    摘要: This invention relates to a root canal treatment instrument comprising: a needle extending in a rodlike form, comprising: working section made of a superelastic alloy extending from a distal end of the needle; and a shank extending axially between the working section and a proximal end of the needle, made of at least partially a non-superelastic alloy, and a handle attached to a proximal end of the needle and adapted to be manipulated by a hand of a dentist. The working section possesses flexible nature because of its superelastic alloy composition, whereas the shank possesses rigid nature because of its non-superelastic alloy composition.

    摘要: The present invention provides a computed tomography system that only requires rotational scans for image pickup, the system enabling images of a plurality of testing objects to be simultaneously picked up without increasing the volume of noise or the scale of the system, thus enabling high-quality tomographic images to be efficiently picked up. In the computed tomography system, a plurality of turn tables 11a to 11d are provided in a region of irradiation with X-ray beams emitted by an X-ray irradiation system. Testing objects Ma to Md are placed on the respective turn tables. Images of the plurality of testing objects can be simultaneously picked up by irradiation with X-ray beams. This enables precise image pickup to be efficiently achieved without increasing the size of the scale.

    摘要: An X-ray sensor signal processing circuit and method used in an industrial X-ray CT apparatus for processing an output signal of a semiconductor X-ray sensor which detects a pulsed X-ray emitted from an accelerator and passed through an object to be inspected. The circuit includes a first resistor having one terminal connected to the X-ray sensor and an other terminal connected to ground, a first capacitor having one end terminal connected to a connection point of the X-ray sensor and the first resistor, an operational amplifier having an inverting input connected to an other terminal of the first capacitor, and an integrator having a second resistor and a second capacitor each connected to the operational amplifier in parallel. The circuit is configured so that at least bias conditions of the X-ray sensor and the first capacitor are returned to a steady state after irradiation of the pulsed X-ray.
