Patent JP-S58139102-A (JP)
Title: Laser working device
Inventor: FUKUI TADAHIRO
IPC: G02B6/44
Filed: 1982-02-12
Abstract: PURPOSE:To prevent damage of an optical fiber by the heat accumulated in the fiber during transmission of a laser beam by coating a surface protecting member having good heat conductivity on the surface of the optical fiber in which the laser beam is transmitted. CONSTITUTION:The surface of an optical fiber 10 which transmits gaseous CO2 laser beams is coated with a heat conductive resin 11 produced by mixing fine powder of carbon black or the like which is a material having good heat conductivity in a resin, whereby the surface is protected. The fiber 10 constituted in such a way is contained in a protective tube 12 of metal through an air layer 13. The air in the layer 13 is replaced with the outside air by an air circulator 14 through a tube 15. Even if the gaseous CO2 laser beam is transmitted in the fiber 10 for a long time, the heat generated therein is diffused by the resin 11 of good heat conductivity into the layer 13, and is further released to the outside through the tube 12 or the tube 15.

Title: Impregnation method for liquefied electrolyte in fuel cell
Inventor: TANAKA JUN
IPC: H01M8/04
Filed: 1986-02-03
Abstract: PURPOSE:To surely and quickly impregnate a liquefied electrolyte into an electrolyte plate, by placing a fuel cell in a vacuum container, evacuating the container of gas, and heating the fuel cell, to impregnate the liquefied electrolyte into the electrolyte plate. CONSTITUTION:A plurality of cell modules each comprising a positive and a negative electrodes and an electrolyte plate interposed therebetween are stacked together to constitute a fuel cell 4. A solid electrolyte is inserted into the electrolyte reservoir 12 of an upper holder 9. The fuel cell 4 is then placed in a vacuum container 5. The container 5 is evacuated of gas by a vacuum pump 7 to take air out of the pores of the electrolyte plates. The fuel cell 4 is heated by a heater 6 to melt the electrolyte in the reservoir 12 to cause it to permeate into the electrolyte plates while descending. The electrolyte is thus fully and surely impregnated into the electrolyte plates at a very much increased speed of permeation.

IPC: H03K21/02
Filed: 1982-02-13
Abstract: PURPOSE:To prevent the counting concerned, by adjuting a clock pulse frequency in accordance with a sliding speed of a brush which slides on a comb tooth like conductive pattern. CONSTITUTION:When a slide brush 102 is started from a start signal generating pattern 103 of one end of a comb toothlike conductive pattern, a start signal is inputted to a clear terminal of a counter 104, and counting of a clock pulse of a pulse generator 105' is started. In this case, when frequency of the clock pulse is adjusted in accordance with a speed of the brush, an output signal (a signal from an output ''8'') of the counter 104 can be made to one against one contact. This output signal is counted by a counter 108, and when contents of a preset signal source 110 coincide with the counting value, the sliding brush is stopped by an output of a comparator 109. In this way, for instance, a diaphragm value is decided.

Title: Voice answering device having automatic wraparound attenuating function
Inventor: KAMIYAMA YOSHIHIKO
IPC: H04M3/50
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To prevent the wrong recognition of PB signals even when the voice synthetic output contains such a frequency component that is misjudged as a PB signal at a PB detection part by performing the input/output of voices to a circuit interface part via a transformer and connecting a wraparound attenuating circuit between the output and input routes of a non-circuit side winding of the transformer. SOLUTION: This voice answering device includes a wraparound attenuating circuit added to a circuit interface part. A polarity non-inverted amplifier 9 of the attenuating circuit prevents the input given from the circuit side to input only the output signal of the voice answering device to a polarity inverted amplifier 10. An electronic volume 11 controls the level of the polarity inverted output signal via a control part. A comparator 12 attenuates a wraparound signal by an amount equal to a polarity inverted output signal component that passed through the volume 11.

Title: Variable venturi type carburetor
Inventor: KANOU KOUJI
IPC: F02M5/08
Filed: 1979-02-28
Abstract: PURPOSE: To keep the air fuel ratio at a preset level during low gear operation without discharging fuel vapor outdoors, by communicating a float chamber with a canister while the vehicle is out of or low gear operation and communicating the chamber with an air vent during normal operation.  
     CONSTITUTION: Fuel is measured in a clearance formed between an orifice 7 and jet needle 8 and then taken in a venturi 18. The passage to an air vent 11 is blocked, during idling, with a valve 14 of valve rod 15 fitted below a suction piston 4. Fuel vapor produced in the upper space of the float chamber 2 is adsorbed into a canister through a canister connecting port 13. As a throttle valve is wide open to increase the engine revolution, on the other hand, air flow increases and the piston 4 rises. Since the valve rod 15 also rises at the moment, the valve 14 blocks the canister connecting port 13 and communicates an air passage 12 with the air vent 11 to introduce fuel vapor into the suction passage.

Title: Stabilized light source for communication and instrument
Inventor: ASAKURA HIROYUKI
IPC: H01S5/00
Filed: 1985-02-07
Abstract: PURPOSE:To enable stable optical feedback to a semiconductor laser by unifying a lens for optical feedback and a reflecting mirror by a rod lens, adjacently arranging the semiconductor laser, shortening cavity length and image-forming output beams by the surface of the reflecting mirror once. CONSTITUTION:Output beams from a semiconductor laser element 1 are projected to a convergent rod lens 2 in length at half pitches. Beams projected to the convergent rod lens 2 are condensed onto the surface of a semitransparent mirror 3 formed by a metal evaporating film or a dielectric multilayer film. One part of beams condensed to an end surface is fed back to a light-emitting section for the semiconductor laser element 1 through an original optical path while using a condensed point as a novel light source by the semitransparent mirror 3, an external resonator is shaped by the semiconductor laser element 1 and the semitransparent mirror 3, and the Q value of the semiconductor laser element 1 is increased. Consequently, oscillation frequency is stabilized, and oscillation spectral purity is also improved largely. Since rod lens length L is also made shorter than conventional optical parts, the frequency of FM noises by the external resonator also takes an extremely high value, thus resulting in no trouble on a practical use.
