Title: Polarimetry plate for laser light beam and polarimetric method using it
Inventor: SUZUKI MASAHIRO
IPC: G01J4/00
Filed: 1989-05-12
Abstract: PURPOSE:To accomplish a simple polarimetric operation appropriate for an operating field by forming and cutting a polarimetry plate which is obtained by attaching a thin metallic plate to the upper surface of an acrylic plate. CONSTITUTION:An iron plate 3 is attached to the acrylic resin plate 5 to obtain the polarimetry plate 1, which is fixed on the table of a laser beam machine. When the plate 1 is cut from its end face in an optional direction by irradiating the plate 1 with a laser light beam L, the metallic plate is heated and the acrylic plate is vaporized, so that a recessed part is formed. When the laser light beam is circularly polarized light, the cross-sectional shape of the recessed part gets symmetric. When it is elliptically polarized light, the corss-sectional shape other than the shape obtained by being cut in the major and minor axes direction gets symmetric. Thus, the extent of polarization is qualitatively decided.

Title: Ball screw
Inventor: SAKAMOTO YOSHIHITO
IPC: F16H25/24
Filed: 1982-07-09
Abstract: PURPOSE:To increase the lead angle of a ball screw with a simple structure by inclining radial roller bearing in which part of the inner periphery of the inner wheel is engaged within the valleys of a threaded shaft, along the lead angle of the valleys and mounting it in a housing. CONSTITUTION:When a threaded shaft 2 rotates, the parts which are engaged with the valleys 1 on the inner periphery of inner wheels 4a,4b, 4c of bearings 5a, 5b, 5c are guided via the valleys 1 to move along the shaft 2. Simultaneously, the inner wheels 4a, 4b, 4c are rotatably driven by the shaft 2, and a housing 3 is moved along the shaft 2 without rotating around the shaft 2. Since the structure thus becomes extremely simple and the threads are not cut in the housing, the iclination of the bearing can be made coincident to the lead angle even if the lead angle alpha of the valleys is large or small to freely correspond to it. Accordingly, the lead angle of the valleys can be freely selected in a wide range, and any restriction is unnecessary.
