Title: Optical scanner
Inventor: ITABASHI AKIHISA
IPC: B41J2/44
Filed: 1989-08-01
Abstract: PURPOSE:To obtain a wide usage mode by selecting whether or not a field curvature compensating means is operated with a changeover switch. CONSTITUTION:When a low-density optical scan is selected with the changeover switch, the field curvature compensating means is put in a nonoperation state automatically since a light spot has a little variation in spot diameter. When a high-density optical scan is made, an aperture stop control means 9 is put in operation with the changeover switch to vary the opening width of an aperture stop. The field curvature compensating means 8 is put into operation through the operation of the changeover switch 10 and the curvature field is compensated by displacing a cylindrical lens 2 in the optical axis direction. Consequently, the curvature of field in the subscanning direction can easily and securely be removed at the time of scanning with high-density. Further, when a fast optical scan is made, the low-density optical scan can easily be made without any field curvature compensation.

Abstract: PROBLEM TO BE SOLVED: To provide a cylinder for a molding machine in which a working man-hour is reduced and shrinkage fitting work is made easy and fracture of an inner layer member near to the end part on the outlet side is prevented and also generation of a crack in an external cylinder is prevented.

Abstract: PURPOSE:To restrain unintentional radicals from being generated, to increase an energy selective property, to speed up etching-rate and to execute a treatment under a high gas pressure by providing a laser oscillator which again activates semistable molecules which are supplied to an object to be treated from a passage hole in an electrode. CONSTITUTION:When a voltage across individual electrodes 30, 31 reaches a prescribed level, a glow discharge is generated across the electrodes 30, 31 and, e.g. fluorine radicals F* are generated. The radicals F* are passed through individual holes in the mesh of the anode electrode 31 and are supplied to a semiconductor wafer 22. Since the radicals F* are passed through only the individual holes in the mesh of the anode electrode 31 in this case, most of the radicals F* are supplied to the semiconductor wafer 22. When the semiconductor wafer 22 is formed of Si at this time, it is etched as SiF4. In this case, the life of the radicals F* which have been passed through the mesh of the anode electrode 31 is at about 0.1 to 1musec. When the radicals which have been passed through the mesh of the anode electrode 31 are irradiated with a laser beam from a laser oscillator 61, the life of the radicals F* is lengthened up to the order of msec. That is, the radicals are changed again to radicals.
