摘要： A heater for heating a moving sheet material by contact therewith is used, for example, in electrophotographic apparatus for fixing toner to printing paper. The heater comprises an insulating substrate formed with a striplike heating element on its upper surface, and a support plate for supporting the substrate. A higher heat preserving property is given to the opposite end portions of the heating element than to a longitudinal intermediate portion thereof to thereby compensate for a temperature reduction at the element end portions and make the heating element uniform in temperature over the entire length thereof.

摘要： A heater comprises an insulating substrate which carries a parallel pair of conductor strips. The respective conductor strips are spaced from each other transversely thereof but electrically connected to each other by a plurality of heating resistors which are spaced longitudinally of the respective conductor strips. Advantageously, the heating resistors are arranged or configured so that the heater will have a temperature distribution which is equalized longitudinally.

摘要： A heater for a sheet material comprises an insulating substrate and a main resistor strip formed on the substrate. The substrate is further formed with auxiliary resistor strips adjacent to both ends of the main resistor strip. In operation, the main and auxiliary resistor strips are actuated simultaneously for heat generation. As a result, the additional heat generated by the auxiliary resistor strips compensates for higher heat dissipation at both ends of the heater, thereby equalizing the temperature distribution longitudinally of the heater.

摘要： A method is provided for making unit heads from a material head. The unit heads are used to constitute a divisional-type thermal head. The material head includes an elongate insulating substrate carrying a longitudinal array of heating dot portions, and a protective layer extending longitudinally of the material head to cover the array of heat dot portions. According to the method, the material head is cut along at least one cutting line which extends transversely of the material head at a position between two adjacent heating dot portions, wherein the protective layer has cutouts which extend from the respective longitudinal edges of the protective layer toward the array of heating dot portions at the position of the cutting line.

摘要： A pair of holes are formed with a predetermined space therebetween on a long and narrow base plate. An adhesive is applied to the surface of the base plate. Head substrates each having a row of thermal resistors on the surface thereof are placed on the adhesive on the base plate such that the joint of the head substrates is positioned between the pair of holes of the base plate. The adhesive is hardened in the state in which the head substrates are pushed upward by thrusting means inserted into a pair of holes while the base plate is supported from below and the head substrates is pressed from above. The base plate is bonded to a radiating plate by an adhesive only at the central portion. Thus, there is no difference in level at the joint of the head substrates, and even when the radiating plate expands due to heat, the base plate is not deformed.
