PURPOSE:To improve an efficiency of operation by a method wherein a temperature detector and an electronic temperature adjuster element are arranged on a table block, and a temperature of the table block is adjusted to a desired value in a short period of time. CONSTITUTION:Temperature of the table block 13 is sensed by a thermocouple 22 and always compared with a desired temperature set by a temperature setting means 24. Either a positive or a negative voltage is applied to an electronic temperature adjustor 21 from the temperature adjuster 23 so as to make difference zero, the electronic adjustor element is operated as a heater or a cooler and the table block 13 is kept at a desired temperature. With this arrangement, the treated material 12 on the table block 13 is heated through a thermal condition from the table block 13, rapidly increased to reach to the desired temperature in a short period of time and stabled. Thus, a working efficiency may be improved more. |
