摘要:
A cleaning agent composition for a treated tool comprising an alkyl glycoside, a glyceryl ether, a hydrocarbon and water, and a cleaning process using the cleaning agent composition. The cleaning agent composition is used upon washing a surface of a silicone-treated tool, a liquid crystal-treated tool, a copper plate, or the like.
摘要:
A polishing composition comprising an improver of a ratio of a polishing rate of an insulating film to that of a stopper film, wherein the polishing rate of the stopper film is selectively decreased, comprising one or more compounds selected from the group consisting of a monoamine or diamine compound; a polyamine having three or more amino groups in its molecule; an ether group-containing amine; and a heterocyclic compound having nitrogen atom. The polishing composition can be used for removing an insulating film which has been embedded for isolation into a trench formed on a silicon substrate and sedimented outside the trench, thereby planing a surface of the silicon substrate.

摘要:
A detergent composition for cleaning a precision part, comprising an organic solvent, 5 to 30% by weight of a glyceryl ether having an alkyl group or alkenyl group having 4 to 12 carbon atoms, and 5% by weight or more of water. The detergent composition can be used for cleaning a precision part such as a metal part, an electronic part, a semiconductor part or a liquid crystal display panel.
摘要:
A movable automatic bolt driving apparatus sequentially drives a plurality of bolts positioned substantially in line on flanges of elongated concrete molding frame segments for producing columnar concrete products. The apparatus has a vertically movable bolt driver unit and an air-cylinder unit. When the bolt driver unit drives a bolt in a state that the socket and the bolt are non-concentrically engaged with each other, the air-cylinder unit causes to properly reposition the bolt driver unit. At least a part of the bolt driver unit, which is normally disposed vertically, is pivotable with a horizontal pivotal axis orthogonal to the moving direction of the apparatus. The apparatus also has a flange follower for guiding the bolt driver unit. At least a part of the flange follower, which includes a roller having a vertical rotating axis, is pivotable about a vertical rotational axis. The rotational axis of the roller is offset toward the moving direction of the apparatus with respect to the rotational axis of the pivotable part of the flange follower. The apparatus further has a sensor unit that detects a tilted state of the pivotable part of the bolt driver unit, another sensor that detects a tilted state of the pivotable part of the flange follower, and a video camera for measuring a position of the bolt that is to be driven succeedingly.

There is provided a socket mechanism for rotating a bolt or nut, or like fastening piece, that is used with a vertical type powered bolt/nut driving apparatus. The socket mechanism has a spindle that can be coupled to a drive shaft of the driving apparatus, a socket for engaging with the bolt or nut having a guide at the bottom end thereof for facilitating the object bolt or nut to slip into the socket, a socket holding core having a downwardly tapered mid section, and a generally cylindrically-shaped core holder fixedly attached to the spindle having a bottom opening. The socket is fixedly attached to the low end of the socket holding core. The tapered part of the socket holding core freely lies on the rim of the bottom opening of the core holder in a manner that a lower part of the core and the socket are below the opening and suspending from the core holder. The socket holding core and the spindle are flexibly coupled to each other so that a rotational power is transmitted from the spindle to the core but permitting lateral and angular misalignment therebetween, whereby a reasonable amount of lateral misalignment between the object fastening piece and the drive shaft of the driving apparatus is permitted.
