    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.

    摘要: A discharge tube structure of a gas laser generator has end common vessels at its both end sections and an intermediate common vessel at its intermediate section. The end common vessels and intermediate common vessel are connected through the first and second cooling ducts to a centrifugal blower, which is provided at its center the first communicating port communicating with the first cooling duct and at least two second communicating ports communicating with the second cooling ducts opposed to each other with respect to the first communicating port. The simplified second cooling ducts allows the mixture gas to be supplied smoothly to the intermediate common vessel, thereby increasing the laser output.
