Title: Method for determining injection quantity at start of internal-combustion engine
Inventor: MASUI TAKATOSHI
IPC: F02D41/00
Filed: 1984-02-16
Abstract: PURPOSE:To prevent an engine from being supplied with overrich fuel when the engine is started by determining the quantity of fuel which is to be supplied when the engine is started, according to a lapse of time from the starting point of the engine run. CONSTITUTION:An engine starting point is detected at a step S1. If the engine starting point is detected, a reference fuel quantity which is determined on the basis of the engine running conditions including an engine rpm and an intake air quantity is multiplied by a value having a tendency that the value is increased with time passed from the engine starting point, at a step S2 so as to derive the starting compensated fuel quantity. At a step S3 the quantity of fuel to be supplied at the starting point is found by adding the starting compensated fuel quantity to the reference supply fuel quantity. The engine may be thereby prevented from being supplied with overrich air fuel mixture.

Title: Gate pump
Inventor: HARADA ICHIRO
IPC: F04D13/08
Filed: 1990-02-09
Abstract: PURPOSE:To prevent the occurrence of swirl flow by a method in which a swirl flow-preventing plate is provided in almost parallel with water surface below the lowest water level of operation in a pump set in the gate. CONSTITUTION:A pump 1 is attached to a gate 2, and a porous plate (screen) 7 with small hole pitches near water surface, having a swirl flow-preventing plate 6, is also attached. By operating the pump 1, the inside water level is lowered as water drain proceeds to cause downward flow near the pump 1, where harmful air suction vortex occurs by intensifying the downward flow. The downward flow is interrupted by means of the plates 6 and 7 to enable the pump in low water level to be operated, and also by varying the pitches and sizes of the holes in the plate 7, resistance near water surface is changed. The pump can thus be operated to lower operating water levels without varying the structure.
