摘要： A heat apparatus for an electromagnetic induction heating system comprises a heat roller that comprises magnetic and conductive material. The heating apparatus also comprises a magnetic excitation coil that is positioned around a portion of the periphery of the heat roller. The magnetic excitation coil is configured to generate a magnetic field that extends to the heat roller, to generate an eddy current within the heat roller, and to generate Joule heat within the heat roller. The magnetic excitation coil is configured to generate a smaller magnetic field at the center area of the heat roller than at the side areas of the heat roller.

摘要： A fixing apparatus of the present invention for an electronic induction heating system includes a heat roller and a magnetic excitation coil that generates Joule heat within the heat roller. The fixing apparatus includes a coil positioner that positions the magnetic excitation coil around a portion of a periphery of the heat roller, a fixing roller that fixes toner image on a recording medium, and a belt that contacts a portion of a periphery of the heat roller and the fixing roller to conduct the generated heat from the heat roller to the fixing roller. The coil positioner further has a surface of first curvature substantially identical to a curvature of a periphery of the heat roller at an opposition area, the opposition area being opposite to a contact area where the heat roller makes contact with the belt. The coil positioner is spaced from the belt by a predetermined distance. The coil positioner further has a first extension extending from a first end of the opposition area of the coil positioner and a second extension extending from a second end of the opposition area of the coil positioner. The first extension and the second extension are spaced from the belt distances larger than the predetermined distance.

摘要： A color TV tube apparatus having a horizontal deflection coil for generating a pincushion-shaped horizontal deflection field, which uses a self-convergence method. In such a color TV tube, the horizontal deflection coil is adjusted so that the vertical focus points of the electron beams lie 50 mm or less on the inside and 30 mm or less on the outside of each edge of the effective display screen area along the horizontal axis. The horizontal deflection coil is adjusted with the focusing of an electron beam by a lensing action of an electron gun non-operational.

摘要： A heating apparatus that enables an abnormally high temperature detection section that detects, when a heating element heated by means of electromagnetic induction reaches an abnormally high temperature, this abnormally high temperature, to operate speedily and reliably irrespective of the material and temperature characteristic of the heating element in a low-cost and compact configuration. In this apparatus, thermostat 301 is disposed on the same side as exciting coil 231 with respect to heat generating belt 210 and between winding bundles of a conductor wire of exciting coil 231. This allows coil guide 234 to hold both thermostat 301 and exciting coil 231 and allows these wires and terminals to be concentrated on one location, thus making it possible to reduce the number of parts and assembling man-hours and configure the body of the apparatus in a low-cost and compact configuration. Furthermore, thermostat 301 operates reliably when heat generating belt 210 reaches an abnormally high temperature irrespective of whether the material of heat generating belt 210 is a magnetic member or not and whether the temperature of heat generating belt 210 has exceeded a Curie temperature or not.
