  • Patent number: 7805098
    Abstract: The development device of the present invention has a rotating shutter supported rotatably between a supply opening formed on a toner supply device and a receiving opening formed on a developing tank. The rotating shutter has an open section extending in the axial direction of the roller-shaped main section as well as opened in the direction perpendicular to the axial direction thereof, opening and shutting the supply opening in conjunction with attachment and detachment operation of the developing tank. The rotating shutter shuts the supply opening by covering the supply opening with the outer surface of the roller-shaped main section, and opens the supply opening by communicating the supply opening and the receiving opening through the open section. Thus, it is possible to prevent the leakage of toner even after repetitively performing the attachment and detachment operation of the developing tank.

  • Patent number: 7804647
    Abstract: A method for smoothing an annealed surface uses a sub-resolution mask pattern. The method supplies a laser beam having a first wavelength and a mask with a first mask section having apertures with a first dimension and a second mask section with apertures having a second dimension, less than the first dimension. A laser beam having a first energy density is applied to a substrate region, melting a substrate region in response to the first energy density and crystallizing the substrate region. A diffracted laser beam is applied to the substrate region, smoothing the substrate region surface. Applying a diffracted laser beam to the substrate area may include applying a diffracted laser beam having a second energy density, less than the first energy density, to the substrate region.
