Title: Beam shutter for laser beam
Inventor: MATSUNO TSUKASA
IPC: G02B5/00
Filed: 1988-03-08
Abstract: PURPOSE:To obtain a beam shutter for the laser beam not being reflected toward the beam exit of a laser oscillator by rotating a laser beam reflecting board when the beam shutter is opened and closed. CONSTITUTION:The beam shutter is opened and closed when a reflecting mirror holding plate 5 rotates and crosses the optical path of the laser beam 2. Namely, the title beam shutter is constituted such that the laser beam reflecting board 4 rotates perpendicular to the emitted laser beam when the beam shutter is opened and closed. Consequently, a space required for moving the laser beam reflecting board 4 is decreased to make the shutter compact. Thus, the chamfered part of the laser beam reflecting board 4 never reflects the laser beam toward the exit of the laser oscillator. In addition, the burning of wiring and piping both in the beam exit of the laser oscillator and in the beam shutter can be prevented.

Abstract: PURPOSE:To measure image distortion with high accuracy, by arranging spherical distortion measuring members having high radiation absorptivity and a small diameter to the surface or interior of a plate-shaped support member, which has low radiation absorptivity and high rigidity, in a lattice pattern. CONSTITUTION:A rectangular support member 7 is formed of a material having low radiation absorptivity and high rigidity, for example, a synthetic resin or an acrylic resin. A large number of distortion measuring members 8 are arranged to the surface of interior of the support member 7 in a lattice pattern so that an adjacent interval (d) is provided by required quantity to form an image distortion measuring phantom 6. Each of the distortion measuring members 8 is formed of a material having high radiation absorptivity, for example, a small steel sphere. The diameter of the small sphere is set to about 0.1-5mm and the interval (d) is set to about 5-50mm. Points A'-D' where an image is formed in a distorted state are detected by an image intensifier using the phantom 6 as an object to irradiate the same with radioactive rays from a radiation source and converting said rays to visible light to be compared with points A-D where an image is supposed to be originally formed and image distortions P1-P4 are measured. By this method, image distortion is measured with high accuracy.

Title: Method of making hydrophobic surface of sepiolite
Inventor: SUGITANI YOSHIHIRO
IPC: C01B33/44
Filed: 1990-03-08
Abstract: PURPOSE:To obtain a material for casting dies having superior gas transmittance than casting sand by heating and drying a sepiolite block to make powder, subjecting this powder to further heat treatment to remove water of crystallization, pulverizing, and effecting the reaction with a monohalide silane compd. to change the surface of the sepiolite powder to a hydrophobic surface. CONSTITUTION:Sepiolite blocks expressed by the formula Si12Mg8O30(OH)4(H2 O)4.(6-8)H2O are dried at 100-300 deg.C to make powder. This sepiolite powder is heated at 450-550 deg.C to remove all of the water of crystallization and to change the powder into a state expressed by Si12Mg8O30(OH)4. Then, this pulverized sepiolite powder is allowed to react with a monohalide silane compd. expressed by the formula in an inert gas atmosphere such as gaseous N2. Thus, one or more parts of OH groups on the surface of the sepiolite after calcination are changed into O-Si(R)3 groups. Thereby, the desired sepiolite having hydrophobic surface can be obtained. The monohalide silane compd. above-mentioned is, for example, phenyldimethylchlorosilane.

Title: Method and apparatus for measuring width of spectral line of laser beam source
Inventor: MIYATA HIDEYUKI
IPC: G01J9/04
Filed: 1990-03-08
Abstract: PURPOSE:To use the title apparatus even in a small output laser beam source and to reduce a measuring error by sufficiently delaying one of the split beams of the laser beam source to subject the same to photoelectric conversion and inputting the difference signal of beam outputs to a spectrum analyser. CONSTITUTION:The beam of a laser beam source 2 is split by a beam splitting means 4 and one of split beams is sufficiently delayed with respect to the other split beam by the first and second beam transmission paths 6, 8 sufficiently different in beam path length to input both split beams to an optical coupler 10 and two beam outputs are subjected to photoelectric conversion by a double equilibrium type beam detection circuit 12 and the difference signal thereof is inputted to a spectrum analyser 14. That is, since the photocurrent generated by FM noise determining a spectrum to be measured is multiplied by the double equilibrium type beam detection circuit 12 as compared with a conventional one, the width of a spectral line can be accurately measured even using a small output laser beam source. Further, by the double equilibrium type beam detection circuit 12, an S/N ratio is improved and the harmful AM noise caused by the fluctuation of the amplitude of the beam from the laser beam source is suppressed.

Title: Antiroll device for automobile
Inventor: SUGIYAMA SANJI
IPC: B60G17/015
Filed: 1979-05-08
Abstract: PURPOSE:To improve comfortableness to ride in by a method wherein the upper and lower chambers of the right and left cylinders between a body and each of its side wheels are connected with each other and both the connecting passages are connected with another passage with an open valve which closes by the operation of acceleration. CONSTITUTION:When an automobile turns with its left cylinder 5 on the inside of locus of a rotation, the weight 15 of the valve 10 receives centrifugal force in an arrow direction of A, moves to the outside of the locus of rotation against a spring 17 and shuts an oil hole 19. Therefore, oil pressure appears on the upper chamber 6c of the cylinder 6a lying on the outside of the locus of rotation by the load based on contrifugal force and is transmitted to the lower chamber 5d of the cylinder 5a through the 2nd passage 8. If this oil pressure is greater than the spring constant of a suspension device 3, the cylinder 5 falls, the suspension device 3 moves in harmony with the pressure and the body inclines to the inside of the locus of rotation. It is the same though the car turns in the reverse to the above-mentioned. Therefore, travelling performance becomes more steady and comfortableness to ride in is improved.
