Title: Preventing method for burning of linear motor coil
Inventor: YAMAMOTO HIROSHI
IPC: H02P25/06
Filed: 1988-01-29
Abstract: PURPOSE:To prevent the burning of a linear motor coil by having the output of a command for shift distance of small numerical value in case the shift of the coil is impossible up to a target position due to an external factor and obtaining a positioning end signal to eliminate the overload of the linear motor. CONSTITUTION:In case no positioning end signal is received within a fixed time after the output of a digital shift distance command received from a control microcomputer 2 in the first step, an operator call signal is produced in the next step and an error message is displayed on a screen. Then a digital shift distance command of small numerical value is outputted in the direction opposite to that of the digital shift distance command received from the microcomputer 2. In this case, the former command signal is continuously outputted until the positioning end signal is given to the microcomputer 2 from a window comparator 9. As a result, no overload is applied to a linear motor and therefore no energizing current flows continuously to a coil for a long period of time.

Abstract: PURPOSE:To increase the freedom degrees of the shapes of electrodes and the positions of getter attachments by storing a zircon getter in a case also serving as a return-electron-beam limiting plate, and fixing said zircon getter to an electrode located between an accelerating electrode and a target. CONSTITUTION:A zircon getter 6a is fixed by welding a boat 11 to a bottom aperture 8a also serving as a return-electron-beam limiting plate. Since the getter 6a is stored in a case consisting of the bottom aperture 8a and washers, even if the getter 6a becomes brittle by adsorbing gas on it, there is no possibility that the getter 6a sticks to a network or the like after turning into dust and that a black stain in caused on the screen of the pickup tube. The area of the flat- plate-like second grid 13 to which a getter is fixed is selected so that the bottom aperture 8a can properly limits return electron beams. By the means mentioned above, since the zircon getter 6a can be fixed to other positions as well as to the second grid (accelerating electrode) 13, the freedom degrees of the shapes of electrodes and the positions of getter attachments are increased.
