IPC: H05G1/34
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To facilitate the operation, while preventing erroneous operations by providing a foot switch for generating an output corresponding to an operated variable and a controller for changing the X-ray lamp current range in response to the output. SOLUTION: Multiple contacts of a foot switch 34 are turned on in order in response to the operated variable. When the foot switch 34 is operated relatively light, a first stage contact is turned on, and when the output of the foot switch 34 at this stage is input to a controller 31, the controller 31 selects the minimum lamp current range, and performs automatic luminance adjustment so that radioscopic lamp voltage FkV and radioscopic lamp current FmA are changed. In the case of a lack of luminance of the output image signal, FkV and FkA are increased by a feedback control system, and the predetermined luminance can be thereby obtained. The foot switch 34 is operated in response to a part of a person to be examined so as to the change the control characteristic.

Title: Liquid crystal display device
Inventor: ANABUKI MOMOKO
IPC: G02B6/00
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To make the luminance uniform by gradually decreasing the vertical angles of projection streaks formed on the surface of a prism sheet, interposed between a back light unit and a liquid crystal display panel, which faces the liquid crystal panel, as going far from the light source. SOLUTION: The prismatic projection streaks 4A, formed on the surface of the prism sheet 4 which faces the liquid crystal display panel (opposite surface from the surface facing the back light unit 5) gradually decrease in vertical angle from an angle θ1 to an angle θ2 as the distance from a cold cathode-ray tube 5B is larger. Light which is projected from the light guide plate 5A of the back light unit 5 at an angle to the perpendicular to the light guide plate 5A is refracted by a corresponding projection 4A on the prism sheet 4 and projected along the perpendicular. Consequently, the light can be transmitted through the liquid crystal display panel in the perpendicular direction over the entire area and the luminance of the light can be made uniform.

IPC: G11B20/12
Filed: 1990-11-14
Abstract: PURPOSE:To prevent the simultaneous disappearance of the same backup data together with their original data by a defect by recording the backup data at a position separated from the recording position of the original data on a magneto-optical disk by a prescribed rotation angle. CONSTITUTION:Backup data D are recorded at a position separated from the recording position of their original data by a rotation angle of about 180 deg.. At the time of recording the backup data, a recordable vacant track with a sector number of S0+8 or S0+9, meaning that the '8' or '9' is added to the sector number S0 of the recording position of the original data D, is found. The backup data D are recorded at the recording position of the vacant sector, the track number of which is the farthest from the track number T0 of the recording position of the original data D. Therefore, even when a defect occurs for some reason in the physical property of a magneto-optical disk, such as a change in composition, etc., the backup data do not disappear at the same time together with their original data.
