Title: Method for filling insulating isolation groove
Inventor: MIENO FUMITAKE
IPC: H01L21/76
Filed: 1985-08-02
Abstract: PURPOSE:To reduce the cost and to improve the yield of wafers by omitting the mechanical polishing step by a method wherein a silicon-rich surface layer is formed on the surface of an oxide film on the bottom of an U-shaped groove and this U-shaped groove is filled by the preferential growth of silicon on said surface layer. CONSTITUTION:A substrate 1 on which an U-shaped groove 3 is to be formed is coated with an oxide film 4 and a resist film 6 on which the groove is to be opened is laminated. Silicon ions are projected to the bottom of the groove 3 by ion implantation. Consequently, a silicon-rich surface layer 7 is formed on the oxide film 4. After removing the resist film 6, gas-phase growth of silicon is made by hydrogen reduction technique using trichlorosilane. As a result, the groove 3 is filled with poly-silicon 8 and on the surface of other parts of the substrate 1, silicon does not grow. Thus, a mechanical polishing step can be omitted and the reduction of cost and the improvement in yield of wafers can be attained.

Title: Semiconductor laser device
Inventor: HIRONAKA MISAO
IPC: H01S5/00
Filed: 1983-09-17
Abstract: PURPOSE:To contrive to improve the absorption efficiency for laser beams at the detector part and the operating characteristic by a method wherein the band gap energy of the light receiving part of the active layer at the detector part is enabled to become smaller than that of the active layer at the diode part. CONSTITUTION:The width W2 of the stripe groove 3c of the detector part 12 is larger than the width W1 of the stripe groove 3a of the laser diode part 10, and is formed in the relation of W1<W2. Therefore, in lamination of the active layer 5c of the detector part 12, the growing speed on the part of a stripe groove 7c becomes higher than the growing speed in lamination of the active layer 5a of the laser diode part 10. Accordingly, a curved active region 13 is formed in the layer 5c, and the band gap of the region 13 of the detector part 12 becomes smaller than that of the layer 5a of the laser diode part 10. Since the band gap energy of a curved active region 11 of the detector part 12 is smaller than the energy of the incident laser beam, the absorption efficiency for the incident light in the region 11 is large, and the detection ability improves.

Abstract: PURPOSE:To miniaturize an ignition coil and reduce the cost by feeding/-shutting the current to/off primary coils which are respectively coiled around two core parts for the primary coils magnetically connected to the core parts for secondary coils by an igniter. CONSTITUTION:In an ignition device 10, when transistors 50, 56 of an igniter 48 are turned OFF from the ON condition to generate the potential of high voltage to a secondary coil 42, a magnetic field part 28 for an ignition plug forms the enclosed magnetic field, and the magnetic force generated in the magnetic field part 28 for the ignition plug is not applied to magnetic field parts 30, 32 for other ignition plug. Thus, no potential of high voltage is generated in secondary coils 44, 46 to be connected to ignition plugs 6, 8 other than the secondary coil 42 to which an ignition plug 4 to be discharged is connected. An ignition coil 12 can be integrated, and a large diode to prevent the discharge of the ignition plug other than the ignition plug to be discharged need not be provided.

IPC: F02D9/08
Filed: 1980-12-04
Abstract: PURPOSE: To reduce fluctuations in air fuel ratio during starting and to enable air fuel control by providing a means to increase suction air which starts its operation when the engine starts and completes its operation as warming up progresses.  
     CONSTITUTION: A bypass channel 25 having a solenoid valve 23 is provided to bypass a throttle valve 5b of a carburetter 1. The solenoid valve 23 is opened by a control unit 12 when the engine starts and supplies fuel to the engine from a starting fuel channel 27.

The throttle valve 5a is further provided with a means to increase suction air which comprises a negative control solenoid valve 20 and a diaphrgam valve 15. With this construction, the solenoid valve 20 increases a transmission rate of negative pressure to a negative pressure chamber 18 when the engine starts at a cold temperature and opens the throttle valves more, but reduces the transmission rate of negative pressure to the negative pressure chamber 18 as the engine is warmed up.

Filed: 1988-07-12
Abstract: PURPOSE:To cause the title system to make picture recording and reproduction with a double increased number of frames by providing 1st and 2nd magnetic heads respectively facing both side surfaces of a video floppy. CONSTITUTION:A magnetic head 7 for odd-numbered fields and magnetic head 8 for even-numbered fields are provided in a state where their gap sections are faced to each other on both sides of a video floppy 4, with the gap sections being brought into contact with the floppy 4. The video of an object taken by means of a still camera is synthesized with synchronous signals after photoelectrical conversion and sent to a switch 9 synchronously to the index signal of a video floppy 4. Then video signals of odd-numbered and even- numbered fields are recorded on each surface of the floppy 4 by means of the heads 7 and 8. At the time of reproduction, on the other hand, video signals of the odd-numbered and even-numbered fields are regenerated by the heads 7 and 8 and synthesized in the order of odd-numbered field signals and even- numbered field signals, with the switch 9 being switched by the index signal again. The synthesized video signals are regenerated at a TV set. Thus picture recording and reproduction can be performed with the double increased number of frames.

Abstract: PROBLEM TO BE SOLVED: To prevent an influence on control of an automatic driving device by a foreign matter by providing a slant portion to form a passage shape of a downstream side communicating passage in such a way that a passage area at a differential pressure chamber side at a side on which a pressure switch is provided is gradually broader than a passage area at a side facing to a discharge side passage. SOLUTION: A valve body 15 is connected to a discharge side of a pump portion 14 to form a discharge side passage 16. A resistor 17 is provided on the discharge side passage 16 and a diaphragm 18a, an upstream side communicating passage 19 and a downstream side communicating passage 20a are provided so as to detect a differential pressure of an upstream side and a downstream side of the resistor 17. A slant portion 20b is provided to form a passage shape in such a way that a passage area of a differential pressure chamber side on which a pressure switch 22 is provided is gradually broader than a passage area at a side facing to a discharge side passage 16. The passage area at the side facing to the discharge side passage 16 is made broader than the passage area of a switch communicating port. Thereby, even if a foreign matter is raised from a water source by a pump, control of an automatic operating device of a pump is hardly influenced by the foreign matter.
