Title: Fuel injector of engine
Inventor: ODA HIROYUKI
IPC: F02D41/00
Filed: 1983-12-07
Abstract: PURPOSE:To prevent blow-by of injected fuel in a system wherein the fuel injection completion timing of a fuel injection valve disposed in an intake port is set to the proximity of an intake valve closing timing by compensating the fuel injection completion timing to a slower timing in the operating range where much fuel is injected. CONSTITUTION:In operation of an engine, CPU15 reads and stores each signal of a pressure sensor 8, a water temperature sensor 9, a crank angle sensor 10 and an ignitionn switch 11. If the operation is not made for engine start, CPU computes a reference injection quantity from an engine rpm and a suction negative pressure, and compensates the reference injection quantity according to the temperature of cooling water so as to redetermine the reference injection quantity as an actual injection quantity. From the actual fuel injection quantity an injection angle theta is determined and from both suction valve fully-closed timing and specified-injection completion timing compensatory quantity, an injection completion timing thetaic is determined so as to determine whether theta is larger than the crank angle made between thetaic and an exhaust valve fully-closed timing, or not. If determination of YES is obtained, an injection start timing thetaio according to the injection angle theta is determined based on the timing thetaic, so as to control a fuel injection valve 6.

Title: Loop control system
Inventor: TSUKADA KAZUMASA
IPC: H04L12/437
Filed: 1983-12-09
Abstract: PURPOSE:To detect abnormality easily by connecting one terminal control part and plural node parts to a pair of optical communication loop circuits reversely connected to each other, and when abnormality is generated on the way, looping back a signal together with an inherent node name. CONSTITUTION:One terminal control part LCS200 is connected to a pair of optical signal tranmitting lines A, B reversely connected to each other like a loop through plural node parts NS100 (only one is shown in the figure). When there is no abnormality in the circuit, a signal from a sending terminal a' is returned to a terminal b' of the LCS through terminals c, d of the node parts 100, an LCS name is assigned to the signal and the LCS name assigned signal is looped back from a terminal d' and returned to a terminal c' through the node 100. If a fault is generated on a position shown by a cross (x), the signal is not reached a terminal (b) of the node 100 and an abnormality detecting circuit (not shown in the figure) in the node 100 detects the abnormality, assignes the code of the node 100 to the signal and the signal is looped back by switching a terminal (c) to a terminal (a). The loop back is detected by the terminal c' of the LCS, so that a fault section can be easily informed.

IPC: B23K11/00
Filed: 1988-09-16
Abstract: PURPOSE:To provide a light-weighted push rod having excellent strength and wear resistance and a high dimensional accuracy at a low cost by bonding steel balls of ball bearings to the both ends of a thin stainless steel pipe by projection welding. CONSTITUTION:A push rod main body 1 is formed by cutting a thin stainless steel pipe having an excellent strength into a determined length.
