Abstract: The present invention is a polyester film obtained by blending 10-90 wt % of polyester (A) containing ethylene terephthalate as a main constituent component and 90-10 wt % of crystalline polyester (B) different from this polyester (A), which has a half value width of a recrystallization peak obtained by a differential scanning calorimeter (DSC) by lowering temperature of not more than 0.25. The crystalline polyester (B) is preferably a polyester selected from polybutylene terephthalate (PBT), polytrimethylene terephthalate (PTT) and polyethylene 2,6 naphthalate (PEN).

Abstract: A barrier metal film, Al alloy film and anti-reflective film are sequentially deposited on a surface to form an interconnect pattern by a photolithography technique. An overhanging portion of the anti-reflective film is etched away by a plasma of a Cl.sub.2 /BCl.sub.3 -mixed gas. Then an insulating interlayer is deposited on a resultant semiconductor structure.

Abstract: Connection portions are connected to leads of a capacitor. In this condition, when connection terminals are press-fitted in terminal receiving holes, the capacitor is received in an equipment chamber. A filler is filled in the part chamber, and is solidified, thus completing the assembly. In one alternative, an electronic part, soldered to a printed board, is received within a housing. Each of female metal terminals has an abutment piece, and the abutment piece is abutted against an associated printed line on the printed board in facing relation thereto. In another alternative, the connector housing is divided into two sections, that is, a housing member and a lid, so that the terminal receiving chambers, as well as the electronic part-receiving chamber, is openable. Press-contact terminals 309 are fixedly mounted on and project from a bottom of the electronic part-receiving chamber.

Abstract: An oven for baking a powdered coating material to an object has an inlet air-shield chamber connected to the inlet side of a horizontal heating chamber. The inlet air-shield chamber is provided therein with a radiation heat source which heats the object and the layer of coating powder to a temperature substantially equal to the baking temperature before the object enters the horizontal heating chamber.
