Title: Malfunction preventing circuit for opposing side monitoring relay in trunk
Inventor: CHIKIRA HIROSHI
IPC: H04Q3/42
Filed: 1980-07-14
Abstract: PURPOSE:To prevent malfunction due to momentary interruption of signal or momentary operation of signal, by giving slow operation or restoration to a relay receiving a signal from a carrying device. CONSTITUTION:When a main trunk is started and a relay B is activated, the preceding relays are started via a carrying device with a circuit of ground-contact m<2>-contact ra<2>-contact b<1>-terminal SS-. A carrier line is malfunctioned by noise before the response of called party and a response signal is momentarily outputted, then no reponse is made unless the output continues for a given time or more by giving a slow operation characteristic to a relay R. When a called party responds and charging pulse is transferred from the post device via carrier line, even if the part on the way is momentarily interrupted due to noise, it is not received as the transfer or charging pulse unless sure signal transfer is received more than a given time by giving a slow restoration characteristic to the relay R.

IPC: F02B47/02
Filed: 1992-04-15
Abstract: PURPOSE:To decrease a fuel injection amount in accordance with decreasing a supply amount of water so as to decrease concentration of exhaust graphite by detecting the concentration of exhaust graphite by a smoke sensor formed of a light source and an optical sensor, thus to control a fuel injection pump when a detection value is a fixed value or more. CONSTITUTION:In a fuel injection pump 111, fuel supplied from a fuel tank 21 by a fuel supply pump 22 and a fuel injection pump 23 and water supplied from a water tank 28 through a solenoid valve 31 by a water supply pump 29 are respectively injected into a cylinder of an internal combustion engine. Now when a water supply system is in improper operation, a fuel injection amount is relatively increased by the amount of decreasing a supply amount of water, and concentration of exhaust graphite is rapidly increased. Here by a smoke sensor formed of a light source 35 and an optical sensor 36, graphite concentration in an exhaust pipe 41 is detected. When a detection value is increased to a fixed value or more, water supplied to the fuel injection valve 111 is decided insufficient, and thus by a controller 33, a rack position of the fuel injection pump 23 is properly controlled.
