Abstract: In a method for manufacturing a composite-metal-forming material, heating a metal material a Mg alloy or an Al alloy is heated to a temperature in a region where a solid and a liquid are both present to thereby yield a semi-molten metal material in a semi-molten state. An additive material is introduced to the semi-molten metal material and kneading is performed to obtain a composite metal material. The composite metal material is heated to a solution temperature of the metal material and a solution treatment is performed to thereby yield a composite-metal-forming material.

Abstract: A device for melting, storing, and feeding a metal material is provided which can store a large amount of molten metal material corresponding to molding cycles with a compact configuration, using barrels to melt bar-shaped metal materials and a tank-and-barrel storage unit to store the molten metal material. The storage unit for the molten metal material is composed of an upper storage tank and a lower material temperature control barrel having a smaller diameter, the barrel being perpendicularly arranged under and in communication with the bottom center of the tank. The melting barrels for bar-shaped metal materials are made of barrel bodies having an inside diameter and a length appropriate to accommodate the bar-shaped metal materials. A more than one melting barrel is vertically arranged in parallel on a lid member of the storage tank, with their bottom openings facing the inside of the storage tank.

Abstract: An electrical connector is offered which has a crimp contact connected with a connector cable, the crimp contact being held in position to a connector housing without rattling. The crimp contact has sidewall surfaces of U-shaped cross section. The sidewall surfaces are located on opposite sides. The sidewall surfaces have outwardly facing engagement protrusions. The connector housing has a connector body and a disengagement-preventing cover for closing a top portion of the connector body to prevent the crimp contact from coming off upward after the crimp contact has been mounted in the connector body. The connector body has engagement portions in which the protrusions of the crimp contact are inserted and received perpendicularly to the longitudinal direction of the connector cable. The protrusions are engaged in the engagement portions. The disengagement-preventing cover is mounted to the connector body via a hinge such that the cover can be opened and closed.

Abstract: A method for kneading a carbon nanomaterial with a metal material and manufacturing a composite-metal-forming material. A semi-molten metal material obtained by heating the metal material to a temperature of a region where a solid and a liquid are both present is kneaded with the carbon nanomaterial, and the composite metal material is obtained. The composite metal material is heated to the solution temperature of the metal material, and a solution treatment is performed, whereby the composite-metal-forming material is obtained.

Abstract: To prevent damage by an external force in a retainer attached mold case of a plug connector including an insulating member having aligned containing holes containing contacts, a shield case surrounding the insulating member, a substantially cylindrical mold case incorporating these therein and having slits for grounding at two side walls thereof and an elastic claw with a lock portion and a lock release portion at an upper face, and a retainer for closing a rear end opening of the mold case excluding a cable inserting portion, a locking projection is projected to a rear side from a rear end portion of the elastic claw, and a float preventing piece for preventing the elastic claw from floating up by engaging with the locking projection is projected from a front end portion of the retainer.

Abstract: A method of preventing leaking of molten metal from a nozzle in an injection apparatus comprising, metering the molten metal by travel of a plunger head backward from a most forward position to a most backward position at the rear of a supply opening while maintaining nozzle contact after completion of an injection step and supplying molten metal from a furnace into a cylinder body through the supply opening, after completion of the metering, closing the supply opening by travel of the plunger head forward at a low speed from the backward position to a stand-by position ahead of the supply opening for cutting off the communication between the molten metal in the cylinder body and the molten metal in the furnace.

Abstract: An electrical connector having a contact connection portion electrically shielded better than heretofore. The connector is reduced in size and cost. The connector has contacts connected with a signal line, an insulative housing, and a metal shell surrounding and electrically shielding the housing except for a connection portion that is a region necessary for connection with a mating member. The housing has accommodation portions for receiving the contacts. A part of the metal shell has a shielding wall surface surrounding the entire outer periphery of a peripheral wall forming the connection portion of the housing with a given gap therebetween. The four sides of the shielding wall surface have lock portions by which the receptacle connector of the mating member is engaged and anchored.

Abstract: An electrical connector capable of being assembled at improved efficiency. The connector includes an insulative housing having contact accommodation portions, which are closed by a cover member having lock means. Contacts with which a cable is connected are received in the contact accommodation portions of the housing. The housing is fabricated integrally with the cover member via a hinge. The cover member closes openings in the accommodation portions. The lock means has engagement pawls standing upright from the upper surface of the housing. When the accommodation portions are dosed, the engagement pawls come into engagement with engagement portions formed in the cover member.

Abstract: This is provided a method for preventing leaking of molten metal from a nozzle in an injection apparatus provided with a plunger within a cylinder body, a supply opening formed in an upper portion of the cylinder body, and a furnace for melting and holding the metal material provided on a top portion of the injection cylinder and having an outlet at the bottom end of the furnace communicated with the supply opening.

Abstract: To prevent from being destructed by an external force in a retainer attached mold case of a plug connector including an insulating member having aligned containing holes containing contacts, a shield case surrounding around the insulating member, a substantially cylindrical mold case incorporating these therein and having slits for grounding at two side walls thereof and an elastic daw with a lock portion and a lock release portion at an upper face, and a retainer for dosing a rear end opening of the mold case excluding a cable inserting portion, a locking projection is projected to a rear side from a rear end portion of the elastic daw, and a float preventing piece for preventing the elastic daw from being floated up by engaging with the locking projection is projected from a front end portion of the retainer.

Abstract: To improve connector installation density and utilize space effectively, a cable-equipped connector is capable of coupling separation-prevention lock screws at any position around the other connector. The cable-equipped connector includes a connector body, a cable connected to a rear of the connector body, an insulating synthetic resin housing that covers a connecting portion, a mounting block disposed so as to be rotatable with respect to the housing, and lock screws that rotatably engage through-holes formed in both ends of the mounting block.
