    摘要: A positron CT scanner includes a plurality of detectors arranged in a generally cylindrical multi-layers of rings, and slice septa for restricting visual fields of the detectors so that the visual fields intersect a set axis. An interval of the slice septa is substantially corresponds to a plural number of detector cells each of which can determine positions of .gamma. rays incident in the direction of the set axis. The slice septa are movable relatively to the detector cells in the direction of the set axis during a .gamma. ray counting operation.

    摘要: An image processing apparatus includes a first path information calculating unit, a second path information calculating unit, and a path selecting unit. The first path information calculating unit calculates first path information which is information representing a first path for separating areas from an image. The second path information calculating unit calculates second path information representing a second path for separating the areas from the image, the second path being the reverse of the first path. The path selecting unit selects one of the first path information calculated by the first path information calculating unit and the second path information calculated by the second path information calculating unit.

    摘要: A radiation detector basically comprises a scintillator, a light guide for introducing scintillation light, and a photodetector for detecting the scintillation light. A light output portion of the scintillator is wedge-shaped, and a light input portion of the light guide is V-shaped in section so as to receive the wedge-shaped light output portion of the scintillator. With this arrangement, light reflection at the interfaces of the scintillator and light guide is reduced, resulting in an improvement of transmission efficiency of light.

    摘要: There is provided a combustion appliance with a safety device. An oxygen partial pressure sensor made up of a transition metal oxide or rare earth metal oxide is normally disposed in a position in which the excess air ratio downstream of a flame formed by a burner can be detected and, at times of abnormality, within the flame. The resistance change of said oxygen partial pressure is detected and the combustion is stopped when incomplete combustion occurs due to oxygen depression, clogging of the primary air orifice of the burner or clogging of the combustion chamber with the products of combustion.
