Abstract: PURPOSE:To size an inner diameter together with outer diameter of an annular gear into highly complete circularity by correcting the one side of the inner diameter side or the outer diameter side in the sintered body-made annular gear under opening condition of the other side successively through a core rod and a die. CONSTITUTION:The metallic mold for sizing is constituted of the core rod 10 corresponding to the inner diameter size in the product, the die 20 corresponding to the outer diameter size in the product, a lower punch 30 and an upper punch 40. Further, intermediate part of the above core rod 10 is formed to small diameter as inside diameter face unrestricting part 11, and upper part of the die 20 is formed to large diameter as outside diameter face unrestricting part 21, and both unrestricting parts 11, 21 are set to mutually shifted positions. In this metallic mold, the sintered body- made gear A having teeth at the inside diameter side or the outside diameter side, is set. This gear A is pushed to upper part of the core rod 10 with the upper punch 40 to correct only the inside diameter face under unrestricting condition of the outside diameter face. Successively, this is further pressurized to correct the outside diameter face with the die 20 under unrestricting condition of the inside diameter face. Finally, this is inserted into space between the lower punch 30 to finish the upper and lower faces and the sizing of gear A is completed.

IPC: F02D41/04
Filed: 1986-04-09
Abstract: PURPOSE:To diminish pulsation generated at the time of idling an engine by adding specified times to each other to obtain a fuel injection pulse time in a condition that an idle switch is on and at less than a defined engine speed. CONSTITUTION:Air which is sucked into an engine is measured by an air flow quantity sensor 1 and the measured value is taken into a control unit 2. In the unit 2, a feeding fuel quantity is calculated and pulses corresponding to this fuel quantity are outputted to an injector 3. In this case, a fuel injection pulse time with an idle switch on and at less than a defined engine speed, is defined as a time in which a pulse time of N0 times the this-time fuel injection pulse time which indicates a fuel feeding quantity obtained from the engine speed and intake air quantity, is added to a pulse time of N1 (=1-N0) times the last-time fuel injection pulse time. Thereby, pulsation which is generated at the time of idling can be diminished.
