Abstract: In a fluid pressure apparatus, a packing is constituted from an annular seal member made of an elastic rubber material, and support rings made of a material possessing low friction, which are mounted on an outer circumference of the seal member. The seal member includes, on an outer circumference thereof, a sealing projection, shoulder portions formed on both sides of the sealing projection, and concave grooves interposed between the shoulder portions and the sealing projection. The support rings include support surfaces on outer circumferences thereof, and engagement projections on inner circumferences thereof, such that by engagement of the projections in the concave grooves, the support rings are mounted on the seal member so as to surround outer circumferences of the shoulder portions.

Abstract: In a fluid pressure apparatus, a packing includes an annular seal member made of an elastic material, and support rings made of a low-friction material, which are mounted on an outer circumference of the seal member. The seal member includes, on an outer circumference thereof, a sealing projection that contacts an inner surface of the slide hole. The support rings are disposed on both sides of the sealing projection, and protrude beyond the seal member in the axial direction. Outer circumferential surfaces of the support rings always contact the inner circumferential surface of the slide hole. When a transverse load does not act on a piston as a partitioning member, the inner circumferential surfaces of the support rings do not contact the outer circumference of the piston. When a transverse load acts on the piston, the inner circumferential surfaces of the support rings contact the outer circumference of the piston.

Abstract: A fluid pressure apparatus includes a piston, and a packing provided on an outer circumference of the piston. The packing includes a support ring made of a low-friction material, and a ring-shaped seal member mounted to the support ring. When at least a certain amount of transverse load acts on the piston, an outer circumferential surface of the support ring abuts against an inner circumferential surface of the slide hole, whereby the piston is prevented from contacting with the inner circumferential surface of the slide hole.

Abstract: A cylinder tube of a cylinder has an outer periphery, as taken in the circumferential direction thereof but excepting the upright surface thereof, comprising: surfaces curved convexly outward, and first to third chamfered portions, and a casing of a position detecting sensor to be mounted on the cylinder has an outer periphery formed of surfaces curved convexly outward and a chamfered portion, thereby it is possible to prevent a liquid from being trapped on the outer surface for avoiding the sanitary problem.

Abstract: Disclosed is a semiconductor integrated circuit device equipped with a buffer portion which includes a pair of an input buffer portion and an output buffer portion. When an input circuit equipped with an input protection circuit is formed at the input buffer portion, circuit elements for an output circuit disposed at the output buffer portion are used in order to constitute the input protection circuit.

Abstract: A semiconductor integrated circuit device is disclosed. The circuit device uses modified (m+n) input cells, each equipped with high load driving functional elements disposed at the periphery of the cell, and having n signal input terminal(s) in addition to m normal signal input terminals that are incorporated in the cell.

Abstract: A semiconductor integrated circuit device is provided which is equipped with a buffer portion which includes a pair of an input buffer portion and an output buffer portion. When an input circuit equipped with an input protection circuit is formed at the input buffer portion, circuit elements for an output circuit disposed at the corresponding output buffer portion are used in order to constitute the input protection circuit.

When an input circuit equipped with an input protection circuit is formed at the corresponding input buffer portion, circuit elements for an output circuit disposed at the output buffer portion are used in order to constitute the input protection circuit. Therefore, the circuit elements of the corresponding output buffer portion, which normally would be unused, are utilized to provide an important circuit function.
