Title: Solidifying method of sand
Inventor: NAKAMURA TSUTOMU
IPC: B22C1/18
Filed: 1994-01-17
Abstract: PURPOSE:To reuse molding sand by solidifying particles of-sand by using an inorg.-org. composite formed by bringing a water-soluble inorg. compd. and org. high polymer compd. into reaction as a binder, thereby repetitively attaining solidifying and softening. CONSTITUTION:The inorg.-org. composite having a binding effect is formed and is made into a sol state. This composite is uniformly mixed with the sand and thereafter, the moisture of the system is controlled, by which the composite is collected the contact points of the particles of the sand. The hard sand mold is formed by changing the composite to a gel state to exhibit the binding force. Next, the water content of the hard sand mold is increased, by which the gel of the composite is changed to the sol state and the binding force is lost. The sand restores the sate before molding. The composite is produced by bringing water-soluble inorg. compd., for example, magnesium chloride and the org. high polymer compd., for example, sodium polyacrylate into reaction with an aq. system.

IPC: G01R31/34
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To improve the leakage inductance, the fluctuation of the primary and secondary resistance values, and error of an inverter by making no-load tests, DC tests, and single-phase tests in a constant measuring means independent and providing a voltage command selector which selects the voltage commands of a single-phase testing means, a DC testing means, and a no-load testing means. SOLUTION: No-load tests, DC tests, and single-phase tests in a constant measuring means are made to be independent and the voltage commands of a DC testing means 6A, a no-load testing means 6B, and a single-phase testing means 6C are selected by means of a voltage command selector 8. When the selector 8 selects the DC testing means 6A, the means 6A inputs the voltage and current detected by means of a voltage detector 4 and a current detector 3, finds a primary resistance value from the ratio between the detected voltage and current, and outputs the primary resistance to a setting storing means 9. The storing means 9 stores or again stores the primary resistance value in a memory.  Therefore, remeasurement can be performed easily and the leakage inductance and control error of an inverter caused by the fluctuation and errors in the secondary and primary resistance values can be improved.
