Abstract: A hinge, wherein, inter alia, intrusion of foreign matter in a contacting portion of a slide member and a cam member and resulting adhesion of an oil provided in the cam member to the foreign matter is reliability prevented from the closed state to the open state of a second wing member. The hinge is provided with an oil fence disposed on the outside close to the contacting portion of the cam member and slide member, the oil fence preventing, from the closed slate to the open state of the second wing member, foreign matter front intruding into the contacting portion of the slide member and cant member from the outside of the slide member and cant member.

Abstract: The present invention addresses the problem of providing a one-way clutch and a one-way clutch-equipped rotating damper device with which it is possible to achieve size reduction. A pawl portion of a slide member comprises a withdrawal surface and an engaging surface. When a gear member rotates toward one side, as inner teeth and the withdrawal surface abut each other, the slide member slides in a sliding direction and the pawl portion is withdrawn from the inner teeth, whereby the gear member rotates independently of a rotor shaft. When the gear member rotates toward the other side as the inner teeth and the engaging surface abut each other, the inner teeth and the engaging surface become engaged, whereby the gear member and the rotor shaft rotate integrally.

Abstract: A damper is provided which can more reliably prevent malfunction and breakdown and which enables efficiently performing repair and inspection operations.

Abstract: Provided are a one-way clutch and a rotary damper device equipped with the one-way clutch, in which size reduction can be achieved. A claw of a slide member has a retreat surface that abuts against an internal tooth of an outer member when the outer member turns toward one side with respect to an inner member and an engagement surface that abuts against the internal tooth when the outer member turns toward the other side with respect to the inner member. When the internal tooth and the retreat surface abut against each other, the slide member slides in a sliding direction, thus causing the claw to retreat from the internal tooth, and the outer member turns independently of the inner member. When the internal tooth and the engagement surface abut against each other, the internal tooth and the engagement surface are engaged, and the outer member and the inner member integrally turn.

Abstract: Provided is a hinge that can prevent a defect, a failure, or the like with greater certainty, and enables inspection and repair work to be efficiently carried out. A hinge comprises a first wing member that is connected to a first connection object and a second wing member that is connected to a second connection object. The hinge rotatably connects the second connection object to the first connection object. The hinge comprises a sensor that detects a change inside the hinge or in a prescribed external environment change in the external environment detected by the sensor to the outside via a sensor that detects a prescribed component constituting an odor, a gas sensor that detects a prescribed gas, a dust sensor that detects the amount of dust, and a illumination sensor that detects brightness.

Abstract: A damper is provided which can more reliably prevent malfunction and breakdown and which enables efficiently performing repair and inspection operations.

Abstract: A multi-feed detection device is provided with: a base; an arm rotatably supported on the base; a magnet affixed to the arm; a Hall element which is affixed to the base, and which outputs an electric signal corresponding to the strength of the magnetic field; a differentiation circuit which outputs a voltage corresponding to the differential value of the output of the Hall element; and an integration circuit which outputs a voltage corresponding to the integral value of the output of the differentiation circuit. The arm applies a force against a conveyance path by way of a spring. One or more sheets of paper conveyed on the conveyance path raise the arm, separating the magnet from the Hall element. Accordingly, the output of the integration circuit varies, and the number of sheets of paper is detected on the basis of this variation.
