The aluminum bonding member 10 has an aluminum member 12 of aluminum or an aluminum alloy exposed to the outside, and a tubular member 14 of a material which does not melt at a temperature close to the melting point of aluminum or the aluminum alloy. Both of the opening end portions of the tubular member 14 are open to the outside of the aluminum member 12. A portion of the tubular member 14 between the opening end portions extends in the aluminum member 12, and the outer peripheral surface of the portion of the tubular member 14 extending in the aluminum member 12 is bonded directly to the aluminum member 12.Type: GrantFiled: February 24, 2012Date of Patent: June 10, 2014Assignee: Dowa Metaltech Co., Ltd.Inventor: Hideyo Osanai

Publication number: 20140150596Abstract: Construction is achieved that is capable of maintaining overall strength of a cylindrical-shaped steering column, while at the same time making it possible to make the thickness part of the steering column thin. An outer column 10b, which is a column member of a steering column is formed by connecting in the axial direction a main portion 18 made using a light metal alloy with a cylindrical member 19 made of an iron-based alloy by a concave groove 20 that is formed around the outer circumferential surface of the front end section of the cylindrical member 19 engaging with a protrusion 21 that is formed around the inner circumferential surface of the rear end section of the main portion 18. A ring 22 made using a metallic material is fitted and fastened inside the inner diameter side of the cylindrical member 19 in the connecting section between the main portion 18 and the cylindrical member 19.Type: ApplicationFiled: July 23, 2012Publication date: June 5, 2014Applicant: NSK, LTD.Inventor: Makoto Nagasawa

Publication number: 20140150985Abstract: A method of forming a casting includes providing a preform to a mold cavity. The preform is formed from one of a first metal and a second metal and defines an interface surface. A molten portion of the other of the first metal and the second metal is cast into the mold such that the molten portion proximately contacts the interface surface of the preform. An interface layer at the interface surface, a first portion defined by the mold cavity and the interface layer, and a second portion defined by the interface layer, are formed during casting. The interface layer may define a metallurgical bond between the first portion and the second portion. In the non-limiting example provided herein, the first portion is substantially comprised of aluminum and the second portion is substantially comprised of magnesium. In a non-limiting example, the casting may be configured as a vehicle wheel.Type: ApplicationFiled: February 4, 2014Publication date: June 5, 2014Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Blair E.

Patent number: 8714953Abstract: A vulcanizing mold manufacturing method, and a tire vulcanizing mold are disclosed. Tubular bodies each formed by oppositely arranging the inner peripheral surfaces of both end portions of a plate-shaped body are each arranged so that the gap between both opposite end portions thereof is narrowed and that the tips of both end portions come in contact with the surface of the plaster mold, by inserting and fitting both opposite end portions into a fitting portion of a plate-shaped metal fitting protruding from the surface of the plaster mold. Molten metal is poured over the surface of the plaster mold to embed the tubular body in a mold while exposing the tips of both opposite end portions at the tire molding surface of the mold. The metal fitting is removed from the mold, so that a mold having a small gap between both opposite end portions is manufactured.Type: GrantFiled: April 10, 2012Date of Patent: May 6, 2014Assignee: The Yokohama Rubber Co., Ltd.Inventor: Noboru Takada

Publication number: 20140090795Abstract: An LED heat sink and a manufacturing method thereof are disclosed. The LED heat sink includes a main body having a heat receiving section and an extended heat transfer section. The heat transfer section is externally provided with a plurality of receiving grooves for correspondingly connecting with a plurality of radiating fins. The LED heat sink manufacturing method includes the steps of molding a main body using a half-molten metal material and cooling the main body, so that the cooled main body is connected with a plurality of radiating fins to form an integral unit. With the LED heat sink manufacturing method, it is able to manufacture an LED heat sink having a relatively complicated radiating fin structure or being formed of two or more types of materials, and to largely reduce the time, labor and material costs of the LED heat sink.Type: ApplicationFiled: November 26, 2013Publication date: April 3, 2014Applicant: Asia Vital Components Co., Ltd.Inventors: Sheng-Huang Lin, Kuo-Sheng Lin

Patent number: 8672018Abstract: A cylinder head is formed by positioning a clad preform including a first and second layer in a casting die cavity with the second layer in communication with the die cavity and the first layer facing outwardly to define a combustion surface. Molten material provided to the die cavity is solidified to form a cast portion metallurgically bonded to the second layer. An aperture of the preform forms a port in fluid communication with a passage of the cast portion. A plurality of dome-shaped preforms may define the combustion chambers of a cylinder head formed by the method. The preform may define a cylinder head face. The first layer may be a steel-based layer, and the second layer and cast portion may be aluminum-based, such that the first layer and combustion surface has higher thermal fatigue strength relative to the cast portion.Type: GrantFiled: August 20, 2012Date of Patent: March 18, 2014Assignee: GM Global Technology Operations LLCInventors: Devin R. Hess, Gerald F. Johnson
