Title: Method for coating electrophotographic photoreceptor
Inventor: IGAWA OSAMU
IPC: B05D1/18
Filed: 1993-10-20
Abstract: PURPOSE:To form a uniform coating film on the surface of a substrate without forming a coating film in the substrate by saturating the internal space of the substrate with the vapor of the solvent of a coating soln. before the cylindri cal substrate is dipped in the soln. CONSTITUTION:A hollow cylindrical substrate 1 with both ends opened is held by a holding part 2 connected liftably to the main body of a coating device, the upper end of the substrate 1 is closed to prevent the flowing of a gas out of the inside. A hole 3 for jetting a solvent is formed in the holding part 2. For example, 1.5 pts.wt. of oxytitanium phthalocyanine, 1.5 pts.wt. of 'Butyrol #3000K(R)' made by Electrochemical Co., 97 pts.wt. of tetrahydrofuran are agitated and dispersed to form a coating soln. 4, the lower end of the substrate 1 is set at a position 10 mm from the coating soln. surface, and tetrahydrofuran is jetted from the hole 3 and vaporized. The substrate 1 is dipped in the soln. 4, then pulled up and coated. Consequently, bubbles are not generated from the lower end of the substrate, and a uniform coating film is obtained.

Title: Waveguide grating element
Inventor: ARAI HIDEAKI
IPC: G02B6/12
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To embody characteristics which do not depend upon temperature without using electric power by sticking a metallic plate which generates strain in a substrate in such a manner that the dependence of the Bragg wavelength of gratings on temperature attains a specific value or below. SOLUTION: The waveguide grating element formed with the gratings 9 in the waveguides 8a and 8b on the substrate 1 is constituted by sticking the metallic substrate 10 which generates the strain in the substrate 1 in such a manner that the dependence of the Bragg wavelength of the gratings 9 on temperature is confined to <=0.001 nm/ deg.C. When the temperature of the quartz substrate 1 changes from 25 deg.C, warpage occurs in the waveguide grating element and the waveguide (core2) is shrinked in the stress direction when the temperature is high, thereby the strain is generated in the gratings 9. The periods of the gratings 9a and 9b are shortened by the generation of the strain, by which the influence of the increase in the refractive index with an increase in temperature is offset. The waveguide grating element which does not depend upon temperature may thus be embodied.

Filed: 1990-09-29
Abstract: PURPOSE:To permit an easy and accurate adjustment of the amt. of coating material and control the occurrence of streak or the like by a method wherein a blade is held by a holder, a pressure is exerted on the rear edge of the blade and this pressure is applied directly to the edge face thereof without causing its deflection. CONSTITUTION:A blade 1 having an inclined edge face is held between the two sides of a blade holder 2 in a slidable manner. The blade holder 2 is provided with an adjusting screw 8, which exerts an adjustable pressure on the rear edge of the blade 1. The blade holder 2 is secured on a coating device so as to make the end face of the blade 1 movable along coating surface. As a result, the pressure exerted on the rear edge of the blade is applied directly to the edge face to permit an easy and accurate adjustment of the amt. of coating material. By this method, a small bevel angle phi can be easily set, whereby the occurrence of streak or the like can be controlled.

Filed: 1993-10-20
Abstract: PURPOSE:To provide a pole display plate which is easy to make mounting operation and has an effect of preventing bill sticking and a process for easily producing this pole display plate and a metal mold used therefor. CONSTITUTION:The pole display plate 1 is formed by molding a rectangular sheet 3 made of a polyvinyl chloride resin into a shape curved to be a cylindrical shape. Plural projections 5 integrally formed by plastically deforming the sheet 3 are formed at prescribed intervals on its outer peripheral surface and plural pieces of reflection tapes 7 are diagonally stuck thereto.

Consequently, the sheet 3 has a shape curved to be the cylindrical shape and the projections 5 are integrally formed by the projecting parts of the suction metal mold. The height of the projecting parts of the metal mold are individually adjustable. The projections 5 are not formed in the positions where reflection tapes 7 are stuck by merely holding the projecting parts retracted.

IPC: E02D17/20
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To improve workability by fixing a base plate on which a plurality of supports are erected on a hard slope face by fixing pins and attaching a collapse prevention material of the vegetation base board to the supports. SOLUTION: Strip base plates 21 for instance where a plurality of supports 20 are erected on a hard slope face 10 such as a lining concrete, a rock bed, etc., are continuously fixed by fixing pins 22 and the supports 20 are arranged staggeringly. Subsequently, A collapse-prevention material 30 made of reginous or metallic strip net is spread over to form a plurality of sections 31. The outermost periphery is connected to the supports 20 to surround the collapse- prevention materials 30. Then, the base plate 21 may be stuck to the slope face 10. In this way, since the number of pins in use and the number of driving times can be reduced, the construction period and cost can be reduced. Further, a greening base boad can be constructed if the base plates are stuck, even on a concrete slope face where anchors are prohibited from using it.
