Abstract:
ABSTRACT Disclosed is a temperature control apparatus including: a resistance heater to have a characteristic such that a resistance value of the resistance heater changes dependently on a temperature thereof; a signal generator to output a control signal having two voltage levels of an on-voltage and an second-voltage; a switching section to flow a first current through the resistance heater when the voltage level of the control signal is the first-voltage, and to flow a second current having a current value smaller than that of the first current through the resistance heater when the voltage level of the control signal is the second-voltage; and a voltage measuring instrument to measure a voltage value across the resistance heater at the time when the second current flows through the resistance heater, wherein the signal generator controls the temperature of the resistance heater based on the voltage value measured by the voltage measuring instrument.

A temperature control apparatus includes a resistance heater whose a resistance value changes depending on a temperature of the resistance heater; a signal generator to output a control signal having two voltage levels including a first-voltage and a second-voltage; a switching section to flow a first current through the resistance heater when the voltage level of the control signal is the first-voltage, and to flow a second current having a current value smaller than that of the first current through the resistance heater when the voltage level of the control signal is the second-voltage; and a voltage measuring instrument to measure a voltage value across the resistance heater at the time when the second current flows through the resistance heater. The signal generator controls the temperature of the resistance heater based on the voltage value measured by the voltage measuring instrument.

PROBLEM TO BE SOLVED: To use liquid in a bag to be substantially to the maximum. SOLUTION: A liquid storing container 1 has a form of a hexahedron when expanded. The container 1 includes a first flexible bag 3 storing the liquid, and a second flexible bag 4 piled up on the entire upper surface of the first flexible bag 3 including the corners of the upper surface. When the liquid in the first flexible bag 3 is discharged, liquid the temperature of which is higher than that of the liquid in the first flexible bag 3 is introduced into the second flexible bag 4.

PROBLEM TO BE SOLVED: To provide a heat insulating container which secures a temperature difference between reacting parts of a reactor including two or more reacting parts. SOLUTION: The heat insulating container 30 houses the reactor 10 including the two or more reacting parts 11, 12 having different temperatures. The inner wall surface of the heat insulating container is composed of two or more regions having different infrared reflectances, and the reacting part having a lower temperature is arranged on the region side having a lower infrared reflectance. Heat dissipation from the reacting part having the lower temperature is promoted, and the temperature difference between the reacting parts of the reactor including two or more reacting parts can be secured.
