  • Patent number: 8833299
    Abstract: A plasma stream-derived deposited matter formed on an annular rib for droplet capture in a plasma processing apparatus is prevented from falling into a plasma generation portion and causing a short circuit. The annular rib for the droplet capture is divided into multiple rib segments. Thus, from the beginning of the formation of the deposited matter on the annular rib due to the aggregation of the material in the plasma stream, it is possible to reduce the size of the deposited matter. By reducing the size of this deposited matter, when a piece of the deposited matter falls into the plasma generation portion, the piece of the deposited matter gets into a groove portion provided between a cathode and a wall surface of the plasma generation portion, thereby preventing the electrical short circuit between the cathode and the wall surface.

  • Patent number: 8221653
    Abstract: A composition of conductive rubber which does not adhere each other in uncross-linked state is provided to exhibit good workability. The composition of conductive rubber including carbon as conductive additive in a base rubber to be cross-linkable by electron beam radiation includes 5 to 40% by weight of an adhesion inhibitor of uncross-linked rubber into a base rubber which is selected from ethylene ethyl acrylic acid copolymer resin (EEA), ethylene vinyl acetate copolymer resin (EVA), ethylene methyl acrylate copolymer resin (EMA), and ethylene acrylic acid copolymer resin (EAA).

  • Publication number: 20120037504
    Abstract: An object of the present invention is to provide a multiply divided anode wall type plasma generation apparatus, wherein a short circuit between the cathode and the anode is not caused even if deposited matter adhering and depositing on the inner wall of the anode by diffusion plasma detach and fall. Also, an object is to provide a plasma processing apparatus using the same. When the plasma (P) generated between the cathode (2) and the anode (3) is ejected forward from the cathode (2) and diffuses, the diffusing material (41) recrystalizes, adheres, and deposits on the inner wall of an electrode cylindrical body, and detaches and falls as a carbon flake (40). The inner wall of the electrode cylindrical body is multiply divided in the shape of a matrix by means of longitudinal and lateral grooves (37, 38).

  • Patent number: 7216393
    Abstract: The present invention relates to an optical-connector cleaning device, wherein an outer casing has an openable and closable window, through which a cleaning tape for cleaning fiber end surface of the optical connectors is gradually fed. The optical-connector cleaning device according to the invention includes a cassette for integrally holding a reel for feeding unused cleaning tape and a reel for taking up the used cleaning tape, wherein the cassette can be attached to and detached from the outer casing, thus facilitating the replacement of the cleaning tape. Furthermore, in the optical-connector cleaning device according to the invention, a replacement unit including a guide plate for guiding the fiber end surface of the optical connector and a rubber pad serving as a base for the cleaning tape can be detachably disposed at a position corresponding to the window in the outer casing, thus facilitating the cleaning of optical connectors having different shapes.

  • Patent number: 5802754
    Abstract: An identification (ID) plate attachment structure is provided. According to this structure, adhesive agent spreads over not only one face of an attachment portion of an ID plate, but also the opposite face thereof owing to the provision of a plurality of through holes which the attachment portion of formed with. In attaching the ID plate to a mounting boss of a vehicular main component, such as, a transaxle, via a bolt, the pressure exerted by a head of the bolt in the process of tightening the bolt displace the adhesive agent disposed on the one face of the attachment portion to the side on the opposite face thereof via the through holes. Owing to the provision of the adhesive agent, a roughly equal frictional coefficient is obtained between the bolt and the attachment portion and between the attachment portion and the mounting boss and breakage of the ID plate during installation due to bolt tightening is prevented.

  • Patent number: 4883968
    Abstract: An electron cyclotron resonance ion source for an ion implanter. The source includes an ionization chamber surrounded along its length by an electromagnet. A number of extraction electrodes at an output end of the ionization chamber allow positively charged oxygen ions to pass through apertures in the electrodes. The uniformity of the axially aligned magnetic field in the ionization chamber is extended through the extraction electrode by a magnetically permeable electrode and through use of non-magnetically permeable material to mount others of said electrodes.

  • Patent number: 4850163
    Abstract: Steps are formed around the peripheries of respective floor panels, so that wiring channels are formed between the side surfaces of adjacent floor panels when said floor panels are installed. As a result, the laying of power cables and communications cables on the floor surface, which is impossible in the case of conventional free-access floors, is made possible. Furthermore, these wiring channels are covered by wiring covers, thus eliminating any indentations or projections in the floor surface and providing a flat floor surface.
