Title: Optical disk
Inventor: UENO ICHIRO
IPC: G11B7/24
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To make it possible to reproduce recorded information with reproducing light power which optimizes a mask effect without the destruction of the information. SOLUTION: The optical disk is formed by laminating a recording layer 6 which records and reproduces the information and a mask layer 4 which increases light transmittance when the intensity of light for irradiation increases. The optical disk is so constituted that the diameter of the light spot transmitted through the mask layer 4 is substantially smaller than the diameter of the light spot made incident on the mask layer 4. In such a case, a light attenuation layer 12 for attenuating transmitted light is formed between the recording layer 6 and the mask layer 4. As a result, the recorded information is reproduced with the reproducing light power which optimizes the mask effect.

Title: X-ray inspecting apparatus
Inventor: NISHIDE AKIHIKO
IPC: G03B42/02
Filed: 1991-04-11
Abstract: PURPOSE:To obtain an X-ray inspecting apparatus wherein a transmitted X-ray image and scattering X-ray images are overlapped and displayed so that the perspective solid structure of a body to be inspected is readily understood. CONSTITUTION:When a body to be inspected 1 is being conveyed with a belt conveyer 2, pencil-beam X rays perform raster scanning on the right and left side surfaces of the body to be inspected. Thus, a scattering X-ray image on the left side surface, a transmitted X-ray image and a scattering X-ray image on the right side surface are obtained. Then, these images are synthesized on an image display. At this time, the moving speeds are made slower in the sequence of the scattering X-ray image on the left side surface, the transmitted X-ray image and the scattering X-ray image on the right side surface when the moving images are displayed. The more the X-ray images are located at the rear side, the more the moving speed is made slower in comparison with the scattering X-ray image on the right side, which is the image at the front side. Thus, the stereoscopic sense is imparted to the synthesized image of the body to be inspected.

Title: Master relay system in loop transmission line
Inventor: FUJII MASATO
IPC: H04L12/42
Filed: 1989-03-30
Abstract: PURPOSE:To simplify the hardware for taking synchronization and to easily attain synchronization when a remote station makes transmission by allowing a master station to always send any data to a transmission line. CONSTITUTION:In order to simplify the clock synchronization of a data to be sent, a master station always send any data to a transmission line. That is, when a remote station makes transmission (in this case, remote station R2), a master station M sends a clock signal. When the remote station R2 is going to send its own station data, the data has only to be sent synchronously with the received clock. Thus, the clock synchronization of the transmission data is facilitated and the required hardware is simplified.
