Title: Fluid temperature control device and method
Inventor: SATO TOMOHISA
IPC: F24H1/10
Filed: 2000-12-04
Abstract: PROBLEM TO BE SOLVED: To provide a fluid temperature control device capable of meeting the solid difference of a flow control valve, effectively suppressing an overshoot and completely meeting the disturbance of a load. SOLUTION: Working fluid is cooled by cooling water in a heat exchanger 106, and then, heated by a lamp heater 108 to obtain desired temperature. For the control of the flow control valves 112 and 114 of cooling water, two kinds of tables, are used, including a table for compensating the nonlinear cooling characteristics of the heat exchanger 106 and a table for compensating the nonlinear flow characteristics of the proportional valves 112 and 114. The table for compensating the characteristics of the proportional valves defines a rate of change of flow relative to each position of the number of pulses which is generated upon movement of the number of one pulse from the position.  The table for compensating the characteristics of the proportional valves is adapted to the characteristics of each proportional valve by applying a parameter showing the sold difference of the proportional valves. During transient time, the proportional valves are controlled in accordance with the changing speed of current temperature. Upon setting, the proportional valves are controlled so that the output of the lamp heater 108 is located within a proper output range.

Title: Signal-processing device and method of thermocouple, and heat-treating device
Inventor: SUZUKI FUJIO
IPC: G01K7/02
Filed: 2000-12-06
Abstract: PROBLEM TO BE SOLVED: To rapidly and accurately measure temperature after a thermocouple is connected, when the thermocouple for inspecting the temperature is disconnected or removed. SOLUTION: One end side and both the ends of the thermocouple are connected to the input end of an operational amplifier. A capacitor for low-frequency filters is connected between the input ends. Also, a D/A converter is connected to the other end side of the thermocouple, and a voltage of +2 V for detecting disconnection is applied from it. Since the impedance of the thermocouple is small, the electromotive force of the thermocouple is normally applied to the operational amplifier. However, in the case of a disconnected state, the capacitor is charged by +2 V, and the voltage at the input end increases for detection.  After a prescribed voltage has been reached, a negative voltage, for example -2 V, is supplied from the D/A converter to one end side of the capacitor, the charging electrical charge of the capacitor is rapidly discharged to the D/A converter side, and the supply voltage of the D/A converter is set to 0 V, when the voltage across the capacitor reaches 0 V.
