Title: Operation control device for refrigerator
Inventor: OGATA HIDEO
IPC: F25D11/00
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To provide an operation control device for a refrigerator in which the number of failures in starting a DC electric motor is reduced by a method wherein an energization of the DC electric motor is avoided in the case that a high load torque is applied to the DC electric motor at the time of starting energization of it. SOLUTION: Whether or not a freezing cycle 2 is made stable from a time just after stopping of a DC electric motor 7 to a state in which a compressor 5 can be energized is discriminated by a first freezing cycle stabilization discriminating means 17 on the basis of data attained from a discharged gas pressure sensor 16. In the case that it is not in a stable state, the compressor 5 is not energized even if an output signal of a refrigerator temperature control means 15 is produced and at the same time a refrigerator fan 6 is operated at a high speed. With such an arrangement as above, it is possible to avoid an energization of the DC electric motor 7 in the case that a high load is applied to the DC electric motor and so the number of failures in starting the DC electric motor becomes less.

Abstract: PURPOSE:To perform the improvement of the detecting speed and the increase in the effectively inspecting range by emitting laser lights at positions to be compared to the surface of a wafer with relatively large diameter spot, detecting and comparing totally the intensities of the lights, thereby dividing the picture elements of a picture image and detecting the defect of the pattern without comparison. CONSTITUTION:When laser lights 12, 13 from a laser oscillator 10 are emitted to the same patterns of pellets, they are spot emitted, since the lights 12, 13 have relatively large luminous flux diameter, to enclose the patterns 11A, 11B of the pellets. When scanned over the entire length of the pellets, the reflected lights from the pattern edges are sequentially inputted to photodetectors 14A, 14B and 15A, 15B. Accordingly, the photodetecting signals of the photodetectors 14A, 14B and 15A, 15B can be detected. When a defect is produced on the pattern 11B, incoincidence part of both signals is presented. Accordingly, a detection arithmetic unit 16 which inputs the photodetecting signals of the photodetectors 14A, 14B and 15A, 15B detects the incoincidence part of both signals, thereby detecting the disagreement of the pattern of the both pellets.

Abstract: 1383734 Wet separation of particular materials CRANE CO 30 Jan 1973 4648/73 Heading B2H Particulate mixed, e.g. spent, ion exchange resins are reclassified into separate cation and anion exchange resin fractions by introducing the mixed resins into the top of a vertical column of liquid in which the cation and anion exchange resins settle at different rates of. fall, thereby separating into distinct fractions which are separately collected, the reclassification being enhanced by maintaining a laminar downward flow of liquid in the vertical column. The laminar flow of liquid operates to streamline the particulate resin flow and limits random vertical movement of the particles resulting in a reduction in the total number of particle collisions. Moreover the downward flow of liquid enhances the settling of the larger as compared with that of the smaller particles: The liquid used is preferably water and the laminar flow has a Reynolds number of between 200 and 2200. A resin-receiving vessel is preferably provided above, and adapted to communicate with, the vertical redassification column and an upward current of liquid is set up in this vessel to effect backwash of the resins to remove the fines and/or preliminary redassification of the resins prior to their passing from the vessel into the column. Reclassification may also be enhanced by increasing the buoyancy of one of the types of resins in the vertical column by maintaining a dispersion of air bubbles in the liquid therein and contacting the particulate resin with a hydrophobic, aerophilic flotation agent which selectively adheres the cation or anion resin to the air bubbles. Flotation agents specific to anion exchange resins may include a polyamine alkyl sulphate, xanthate, dithiophosphate, dithiocarbamate or an arenesulphonate. Flotation agents specific to cation exchange resins may include a polyacrylamide, primary amine, quaternary amonium salt, primary ammonium, alkyl-pyridinium salt or a thiocarbanilide. A suitable plant is described.
