Filed: 1991-04-03
Abstract: PURPOSE:To obtain a multi-beam scanning device which has simple constitution and can draw a specially smooth image having high print quality by controlling the diameter of a laser beam. CONSTITUTION:The laser beam emitted by a semiconductor laser element 2 has its polarizing direction changed by a PLZT element 4 and is split by a polarization beam splitter 9 into laser beams 18 and 19.

Abstract: PURPOSE:To form a character excellent in chemical resistance and heat resistance, by a method wherein a green sheet is bonded to a substrate in such a state that the paste printing surface thereof is made inside and sintered to be transparentized and laser beam is allowed to irradiate the substrate on the side of the green sheet to form a character. CONSTITUTION:Paste 15 consisting of glass, inorg. pigment and an org. binder is printed on a green sheet 10 obtained by stretching a kneaded mixture of glass or ceramics and an org. binder into a sheet shape and the green sheet 10 is bonded to a substrate 1 composed of a metal, glass or ceramics so as to bring the printed surface thereof in the inside and sintered. Laser beam is allowed to irradiate the substrate 1 on the sintered transparentized green sheet 10 and the paste 15 between the green sheet 10 and the substrate 1 is melted and scattered to form a character B at the irradiated part. Since the character B thus formed is not exposed to the surface of the green sheet 10, said character B is not directly brought into contact with the open air and can be made excellent in chemical resistance and heat resistance.
