Abstract: PURPOSE:To obtain a product having abrasion resistance in spite of a thin pattern layer, generating no warpage and having a high non-directional design effect by forming a pattern layer composed of a molten mixture of a white inorg. powder and a colored thermoplastic resin powder on a base material. CONSTITUTION:A base sheet 1 is passed through calender rolls 2, 2' and kept at a surface temp. of 150-220 deg.C. A resin composition powder 4 wherein a colored thermoplastic resin, for example, colored polyvinyl chloride and 3-70wt.%, pref., 10-50wt.% white inorg. powder with a particle size of 0.2-20mum such as aluminum hydroxide, alumina, quartz or talc is supplied from a hopper and sprayed on the base sheet 1 by a sprayer 5. After spraying, the base sheet 1 is heated, melted and rolled along with the pattern of the powder 4 on the sheet 1 by calenders 6, 6'. Since the pattern is composed of a thermoplastic resin powder, a non-directional pattern is obtained even under a rolling condition and no pattern unwantedly elongated is generated.

Title: Measuring method for retardation
Inventor: NAGATA SHINICHI
IPC: G01N21/23
Filed: 1992-12-29
Abstract: PURPOSE:To improve the accuracy of the measurement of retardation by rotating a wavelength plate with respect to a sample, searching the direction where the retardation becomes maximum, and detecting the direction of the optical axis of the sample. CONSTITUTION:A wavelength plate 14, whose retardation and the bearing of an optical axis are known, is overlapped on a sample S and placed between a polarizer 1 and an analyzer 2. The overlapped sample S and wavelength plate 24 are rotated. Action for obtaining the maximum and minimum intensities of the transmitted light is performed. For example, when the vicinity of the integer times of 2pi for the retardation of the sample S is considered, the retardation changes in the range from about +pi/4 to -pi/4 when the overlapping direction is changed at the time when the 1/4 wavelength plate 14 is overlapped. Therefore, when the wavelength plate 14 is rotated with respect to the sample S and the direction where the retardation becomes maximum is searched, the sample S agrees with the optical axis of the wavelength plate 14. Since the direction of the optical axis of the wavelength plate 14 is known beforehand, the direction of the optical axis of the sample S is found.

Inventor: HATTORI TAKAHISA
IPC: B05D7/00
Filed: 1992-12-11
Abstract: PURPOSE:To enable to cover the depressions of the cut surface, especially the tilted or vertical cut surface, of the foamed concrete panel with an uniformly thick coating film by applying an electrostatic coating to the surface of a cut surface-having foamed concrete panel. CONSTITUTION:A foamed concrete panel 1 is horizontally loaded and carried on a roller conveyor earthed on the side of an anode, and the decorative joint side of the concrete panel is electrostatically coated during the carrying process. Therein, a coating having a viscosity of 2-40 decipascal is used, and the coating is applied until the depressions of the cut surface are perfectly covered with the coating.

Title: Discharge-pumped excimer laser apparatus
Inventor: KUWABARA TAKUYA
IPC: H01S3/038
Filed: 1992-12-21
Abstract: PURPOSE:To obtain the beam pattern having the uniform distribution of the intensity of light by making the surfaces of main electrodes flat, arranging insulators having the approximately equal dielectric constant effectively as that of the main electrodes with an electric field on both sides, making the surfaces of the insulators to be the same plane as the surfaces of the main electrodes. CONSTITUTION:The surfaces of main electrodes 2 and 3 are made flat. Insulators 8 and 9 and 10 and 11, whose surfaces are also flat, are arranged on both sides of the main electrodes. The surfaces of the main electrodes 2 and 3 and the insulators 8 and 9 and 10 and 11 are made to be the same plane. The dielectric constants of the insulators 8 and 9 and 10 and 11 are effectively equal to the dielectric constant of the main electrodes 2 and 3. Therefore, the electric line of force becomes orthogonal with respect to the surface. Since the electric line of force is orthogonally inputted into the main electrodes 2 and 3, the uniform distribution is obtained. Therefore, discharge current does not flow through the insulators 8-11. Thus, the boundary of the discharging region is definitely marked. As a result, the laser beam pattern having the uniform distribution of the light intensity can be realized.
