  • Patent number: 11181854
    Abstract: An image forming apparatus includes a plurality of temperature-influence members, a first-point temperature acquisition unit, a second-point temperature estimation unit, and a controller. The plurality of temperature-influence members have influence on a temperature of a recording medium on which an image is formed. The first-point temperature acquisition unit is configured to detect or estimate a temperature of the recording medium at a first point. The second-point temperature estimation unit is configured to estimate a temperature of the recording medium at a second point, based on a detection result of at least one of a temperature of the recording medium at a point different from the second point and a temperature of a member or atmosphere. The controller is configured to control the plurality of temperature-influence members, based on an acquisition result from the first-point temperature acquisition unit and an estimation result from the second-point temperature estimation unit.

  • Patent number: 6127765
    Abstract: A micro-electromechanical device, such as a micro-sensor or micromachine, includes a movable part in the form of a cantilever or diaphragm, which is formed on a substrate. In order to recover stiction in which the movable part is fixedly adhered to the substrate, a heating element is provided on a surface of the substrate which is opposed to the movable part. The heating element can be operated upon occurrence of stiction, so as to generate heat and thereby separate the movable part from the substrate and assure a proper operation of the device. The device can be produced at a relatively low cost, and achieves a stiction recovery with a high reliability, even when the device is enclosed in a package.
