IPC: G01T1/164
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To gather data in a short time by the scintillation camera of a positron tomographic device and to greatly improve the detection sensitivity. SOLUTION: This camera is equipped with a calculating circuit 14 which assumes that radiation is generated is generated on one or more planes positioned between two detector parts 2a and 2b among detector parts and finds the intersections of the line connecting the positions where the radiation is made incident on the two detector parts 2a and 2b and the one or more planes to calculate the generation position of the radiation. Consequently, the detector parts 2a and 2b need not be rotated around a body 1 to be detected and data can be gathered in a short time. Further, radiation (obliquely incident radiation) other than the radiation which is made incident vertically on the radiation incidence surface of each detection part can be used for imaging, so the detection sensitivity can be improved greatly as compared with a case wherein only the vertically incident radiation is used.

Title: Noninductive magnetic shield type bushing using high temperature superconducting material
Inventor: INUKAI EIKICHI
IPC: H01B17/58
Filed: 1990-10-29
Abstract: PURPOSE:To maintain the cooling effect for a long period of time by enclosing a noninductive type conducting body of high temperature superconducting material with a magnetically shielding body, and providing a bushing, cooled by liquid nitrogen, in a housing vessel for superconductivity cooled by liquid helium. CONSTITUTION:A current flows through an outer member 9A and a superconductivity application apparatus 1 to a center member 9B when a direct current voltage is applied across rod-like terminals 13, 14. Thus, sufficient current feeding can be done, since the fluxes generated by the members cancel each other and a magnetic shielding body 8 hinders the penetration of a flux from the outside. And, the dissipation of cold from the liquid helium 3 decreases, since an electrically conducting body 9 and the shielding body 7 are cooled by liquid nitrogen 18 so that the liquid nitrogen 18 intervenes between liquid helium 3 and the atmosphere, and further since the conducting body 9 and the shielding body 7 are formed by a high temperature superconducting material which has low thermal conductivity. Thus, a required current can be fed in a superconductivity application apparatus, as well as the cooling effect can be maintained for a longer period.

Abstract: PURPOSE:To always attain a light transmission whose precision is high without being affected by a temperature or a secular change by calculating the light transmitting efficiency of a transmission line, and correcting the peak value of a signal based on the calculated light transmitting efficiency. CONSTITUTION:A detector generates a charge in proportion to the energy of an incident radiation. An oscillator 11 outputs the sine wave signal of a lower frequency than a pulse signal generated by an amplifier 2. An output signal from an adder 12 is converted into an optical signal by an electrical-to-optical transducer 3, transmitted through an optical cable, and converted into an electric signal again by an optical-to-electrical transducer 5. The electric signal is separated into the pulse signal and the sine wave signal by a high pass filter 13 and a low pass filter 14. Those signals are stored through A/D converters 71 and 72 of a data processor 6 in a memory 8. A CPU 9 calculates the light transmitting efficiency of the light transmission line based on the change of the amplitude of the sine wave signal in the memory 8, and corrects the peak value of the pulse signal based on the calculated light transmitting efficiency.
