IPC: H04N3/16
Filed: 1988-04-11
Abstract: PURPOSE:To obtain a vertical deflecting circuit with a small flyback period ratio at a low power loss by generating a flyback pulse with the inductance of a vertical deflecting coil and a resonance capacitor based on the electromagnetic energy of a vertical deflecting coil and executing the cut-off action for the voltage of the flyback pulse with a diode for preventing a reverse current. CONSTITUTION:The title circuit provides a diode means 4 for preventing a reverse current to prevent the reverse current at the flyback period of the positive polarity side of a vertical output push pull amplifier 3, a response capacitor means 7 and an electrostatic energy supplying means for correcting a flyback pulse. The resonance capacitor means 7 resonates with the inductance of a vertical deflecting coil 5 and generates a flyback pulse based on a vertical deflecting coil initial current immediately before the picture lower part flyback is started. The flyback pulse flows backward a vertical output circuit 4 by a diode 4 for preventing the reverse current and it is prevented that the output energy is deenergized. Thus, a vertical output circuit 4 can be operated by the same low voltage power source as that of the scanning period even during the flyback period.

Abstract: PURPOSE: To shorten the risetime and falltime of fuel injection by a method wherein the displacement of a needle at a fuel injection nozzle of a Diesel engine is controlled by controlling the pressure supplied to a needle holder, and the control of the pressure is effected by two flow-controllable valves.  
     CONSTITUTION: Compressed fuel is supplied from a fuel compressor 10 to an oil sump 21 at the fuel injection nozzle 17 and is fully charged. In this condition, a control valve 37 is throttled, while a control valve 38 is fully opened. As a result, the pressure in a chamber 29 of the needle holder 25 is rapidly lowered below the pressure of the sump 21, the needle 19 is moved upward, a nozzle hole 20 is opened and the fuel is injected. When the valves 37 and 38 are switched over to the fully opened position and the fully closed position, respectively, the pressure in the chamber 29 is rapidly increased so that the needle 19 is lowered to plug up the needle hole 20. Accordingly, the pressure change characteristics of the chamber 29 is improved, the resetime and falltime of fuel injection are shortened and the device becomes able to response to a change in 1ms or below.

Title: Solid-state image pickup device and camera using the same
Inventor: TACHIKI SHIGEYUKI
IPC: H04N5/341
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To always keep an optimum sampling phase for an AD converter by impressing a pulse from an electric charge injection part inserting a reference pulse in an area where an output pixel signal is not effective, detecting the reference pulse from a signal outputted from a signal electric charge part and executing AD conversion using a sampling pulse whose phase is dynamically adjusted on the basis of the phase delay of the reference pulse. SOLUTION: Signal electric charges for one line stored in a photoelectric conversion part 21 are transferred to a horizontal transfer part 23 by a vertical transfer part 22 at every horizontal period. The signal electric charge transferred to the horizontal transfer part 23 is horizontally transferred in the direction of a signal electric charge detecting part 24 within one horizontal period, converted into a voltage by the part 24 and adopted as the output of a solid- state image pickup device. Whenever a vertical transfer pulse is supplied to the solid-state image pickup device, an injection pulse is inputted from the electric charge injection part 25 at the top of the horizontal transfer pulse. As a result, the reference pulse can be inserted just after an output pixel signal effective part in the solid-state image pickup device output signal. The reference pulse is extracted just before inputting to the AD converter.
