Methods of manufacturing vehicle assemblies, such as engine assemblies, are provided. The method includes arranging at least a first component in a mold, arranging a second component or a second component precursor adjacent to the first component in the mold, introducing a sacrificial material into the mold, introducing at least one polymeric fluid into the mold, solidifying the polymeric fluid, and removing the sacrificial material from the mold to form a void space so that the first component, the polymeric composite material, and the void space define the vehicle assembly.

A gear box includes a gear box body, and a terminal which is integrated with the gear box body. The gear box body includes a storage portion which stores a gear, a motor insertion portion, recessed in an attachment surface of a motor, and a connector connection portion on the same side as the motor insertion portion with respect to a rotation center of the gear and is open in a direction different from the motor insertion portion. The terminal includes the connector terminal which is exposed to the inside of the connector connection portion, a motor feeding portion which is exposed to the inside of the motor insertion portion, a connecting portion which is in the gear box body and connects the connector terminal and the motor feeding portion, and a fixing tab extending from the connecting portion and exposed to the inside of the motor insertion portion.

A motor assembly tool includes a stator defining a plurality of slots and a varnish application fixture. The fixture includes a disc defining a plurality of slots, an outer shield disposed on the disc radially outward of the slots of the disc, and an inner shield disposed on the disc radially inward of the slots on the disc. The disc is disposed on the stator and the outer and inner shields are configured to direct varnish through the slots of the disc and into the slots of the stator.

A generator injection tool is provided. The generator injection tool injects an adhesive into a generator that includes a rotor positioned within a stator having a stator vent, the stator and rotor having a gap therebetween. The generator injection tool includes a first carriage sized to fit within the gap, a tube, a first motor, a controller, and an adhesive source. An end of the tube is movable between a first position in which the end is outside of the stator vent and a second position within the stator vent. The first motor is operable to move the tube between the first position and the second position. The controller is operable to selectively activate the first motor to position the end of the tube within the stator vent. The adhesive source moves the adhesive through the tube end to inject a portion of the adhesive into the stator vent.

The present invention provides a coupler comprising: an inner insertion part including a through-hole; and an outer support part for encompassing the outside of the inner insertion part, wherein the inner insertion part includes a connection groove through which the outer support part passes, the outer support part includes at least one projection part protruding in the center direction of the through-hole, and the projection part includes a groove part.

A rotor core manufacturing equipment used in a manufacture of a rotor core where magnets are inserted into magnet housing holes formed in a core body and a resin is supplied into the holes and subsequently cured therein. The equipment includes a stationary mold for holding the core body, a movable mold which is arranged on the core body and in which a resin flow passage is formed, and a cull plate that is arranged between the core body and the movable mold, the cull plate including a filling pot that guides the resin flowing out through the resin flow passage to the magnet housing holes and holds a cull as the cured resin. The filling pot includes an inlet which is opposite an outlet of the resin flow passage. The inlet of the filling pot has an area greater than the outlet of the resin flow passage.

The present invention provides a method for producing molded articles by joining primary molded parts by injection welding, by which a molded article composed of primary molded parts that are joined with high weld strength can be produced. The present invention relates to a method for producing molded articles including a welding step of injecting an injection welding material containing a polyamide around or between butt weld portions of primary molded parts disposed in face-to-face contact, so as to weld the primary molded parts together to form a molded article. The polyamide contains dicarboxylic acid units and diamine units. This polyamide further contains triamine units in an amount of 0.05 to 1 mol % with respect to the total dicarboxylic acid units.

A bending actuator and methods for making and using the same. A beam of anisotropic polymer material, such as nylon, characterized by a greater degree of molecular orientation along a longitudinal axis than transverse to the longitudinal axis, has a heating element in thermal contact with at least one of a pair of opposing faces parallel to the longitudinal axis of the beam. The heating element in certain embodiments provides for photothermal activation of the bending actuator.

A thermal insulation structure for an electronic device of the present invention is a thermal insulation structure which thermally insulates between an electronic circuit unit and a heat generator formed with another component. In the thermal insulation structure, a partition wall for separating each space and formed of resin having electric insulation properties is provided between the electronic circuit unit and the heat generator. Also, the partition wall is formed by integrating the resin and a thermal insulation material having thermal conductivity lower than thermal conductivity of air so that the resin includes the thermal insulation material. Further, the partition wall is formed by insert-molding the thermal insulation material with the resin. Further, the resin having the electric insulation properties is thermoplastic resin, and a thermal insulation raw material of the thermal insulation material is silica xerogel.

An electronically commutated direct current motor with a housing, a housing cover, a bearing shield, a rotor and a stator, wherein the rotor includes a shaft and a permanent magnet and the stator consists of single terminals, which are provided with terminal insulation. The direct current motor ensures a space-saving construction connection of motor components or components with the housing of the electronic commutated direct current motor, conforming to its class, wherein additional connections or sealing elements are not required, wherein a firm and sealed connection can be manufactured upon demand and an easy integration of other functions and interfaces is possible.
