Filed: 1991-07-08
Abstract: PURPOSE:To reduce heat intruding into a current lead by a method wherein the amount of gas of vaporization of liquid helium gas and the amount of circulating gas of helium gas are controlled in such a way that the amount of the circulating gas of the helium gas into the current lead is controlled at the amount of circulating gas exceeding the amount of current conduction time gas, which is decided by a self-cooling condition at the time when a rated current is made to flow through the current lead. CONSTITUTION:A control circuit 23 of a control means 21 monitors a temperature change in a lead 4 on the side of a high temperature through a temperature sensor 12 to output a control signal 13A for the amount of circulating gas and a control signal 23B for the amount of gas of vaporization of liquid helium gas. A heat power supply 25 controls a current in a heating unit 24 arranged in the liquid helium gas on the basis of the signal 23B. In the case heat (p) intruding into a vacuum heat-insulating vessel is little and a desired amount Q of the circulating gas is not obtained, a control condition is set so that the unit 24 vaporizes the liquid helium gas to supply the amount of the shortage. Thereby, a current lead 3 is forcedly cooled and heat of intrusion into the lead 3 can be reduced.

IPC: B21D3/10
Filed: 1984-08-09
Abstract: PURPOSE:To straighten accurately the warpage in longitudinal direction by forming a dent on the face of one side of an angle steel and by straightening the warpage in a longitudinal direction of other sides with the movement of the material in the outer direction of the dent in such case. CONSTITUTION:The other side 14 of an angle steel 7a is placed on a table 3 and the dent forming position 15 which is shifted in the width direction from the medium position in the width direction of the other side 14 is located immediately under a punch 8. A hydraulic oil is fed to a hydraulic cylinder 5 with giving a command to an oil pressure circuit 10 via a control circuit 11 by an operation part 12 and the punch 8 is descended. The punch 8 forms a dent on the plate face of the angle steel 7. In case of forming the dent the straightening condition of the angle steel 7 is dscriminated by a linear gage 4 due to the plastic deformation moving the material of the angle steel 7 in the outer direction of the dent being caused. The pressing by the necessary quantity is then performed by the punch 8. The following dent is thereafter formed with shifting the angle steel 7 so that following dent forming position 15 can correspond to the punch 8. The warpage in longitudinal direction is thus corrected.

Title: Fluid pressure type holding unit
Inventor: ANDOU ISAO
IPC: B23B31/117
Filed: 1980-11-27
Abstract: PURPOSE: To obtain an adequate holding force at any time and maintain this force free from any change of ambient temperature by preventing generation of an excessively large fluid pressure in the fluid chamber of a holding unit.  
     CONSTITUTION: The sleeve of a chuck body is pressed to touch the portion to be held by having a thin wall portion expanded toward the axle center of a through hole when some oil pressure is generated in an oil chamber and the object to be held is practically held. Then, the oil quantity in the holding unit is limited to a small amount due to existence of a spacer ring and spacer rods 23, 24, and when the oil pressure exceeds the set level the pressure is to be absorbed by electric deformation of Belleville spring 33 due to the existent constitution, and as the characteristic of said spring is so determined to yield no excessive oil pressure within the range of normally generated temperatures, any change of the ambient temperature is not supposed to exert any influence, thus a proper holding force can be obtained at any time.
