Title: Manufacture of photovoltaic element
Inventor: MORI KOSHIRO
IPC: H01L31/04
Filed: 1988-03-30
Abstract: PURPOSE:To decrease manhours by simultaneously cutting a first substrate, a second substrate for protecting the surface and a third substrate for reinforcement and holding and arraying a plurality of solar cells singly separated on a fourth substrate in a matrix manner. CONSTITUTION:All of laminated substrates up to first - third substrates 1-3 except a fourth substrate 4 are cut into laminated multi-layer boards, and a plurality of independently detached photovoltaic element 5 are arranged and held onto the fourth substrate 4, thus manufacturing the title photovoltaic element. When a solar cell is used as the photovoltaic element 5, terminal sections 6 at a positive pole and a negative pole are fitted at both ends of the photovoltaic element normally, and leads are led out to the terminal sections 6 through a heat seal method and soldering. The leads can be led out in such a manner that sections laminated onto the terminal sections and superposed to the terminal sections are employed previously as opening sections 7 in the second - fourth substrates 2-4 laminated onto the first substrate. Accordingly, the manufacture of the photovoltaic element in which processes are treated continuously by the substrates in large size is acquired, thus reducing the complicatedness of the treatment of each photovoltaic element in conventional devices and the manhours.

Title: Casting method
Inventor: UOHARA MASAMI
IPC: B22C9/24
Filed: 1985-04-10
Abstract: PURPOSE:To prevent the exfoliation of molding sand and the carry over of the exfoliated molding sand into a cavity by interposing a plate material which is bulged in the middle and has an aperture smaller than runners between the joint surfaces of the runners in upper and lower directions in a casting mold. CONSTITUTION:A core assembly 1, a cope 8 and a drag 9 are assembled and thereafter a molten metal is poured into the mold through a sprue 13. The molten metal is poured through a runner 20 into a cavity 11. The molten metal passes the aperture of the plate material 15 interposed in the midway of the runner 20 and flow downward. The diameter of the aperture is smaller than the diameter of the upper runners 12 above and below the material 15 and the intermediate runner 6 and therefore even if a large amt. of the molten metal is poured into the sprue 13, the molten metal flows gently by each small amt. into the cavity 11 from the lower part of the runner 20 for the beginning when the pouring is started. The exfoliation of the molding sand is thus obviated from the runner 20 up to the cavity 11. The material 15 is thereafter melted and the diameter of the aperture is gradually increased, by which the molten metal speed is increased but some amt. of the molten metal is already poured into the cavity and therefore there is no disturbance of the flow and the exfoliation of the molding sand is obviated.

Filed: 1984-04-19
Abstract: PURPOSE:To keep tube voltage constant independently of voltage variation of commercial power source by previously setting voltage which is applied to one input terminal of an error amplifier circuit so as to obtain tube voltage suitable for X-ray photographing. CONSTITUTION:Tube current applied to an X-ray tube 6 is detected with a rectifier circuit 21 which is connected to a secondary junction of a high voltage transformer 4. Detected voltage V7 is inputted to one input terminal of an error amplifier circuit 23. A setting voltage V8 which is regulated by a regulating circuit 22 is applied to the other input terminal. Pulses corresponding to output voltage of the error amplifier circuit 23 is oscillated from a pulse-amplitude control oscillating circuit 24, and converted to high-frequency wave with a high- frequency wave oscillating circuit 25, and boosted with the high voltage transformer 25 to apply to a filament of the X-ray tube 6. When detected voltage V7 is low compared with setting voltage V8, tube current is adjusted so as to increase. When voltage V7 is high than voltage V8, tube voltage is adjusted so as to decrease. By previously setting voltage V8 so as to obtain tube voltage suitable for X-ray photographing, the tube current can be kept constant.

Title: Fiber type phase shifter
Inventor: OKAMOTO KATSUNARI
IPC: G02B6/14
Filed: 1982-05-11
Abstract: PURPOSE:To obtain a fiber type phase shifter which has a small size and high performance and is simple in coupling system by using a single polarization fiber provided with a stress applying part having the coefft. of thermal expansion differing from that of a core as a phase shifter. CONSTITUTION:A stress applying part 2 is provided in addition to a core 1 and a clad 3 to a single polarization fiber. B2Os, etc. are added to the fiber and the fiber is cooled after drawing in order to make the coefft. of thermal expansion larger in the part 2' than in the clad 3; therefore, tensile stress is generated in the axial X direction in the core 1. The phase difference for the two polarization modes of the single polarization fiber can be made different by integer times of pi/2 by the double refraction occuring in the difference in stress in the core 1. Therefore, if such single polarization fiber is used, the fiber type phase shifter which has a small size and high performance and permits easy connection to an optical fiber is obtained.
