    摘要: A method and apparatus for superimposing a plurality of electron beams at a desired location after X-ray tube manufacturing processes are generally complete. The method is embodied in providing mechanical and electrical means which are internal to the X-ray tube which provide means for adjustment of a focal point of a plurality of electron beams being emitted from a cathode assembly to thereby provide precise control of where the plurality of electron beams achieve superimposition on a target anode.

    摘要: A method and apparatus for reducing off-focus radiation by modifying a shape of a rotating target anode disposed within a cathode grounded x-ray tube. The shape of the target anode body is modified such that surfaces of the target anode which could otherwise direct the greatest amounts of off-focus radiation toward an x-ray sensitive imaging device are angled or shortened so as to redirect the off-focus radiation away from a focal direction. These modifications to surfaces of the target anode body include modifying a front surface, a side or edge surface, and a back surface.

    摘要: Calender and process for operating calender depending upon a desired surface quality, in which calender includes a plurality of nips located between end nips formed by replaceable rolls and end rolls. Process includes selectively guiding a web though several nips of calender and at least one end nip of calender, and when the web is selectively guided through the at least one end nip, selectively replacing the replaceable roll with one of a hard and a soft roll to form the at least one end nip with a hard roll and a soft roll or with two soft rolls. The replaceable roll being connectable to a temperature control device operated with a tempering capacity that depends on the type of the replaced roll.

    摘要: A method and apparatus for providing a window frame and window for use in an x-ray tube, wherein the new structure reduces deforming stresses on the window produced by pressure differential incident upon the window. The support structure of the window frame to which the window is attached is angled toward the interior of the x-ray tube to an angle equaling the deflection to which a window is typically subjected in standard window frames. A window mounted to a frame in accordance with the present invention is subjected to reduced or eliminated deforming stresses, even in high deflection stress environments including air bake x-ray tube manufacturing processes. This elimination of deforming stresses allows for the use of thinner x-ray tube windows enabling a higher transmissivity of produced x-rays.

    摘要: A control knob controls jog/shuttle operations on an audio/video payback/record device. The knob is formed of a cylindrical body having an outer portion and a face portion that has convex and concave regions, respectively, integral with each other. The convex region lies centered within, and surrounded by the concave region and with the two regions joined with a smooth radius transition. The smooth radius transition creates a topology that allows manipulation of the knob with only a small frictional force by a single finger of a user (not shown), thus allowing precisely rotation of knob to enter a jog mode at any angular position of the finger.
