The silicon wafer is of diameter of 300 mm and larger sliced from a single-crystal silicon ingot pulled by CZ method, the surface is mirror-polished and cleaned with ammonia based cleaning solution, and the number of particles of 0.083 &mgr;m and larger in size detected on its main surface is 120 and smaller and/or particles of 0.090 &mgr;m and larger in size is smaller than 80.
摘要:
An ATM switching system concentrates cell streams, which are output by respective ones of a plurality of line interfaces, by a concentrator, enters a resulting cell stream into an ATM switch unit, deconcentrates cells, which have been switched by the ATM switch unit, by a deconcentrator on a per line interface basis and sends the cells to lines. Each line interface converts a VPI/VCI included in the header of a cell that has entered from a line to an internal cell address having a number of bits smaller than the number of bits of the VPI/VCI. Each unit in the ATM switching system performs management of various data and controls cell switching based upon a converted cell address without relying upon the VPI/VCI. The line interface restores an internal cell address, which is included in the header of a cell that enters from the side of the ATM switch, to the VPI/VCI and sends the cell to a line.

摘要:
An electrolyte feeder for battery including an electrolyte container, said container comprising a shell body filled with an electrolyte in a plurality of spaced cell units, equal in number to the number of individual cells in a dry changed storage battery, each of said shell bodies having a filling tube, said filling tubes being spaced to coincide with the spacing between filling ports of said battery to enable the filling tubes to fit into the corresponding one of the filling ports, a thin film being formed at a tip end of the filling tube, and said thin film sealing up each shell body.
摘要:
A welding technique closely contacting a light transmissive second member to a first member and radiating deflection-controlled laser light from a second member side to weld both first and second members at a weld interface thereof. A reflectance reducing means is formed by an incident angle adjusting step provided in a cover plate that is disposed on a light radiating surface side of the second member. The reflectance reducing means reduces incident angles of the light at the light radiating surfaces of the first and second members, thus reducing the reflection loss of the laser light at the light radiating surfaces and improving the welding efficiency.

A method for preparing a ruthenium catalyst, including a step of reducing a ruthenium catalyst precursor by holding the ruthenium catalyst precursor in an aqueous solution containing a metal salt at a temperature within the range of more than 180° C. and 220° C. or less and a hydrogen partial pressure within the range of 0.6 MPa or more and 5 MPa or less. A method for producing a cycloolefin, including a step of preparing a ruthenium catalyst by the method including a step of reducing a ruthenium catalyst precursor in an aqueous solution containing a metal salt by holding the ruthenium catalyst precursor at a temperature within the range of more than 180° C. and 220° C. or less and a hydrogen partial pressure within the range of 0.6 MPa or more and 5 MPa or less, and a step of partially hydrogenating a monocyclic aromatic hydrocarbon by use of the ruthenium catalyst obtained.
摘要:
A packaging bag is provided with a bag body and thermoplastic resin-made reinforcing members provided at the outer edge of the bag body. A window is provided in each reinforcing member. In forming the packaging bag, the bag body is placed between a pair of molds respectively having recesses to clamp these two molds so that a corresponding pair of the recesses are opposed to each other. Thereafter, in order to form the reinforcing members at the outer edge of the bag body, melted or softened thermoplastic resin is injected to fill cavities formed by the recesses of the thus clamped molds. Each of the cavities of the molds is formed so as to coincide with an outer shape of the corresponding reinforcing member. A projection extends from the bottom face of each recess at a part of the cavity corresponding to a part of each reinforcing member on which the window is provided. The outer edge of the bag body placed between the two molds is placed inside the cavities in a state of being held between the two projections.
摘要:
A vehicular lamp in which a weld surface of a weld portion provided on a translucent cover is pressed against a surface to be welded that is formed on a lamp housing, and the translucent cover and the lamp housing are welded by a laser light irradiated from a welding head on the weld portion. The welding head is moved, during the method of making the lamp, along the weld surface, and the angle of the welding head while moving is varied depending on the orientation of the weld surface so that the orientation angle variation amount of the weld surface is set to be equal to or less than 0.5 deg/mm for areas which are adjacent in the moving direction of the welding head.
