Title: Superconducting coil system
Inventor: KUBO MORIHIRO
IPC: H01F6/02
Filed: 1989-07-07
Abstract: PURPOSE:To completely break a current when a superconducting coil, which is continuously driven by a large DC current, by a method wherein the period in which a current is allowed to flow through a DC circuit breaker is limited to the time of quenching generation only. CONSTITUTION:When a normal driving is conducted, a DC circuit breaker 4 is disconnected, a DC large current I0 is continuously applied to the switch 6 having a microscopic fixed resistor 5. When the generation of quenching of a superconducting coil 1 is detected by a quenching detector 7, the DC circuit breaker 4 is turned ON by a control circuit 8. When the circuit breaker 4 is turned ON, most of the DC current I0, which has been flowing through the switch 6, is allowed to flow to the circuit breaker 4. Then, when the current detector 9 detects that the current flowing through the switch 6 is nearing zero, the switch group 6 is turned OFF by the control circuit 8. After the above- mentioned series of movements has been finished, the DC current is broken by the circuit breaker 4 by the command sent from the control circuit 8.

By the diffusion, the crosslinker-containing resin film in the interfacial region between the photosensitive resin and the crosslinker-containing resin film is brought into crosslinking reaction to form a reacted layer 10. The crosslinker-containing resin film 9 is removed while leaving the reacted layer 10. An unnecessary transferred pattern 7 in the pattern transferred to the photosensitive resin is eliminated by the reacted layer.

IPC: G01B11/00
Filed: 1985-08-09
Abstract: PURPOSE:To enable the detection of an exact position even from an image of position information containing noise, by extracting the rising and falling portions from data taken in an image memory and by obtaining coordinates approximate to the positional relationship of a desired pattern based on the extracted data. CONSTITUTION:Signals being present on a detection line are extracted from an image information within a visual field caught by an ITV camera and are taken in an image buffer memory. Since a random signal component of high frequency is contained in a signal waveform, the signals are smoothed by a spatial operator of an appropriate size. From smoothed signal component the continuously rising or falling portion is extracted. Then, the beginning or ending point of the falling or rising portion forming a root portion is numbered according to the positional relationship of a pattern nearest to mark element for matching position, and thus coordinates approximate to the positional relationship of the pattern is obtained.

CONSTITUTION:By a pressure pump 1, hot water 1a contained in a bathtub 10 is sucked into a duct 4 from a suction port 2. By interlocking therewith, solenoid valves 5a', 5b' of a carbon dioxide supply tube 5a and an air supply tube 5b are opened, and by an ejector effect, air and carbon dioxide are sucked into the duct 4 and mixed with the hot water 1a, and pressurized and dissolved. It is necessary to supply gas excessively in order to enhance the dissolving efficiency, and an accumulator 6 not only absorbs a ripple of the hot water 1a but also quickens to dissolve air and carbon dioxide, and also, separates surplus gas from the hot water 1a. When the hot water 1a in which gas is dissolved with high concentration is exhausted into the bathtub 10 from an exhaust port 3, minute bubbles are generated in the hot water 1a contained in the bathtub 10. In such a way, it can be prevented that carbon dioxide is brought to pressure reduction and becomes large bubbles, and ascends quickly.
