Title: Image sensor
Inventor: YAKUSHIJI NOBUO
IPC: G01B11/02
Filed: 1984-06-02
Abstract: PURPOSE:To obtain a portable image sensor which can adjust easily a focus and can measure an object to be measured at an optional position, by providing a light source, the first optical system, the second optical system whose focal position is variable, and a focusing function for interlocking these focal positions to each other. CONSTITUTION:A lens system 13 for forming an image of a reflected light of an object to be measured 12 is provided on an opening part of a housing 11, and also this image sensor is constituted of a uniaxial solid-state image pickup element 14 placed in an emitting side of the lens system 13, a half mirror 15, a light source 16 placed in the reflecting direction of this mirror 15 so that an optical path from the lens system 13 becomes equal to an optical path to the element 14, and a focusing mechanism 17 which adjusts a focus of the lens system 13, or adjusts a distance between the lens system 13 and the object 12. According to this constitution, a light projected from the light source 16 is reflected by the mirror 15, and a light spot is projected onto the object 12 on an extension of its optical axis by the lens system 13. Accordingly, the present position of the image sensor can be known exactly by confirming visually the light spot. Also, when the light spot is converged to the object by adjusting the mechanism 17, the reflected light from the object 12 forms an image exactly on the element 14.

Title: Antistatic synthetic resin molding dissipating static charge
Inventor: NAKAI TADATOSHI
IPC: B65D85/86
Filed: 1988-05-10
Abstract: PURPOSE:To obtain the title colorable composition good in dispersion of antistatic agent, improved in moldability and freed from chipping-off of antistatic agent, by dispersing an antistatic agent comprising a specified metal oxide and a dispersing agent comprising a specified metal oxide in a synthetic resin and molding the obtained mixture. CONSTITUTION:The title molding is forming by dispersing at least one antistatic agent selected from among SnO2, SnO, ZnO, Bi2O3, barium titanium oxide, germanium and silicon and a dispersing agent selected from among TiO2, ZnO, Al2O3 and SiO2 in a synthetic resin and molding the obtained mixture. By filling with said electroconductive antistatic agent, the volume resistivity of the molding can be decreased, and the relaxation time of electric charges can be shortened and can be set at such a value as not to be influenced by the potential change of the external environment; by the addition of said dispersant, the antistatic agent can be homogeneously in the molding, and therefore the dispersion of the volume resistivity can be decreased, and the antistatic agent can be prevented from being concentrated on the external surfaces, especially, the rear and therefore the chipping-off of the antistatic agnet from the rear can be prevented; and further because of its light color, it can be easily colored with any desired color.

Title: Vacuum exhaust device and vacuum exhaust method
Inventor: OKUMURA KATSUYA
IPC: H01L39/24
Filed: 1989-05-09
Abstract: PURPOSE:To improve the exhaust characteristics of gas having a low molecular weight, especially a water molecule by a method wherein a heat exchanger cooled by a helium freezer to freeze and collect gas molecules is disposed on the suction port side of a turbomolecular pump. CONSTITUTION:When vacuum exhaust is effected with the aid of only a turbomolecular pump 26, residual gas in a vacuum vessel 21 contains quantities of light gas. Therefore, by freezing and collecting water molecules by a heat exchanger 25 cooled by a helium freezer 24 on the suction side of a turbomolecular pump 26, exhaust performance is improved, and vacuum having good quality and the high degree of vacuum can be generated. By also cooling small gas, e.g. hydrogen, helium, having a molecular weight not frozen and collected by means of the heat exchanger 25, temperature is reduced and a gas molecular speed is decreased. As a result, a blade velocity ratio is increased, and exhaust performance of the turbomolecular pump 26 is improved. Conventional poor exhaust performance for gas having a small molecule, especially a water molecule can be eliminated.

IPC: B21B45/02
Filed: 1978-09-21
Abstract: PURPOSE: To considerably reduce the quantities of bends of the wide flange beams by beforehand force cooling both side flange parts under the specific conditions at the time of feeding the slabs of the specified length having been hot rolled in H-form posture to a cooling device.  
     CONSTITUTION: The wide flange beams having been hot rolled and cut to the specified length are run in an H-form posture on a line table 6, and cooling water is sprayed from nozzles 3, 3 of headers 5, 5 opposedly disposed on both sides of the table. The respective slabs 1 having been force cooled are parallel disposed in the cooling chamber in the I-form posture having rotated 90°, but spacings between the adjoining slabs, temperature differences between the respective slabs and the differences in cutting length give influence to each other and therefore the rates of cooling of the right and left flange parts differ, producing bends in the lengthwise direction. Hence, the quantities of the bends are beforehand estimated through calculation or actual measurement and the rate of flow of the cooling water, the positions of its spraying to the flange parts and the rotating speed of table rollers 8 are so adjusted as to offset the quantities of the bends.

Title: Pattern forming method
Inventor: SAEKI HIDEO
IPC: G03F7/039
Filed: 1979-09-07
Abstract: PURPOSE:To further enhance the minute pattern formability of a tertiary butyl methacrylate polymer or a copolymer contg. tertiary butyl methacrylate without lowering the sensitivity by heat treating the (co)polymer under specified conditions. CONSTITUTION:A tertiary butyl methacrylate polymer or a copolymer contg. tertiary butyl methacrylate as a radiation sensitive positive type resist is heat treated at about 200 deg.C, exposed, and developed. The solubility of the (co)polymer in a developer is changed by the elimination of tertiary butyl ester groups due to the heat treatment, and a developer of high solubility can be used, so high sensitization is enabled. High sensitization results in a resolution lowering. The minute pattern formability of the (co)polymer can, however, be improved remarkably without lowering the sensitivity by carrying out heat treatment at 180-270 deg.C in an oxygen- contg. atmosphere.
