  the lower level, changes its amount of luminous light shown by an actual line, while a phosphor P-1 (green), which shows medium response build-up with remaining light time  being moderate, changes as shown by a dotted line. Since the separated colors of the  remaining light, or red in the forward direction and green in the backward direction of the transfer, can be confirmed, only a combination of P-22 (red) and the phosphor P-22  (green) which is quick in response build-up with remaining light time being short is  suitable for matching the characteristics of the changes of light quantity and thus erroneous visual recognition can be liquidated. For the particularization of the selection  of a luminous phosphor in single color, the luminous phosphor in single color as the  one proposed is processed so that it is changed into a desired beam penetration type  phosphor and then those with remaining light characteristics arranged in order under the average luminant conditions (voltage, current) and adopted.

Title: Circuit for processing negative signal
Inventor: MAENO YOSHIHIKO
IPC: G01M15/00
Filed: 1985-03-05
Abstract: PURPOSE:To enhance responsive performance of an eigine by installing a time constant variable type negative pressure filter for eliminating ripple elements and a throttle alteration detector that temporarily reduces the time constant of the filter upon rapid changes of the throttle opening. CONSTITUTION:A differential circuit 42 issues differential output corresponding to the first transition of throttle opening signals while a differential circuit 44 issues differential output corresponding to last transition of the signals. The output becomes input to a buffer circuit 41 through a diode ore circuit 45. When input surpasses threshold value, in other words, the throttle opening changed rapidly, output reaches the H level, with an analog SW turning on. As a result, R1 and R2 are connected in parallel, resistance value declines, time constant diminishes and transitional responsive performance improves. When output rests with the L level, namely, changes of throttle opening are moderate, resistor R1 of a filter 1 is not used, the overall resistance value becomes big, time constant is also large and the ripple elimination rate proves high. Thus, responsive performance of the engine can be enhanced.

Abstract: PURPOSE:To prevent collision between a plurality of carriers, running on a running track, by providing a carrier stopping means for stopping the carrier, which receives a photo signal when a preceding carrier is positioned on a corner track, on a linear running track in the vicinity of the inlet of the corner track. CONSTITUTION:When a light shield plate 63 arranged in the intermediate position of a corner track 1a is detected by means of a pair of position sensors 65 and 66, a carrier 23B is stopped approximately at the intermediate point of the corner track 1a. In this case, when the front position sensor 65 is turned ON but the rear position sensor 66 is not turned ON, the carrier 23B is caused to effect micromovement in a running direction until both position sensors 65 and 66 are turned ON, and inching control is carried out. Thus, when both position sensors 65 and 66 are turned ON, the carrier 23B is stopped at a set position and control of the stop of the carrier 23B is completed.

Title: Fuel supply device for internal combustion engine
Inventor: ODA HIDEYUKI
IPC: F15D1/08
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To reconcile an improvement in fuel consumption and an improvement in engine output by providing a control pressure variable mechanism to vary fuel pressure adjusted by a high pressure control means according to a delivery flow rate of a high pressure fuel pump. SOLUTION: An orifice 43 whose flowing resistance increases according to flow speed is arranged in an inlet side passage part of a valve seat 37 as a control pressure variable mechanism. When engine speed of an engine increases, a delivery flow rate of a high pressure fuel pump increases, and this orifice 43 acts as flowing resistance. That is, when rotating speed of the engine exceeds a prescribed value, fuel pressure increases according to an increase in engine speed of the engine. Therefore, when engine speed of the engine is low, fuel pressure suitable for improving fuel consumption by partial combustive operation is set, and when engine speed of the engine is high, fuel pressure sufficient for improving engine output by fully opening torque is set.
