    摘要: An X-ray CT apparatus, wherein a drum type rotation frame is rotatably supported by a fixed circular frame so as to surround an outer surface of the drum type rotation frame through a plurality of bearings provided between an inner surface of the fixing circular frame and an outer surface of the drum type rotation frame, for example in ring-like configuration. When the drum type rotation frame receives a large centrifugal acceleration due to a high speed rotation, outside expansion of the drum type rotation frame can be constrained due to both the rigidity of the fixed frame and the rigidity of the plurality of bearings provided on the outer surface of the rotation frame, thereby to maintain the relative positions of the X-ray tube and the X-ray detector and prevent deterioration of reconstructed images.

    摘要: An ultrasonic flow rate measurement device includes a measurement channel, through which a fluid to be measured flows; and a sensor fixing casing having openings formed in the measurement channel and sensor fixing cavities communicating with the openings. Moreover, the ultrasonic flow rate measurement device includes a pair of ultrasonic sensors contained in the sensor fixing cavities, for measuring the flow rate of the fluid to be measured; and a flow rate measuring unit for detecting the flow rate based on an ultrasonic wave propagation time between the pair of ultrasonic sensors. Furthermore, the ultrasonic flow rate measurement device includes a suppressing member formed at each of the openings, for suppressing the fluid to be measured from intruding into each of the sensor fixing cavities, wherein the suppressing member is molded integrally with the sensor fixing casing.

    摘要: Provided are an acoustic matching member with a fixed density, an ultrasonic transmitter/receiver unit with a high sensitivity, and an ultrasonic flow meter device which attains stable and high-accurate flow measurement. An acoustic matching member comprises hollow elements and a binding agent. The acoustic matching member is created by removing hollow elements having higher densities, hollow elements having cracks, etc., from hollow elements before sorting-out. Since the hollow elements having higher densities, the hollow elements having cracks, etc., are removed from hollow elements before sorting-out, it becomes possible to provide an acoustic matching member having fixed characteristics without being affected by a manufacturing lot and a transportation process of the hollow elements. An ultrasonic transmitter/receiver unit created using the acoustic matching member has fixed characteristics and is able to perform high-accurate flow measurement.
