Title: Formation of high tension welded steel tube
Inventor: HANEDA KENJI
IPC: B21D5/12
Filed: 1991-04-17
Abstract: PURPOSE:To provide a forming method to stably manufacture a high tension welded tube in a manufacturing line of a welded tube for continuously rolling and welding a strip metal having a prescribed width. CONSTITUTION:In a breakdown roll being a rough forming process an edge part of a steel strip being a material to be formed is bent to the curvature more than a curvature of a product tube and in a breakdown roll on a cluster roll being an intermediate forming process the center part is bent to the cuvature near the curvature of the tube. The forming loading in the fin pass forming being the finish forming process is reduced as small as possible to dissolve the problem of a roll mark. A remarkable improvement of quality of a welded part can be expected by regulating an amount of squeeze of the squeeze rolls to an adequate amount.

Title: Electrophotographic printing machine
Inventor: TASHIRO TSUNEO
IPC: G03G15/22
Filed: 1978-07-13
Abstract: PURPOSE: To improve the economy of a copying machine by polarizing the laser light from a laser oscillator through a laser modulator in two directions, scanning the light of one direction the original to expose a photosensitive member, scanning the light of the other direction the original in fixing, and employing a laser of low output power without using a half mirror.  
     CONSTITUTION: The laser light from a laser oscillator 14 is polarized through a laser modulator 15 in two directions at different positions with respect to a stationary mirror 16. The first rotary mirror 20 in a first optical system reflects rotatably the light passed from the stationary mirror 16 through first lens group 19 alternatively to a photosensitive member mirror 21 and an original side mirror 22 to allow the light incident to the mirror 21 to irradiate the exposure position of the photosensitive member 1 directly and to allow the light incident to the mirror 22 to scan to expose the original on an original tray 24. Thus, the reflected light is introduced through a condenser lens 25 into a photo receptor 26. The second rotary mirror 28 in a second optical system scans the light passed from the stationary mirror 16 through second lens group 27 on a copy sheet in a passage at P and fixes the image via the laser light.
