  • Patent number: 9051966
    Abstract: A linear guide apparatus maintaining a high dust-proof performance over an extended period of time and includes side seal units attached to end parts of a slider in the axial direction. Each side seal unit is provided with: a first seal member, at the slider, arranged in the axial direction of the slider; a second seal member at the outside of the slider in the axial direction; and a lubricating member held between the first and second seal members. The first seal member has first lip parts sliding against the rolling element rolling grooves of the guide rail, while the second seal member has second lip parts sliding against the rolling element rolling grooves. The lubricating member has a first oil-containing member for supplying lubricant to the rolling element rolling grooves. The first and second lip parts are arranged not to come into contact with the first oil-containing member.

  • Patent number: 7556123
    Abstract: In a muffler duct including a duct body and a resonance box, the inside of the duct body and the inside of the resonance box are made to communicate directly with each other not through a cylindrical member. In the partition wall of the resonance box, a gas vent opening portion, which is composed of a gas vent opening having a through hole shape and a gas-permeable member having a gas vent passage of a labyrinth shape for covering said gas vent opening, is formed at a position to confront a communication opening, through which the inside of the duct body and the inside of the resonance box communicate with each other.

  • Patent number: 7540353
    Abstract: A resonator is arranged in an intake system including a pipe section for partitioning an intake port from an intake passage that communicates the intake port with a combustion chamber of an engine, the resonator including: a branch pipe having one end branching to the pipe section and the other end closed so that a silencing chamber is defined therein; and at least one partition wall for partitioning the silencing chamber into at least one pneumatic spring chamber, the partition wall having a natural frequency lower than the frequency of silencing target sound of intake noise propagated from the intake passage.

  • Publication number: 20020183872
    Abstract: A golf site administration system allows elimination of golf site personnel involved in making player reservations, receiving payments, and ordering foodstuffs. A terminal allows a player to request and reserve golf play at a golf site via a communication circuit. A reservation signal is stored in a reservation storing means. The player checks in before play using an input means. A set of check-in information is compared with the stored reservation signal. If the information matches, check-in is performed.

  • Patent number: 5762858
    Abstract: A process for producing a muffler hose having opposite ends, an intermediate portion having a noise-reducing communication hole, and a noise-reducing expansion chamber. The process includes the steps of fitting a protector at the opposite ends of the hose, and disposing the hose and the protectors in a separable blow-molding mold having a jaw; extruding a tubular parison around the hose and the protectors, closing the blow-molding mold, reducing the parison diametrically at two axially-apart positions by the jaw, clamping the parison around the hose at two axially-opposite positions of the hose, the two axially-opposite positions being intervened by the communication hole, and placing the opposite ends of the parison around the protectors; and blowing air into the parison through one of the protectors, and the communication hole of the hose to expand the parison, thereby forming the expansion chamber.

  • Patent number: 5139347
    Abstract: End caps made from synthetic resin are respectively joined to opposite ends of a slider main body of a linear guide apparatus. Each end cap having a substantially inverted U-shape has a joining end surface formed with curved passages to bring ball rolling grooves of the slider main body into communication with each other to form circulating passages. A feed oil groove is also formed in the joining end surface of the end cap to supply lubricating oil to the curved passages. In order to prevent leakage of the lubricating oil from a minute gap between the joining end surfaces of the end cap and the slider main body, a band-shaped protrusion having two parallel ridges is formed along a peripheral edge of the joining end surface of the end cap. The band-shaped protrusion is elastically deformed by a clamping force when the end cap is joined to the slider main body by fixing screws such that the minute gap between the end cap and the slider main body is filled with the deformed band-shaped protrusion.

  • Patent number: 5085522
    Abstract: In a miniature linear guide apparatus, a return guide main body fitting groove which crosses a curved path is formed in a joining end surface of each end cap. A return guide attaching portion fitting groove which extends upwardly from the return guide main body fitting groove is formed in each end cap. A return guide consisting of a return guide main body and a return guide attaching portion formed co-axially with the return guide main body are respectively fitted into the return guide main body fitting groove and the return guide attaching portion fitting groove with a tight fit.

  • Patent number: 4963038
    Abstract: A dust seal attached to each of the end caps of a slider main body is sandwiched at the front and rear surfaces by an outer protector and an inner protector. Each of the outer and inner protectors has a substantially similar shape to the shape of the dust seal. The outer protector is attached to the front surface of the dust seal interposing a spacer to form a gap therebetween to thereby prevent conduction of heat from the outer protector to the dust seal when weld sputters are adhered to the outer protector. The inner protector is closely in contact with the rear surface of the dust seal to form a backup member.

  • Patent number: 4637739
    Abstract: A linear guide device comprises an elongated rail, a slider rectilinearly slidable on the rail, circulation paths each including a rolling path formed between the rail and the slider and a return path formed in the slider, a part of the return path being formed by open grooves and closure members covering the grooves, and a number of balls inserted in the circulation path and rolling during the movement of the slider to thereby smoothen the movement of the slider.
