  • Publication number: 20240103414
    Abstract: A fixing unit or device that can be used in an image forming apparatus includes a first heater element that is formed of a material that increases in electrical resistance with increases in temperature. A controller of the fixing unit is configured to vary a duty ratio of electric power applied to the first heater element during a start-up operation in which the temperature of the first heater element is raised to a target operating temperature. By varying the duty ratio during the start-up operation, changes in the resistance of the first heater element with the heating can be compensated. For example, the duty ratio can be increased during the course of the start-up to achieve the target operating temperature faster.

  • Patent number: 6235981
    Abstract: A p-type thermoelectric converting substance used as a p-type semiconductor in a thermoelectric converting module consisting essentially of a substance expressed by a chemical formula CoSbxSny or CoSbxGey (2.7<x<3.4, 0<y<0.4, x+y>3), and containing a small amount of oxygen z defined by 2(x+y−3)≧z. The amount of oxygen z is preferably limited such that it is not higher than 0.1 molecules per 1 molecule of Co. An alloy ingot consisting essentially of CoSbxSny or CoSbxGey (2.7<x<3.4, 0<y<0.4, x+y>3) is ground to obtain a raw material powder. Then, the powder is cast into a mold, and the mold is sintered under a non-oxidizing or reducing atmosphere. The thus obtained substance reveals p-conductivity in a stable manner over a wide temperature range, and has excellent thermoelectric converting properties.
