Patent number: 7587971Abstract: A pneumatic cylinder designed to convert compressed air into mechanical output is disclosed. A piston assembly, sealed at both end by caps, contains and guides the motion of a piston assembly. Pressure forces on the piston assembly are transmitted via a mechanical structure that distends via a slot that runs the length of the piston assembly. A flexible steel band, which passes through the piston assembly, seals the slot to minimize air leakage. An air control device, such as a servo valve, is operatively coupled to the piston assembly and travels with the piston assembly when a differential pressure is produced on the piston assembly. This arrangement results in a dynamic relationship between airflow and differential pressure that is conducive to precision force and motion control. In addition, the end caps may include snubbers to diffuse sound waves associated with air moving in the piston assembly of the pneumatic cylinder.Type: GrantFiled: March 21, 2005Date of Patent: September 15, 2009Assignee: Sunstream ScientificInventor: Michael K.

Patent number: 7568423Abstract: Repulsive magnetic forces in the axial direction of cylinder tubes act between the rows 11 of inner magnets of pistons 10, 10 accommodated in two cylinder tubes 2, 2, and the inner magnets 12 of the pistons 10 come to a halt being slightly deviated relative to the outer magnets 22 in the axial direction of the tube. Due to this deviation, a magnetic holding force Fc is produced between the inner and outer magnets 12, 22. Since the magnetic holding force Fc is produced in a static state, a smooth movement can be attained from a static state suppressing the occurrence of a stick slip phenomenon at the start of movement as compared to the prior art, which does not produce the magnetic holding force in a static state.Type: GrantFiled: March 14, 2005Date of Patent: August 4, 2009Assignees: Howa Machinery, Ltd., Koganei CorporationInventors: Naoki Minowa, Hiroshi Yoshida, Akiyoshi Horikawa, Mitsuo Noda

Patent number: 7493848Abstract: A magnet type rodless cylinder provided with a slide magnetically coupled with a piston arranged in a cylinder tube and a slide able to move outside of the cylinder tube. The slide has a connection mount detachably attached to it. When attaching the connection mount, the position where the connection mount and an end cap strike/contact becomes the striking/contacting position of the piston. When using a rodless cylinder without a connection mount, the distance between the slide and an end cap when the piston is positioned at the striking/contacting position becomes longer than the striking/contacting distance due to the removal of the connection mount. Therefore, external dampers able to strike/contact the slide are detachably attached to the end caps at the slide sides. Due to this, regardless of the use or nonuse of a connection mount, the piston and slide can always stop at the striking/contacting position.Type: GrantFiled: March 13, 2006Date of Patent: February 24, 2009Assignees: Howa Machinery, Ltd., Koganei CorporationInventors: Akiyoshi Horikawa, Naoki Minowa, Hiroshi Yoshida, Mitsuo Noda, Tsuyoshi Yonezawa

Patent number: 7194949Abstract: A magnet type rodless cylinder comprised of cylinder tube of a double tube structure provided with an outside tube of an elliptical flattened outside circumferential shape and two inside tubes inserted into the outside tube. When pressurized air is supplied alternately to the inside tubes from a port provided at an end cap, two pistons move reciprocatingly inside the inside tubes. Due to this reciprocating motion, this reciprocating motion causes reciprocating motion of a slide magnetically coupled with the two pistons at the outside of the outside tube. The inside pressure caused by the pressurized air acts exclusively on the inside tubes and does not directly act on the outside tube of the flattened outside circumferential shape, so the thickness of the outside tube can be reduced and, even if the cylinder tube is made a double tube structure, the total thickness will not become greater than in the past.Type: GrantFiled: October 28, 2005Date of Patent: March 27, 2007Assignee: Howa Machinery, Ltd.Inventor: Mitsuo Noda

Patent number: 6766204Abstract: This invention relates to establishing alignment or a desired orientational relationship between a master and a slave of a telerobotic system. The invention can advantageously be used in a surgical apparatus. A method of establishing a desired orientational relationship between a hand-held part of a master control and an end effector of an associated slave as viewed in an image displayed on a viewer is provided. The method includes causing the end effector to remain stationary, determining a current orientation of the end effector relative to a viewing end of an image capturing device operatively associated with the viewer and determining a desired corresponding orientation of the hand-held part of the master control relative to the viewer, at which orientation the desired orientational relationship between the hand-held part of the master control and the end effector would be established.Type: GrantFiled: December 28, 2001Date of Patent: July 20, 2004Assignee: Intuitive Surgical, Inc.Inventors: Gunter D. Niemeyer, William C. Nowlin, Gary S. Guthart

Publication number: 20040060434Abstract: A piston rod-less linear drive (1) has a housing (2) with a longitudinal slot (5) having a moving force coupling member extending through it. The outer slot opening (7) is provided with at least one covering band (33), which is fixed at an attachment section (34) on a longitudinal side (37) of the outer slot opening (7). The covering band ( )33) furthermore has a pivoting covering section (35), which is provided with detent means (46), which render possible a releasable detent function in a covering position covering the outer slot opening. Actuating means kinematically coupled with the force coupling member may act on the covering band in order to cause the detent locking action.Type: ApplicationFiled: August 1, 2003Publication date: April 1, 2004Inventors: Rolf Weberruss, Gerhard Krafft, Thomas Wagner
