Patent number: 11715940Abstract: A circular cutting unit for partially cutting one or more layers of a cable or wire along a cutting plane. The circular cutting unit include a knife head including a drive disc and an adjustment disc that are each rotatable about a disc axis. A pair of knife holders that each include a knife blade are pivotally mounted to the drive disc. Relative rotation of the adjustment disc relative to the drive disc causes the knife holders to pivot causing movement of the knife blades toward or away from each other. The circular cutting unit includes a primary drive assembly and an adjustment drive assembly that are each separately operable. The primary drive assembly rotates the knife head at the cutting speed and the adjustment drive assembly rotates the adjustment disc relative to the drive disc.Type: GrantFiled: June 8, 2021Date of Patent: August 1, 2023Assignee: Komax Holding AGInventors: Michael A. Kirst, Richard Schwartz, Dieter Vischer

Patent number: 7159751Abstract: The bondhead of a Wire Bonder, that serves to produce a wire connection between two connection points by means of a capillary guiding a wire, is formed as a pantograph mechanism. The pantograph mechanism comprises a first swivel arm driven by a first motor, a second swivel arm driven by a second motor and two connecting arms. With this pantograph mechanism, the movement of the capillary takes place by means of rotary movements.Type: GrantFiled: May 25, 2004Date of Patent: January 9, 2007Assignee: ESEC Trading SAInventor: Dieter Vischer

Patent number: 7120995Abstract: An apparatus for mounting semiconductors contains a bonding station, whereby the bonding station comprises a wafer table for presenting the semiconductor chips, a substrate table and a pick and place system with a bondhead with a chip gripper. Part of the wafer table is located underneath the substrate table. The pick and place system has a first linear motor that comprises a rigidly arranged stator and a shuttle that can be moved in a first direction guided by first guide elements, and a second linear motor that comprises a rigidly arranged stator and a shuttle that can be moved in a second direction. The shuttle of the first linear motor has second guide elements that guide the shuttle of the second linear motor. The bondhead with the chip gripper is arranged on the shuttle of the second linear motor.Type: GrantFiled: June 3, 2004Date of Patent: October 17, 2006Assignee: ESEC Trading SAInventor: Dieter Vischer

Patent number: 5565861Abstract: Multidigit counting wheel mechanism for a volume-measuring instrument. An absolute encoder for a measuring instrument includes a mechanical counting wheel mechanism consisting of five sensors, mounted in a plane perpendicular to a counting mechanism axle, for each counting wheel and a code, producing a digital rotary angle signal with a resolution of 12.degree., on each counting wheel, with the counting wheel mechanism being visually readable in a conventional manner, with the encoder not increasing the torque required for driving the counting mechanism.Type: GrantFiled: December 6, 1994Date of Patent: October 15, 1996Assignee: GWF Gas-und Wassermesserfabrik AGInventors: Roland Mettler, Dieter Vischer
