Title: Fuel injection system for diesel engine
Inventor: AIYOSHIZAWA EIJI
IPC: F02M45/00
Filed: 1990-02-27
Abstract: PURPOSE:To keep off any variation in an injection rate at each cylinder by calculating a voltage compensation value for a piezoelectric actuator so as to accord the injection pulse width of an injection nozzle with a requisite value by cylinders in an idle stable state, and on the basis of this compensation value, varying an initial lifting clearance of a nozzle needle. CONSTITUTION:An idle stable state judging means 103 judges it as a stable state if a difference between target idling speed and actual idling speed is less than the setting value by cylinders. An injection pulse width detecting means 104 inputs a signal of an on-off timing sensor, operating the extent of actual injection pulse width, and it determines a request injection pulse width at time of idling in common with all cylinders according to an engine cooling water temperature. The request injection pulse width and the actual injection pulse width are calculated by a voltage compensation value calculating means 105, finding a voltage compensation value. This compensation value is added to a reference supply voltage in common with each cylinder by a feed voltage determining means 106, thereby determining the supply voltage for a piezoelectric actuator 102. In consequence, an initial lifting clearance approximate to the request value is set even to any cylinder, thus any variation in an injection rate at each cylinder is checked.

Patent JP-S60189985-A (JP)
Title: Buried type semiconductor laser
Inventor: KAWANO HIDEO
IPC: H01S5/00
Filed: 1984-03-12
Abstract: PURPOSE:To obtain the titled device excellent in reproducibility and reliability which oscillates by low threshold current and with high efficiency, can yield large photo output by basic transverse mode oscillation, and can be easily manufactured, by a method wherein the neighborhood of the reflection plane is filled with a semiconductor layer having a larger forbidden band width than an active layer. CONSTITUTION:Since a photo waveguide layer 8 of high refractive index sandwiched by a P type buried layer 2 and an N type buried layer 3 is present in the neighborhood of the reflection plane, light advances by convergence to the photo waveguide layer 8. The neighborhood of both end surfaces serving as the photo reflection plane forms a non excited region, and the oscillated light oscillates by penetration through a layer of larger forbidden band width, therefore, light is not absorbed in the neighborhood of the reflection plane, and optical damage is difficult to generate. Further, because of the presence of the N type photo waveguide layer 8 adjacent to the active layer 9 and of a P type buried layer 14 formed in a buried region horizontal to the N type layer 8, the difference in refractive index in the horizontal direction can be reduced. Besides, the buried layer 3 acting as a current blocking layer is continuous to the photo waveguide layer 8 only at the part of constriction 13 approx. 0.3mum wide, therefore, leakage current is difficult to flow and the current is injected into the active region effectively. This enables high photo output oscillation at low threshold value and with high efficiency.

Title: Stabilizing filter for feedback control system
Inventor: MORII SHIGEKI
IPC: G05B11/36
Filed: 1987-03-02
Abstract: PURPOSE:To realize the compensation of phase to a natural oscillation frequency to be stabilized by a defining the signal obtained by subtracting a control signal passed through a BPF from a control signal passed through a notch filter as a feedback signal. CONSTITUTION:An input signal is branched into two parts and supplied to a notch filter 1 having its center frequency approximate to the natural oscillation frequency of a mechanical system and also to a BPF 2. A subtractor 3 subtracts the output of the BPF 2 from the output of the filter 1 and the output of the subtractor 3 is outputted as a feedback signal. In such a constitution, the signal having a natural oscillation frequency component which unstabilizes the natural oscillation frequency of the mechanical system passes through the BPF 2 only and is fed back as a stabilized signal with its polarity inverted by subtraction. While other components of said signal pass through the filter 1 only and are fed back as they are. Thus the compensation of phase is possible only with the natural oscillation frequency to be stabilized.
