摘要： A polyester film for printed circuits to be used as a base in a printed circuit base plate or as a base and/or cover layer in a printed circuit board, which undergoes a degree of dimensional stability of not more than 1% in both the longitudinal and transverse directions when kept at 150.degree. C. for 30 minutes, and which is obtained by heat treating an extrusion molded and stretched polyester film at 150.degree. C. to 240.degree. C. without applying tension.

摘要： An apparatus for measuring an optical axis direction in which an intensity of the light transmissive to a specimen to be measured disposed between two polarizers is measured by an orthogonal Nicol optical system which uniaxially comprises a light source, said two polarizers, and a light receptor thereby determining the optical axis direction of the specimen to be measured. The apparatus comprises a conveyor for continuously moving the specimen in an elongated form in the direction intersecting with the orthogonal Nicol optical system at a right angle. An intensity of the transmissive light is measured during the period of time when the specimen is fed from one side of a casing, and removed from the other side of the casing. The casing encases the optical system.

摘要： A peeling type developing method and apparatus for removing exposed photoresist from printed circuit boards. The printed circuit board is covered with a photopolymerization compound layer and then a transparent support layer. After exposure, a thin adhesive tape is stuck to the support layer extending obliquely across the board and crossing opposite corners thereof. The adhesive tape, together with the support layer and the unexposed portions of the photoresist material, are peeled off the printed circuit board by a pair of pinch rolls with the aid of a peeling bar in line contact with the substrate through the adhesive tape and the support layer.
