Title: Cassette for x-ray tomographic imaging and x-ray simultaneous multilayer tomographic imaging method using the same cassette
Inventor: UEMATSU SADAO
IPC: A61B6/02
Filed: 1989-02-15
Abstract: PURPOSE:To make processing possible in a bright chamber by constituting both surfaces of a plurality of superposed cassettes of an X-ray highly permeable material and making simultaneous multilayer imaging possible by one irradiation with X-rays and subjecting an accumulative fluorescent plate to image processing electrically after the exposure to X-rays to analyze the same. CONSTITUTION:An X-ray tomographic imaging cassette 10 is provided in an almost paper clip state wherein a surface lid 1 positioned on the side of a patient with respect to an X-ray irradiation direction and a back lid 2 positioned on the opposite side are connected by a pair of hinges 3. Then, the cassette 10 is brought to an open state to mount an imaging plate (IP plate) 30 composed of an accumulative fluorescent plate. The IP plate 30 can accumulate the X-ray data of the patient irradiated with X-rays and, on the basis of the light emitted from the IP plate 30, for example, a film is exposed to light to form an image. Both of the surface and back lids 1, 2 are formed from an X-ray permeable material having light shielding properties, especially, from a carbon plate having high X-ray permeability. A plurality of the cassettes are received in an X-ray impermeable receiving box in a superposed state and the exposure dose of the patient at one irradiation with X-rays is reduced to perform simultaneous multilayer tomographic imaging. Further, by performing automatic processing using the IP plate, the processing in a bright chamber is made possible and imaging can be simplified.

Filed: 1984-02-24
Abstract: PURPOSE:To prevent crosstalks among wireless microphones by setting automatically the reception channel of both a receiver and the transmission channel of the wireless microphone to the idle channel of the receiver when a wireless microphone is set at a prescribed position of the receiver. CONSTITUTION:When a wireless microphone 100 is set to a hollow part 202 of a receiver 200, connectors 144 and 244 are connected to each other. At the same time, switches 143 and 243 are changed to OFF from ON and to ON from OFF respectively. This discontinues the transmission of the microphone 100 and at the same time the value N is supplied to a dividing circuit 222 from a microcomputer 230. Thus the reception channels are changed consecutively. At the same time, ''O'' and ''L'' of the detection output Sd of a detection circuit 242 are checked by the computer 230. Thus an idle channel is searched. An idle channel is decided when Sd=1 is satisfied. Thus the value N of the circuit 222 is fixed to the value Ni and at the same time the value Ni is loaded in parallel to a latch 131 from the computer 230 through connectors 244 and 144.

Abstract: PURPOSE: To maintain constant the elution time of cystine and reduce frequency of eluate adjustment, by supplying the eluate of the second stage into the separation column before cystine is eluted from the separation column by the eluate of the first stage.  
     CONSTITUTION: In an amino acid analytical method to separate into components the amino acid mixture speciment introduced into a separation column 7 by successively supplying plural eluates differing in pH into the separation column 7, the value of pH of eluate B 1  on the first stage is kept at a low value to permit only an insufficient separation of cystine and valine, while the value of pH of eluate B 2  on the second stage is maintained at a higher value than that of the first stage eluate B 1  so as to permit sufficient separation of cystine and valine. Thus, cystine, soon after changing over to the second eluate B 2 , is eluted, so that the elution time may be constant as far as the changing-over time be constant. Besides, since the peak of cystine is sharp, the detecting sensitivity may be higher.
