Title: Diffusion plate
Inventor: YOKOYAMA KAZUAKI
IPC: G09F9/00
Filed: 1989-08-30
Abstract: PURPOSE:To brighten the diffusion plate and to uniformize the luminance distribution thereof by constituting the diffusion plate by superposing and disposing diffusion plate body and a transparent plate formed with many circular conical projections on the surface on the side opposite from a light source. CONSTITUTION:The diffusion plate is constituted of the light source 1, a reflecting plate 2 and the diffusion plate body 3 consisting of a milky white plate or embossed plate, etc., dispersed with the diffused grains of inorg. matter. The circular conical projections 11 are formed on the surface of the planar transparent body 10 disposed in front of the milky white plate 3 on the side opposite from the light source. The light diffused by the milky white plate 3 is, therefore, refracted by the slopes of the circular conical projections 11 of the transparent plate 10 and is then passed therethrough. Since this refraction is the refraction toward the center line direction of the circular conical projections, the refraction is the direction where directivity is provided in the diffused light. Further, the refractive effect is imparted to the rays emitted from any directions of the circular conical projections 11 and, therefore, the varying of the visual fields with the directions is obviated. The brighter diffusion plate is obtd. in this way and the luminance distribution is uniformized.

Title: Monitor pulse generating circuit for transmission line changeover state
Inventor: TAKEMURA TAKENAO
IPC: H04L12/42
Filed: 1991-09-03
Abstract: PURPOSE:To generate a monitor pulse with a circuit of a small sized scale by detecting an edge of an output resulting from selecting a trailing/leading of a path changeover pulse by an edge selection means. CONSTITUTION:In the case of changeover of a transmission line, a transmission line changeover state monitor pulse in a 1-bit width is generated and whether or not an oscillation state is entered is monitored by monitoring the pulse. In this case, when the transmission line changeover state monitor pulse is generated, either of trailing/leading edges of path changeover pulse is generated based on a path default generated by a control circuit 10. That is, the trailing/ leading edge of the path changeover pulse is selected by an edge selection means 20, an edge detection means 30 detects a trailing or a leading edge to generate a monitor pulse. Thus, the transmission line changeover state monitor pulse generating circuit is realized with a circuit of a small scale.

Abstract: PROBLEM TO BE SOLVED: To irradiate nearly uniformly light at a reading time by a solid image pickup element on a member to be read existing in a spatial area from a platen surface to a prescribed height position than this platen surface. SOLUTION: When a reflection angle of a reflection surface A5 of a reflector 213A is shifted to a right direction by a prescribed angle making the reflection angle left/right uniformly irradiating for an optical axis L a reference, the light is emitted to the same area as a platen glass 202 surface for the optical axis L on the surface of the prescribed height (H=h) from the platen glass 202. When the prescribed height H=h is made a read surface, since the light is emitted from an oblique direction to this solid body, the light becoming a proper irradiation area on the platen glass 202 surface is displaced to a left direction. This is returned to the optical axial L direction by changing the reflection angle of the partial reflection surface of the reflector 213A.

Abstract: PURPOSE:To reduce the number of light emitting and receiving elements and cost by arranging optical fibers connected to the light receiving elements for detecting projected beams on the side of a frame correspondingly to the optical axes of light emission side fibers. CONSTITUTION:When the light emitting elements 6a are emitted by a controller 8 and light beams are projected through the optical fibers, the optical fibers 1b, 1d, 1e, 1g are simultaneously emitted. When the light receiving elements 5a are also driven by the controller 8 correspondingly to the light emission, the optical fibers 1j, 1k, 1m, 1n start to receive the light beams. If a substance to be detected exists between the optical fibers 1j and 1b and between 1e and 1m, the input levels of the light receiving elements 5 are changed. When the light receiving and emitting elements 6, 5 are successively driven by the controller 8, the position 10 of the substance to be detected can be detected by a deciding circuit 11. Consequently, the number of light emitting and receiving elements can be reduced and the cost can be reduced.
