Title: Photoelectric converter
Inventor: YOSHIDA TAKASHI
IPC: H01L31/04
Filed: 1989-10-12
Abstract: PURPOSE:To make it possible to improve a short-circuit current in a large degree and thereby to obtain a high conversion efficiency by a method wherein a first electrode of which a part of the surface at least is covered with a semiconductor layer of a first conductivity type is buried in dispersion in an intrinsic semiconductor layer and a second electrode is connected on one surface of the intrinsic semiconductor layer with a semiconductor layer of a second conductivity type interlaid between them. CONSTITUTION:A fiber electrode 1 constituted of a metal or other conductive substance and shaped in a mesh or a reed screen is covered with a p-type amorphous silicon layer 2. When an intrinsic or virtually intrinsic amorphous silicon film 3 not being doped is formed on this layer, it becomes a film having a construction wherein adjacent layers are brought into contact and integrated with each other as a film thickness becomes large, An n-type amorphous silicon layer 4 and further a metal layer-form electrode 5 are connected on one surface of the film, while a passivation film 6 constituted of a silicon nitride is connected on the other surface thereof, and thereby a solar cell of which a plus electrode is constructed of the fiber electrode 1 and a minus electrode of the layer-form electrode is completed. When a light is made to fall on the side of an intrinsic semiconductor layer whereon a second electrode is not provided, it reaches one layer, a photoelectric conversion layer, without passing through the doped layer, and therefore a photoelectric conversion efficiency is improved.

IPC: B23G5/06
Filed: 1986-11-06
Abstract: PURPOSE:To improve a chamber to a nut as well as to make a thread ridge for chamber starting accurately cuttable, by forming a stepped surface of no relief in the lead direction, along a lead of the thread ridge, on a thread ridge outer circumferential surface of the chamber part. CONSTITUTION:To form a stepped surface 8, a shaft center 9 of a tap 1 is tilted to a shaft center 21 of a grindstone 20 so as to cause the turning shaft center 21 of the round grindstone 20 and an outer circumferential surface of a chamber part 3 of the tape 1 to become paralleled, while the grindstone 20 is moved along a lead of the tap 1 in the state that the grindstone 20 and the tap 1 are rotated in the reverse direction to each other, and either of one side is moved in the radial direction, forming a recess there. Thus, since the stepped surface 8 is formed on the outer circumferential surface of a thread ridge 4 of the chamber part 3 of the tap 1, if a nut is pushed in toward the chamfer part 3 of the tap 1, an outer diametral edge 10 of the stepped surface 8 is positively chamfered to a lower hole inner diametral surface of the nut, thus there is no breakage of the thread ridge and a complete thread ridge 2 of the tap 1 is guided and moved to the screw groove formed in the chamber part 3, thereby such a nut excellent in accuracy is formable.

Abstract: PURPOSE:To circulate condensed liquid, reserved in a liquid reserving tank, to steam generator automatically and contrive the shortening of circulating time by a method wherein a liquid reserving section and the steam generator are connected through a non-return valve while the non-return valve is arranged so as to be opened only when a pressure in the steam generator is negative and closed when the same pressure is positive. CONSTITUTION:A non-return valve 12 is closed when a steam generator 1 is heated while the same valve 12 is closed when the heating of the steam generator 1 is stopped. When the heating of the steam generator 1 is stopped, steam is condensed suddenly in a radiator 5 and liquid is induced from a liquid reserving tank 7 into the radiator 5 while the inside of the steam generator 1 is evacuated. Accordingly, the non-return valve 12 is opened and the liquid in the tank 7 flows into the steam generator 1, therefore, the heat capacity of the steam generator 1 is consumed for heating the inflow fluid and the pressure in the steam generator 1 is reduced suddenly whereby the condensed liquid in the tank 7 is circulated into the steam generator 1 suddenly. According to this method, the circulating time is short and cool airflow does not flow out of the radiator 5 or the circulating time becomes extremely short and the cool airflow us bit blown off substantially.

Abstract: PURPOSE:To form a barrier layer continuously in the same film forming chamber by method wherein conditions under which an oxide superconductive thin film is formed on a substrate are set. CONSTITUTION:An YBa2Cu3Oy thin film is deposited on the crystal surface of an SrTiO3 substrate at a temperature of 650 deg.C through an RF magnetron sputtering method. Then, O2 is introduced into a film forming chamber, and the substrate is cooled down from a thin film forming temperature to a room temperature. In this cooling process, fine fissures are generated on the surface of the YBa2Cu3Oy thin film due to the phase transition or stress induced when the structure of the YBa2Cu3Oy thin film shrinks in the axial direction of C with the change of it in crystal structure from tetragonal system to rhombic system. The film forming chamber is vacuumized for forming a barrier layer on the fissured surface of the YBa2Cu3Oy thin film, and an amorphous YBa2Cu3 Oy thin film is deposited as thick as 300nm at a room temperature through a sputtering method. By this setup, a barrier layer can be continuously formed in the same film forming chamber.
