Cylindrical Or Roller-type Support For Material To Be Heated Patents (Class 219/469)
  • Patent number: 10562224
    Abstract: The present invention discloses a heat-resistant glue roll structure with discharge through holes, which comprises a shaft sleeved with a high-temperature resistance insulation layer on the surface thereof. Multiple discharge through holes are formed on the high-temperature resistance insulation layer and communicate the outer and inner surface of the high-temperature resistant insulation layer. A heat-resistant soft glue outer layer is also sleeved on the surface of the high-temperature resistant insulation layer. Since the high-temperature resistant insulation layer is provided with the discharge through holes in the present invention, air bubbles generated both between the high-temperature resistant insulation layer and the heat-resistant soft glue outer layer and between the high-temperature resistant insulation layer and the shaft would be squeezed to move towards the discharge through holes and discharged therefrom.

  • Patent number: 10481533
    Abstract: A fixing device includes a fixing member, a temperature measurement sensor, a movement mechanism, a movement time calculation section, a movement position calculation section, and a temperature control section. The movement mechanism moves the temperature measurement sensor to scan non-heated regions and a heated region along a width direction of the fixing member. The movement time calculation section obtains an arrival time on the basis of a temperature change measured by the temperature measurement sensor due to movement of the temperature measurement sensor. The movement position calculation section calculates the movement position on the basis of a ratio of a second movement time to a first movement time. The temperature control section performs temperature control on the fixing member on the basis of the movement position calculated by the movement position calculation section, and the temperature measured by the temperature measurement sensor.

  • Patent number: 10156204
    Abstract: An improvement to a free-piston Stirling machine having a cylinder mounted within a housing. The cylinder has a flange for mounting the cylinder within the housing to a transition plate with a central opening for receiving the cylinder. An elastic rim bounds and surrounds the opening and extends in an axial direction from the plate to a crest of the rim. The crest of the rim is in contact against a first axially facing side of the cylinder flange. The interior side of the rim is outwardly spaced from the exterior side of the cylinder. A compliant clamp is attached to the transition plate and is positioned on the opposite, axially facing side of the cylinder flange. The compliant clamp has an elastic spring extending against the cylinder flange which applies a force urging the cylinder flange in an axial direction against the crest of the elastic rim.

  • Patent number: 7504605
    Abstract: The heating apparatus of a surface-heating type, includes a rotary member, an opposing member that forms a nip with respect to the rotary member, and a heating member for heating a portion of a rotary member surface other than the nip, in which temperature used for heating the rotary member by the heating member is controlled, and a heating material inserted in the nip to be nipped and conveyed therein is heated using heat of the rotary member. Accordingly, after insertion of the heating material in the nip starts, control temperature of the heating member is increased before the rotary member rotates by one revolution, thereby preventing an uneven heating phenomenon of the heating material in the first revolution and the second revolution or later, and preventing uneven gloss due to the uneven heating phenomenon in the fixing apparatus.

  • Patent number: 7491911
    Abstract: A MEMS vapour bubble generator that uses a heater in thermal contact with a liquid to generate a bubble. The heater is energized by an electrical pulse that is shaped to have a relatively low power, sub-nucleating portion and a high power portion that nucleates the bubble. The thermal energy transferred to the liquid by the sub-nucleating portion speeds up the nucleation of the bubble across the surface of the heater during the nucleating portion. This produces larger, more stable bubble having a regular shape.

  • Patent number: 7446281
    Abstract: A fusing device (23) has heat reflectors (238) and (239) positioned in consideration of the fact that convective heat loss from respective outer surfaces of the heat reflectors (238) and (239) depends on orientation of the outer surfaces. More specifically, each of the heat reflectors (238) and (239) are positioned so as to have a convective heat transfer coefficient ? of up to 0.9. The convective heat transfer coefficient ? is given by the following expression: ?=(Su+0.77Sh+0.54Sd)/(Su+Sh+Sd), were Su is a projected area of an outer surface of each of the heat reflectors on an upper horizontal plane, Sh is a projected area of the same on a vertical plane, and Sd is a projected area of the same on a lower horizontal plane.
