  • Patent number: 7971953
    Abstract: A recording-medium-residual-quantity detecting device includes a first rotation-quantity detecting unit that detects a rotation quantity of a roll in which a recording medium is wound. A second rotation-quantity detecting unit detects a rotation quantity of a transportation roller that transports the recording medium by rotating in contact with the recording medium that is unwound from the roll. A controlling unit has a winding control mode in which driving units of the device are controlled so that rotational powers to wind the recording medium into the roll without slack between the roll and the transportation roller are applied to the roll and the transportation roller. The residual quantity of the recording medium is calculated on the basis of a rotation quantity ?r of the roll and a rotation quantity ?s of the transportation roller that are respectively detected by the rotation-quantity detecting units when the winding control mode is executed.

  • Publication number: 20110033626
    Abstract: Resist coating treatments for application of a resist solution to removal of a resist film on a wafer edge portion. A laser irradiation unit applies a laser light in a resist coating unit. At the time of resist coating treatment, the resist solution is discharged onto a central portion of the rotated wafer from a resist solution supply nozzle to form a resist film on the wafer. Thereafter, the laser irradiation unit moves to an outer peripheral portion of the wafer and applies the laser light onto the resist film on the outer peripheral portion to dry the resist film on the outer peripheral portion. The application of laser light is continued, and the solvent supply nozzle moves to a position above the edge portion and supplies solvent to the resist film on the edge portion. The solvent dissolves and removes the resist film on the edge portion.

  • Patent number: 7712402
    Abstract: A food slicer for slicing a food product is provided. The slicer may have an adjustable surface and a stationary surface with a blade interposed therebetween. The food product may be sliced with a specific thickness via the blade by traversing the food product from the adjustable surface to the stationary surface. A trailing edge of the adjustable surface and an edge of the blade may define a gap distance which determines a slicing thickness of the food product. A cam may contact an underside of the adjustable surface to set the gap distance. The gap distance may be reset by rotating the cam. More particularly, the cam may have a plurality of cam surfaces. Each of the cam surfaces may have a different distance to a rotating axis of the cam. The gap distance may be changed by rotating the cam such that a different cam surface contacts the adjustable surface's underside.

  • Patent number: 7530687
    Abstract: Of suction holes formed on a medium transporting surface, the areas of the suction holes formed in positions corresponding to ends of a medium which is being transported are set larger than the areas of other suction holes. Hereby, since large air flow is obtained under the both side ends or the leading end of the medium, the medium is transported in a state where the both side ends or the leading end are attracted into the suction holes, and a stain due to contact with a recording head can be prevented.

  • Patent number: 7479190
    Abstract: In the present invention, a plurality of solvent supply nozzles for solvents having different solubility parameters are provided in a coating treatment apparatus. For a solvent supply nozzle for use at the time of edge rinse, a solvent supply nozzle is selected that discharges a removal solvent having a solubility parameter different by a set value or more from that of a coating solvent contained in a coating solution. During coating treatment, the coating solution is discharged from a coating solution supply nozzle onto the central portion of a rotated substrate to form a solution film having a predetermined film thickness. Immediately after the formation, edge rinse is started with the coating solution on the substrate not dry yet, in which the removal solvent is supplied to the peripheral portion of the substrate from the selected solvent supply nozzle.

  • Patent number: 7390085
    Abstract: On a medium transporting surface, a dimple extending continuously from a transportation upstream end of a medium to a transportation downstream end are formed. Hereby, a leading end of the medium, after pulled into the dimples once, is transported in the pulled state. Therefore, it is prevented that the leading end of the medium is curled up by a conventional partition wall provided in the direction perpendicular to the medium transporting direction, so that it is possible to prevent a stain on the medium caused by contact with a recording head.

  • Patent number: 7367668
    Abstract: A fixed material transportation apparatus having a reciprocating stage, plural sucking holes, a decompression chamber connecting to the plural sucking holes, and a sucking device sucking air in the decompression chamber set at a discharging side of the fixed material. The fixed material is fed on the fixed material transportation surface of the sucking device by the delivering device, and is stuck on the fixed material transportation surface through the sucking holes by the sucking device. The fixed material is transported gradually to a downstream side from an upstream side by the delivering device on the fixed material transportation surface. The fixed material then separates from a surface of the fixed material transportation surface and rises slightly by blowing air from the sucking holes so as to move to discharging direction, that is, the downstream side.
