Abstract: PURPOSE:To prevent simultaneous turn ON of switching elements and to prevent overcurrent by constituting a voltage doubler rectifier circuit through a conduction element immediately after throw-in of power supply. CONSTITUTION:A relay is not excited for a predetermined time before and after throw-in of power supply thus bringing a bilateral switch SW2 into ON state.

Filed: 1988-05-06
Abstract: PURPOSE:To inject a necessary amount without a waste, by a method wherein a plunger is coupled to the pressure cone apex of a lever, and the stroke of the plunger is controlled by changing a distance between a point of force, a fulcrum, and a pressure cone apex. CONSTITUTION:A lever 1 performs rocking movement around a pin 10 serving as a fulcrum through rotation of an eccentric pin 5, a plunger 4 formed integrally with a bearing 3 of a shaft 2 at a pressure cone apex is reciprocated, and the stroke of the movement is changed according to the position of the pin 10.

As noted above, movement of the position of the pin 10 enables the change of the stroke of the plunger 4 to change an injection amount. Fuel pressurized by the plunger 4 flows through a delivery valve 8 and a pipe 7 to an automatic injection valve, and is injected through a nozzle.

Filed: 1984-05-30
Abstract: PURPOSE:To prevent erroneous sorting due to malfunction by sending a signal indicating the capacity of a sorter from the sorter to the image forming device, and limiting image formation conditions with the signal. CONSTITUTION:¦A sorter control part 56 sends sorter mode signals S-MODE0 and S-MODE1 which indicate the operation mode of the sorter and the permissible number of bins to a copying machine control part 51. The signal S-MODE0 and S-MODE1 have different meanings according to the on-off state of a signal S-INT; when the S-INT is off, they show the operation mode of the sorter and the copying machine control part 51 changes and displays control programs with those signals. When the signal S-INT is on, on the other hand, the sorter is initialized by the on-to-off switching of the signal S-INT, so the operation mode of the sorter needs not be known. For the purpose, when the signal S-INT is on, the number of usable bins of the sorter is sent with the signals S-MODE0 and S-MODE1.
