Title: Production unit for single crystal
Inventor: MATSUTANI KINYA
IPC: C30B15/00
Filed: 1983-07-05
Abstract: PURPOSE:To miniaturize an electromagnet, to make it inexpensive, and to demount it easily, by providing the electromagnet of a superconductive magnet to impress a magnetic field on melt liquid level of raw material of single crystal, so that the desired magnetic field is impressed on the melt liquid level only, and it has no influence of leakage magnetic field on the other parts. CONSTITUTION:The superconductive electromagnet 12 is used to impress a magnetic field on the melt liquid level 6 of raw material of single crystal. Since high current is made to flow through a thin superconductive wire, an extremely small-sized electromagnet is used to provide the same magnetic field intensity compared with an existing normal electrically-conductive electromagnet. Consequently, the zone influenced by the magnetic field becomes narrower, strong magnetic field is impressed on the solid-liquid interface (melt liquid level) 6 only, the influence of leakage magnetic field has almost no influence on the other parts such as the pulling driving mechanism 5, so that malfunction of motors used in the pulling driving mechanism 5 caused by the leakage magnetic field can be avoided. Consumed power is extremely reduced. Further, since the electromagnet part is miniaturized, the maintenance and inspection of crucible and demounting of the superconductive electromagnet during cleaning are carried out easily and maintenance operation is made easy.

IPC: H01J37/08
Filed: 1989-05-17
Abstract: PURPOSE:To prevent generated gas from leaking into an ion emitting section when an ampule is broken by constituting the ruptured section of the ampule to be in a vacuum condition independently from the ion emitting section. CONSTITUTION:The inside of a container 11 is evacuated by a sorption pump 41, and is furthermore evacuated into an ultra high vacuum condition by a sputter ion pump with valves 30 and 31 closed. At this place, an ampule 7 is broken with valves 33 and 34 closed, after that, emitting gas from the ruptured section 6 of the ampule is sufficiently exhausted by the sorption pump 41 only with a valve 32 released. Successively, the valve 32 is closed so that the degree of vacuum is furthermore increased by the sputter ion pump 40 with the valve 33 released. In this case, when the valve 34 is released, ion materials flowing out of the ampule 7 pass through a duct 8 so as to flow into a reservoir 3.

Title: Piled detecting device for reclaimer
Inventor: TANIYOSHI SHUICHI
IPC: B65G65/16
Filed: 1993-05-24
Abstract: PURPOSE:To make automatization concurrently serve as a turn inverting function and a step switching function by hanging down a distance sensor, mounting a balance weight so as to obtain a fixed tilt angle of directivity relating to a horizontal surface, in the point end right/left of a boom. CONSTITUTION:A distance sensor, for instance, an ultrasonic sensor 2 is mounted respectively on the right/left in the vicinity of the point end of a boom 33 of a reclaimer. This ultrasonic sensor 2 has a fixed tilt angle alpha of direction relating to the perpendicular line. A balance 3 is fixed to the ultrasonic sensor 2 so as to obtain the center of gravity in a direction at a 90-alpha degree to the direction of the ultrasonic sensor 2. Hanging down is performed by using a chain or a link so that the balance weight 3 is always directed to the perpendicular downward. By this method, regardless of any elevation angle of the boom 33, by the balance weight 3, the direction of the ultrasonic sensor 2 holds the fixed tilt angle alpha relating to the ground surface. Thus by only two sets of the distance sensors 2, automatization can be attained of a turn inverting function and a step switching function.

Filed: 1987-05-18
Abstract: PURPOSE:To complete a regenerating cycle in a short time by installing a regenerating nozzle which performs a gas purge on a gaseous molecule adsorption plate face in a cryopump uniformly. CONSTITUTION:The purge gas fed out of a purge gas intake 1 is carried up to the vicinity of each side of a 15K cryopanel 3 and an 80K shield 4 by an inlet pipe 2, and it is blown toward both sides of the 15K cryopanel 3 and a cold head 6 from a purge gas blowoff port 5, while the adsorbed gaseous molecule blows between an outer panel 8 and an outer side face of the 80K shield 4 from an 80K baffle 7 by dint of the purge gas, then it is discharged out of an exhaust port 9. Simultaneously, the purge gas out of a purge hole 10 is exhausted to the outside of a pump from the exhaust port 9 as blowing the cold head 6. Thus, since gaseous molecule removal by the purge gas advances quickly, regenerating time is sharply reduced.

Title: Device and method for heating end of hot sheet bar
Inventor: YOSHIDA KUNIO
IPC: B21B45/00
Filed: 1990-05-11
Abstract: PURPOSE:To obtain the products of the uniform quality of the material with a high yield by arranging the heating device of operating side and the heating device of driving side on the right and left to the center of the transferring line for the sheet bar and arranging the aprons among the transferring rollers at the place of non-existing the heating device except the central part of the transferring line. CONSTITUTION:The driving side heating device 12 and the operating side heating device 13 are arranged at the right and left to the center of the sheet bar transferring line. Because the apron for preventing the sheet bar from creeping into is arranged except the central part of the transferring line, each heating device is movable to the central part in the sheet bar width direction. Therefore, the central part in the sheet bar width direction of the top part of the longitudinal direction of sheet bar which is impossible to be heated until now can be also heated. On the result that the longitudinal direction and the width direction of the sheet bar are also made together in the uniform temperature state, the uniform products can be obtained. Therefore, because the length of the defective part of the material of the top which is cut down until now can be reduced by half, the yield of the products is also improved remarkably.

Abstract: PURPOSE: To detect the deterioration of a magnetic disk medium, by comparing the read signal given from a magnetic disk with the reference voltage.  
     CONSTITUTION: A voltage comparator compares the voltage of the read signal given from a magnetic disk with the reference voltage. For instance, a head 2 shifting through a head drive part 3 as well as the part 3 are controlled by a command given from a central processor 10. Then the signal voltage given from a floppy disk control part 4 where the data is read and written and from a floppy disk medium 1 and supplied from the part 4 are compared with the voltage given from a constant voltage generating part 7 through a voltage comparator 6, and the result is displayed at  a display part 5. The voltage of the read signal lowers with deterioration of the medium 1. Thus the degree of deterioration can be decided.
