  • Publication number: 20220308206
    Abstract: A vehicle exterior part is configured to be arranged frontward of a millimeter wave radar device with respect to the transmission direction of millimeter waves. The vehicle exterior part includes an ornamental body, a light source that emits light, and a light diffuse reflection member. The light diffuse reflection member is millimeter wave-transmissive and diffuses and reflects light. The ornamental body includes a base and an ornamental layer. The base is millimeter wave-transmissive and diffuses and transmits the light. The ornamental layer is millimeter wave-transmissive and arranged frontward of the base with respect to the transmission direction. The light source, the ornamental body, and the light diffuse reflection member are arranged so that the light emitted from the light source is diffused and reflected by the light diffuse reflection member and directed toward the base.

  • Patent number: 6672962
    Abstract: The gun-shaped controller comprises a controller 1 in the shape of a gun and a trigger lever 7, and a cross-shaped directional key 9 to be operated with a player's finger is arranged in the upper part of a grip 4. By comprising the cross-shaped directional key 9, it is possible to move the character on the screen or the character's visual field with this cross-shaped directional key 9 in addition to the conventional action of shooting targets on the screen. Thus, the gun-shaped controller is compatible with roll-playing games and adventure games.

  • Patent number: 6267074
    Abstract: A plasma treatment system comprises a plasma treatment section in which a plasma treatment space is formed and a plasma producing section in which plasma producing spaces are formed, the plasma producing section being affixed to or formed as a single piece with the plasma treatment section, wherein the plasma producing spaces are located adjacent to and connected to the plasma treatment space and are formed in a dispersed or otherwise distributed fashion. The system is associated with a magnetic circuit for confining electrons within the plasma producing spaces. The system has good controllability over the ratio of plasma constituents. Furthermore, the plasma treatment space is surrounded by a movable wall member to also enhance pressure controllability.

  • Patent number: 6053939
    Abstract: An artificial blood vessel formed into a tube from expanded polytetrafluoroethylene (PTFE), wherein the tube is composed of nodes connected by fibrils creating pores within the wall of the tube. The inner surface of the tube and surfaces of pores comprise a layer extending radially from the inner surface, toward the outer surface of the tube to a depth of 5% to 96%, are chemically treated to make the tube inner surface and pores hydrophilic. Tissue-inducing substances and anti-thrombotic substances are then covalently bonded to the hydrophilic inner surface of the tube and pores. An artificial blood vessel of the invention exhibits a good patency ratio for a long period of time.

  • Patent number: 5355080
    Abstract: Probe pins are mounted on a housing in a manner which deflects the same and induces a preload therein. Upon the pins being brought into contact with a surface, the preload immediately increases the amount of contact pressure which is developed for a given amount of overdrive. In one embodiment the probe pin has both ends secured to the housing. A V-shaped portion is formed in the pin and used as the contact point. The manner in which the probe is secured, bends a portion of the pin proximate the contact point and produces a preload. As the other end is also secured, the preloading is augmented and contact point is prevented from undergoing lateral movement away from the housing on which it is secured.

  • Patent number: 5214375
    Abstract: A test probe assembly including a plurality of electrically conductive probe arms each of which is secured to a substrate and electrically coupled to one of electrically conductive lines provided on the substrate. An intermediate portion of the arm is arranged to be resiliently deformable when a probe point which extends therefrom comes into contact with a terminal of the electronic device under test. A guide is provided on the structure on which the arms are mounted, for guiding the probe point so that movement other than reciprocation is either prevented or arrested. The resilient portion is arranged with respect to the probe point so that generation of motion other than reciprocation of the probe point is attenuated.

  • Patent number: 5084672
    Abstract: A plurality of probe wires are held by a probe supporter having a substantially rectangular cross-section. First, second and third side walls of the supporter, support the probe wires in a manner wherein they are arranged at predetermined intervals in an essentially parallel relationship with each other. The probe wires respectively extend from the first side wall to the second side wall by way of the third side wall. When testing an electronic-device, the third side wall faces a main surface of the device. The third side wall has a groove extending in a direction parallel with the main surface of at least one of the first and second sides wall. Each of the probe wires crosses the groove in a direction perpendicular to the direction along which the groove extends. The portions of the wires which cross the groove are pressed against the tested terminals.
