  • Patent number: 7927137
    Abstract: The coaxial cable connector includes a connector body, a securing ring, and a holder. The connector body includes an insertion section, a flange section, and a fitting section. The insertion section is insertable to between an insulation member and a braided conductor of the coaxial cable. The flange section is provided around the insertion section. The fitting section is rotatably provided at the insertion section on an opposite side of the coaxial cable. The securing ring is used to crimp and fix the coaxial cable to the connector body. The holder positions the securing ring around the insertion section of the connector body.

  • Patent number: 7012496
    Abstract: The invention provides a noise elimination device that can be installed easily on a coaxial cable and that can effectively eliminate noise from both the center conductor and the outer conductor. Coaxial connectors 2 and 3 are provided on both ends of a tube-shaped housing 1 made of an insulator, and a coil made by winding a coaxial cable of thin diameter is around an open magnetic ferrite core is disposed inside the housing 1 and connected to the connectors 2 and 3 at the two ends. The earth-side connector thickness of the outer conductor of the coaxial cable and the connector as well as all earth-side conductors, such as shield members 7 connecting the connectors with the outer conductors of the coaxial cable, is at least 0.1 mm.

  • Patent number: 5405681
    Abstract: A synthetic resin decorative material including an antistatic layer containing an electrically conductive film formed on a surface thereof without changing the color, design and pattern of the decorative material. The synthetic resin may be a synthetic resin decorative sheet/plate. The antistatic function of the antistatic layer is improved such that occurrence of cracks in the antistatic layer can be prevented when the decorative material having the antistatic layer is thermally molded. To prepare the decorative material, a transfer sheet is pressed while being heated onto a surface of a synthetic resin decorative base material including a synthetic resin sheet or plate. To prepare the transfer sheet, electrically conductive paint containing an electrically conductive matter formed by coating inorganic fine powder having a refractive index of 1.4 to 1.7 with an electrically conductive tin oxide is applied onto a 1 to 5 .mu.

  • Patent number: 4227442
    Abstract: A cylinder control device of a hydraulic cylinder apparatus including a two-position, directional control valve having a pilot chamber for effecting control of reversal of the direction of movement of a piston, and a control valve movable between two positions depending on the pressure of working fluid in a conduit on the pump side. The control valve is mounted in a passage connecting the pilot chamber of the two-position, directional control valve to a valve means capable of bringing the pilot chamber into communication with conduit on the fluid discharging tank side when the cylinder piston reaches a predetermined position in its rearward stroke. Alternatively, the control valve may be mounted in a passage connecting the pilot chamber of the two-position, directional control valve to another valve means capable of bringing the pilot chamber into communication with the conduit on the pump side when the cylinder piston reaches the end of its forward stroke.
