Title: Fuel injection quantity control device for internal combustion engine
Inventor: OTSUKA IKU
IPC: F02D41/10
Filed: 1990-02-02
Abstract: PURPOSE:To prevent acceleration shock always stably by judging the nonsynchronous injection timing in the intake stroke of each cylinder on the basis of the crank position of an internal combustion engine at the acceleration starting time of the internal combustion engine so as to correct the nonsynchronous injection quantity. CONSTITUTION:A fuel injection valve M2 in each cylinder of an internal combustion engine M1 is controlled by a means M5 so as to perform synchronous and nonsynchronous injection in each cylinder at the acceleration starting time judged by a means M4 on the basis of the operating state detected by a means M3. In such a device, the crank position of the internal combustion engine M1 is detected by a means M6. Also at the acceleration starting time, the nonsynchronous injection timing in the intake stroke of each cylinder is judged by a means M7 on the basis of the crank position. At this nonsynchronous injection timing, the nonsynchronous injection quantity from the means M2 controlled by a means M5 is corrected by a means M8. Acceleration shock caused by the nonsynchronous injection can be therefore performed always stably.

Filed: 1991-02-19
Abstract: PURPOSE:To automatically decide the traveling route of a vehicle by selecting the route of the lowest cost by setting a cost expressed by weighing a distance between the respective intersection points of a mesh to the intervals of them to the traveling possible range of a floor surface. CONSTITUTION:The mesh expressing a virtual track is put to the traveling possible range Aa, a traveling impossible range Ac already fetched is supposed to be painted out with blue, e.g. and vertical lines, lateral lines and oblique lines, which corresponds to the mesh are supposed to be substituted with red. Then, the intersection points made by the line-drawing is successively investigated. It can be known the point is within the traveling possible range Aa when the picture element is 'red' and the point is within the traveling impossible range Ac when 'red+blue'. Furthermore, the traveling possible range Aa is set, a cost is calculated by setting only points within the traveling possible range Aa (namely, the intersection point of the mesh) to be objects and the sum of the cost from the starting point and the reach-in point of the traveling possible range with regard to the respective intersection points of the mesh is obtained so that the route of the lowest cost is selected.

Filed: 1988-02-05
Abstract: PURPOSE:To simplify the test of a system power supply and at the same time to improve the system reliability by checking automatically whether or not a power supply works normally for a period longer than a polling period by the system. CONSTITUTION:When a system power supply undergoes a test, an MPU 1 receives a test signal of a power supply 2 from an SVP 6 and starts a test routine after discriminating the test signal. In case no test signal is decided, a main routine is started. Then the normal polling is discontinued for a fixed period. The input signal of the power supply 2 is forcibly turned off and the time count is started via a receiver 3 at and after the OFF state of said input signal. The output of the power supply 2 is gradually turned off with the OFF of the input signal and an alarm signal is sent to the MPU 1. The MPU 1 receives the alarm signal via a receiver 5 and stops its counting action. It is decided whether the time covering the OFF of the input signal through the reception of the alarm signal is longer than the polling period or not. If so, the state of the power supply 2 is judged as normal and displayed.

Abstract: PROBLEM TO BE SOLVED: To let sucked water finish flowing out in a short period of time by a method wherein a large diameter drain outlet that serves also as an outside air intake is provided at the center of a bottom plate that has a downward slope toward the center. SOLUTION: A sliding plate 21 is water-tightly fitted in the lower part of the inside of a shell 2a of a container, and when the liquid in the container flows out and decreases, the sliding plate 21 rises to relieve a negative pressure state inside the container. Therefore, a bottom cover 31 having a raised bottom plate 35 is fitted in the lower end of the shell 2a of the container and a large diameter drain hole 38 that serves also as an outside air supply device is provided at the center of the bottom plate 35 that has a downward slope toward the center. Thereby, as the sliding plate 21 raises when the container is put on a floor and a pump is operated, the negative pressure state produced between the sliding late 21 and the bottom cover 31 is relieved by sucking outside air from the drain hole 38. Water entering a gap between the sliding plate 21 and bottom cover 31 flows along the slope and discharge outside through the drain hole 38 in a short period of time.
