Title: Programed exposure controller for camera
Inventor: YONEDA OSAMU
IPC: G03B7/087
Filed: 1981-11-06
Abstract: PURPOSE:To eliminate the need for changing programs when the full-aperture value of a lens changes by making the combination of shutter second time and aperture value independent of the full-aperture value. CONSTITUTION:The plus input of an OP amplifier A1 of photometric circuits is biased by the voltage proportional to the absolute temp. of a reference voltage source EA, and the terminal voltage of a variable resistor VR1 is proportional to the absolute temp. The output of an operational amplifier A5 and an output P1 for selecting the shutter second time are applied to a comparator CP1. In the prescribed relation of both outputs, the control magnet Mg1 of a stop 1 is energized. A control circuit 3 reproduces the shutter second time according to the voltage of a storage capacitor C1 and energizes a shutter control magnet Mg2 whereby exposure is completed.

Abstract: PROBLEM TO BE SOLVED: To provide a working method of a tube with grooves on its inside surface for executing stable forming without affecting on the groove shape even when wear is generated on the surface of a grooving plug. SOLUTION: A tube stock 8 which is fed from the tube feeding side is reduced with a floating plug 2 and holding die 1. A motor 9 is rotated while being gradually moved toward the tube drawing side and rolling balls 5 which are housed in a working ring 21 arranged on the outside surface of the tube are rotated in the circumferential direction of the tube while gradually continuously or intermittently moving for the drawing side of the tube. At this time, the grooving plug 3 is rotated with the grooves carved on the peripheral surface of the grooving plug 3 by drawing the tube. In such a way, the diameter of the reduced tube stock 8 is further reduced by pressing the tube stock 8 against the grooving plug 3 with the rolling balls 5 and also spiral-shaped fins 6 which match the grooves of the grooving plug 3 are transferred on the inside surface of the tube.

Abstract: PURPOSE: To improve the thermal efficiency of a gas turbine, by using a heat source except for the gas turbine to heat air discharged from a compressor for the turbine.  
     CONSTITUTION: Air A 1  is compressed  by a compressor 3. The highly pressurized air A 2  is conducted to a heat exchanger 9 and heated by high-temperature combustion gas A 5  from an industrial furnace 6. The air A 2 ' of thus heightened pressure and temperature is conducted to a combustor 5. Fuel F 1  is blown into the combustor 5 so that the fuel is burned and the air A 2 ' is changed into high- temperature combustion gas A 3 . The gas A 3  is conducted to a turbine 4. The exhaust gas A 4  from the turbine 4 is conducted as buring air to the industrial furnace 6. Fuel F 2  is blown into the furnace 6 so that the fuel is burned. Heat generated in the furnace 6 is used for a prescribed process. The high-temperature combustion gas A 5  imparts heat to the air A 2  in the exhanger 9 so that the gas A 5  becomes air A 5 ' of reduced temperature. The air A 5 ' acts to generate steam in a waste heat boiler 7 so that the air becomes combustion gas A 6 . The pressure of the combustion gas A 6  is heightened by a blower 8 so that the gas is released into the atmosphere.

Title: Production of low polarization dependent loss optical fiber coupler
Inventor: ABE ATSUSHI
IPC: G02B6/293
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To provide an optical fiber coupler which is low in PDL(polarization dependent loss) over a wide band, is high in peak wavelength isolation and has a low-loss characteristic by specifying the heating range at the time of twisting and clamping plural pieces of bare optical fibers and fusion stretching these fibers to a specific length. SOLUTION: The heating range at the time of clamping plural bare optical fibers for fusion stretching the optical fibers is specified to >=10,000μm. This coupler is gentle in the taper shape of the fused parts and, therefore, exhibits the low PDL value and the shortening of the coupler length is made possible. When the heating range exceeds 20,000μm, the coupler length increases and since there is the limitation on the device, the range of <=20,000μm suffices. The two optical fibers 1, 2 are clamped by the clamping parts 5 of a moving stage 3 and the coating parts of the fibers 1, 2 are partically removed to form the two bare optical fibers. These bare optical fibers are twisted and are heated and fused at >=10,000μm by the burner 4.  Further, monitor light is made incident from one end of the optical fiber 1 and is received by photodetectors 9, 10, by which the coupler length is controlled.

CONSTITUTION:A semiinsulative GaAs substrate is exposed to an oxidizing atmosphere. The C on the substrate surface is converted to CO2, a Ga single unit is converted to Ga2O, and an As single unit is converted to AsO3 respectively by the above-mentioned heat treatment. Then, said substrate is heated up in a vacuum atmosphere. The GaO2 and the AsO3 are sublimated by the above-mentioned heat treatment. A GaAs crystal layer is grown on the substrate, the surface of which is cleaned by the above-mentioned procedure, by performing a molecular beam epitaxial growth method (MBE). According to this method, the single unit substance located on the substrate surface, which is the cause of crystal defect generating in the crystal layer grown when the MBE is performed, is converted to a reactive deposit which can be aublimated easily and it is removed in the heat treatment which will be performed subsequently, thereby enabling to have a very clean surface of the substrate. Accord ingly, an excellent crystal layer, having few crystal defects, can be obtained on the above- mentioned substrate.
