Filed: 1990-03-28
Abstract: PURPOSE:To reduce warpage of disk plates during use by giving warpage to the optical disk at normal temp., and normal pressure so that the warpage of the disk decreases under conditions of low temp. and high pressure or high temp. and low pressure. CONSTITUTION:The optical disk 1 is formed to have warpage at normal temp., and normal pressure so that the warpage of the disk decreases under conditions of low temp. and high pressure or high temp. and low pressure. As for the optical information recording medium of air-sandwitch sealed structure to be used under low temp. and high pressure, the disk plates are preliminarily bent outwardly in the process of assembling the medium at normal temp. and normal pressure. On the other hand, if the medium is to be used under high temp. and low pressure, the disk plates are bent inwardly. Thereby, warpage of the plates 2 can be reduced during use.

Title: Fluoroscopic photographing device
Inventor: KASHIMA NOBUYOSHI
IPC: H05G1/34
Filed: 1990-03-29
Abstract: PURPOSE:To shorten the time required for completing heating of a filament for large focus and shorten the time for snapshot by applying as a heating voltage for a filament for large focus a voltage larger than that corresponding to the current of a photographing tube at first, and changing the voltage to one corresponding to the set current of the photographing tube from the point at which heating is completed, so as to output an X-ray. CONSTITUTION:When a fluoroscopic photographing device is started for snapshot photography, focus is changed from small to large. At the same time a CPU 5b controls a filament heating circuit 5a so that the service maximum voltage (maximal heating level voltage) of a filament for large focus is applied from a filament heating transformer 3 to an X ray tube 1. When the temperature of the filament is raised to a fixed temperature corresponding to the current of a photographing tube, i.e., heating of the filament is completed, this is detected by a filament heating circuit 5a by that the current of the filament becomes a fixed value corresponding to the current of the photographing tube. When this is detected, the CPU 5b performs switching control of the voltage of the filament heating circuit 5a so that voltage (heating level voltage for photography) corresponding to a photographing current is applied from the filament heating transformer 3 to the X-ray tube 1 ; the CPU is then operated to output an X-ray.
