Title: Semiconductor device
Inventor: TAKASE MASASHI
IPC: H03K19/086
Filed: 1988-03-11
Abstract: PURPOSE:To manufacture a structure subjected to no change in output level even if the gate working factor is changed by a method wherein an emitter is divided into multiple emitter regions (layers) 23 while the emitter regions are connected to one another with the increase in the gate working factor of ECL(emitter.coupled.logic) gate array. CONSTITUTION:Multiple emitter of an output transistor are independently provided in a base layer 22 and when a collector electrode 11, a base electrode 12, an emitter 13 and a wiring are formed, the numbers of emitter regions required for correcting the output level are decided by the gate working factor to wire the emitter regions of the decided numbers but the remaining emitter regions are not wired. That is, when the power supply current Ip running in a paracitic resistor is high due to the high gate working factor, the fall in voltage of the parasitic resistor is so heavy that all of the emitter regions E1.E2.E3 are wired and connected to make the emitter area of output transistor larger and smaller and when the gate working factor is lower, E1 only out of the emitter regions E1.E2.E3 is wired. Consequently, the change in output level can be restricted by changing the emitter area of the output transistor.

Title: Carburetor having piston type acceleration pump
Inventor: IIDA KAZUMI
IPC: F02M7/08
Filed: 1982-04-12
Abstract: PURPOSE:To prevent leakage of fuel into an inoperative chamber at the time of acceleration, by forming connecting passages in a piston of a carburetor having a piston type acceleration pump in the manner that said passages communicate an operation chamber with a recess formed in said piston whereto the extention of the peripheral portion of a sealing member is located. CONSTITUTION:A circumferential recess 32 is formed in a piston 19 of an acceleration pump 16 at the portion thereof located on the side of an inoperative chamber, and the outer surface of the piston 19 at the portion is covered with a sealing member 33 the extention of the peripheral portion of which is located at the recess 32. The piston 19 is formed with connecting passages 37 which extend between the recess 32 and a spring seat 40 disposed on the side of an operation chamber 28 of the piston 19. With such an arrangement, when a throttle valve is operated for acceleration, pressurized fuel is delivered into the recess 32 via the connecting passages 37 formed in the piston 37 and forces the seal member 33 onto the surface of the cylinder wall. Since the clearance between the seal member 33 and a cylinder 18 is removed by the function of dynamic pressure of fuel acted effectively in the recess 32, it is enabled to prevent leakage of fuel into the work chamber 28 in a reliable manner.
