  • Patent number: 10781059
    Abstract: A bag in which a content is put and of which a mouth portion is not sealed, is disposed in a substantially horizontal attitude in a takeoff area. A height direction position of an expected hold part of the bag and a height direction position of a hold member are caused to correspond to each other. The hold member is caused to hold the expected hold part of the bag disposed in the takeoff area in a state where the height direction position of the expected hold part of the bag and the height direction position of the hold member correspond to each other. The hold member is moved to transfer the bag from the takeoff area to a delivery area after the hold member holds the expected hold part of the bag disposed in the takeoff area.

  • Patent number: 6592726
    Abstract: A vacuum arc coating process that can form a hard coating layer excellent in both bonding quality with the substrate and surface roughness, a coating machine for this process, and a revolving cutting tool produced by this process. Vacuum chamber 1 is provided with subchamber 3 that is less evacuatable than coating chamber 2. Arcing-type evaporation source 4 is placed in subchamber 3. A gas such as nitrogen gas is introduced into subchamber 3 from gas-introducing portion 6 when substrate 10 is cleaned before the deposition, so that the gas pressure is kept higher in subchamber 3 than in the vicinity of substrate 10. This condition suppresses the generation of molten particles when the cathode (the evaporating material) of arc evaporation source 4 is melted and ionized, without reducing the sputtering effect. A revolving cutting tool thus obtained has a small magnitude of surface roughness.
