摘要:
Wafer support shelves (10, 10) are each provided with wafer support projections (A, B1, B2) on which parts of the outer margins of a semiconductor wafer (W) are to be placed. In each case, one of the support projections (A, B1, B2) is provided on the far side of the center position of the semiconductor wafer (W), and two of the support projections are provided on the near side of the center of the semiconductor wafer. By means of this structure, in a state in which a lid body (3) is not attached to a wafer extraction/insertion opening (2), the flexure amount of the semiconductor wafers placed on the support projections of multiple locations in the wafer support shelves can be reduced with a minimal number of projections, so that a hindrance is not created to an operation such as extraction by a robot arm.

A substrate storing container includes: a container body for storing semiconductor wafers; a door that is fitted to the front of the container body; and a locking mechanism locking the door. The locking mechanism includes: a rotary driver that is supported by the door and operated from a cover plate side; and a locking bar that vertically slides as the rotary driver rotates to bring the distal end into, and out of, a locking hollow of the container body. The rotary driver is separated into first and second rotary drivers. The first and second rotary drivers are formed with first and second cam portions, respectively. The first and second cam portions are made to support the proximal end of the locking bar therebetween so that the locking bar can sway in the thickness direction of the door.

A container includes: a container body for storing substrates of semiconductor wafers; a door element detachably fitted to an open front portion of the container body; and a compressively deformable gasket for sealing between the container body and the door element. While a sealing surface for the gasket is formed on an inner periphery of an open front portion of the container body so that the difference between the maximum and minimum of a flatness is less than 0.50 mm, a fitting portion for the gasket is formed in a frame shape. The gasket is formed of a base fitted to the fitting portion; a flexible sealing part extended from the base toward the sealing surface; and a contact portion that is curvedly formed at a distal end of the sealing part and put in press-contact with the sealing surface.

A start-up method of a steam turbine plant including a condenser is disclosed. The condenser includes a tube bundle composed of a number of pipes for condensing an exhaust steam from a steam turbine and a hot well for receiving and storing a condensate therein. The interior of the condenser is airtightly divided into two spaces with a partition therebetween, one of them being an upper space containing the tube bundle and the other one being a lower space containing the hot well. A communication passageway(s) extends between the upper space and the lower space with an isolation valve in the form of a butterfly valve disposed on the communication passageway. At the shut-down of the steam turbine plant, the isolation valve is closed to isolate the upper space from the lower space while the lower space is maintained in vacuum. At the start-up of the steam turbine plant, the isolation valve is opened after the upper space is evacuated, and the upper space is then communicated with the lower space which is maintained still in vacuum.

A substrate storage container includes: a container body molded of molding material in a front open box type for storing substrates; a door element fitted to an opening at the front of the container body; and a compressively deformable gasket for sealing between the container body and the door element. The opening of the container body is projected sidewards and outwards forming a rim portion. A sealing surface for the gasket is formed on an inner surface of the rim portion. The container body is formed with a reinforcing rib directed toward the rim portion. An opposing portion of the reinforcing rib that opposes the rim portion of the container body is reduced in thickness so as to prevent a depression from forming in the sealing surface of the rim portion during molding the container body.

An IC socket includes a cover member vertically movable; a mounting device for placing an IC package; a slide member having a plurality of contact pins inserted therein, horizontally movable; an operating member reciprocating in accordance with the vertical movement of the cover member; and a position control device coming in contact with the slide member to press and move the slide member in a direction perpendicular to the contact surface and to enable the slide member to regain its original position. Thus, the connecting terminals of the IC package are wiped at a moderate contact pressure, and the IC socket having excellent conducting properties can be provided.
