Title: Dc power feeding system
Inventor: KUWATA YUTAKA
IPC: G05F1/67
Filed: 1992-06-30
Abstract: PURPOSE:To control the output of a DC power generating device to maximum output electric power at all times by varying by varying the output voltage of the DC power unit of another system which feeds electric power to a load exceeding the capacity of the DC power generating device. CONSTITUTION:When the output electric power P1 of the DC power generating device increases above set electric power, an output voltage detection signal S2 becomes larger than a set electric power signal S3 and the signal S4 of a differential operational amplifier 11 increases. Consequently, the duty ratio of the output pulse width of a pulse width converter 13 becomes large and the output voltage V2 and output electric power P2 of a DC power unit 5 increase through a driving circuit 14. Consequently, the output electric power P1 of the DC power generating device 1 decreases. When the output electric power P1 of the DC power generating device decreases below the set electric power, the reverse phenomenon is caused. The output electric power P of the DC power generating device 1 becomes equal to the set electric power at all times.

Title: Ink jet head
Inventor: ABE TOMOAKI
IPC: B41J2/055
Filed: 1988-07-11
Abstract: PURPOSE:To enhance frequency response and emission stability without damaging the emission speed and amount of an ink droplet by arranging a fluid distribution element to the gap between a nozzle formed substrate and a pressure generating member. CONSTITUTION:The pressure of the ink present in the gap between a nozzle formed substrate 11 and a pressure generating member 18 is raised by displacing the pressure generating member 18 by the application of voltage and ink droplets are allowed to fly from a large number of the nozzles 20 provided to the nozzle formed substrate to form a desired ink image on a medium such as recording paper. At this time, a fluid distribution element 13 is arranged to said gap so as to set a direction allowing the ink to flow in the nozzles to a forward direction. As a result, the ink is confined in said gap by the distribution effect of the distribution element at the emitting time of the ink and the pressure of a nozzle inlet opening part 12 rises to support the emission of the ink. Further, the pressure generating member is returned after the emission of the ink and the ink passes through the fluid distribution element 13 when the gap dimension becomes large to be supplied to the nozzles. Therefore, frequency response and emission stability are enhanced.

Abstract: PURPOSE:To efficiently support an ECA(Extended Contingent Allegiance) function by adding an ECA exclusive circuit, and charging only a processing to an initiator at the time error generation among ECA functions by a communication program. CONSTITUTION:An ECA exclusive circuit 141 is added, and a part of a communication program 19d is modified.

Filed: 1986-07-25
Abstract: PURPOSE:To enable an accurate air quantity detection even at the time of exhaust gas recirculation by calculating an intake air quantity on the basis of a throttle valve opening and an engine speed, and correcting this calculated air quantity in accordance with the open/close conditions of an EGR valve. CONSTITUTION:Since an air flow rate QH is calculated on the basis of a throttle valve opening alpha and an engine speed N, an accurate intake air quantity of an inter nal combustion engine can be detected without being influenced by an intake pulsation. Further, since it is so arranged that the value of air flow rate QH is corrected by obtaining the influence due to the ON/OFF of exhaust gas recirculation from a plurality of tables corresponding to the open/close conditions of an EGR valve (exhaust gas recirculation valve) 5, a correct air flow rate value can be obtained even at the time when an exhaust gas recirculation is carried out. Accordingly, by calculating a fuel injection quantity on the basis of the air flow rate thus detected, a fuel injection control corresponding to the air flow rate can be carried out even at the time of acceleration, deceleration, further exhaust gas recirculation, and a proper air-fuel ratio can be always maintained.
