Renting for $2,850 a month, the IBM 740 also was used with the IBM 704 and IBM 709 Data Processing Systems. The recording unit had a persistence of several microseconds and the display unit had a persistence of approximately 20 seconds.
#Cathode ray tube full
(0.1 percent means that if a point with the same coordinates were to be displayed twice, the successive spots would differ in position by not more than 0.1 percent of full scale.) The time consumed in displaying a particular point was approximately 125 microseconds. The recording unit had an accuracy of 0.1 percent and the display unit had a 3.0 percent accuracy. Traffic schedules or machine shop loadings, for example, could be shown on the 740, giving the operator the opportunity to monitor and incorporate data to facilitate the solution. By using appropriate programming techniques, the 740 also could be used to display alphabetic characters, geometric shapes, engineering symbols and graphs. For example, the shape of a cam could be computed and the shape, together with successive positions of the cam, could be displayed on the 740 at electronic speeds, inspected and then photographed for a permanent record. The direction of deflection can be determined by using Fleming’s Left-hand Rule.

Cathode ray can be deflected by the magnetic field. However, instead of impacting the anode and returning to the. When enough of the air in the chamber has been removed, electrons will freely accelerate from the negative electrode (cathode) towards the positive electrode (anode). Cathode ray can be deflected by the electric field. Essentially, our cathode ray tube is just two electrodes in a vacuum chamber with a high voltage applied between them. The CRT modulates, accelerates, and deflects electron beam (s) onto the screen to create the images. It contains an electron gun, and this gun shoots electrons toward the phosphorescent screen. It is used to display images on a screen. Cathode ray can produce a fluorescent effect. The cathode-ray tube (CRT) is a vacuum tube. The device provided scientists and engineers with greater speed and accuracy in designing many types of equipment. Both the experiment of Maltese Cross Tube and the Deflection Tube show that. Huge collection, amazing choice, 100+ million high quality, affordable RF and RM images. These accelerated electrons collide into the gas inside the tube, thereby allowing it to glow. The 740 allowed decision making and possible intervention by the operator as the computation progressed. Find the perfect cathode ray tube stock photo. The cathode ray tube (CRT) is a vacuum tube, in which electrons are discharged from the cathode and accelerated through a voltage, and thereby gains acceleration of some 600 km/s for every volt. A customer-furnished camera was controlled by the 701 and automatically photographed information directed by the program. (General Physics) a valve in which a beam of high-energy electrons is focused onto a fluorescent screen to give a visible spot of light. The smaller tube, used in conjunction with a camera, was a 7-inch tube. The larger tube, used for visual display and inspection, was a 21-inch tube. It provided output which recorded data points on the faces of a pair of television-like tubes at the rate of 8,000 per second. \( \newcommand\): The cathode ray tube was first invented by Sir William Crookes.Formally announced on October 12, 1954, the 740 CRT output recorder was an electronic device attached to the IBM 701 Data Processing System.
