Title: Slit exposure device
Inventor: HIROSE YOSHITSUGU
IPC: G03B27/54
Filed: 1984-08-03
Abstract: PURPOSE:To improve illumination efficiency with an illumination of a light collection section set to a high value even with a light source consuming low power by permitting light to be condensed on an original surface using a condenser lens and a reflector at respective first and second apertures of illuminating means. CONSTITUTION:Illumination light, which is emitted from an aperture formed by removing portions of a reflection film and a phosphor coating of a fluorescent lamp 15 as a light source in the longitudinal direction of the tube wall, is condensed on a condensing area M of the surface of an original 2 through a cylindrical lens 19, while illumination light from a second aperture 16b is reflected by a reflector 18 before being condensed on the condensing area M. Thus, the illumination light is efficiently condensed on the condensing area M having a small width dimension. It is thus possible to set a sufficiently high illumination degree on the original surface condensing area using the fluorescent lamp 15 which consumes low power. Thus, the illumination efficiency can be improved.

Title: Image-receiving body for thermal transfer recording
Inventor: IMAI AKIHIRO
IPC: B41M5/52
Filed: 1985-07-24
Abstract: PURPOSE:To obtain an image-receiving body having large heat resistance and dyeing properties and having a dyeing layer free from bleed of dye, by forming on a substrate the dyeing layer containing a resinous cured substance of specific polyester urethane acrylate resin. CONSTITUTION:A dyeing layer containing a resinous cured substance of polyester urethane acrylate resin expressed by the formula [I] (where R1 denotes -H or -CH3, R2 a residual group of dihydric alcohol, R3 a residual group of organic di-isocyanate, and R4 a residual group of polyester which contains hydroxide groups at both ends of a molecule respectively and whose molecular weight is 3,000 or less) is provided on a substrate. In the formula [I], the structure of -O-R4-O- has a dyeing power and gives flexibility also to a cured substance, and so high dyeing properties can be obtained. Moreover, since the flexibility of the cured substance is not very large when the molecular weight of R4 is 3,000 or less, the occurrence of bleed and the lowering of heat resistance can be held down. A cured substance prepared by adding a reactive monomer or a reactive oligomer of various kinds to the polyester urethane acrylate resin is effective especially for an improvement of the heat resistance and others.

Abstract: PROBLEM TO BE SOLVED: To improve the detection sensitivity of an angular velocity by supporting one edge of a vibrator with a fixed member, providing a distortion detection means at the edge, and detecting the distortion of a vibrator due to Coriolis force. SOLUTION: A drive force due to Lorentz force is generated at a magnet 12 due to a coil 20, the vibration displacement between a vibrator 11 being vibrated by a photo reflector 21 and the magnet 12 is optically detected, and a coil current is controlled stably with a constant amplitude. When a swing is applied to the vibrator 11 around z axis through a pedestal 18, a Coriolis force that is proportional to a mass, an excitation piece, and an angular velocity Q is generated in x-axis direction. The Coriolis force is transferred to a detection piece 11b via a flange (c) and the detection piece 11b is distorted in x-axis direction.  An electric charge being generated at piezoelectric ceramics 13 and 14 being provided near the fixed edge of the detection piece 11b is taken out as a signal, thus obtaining the angular velocity Q around z axis, thus improving sensitivity and stability for detecting the angular velocity Q.
