A method of making a worm gear. The method includes forming a gear blank having a plurality of individual lugs formed about an outer circumferential edge of said blank to facilitate a uniform flow of a material around said plurality of individual lugs. The method also includes molding said material around said plurality of individual lugs to form a ring.

A wire embedding system and methods are presented. A wire is embedded in a substrate at predetermined locations in a series of sequential embedding instances using heat and pressure. The heat and pressure are removed from the wire in between the series of sequential embedding instances.

A water-using household appliance, in particular a household dishwashing machine, includes a wall which is made from a metal material, and a device which is made from a plastic material and fixedly connected to the wall by a laser weld.

A manufacturing apparatus of a metal-composite patch part and a manufacturing method thereof include: a laser oscillator oscillating a laser; a first laser irradiator used to perform pattern processing on one surface of a metal with a laser by receiving the laser from the laser oscillator; and a metal-composite bonding apparatus for bonding a composite tape to the one surface of the pattern-processed metal. The apparatus includes a feeder roller supplying a composite tape to the one surface of the pattern processed metal and a pressing roller pressing the composite tape to the one surface of the metal. The bonding performance between the metal and the composite and productivity may be improved because the number of the processes related to the metal-composite patch part manufacturing process may be significantly reduced.

A method for manufacturing a metal-resin joint 30 according to the present disclosure is a method for manufacturing the metal-resin joint 30 in which a synthetic resin member 10 made of thermoplastic resin and a metal member 20 made of metal are bonded to each other, the method including: a first process of exposing a surface 12 of the synthetic resin member 10 molded into a predetermined shape, to air heated to a first temperature T1 equal to or higher than a deflection temperature under load Tf of the thermoplastic resin when a load of 1.8 MPa is applied; and a second process of bonding the surface 12 of the synthetic resin member 10 and a surface 22 of the metal member 20 to each other. Accordingly, it is possible to improve the bonding strength between the metal member 20 and the synthetic resin member 10.

A processing method for a wafer includes a thermocompression-bonding sheet arrangement step of arranging, on a front side of the wafer, a thermocompression-bonding sheet of a size sufficient to cover the wafer, an integration step of pressing the thermocompression-bonding sheet under heat by a planarizing member, so that the thermocompression-bonding sheet is planarized and the thermocompression-bonding sheet and the wafer are integrated together, a grinding step of holding the wafer on a side of the thermocompression-bonding sheet on a chuck table of a grinding apparatus and grinding the wafer to a desired thickness while supplying grinding water to a back side of the wafer, and a thermocompression-bonding sheet rinsing step of unloading the integrated wafer from the chuck table and rinsing the thermocompression-bonding sheet.

A laminated body in which a thermoplastic resin layer, a thermosetting resin layer, and a protective film are layered one on another in this order, in which the thermosetting resin layer contains a thermosetting resin composition containing two or more kinds of organometallic complex, a surface of the protective film at an opposite side of the thermosetting resin layer has a surface roughness Ra of 30 nm or less, and an amount of nitrogen atoms present at the surface of the protective film at the side of the thermosetting resin layer is less than 1 atm %.

An explosion-proof housing includes at least one metal housing part having at least one of a housing opening or receiving surface, and a support edge bordering said at least one of a housing opening or receiving surface. A cover part covers said at least one of a housing opening or the receiving surface. The cover part includes a peripheral cover edge which is connected to the support edge in an explosion-proof manner such that in the event of an explosion inside the housing, the explosion is prevented from crossing over to an explosive atmosphere surrounding the housing. A plurality of connection points are formed between the support edge and the cover edge. The connection points include interlocking depressions and protrusions. The protrusions are formed by partial melting of the cover edge. The depressions and the protrusions interlock with play in a longitudinal direction of the housing.
