A substrate processing apparatus comprises a chamber. The chamber includes a container and an upper lid for closing an upper opening of the container. On the upper side of the chamber, an elevator for vertically moving the upper lid is disposed integrally with the chamber.

Substrate processing apparatus and maintenance method therefor

A stage base comprises a base body, an elevator, and a shifter. The base body has a bottom face facing a reference surface. The elevator is attached to the base body and operative to move the base body in a vertical direction with respect to the reference surface. The shifter is attached to the elevator. The shifter enables the base body to move along the reference surface.

Stage base, substrate processing apparatus, and maintenance method for stage

A method of and an apparatus for rolling a rod as a starting material and producing a wire of 5 mm or smaller diameter, the method and apparatus using a continuous rolling mill comprising a plurality of round-grooved four-roll stands arranged in tandem, wherein the grooved four-roll is displaced between adjacent rolling stands by 45 degrees relative to each other around the pass line and the center-to-center distance between adjacent rolling stands measured in the pass line direction is not greater than 50 times the diameter of the rod. The front end portion of the rod is fed at slow speed into the continuous rolling mill, the front end portion being guided by a front pipe to the center of the round groove, and the front end portion is wound on a coiler. After that, the rotation speed of the grooved rolls in each rolling stand is so set as to prevent slack in the rod passing through the continuous rolling mill, and the rod is rolled at high speed, without causing the rod to touch the leading pipe, to produce a wire. Each of the rolling stands that constitute the continuous rolling mill is movable in a direction perpendicular to the pass line, each rolling stand being moved for connection to or disconnection from the driving source.

Method of and an apparatus for producing wire

The present invention is to provide a compact roll stand apparatus, particularly of four-roll type, comprising both a roll parting adjustment device and an all-roll drive device. Further in detail, a roll stand apparatus comprising: a plurality of grooved rolls arranged radially, with substantially same degree intervals, from the pass line along which material bars and rods are driven, and whose rotational axes lie on a plane; eccentric shafts each rotatably supporting each of said grooved rolls; a device for simultaneously rotating said eccentric shafts and also simultaneously adjusting radial distances from said pass line to the rotation axes of said grooved rolls; driven gears each mounted concentric with the rotation shaft of each of said grooved rolls so as to rotate integrally with each of said grooved rolls; driving gears whose rotation axes lie on a plane apart, in the direction of said pass line, from said plane where the axes of said grooved rolls lie, and which engage with said driven gears; and a drive device for simultaneously rotating said driving gears.
