Patent number: 8641286Abstract: A composite bearing member 10 includes: a bearing sliding material 20 whose surface contacts a rotating portion; a bearing base material 30 made of a material different from a material constituting the bearing sliding material 20; and a joining layer 40 joining the bearing sliding material 20 and the bearing base material 30. Further, the bearing sliding material 20 has a sliding layer 50 sliding the rotating portion on a surface. Furthermore, the bearing sliding material 20 has, between the sliding layer 50 and the joining layer 40, a composition graded layer 60 which dispersedly contains the same metal material as a metal material constituting the joining layer 40 and in which a content of the metal material is increased toward the joining layer 40.Type: GrantFiled: November 18, 2009Date of Patent: February 4, 2014Assignee: Kabushiki Kaisha ToshibaInventors: Than Trong Long, Yuuji Hisazato, Satoshi Namba, Kazuma Mukai

Patent number: 6416846Abstract: A composite material has plate 4 having holes and a bonded to a first member to form an intermediate layer, and a second member which is made of a material different from the first member 1 laminated onto the intermediate layer 2 while charging a portion of the second member 5 into the holes 3 of the intermediate layer 5 to form a composite material 6. The holes 3 of the plate 4 which forms the intermediate layer 2 have a shape in such that the charged second member exerts a resisting force against a tensile stress applied in a direction perpendicular to the surface of the first member 1, e.g., a shape having a first hole opened on the side of the second member and a second hole communicated with the first hole and having a space not overlapped with the first hole, or a shape that an opened area on the side of the second member is smaller than that on the side of the first member.Type: GrantFiled: May 16, 1997Date of Patent: July 9, 2002Assignee: Kabushiki Kaisha ToshibaInventor: Than Trong Long
