Straight notches are formed in the outer peripheral surface on both axial sides of each small protrusion to provide elasticity. When the engagement projection is fitted into the engagement opening, the small protrusions are elastically urged against the inner peripheral surface of the engagement opening. In this way, even when the two members have different thermal expansions, no play or no excessive stress is generated between the two members.Type: GrantFiled: June 11, 1996Date of Patent: March 24, 1998Assignee: Ebara CorporationInventors: Hiroyuki Kato, Shuichiro Honda

Patent number: 5585163Abstract: A ceramic-metal composite assembly includes a ceramic member having a stab shaft and a metallic member having a recess. The ceramic member and the metallic member are joined together by press fit, i.e., by fitting the stab shaft into the recess. The stab shaft and the recess after extraction of the stab shaft from the recess has a set relationship of 50 .mu.m.ltoreq.X-Y.ltoreq.150 .mu.m where X is an outer diameter of the stab shaft and Y is an inner diameter of the recess whilst a surface roughness Rz of the recess in the circumferential direction thereof after extraction of the stab shaft from the recess is 1.5 .mu.m or less.Type: GrantFiled: December 1, 1993Date of Patent: December 17, 1996Assignee: NGK Spark Plug Co., Ltd.Inventors: Takaya Yoshikawa, Hiroki Nakajima, Masaya Ito, Noboru Ishida

Patent number: 5573344Abstract: A design for a high damping composite joint which dissipates vibrations through the use of air gaps and viscoelastic material minimizing the transfer of vibrations to the metallic coupling. Viscoelastic material is used with adhesive to provide for increased energy dissipation by the joint. As the load increases on the joint, the load transfers from adhesive to the viscoelastic. The viscoelastic begins to take the load of the joint at the point where the adhesive becomes plastic. Acoustic vibrations are then dissipated in the viscoelastic and are prevented from being transferred to the metallic coupling by air gaps provided in the joint. The amount of viscoelastic and adhesive used depends on the anticipated load. Finite element analysis is used to calculate optimal amounts of viscoelastic and adhesive.Type: GrantFiled: October 17, 1994Date of Patent: November 12, 1996Assignee: The United States of America as represented by the Secretary of the NavyInventors: Roger M. Crane, Douglas C. Loup, John W. Gillespie, Jr., Stephen M. Andersen, Daniel D. Coppens

Patent number: 5439306Abstract: Device for assembling two elements made of materials having different coefficients of thermal expansion, which are subject in use to substantial temperature variations, is provided with a combination of a layer of a compressible, heat insulating material, positioned between a support element and an attached element, and an mechanism for maintaining the attached element against the layer, and the layer against the support element. The mechanism is arranged so as to enable relative movement between the two elements in a plane substantially parallel to the plane of the layer. Also, surface portions of the attached element in contact with the mechanism are substantially parallel to the plane of the layer, and a material similar to the material of the layer is positioned between the surface portions and the mechanism. The device is especially applicable to the attachment of insulating elements on a metallic structure.Type: GrantFiled: November 30, 1994Date of Patent: August 8, 1995Assignee: Societe Nationale Industrielle et AerospatialeInventor: Jacques C.

Patent number: 5431506Abstract: This invention relates to the property of a bonded metal including a forming material of a nickel-titanium alloy and its method of manufacture. This bonded metal property is produced by forming a forged structure to achieve an incorporated integral body through the bonding of the nickel-titanium alloy material onto another material of nickel base alloy. The manufacturing method used to achieve this property involves heating both materials at the point to be bonded in an inert gas atomosphere. The materials are first heated to their melting point and in this state are fused together under high pressure. This forms the forged structure on the portion of the materials so treated.Type: GrantFiled: May 14, 1992Date of Patent: July 11, 1995Assignees: Masunaga Menlo Park Co., Ltd., Furukawa Electric Co., Ltd.Inventor: Satoru Masunaga

Patent number: 5431020Abstract: In a heat shield on a load-bearing structure, the heat shield has a multiplicity of tiles which are in contact with the load-bearing structure, are adjacent one another for substantially covering an area and are fastened by means of approximately L-shaped metallic restraints that are anchored in grooves of the load-bearing structure. The restraints may be completely screened by hot sides of the tiles facing towards a hot fluid. It is also possible to avoid the use of expensive fastening devices for the restraints. The configuration of the heat shield on the load-bearing structure is very highly thermally load-resistant, simple to manufacture and does not expose the tiles to any stresses which could be critical with respect to the brittleness of the ceramic.Type: GrantFiled: November 2, 1994Date of Patent: July 11, 1995Assignee: Siemens AktiengesellschaftInventor: Helmut Maghon
