Patent number: 7157676Abstract: A device (10) for thermally clamping and releasing tools (11) in shrink-fit chucks (12), having a socket (15) for a shrink-fit chuck (12), a heating unit (16) that can be moved toward and away from the mounted shrink-fit chuck (12), and a cooling unit (20) for cooling the heated shrink-fit chuck (12). The cooling unit (20) has at least one coolant distributor (21, 22) that is capable of moving in relation to the socket (15) with the mountable shrink-fit chuck (12), conveys a preferably fluid coolant, e.g. cooling water, and has outlets (23) for the coolant, which are oriented toward the socket (15) with the mountable shrink-fit chuck (12) and out of which the coolant travels under pressure to act on the outside of the socket (15) with the mountable shrink-fit chuck (12) for cooling purposes (FIG. 1).Type: GrantFiled: March 17, 2005Date of Patent: January 2, 2007Assignee: Bilz Werkzeugfabrik GmbH & Co. KGInventor: Ruediger Steudte

Patent number: 7132632Abstract: A high frequency induction heater built in an injection mold. The high frequency induction heater has a metal or silicon mold-insert, at least a heating module and at least a thermometer detector. The elements are reasonably fit with the mold-insert utilizing well-defined MEMS technology and UV-LIGA process. The high frequency induction heater is employed to apply a local heat for a microstructure of mold-insert during the micro molding process. By using the high frequency induction heater a fluid mold flow and high aspect ratio replication is achieved.Type: GrantFiled: February 25, 2004Date of Patent: November 7, 2006Assignee: U-Tech Media Corp.Inventor: Jung-Tang Huang

Patent number: 6953311Abstract: A tool holding and working piece-clamping assembly has a stand, a driving device, a threaded rod, a rail assembly, a brake post, a working piece-clamping device and a tool holding device. The working piece-clamping device has an upper clamping device slidably connected to the rail assembly and a lower clamping device corresponding to the upper clamping. The working piece-clamping device has a brake electrically connected to a contact switch and slidably mounted on a brake post. The tool holding device is slidably connected to the rail assembly and has a connecting base screwed with the threaded rod. With such an arrangement, only one threaded rod with a driving device is needed to actuate the tool holding device and the working piece-clamping device to operate. Consequently, the consumption of power can be reduced.Type: GrantFiled: August 27, 2003Date of Patent: October 11, 2005Assignee: KSI Technologies Corp.Inventor: Hua-Chang Pang

Patent number: 6878909Abstract: A method of performing regional heating of a system having a substrate. The method may include applying a thin film to the system, and controllably energizing a coil positioned near the thin film. The energized coils thereby generate a magnetic flux. The method further includes inducing a current in the thin film with the magnetic flux thereby heating the system.Type: GrantFiled: February 28, 2003Date of Patent: April 12, 2005Assignee: Board of Control of Michigan Technological UniversityInventors: Paul L. Bergstrom, Melissa L. Trombley

Patent number: 6841763Abstract: A heat induction workstation has a base, a housing, a working station, an electrical power supplier and a cooling device. The housing has two baffles to divide the inner space of the housing into a central chamber and two side chambers. The working station is mounted in the central chamber and has at least one induction heating device. The electrical power supplier and the cooling device are respectively received in the side chambers. The electrical power supplier is electrically connected to the working station to provide electrical power to the working station. The cooling device is connected to the electrical power supplier to reduce the temperature of the electrical power supplier while the electrical power supplier is in operation.Type: GrantFiled: August 27, 2003Date of Patent: January 11, 2005Assignee: KSP Technologies Corp.Inventor: Hua-Chang Pang

Patent number: 6677560Abstract: The invention relates to an apparatus and a method for heating a workpiece of an inductively heatable material, for example a turbine blade. Such a turbine blade consists of a massive blade base and a low-mass blade leaf. To enable the blade base and blade leaf to be heated in a manner appropriate to each an induction coil is provided, which surrounds the blade base and the blade leaf. By suitable choice of the alternating currents which flow through the induction coil and/or through the interposition of a susceptor between turbine blade and induction coil, the blade base and blade leaf can be heated in an appropriate manner.Type: GrantFiled: February 6, 2001Date of Patent: January 13, 2004Assignee: Ald Vacuum Technologies AGInventors: Helmut Eberhardt, Karl-Heinz Grosse, Karl Herchenröther, Jürgen Lemke
