摘要:
There is provided a spot-weldable bonded clad metal plate wherein the metal sheets are 0.05-1.0 mm thick and at least 0.4 mm thick, respectively, the adhesive layer has a thickness of 15-60 microns and the adhesive layer contains 10-100 g/m.sup.2 of metallic powder having a particle diameter corresponding to 0.5-1.5 times the thickness of the adhesive layer. The metallic powder is not necessarily entirely metallic and, for example, glass beads having surfaces coated with a metal can also be used. As the adhesive, a polyamide resin adhesive, particularly, a hot melt type polyamide resin adhesive is preferred.The bonded clad metal plate shows excellent adhesion strength, and in spite of such thin metal sheets, does not blister when spot-welded.

摘要:
A hot stamp transfer press plate comprising a transfer medium on which a transfer layer has been applied in a desired pattern, said transfer layer consisting of hot stamp ink wherein there is employed, as the binder resin of the ink, methoxymethylated nylon copolymer obtained by N-methoxymethylation of an alcohol-soluble nylon copolymer containing a higher nylon salt, .omega.-amino acid or lactam, each of which has 10 or more carbon atoms.
摘要:
A plasma processing apparatus includes a processing container, an exhaust unit, an exhaust plate, an RF power application unit connected to a second electrode but not connected to the first electrode and configured to apply an RF power with a single frequency, the second electrode being connected to no power supply that applies an RF power other than the RF power with the single frequency, a DC power supply connected to the first electrode but not connected to the second electrode, the first electrode being connected to no power supply that applies an RF power, and a conductive member within the process container grounded to release through plasma a current caused by the DC voltage, the conductive member supported by the first shield part and laterally protruding therefrom only at a position that is located, in a height-wise direction, between a mount face and the exhaust plate and below a bottom of a focus ring.
