Abstract

A tubular vibration-damping device including an inner shaft member and an outer tube member connected by a main rubber elastic body. The outer tube member is configured to be slidably inserted in an attachment tube in an axial direction, and is circumferentially divided so as to be radially deformable or displaceable. A pair of tighteners are disposed on axially opposite sides of the main rubber elastic body. The main rubber elastic body is fastened to an inner circumferential surface of the outer tube member. An adjustment elastic body against which the tighteners are pressed is integrally formed with axially opposite side portions of the main rubber elastic body. Sliding resistance in the axial direction between an outer circumferential surface of the outer tube member and an inner circumferential surface of the attachment tube is settable depending on a pressing force of the tighteners against the adjustment elastic body.

A resin connector (10) includes a tubular connector main body portion (11) which is formed to contain a reinforcing filler in a main portion base material resin, and a tubular connector end portion (12) which is formed of a end portion base material resin without containing the reinforcing filler or containing the reinforcing filler at a lower proportion than the connector main body portion (11) and is joined to the connector main body portion (11) to constitute a tubular end portion. The resin tube (20) is formed of a material having a higher absorption rate of a laser beam than the connector end portion (12) and is fitted to the connector end portion (12) to be welded to an inner peripheral surface or an outer peripheral surface of the connector end portion (12) and not to be welded to the connector main body portion (11).

Abstract

A rubber kneading method according to the present invention comprises: a first step for blending and kneading a raw material rubber of a reference lot and a secondary material at a specific compositional makeup to prepare a reference rubber composition and measuring a spring characteristic of a reference rubber crosslinked product which is obtained by crosslinking the reference rubber composition; a second step for blending and kneading a raw material rubber of a target lot and a secondary material at the same specific compositional makeup as in the first step to prepare a target rubber composition and measuring a spring characteristic of a target rubber crosslinked product which is obtained by crosslinking the target rubber composition; and a third step for comparing the spring characteristic of the target rubber crosslinked product with the spring characteristic of the reference rubber crosslinked product and setting a blending condition and/or a kneading condition to be employed when the raw material rubber of the target lot is to be kneaded at a product compositional makeup. Under the condition(s) set in the third step, the raw material rubber of the target lot is kneaded at the product compositional makeup to obtain a product rubber composition which has little variation in spring characteristic.

Abstract

A method for kneading rubber has a first step of preparing a reference rubber composition and measuring a spring property of reference crosslinked rubber obtained by crosslinking the reference rubber composition, a second step of preparing a target rubber composition and measuring a spring property of target crosslinked rubber obtained by crosslinking the target rubber composition, and a third step of comparing the spring property of the target crosslinked rubber with the spring property of the reference crosslinked rubber to set one or more of a compounding condition and a squeezing condition that is adopted in the case of kneading the target lot of the raw rubber in a product composition.

Abstract

The present invention solves problems inherent in surface pressure sensor sheets of conventional structures, such as a drop in detection accuracy under specific conditions. A surface pressure sensor sheet 12 comprises a plurality of detection units 68 having a shape which elastically deforms in response to pressure applied from outside, the detection units 68 each having a first electrode 24 and a second electrode 26 arranged opposing each other so as to electrically detect pressure. In at least one of the plurality of detection units 68, at least one of the first electrode 24 and the second electrode 26 is provided with a reinforcing material 84 that suppresses local deformations of the detection unit 68 and that is positioned on the outer surface side opposite the inner surface side where the first electrode 24 and the second electrode 26 oppose each other.
