Title: Light emitting device and manufacture thereof
Inventor: AKETOSHI TOSHIMI
IPC: H01S3/0933
Filed: 1989-02-09
Abstract: PURPOSE:To obtain a light emitting element structure which emits a laser beam efficiently and stably without an optical system by a method wherein a first clad layer, an active layer, and a second clad layer are provided to a semiconductor single crystal layer, and a stripe-like wavelength conversion section is provided close to the active layers. CONSTITUTION:An n-type clad layer 2 and an active layer 3 are laminated on an n-type substrate wafer 1, furthermore a p-type clad layer 4 is deposited thereon, and the face of the wafer 1 vertical to the layers is cleaved to form a light emitting structure of this design. When a forward current is made to flow between a p-side electrode 6 and an n-side electrode 5 of the semiconductor laser, the active layer 3 emits light rays of LED type wavelength spectrum. The light rays are mirror-reflected by opposed cleavage planes 9 to grow to be an LD-type wavelength spectrum intense only in resonance frequency. Here, to make the spectrum grow to be a super-luminescent type spectrum, the gap between an Nd doped region 7 and the layer 3 is made to have a length of the order of the emission wavelength, and the cleavage plane 9 is subjected to an AR coating treatment. By this setup, a stripe-like wavelength conversion layer 7 doped with trivalent rare earth ions is excited by light rays emitted from the active layer which have a required intensity in a specified wavelength region to obtain a laser output excellent in thermal stability.

Filed: 1989-02-09
Abstract: PURPOSE:To easily understand the cursor position of a pointing device without losing sight thereof at the switching time point of a window by restoring the display position of a cursor to a specific position in a screen and displaying it, based on the detection output of a window operation detection processing means. CONSTITUTION:At the time point of generation or erasion of a window, or switching of the front free display, etc., a window operation detection processing means 100 detects its updating operation, and informs the restoration to the home position of a cursor 63 to a home position restoring processing means 53, by which the display position of the cursor 63 moves to the home position. In such a manner, an operator knows that the cursor 63 is always position in the home position, when the window is switched, it is eliminated to lose sight of the display position of the cursor, and the input/output processing of the next window can be easily executed.

Title: Method of recovering oily hydrocarbon fuel or such from plastic scrap
Inventor: FUJITA ISAO
IPC: C10G1/10
Filed: 1986-02-14
Abstract: PURPOSE:To efficiently recover the titled fuel having high quality, by thermally decomposing pulverized plastics scraps through carbonization thereof in a particular carbonization oven and cooling the separated carbonization gas after removal of mist to allow it to condense, thereby completely removing water. CONSTITUTION:Plastics scrap material which has been pulverized so as to have a size of 20-50mm is fed from a hopper 1 by means of a transfer fan 2 through an airlift into a cyclone 3, where air is separated therefrom. The scrap is then transferred to a charging hopper 4 and fed, by means of a screw conveyor 6 equipped with rotary valves 5, 7, into a heat resistance and anticorrosive carbonization oven 8 provided with a hermetically sealed horizontal heating pipe rotatably. The heating pipe is heated by burners 9, 10 to uniformly carbonize the material. The carbonization gas thus generated is fed through a discharging port 88 into a separator 11, where mists are separated therefrom. The gas is then allowed to cool in condensers 12, 13, thereby condensing it. The condensate thus obtd. is applied to an oil-water separation in a trap separator 14 and an L-L separator 15. The oil which is a oily hydrocarbon fuel is passed through a vacuum resistant pump 16 and a mist removing filter 17 and stored in a storage vessel 18. On the other hand, the residue containing by- products is transferred to a residue accommodating portion 84 and then transferred to a residue tank 26 through a screw conveyor.

Title: Carburetor
Inventor: TAMURA MAKOTO
IPC: F02M7/10
Filed: 1982-02-26
Abstract: PURPOSE:To prevent a main air bleeder from getting clogged due to fuel vapor generated by the rise in temperature, by placing the lower end of a mixing tube above the liquid fuel level in a main fuel passage. CONSTITUTION:A mixing tube 8 is placed above the liquid fuel level in a main fuel passage 7. When the temperature of a carburetor has risen, some of fuel in the passage 7 is evaporated but the fuel vapor does not condense in the mixing tube 8 because its lower end is above the liquid fuel level in the main fuel passage. For that reason, a main air bleeder 9 is kept from getting clogged with condensed fuel. This results in feeding a stable mixture to an engine.

Filed: 1978-03-13
Abstract: PURPOSE:To make possible the automatic fine adjustment of the tool diameter correspondingly to  the working error of the low hole, by settling through the axial movement the working diameter  of the mandrel insertd into the cylindrical casing whose tip is provided with taper rolls at a  uniform pitch. CONSTITUTION:In the case of burnishing the lower hole C of the material B to be worked, being  clamped by the holder A, the entire apparatus is moved down with the downward movement of  the spindle 14; when the stopper 26 strikes the holder A, the downward movement of the cylinder  20 is stopped. Under this condition, the position of the stopper 26 is settled so as to make the face  pressure given to the lower hole C of the roller 11 to be lower than the required face pressure,  even though the manufacturing error is taken into consideration. Next, while the fluid of the  cylindrical casing 32 is being discharged through the path 23 at a constant rate, the sleeve 30  together with the spindle 14 are moved downward for moving the mandrel 12 forward, and for  expanding the roller 11 outward. Then, when the thrust force of the mandrel 12 becomes constant, the fluid discharge through the path 23 is stopped, and the mandrel 12 is stopped there.  Hereupon, the roller 11 is impressing a constant face pressure on the lower hole C independently  of its diameter error.

Abstract: PURPOSE: To provide a semiconductor laser which can be improved in the controllability of the refractive index difference between the inside and outside of its waveguide and can be improved in output yield in the horizontal transverse mode and the manufacturing method of the laser. CONSTITUTION: In a ridge waveguide type semiconductor laser in which part of an optical waveguide is constituted as a mesa stripe, an etching buffer layer 7 is formed below the mesa stripe 10 and current block layers 11 having the same refractive index as that the buffer layer 7 has are formed on both sides of the stripe 10. At the time of performing etching for forming the stripe 10, the allowable etching depth area corresponding to the thickness of the buffer layer 7 is obtained and the controllability of the difference of the refractive index is improved. In addition, because of the block layers 11 having the same refractive index as the buffer layer 7 has formed on both sides of the stripe 10, the smoothness of the effective refractive index of the side sections of an optical waveguide in the direction of the waveguide is improved and the loss of the waveguide is reduced.  Therefore, the output yield is improved in the horizontal transverse mode.

Abstract: PURPOSE:To simplify handling and shield surely a circuit substrate electromagnetically to operate a computer stably by only inserting a cartridge to a slot to not only connect the circuit substrate and signal lines of a connector but also connect electrically a shield plate of the cartridge and a shield spring of the slot. CONSTITUTION:A shield spring 23 where plural contact pieces 22 are arranged on a side face of a connector in the lengthwise direction of the connector 20 is fixed to a shield plate 26 of a computer body by a screw 25. Before a circuit substrate 6 of a cartridge 19 is connected to the connector 20, a length L from the center of the connector 20 to tops of contact pieces 22 of the shield spring is set to a value longer than a length l from the center of the circuit substrate 6 of the cartridge 19 to a shield plate 7. Therefore, contact pieces 22 of the shield spring are bent by a shield plate 13 and are pressed to the shield plate 13 by the elastic force of contact pieces 22 themselves when the circuit substrate 6 is connected to the connector 20. Thus, the shield spring 23 and the shield plate 13 are held in the same potential.
