摘要： A method of making a heater includes an aluminum nitride base having equal to or less than 1% impurities, particularly one embodiment having none of polybrominated biphenyl, polybrominated diphenyl ether, hexabromocyclododecane, polyvinyl chloride, chlorinated paraffin, phthalate, cadmium, hexavalent chromium, lead, and mercury. The base is fired in a heating unit before any layering. Thereafter, on a topside and backside of the base a conductor layer is layered and allowed to settle and dry before firing. Next, a resistive layer is layered on the base from a resistor paste such that the resistive layer connects to the conductor layer on the topside. The resistor paste is allowed to settle and dry and then the base with the conductor and resistor layers is fired. At least four layers of glass are layered next over the resistive layer, each instance thereof including layering a glass, drying the glass and firing.

摘要： A cooking device according to one example embodiment includes a base having a top surface positioned to contact a cooking vessel configured to hold food during cooking. The base includes a heater having a ceramic substrate and an electrically resistive trace on an exterior surface of the ceramic substrate. The heater is positioned to supply heat generated by applying an electric current to the electrically resistive trace to the top surface of the base for heating the cooking vessel to heat food in the cooking vessel. In some embodiments, the electrically resistive trace includes an electrical resistor material thick film printed on the exterior surface of the ceramic substrate. In some embodiments, the electrically resistive trace is positioned on a top surface of the ceramic substrate that faces upward toward the top surface of the base.

摘要： Methods and apparatus include a hair iron having a controller and a heater between first and second arms movable relative to each other between open and closed positions. The controller connects or not the heater to a line voltage to heat hair when placed between the arms during use. A proportional-integral-derivative (PID) controller communicates with a thermistor measuring a current temperature of the heater and makes requests of the controller to operate the heater at a setpoint temperature. In various embodiments, the heater heats to full power during warm-up and operates thereafter at lower temperatures based on a reading of the line voltage and a time to adjust the current temperature to the desired setpoint temperature.

摘要： A heating assembly according to one example embodiment includes a thermally conductive heat transfer plate and a plurality of modular heaters mounted to the heat transfer plate. Each modular heater includes a ceramic substrate having at least one electrically resistive trace thick film printed on the ceramic substrate and at least one electrically conductive trace thick film printed on the ceramic substrate. Each modular heater is configured to generate heat when an electric current is supplied to the at least one electrically resistive trace, and the heat transfer plate is positioned to transfer heat from the plurality of modular heaters for heating a desired heating area.

摘要： Methods and apparatus include a hair iron having a ceramic heater between first and second arms movable relative to each other between open and closed positions. The ceramic heater has resistive traces that heat up hair during use upon being connected to a power source. On a side of the ceramic heater opposite the resistive traces, a layer of metal is formed to spread out during use the heat from the resistive traces. The metal may be formed as a single or multiple layers. The composition of the metal can be, representatively, pure or alloys of silver, copper, or aluminum with platinum or palladium. The shape of the metal varies as does its coverage on a surface area of the ceramic heater.
