Patent number: 5333227Abstract: An optical waveguide hose includes a hollow tubular cladding, a fluid core in the cladding, the fluid having a higher index of refraction than the cladding, and sealing plugs mated with opposite end openings of the cladding. In one form, the core fluid is filled in the cladding under positive pressure. In another form, a sheath of a gas barrier material encloses the outer periphery of the cladding. The pressurized fluid core or the gas barrier sheath prevents air from penetrating into the core, allowing the hose to maintain its light transmission function.Type: GrantFiled: April 7, 1993Date of Patent: July 26, 1994Assignee: Bridgestone CorporationInventors: Minoru Ishiharada, Rikuhei Itou, Itsuo Tanuma, Kazuo Naito, Yasuhiko Matsumuro, Takao Aoki, Kiyoshi Koyama

Patent number: 5316739Abstract: Disclosed herein is a method for surface treatment which comprises subjecting an object for surface treatment to an atmospheric pressure plasma while rolling or floating said object in an insulating vessel fed with a prescribed gas and provided on the outside thereof or on both the outside and inside thereof with electrodes for voltage application and grounding, said atmospheric pressure plasma occurring upon application of a voltage to said electrodes. This method permits simple, certain, and uniform surface treatment of any objects in the form of lump or sphere. The surface treatment by the atmospheric pressure plasma does not need the apparatus to be evacuated. Therefore, it can be carried out in a simple apparatus without causing the object for surface treatment to release volatile matters.Disclosed also herein is a method for the surface treatment of vulcanized rubber with an atmospheric pressure plasma in the presence of an oxygen-containing gas and halogen containing gases.Type: GrantFiled: August 19, 1992Date of Patent: May 31, 1994Assignees: Bridgestone Corporation, Satiko Okazaki, Masuhiro KogomaInventors: Masato Yoshikawa, Yukihiro Kusano, Setsuo Akiyama, Kazuo Naito, Satiko Okazaki, Masuhiro Kogoma
