摘要： A variable wattage control system is disclosed for providing varying wattage levels for a power-receiving device. The power-receiving device is operatively associated with a sensing means that communicates with a temperature controller for comparing the sensed temperature with a predetermined set point. If the sensed temperature falls outside the set point, the temperature controller directs a power control means to turn on the heating element at a specific wattage level. The variable wattage control system may include a micro-controller contained in either the temperature controller, power controller or a separate module which determines a power output scaling factor based on the percentage of the full line voltage being applied to the power-receiving device and then scaling the power output. The power output scaling factor determines the maximum percentage power to be applied to the power-receiving device such that a single device may be driven at different power levels for various applications.

摘要： A heater device (10) used for mold injection processes and related method for manufacturing the same is disclosed. The heater device (10) comprises an inner sleeve (12) having a hollow tubular body with opposed flanges (36) formed at either end thereof and a resistive element (16) wound around the body of the inner sleeve (12). In assembly, the inner sleeve (12) is disposed inside and engaged to an outer sleeve (14) having a hollow tubular body with opposed openings (50, 52) that communicate with a cavity (46) defined between the inner and outer sleeves (12, 14). The outer sleeve (14) further defines a first aperture (44) for permitting connection of terminal leads to the resistive element (16) inside the outer sleeve (14) during manufacturing. During manufacture, a slurry of ceramic insulation material (62) is injected through a second aperture (45) in order to completely fill the cavity (46) and encase the resistive element (16).

摘要： An apparatus (10) for splicing a heatable section (20) of a tubular heater (12) to a cold section, (22) with the heatable section (20) having an outer sheath (78), which has a heating element (84) therein, while the cold section (22) has an outer sheath (88) which includes a cold pin (94). The apparatus (10) comprises an enclosure (12) defining a chamber (62) which further defines opposed openings in communication with the chamber (62). A welding tip (130) extends into the chamber (62) and is capable of melting the cold pin (94) and welding the ends (80,90) of the heatable and cold sections (20,22) together in a splicing operation.

摘要： A hot runner nozzle heater system is provided with a layered heater in communication with a two-wire controller, wherein a resistive layer of the layered heater is both a heater element and a temperature sensor. The two-wire controller thus determines temperature of the layered heater using the resistance of the resistive layer and controls heater temperature through a power source.

摘要： An improved heating system (10) for heating a semiconductor wafer during fabrication in a corrosive manufacturing environment is disclosed. The system (10) includes a novel ceramic heater (12) made of layered ceramic substrate (16) that has a plurality of heating elements (44) and temperature sensor arrangement (38) completely and directly embedded within the ceramic substrate (16) of the ceramic heater (12). The heating elements (44) and the temperature sensor arrangement (38) are constructed of a molybdenum and aluminum nitride composite that provides a low temperature coefficient of resistance which improves the operating efficiency of the ceramic heater (12). In operation, the temperature sensor arrangement (38) transmits temperature readings to a microprocessor (14) capable of controlling the heating elements (44) in such a manner as to provide a constant and uniform temperature distribution along the entire surface of the semiconductor wafer.
