  • Patent number: 6385815
    Abstract: In a frictional hinge device a support block 20 is molded in a synthetic resin around the metallic shaft 10 so that the support block 20 is rotatably supported by the metallic shaft 10. The support block 20 is held at any angles by a surface friction resistance between the support block 20 and the metallic shaft 10. The synthetic resin has a modulus of bending elasticity, a changing rate of which is up to 30% at an operating temperature ranging from −20 to 80° C. The support block 20 tightly engages with the metallic shaft 10 due to a residual stress appeared between the support block 20 and the metallic shaft 10 when cooling the synthetic resin to shrink. Due to the smaller changing rate of the modulus of bending elasticity, the surface friction resistance becomes stable between the support block 20 and the metallic shaft 10 under normal ambient temperature with the least amount of friction.

  • Patent number: 6386593
    Abstract: A dual-plane sealing configuration for a fluid-tight conduit connection that incorporates additional sealing areas and minimizes assembly misalignment. A gasket is mounted around a conduit, sandwiched between an end-form block and a receiver, and compressed therebetween using a fastener fitted through the end-form block and threaded into the receiver. The gasket has a formed pilot that pilots around the conduit and is sandwiched between the conduit and a chamfer in the receiver to establish a secondary seal. The gasket incorporates features such as a fold-over tab and a non-uniform embossment to counteract the cantilever behavior of the conduit connection.

  • Patent number: 6375164
    Abstract: A double-tape pedestrian traffic control device including a hollow, one piece post having an open upper end, and at least one slot in the post about midway between its ends. A first cassette is mounted on the upper end of the post and a second cassette is located within the post at the level of the slot. Each cassette contains a tape wound on a spool, the spool being spring-biased to rotate in a direction which winds the tape on to the spool. The tape of each cassette is extendable from that cassette in a direction generally perpendicular to the vertical axis of the post, the tape of the second cassette extending through the slot in the post. The diameter of the second cassette, along its entire axial length, is smaller than the internal diameter of the post, so that the second cassette can be inserted into the open upper end of the post and moved to its location between the ends of the post.

  • Patent number: 6367848
    Abstract: Past applications have found that a joint becomes damaged due to the high loading and vibration loads in which it encounters during operation. The counterbored joint utilizes the flexible shim that is larger than the body receiving bore. A undercut is machined into the body receiving bore which allows for the flexible shim to be placed within the body receiving bore between the first and second step surfaces. The first step surface is parallel to the second step surface which distributes stresses uniformly and helps in sealing. The principal use is for a cylinder liner joint, however any joint that is highly loaded or encounters vibrational loads will benefit from this invention. For example, a hydraulic joint that utilizes a piston in operation may be remanufactured with this invention.

  • Patent number: 6352382
    Abstract: The present invention is a corner molding particularly useful in the construction of juvenile furniture. The corner molding has an elongate body with an interior, a first rounded side, and a second side opposite the rounded side, with a pair of acutely V-shaped channels extending along the length of the body. The first rounded side and each of the V-shaped channels preferably form a pair of rounded outer edges therebetween. Each V-shaped channel receives a substantially rectangular edge of a planar member to form a rounded corner such that the planar members are held substantially perpendicular relative to each other, with smooth joints between the outer edges and planar members. The present invention further provides a method of attaching a pair of planar members within acutely V-shaped channels of a corner molding to thereby provide a rounded corner having smooth joints between the planar members and the corner molding.

  • Patent number: 6341405
    Abstract: A clamp that is locked to a body panel by inserting a flexible locking blade portion thereof into an installing hole and utilizing a return of the locking blade portion to an original state thereof when the locking blade portion exceeds the installing hole. The clamp comprises a resinous material having Rockwell hardness at 100 or more and 150 or less and molded by one-piece molding. When the clamp fits on the body panel, a fit-on sound and consciousness of a return of the locking blade portion to the original state are generated. In the clamp, an increase of an insertion force that is generated by increasing a hardness of the clamp is offset by increasing a height of a projection portion with respect to a substrate portion and decreasing an angle of the locking blade portion formed by turning down a front end of the projection portion to decrease a projection amount of the locking blade portion in a lateral direction thereof.

  • Patent number: 6338590
    Abstract: A fitting is provided with surface corrosion protection which is obtained by firstly hot galvanizing the fitting and subsequently dipping it into a molten, eutectic alloy of zinc and approximately 5% aluminum before swaging it to a wire rope. In order to prevent the wire rope from sliding in the channel, the surface corrosion protection is deposited substantially only on the outer surfaces of the fitting, the channel receiving the wire rope being kept at least substantially free from the corrosion protection.
