Title: Arrester
Inventor: TAKEKOSHI YOSHIKAZU
IPC: H01T1/04
Filed: 1987-11-30
Abstract: PURPOSE:To facilitate disconnection of arc current, simplify structure and improve performance by inserting an arc current passage produced between electrodes at the time of a thunderstroke into between a pair of oxide high temperature superconductive bodies. CONSTITUTION:Main electrodes 6 are disposed through a gap 7 to let arc current flow between the electrodes at the time of a thunderstroke, while oxide high temperature superconductive bodies 8 are disposed facing each other with the main electrodes 5 between them. The superconductive bodies 8 have Meissner effect, which is property to reflect a flow of magnetic flux. By disposing the superconductive bodies 8 along a passage of arc current, the arc current is reflected by the flow of magnetic flux produced by itself and by Meissner effect by the superconductive bodies 8, and the passage of arc current is elongated as a result, thereby disconnection of arc current can be performed easily. Structure is thus simplified and stability and responsiveness are improved.

IPC: F02C9/22
Filed: 1990-11-07
Abstract: PURPOSE:To detect disconnection of a feedback circuit so as to prevent breakage of an engine parts by detecting the projection 1 retraction amount of a rod communicated with a variable nozzle, and providing an offset voltage to the minimum projection amount detecting value thereof, while judging disconnection of the circuit when the detected value of the rod position shows 0. CONSTITUTION:In an actuator 1, a nozzle opening degree is adjusted by the projection 1 retraction amount of a rod 2 communicated with a variable nozzle VN. The projection 1 retraction amount of the rod 2 is detected by a means 3, and an offset voltage is given to the minimum projection amount detecting value. The projection 1 retraction amount of the rod 2 is determined by a means 4 according to operating condition of an engine, while the projection 1 retraction amount of the rod 2 is feed-back controlled by the means 4 on the basis of a signal from the means 3. Disconnection of a circuit is judged by a means 5 when the detected value of the means 3 is 0. When a variable nozzle is opened fully, namely, when the rod 2 is inserted in the actuator 1, the value of rod position detecting voltage has a prescribed offset value instead of zero(0). It is thus possible to detect disconnection of a feedback circuit by that the value of the rod position detecting voltage becomes 0.

Abstract: PURPOSE:To realize the method for measuring the diameter of a charged-particle beam, which can measure the diameter of the beam simply in high accuracy. CONSTITUTION:A scanning signal is supplied into a deflecting device 2 from a computer 3 by way of a DA converter 4 and an amplifier 5.

In order to perform the oblique scanning, the scanning field of the EB can be rotated by an angle theta, or a base is rotated by a specified angle. As a result, the amount of the data obtained by the scanning at the increment approximately equal to the diameter of the electron beam is increased in comparison with a conventional method. The signal detected with a detector 8 is differentiated with a differentiating circuit 10 and thereafter supplied into the computer 3.
