Title: Method of coupling semiconductor laser and photo-fiber
Inventor: KURATA NOBORU
IPC: G02B6/42
Filed: 1978-06-23
Abstract: PURPOSE: To reduce noises in laser output without damaging the efficiency of coupling, and to stabilize luminescence, by positioning a long axis of a tilt, incident end surface of a photo-fiber on a junction surface of a laser, and by disposing a short axis in a vertical shape to the long axis.  
     CONSTITUTION: An axis 12 is tilted to a base line 11 so that rays on the base line 11 from a laser 1 be projected to an end surface 9, be refracted and advance in a fiber 4 along the axis 12. A luminous angle of the stripe type semiconductor laser 1 is small on a junction surface 8 and large in the direction vertical to the surface 8, and the laser has oval luminous distribution. When a long axis of an incident end surface is located on the surface 8, a short axis 14 is vertically arranged to the surface 8 and the fiber axis 12 is tilted to the base line 11 on the surface 8, an end surface of the fiber forms oval when viewing from the luminous surface side and agrees with the luminous distribution 10, and the efficiency of coupling is hardly lost. The end surface 9 inclines to the base line 11, the reflected rays of the end surface 9 do not return to a luminous surface 2, noises in output rays are little and luminous action is stable.

Title: Continuous pickling method of metal strip
Inventor: KIMURA TOMOAKI
IPC: C23C2/02
Filed: 1978-06-28
Abstract: PURPOSE:To enable descaling of high performance to be performed with inexpensive running costs by supplying the metal strip of temperature higher than acid solution temperature to a pickling bath and maintaining the acid solution at a high temperature. CONSTITUTION:The temperature of a strip 21 whose leading and trailing ends are connected by a welder 3 is measured with a thermometer 7 and when it is higher than a desired temperature, the strip is passed through a cooling unit 11, after which it is pickled. At this time, the temperature of the strip 21 is controlled by measuring the temperature of the strip 21 immediate before the first pickling bath 12 with a thermometer 10 and sending a command to the cooling unit 11. The metal strip 21 having been controlled to adequate temperature is subsequently passed through pickling baths 12, 13, 14 and is removed of the acid solutions by a water jet washing bath 15, hot water wahing bath 16 and drying oven 17, after which it is taken up to a take-up machine 20. This method enables descaling to be accomplished without consuming large amount of heat energy. Also, the descaling of high performance is accomplished by controlling the speeds of passing and the concentrations of acid solutions in place of temperature controlling of the strip 21.

Title: Discharge lamp lighting device and luminaire
IPC: H05B41/16
Filed: 1992-03-31
Abstract: PURPOSE:To prevent a flame failure when a discharge lamp is deeply dimmed at a low temperature. CONSTITUTION:The output voltage of an inverter circuit 1 is detected by a power detecting means 3, and the output voltage of the inverter circuit 1 is compared with an output reference voltage source E1 by an operation amplifier OP13 and outputted via feedback. The lamp voltage of fluorescent lamps FL1, FL2 is detected by a lamp voltage detecting means 4, and the lamp voltage is compared with a lamp reference voltage source E2 by the operation amplifier OP13. When the lamp voltage is higher than the lamp reference voltage source E2, it is lowered by an operation amplifier OP12. Transistors Q1, Q2 are controlled by the output from the operation amplifier OP3. Even if the voltage of the fluorescent lamps FL1, FL2 rises at a low temperature, the detected lamp voltage is lowered relatively to the lamp reference voltage source E2, thus the lamp voltage can be corrected, and the flame failure of the fluorescent lamps FL1, FL2 can be prevented.

Title: Heat sensing device of electric stove
Inventor: OONISHI SHIGEZOU
IPC: F24C7/08
Filed: 1984-04-18
Abstract: PURPOSE:To make the temperature of a heat sensing element closely follow the temperature of cooking stuff by a structure wherein the heat sensing element is imbedded in conductive material and positioned at the center of a contacting plate by covering the circumference of the element by a spring retainer so as to constitute a cooling chamber and at the same time the radiant heat, which is emitted from a heater and received by the contacting plate, is rediated downwards by means of a middle liner. CONSTITUTION:A plurality of arms 23 are arranged at the upper part of a middle liner 15 at the positions corresponding to the claws 14 of a liner part 13. A spring retainer 17 is held at the center of a contacting plate 7 by means of ribs 24 provided at the root of each arm 23 and at the same time the flange 16 of the spring retainer 17 is brought into close contact with the inside surface of the contacting plate 7 by means of the claws 14. Because the liner part of the spring retainer 17 is separated from the middle liner 15 by means of the ribs 24, the heat of the middle liner 15 is prevented from transmitting to the spring retainer 17. Because of the close contact with such small ribs 24, the major part of the radiant heat transmitted to the liner part 13 of the contacting plate 7 is returned the outside of a pan bottom 6 through the peripheral edge of the contacting plate 7 and only a small portion of the remaining heat is transmitted to the spring retainer 17, while almost all the remaining heat is discharged to a lower space by means of a middle liner 15, resulting in preventing the temperature of the heat sensing element 12 from raising. Furthermore, because the heat sensing element 12 is also positioned at the center of the contacting plate 7, the detection accuracy of the element 12 is improved.
