Patent number: 5525780Abstract: A multipurpose chuck apparatus (100) has a chamber (112) for holding a medium (114). The medium (114) is heated into a high temperature molten state by a radio frequency induction heating coil (130). The medium (114) heats up a semiconductor material (118) through a chuck member (116) that separates the medium (114) from the semiconductor material (118). The heating performed by the radio frequency induction heating coil (130) generates a fluid flow within the medium (114), providing a uniform temperature distribution throughout the medium (114). A magnetic rotation device (121) controls movement of rotating member (128) having a mixing member (122) and rotating fins (184) to ensure complete uniform temperature distribution throughout the medium (114), especially in the vicinity of the chuck member (116). An inlet cooling tube (122) and an outlet cooling tube (124), isolated from the medium (114) provide cooling fluid to the chuck member (116) for temperature control of the semiconductor material (118).Type: GrantFiled: August 31, 1993Date of Patent: June 11, 1996Assignee: Texas Instruments IncorporatedInventor: Mehrdad M. Moslehi

Patent number: 5517004Abstract: A method for removing one or more contaminations from a bulk material, the bulk material being fed into a treating chamber (1), exposed therein to a temperature treatment and then discharged. According to the invention, the bulk material is exposed to a vacuum treatment during temperature treatment. An apparatus according to the invention for the implementation of the method comprises a treating chamber (1) for treating contaminated bulk material therein, feeding means (2) for feeding the bulk material to the treating chamber (1), discharging means (9) for discharging the bulk material from the treating chamber and heating means (19) for heating the bulk material in the treating chamber. The apparatus also includes a vacuum forming means (16) for forming a vacuum in the treating chamber.Type: GrantFiled: April 22, 1994Date of Patent: May 14, 1996Assignee: Recycling Nederland Holding B.V.Inventor: Dirk J. Blonk

Patent number: 5401938Abstract: A drop former includes an outer rotary steel body having circumferentially spaced openings which successively reach a lower discharge position to enable viscous material to drop onto a cooling conveyor from within the outer body. An inner steel body, which can be stationary or rotating, is situated within the outer body to direct viscous material to the openings as the openings reach the discharge portion. An electrical inductive heating coil is situated adjacent one or both of the bodies to inductively heat the body, avoiding excessive heating of the viscous material.Type: GrantFiled: November 24, 1993Date of Patent: March 28, 1995Assignee: Santrade Ltd.Inventors: Reinhard Froeschke, Stefan Gehrmann

Patent number: 5360963Abstract: An induction-hardening machine for the contour hardening of cross-axis, intersecting-axis and nonintersecting-axis gears such as hypoid gears includes a programmable logic control unit, a source of quench liquid and a high-frequency induction generator which are operably connected to a high-frequency induction coil which, in one embodiment, is disposed at an inclined angle above the horizontally disposed workpiece (hypoid gear). Fluid connections are made between the source of quench liquid and the induction coil for the rapid delivery of quench liquid. The support platform for the hypoid gear is connected to a rotary drive motor and with the hypoid gear rotating at approximately 900 to 1800 RPM the induction coil is energized with four low energy pulses of relatively short duration. The final heating step is a high energy pulse followed immediately by the quenching step.Type: GrantFiled: February 8, 1993Date of Patent: November 1, 1994Assignee: Contour Hardening, Inc.Inventors: John M. Storm, Michael R. Chaplin
