IPC: F25B1/00
Filed: 1991-04-23
Abstract: PURPOSE:To lower unit requirement of cooling for saving energy. CONSTITUTION:A liquid cooler is provided with a plurality of freezing cycles 21, 22 and 23, each having a temperature inclination and comprising a compressor 24, a condenser 25 and an evaporator 28. The respective evaporators 28 of the respective freezing cycles 21, 22 and 23 are arranged in a cooled liquid flow passage 30 through which cooled liquid flows, in a high temperature order from the upstream side to the downstream side of the cooled liquid flow passage 30. Heat exchange is carried out between the refrigerant which flows through the respective evaporators 28 of the freezing cycles 21, 22 and 23 and the cooled liquid which flows through the cooled liquid flow passage 30. By this, the cooled liquid which flows through the same cooled liquid flow passage can be cooled at evaporation temperature which grading down successively. Thus, the evaporation temperature at which the cooled liquid is cooled can be kept high. Accordingly, necessary volume of the freezing cycles can be decreased, whereby minimization of size becomes possible.

Abstract: PURPOSE: To improve accuracy and reliability in returning a movable portion to the origin by designating a command position within one lattice spacing from the origin to first locate the movable portion of a machine tool at the command position and then locate said portion at an initial lattice point position with a low speed.  
     CONSTITUTION: When table T of a machine tool is set to origin-return mode, origin-return command ZRN is given to NC which thereby designates a command-position within one lattice spacing from the origin to generate distributing pulses CP for locating the table T at this command position. The difference between the distributing pulses CP and feedback pulses FBP from a rotary encorder is counted by a reversible counter RCN 1 , and when the counted value reaches O, NC generates low speed origin-return pulses as CP according to zero signal ZR. Thereafter, the initial lattice point is detected by the zero signal ZERO of a reversible counter RCN 2  to stop the pulse CP.

Title: Low temperature precooler and low temperature cold head interface receptacle
Inventor: BIZUHAN DORI
IPC: H01L39/04
Filed: 1990-04-10
Abstract: PURPOSE: To rapidly cool a superconducting magnet, avoiding excessive thermal stresses by cooling it with a low-temp. refrigerator after pre-cooling the superconductor magnet windings through a heat radiation shield by a two-step low-temp. pre-cooler. CONSTITUTION: With a low-temp. tank 15 and first sleeve 31 held in a vacuum state a coolant, e.g. liq. N is fed from an inlet port 63 to start cooling a cooling tank by a first step heat exchanger 55 of a low-temp. pre-cooler with the coolant flowing in a spiral passage of the cooling tank. A forced convection boiling due to the centrifugal motion of the spiral passage cools a first step heat station 33 and a radiation shield 25. The boiling liq. produces a low-temp. vapor which then enters a second-step heat exchanger 53 of the low-temp. refrigerator to gradually cool a superconducting magnet winding 21 in an initial cooling stage. As the shield 25 is well cooled, a forced convection boiling occurs to rapidly cool the winding 21, thus rapidly cooling the superconducting magnet, without excessive thermal stresses.
