摘要:
A process for bonding a polyolefin, polyfluoroolefin, polyethylene terephthalate, polyacetal, nylon or plasticizer-rich soft polyvinyl chloride substrate to a like substrate or for bonding a polyolefin, polyfluoroolefin, polyethylene terephthalate, polyacetal, nylon or plasticizer-rich soft polyvinyl chloride substrates to another substrate which comprises applying to the surface of at least one of the substrates to be bonded together an adhesion promoter composition comprising 0.001-10 wt. % of at least one organometallic compound containing a metal selected from the group consisting of typical metals, applying a cyanoacrylate-based adhesive comprising an alpha-cyanoacrylate and bringing together the thus-treated surface of the substrates to be bonded.
摘要:
A method of manufacturing molding members, for instance for automobiles, wherein an elongate shaped body is prepared from synthetic resin material either by an extrusion process, or by an injection process and is subjected to a controlled heating so as to soften the interior resin material while preserving the hardness of the outer surface portion. A cutter blade is advanced into the shaped body while it is subjected to the controlled heating, whereby the outer surface portion is urged and deformed inwardly to form a smooth end surface in continuous connection with remaining outer surface of the molding member.
摘要:
A primer comprising at least one member selected from organometallic compounds, natural resins and synthetic resins and at least one fluorine-containing compound of a specific type, which is particularly useful in bonding non-polar or highly crystalline substrates together or bonding another material to the resin substrate.

The present invention provides a wrist mechanism with three degrees of freedom for an industrial robot, which is compactly formed and to which a tool is mounted. The first degree of freedom is associated with a first input shaft for rotating a wrist portion at a low speed. The second and third degrees of freedom are associated with rotating the tool or tilting the wrist. In order to attain these motions, second and third input shafts concentrically arranged relative to the first input shaft are used for transmitting motion to, through bevel gears, speed reduction mechanisms each symmetrically disposed at right and left sides, and the outputs therefrom are used to drive the tool and wrist.
摘要:
An adhesive composition comprising an .alpha.-cyanoacrylate and about 0.0001% by weight to about 20% by weight, based on the weight of the adhesive composition, of at least one compound selected from the group consisting of(1) polyethylene glycols having a degree of polymerization of at least 3, and(2) non-ionic surface active agents having a poly(ethyleneoxy) moiety therein with the poly(ethyleneoxy) moiety having a degree of polymerization of at least 3.
