Katsumi Ootsuki has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6290056
    Abstract: A conveying apparatus capable for conveying a magnetic workpiece at high speed with low vibration and low noise, superior in durability, and capable of achieving a reduction in driving force. The conveying apparatus includes a non-magnetic rail having a guide surface for slidably guiding a first surface of a workpiece, a non-magnetic belt having a conveying surface in contact with a second surface of the workpiece and movable along the rail, driving means for running the non-magnetic belt in circulation, and a rotatable roller whose peripheral surface is in contact with the surface of the non-magnetic belt opposite to the feeding surface. Provided in the roller is a magnet adapted to generate a magnetic force having a component force for causing the second surface of the workpiece to be attracted to the roller through the intermediation of the non-magnetic belt and a component force for bringing the first surface of the workpiece into contact with the rail.

  • Patent number: 5816385
    Abstract: A conveying device which is capable of conveying a magnetic workpiece at high speed with low vibration and low noise and which makes it possible to perform a highly accurate positioning. The conveying device includes a non-magnetic rail which has a guide surface for slidably guiding a first surface of the workpiece and a non-magnetic conveying belt which has a conveying surface coming into contact with a second surface of the workpiece and which is movable along the rail. The belt is driven to rotate by a driving device. A magnet is arranged at a position opposite to the rail with the belt therebetween and generates a magnetic force having a component force which causes the second surface of the workpiece to be brought into close contact with the belt and a component force which causes the first surface of the workpiece to be brought into contact with the rail.
