Title: Apparatus and method for detection of two-dimensional radiation image
Inventor: KATAGIRI MASAKI
IPC: G01J1/02
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To obtain an apparatus and a method in which the pulse-height shape of a light emitting signal in a multichannel is changed easily into a time based shape and a digital signal by a method wherein, when a signal is detected by using an optical fiber so as to find a two-dimensional radiation image, a streak camera method is used. SOLUTION: An ionizing radiation is converted into light by a radiation detecting body in which a plastic scintillator is made sheetlike. An optical fiber bundle is arranged to be a face shape on the rear of the radiation detecting body in order to detect fluorescence. An optical system arranges beams of light radiated from both ends of the optical fiber bundle to be a transversely parallel shape, and the width of the beams of light corresponding to their transverse width can be made variable. A streak tube which is time-swept at high speed detects the output light of the optical system in a multichannel. An imaging camera images a streak image which is output to the streak tube. A signal processing analyzer digitizes its image signal so as to be stored as data in which the intensity of a light emitting signal is changed into a time-series shape.  It is analyzed and processed, and a two-dimensional radiation image is obtained.

Title: High efficiency type cooling tower and cooling method
Inventor: ICHIKAWA MASAHIDE
IPC: F28C1/00
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To improve the heat-exchange efficiency of cooling water by a method wherein setting of high voltage electric field or heat-exchange with a refrigerant, such as ice and dry ice, is carried out. SOLUTION: Promotion of cooling of cooling water is effected by setting of a high voltage electric field and heat-exchange with a refrigerant, such as ice and dry ice. The high voltage electric field is easily set in a way that an electrode 1 connected to a high voltage source is arranged in the vicinity of the surface of an object to be cooled and the object to be cooled indirectly or directly. In this case, it is predicted that the humidified air film of the part, making contact with cold air, of an object to be cooled is removed by electron emitted from an electrode 1 and the removed part is heat-exchanged with cold air. Further, it is decided that ice and dry ice are also properly used as a refrigerant used for heat-exchange in terms of a cost performance effect.  Further, the heat is stored in a refregerant by inexpensive midnight electric power and the electricity is discharged during daytime when a refregerator is highly loaded.
