Publication number: 20080131544Abstract: A mold for fabricating a device for repairing torn tissue or muscle such as the meniscus of the knee is provided. The mold includes a mold cavity adapted to receive molten material. The mold cavity has an inlet channel, a first portion, a second portion, and a first channel extending between the first and second portions. The inlet channel communicates with the first and second portions and is spaced from the first channel such that the molten material must flow from the inlet channel through the first portion or second portion before communicating with the first channel. The first channel is dimensioned to receive a first component such that the flow of molten material from the first and/or second portions into the first channel is substantially prevented when the first component is received in the first channel.Type: ApplicationFiled: October 31, 2007Publication date: June 5, 2008Inventors: Thomas W.

Patent number: 7347964Abstract: An apparatus and method for demolding golf balls from a mold cavity are disclosed. More specifically, an apparatus and method for demolding a golf ball from a mold cavity subsequent to forming a cover layer without the use of ejector or knockout pins are disclosed. The molding apparatus utilizes an undercut configuration that, upon opening the molds after molding a golf ball, serves to impart a rotational force upon the ball and dislodge it from the molds.Type: GrantFiled: August 17, 2005Date of Patent: March 25, 2008Assignee: Callaway Golf CompanyInventors: Thomas F.

Patent number: 7347963Abstract: At least a winding of a stator stack 2 is molded by injecting a fused resin molding material into a space formed between a top mold and a bottom mold member. When the stator stack 2 of the resolver, which is annular and includes a coiled winding 7, is sandwiched between the top mold member 10 and bottom mold member 20, a movable disc 12 is urged by a spring device 13, into close engagement with the bottom mold member 20. While the movable disc 12 is closely engaged with the bottom mold member 20, the stack 2 of the resolver is sandwiched between the bottom mold member 20 and the top mold member 10. This method prevents the generation of gaps between the stator stack 2 and mold 10, 20 due to unevenness of the thickness in the stator stack 2.Type: GrantFiled: April 16, 2004Date of Patent: March 25, 2008Assignee: Minebea Co., Ltd.Inventors: Shinichi Namiki, Kazunori Sakamoto

Patent number: 7326041Abstract: The preferred embodiments provide a lead frame wherein a first air vent 29 and a second air vent 30 are formed in an air vent forming region 32. When resin-molding, one end of this first air vent 29 is disposed within the cavity, whereby air in the cavity when resin-molding can be completely released to the outside of the cavity. As a result, a package after resin-molding includes no unfilled regions or voids, whereby a semiconductor device with excellent product quality can be provided. In the background, air in cavities could not be completely released when resin-molding since, for instance, one air vent was provided at a position apart from the cavity region, and unfilled regions or voids were created.Type: GrantFiled: February 6, 2004Date of Patent: February 5, 2008Assignee: Sanyo Electric Co., Ltd.Inventors: Isao Ochiai, Kazumi Onda

Publication number: 20080020081Abstract: A replaceable cavity insert for use in a multi-cavity compression mold, wherein each cavity insert is friction fitted into a respective mold recess. Each insert has a substantially semi-spherical insert surface and defined in the surface is an inverted dimple pattern of a golf ball. Each cavity insert has an O-ring recessed in the upper perimeter to limit the flow of heating and cooling fluids beyond the perimeter. The cavity insert and the O-ring are retained in the recess of the frame by a pair of removable cavity retainer screws and washers, which are countersunk into the frame and have an edge of the washer disposed in a cut-out section of the insert. Each cavity insert may be separately and individually removed from the frame by just loosening the retaining screws without the need to remove the entire frame from the press or disconnecting the utility lines leading to the frame.Type: ApplicationFiled: July 21, 2006Publication date: January 24, 2008Inventors: Robert A.
