  • Publication number: 20070062349
    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: 7144106
    Abstract: To prevent cockling occurring in a fixed material in a liquid fixing apparatus more effectively and make a paper gap small thereby to improve print quality. On a fixed material transporting surface, a through hole corresponding to a sucking hole is formed, further a recess functioning as a suction chamber is formed, and a through hole is formed in this recess. When intake is performed by the suction unit, and a fixed material is transported on a fixed material transporting surface, the fixed material is sucked and supported on the transporting surface. Sequentially, when the fixed material is fixed, cockling of the fixed material is sucked into the recess by the sucking hole of the suction chamber that is the recess, so that paper rising is prevented.

  • Publication number: 20060250473
    Abstract: A fixed material transportation surface of the fixed material transportation apparatus is formed inclining so as to become higher toward a downstream side from an upstream side of transportation direction of the fixed material, and is transported while sucking the fixed material supplied on the fixed material transportation surface. Thus, since the cockling is drawn when the fixed material is transported while being raised to transportation direction on the fixed material transportation surface even if cockling extending to transportation direction generates on the fixed material after fixing, growth of the cockling can be prevented.

  • Patent number: 7093931
    Abstract: The present invention involves a sucking device having a fixed material transportation surface including plural sucking holes, a decompression chamber connecting to the plural sucking holes, and a sucking device sucking air in the decompression chamber. 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 fixed by a fixing head at the state of being stuck and is transported gradually to a downstream side by the delivering device on the fixed material transportation surface. When fixing is finished, the fixed material separates from the surface of the fixed material transportation surface and rises slightly by blowing air from the sucking holes by a blowing device so as to move to a discharging direction.

  • Publication number: 20060068110
    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: 6991328
    Abstract: A follower roller is brought into press contact with a driving roller by a load having a predetermined value, thereby being rotated in accordance with a rotation of the driving roller to transport the medium clamped therebetween in a first direction. The follower roller includes a shaft portion and a roller body provided so as to surround the shaft portion. The follower roller is configured such that a value of a ratio f/F is not greater than 0.03. Here, F is a force transporting the medium in the first direction which is generated by the load, and f is a resistance force generated in a second direction opposite to the first direction by a friction loss of the shaft portion of the follower roller which is generated by the load.
