摘要： In order to increase the flow rate of coolant liquid supplied to the nozzle (88) of a plasma torch (10) and to extend the life of the plasma torch (10), within the plasma torch (10), an electrode coolant liquid passage (60, 84, 85, 86, and 64) which supplies coolant liquid to an electrode (80), and a nozzle coolant liquid passage (56, 70, 92, 72 and 68) which supplies coolant liquid to the nozzle (88), are provided separately as independent coolant liquid passages which extend in parallel, and which are mutually electrically insulated from one another. Moreover, the flow rate of coolant liquid in the nozzle coolant liquid passage is greater than the flow rate of coolant liquid in the electrode coolant liquid passage.

摘要： A disc heater is applied to a temperature control apparatus which controls a temperature of an object to be processed on at least one surface thereof. In the disc heater, wire-like heating elements are laid on a plate surface in a predetermined pattern and power feeding portions are disposed at ends of the wire-like heating elements. The pattern formed by the wire-like heating elements comprise a large number of arc portions disposed on a large number of concentric circles, and a surface area of the arc portions is 70% or greater, more preferably, 85 to 95% of a surface area of the entire pattern. With this feature, it is possible to effectively reduce the local excessively heated portion to the utmost, and to uniformly heat the entire heating surface, thus realizing an ideal topology pattern of the disc heater.

摘要： Object of the present invention is to provide uniform heat distribution to a substrate undergoing heat treatment on top of a heat exchange plate. A heat exchange plate 1 is a flat, circular receptacle, has a cooling liquid inflow opening 11 on one end and outflow opening 13 on the other end, and cooling liquid flows on the inside. The surface of the plate 1 is divided, for example, into four zones having different heat capacities and heat transfer characteristics, and an independently controllable foil heater 21A, 23A, 25A, 27A is attached to each zone. Heater 21A covers a zone, which circumferentially surrounds a substrate placed on top of a plate, heater 23A covers a zone directly beneath a substrate, heater 25A covers a zone of the vicinity of the outflow opening 13, and heater 27A covers a zone of the vicinity of the inflow opening 11. Temperature sensors 31-33 are disposed on the inside of a plate at four locations of a second zone, which are apt to receive the affects of the first to fourth zones. Based on each plate temperature detected by the temperature sensors 31 to 33, a temperature of the substrate at a location corresponding thereto is estimated.
