Title: Apparatus for detecting position of moving body
Inventor: TSUMURA TOSHIHIRO
IPC: G01C15/00
Filed: 1986-04-04
Abstract: PURPOSE:To simplify a mechanism to achieve miniaturization and wt. reduction, by allowing laser beam to reciprocate in the shaft of a rotary encoder. CONSTITUTION:The laser beam emitted from the laser diode 1 provided at one side of the shaft 6 of a rotary encoder 5 passes through the shaft 6 to be guided to the other side thereof and emitted to a revolving direction. The laser beam is reflected from three corner cubes CC arranged at predetermined places so as to be separated from a moving body to pass through the shaft 6 reversely and passes through a beam splitter 3 to be subsequently inputted to an interruption controller 32 as a beam receiving signal (a). The encoder 5 detects an angle of rotation to output an angle signal (b) and the positional informations of the corner cubes CC are taken in CPU34 set to a keyboard 42. CPU34 operates the position and azimuth of the moving body from three positional informations of the cubes CC and the angle signal. As mentioned above, because of the mechanism allowing beam to reciprocate in the shaft 6, an optical meter is made compact.

IPC: C08L67/00
Filed: 1990-03-27
Abstract: PURPOSE:To orient the fine crystals of dyestuffs at a high degree by developing a specified soln. on a substrate to form the film thereof, then putting a straight streak on this film and allowing the crystals to grow in the direction orthogonal with the streak before the formation arises. CONSTITUTION:Poly-epsilon-caprolacton (PCL) and para-nitroaniline (p-NA) are dissolved in an org. solvent to prepare the soln. This soln. is dropped onto a rotating slide glass by which a spin coated film is formed. The film is stripped in the form of a straight line at 2mm width by a fluoroplastic piece to form the streak after the film is formed and before the nucleation of the PCL/p-NA takes place. Consequently, the many nucleus are formed along the streak and the crystals are grown in the direction perpendicular to the streak therefrom.

Title: Optical pickup device
Inventor: FURUHATA HITOSHI
IPC: G11B7/09
Filed: 1992-02-28
Abstract: PURPOSE:To reduce bad influence due to the generation of an offset in push-pull method. CONSTITUTION:A parallel plate 16 is arranged in front of a photodetector 4 and the detection face of the photodetector 4 is arranged so that the diffraction pattern of a reflected beam is focused on an ellipse rotated by 90 deg..
