Title: Method of preventive discoloration of polyurethane
Inventor: TODA HIDEAKI
IPC: B65D81/24
Filed: 1993-09-27
Abstract: PURPOSE:To prevent discoloration of polyurethane, by containing polyurethane processed goods or the like made of polyurethane raw fabric or polyurethane raw materials into a bag having a perticular permeability of oxygen gas. CONSTITUTION:A polyurethane raw material of polyurethane film, tape or the like or polyurethane processed goods or polyurethane package 1 made of polyurethane raw material, is contained inside a bag 2 having 4500ml/m<2>.24 hr.atm or less in the permeability of oxygen gas. When a polyurethane film is packed or sealed with heat by an external material like various kinds of plastic films, laminate articles or kraft paper, the discoloration of the polyurethane in the inside is affected by the permeability of oxygen. If polyurethane film is wrapped by a bag having 4500ml/m<2>.24hr.atm or less in the permeability, it has been found according to test results that the polyurethane hardly decolors. Accordingly, polyurethane raw materials, paper diapers, disposable wear made by joining non-woven clothes, gloves, etc., can be reserved for a long time.

Title: Wafer-cassette housing box
Inventor: ISOTANI MASASHI
IPC: H01L21/70
Filed: 1989-10-06
Abstract: PURPOSE:To prevent dust particles from being produced by a vibration by setting a wafer-cassette housing box as an inclination type during a transport operation and to easily take out a wafer cassette by setting the box as a horizontal type during a transfer operation by a method wherein a bottom plate of the box can be turned so as to be tilted freely up to a definite angle. CONSTITUTION:A bottom plate 1 of a wafer-cassette housing box 4 is installed in such a way that it can be turned so as to be tilted freely up to a definite angle. When a wafer cassette is conveyed, a bottom-plate support 3 is fixed to a stand 7 and the bottom plate 1 is tilted; also the cassette is tilted to restrain dust particles from being produced by a vibration of a wafer. When the cassette is transferred, the bottom-plate support 3 is removed and the bottom plate 1 is set horizontally; then, the cassette is set horizontally; the cassette can be taken out without remodeling a transfer apparatus. Thereby, the box can be used as an inclination type and a horizontal type by a simple constitution.

Title: Exclusive control method
Inventor: SAKAI NAOFUMI
IPC: G06F9/46
Filed: 1988-10-19
Abstract: PURPOSE:To shorten the time during which a desired process is started after a page lock state is released by omitting the repetition of an undesired locking process and the execution of the post-processes carried out for each page release. CONSTITUTION:A gathering of pages where the task Ti is locked at a time point (t) is referred to as Tip(t) together with a gathering of the pages waiting for release of their lock states referred to as Tiw(t) respectively. Under such conditions, ti requests the lock of plural pages at one time at t0 and the pages P1-Pn wait for their release. In case the task of an equation I releases the lock to Pk at t0<t1, Tj does not post T1 in the case of Tiw(t)-Pknot equal to phi and then posts T1 only in the case of Tiw(t)-Pk=phi. When a deadlock occurs, this method is applied after a known releasing process. Thus plural page lock requests are accepted at one time with the reduced overhead. These lock requests can be processed by a exclusive control method.

IPC: B60G7/04
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To provide a suspension device for a vehicle such as excellent comfortableness to ride in can be obtained at empty car time and loading car time. SOLUTION: In a suspension device 10 having a lower arm 11 and an upper arm 12, a horizontal leaf spring 30 and a compression coil spring 40 are arranged. A rubber spring 50 is arranged between an intermediate part and a car body side member 15 up to reaching a tip part 33 from a center part of the leaf spring 30. At empty car time, the rubber spring 50 separates from the leaf spring 30, and only the leaf spring 30 and the coil spring 40 can deflect. When a load is small at loading car time, since the rubber spring 50 is compressed in an elastically deformable range by the leaf spring 30, a spring constant increases. The rubber spring 50 is completely crushed at large load time, and since the leaf spring 30 can deflect in a short span reaching the tip part 33 with the rubber spring 50 as a fulcrum, a spring constant increases further.

Title: Accumulating device for plate-like object
Inventor: YAMAMOTO CHISATO
IPC: B65H29/44
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To prevent damage such as breakage from being caused to a tip of a plate-like object when it slides down a movable chute and stops. SOLUTION: A roller 54, which is installed in a movable chute, when it is touched by a PS plate sliding down the movable chute, rotates following the sliding-down PS-plate. Since a torsion coil spring 58 is interposed between the roller 54 and a bracket 56, as the roller 54 rotates following the sliding-down PS-plate, the energizing force is increased, thereby enlarging the rotational resistance. With this contrivance, the dropping/sliding-down speed of the PS- plate, which is in contact with the roller 54, is reduced gradually.
