IPC: G11B21/02
Filed: 1993-12-03
Abstract: PURPOSE:To obtain a means for stopping runaway-of a carriage which is not easily deformed because of an intensive rigidity and does not transfer a thermal deformation to a rail housing even if a line expansion coefficient is different. CONSTITUTION:A rail housing 11 and a stopper 12 as a stopping means are coupled through rubber rings 16A, 16B as the viscous and elastic material having a strong rigidity in the moving direction of a carriage 7 and a degree of freedom in the orthogonal direction and thereby the stopper 12 can be expanded freely for temperature change.

Title: Operation of steam flow control valve of steam turbine and its device
Inventor: ABE MASAHARU
IPC: F01D17/10
Filed: 1988-12-02
Abstract: PURPOSE:To permit the test of a steam flow control valve in an operating state with easy handling by controlling the steam flow control valve with the opening varied within the range equivalent to saturation flow rate of the curve of the opening of the steam flow control valve to steam flow rate. CONSTITUTION:The phenomenon that a steam flow control valve (V) is agglutinated to disable open-and-close operation occurs mainly in between a valve rod 10 and a valve rod guide 14 exposed to high-temperature steam. To dissolve such an agglutinated condition, configuration is so made that the valve rod 10 can be stroked without varying a steam flow passing through the valve (V) when test operation is performed to stroke the valve rod 10 during load run. That is, a cam shaft 5 rotated by the action of a cylinder 1 via a rack 6 and a pinion 3 is mounted with a cam 7, and via a lever 11 associated with this cam 7 the valve rod 10 is elevated up and down. The cam 7 is formed in the shape of varying the opening of the valve within the range equivalent to saturation flow rate of the curve of the opening of the steam flow control valve (V) to steam flow rate.

Title: Manufacture of wadding material for vehicle seat
Inventor: SUEYOSHI KENJI
IPC: B68G3/06
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To provide a wadding material in prescribed thickness with large restoring force against pressure in the thickness direction by heat-setting crimp fiber filament under a temperature lower than that of primary crimp to crimp the crimped fiber filament again. SOLUTION: A fiber web 1 is guided into a heating zone 10 where hot wind at 160-180 deg.C, which is a temperature lower than the melting point of crimped fiber filament 2 but can generates crimp, is flowing in the vertical direction by a conveyor 10a. The hot wind is passed through fiber web 1 in the thickness direction. The heat treatment is carried out to generate primary crimp of the crimped fiber filament to constitute the fiber web 1. Since needle punching is not applied yet to the fiber web, fiber filament is not entangled with each other. Since the crimping tendency of the crimped fiber filament 2 is never limited, the filament 2 is brought into a sufficiently crimped condition. It is important for improving the cushioning performance to carry out heat treatment before needle punching.

Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To provide a flexible memory system. SOLUTION: Computer instructions and picture data are stored in the same semiconductor memory if necessary. In order to efficiently use a memory subsystem where both calculation instructions and picture data are stored, a virtual memory control process is used which efficiently pages picture data and computer instructions from a main memory to a large-capacity storage device like a hard disk drive. Therefore, if more space is required to store the computer instructions or to store picture data, the virtual space memory system dynamically assigns memory volumes to picture data and computer instructions, and various kinds of data are paged between the semiconductor memory of the digital copying machine and the large-capacity storage device.
