     CONSTITUTION: When an open/close member d 1  is at the upper end of an air exhaust chamber G 1  (I position), the first chamber b 1  and the second chamber c 1  are communicated with each other, and when the open/close member d 1  closes a passing port i, (II position), the first chamber b 1  and the second chamber c 1  are communicated with each other only through an electron beam passing port h 1 , and differential air exhaust operation is possible. Furthermore, when the open/close member d 1  is at the lower end of the air exhaust chamber G 1 , (III position) it closes the upper end of a vacuum pump E 1 , and a vacuum reservoir V 1  is allowed to open to the atmospheric air. By such a constitution, when the open/close member d 1  is set to the (I), the first chamber b 1  and the second chamber c 1  are communicated with each other, and the inside of the vacuum reservoir V 1  can quickly enter the desired low pressure range.

Title: Current type inverter
Inventor: YABU YASUHIKO
IPC: H02M7/5387
Filed: 1991-01-24
Abstract: PURPOSE:To prevent the breakdown by the overvoltage accompanying the off operation of a transistor which constitutes a current type inverter. CONSTITUTION:This is provided with CTs 91 and 92, which detect the currents of transistors 41-44, comparators 101 and 102, which distinguish the existence of those detection outputs, and OR elements 111-114, which operate with the signals from these comparators 101 and 102 and the on-off signals from control circuits 81-84. For example, supposing that the control signal from the control circuit 81 gets on 'L' level of off during the current application of the transistor 41, in this case, CT91 detects the current and the output of the comparator 101 gets on 'H' level. As a result, the output signal of the OR element 111 gets on 'H' level regardless of the signal level from the control circuit 81, and a base drive circuit 71 supplies the transistor 41 with a base current of on continuously. Accordingly, the occurrence of the overvoltage accompanying the off operation during current application of the transistor 41 can be avoided, and the breakdown of the same transistor can also be prevented.
