An x-ray tube, in addition to an anode and a cathode arrangement, has first and second electrodes that are located in an evacuated housing provided with a beam exit window. The anode and the first electrode are at potentials that are positive in comparison to the potentials of the cathode arrangement and the second electrode. Further, the first and the second electrode are arranged lying opposite one another such that secondary electrons emanating from the anode must pass through the space located between the first and the second electrode in order to proceed to the beam exit window. These secondary electrons are thus substantially all prevented from reaching the beam exit window, thereby avoiding excessive heating of the beam exit window.

A planetary gear extruder for the compounding and extrusion of thermoplastic materials, in which an annular groove is formed in the metallic stop ring to receive a ceramic body which is engageable by the forward ends of the planetary spindles in order to reduce friction. A ceramic body may additionally also be arranged in a recess in the end face of each of the planetary spindles, aligned with and adapted to engage the ceramic body mounted in the stop ring. As a result, the coefficients of friction between the stop ring and the end faces of the spindles are reduced considerably, consequently reducing the wear on the planetary spindles themselves and the central spindle.
摘要:
A method for applying a transparent, conductive indium-tin oxide coating on a substrate of amorphous, hydrogen-containing silicon wherein an unheated substrate of amorphous hydrogen-containing silicon is treated with sources of indium and tin in a first stage while maintaining a low partial pressure of oxygen until a partial coating is built-up, then reducing the oxygen partial pressure in the coating zone in a second stage and continuing the coating until an additional coating thickness is built-up, followed by heating the coated substrate in an oxygen-containing atmosphere at a temperature less than 250.degree. C.

A circuit for unilaterally scanning teletype characters wherein the characters are supplied to an integrating circuit and to an impulse circuit wherein the impulse circuit can be controlled by the step changes of a character. A comparator circuit receives the output of the integration circuit and assumes a definite condition with each step change through a switch which is controlled by the impulses of the impulse circuit and a reference signal is supplied to the comparator circuit and the reference signal can be adjusted according to the desired delay of the descending or ascending edge of the step changes in the characters.

The invention relates to a method for remote-control programming and to a machine control system 2 for performing the method. To refine the method so as to simplify and shorten an execution operation of a control program source yet automatically avoid version conflicts between the control program source and the compilate in the machine control system, it is proposed that the program source 3a stored in memory in the machine control system be executed by means of a programming device 1, and after the execution, the compilate of the executed program source is generated and stored in memory in the machine control system, where it is made available to a control module.
