Abstract: A vibration control mechanism 50 is interposed between a ball bearing 8 and a support section 2a of a base 2. The vibration control mechanism 50 is provided with a plurality of laminated sliding members 51, 52 and an elastic body 53. The vibration control mechanism 50 is provided with the plurality of sliding members 51, 52, and therefore has a plurality of sliding surfaces. As a result, it is possible to enhance a vibration control effect.

Abstract: [Problem] To provide a high-stretchability/contractibility stretchable contractible wiring sheet that can be produced easily at low costs, has high flexibility, high durability, and high conformity to external force, and undergoes small resistance value change along with stretching and contracting and a producing method and apparatus for the same, and a stretchable contractible touch sensor sheet. [Solution] A stretchable contractible wiring sheet of the present invention includes: a stretchable contractible first elastomer sheet 1a; a stretchable contractible second elastomer sheet 1b facing and bonded on the first elastomer sheet 1a; and a lead 2 interposed between the first elastomer sheet 1a and the second elastomer sheet 1b in a state of having a wavy shape periodically curving in-plane in facing surfaces of the first elastomer sheet 1a and the second elastomer sheet 1b and being biased in a direction to restore to a rod-like shape from the wavy shape during unloading.

Abstract: A vacuum pump has an exhaust portion in which rotating blade portions and stationary blade portions are laminated in multiple stages. Each of the plurality of stator blades in one stage of the stationary blade portion is three-dimensionally connected to the stationary blade portion main body by an inner circumferential side support portion on the inner circumferential end side, and three-dimensionally connected to the stationary blade portion main body by an outer circumferential side support portion on the outer circumferential end side, and a cutout is provided in ag circumferential front end of the outer circumferential side support portion.

Abstract: A vacuum pump comprises an exhaust portion having a plurality of rotating blade portions arranged in multiple stages, each of the rotating blade portions having a plurality of rotor blades, and a plurality of stationary blade portions arranged between the rotating blade portions, in which outer circumferential rims are supported via spacers, each of the stationary blade portions having a plurality of stator blades. In at least one stationary blade portion among the plurality of stationary blade portions, a blade height on the inner circumferential side of the plurality of stator blades provided in the stationary blade portion is set to be smaller than a blade height on the outer circumferential side, and the stationary blade portion is supported by the spacers in such a manner that the inner circumferential side of the stationary blade portion is floated up toward an intake port side.

Abstract: Disclosed are metallic wire with high surface quality and low-cost suitable for use as material for grip rings and a producing method and apparatus thereof. Metallic wire 34 deformed in a coil shape is passed through a shape correction unit 14 so as to straighten it. Furthermore, while upper and lower pressing rollers 19, 20, 26, 27 prevent the metallic wire 34 from warping upwardly and downwardly, wedge-shaped grooves are continuously formed on the metallic wire 34 by means of a first cutting roller 21 and a second cutting roller 23.
