A liquid container includes a container portion and a lid. The container portion includes a plurality of storage portions separated by at least one partition rib and storing liquid respectively in an isolated state. The lid bonded with the container portion so as to cover an opening region of the container portion. A plurality of project portions engaging with the partition rib so as to sandwich the partition rib from both sides of the partition rib is integrally molded with the lid. In a state in which the partition rib is engaged with the project portions, a bonding portion is filled with bonding resin so as to seal a cavity between an edge end of the partition rib and the lid and a cavity between an edge end of an outer circumference of the container portion and the lid.

Provided is a manufacturing device for a rotor core and a manufacturing method for a rotor core in which it is possible to suitably fit a columnar core rod into a center hole of a laminated iron core, when fitting and installing the laminated iron core into a fitting recess of a first mold. A device for manufacturing a rotor core includes: a first mold; a second mold that engages with the first mold and clamps and seals the laminated iron core together with the first mold; a resin injection unit that is provided to the second mold and injects a resin material in the magnet insertion hole by using a molding machine; and a guide plate that has a through hole into which the core rod is inserted and is mounted at one end of the laminated iron core in such a manner that the through hole is in communication with the center hole of the laminated iron core, in which the guide plate has an opening diameter of the through hole on one surface side of one end side of the laminated iron core that is substantially the same as an opening diameter of the center hole, and an opening diameter of the through hole on the other side on the side of the first mold is larger than an opening diameter on the one surface side.

A casing structure including a plastic casing, at least one metal component, and a conductive layer is provided. The at least one metal component is disposed on the plastic casing, and at least one side surface of the at least one metal component is covered by the plastic casing. The conductive layer is disposed on the metal component and extends to the plastic casing. In addition, a manufacturing method of the casing structure is also provided.

A filling device for the joint that provides filling of the desired area to be poured in cases where similar electrical transmission systems or components such as low and high voltage busbars and cables are attached to each other.

A sealing method for sealing an opening of a metallic molded body with a resin molded body, the metallic molded body having a cavity therein and an opening connected to the cavity, includes a step of irradiating laser light onto a joining surface on a periphery of the opening of the metallic molded body in an energy density of 1 MW/cm.sup.2 or more and at an irradiation rate of 2000 mm/sec or more to roughen the surface, and a step of placing, in a mold, a portion including the joining surface of the metallic molded body roughened in the preceding step and sealing the opening with a resin molded body formed by injection molding or compression molding of a resin.

Magnetic field generating unit 2 is fixed to object 7 that moves relative to magnetic field detecting means 3. Magnetic field generating unit 3 has magnetic field generator 4, first support structure 5 that is fixed to object 7 and second support structure 6 that is independent of first support structure 5. Second support structure 6 is supported by first support structure 5 and supports magnetic field generator 4. For example, second support structure 6 is formed of a nonmagnetic material, and magnetic field generator 4 is arranged away from first support structure 5.

A guide shoe for an elevator is formed entirely of plastic materials and includes a guide shoe housing, a damping element and a guide element that are firmly bonded to one another and form a one-piece composite structure. The composite structure is produced by a three-component injection molding process.

An optical fiber mold device has a first portion that includes a base layer having a longitudinal feature configured to receive an optical fiber. At least one second portion is disposed over the base layer. The second portion has a center wall and front and back end walls. The center wall, the front end wall, and the back end wall form a mold cavity. At least one first hole is disposed in the mold cavity and is configured to allow mold material to enter the mold cavity. At least one second hole in the mold cavity is configured to allow air displaced by the mold material to exit the mold cavity.

A CFRP material with an Al alloy sheet attached to or a CFRTP material with an Al alloy sheet attached to is prepared by joining an Al alloy sheet with a CFRP material or a CFRTP material by adhesion or by injection molding. The surface of this Al alloy sheet and a surface of metal material such as Ti, etc., are subjected to chemical treatment. After this chemical treatment, the CFRP material with an Al alloy sheet attached to or the CFRTP material with an Al alloy sheet attached to and the metal material are inserted into a metallic mold for injection molding so as to have a gap therebetween. High crystalline thermoplastic resin is injected into this gap to join the metal material with the Al alloy sheet, thus obtaining a laminated composite.

The invention relates to a thermoplastic elastomeric bellow duct (10) having a corrugated duct segment (12) interposed between two elbowed segments (14, 18), wherein at least one of the elbowed segments (18) is made of thermoplastic elastomeric and connected to an end section (22) of the corrugated duct segment (12) by overmolding the elbowed segment (18) over the end section (22) of the corrugated duct segment (12), and wherein the end section (22) of the corrugated duct segment (12) includes a guiding and sealing arrangement (50) pointing away from the corrugated duct segment (12) in a radial direction (32). The invention further relates to an air duct (80) having such a thermoplastic elastomeric bellow duct (10).
