摘要： This aims to provide a DOI type radiation detector in which scintillation crystals arranged two-dimensionally on a light receiving surface to form rectangular section groups in extending directions of the light receiving surface of a light receiving element are stacked up to make a three-dimensional arrangement and responses of the crystals that have detected radiation are made possible to identify at response positions on the light receiving surface, so that a three-dimensional radiation detection position can be obtained. In the DOI type radiation detector, scintillation crystals are right triangle poles extending upwards from the light receiving surface and the response positions on the light receiving surface are characterized. With this structure, DOI identification of a plurality of layers can be carried out by simply performing an Anger calculation of a light receiving element signal.

摘要： A telephone line-switching device comprises first and second switches that interlock and a lock plate extending between the two switches. The push member of the first switch has a cam with which the lock plate usually engages. The push member of the second switch has an inclined portion on which the lock plate always bears. As the push member of the second switch is depressed, the inclined portion horizontally moves the lock plate, permitting the lock plate to disengage from the cam to release the first switch.

摘要： Upon detection of radiation by using a (three-dimensional) detector capable of distinguishing a detection position in a depth direction and energy, an energy window for distinguishing between a signal and noise is changed depending on the detection position in the depth direction, thus making it possible to obtain scattering components inside the detector. Alternatively, a weight is given to a detection event depending on the detection position in the depth direction and energy information to obtain scattering components inside the detector. Thereby, scattering components inside the detector can be obtained to increase the sensitivity of the detector. In this case, different detecting elements can be used depending on the detection position in the depth direction.

摘要： In a DOI radiation detector, scintillation crystals are arranged in three dimensions on a light receiving surface of a light receiving element, and a response of a crystal having detected a radiation ray can be identified on the light receiving surface. Thereby, a position at which the radiation ray is detected is determined in three dimensions. In this DOI radiation detector, regular triangular prism scintillation crystals are used, and response positions of the respective crystals are shifted for each set. This allows crystal identification without loss even with a structure such as a three-layer or six-layer structure hard to achieve by a quadrangular prism scintillation crystal.
