IPC: B23Q15/22
Filed: 1987-03-28
Abstract: PURPOSE:To eliminate a trial machining work, by a method wherein a tool for machining attached to a tool rest is moved forward to a measuring member, e.g. master works, from a difference between the forward movement stroke and a preset given stroke amount, a correction value is computed, and the computing result is inputted to NC control data. CONSTITUTION:By a CPU, a tool rest 14 is moved forward toward a master work 9 through a tool rest drive circuit, and a position allowing the tip of a bite 15, serving as a tool for machining, to allow contact of it with the master work 9 is determined by the change in current of the tool rest drive circuit. A difference between a forward movement stroke from the contact position and a given forward movement stroke amount preset by an RAM is inputted as a correction value in the NC control data area of the RAM. Thereby, a trial machining work, heretofore needed, is completely eliminated, and a bite mounting error can be corrected through a simple method.

Title: Liquid crystal video projector
Inventor: HASHIZUME TOSHIAKI
IPC: G02F1/13363
Filed: 1991-04-09
Abstract: PURPOSE:To suppress rereflected light from a liquid crystal panel, a polarizing plate, and other surface and to improve the contrast of picture quality by inserting a 1/4lambda wavelength plate between a light-projection side polarizing plate and a projection lens. CONSTITUTION:The 1/4lambda wavelength plate 5 is inserted between the light- projection side polarizing plate 4 and projection lens 6 and then light transmitted through the polarizing plate 4 passes through the 1/4lambda wavelength plate 5; and part of the light is reflected by the projection lens 6 and passes through the 1/4lambda wavelength plate 5 again. Thus, the light passes through the 1/4lambda wavelength plate 5 twice in total to have its axis of polarization rotated by 90 deg. and the light is not transmitted, but absorbed when entering the polarizing plate 4 again. Consequently, the light striking on the liquid crystal panel 3 with a high reflection factor is not reflected to exit from the projection lens 6. Here, the 1/4lambda wavelength plate 5 may be inserted between the liquid crystal panel 3 and light-projection side polarizing plate 4 and a multi-layered reflection preventive film may be formed on the constituent lens surface of the projection lens 6 having a surface reflecting light arriving from the liquid crystal panel 3 to the liquid crystal panel 3 again.
