Abstract
The disclosure relates to a ceramic heating device in the form of a cylindrical shape comprising a burnt cylindrical support core of heat-resistant ceramics, a ceramic element disposed around said support core, said element comprising (i) a burnt sheet of heat-resistant ceramics; (ii) a heat-generating resistor pattern, said pattern being hermetically sealed between said sheet; and (iii) a pair of exposed terminals provided onto said sheet and said core, said terminal being connected to said pattern and adapted to be coupled to power leads such that electric power is then applied to said pattern.
Claims8
A cylindrical ceramic heating device comprising:
- a burnt cylindrical support core of heat resistant ceramics;
- at least one burnt heater element made of heat resistant ceramics disposed around said support core in contact with the periphery of said support core, said element comprising a burnt sheet of heat resistant ceramics;
- a heat-generating electrical resistor pattern formed from a resistive paste and fired on said ceramic sheet, said pattern being hermetically sealed between said sheet and said core;
- and
- a pair of exposed terminals disposed on said sheet, said terminals being connected to said pattern and adapted to be coupled to power leads such that electrical power is applied to said pattern;
- said support core being a hollow cylinder and the hollow thereof being adapted to form a means to connect with a cylindrical article to to heated.
