IPC: F02M69/00
Filed: 1995-05-17
Abstract: PURPOSE: To stabilize engine revolutions at an early stage of hot restarting by forming an inner collar out of a press fit section and a down projection section which is projected downward from the press fit section via a locking step section, and concurrently disposing the aforesaid down projection section in such a way as to be projected in the inside of a planger spring housing path. CONSTITUTION: When an engine is in operation, fuel is injected out of a measuring injection hole 12C by the excitation of a coil 9 based on an injection signal after fuel has passed through a strainer fit-in path 3B, the passage 20D of an inner collar 20, a spring housing path 3C, a gap over the outer circumferential surface of a planger 15, and a gap between a needle valve guide hole 12B and a needle valve 14. In this case, a down projection section 20C is projected downward out of the lower end of the press fit section 20A of the inner collar 20, the down projection section 20C is projected in the inside of the spring housing path 3C, and the volume of the inside of the spring housing path 3C is thereby reduced.  By this constitution, the volume of accumulated fuel at the upstream side of a seat ring 12A is made small, and at the time of hot restarting, fuel can thereby be brought into a gas-liquid mixed condition in a short time.

IPC: H02P25/08
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent a switching error caused by the noise of a detected current signal, by causing a filtering means to eliminate a false signal by high-frequency noise having a period of a set time or less from a switching signal, and to generate a switching signal with corresponds to the detected current value correctly. SOLUTION: A filtering means of an output judging circuit 17 eliminates a false signal generated by high-frequency noise having a period equal to or shorter than a comparatively long set time at the time of hard chopping, from a switching signal to be obtained by comparing a current value Vs6 detected by a load current detector 2 with target current values Vr1, Vr2 of a current waveform generating circuit 15. Besides, at the time of soft chopping, it generates a switching signal which does not have false signals by high-frequency noise having periods equal to or shorter than a comparatively short set time. Consequently, it becomes possible to prevent a switching error caused by high-frequency noise.

Abstract: PURPOSE:To attain amplitude control without amplitude distortion even when a signal amplitude level is increased by providing a current control circuit supplying a control current in response to the signal amplitude to a base of each transistor (TR) pair so as to control each TR pair. CONSTITUTION:A current control circuit 36 is provided with a current mirror circuit 53 comprising TRs 42, 44, 46 and resistors 48, 50, 52 to extract a control current Ic flowing to a TR 38 in response to the TR pairs 20A, 20B. In this case, since the emitter area of the TR 44 is selected to be twice that of the TRs 42, 46, a control current 2Ic being twice the current Ic flows to the TR 44 and the current Ic flows to the TR 46. When the amplitude of an input signal Vi is large, the currents Ic, 2Ic are increased and when the amplitude is small, the currents are decreased, then the resistance of the TR pair 20A, 20B is con trolled in response to the amplitude level of an output signal V0. As a result, when the amplitude level of the signal V0 is large, the amplitude of the signal Vi is suppressed and when small, the suppressing state is relaxed, then the amplitude is controlled by the attenuation in response to the amplitude of the signal V0.
