Title: Optical tube
Inventor: EDOWAADO JII RUDOUITSUKU JIYUN
IPC: C08L101/00
Filed: 1989-07-20
Abstract: PURPOSE: To obtain a durable optical tube which shines uniformly all over and is easy to handle by coating a core contg. polymer particles as a light diffusing agent in a synthetic resin matrix with an outer layer of a transparent synthetic resin. CONSTITUTION: A core contg. particles of an org. high molecular compd. such as polyalkyl acrylate as a light diffusing agent in a synthetic resin matrix is coated with an outer layer of a transparent resin optionally mixed with additives such as a flame retardant, a dye and a heat stabilizer to obtain the objective durable optical tube easy to handle. When light is introduced into this optical tube from one end, it is scattered by the light diffusing agent and passes through the outer layer or returns to the inside of the core by total reflection from the boundary between the core and the outer layer and the entire optical tube shines.

Title: Tachometer
Inventor: NISHIMURA TETSUJI
IPC: G01P13/04
Filed: 1984-09-05
Abstract: PURPOSE:To obtain a small-sized and highly accurate tachometer reducing influence due to the eccentricity of a radiation grating by making the diffracted light obtained from light flux made incident upon the radiation grating formed on the periphery of a disc again incident upon the radiation grating to diffract the incident light and reducing the load of a rotary substance to be tested. CONSTITUTION:Light flux is made incident from a light source 1 upon the radiation grating 5 obtained by forming a grating pattern consisting of light transmission parts and reflection parts on the periphery of the disc at equal angles. Two diffracted light rays having specific degrees out of the diffracted light reflected and diffracted by the radiation grating 5 are reflected by reflectors 41, 42, 41', 42' and the reflected light rays are again made incident upon a position of the radiation grating 5 which is approximately point-symmetrical with the incident position of the initial light flux about the rotation center of the rotary substance. The two diffracted light rays diffracted again and having specific degrees are superposed, divided into two light flux components by a polarized beam splitter 8 and then detected by two photodetecting elements 9, 9'. The outputs of the elements 9, 9' are differentially amplified and the amplified output is converted into a binary value through a comparator or the like. The binary signal is analyzed at its frequency to find out the frequency, so that the displacement of the rotation speed of the rotary body can be obtained on the basis of the frequency.

Title: Formation of low resistance current path between buried contact and diffusion region and semiconductor device containing such buried contact
Inventor: MAATEIN SHII ROBAATSU
IPC: H01L29/41

Title: Retrieving device for disklike recording medium
Inventor: MIAMA TORU
IPC: G11B21/08
Filed: 1992-07-14
Abstract: PURPOSE:To accurately retrieve a desired recording position. CONSTITUTION:An output from an optical pickup 5 fed through a high frequency amplifier 6 is input from a line L1 to a counter 20 as a track cross pulse through contacts 18b, 18a of a changeover switch 18. If the cross pulse is absent during retrieving for selecting a song or reproducing at random, a flaw detection signal is output from a flaw detector 14 thereby to make the contacts 18a and 18c of the switch 18 conduct to input a pseudo-pulse from a clock generator 19 to the counter 20. Accordingly, since the cross pulse or the pseudo-pulse is input to the counter 20 irrespective of the presence/absence of the flaw, the retrieving operation can be accurately executed without miscounting the number of tracks.

Title: Variable direction optical isolator
Inventor: TAKARA HIDEHIKO
IPC: G02B27/28
Filed: 1990-07-16
Abstract: PURPOSE:To control a forward direction and a backward direction electrically by using a rotary polarizer whose rotary polarizing property is changed electrically. CONSTITUTION:Light from an optical fiber F1 transmits only specific polarized light by a polarizer P1. The polarizing direction of transmitted polarized light is rotated by 45 deg. by a Faraday rotor FR, and is made incident on the rotary polarizer R. Since a voltage is applied to the rotary polarizer R by a voltage source V, the polarized light emitted from the rotary polarizer R is made incident on an analyzer P2 as keeping the polarizing direction. Since the polarizing direction of the polarized light coincides with the transmission polarizing direction of the analyzer P2, the polarized light transmits the analyzer P2, and is coupled with an optical fiber F2. In a case opposite to where the voltage is applied to the rotary polarizer R, the light from the optical fiber F2 is shielded by the polarizer P1, and no coupling with the optical fiber F1 occurs. When no voltage is applied to the rotary polarizer R, the polarizing direction of the light from the optical fiber F1 is rotated by 90 deg.. The polarized light is shield by the analyzer P2, and no coupling with the optical fiber F2 occurs. In a case opposite to when no voltage is applied to the rotary polarizer R, the light from the optical fiber F2 is coupled with the optical fiber F1.

Abstract: PROBLEM TO BE SOLVED: To reduce cost while maintaining high accuracy by generating the converging-diverging state of two luminous flux caused by temperature fluctuation in a direction of suppressing the fluctuation of interference fringe spaces. SOLUTION: The grating array direction of a diffraction grating G3 is the same as that of diffraction gratings G1, G2, and the grating pitch is equal to the grating pitches of the diffraction gratings G1, G2 and equal to twice the pitch of interference fringe in a position of distance (c) of diffracted light respectively outgoing from the diffraction gratings G1, G2. Glass material is used as the material of the diffraction grating G3 so that the grating pitch is not substantially fluctuated, thus preventing measuring accuracy from depending on environment. Minus primary light and plus primary light generated by diffraction of plus primary light and minus primary light from the diffraction gratings G1, G2 always join so that the wave fronts coincide with each other, and outgo as interference luminous flux from the diffraction grating G3, and a light detector 9 detects this.  In association with the movement of the diffraction grating G3, periodic signals generated in a cycle of half pitch of the grating pitch of the diffraction grating G3 are stably generated, and a signal processing circuit measures the relative displacement quantity.
