An electric valve can be further miniaturized while reducing the number of manufacturing man-hours. The electric valve contains: a motor including a stator member and a rotor member that displace a valve body, and a housing for accommodating the motor. The housing is formed by joining a heat generation portion formed of a first material to a heat receiving portion formed of a second material. The light transmittance in the first material is lower than the light transmittance in the second material.

The invention relates to an apparatus and to a method for establishing a connection having material continuity or having material continuity and shaping matching or for separating such a connection of at least one metal or ceramic component and of a component formed from or by a thermoplastic polymer in which the components to be joined together can be pressed together by a pressing device having a counterholder and a plunger. A heating device is present at the plunger and/or at the counterholder or acts there. A heating of the at least one metal or ceramic component up to above the softening temperature of the component formed from or by polymer can be achieved with the heating device, with the heating device being having at least one electrical resistance heating element that is covered by an electrically insulating, preferably ceramic, protective film, and/or having at least one laser beam that is directed to the metal component(s) within the joining region, and/or having at least one inductor present at the plunger and/or at the counterholder for the inductive heating of the meal component(s).

A method for producing a receptacle which is closed by a sheet by transmission laser welding, and to an apparatus suitable to carry out same. The method and the apparatus are configured in such a way that a weld seam is formed between the wall structure of the receptacle and the sheet so as to be wider than the end faces of the wall structure.

The invention relates to an edge trim for pieces of furniture, comprising a meltable layer. In order to improve a generic edge trim such that the same is more versatile and can especially be mounted on a wider selection of surfaces, the molecular structure of the meltable layer contains both polar and non-polar parts.

A pull-on garment (1) includes an outer cover (3) forming an outer surface of the garment, both lateral side edge portions of the outer cover in a front body portion F and both lateral side edge portions of the outer cover in a back body portion R being joined to each other to form a pair of side seals (4), a waist opening (8), and a pair of leg openings (9). Each of the side seals (4) includes a seal edge portion (41) where the edge portion (3F) of the outer cover (3) in the front body portion F and the edge portion of the outer cover (3) in the back body portion R are bonded to each other by a continuous linear fusion-bonded portion (40) extending in a longitudinal direction of the side seal (4). In a cross-section orthogonal to a direction in which the side seal (4) extends, the fusion-bonded portion (40) includes a narrow section (4F) which is formed at a middle portion thereof in the thickness direction Q and of which a width W along the inner-to-outer direction P is small. The narrow section (4F) includes broad sections (4A, 4B) which are provided on both sides of the narrow section (4F) in the thickness direction Q and of which the width W is larger than the width of the narrow section (4F).

A fueling device includes a fuel passage-forming member and a flap valve mechanism. The flap valve mechanism includes an opening-forming member attached to one end of the fuel passage-forming member and an opening-closing mechanism to open and close a filler inlet of the opening-forming member. The fuel passage-forming member includes a pipe body containing a resin inner layer in a pipe shape made of a first resin material and a resin outer made of a second resin material, and a welding end formed on an opening end of the pipe body. The opening-forming member includes a cover member that covers the opening end of the pipe body and a welded end formed on an opening end of the cover member and welded to the welding end. The cover member is made of a third resin material welded to either one of the first resin material and the second resin material.

A cartridge and unit removably attachable to an image forming apparatus, allowing a member for securing a sheet member to be easily mounted with high precision, and capable of preventing leakage of a developing agent and a method for manufacturing the same are provided.A cleaning unit 2a includes a frame 24 including a waste-toner chamber 30 storing a developing agent eliminated from the image bearing member 21, an end-portion seal member 26a disposed on the frame 24 and being in contact with the image bearing member 21, a scooping sheet 15 including an end arranged on the end-portion seal member 26a and used for preventing the developing agent in the waste-toner chamber 30 from leaking through an area between the frame 24 and the image bearing member 21, and a resin member 10 for securing the scooping sheet 15 to the frame and being injection-molded to the frame 24. The resin forming the resin member 10 is made to enter the end-portion seal member 26a, and the end-portion seal member 26a and the resin member 10 are integrated.
摘要:
An apparatus for connecting two workpiece parts to form a workpiece by through-transmission welding by means of weld seams running in a preselected weld seam pattern in regions of the workpiece parts having different characteristics is provided. The apparatus has a laser beam source with a plurality of individually controllable laser beam emitters of different power which are arranged adjacently in an X direction and a homogenizer arranged downstream. At least two reflection channels are provided in the homogenizer which run parallel to one another in a Y direction and completely penetrate the homogenizer in a Z direction by a channel depth.

A device has a first part including polyethylene terephthelate (PET) with a fiber fill and a second part bonded to the first part. The second part includes an alloy of polyester and polycarbonate. The first and second part may be bonded together by placing the first part and the second part in contact with one another and heating the second part to bond the second part to the first part.

The specification and drawings present a new apparatus and method for joining a window assembly (e.g., a glass window assembly) in electronic devices using optical/laser welding. A window assembly, transparent to an optical beam, may comprise an optical window such as glass window with a laminated layer (e.g., made of plastic) glued to a backside of the optical window and a back print ink layer between portions of the optical window and of the laminated layer. This window assembly may be attached to a frame such as a plastic frame, non-transparent to the optical beam, having at least one boundary with the laminated plastic layer of the window assembly using a welding joint at the at least one boundary made by the optical beam propagating transparently (with negligible optical absorption) through the window assembly and absorbed by the plastic frame.
