Title: Characteristic selector for semiconductor laser
Inventor: SASAKI YOSHIHIRO
IPC: H01L21/66
Filed: 1987-09-16
Abstract: PURPOSE:To execute measurement including wavelength selection efficiently without an optical spectrum measurement system, which has been used, by arranging an optical filter, through which only a wave range required is transmitted, in front of a photodetector and measuring injection current versus optical output characteristics. CONSTITUTION:When the oscillation wavelength of a semiconductor laser 2 is kept near 1310nm, the transmittance of an optical filter 3 (wavelength transmission characteristics 7) is 95%, approximately the greater part of light emitted from the semiconductor laser 2 reach a photodetector 4, and injection current versus optical output characteristics 11 are approximately equal to the case of no optical filter 3. When the oscillation wavelength of the semiconductor laser 2 is kept near 1295nm, the amount of light entering the photodetector 4 reaches 50% of the amount of emission of the semiconductor laser 2, thus bringing the gradient of injection current versus optical output characteristics 12 to 50% of the case of no optical filter 3. Accordingly, when a standard for selection is set previously regarding the gradient of injection current versus optical output characteristics the characteristics of the semiconductor laser including wavelength selection are selected without measuring an optical spectrum.

Title: High foaming plastic insulated wire
Inventor: OTSUKI HIDEO
IPC: C08F8/00
Filed: 1991-09-12
Abstract: PURPOSE:To decrease the diameter while increasing the foaming degree by using either only an ethylene-N vinylcarbazole copolymer or its mixture with other copolymers as the base polymer in an insulator of a high foaming plastic insulated wire. CONSTITUTION:By using either only an ethylene-N vinylcarbazole copolymer or its mixture with other copolymers as the base polymer in an insulator of a high foaming plastic insulated wire, the measure of foaming in the insulator can be sharply enhanced. In this case, the amount of N vinyl carbazole contained in the ethylene-N vinylcarbazole copolymer is preferably to be not less than 0.8mol% (4weight%), and its molecular weight ranges preferably from 25,000 to 40,000. A high density polyethylene or a straight chain low density polyethylene may be used. Since the ethylene-N vinylcarbazole copolymer has higher melt-tension and excellent high foaming capability compared with polyethylene, it can provide an insulating core of smaller diameter and higher foaming degree.

Title: Developing device
Inventor: HANEDA SATORU
IPC: G03G15/09
Filed: 1983-12-13
Abstract: PURPOSE:To obtain an image having neither fogging nor edge effect by producing a unidirectional electric field between a developer carrier and an electrode member provided closely to a photosentive body. CONSTITUTION:A developer layer which moves as shown by arrow is formed on the surface of the developer carrier 2 by a magnet 3 which rotates as shown by an arrow. Electrode members 12 and 12' provided to a developing device frame across an insulator neither contact the photosensitive body 1 nor destroy a toner image and is applied with a bias voltage from a bias power source 13; and the developer carrier 2 is also applied with a bias to establish an oscillating electric field between the electrode members 12 and 12'. Therefore, even when a two-component developer made into particulates is used, toner particles are easy to separate the developer layer in the oscillating electric field to attain sharp development without fogging nor edge effect and also scatter no developer from the gap of the photosensitive body.

Title: Thermal transfer recorder
Inventor: KANO HIROSHI
IPC: B41J2/325
Filed: 1985-10-18
Abstract: PURPOSE:To enable a recording paper to be securely disposed in a predetermined position, by simultaneously feeding an ink sheet and the recording paper to lead the recording paper accurately to a passage, and thereafter feeding only the recording paper by stopping the ink sheet. CONSTITUTION:When a recording paper 13 fed out from a roll 12 is located between feeding rollers 16 and 17 and a feeding switch is depressed, the presence of the paper is detected by a sensor 100, so that a thermal head 5 is pressed against a platen 6, and both an ink sheet 2 and the recording paper 13 are simultaneously fed in the same direction. When a sensor 101 does not detect the recording paper 13, the paper 13 passes between the head 5 and the platen 5, is then separated from the ink sheet 2 to enter a discharging passage 26. When the paper is detected by the sensor 101, the head 5 is separated from the platen 6, and only the paper 13 is fed by such an amount that is protrudes slightly from a discharging port 20a. Accordingly, the recording paper can be securely disposed in a predetermined position, and useless feeding of the ink sheet can be avoided.

Title: Fuel injection device and its method
Inventor: OBO SHIGERU
IPC: F02D41/20
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To obtain rapid valve opening responsiveness by making a current flow to an inductor prior to injector valve opening, previously accumulating electromagnetic energy in an injector magnetic circuit, and forming a series circuit of the inductor and an injector magnetic coil at the time of injector valve opening so as to make the same current flow by a switching element. SOLUTION: Prior to fuel injection, a transistor switch 600 is switched on by an inductor current control signal, and a current flows to an inductor 200. At this time, a switch 610 is still in an off state, so that a current is not flowing to an injector electromagnetic coil 300. The instant a fuel injection control signal instructs injection, the switch 600 is switched off, and the switch 610 rapidly changes into an on state. At this time, an inductor current is suddenly lowered the instant the switch 600 is switched off, and then shifted at a time constant determined by a series circuit of the inductor 200 and injector electromagnetic coil 300, and the inductor current continuously flows through the injector electromagnetic circuit 300.

