One aspect is a method of manufacturing a lead connector for an implantable medical device. The method includes connecting proximal ends of a plurality of conductive pins to a corresponding one of a plurality of ring contacts to form a plurality of ring-pin subassemblies, assembling each of the plurality of ring-pin subassemblies on an assembly frame, including inserting the plurality of conductive pins in a corresponding plurality of openings within the assembly frame such that the corresponding plurality of ring contacts are spaced along a longitudinal dimension of the assembly frame, arranging the assembly frame along with the conductive pins and corresponding ring contacts within a mold cavity, filling the mold cavity with a mold material that surrounds the assembly frame, and removing a resulting lead connector from the mold cavity.

A holding portion having a diameter larger than that of a cavity is formed in communication with the cavity, in an area of a two-part type mold, the area including a portion corresponding to an annular groove. Subsequently, an insert member formed in a cylindrical shape and provided with, on an outer circumferential surface, the annular groove having no step in a groove surface is fitted to the holding portion, and then the mold is closed. On an inner circumferential surface of the insert member, a surface treatment layer having a surface roughness rougher than those of other portions of the insert member is formed. Molten resin is injected into the cavity; thereafter, an assist material is injected into the cavity to mold the resin into a desired pipe body. Then, the insert member and the pipe body are integrated along with curing of the resin.

A sintered component forming step is for forming a sintered component by powder molding. An insert forming step is for forming a sintered insert component in which an exterior component is integrated on an outer peripheral portion of the sintered component. One or more grooves or ridges are formed on an outer peripheral portion of a region except for one end portion of the sintered component in the sintered component forming step. The insert forming step includes a step for bringing the outer peripheral portion of the end portion into contact with an inner peripheral surface of an insert forming mold along a circumferential direction and covering the one or more grooves or ridges by the insert forming mold with an interval to form a cavity on an outer peripheral portion of the sintered component and a step for filling a melted material in the cavity.

A vehicle-window glass assembly includes a vehicle-window glass and its injection-molded encapsulation; and an over-molded bolt including a base, a thread rod and an injection-molded part. One end of the thread rod is fixedly connected to the base, and the injection-molded part covers at least a part of the base. The injection-molded encapsulation covers at least a part of the injection-molded part such that the over-molded bolt and the vehicle-window glass are fixed to each other, and a material of the injection-molded part has a tensile strength greater than that of a material of the injection-molded encapsulation. This vehicle-window glass assembly can b e adapted to various vehicle models with a large gap between a surface of a vehicle-window glass and a vehicle-door sheet metal on which the vehicle-window glass requires to be mounted.

A gaming chip in which it is not easy to remove an RFID tag and difficult to damage the RFID tag through use is provided. A gaming chip that incorporates a sticker-type RFID tag including an enclosing member having a predetermined shape for enclosing the RFID tag; a body member that is injection-molded to encapsulate the enclosing member with the RFID tag; and a gaming chip for amusement. The enclosing member consists of a first part and a second part, and at least the first part or the second part has a flat surface to which a sticker-type RFID tag can adhere, and the first part and the second part are combined to form an enclosing member, in which the sticker-type RFID tag is covered by the first part and the second part.

A spray tip comprises a tip body, a tip piece, and a pre-orifice piece. The tip body has a fluid channel along a channel axis (A.sub.C). The tip piece is disposed within the fluid channel, and has a stepped, narrowing passage that terminates in an outlet orifice. The pre-orifice piece has an inlet passage, and is disposed within the fluid channel, abutting and immediately upstream of the tip piece. The pre-orifice piece and the tip piece together define a turbulating chamber therebetween.

A method for manufacturing three-dimensional items with flexible walls is provided, by method of a mold and counter-mold between which a volume corresponding to that of the item to be obtained is delimited. The item is made up of laminar parts which are mounted on a template that is fixed to the inner surface of the mold. The laminar parts are joined to one another by means of a material which is injected in molten state through a network of conduits delimited between the counter-mold, template and the facing edges of adjacent laminar parts. The template is made of an elastically deformable material and has a three-dimensional configuration.

The present invention provides a method for manufacturing a metal-resin composite including a metal plate and a thermoplastic resin that directly covers at least a part of one surface of the metal plate.

As the method includes a support member placing step of fixing a resin support member for supporting the metal plate, in a mold, a metal plate placing step of placing the metal plate on the support member, and an integrating step of integrating the thermoplastic resin that is applied to a support member side of the metal plate, the support member, and the metal plate, into one body in the mold, the metal-resin composite that is unlikely to have a peeling start point of the thermoplastic resin is manufactured.

An injection molding method for a semifinished product includes a semifinished product emplacement step, a semifinished product pre-compression step and a forming step. First, a pair of mold with a forming space is provided. A semifinished product is put into the mold, and a first joint is performed to the mold by a press-fit jig, fixing the semifinished product in the forming space. The semifinished product is also tightly fitted with the mold. Next, a first open-die is performed and the press-fit jig is removed. After that, a second joint is performed, and a forming material is injected into the forming space. Finally, a second open-die is performed, and then a finished product is formed. By the semifinished product pre-compression step, the forming material can be prevented from resulting in spill or burr on the semifinished product, thereby improving the yield of injection molding.

A spray tip comprises a tip body, a tip piece, and a pre-orifice piece. The tip body has a fluid channel along a channel axis (A.sub.C). The tip piece is disposed within the fluid channel, and has a stepped, narrowing passage that terminates in an outlet orifice. The pre-orifice piece has an inlet passage, and is disposed within the fluid channel, abutting and immediately upstream of the tip piece. The pre-orifice piece and the tip piece together define a turbulating chamber therebetween.
