Title: Method and apparatus for recording image
Inventor: ITO SHINICHI
IPC: B41M5/337
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To stably optimally erase by driving a heater at least by three pulses for color developing within one pixel recording period of an image to be recorded, and driving it at least by two pulses except its second pulse for color erasing. SOLUTION: Three pulses are continuously applied to a color developing pixel. A heating resistor temperature of a thermal head 13 is slightly lowered while a pulse is not applied and again raised. This change is repeated, it is substantially continuously raised. And arrived at a color developing temperature range in a short time. Meanwhile, at a color erasing pixel, the second pulse is not applied, it is lowered after the first pulse is applied and again raised by application of the third pulse, and lowered. At this time, it is once raised at a lower color erasing temperature than the color developing temperature and lowered.  But, since it is again raised by the third pulse before it is lowered to an insensitive temperature range, it is held at the color erasing temperature for a longer time in the same period as that of the color developing heating, and better color erased as compared with that of the case of the continuous application.

Filed: 1979-06-01
Abstract: PURPOSE:To improve the moisture resistance of the semiconductor device by forming inoperative structure for water content and ion at the base and collector electrodes to which high electric field is applied particularly to the electrodes on the  surface of the substrate. CONSTITUTION:Base and emitter regions 2 and 3 are formed on an Si substrate 1, openings are thereafter perforated at the insulating film, and base, emitter and collector equi-potential electrodes 5, 6 and 4 are formed. Then, the electrodes 4 and 5 are coated with Au7. As a result, since the voltage between the base and the collector becomes at maximum electric field on the surface of the shortest Au7 between the electrodes, even if various ions are adhered to the film 7 in the state that high temperature, and moisture and reverse bias exist, the film 7 is chemically stable and transmits no ion. Accordingly, it can prevent the production of chemical compound of the electrodes 5, 6. In this manner, there can be obtained a transistor having high moisture resistance.

Abstract: PURPOSE:To attain an appropriate photographing corresponding to the luminance of an object, by driving and controlling the readout driving of a solid-state image pickup element by switching it to a frame driving and a field driving, corresponding to the luminance of the object obtained by a photometric means. CONSTITUTION:The readout driving of a charge coupled device 26 is selected by a CCD driving selection signal 29 outputted from a control circuit 20 to a synchronizing signal generation circuit 18 on the basis of the luminous quantities of a photometric element 16, and a driving pulse is sent out through a control line 30, and a video signal based on an electric charge accumulated on an image pickup plane 28 is inputted to a recording signal processing circuit 34 as a series signal. The signal frequency- modulates the video signal by a ruster scan by reacting to driving signals including a vertical and a horizontal synchronizing signals from the synchronizing signal generation circuit 18, a phase pulse PG, and furthermore, a recording indicating signal from the control circuit 20, and outputs it as a modulation video signal of prescribed format. Since one photodiode corresponds to one picture element in the frame driving, the vertical resolution of an object image becomes maximum. Thus, since signal charges at the photoreceiving parts of plural lines are read out simultaneously in the field driving, photoreceiving sensitivity in the field driving can be improved compared with in the frame driving.

Title: Distributor type fuel injection pump for diesel engine
Inventor: ETOU YUKIHIRO
IPC: F02D41/10
Filed: 1980-05-27
Abstract: PURPOSE: To prevent the abrupt injection timing advance at the time of acceleration by a method wherein an advance control mechanism is provided between a pump chamber and a timer cylinder.  
     CONSTITUTION: At the time of acceleration, the oil pressure within the pump chamber rises abruptly and a solenoid 34 is excited, in response to the acceleration signal produced by the detection of the abrupt pressure rise indicating the acceleration, to position a valve spool 33 rightwards. Due to the rightward displacement of the valve spool 33, a fuel oil passage 40 is shut and the oil pressure within an oil pressure chamber 20 of the timer cylinder 18 is maintained at the fuel oil pressure held at the time of shut, thus resulting in causing no injection timing advance. With the lapse of time, the oil pressure within the oil pressure chamber 20 rises gradully by means of the fuel oil passing through an orifice 41 to advance the timing slowly. When the acceleration ends and the excitation of the solenoid 34 is stopped, the valve spool 33 is returned leftwards and the pump chamber and the oil pressure chamber 20 are communicated through the fuel oil passage 40 to make the subsequet setting of injection timing in response to the oil pressure within the pump chamber possible.