Title: Method and apparatus for controlling fluid pressure cylinder
Inventor: UENO TOYOAKI
IPC: F15B11/02
Filed: 1982-12-27
Abstract: PURPOSE:To stabilize the speed of a piston while it is shifted from high speed movement to high output movement by controlling the degree of opening of a flowrate control valve for supplying pressurized fluid by a preset valve opening coefficient. CONSTITUTION:As the pressure of oil in an oil feeding pipe 34 exceeds a preset pressure, a solenoid 38 operates, and a flow passage changeover valve 39 is changed over to the side of a tank line 40, and by this, the speed of a piston 43 tends to fall. However, an operating condition detector 48 detects the open/ close movement of the flow passage change-over valve 39, and it supplies a displacement value signal to an opening coefficient setter 49, and this signal is then supplied to a flowrate control valve control unit 52, and by this command, the opening of a flowrate control valve 35 becomes larger. Consequently, the piston can maintain high and constant speeds.

Title: Debugging method
Inventor: SAKAMOTO KEIJI
IPC: G06F11/36
Filed: 1982-12-29
Abstract: PURPOSE:To improve the efficiency of a debugging method by allowing only an interpreter which is set in debugging mode to escape to debugging processing while others continue system operation. CONSTITUTION:The interpreter corresponding to respective terminal devices checks whether a set program number is equal to the own program number or not. Then, an instruction analysis is taken by a normal application control program. On the other hand, when some program number is equal to the set number, it is judged that the device is set in a debugging mode, and the interpreter escapes from normal processing to enter the debugging mode. Then, a debugging program is executed until the debugging mode ends. In this case, the interpreter is in the debugging mode and performs debugging processing, but the interpreter corresponding to other terminal device carrys on a series of operation without stopping.

Title: Hermetic type motor-driven compressor
Inventor: HIRAHARA TAKUO
IPC: H02K55/00
Filed: 1987-09-18
Abstract: PURPOSE:To avoid the generation of the Joule heat of a winding, by forming the winding with superconducting material for setting the intermediate value of critical current density between the current density of the winding under the maximum operating condition of a compression element, and the current density of the winding at the time of starting. CONSTITUTION:A motor element is provided with a stator 2a and a rotor 2b. The winding 2c of the stator 2a is formed with superconducting material for generating a superconducting state at specific critical magnetic flux density, critical current density, and critical temperature. Then, the critical current density of the superconducting material is set to come to an intermediate value between the current density of the winding under the maximum operating condition of a compressor, and the current density of the winding at the time of starting. As a result, the Joule heat of the winding is hardly generated, and the motor element including the winding can be retained at a low temperature.

Title: Measurement device for convergence
Inventor: SATOU YOSHIO
IPC: H04N17/04
Filed: 1983-12-14
Abstract: PURPOSE:To decrease the time of measurement and to improve the measurement accuracy by measuring the convergence (color blurring) of optional plural positions on a color TV screen within the minimum number of fields. CONSTITUTION:The convergence measurement order is shifted to positions of vertical patterns VP1-VP5 in response to the traveling order of a scan line S of an ITV camera, and the measurement positions are shifted as P1 P6 P11  P21... P25. The position (number) of the line S is shifted successively at and after the head position to measure the time tRm (tGm, tBm) between a horizontal synchronizing signal and the vertical pattern. Then these 25 measurement positions P1-P25 are measured in a single field. The measurement time of those 25 positions is defined as 1/60secX1 16.7msec. This means a big reduction of the measurement time. Then the measurement is carried out at the position (x) in order of P11 P16 P21 P1 together with a shift given to the number of the line S. Hereafter the measurement is performed in the same way at all positions P1- P25 with five lines S shifted successively. In such a way the measurement accuracy is improved.

Filed: 1993-09-21
Abstract: PURPOSE:To provide a forming method for a capacitive nitride film having a high dielectric strength and a small leak current. CONSTITUTION:A polycrystalline silicon film 103 as a lower electrode is formed on a semiconductor silicon substrate 101, an acid resisting nitride film 104 is formed on the lower electrode 103, thereafter a capacitive nitride film 105 is formed by the LPCVD method. When forming this capacitive nitride film 106, HCl gas is introduced near the surface of the substrate 101 and HCl is efficiently adsorbed to the film surface. The adsorption of HCl specially and selectively restricts the reaction of the portion having silicon surface on a silane-based reaction species (SiCl2, SiH2) so that the creation of Si-Si bonding in the growth of nitride film is restricted. As a result, the improvement in the dielectric strength of nitride film and reduction in leak current can be realized.
