Title: Thermal fixing device and image forming device
Inventor: IWAKI HIROSHI
IPC: H05B3/14
Filed: 1992-05-14
Abstract: PURPOSE:To rapidly raise the fixing temperature to a prescribed temperature, and to attain the self-keeping of the prescribed temperature by restricting the supply of electric power to a heating element based on a change in a resistance value when the arriving at the prescribed temperature is attained. CONSTITUTION:A heating roller 5a has the resistance characteristic of positive temperature dependency, and is composed of a cylindrical heating element 10 whose resistance value is rapidly increased when a temperature is risen to the temperature enough to fix toner, for instance, 180 deg.C, and first and second electrodes 11 and 12 formed on the outer and inner peripheries respectively, so as to apply an electric current in the direction of the thickness of the heating element 10. And the outer circumferential surface of the first electrode 11 in contact with a fixed recording paper is properly coated with an offset preventing film consisting of fluorine-based resin. The resistance value of the heating roller 5a itself using the temperature dependency, is rapidly increased to automatically regulate the quantity of the current when the temperature reaches a sufficient specific one at the time of fixing the toner. At this time, rapid change (increase) of the resistance value means the increase that the quantity of current is almost self-regulated by the change in the resistance value.

IPC: H05K5/06
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To miniaturize an enclosure and reduce weight and also reduce costs by mounting a dew-forming member consisting of a material with a high thermal conductivity that is exposed externally to a closed box, and incorporating an evaporation member for receiving dew-forming water being generated at the reverse side of the dew-generating member. SOLUTION: An enclosure 1 for accommodating an electronic equipment has an enclosure body, a door body 3, a dew-generating member 4, an evaporation member 5, and a dew-guiding member 6 and is formed by a closed box consisting of a metallic material. The dew-generating member 4 is mounted to the surface of the door body via a packing 8 for preventing water and insulating heat while being exposed externally, so that the opening of a through window 3a is covered. The dew-generating member 4 is formed by a metallic plate that is made of aluminum alloy as a material with a thermal conductivity higher than that of the material of the enclosure 1. The evaporation member 5 is arranged in an enclosure body for receiving dew-forming water (a) generated at the dew-forming generation member 4.  An inclination surface 6a with a downward inclination from the dew-generating member 4 towards the evaporation member 5 is formed at the dew-forming water guiding member 6, thus miniaturizing a closed box, reducing its weight, and reducing costs.

Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To clamp tool holder tapers of different sizes to a same spindle by allowing a ball at a first bush to clamp a taper of a large size, and allowing a ball at a second bush to clamp a taper of a small size. SOLUTION: A tool holder taper 10 is clamped to a spindle shaft 6. A first bush 20 is pulled rearward by the force of a spring 19 at a pull shaft 16.
