Title: Cathode-ray tube
Inventor: MATSUKIYO HIDEJI
IPC: H01J31/10
Filed: 1989-11-27
Abstract: PURPOSE:To improve the emission characteristic of a cathode-ray tube at the application of an electron beam of high density to the fluorescent screen of the tube and heighten the brightness and brightness-life characteristic of the tube by cooling the fluorescent screen of the tube under specific conditions. CONSTITUTION:Temperatures below room temperature can be readily achieved through the absorption of heat by passing currents through dissimilar conductors or semiconductors i.e., the so-called Peltier effect. While a cathode-ray tube is open at room temperature and put in its steady state by actuation of the tube through excitation of high density i.e., a current density of more than 0.1mA/cm<2> per irradiation area and at an accelerating voltage of more than 25kV, the tube is forcibly cooled so that the temperature of the tube surface is more than room temperature and less than 60 deg.C. A cooling effect against the emission characteristic of the cathode-ray tube is thereby heightened so as to heighten the brightness and brightness-life characteristic of the tube.

IPC: A61B6/06
Filed: 1990-11-09
Abstract: PURPOSE:To enable generation of an image data carrying information on an image of high picture quality without noticeable noises attributed to a grid used in photographing by arranging radiation shielding matters at irregularly varying intervals. CONSTITUTION:Radiation 2 radiated from a radiation source 1 is applied to a storage phosphor sheet 11 via an object 3 and further via a grid 4. The grind lead 4a and aluminum 4b arranged alternately at intervals varied irregularly centering around four lines/mm. The radiation 2 is interrupted by the lead 4a and is applied to the sheet 11 being transmitted through the aluminum 4b. As a result, stripe patterns of irregular intervals centering around four lines/mm are recorded in the sheet 11 together with a radiation image of the object 3. This enables the prevention of aliasing noises from concentrating on a specified spatial frequency even when a radiation image taken and recorded using the grid 4 is read out at fixed sampling intervals thereby generating an image data carrying information on an image of high picture quality with aliasing noises lowered at least apparently.
