Title: Low viscosity flux for centrifugal casting
Inventor: HASEGAWA SOJI
IPC: B22D13/10
Filed: 1994-11-24
Abstract: PURPOSE: To manufacture a tube by the centrifugal casting free from defects on the inner surface of the tube, and excellent in the yield by specifying the content of Al2 O3 , CaO, CaF3 , MgO and SiO2 . CONSTITUTION: The best way to prevent generation of TIN, Al2 O3 and TiO2 causing generation of lump-shaped scum is to completely shut off the molten metal surface from the air. The molten metal can not be completely shut off from the air by the heat generating flux using the thermit reaction which has been the main stream, The cause is that the sufficient viscosity is not obtained because the melting point of the flux is high, and it is effective to adjust the blending of the flux ingredients, and to generate the composite oxides to drop the melting point in order to provide the flux of low viscosity. The flux of low viscosity for the centrifugal casting has the composition consisting of, by weight, 20-30% Al2 O3 , 10-18% Cab, 10-20% CaF2 20-30% MgO, and the balance SiO2 with inevitable impurities.

IPC: H02H7/097
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To provide an ultra-low temperature refrigerator, in which abnormal operation of a motor for driving a refrigerating unit can be adjusted adequately and at the same time, abnormality in the refrigerating unit can be detected. SOLUTION: A refrigerating unit 80 generates an ultra-low temperature by expanding a refrigerant 65 after the refrigerant 65 is compressed by a compressing unit 60. A three-phase motor 82 is used to drive the refrigerating unit 80. When abnormality in phase connection is detected by a difference in two phases (R.S) of a three-phase power supply 30 for a three-phase motor 82, two phases are changed by a phase-change relay circuit 52 to turn the operational condition to a normal state. After the turn to the normal state, the pressure of a refrigerant 65 is measured by a pressure detector D1. If a given change in pressure is not detected, an alarm of a defect in the three- phase motor 82 and its winding part is generated.  In normal operation of the three- phase motor 82, a temperature at the refrigerating unit 80 is detected by a temperature detector D2, and an alarm of defect in the refrigerating unit 80 is generated if a given change in temperature is not detected. In addition, when the refrigerant 65 from one compressing unit 60 is fed to a plurality of refrigerating units 80, the detection and the alarm generation are carried out for each three-phase motor 82 and for each refrigerating unit 80.

Abstract: PURPOSE:To enable early discovery of a damage of a gear and output of an abnormality signal by detecting by a sensor an acoustic emission (AE) generated from a tooth surface in a state of engagement of the gear rotating. CONSTITUTION:When gears 1 and 2 are worn or damaged, an abnormality occurs in AE generated from the tooth surfaces of the gears 1 and 2 in a state of engagement, and it is detected by a sensor 7 provided on a support part 6 of a rotating shaft 5 of the gears 1 and 2 and sent to an arithmetic control device.
