Patent number: 7176269Abstract: The curable composition of the present invention contains (A1) a silyl-containing ethylene/?-olefin/non-conjugated polyene random copolymer rubber which has a structural unit derived from a norbornene compound as the non-conjugated polyene with at least one specific vinyl group at the terminal and contains a specific hydrolyzable silyl group, and (B) a compound, other than the rubber (A1), having a hydroxyl group and/or a hydrolyzable group, e.g., (B1) a compound having a silanol group and/or a compound which can react with moisture to form a compound having a silanol group in the molecule. This compound improves elongation of the cured product and residual surface tackiness, and, at the same time, is high in curing speed and capable of giving the cured product of high resistance to weather. It is suitable for, e.g., adhesives, tackifiers, paints, sealants, waterproof materials, spray materials, shaping materials and casting rubber materials.Type: GrantFiled: July 24, 2001Date of Patent: February 13, 2007Assignee: Mitsui Chemicals, Inc.Inventors: Takashi Hakuta, Masaaki Kawasaki, Yoshiharu Kikuchi, Mitsunao Arino, Mitsuko Nagai, Hiroaki Sakaguchi, Masaki Sugawara, Masao Kishi, Kaoru Ueno, Takashi Abe, Michio Sekine

Patent number: 6981919Abstract: A power train includes a driving shaft and a follower shaft connecting to the driving shaft by way of a first joint. The follower shaft is adapted to slide relative to the driving shaft in an axial direction. The follower shaft includes: a holder shaped substantially into a cylinder, and a tubular shaft section coupled with the holder in the axial direction. The first joint includes a member defining an outer diameter. The holder holds therein the member of the first joint. The tubular shaft section coupled with the holder in the axial direction causes an inner curl to a second joint coupling the holder and the tubular shaft section. The inner curl defines an inner diameter greater than the outer diameter of the member of the first joint.Type: GrantFiled: November 15, 2002Date of Patent: January 3, 2006Assignee: Hitachi, Ltd.Inventors: Kenichi Sugiyama, Toshiyuki Masuda, Masao Kishi

Patent number: 6913105Abstract: A shock-absorbing mechanism for a power-transmission device includes a cylindrical driven-side shaft coupled to the driving-side shaft through a constant-velocity joint to be axially relatively slidable with respect to the driving-side shaft, a center bearing for rotatably supporting the driving-side shaft to the vehicle body, and a labyrinth mechanism for sealing the inside of the center bearing. An end of the driven-side shaft on the side of the driving-side shaft is disposed axially opposite to the labyrinth mechanism. When the two shafts are slid in the direction to approach each other by an axial load input thereto, the end of the driven-side shaft collides axially with the labyrinth mechanism.Type: GrantFiled: April 1, 2003Date of Patent: July 5, 2005Assignee: Hitachi, Ltd.Inventors: Toshiyuki Masuda, Masao Sakamoto, Shinichi Kondo, Masao Kishi

Patent number: 5303081Abstract: It is profitable to oscillate a beam on objects when a high power CO.sub.2 laser beam or a high power YAG laser beam welds or anneals the objects. In order to let a laser beam scan, a device for reciprocating a lens or a device for rotating two mirrors synchronously has been proposed. These devices suffer from the difficulty of cooling. Prior devices are not applicable to a high power laser. A parallel laser beam is first reflected by a parabolic mirror. Then a mirror which is reciprocally swaying by a galvanometer reflects the beam toward the objects. A water inlet and an outlet are mounted on a rear surface of the swaying mirror. Cooling water is carried out through coiled tubes. Excellent heat diffusion prevents the galvanometer from malfunction.Type: GrantFiled: May 12, 1993Date of Patent: April 12, 1994Assignees: Sumitomo Electric Industries, Ltd., Toyota Jidosha Kabushiki KaishaInventors: Kazuhiro Totsuka, Akio Asai, Hideki Kamogawa, Masao Kishi
