Title: Ion source electric-discharge power supply device
Inventor: HAYASHI KENICHI
IPC: H01J27/02
Filed: 1984-03-01
Abstract: PURPOSE:To enable the detection of metal arc electric-discharge to be easily performed by detecting discharge voltage by means of a voltage detector and by comparing the detected discharge voltage with the preset reference voltage. CONSTITUTION:Electric discharge voltage is monitored by a voltage detector 15 before being used as one of the inputs to a comparator 16. A reference voltage set by a field generator 17 is used as the other input to the comparator 16. The reference voltage is set for a level near 30V which is an intermediate level between the initial voltage of gas electric discharge and the metal arc electric-discharge voltage. When metal arc electric discharge occurs between one of hot cathode filaments 4a, 4b...4g and an anode electric-discharge case 5, discharge voltage decreases to a level lower than the reference voltage and therefore the output of the comparator 16 is reversed. The change in the output of the comparator 16 is detected by a switching-element-driving circuit 14 to drive a switching element installed in a discharge power supply 1 thereby interrupting the discharge current.

While a mass-flow controller MFC is used, also the valves are closed. A pressure by a differential pressure gage 18 at this time is designated as P1 . Thereby, a pressure between the isolation valve 12 and the main valve 13 is maintained to be always constant, and also a pressure inside a vacuum chamber 11 is maintained.  However, when leak is generated in the vacuum camber 11 with the passage of time, a pressure between the vacuum chamber 11 and the differential pressure gate 18 is raised, and a difference is generated in the pressure between the isolation valve 12 and main valve 13 and in the pressure inside the vacuum tank 11 is generated. A pressure by the differential pressure gage 18 after the passage of a definite time is designated as P2 , a discharge gas amount is calculated by a relational expression, it is subtracted from a measured result, and the leak of the vacuum chamber 11 can be detected on the basis of the value.

Title: Power supply device
Inventor: KISHI SHIGERU
IPC: H02M7/06
Filed: 1990-02-21
Abstract: PURPOSE:To reduce the loss of a reactor so as to attain its miniaturization by providing a constitution such that only an input current based on on-off control of a semiconductor switch element is allowed to flow in the reactor and directly to DC side not through the reactor in a period except the above mentioned. CONSTITUTION:Energy is accumulated in a reactor 3-b by turning on a semicon ductor switch element 2 to short-circuit an AC power 5 through a reactor and by generating a forced flow of an input current. When the current in the reactor reaches a predetermined value, the accumulated energy in the reactor 3-b is emitted to a capacitor 4-b through a diode 1-g by turning off the semiconductor switch element 2. The input current can be forced to flow by repeating such on-off operation as obtained of the semiconductor element 2. In this way, a conduction factor of the current, flowing in the reactor 3-b, can be decreased.

Filed: 1988-02-23
Abstract: PURPOSE:To form an image scanner with simple structure and less fault by moving a movable reflection part and a photodetection part at an equal speed in opposite directions to each other. CONSTITUTION:When a rotational force of a motor is delivered to pulleys 5, 6, toothed belts 7, 8 are driven in the X direction of the arrow. Thus, the 1st mirror 26 is moved toward the arrow X along the direction of an original G. On the other hand, a moving unit 30 is moved in the direction Y. That is, the 1st mirror 26 and the moving unit 30 are moved at an equal speed in opposite directions. Since they are driven at an equal speed, number of parts is less and a conventional ring belt may be used. Since a moving base 22 and the moving unit 30 are arranged in the vertical position, the structure is made compact.
