Title: Diaphragm type fuel pressure control valve
Inventor: ABO MATSUHARU
IPC: F02M69/00
Filed: 1987-09-30
Abstract: PURPOSE:To eliminate ununiformed valve opening and prevent any damage to the function of pressure regulation even if a holding body is separated from a movable valve body by making a valve body and the movable valve body of magnetic materials with mutually opposite magnetic poles so as to open a valve seat by the effect of the resiliency of the magnetic force. CONSTITUTION:A valve body constituting a valve seat member 8 and a movable valve body 9 are made of magnetic materials with mutually opposite poles. As a result, when fuel quantity flowing out to an outlet passage 7 is small, the moving quantity of the movable valve body 9 is also small, and thereat, resiliency due to the magnetic force of the magnetic body is inversely proportional to the moving quantity of the movable valve body 9 so that, except for the time of entirely closing the valve, the valve seat member 8 and the movable valve body 9 face to each other in a non-contact state despite the small moving quantity, so as to secure fluid passage and obtain the stable function of pressure regulation. In addition, even if a holder 10 is separated from the movable valve body 9 during the operation, the bottom surface of a supporting body 15 acts as an auxiliary valve seat and the holding plate 11 of a diaphragm 3 acts as a valve cap, thereby preventing any damage to the function of pressure regulation for fuel.

Abstract: PURPOSE:To realize a transmission circuit of a signal having a short signal amplitude with one power source and to easily raise the transmission frequency even in the case of a large load capacity on a transmission line by driving the signal transmission line, which is connected to the same supply voltage as a module through a terminal resistance, with a short amplitude near to the supply voltage. CONSTITUTION:A digital data processing system is provided with two busses BUS-A and BUS-B which connect a processor unit PU and memory units MU0 to MUn to each other. Each of these busses consists of plural pairs of complementary signal lines and transmits the output signal of the unit PU to units MU0 to MUn or transmits output signals of units MU0 to MUn to the unit PU. The amplitude of the signal transmitted through busses is so limited that it is 1/(n) or less of the absolute value of the supply voltage ((n) is 10 or several), and the AC power consumption of each bus is considerably reduced. Since a maximum operating frequency of the transmission signal can be raised, the power consumption of the system is reduced and the operation speed is increased.
