Patent number: 8104966Abstract: In a bush (10) which relatively-rotatably supports a journal shaft (1) around its central axis by housing the journal shaft (1) in a formed bearing hole (11), the bush 10 includes an oil supply groove (16) formed spirally to supply lube oil to an inner surface of the bearing hole (11) which contacts to the journal shaft (1) when the journal shaft relatively rotates. A ratio of an area of the oil supply groove (16) to the inner surface area of the bearing hole (11) is equal to or less than 30%. A product of a distance in the central axis direction and a distance in the circumferential direction of the journal shaft (1) between the oil supply groove (16) in next to each other on the inner surface of the bearing hole (11) is within 50 to 300 mm2 range.Type: GrantFiled: May 10, 2007Date of Patent: January 31, 2012Assignee: Komatsu Ltd.Inventors: Hiroshi Yamamoto, Motohide Sugihara, Atsushi Nagato

Patent number: 6693790Abstract: Insulative viscous fluid or gel material having low hardness is used for at least a first electricity insulating layer as an insulating layer of a static electricity chuck. Since a holding surface of the first electricity insulating layer is deformed in accordance with a back surface shape of a wafer, a substantially entire surface of the holding surface comes into intimate contact with the wafer uniformly. An exposing surface of the electricity insulating layer may be coated with a second electricity insulating layer having corrosion resistance. With this structure, adhesion between the back surface of the wafer and the static electricity chuck apparatus is enhanced, which reduces the contact thermal resistance, and it is possible to obtain a static electricity chuck apparatus which is capable of controlling temperature of a surface of the wafer with high precision and has high plasma resistance and durability.Type: GrantFiled: April 12, 2002Date of Patent: February 17, 2004Assignee: Komatsu, Ltd.Inventors: Teruyuki Matsuki, Motohide Sugihara, Kanichi Kadotani
