    Abstract: PURPOSE:To enhance X-ray detection efficiency by arbitrarily setting a pressure of operating gas of an X-ray detector by means of a regulating mechanism. CONSTITUTION:Operating gas incorporating, in a predetermined ratio, respective gas components from a plurality of gas bombs 22 with pressure reducing valves by means of a gas mixer 21 is introduced in an X-ray detector 2 via a pipe 31, to be exhausted through another pipe 32 by means of a rotary pump 20. A pressure of the operating gas is controlled by a pressure regulator 18 comprising a vacuum gauge, a variable leak valve and a controller. The pressure regulator 18 PID(proportional plus integral plus derivative)-controls the opening/closing of the variable leak valve of the pressure regulator 18 in accordance with a difference between a set pressure value and a measured pressure, to regulate conductance with respect to the operating gas, to thus supply the operating gas into an X-ray detector 2 while keeping it at a predetermined gas pressure. Therefore, setting of the pressure of the operating gas enables measuring accuracy of the X-ray detector 2 to be enhanced.

    Abstract: PURPOSE: To use in an environment to which high mechanical shock and vibration are applied by locking a screw type adjusting means of wire tension in a position capable of setting the fundamental vibration frequency of a wire at a high value different from a specific frequency of vibration environment. CONSTITUTION: A wire 1 is welded to first fixing parts 11, 21, and the wire 1 is stretched by rotating a nut 23 bonded to a locking part 24. The fundamental vibration frequency of the stretched wire increases with increase in tension, and the frequency is adjusted in a value higher than frequency usually generating in environment in which the frequency is monitored during adjusting the nut 23 and a counter is used, or in a value which is not usually generated in its environment. Thereby, the desired high tension of the wire 1 is obtained. A vibration and temperature test program is applied to the stretched wire 1 in a tube, screw adjusting means 22-24 are adjusted again, and the tension of the wire is adjusted until the desired fundamental vibration frequency is obtained. When the tension of the wire corresponding to the desired high fundamental frequency of 500Hz or higher for example is obtained, the adjusting means 22-24 are locked.
