    摘要: With respect to two or more NC data points among a group of dots together representing a tool locus, a curvature radius of the tool locus is determined. Then, the NC data point and its succession with other points is displayed in a display color determined according to the magnitude of the curvature radius. Alternatively, a movement direction of each minute segment relative to a specific axis selected from the three (XYZ) axes is determined as either positive, negative, or zero, and the minute segment or an end point thereof is display with the display property determined according to the movement direction. Still alternatively, after a specific axis is selected from the three (XYZ) axes, a region relative to the selected region is divided along the selected axis, for predetermined dividing width, first beginning with a predetermined reference point, and the resultant divided regions are given predetermined display properties. Then, a tool locus is displayed in the three-axial (XYZ) system according to the display properties given to the respective divided regions.

    摘要: The present invention relates to an X-ray tube with a structure, by which the charging of an insulating member, disposed inside a container, is effectively prevented to enable stable operation to be secured. This X-ray tube has an electron source that emits electrons, a target that generates X-rays in response to the incidence of the electrons, first and second electrons, each having a side face portion that extends along the direction of incidence of the electrons and forming a predetermined electric field between the electron source and the target, and an insulating support member, for supporting the first and second electrodes, being disposed along the side face portions of the first and second electrodes. The second electrode, of the first and second electrodes, is positioned closest to the target and has an anti-charging edge portion that is positioned at an X-ray generating surface end of the side face portion and that extends toward the exterior of the container so as to cover over the support members from the target.

    摘要: An amplifier circuit having a differential amplifier, provided in a semiconductor integrated circuit is disclosed. The differential amplifier has one input connected to a reference voltage generating circuit. The voltage outputted from the reference voltage generating circuit includes a voltage fluctuation depending on the fluctuation in power-supply voltage Vcc. However, a fluctuation absorbing circuit comprising resistors 51 and 52, diodes 53 and 54, and a capacitor 55 absorbs the voltage fluctuation thereof. As a result, the change in offset voltage of the differential amplifier is prevented, resulting in an improvement of a power-supply rejection ratio.
