Title: Linear pulse motor
Inventor: SAITO SHINICHI
IPC: H02K41/03
Filed: 1988-09-01
Abstract: PURPOSE:To prevent an oscillating phenomenon and to improve accuracy in the stop position by providing grooves in the direction of movement of a moving piece in the pole tooth rows formed in the upperside of two rows of primary iron core with a bias magnet interposed and the underside of the corresponding moving piece. CONSTITUTION:With a bias magnet 2 interposed between stators 4 two rows of the primary iron core 1 is formed. The primary core is further divided in front and behind into 1-c and 1-d forming total four salient poles of the iron core and around each pole a driving winding 3 is wound. On the upperside of the salient poles 1-c and 1-d formed are a pole tooth row 1-a at right angle in the direction of movement of a moving piece 5 and a groove 1b parallel to that direction respectively. Through a rolling member 6 the moving piece 5 is caused to correspond to a stator 1. To the corresponding surface of the moving piece the secondary iron core tooth row 5-a and a groove 5-b are formed as in the primary iron core pole tooth row 1-a and the groove 1-b. The oscillating phenomenon of the moving piece can thereby be prevented and the accuracy in the stop position improved.

Title: Detecting method of dew point of gas laser oscillator
Inventor: TANAKA MASAAKI
IPC: H01S3/00
Filed: 1983-11-22
Abstract: PURPOSE:To eliminate the need for the installation of a sensor for measuring the dew point, and to reduce cost by detecting the dew point by utilizing a phenomenon in which applied voltage remarkably changes by the dew point of a laser gas. CONSTITUTION:The proper dew point of a laser gas extends within a range of -70 deg.C--30 deg.C. Applied voltage for a gas laser oscillator suddenly rises at -70 deg.C or lower as the dew point where the instability of discharge is generated even at constant discharge currents, suddenly drops at -30 deg.C or higher where the efficiency of laser oscillation suddenly lowers, and is kept constant at the dew point to -30 deg.C from -70 deg.C. An I.V detecting section 27 for a dew point detecting section 26 detects discharge current value I from the gas laser oscillator 25 on discharge operation and applied voltage V2 to the I at all times, reads V1 to detected discharged current value I from a memory 28 previously memorizing the relationship of I and V1 to each dew point and compares V2 and V1, and transmits an abnormal signal over a control section 24 when the dew point is displaced from a normal range.

Title: Polarized light separating element and production thereof
Inventor: SHIRAISHI KAZUO
IPC: G02B5/30
Filed: 1990-08-23
Abstract: PURPOSE:To provide the polarized light separating element which has a desired shape and obtain a desired polarized light separating angle by integrally molding two kinds of transparent bodies varying in refractive index to have a specified bearing. CONSTITUTION:Many sheets of transparent thin films 1, 2 which are two kinds of the transparent bodies are alternately laminated. The transparent thin film 1 is formed of hydrogen-contg. amorphous silicon and the transparent thin film 2 is formed of quartz. The hydrogen-contg. amorphous silicon and quartz which have the refractive indices of 3.823 and 1.446 respectively to incident light of 1.3mum wavelength are used. This polarized light separating element is structurally uniform in a direction Y and is inclined by a prescribed angle with the direction perpendicular to the optical main axis, i.e. the lamination plane of the two thin films 1, 2 (the direction optical and unequivocally determined with the molding consisting of the thin films 1, 2) in the Z direction which is the incident direction of the light. The incident polarized light in the direction inclined with the optical main axis is separated to ordinary light and extraordinary light by the double refractiveness occurring in the structure consisting of two kinds of the transparent bodies. The polarized light separating angle formed of both the light rays is larger as the difference in the refractive index between two kinds of the transparent bodies is larger.

Title: Wiper device
Inventor: SUZUKI TAKAHIRO
IPC: B60S1/34
Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To provide a wiper device which does not move easily, even if an outer force is applied at the stop time of a device, without hurting the merrit of the wiper device of both swing type constituted in a small and light shape. SOLUTION: A wiper device 10 is formed in both swing type connected a crank arm 72 to pivot levers 24, 26 respectively by a pair of link rods 76, 78. Respective link rods 76, 78 and crank arm 72 are set in an arrangement relation positioning on nearly one straight line at the stop time of the wiper device. Therefore, even if an outer force is transmitted to the crank arm 72 through the pivot levers 24, 26 and link rods 76, 78, this outer force does not act to a right angle direction for the crank arm 72. Accordingly, the wiper device 10 is not moved easily by the outer force, without the rotation of the crank arm 72 by the outer force.
