Patent number: 8251775Abstract: A shaft motion detection mechanism capable of detecting the displacement of a rotating body in a direction along a rotational axis and the rotation of the rotating body is disclosed. In one embodiment, the invention is a conditioner head capable of detecting the displacement of a polishing disk in a direction along a rotational axis and the rotation of the polishing disk. A shaft rotates around a rotational axis and a cylindrical shaft is attached to the shaft so that the shaft can be displaced along the rotational axis. A first plurality of projections are formed on the surface of the shaft so as to be aligned in a circumferential direction. A second projection is formed around the entire circumference on the surface of the shaft. Proximity sensors arranged around the rotational axis sense the first and second projections to detect displacement and rotation of the rotating body.Type: GrantFiled: August 27, 2009Date of Patent: August 28, 2012Assignee: Applied Materials, Inc.Inventor: Toshikazu Tomita

Patent number: 6915737Abstract: In an ink supply amount control method for a printing press, ink is supplied from the gap between a plurality of ink fountain keys and an ink fountain roller to an ink supply path in accordance with rotation of the ink fountain roller. The swing operation of an ink ductor roller is temporarily stopped. When the swing operation should intermittently be stopped, the operation of the ink fountain key or the ink fountain roller is controlled to control the ink supply amount to the ink ductor roller. Ink in a corrected amount is supplied to a printing plate attached to a plate cylinder through the ink supply path by the swing operation of the ink ductor roller. An ink supply amount control apparatus is also disclosed.Type: GrantFiled: December 15, 2003Date of Patent: July 12, 2005Assignee: Komori CorporationInventors: Masahiro Hirano, Toshikazu Tomita

Patent number: 6912954Abstract: A method and apparatus are disclosed for numerically adjusting the home position of a plurality of ink fountain blades in a printing press. In the printing press, apparatus is provided for adjusting the ink feed amount to be supplied from an ink fountain into an ink fountain roller by adjusting the position of these ink fountain blades, supplying ink to a printing plate through the ink fountain roller, and printing the ink supplied on the printing plate on a printing sheet. The present method and apparatus first position each ink fountain blade at its home position, then set the indication of the position of each ink fountain blade at a predetermined value. Each ink fountain blade is then adjusted by the same amount while observing the indication of the position of each ink fountain blade. Finally, the position of each ink fountain blade as so adjusted is stored as a new home position.Type: GrantFiled: January 10, 2002Date of Patent: July 5, 2005Assignee: Komori CorporationInventor: Toshikazu Tomita

Patent number: 6402404Abstract: A sheet supply control apparatus for a printing press includes a sucker, a memory, a sheet detector, a counter, and a CPU. The sucker supplies sheets to a printing unit one by one with a predetermined supply interval. A count of sheets to be supplied to the printing unit is set in the memory. The sheet detector detects the sheets supplied from the sucker. The counter counts sheets supplied from the sucker after the sheet detector detects a first sheet. The CPU controls supply operation of the sucker, on the basis of the count preset in the memory and the count of the counter, such that the count of sheets supplied from the sucker coincides with the count preset in the memory. A sheet supply control method for a printing press is also disclosed.Type: GrantFiled: March 1, 2000Date of Patent: June 11, 2002Assignee: Komori CorporationInventors: Toshikazu Tomita, Satoru Eguchi
