摘要: An industrial X-ray tube formed by accommodating a cathode and anode in a container having an evacuated interior, in which electrons emitted from the cathode are caused to strike the anode and X-rays are emitted from the anode. The cathode is formed from graphite. The graphite is a layered crystal obtained by layering a plurality of carbon hexagonal planes. The graphite is cut based on crystal axes of the carbon hexagonal planes. The resulting cut surface is caused to function as an electron-emitting surface. For example, directions of an a- and b-crystal axis may be set so as to be arbitrary between each of the layers of the carbon hexagonal planes, the graphite may be cut along a surface parallel to the c-axis, and the resulting cut surface may be caused to function as an electron-emitting surface. The graphite may also be cut along a surface orthogonal to the c-axis.

摘要: A motion control system comprising a servo motor for moving a rotary stage; a scale provided on the rotary stage or on an object that moves integrally with the rotary stage; a plurality of reading heads for detecting the scale and outputting a signal; a data processing part for calculating an average value of rotation angle data based on each of the output signals from the reading heads and outputting the average value as a signal; and a servo amplifier for controlling the motor based on the signal representing the average value of the rotation angle. The motion control system can cause the rotary stage to rotate to a desired rotation angle to a high degree of accuracy using the reading heads.
