  • Patent number: 5207071
    Abstract: There is disclosed a current control apparatus comprising first controllers adapted for detecting an overall or total load current to calculate distribution values for distributing a current margin with respect to an overall or total current limit value to respective air-conditioners; and second controllers adapted for respectively controlling air-conditioners so as not to exceed individual current limit values, and for carrying out an incremental correction of individual current limit values in accordance with distribution values calculated by the first controllers.

  • Patent number: 4958685
    Abstract: A method for plugging the areas of lost circulation occurred during the drilling of a well with the use of a drilling mud, and a lost circulation material to be used therefor. The lost circulation material comprising 1 to 90 parts by weight of a water-soluble solvent containing no active hydrogen atoms and hardly miscible with mineral oils and 10 to 99 parts by weight of a hydrophlic urethane prepolymer, and the method comprises injecting through the drilling pipe the lost circulation material sandwiched by a spacer of mineral oils, so as to allow the lost circulation material to penetrate into the lost circulation areas, to react with water which is present at the areas, and to plug the areas through its polymerization.

  • Patent number: 4866621
    Abstract: An electronic clinical thermometer capable of calculating a prediction value of an optimal equilibrium temperature. The thermometer includes a temperature detection section, an operation section, and a display section. The operation section includes a temperature memory circuit for temporarily storing temperature data detected by the temperature detection section. In addition, the operation section includes a time measuring circuit for measuring the elapsed time of temperature detection and outputting elapsed time data. A parameter calculation section for receiving temperature data and elapsed time data is used to calculate parameters of the equation. Finally, a prediction value calculator is required for calculating an equilibrium temperature according to a predetermined equation using parameters updated by the parameter calculation section.
