Abstract: A heating device for the vaporization of active substances, such as air freshener fragrances, disinfectants, sanitizing agents, insecticides and the like, in which a wick is immersed in a fluid active substance and heat is applied to produce vaporization. The heating is produced by one or more electrical resistance elements embedded in a circular heating ring which is hinged to move over the end of the wick and encircle it. The internal wires which carry electrical current from a source of electrical power are led through the hinged area for connection to the electrical resistance elements, and a feature of the invention is the protection of such wires as they pass through the hinged area.

Abstract: It is an object of the invention to provide a substrate processing equipment that can predict a temperature of a substrate and easily control temperature of the substrate. Formed in a reactor (processing chamber) 3 are four temperature adjustment zones, of which setting and adjustment of temperature can be made by zone heaters 340-1 to 340-4. A temperature controller 4 mixes temperatures detected by inner thermocouples 302-1 to 302-4 and outer thermocouples 342-1 to 342-4 to calculate predicted temperatures of substrates by means of the first-order lag calculation on the basis of time constants of temperatures of substrates heated by the zone heaters 340-1 to 340-4. Also, the temperature controller 4 calculates electric power values (operating variables) for the zone heaters 340-1 to 340-4 with the use of predicted temperatures of substrates to output the same to the zone heaters 340-1 to 340-4.

Abstract: A low-radiation-rate film, made of a material whose radiation rate is lower than that of a heater substrate, is formed at least entirely over the surface of a heat-subject-placing surface of a heater substrate. By applying patterning to the low-radiation-rate film, the exposure rate of the heater substrate is varied such that the radiation rate becomes smaller from the center part of the heat-subject-placing surface toward the outer peripheral part thereof, thereby enabling a uniform temperature across the surface. In addition, the power supply is reduced, thermal stress is eliminated, the wiring design flexibility is increased, and the reliability is increased by preventing short-circuit accidents.

Abstract: A multifunctional griddle having hinged top and bottom heating plate assemblies which receive reversible cooking plates or, alternatively, interchangeable cooking plates for cooking different types of foods such as waffles, pancakes, and hot sandwiches. In one embodiment the reversible cooking plates are nested in face-to-face contact with mating top and bottom heating plates to improve heat transfer to the cooking plates. This is accomplished by forming a mating waffle grid in the heating plates for receiving the waffle iron surfaces of the cooking plates in intermeshing engagement. The intermeshing engagement of the cooking plates with the heating plates also reduces the overall vertical height of the appliance providing a slimmer profile. In an alternative embodiment a set of interchangeable cooking plates is provided having a sliding interface with modified heating plates. In this embodiment the cooking plates are conveniently interchanged to vary the cooking configurations of the appliance.
