摘要： An X-ray detector of an X-ray CT apparatus has a collimator, a plurality of scintillators, a light reflector and a plurality of photodiodes. The collimator has a threshold plate with a thickness Wc to eliminate scattered radiation from an X-ray. The plurality of scintillators emit light based on the X-ray. The light reflector is provided in a gap between adjacent scintillators of the plurality of scintillators. The plurality of photodiodes convert the light of each of the plurality of scintillators into the electric signal. The thickness Wc of the threshold plate mounted on the X-ray incident side of the adjacent scintillators, and a thickness Ws of the gap has a relationship shown in a following expression: Wc≧Ws.

摘要： According to one embodiment, detector and DAS includes an X-ray detector, a board, a DAS, and a plurality of X-ray shielding plates. The X-ray detector detects X-rays and generates an electrical signal corresponding to the detected X-rays. The board is coupled to the X-ray detector and includes a wiring pattern to extract the electrical signal from the X-ray detector. The DAS is coupled to the board and included an electronic part to perform signal processing for the electrical signal. The X-ray shielding plates are provided for the board to prevent the electronic part from being exposed to X-rays transmitted through the X-ray detector. A portion of the wiring pattern is placed between the X-ray shielding plates.

摘要： A displacement-measuring apparatus including a cylindrical housing, a static-pressure bearing located within the housing, a probe shaft supported by the bearing so that the bearing is supported in non-contact fashion and is movable in the axial direction, and a stylus connected to the end of the probe shaft so as to apply pressure to an object. Part of the static-pressure bearing includes a hollow cylindrical bush and at least two restriction holes formed in the bush and equidistantly spaced along the circumference of the bush. These holes supply air into the gap between the probe shaft and the bush. The static-pressure bearing further includes a first set of grooves formed in the inner surface of the bush that extend along the axis of the bush so that each opposes at least one restriction hole, and a second set of grooves formed in the circumferential surface of the probe shaft that extend along the axis of the probe shaft. The second set of grooves are arranged in pairs with each pair being made of two grooves that are symmetrical with respect to the corresponding groove of the first set.
