Title: Electric field radiation scanning electron microscope
Inventor: NAKAIZUMI YASUSHI
IPC: H01J37/073
Filed: 1978-07-17
Abstract: PURPOSE:To assure photography and prevent the electron source from melting and deteriorating by stopping the operation of protective means of electron rays during recording scanned results of samples by electron rays. CONSTITUTION:A switch 6 is closed when photography is not carried out. If electron current I becomes unstable in this state, a high voltage control unit 5 is put into operation, the high voltage source 3 turns off and the electron source 1 is protected. If a switch 7 for photography takes an ON-position, photography begins and a timer 8, syncronizing with that state, begins to operate and opens a switch 6. Usually scores of seconds are given to the setting time. Therefore, since the switch 6 is open while photographing is continuing, the high voltage control unit 5 does not operate even if the electron current I is unstable and secure photographing can be taken.

IPC: H01B17/00
Filed: 1984-04-28
Abstract: PURPOSE:To enable automatic and early detection of fouling of insulator by checking the fouling thereof based on changes in the quantity of light outputted from a photoelectric effect sensor provided between a cap and a pin of the insulator. CONSTITUTION:Light from a light emitting diode 18 is transmitted to an optical fiber 11 by way of cements 4 and 5 of an insulator 6 connected to an insulator chain and a hard ceramics 2 and fed to a photoelectric effect sensor 10 located between a cap 1 and a pin 3 thereof. Light passing through a polarizer 13, a Pockels element 14 and a light detecting element 15 is received with a photodiode 19 through an optical fiber 12. As the fouling of the insulator chain grows, the shared voltage of the insulator 6 rises to reduce the quantity of light outputted from the photoelectric effect sensor 10. Thus, when the level of output signal of an amplification circuit 20 falls below a set value, output of a decision circuit 21 is transmitted to a central monitor chamber from a transmission circuit 22 and a display is given on an alarm display means corresponding to the insulator 6 involved.
