  • Patent number: 8657084
    Abstract: The present invention provides a rotary damper in which both yields and braking characteristics can be enhanced. The rotary damper of the invention includes a valve mechanism which comprises an operating chamber 7 through which fluid can pass, a valve body 8 which forwardly moves from a natural state position when the valve body 8 receives fluid pressure and which can forwardly moves in the operating chamber 7, and a first spring 9 capable of giving a resistance to the forward movement of the valve body 8. The valve mechanism can reduce a flow rate of fluid which passes through the operating chamber 7 by a flow path 14 formed between the valve body 8 and a peripheral wall 7a of the operating chamber 7. A reducing amount of fluid can be increased as a moving distance of the valve body 8 which forwardly moves in the operating chamber 7 is increased.

  • Patent number: 7204353
    Abstract: A rotary damper is provided which can include a valve (6) which automatically varies a flow rate of a viscous fluid passing through fluid passages (5a, 5b) in correspondence with variation in load. The valve (6) comprises a leaf spring. The flow rate-adjusting portion (6g) constituting the valve (6) is provided so as not to close the fluid passages (5a, 5b) when no load is applied and bends so that its one surface side projects when no load is applied and becomes deformed in a direction in which the fluid passage (5b) is closed when receiving pressure of the viscous fluid on its one surface side. The flow rate of the viscous fluid passing through the fluid passage (5b) is adjusted depending on a degree of deformation of the flow rate-adjusting portion (6g) corresponding to magnitude of pressure of the viscous fluid applied to one surface side of the flow rate-adjusting portion (6g).

  • Publication number: 20050205370
    Abstract: An object of the invention is to provide a rotary damper which can individually control two controlled subjects independently rotatable with each other by utilizing both a viscous resistance by a viscous material and a resistance by a viscous fluid and putting properties thereof to good use. A rotary damper (1A) is provided with first and second chambers (4, 5) which are separated by a partition wall (3), a rotor (6) which is rotatably arranged within the first chamber (4), a viscous material (7) which is filled in a slight gap between the rotor (6) and a slidable contact surface slidably contacted with the rotor (6), a viscous fluid (11) which is filled in the second chamber (5), and a vane (12) which is swingably arranged within the second chamber (5) filled with the viscous fluid (11).

  • Patent number: 5864737
    Abstract: An apparatus which forms a discharge electric field in order to discharge an object. The apparatus includes an electrode member facing and separated by a preselected gap from the object, and a power source which applies a discharge voltage to the electrode member to thereby cause discharge to occur between the object and the electrode member. Further, the electrode member at the gap includes a material selected in association with the gap so that a functional relationship between the discharge voltage and a discharge current caused by the discharge voltage is a continuous function.

  • Patent number: 5165509
    Abstract: A bidirectional retaining clutch capable of stopping rotation of a rotated object such as a revolving shaft of a pivoted cover of a personal computer, a door sheave of a sliding door or the like in one direction at any desired position while keeping it freely rotatable, as well as ensuring free rotation of the rotated object in an opposite direction as desired when torque of a predetermined level or more is applied. An outer cylindrical structure arranged so as to rotated relative to a shaft includes a pair of roller positioning members each provided on an inner surface with roller receiving recesses of an elliptic shape. The rollers which are received in the recesses selectively move in the recesses so as to permit the shaft to be revolved relative to the outer cylindrical structure in one direction while preventing revolution of the shaft in an opposite direction.

  • Patent number: 5100733
    Abstract: If a member made of rubber containing carbon black and a member made of aluminium alloy come into contact with each other under existence of an electrolytic solution, corrosion of the aluminium alloy member would proceed. Such corrosion of the aluminium alloy member can be suppressed by selecting a surface resistivity (surface electric resistivity) of the rubber member at 10.sup.6 .OMEGA. or higher, and more preferably 10.sup.7 .omega. or higher.
