The inner surface of the outer tube is absorptive to radiant energy, and the outer surface of the outer tube is emissive to radiant energy so that radiant energy from the heating element passing through the inner tube is absorbed and re-emitted from by outer tube.Type: GrantFiled: April 30, 1997Date of Patent: June 22, 1999Assignee: Hill-Rom, Inc.Inventors: John Stephen Campbell, Charles Goldberg

Patent number: 5907663Abstract: Disclosed is a far-infrared electric heater mainly including an electric heating coil, an inner element set in the heating coil, and an outer tubular member enclosing and insulating the heating coil and the inner element. The inner element is made by mixing and sintering quartz and far-infrared optical material. Continuous teeth are provided on outer surface of the inner element and/or inner surface of the outer tubular member to increase surface area for enhancing the reflection of the radiant far-infrared rays, so that an object can be heated by the electric heater in a highly efficient manner.Type: GrantFiled: June 24, 1998Date of Patent: May 25, 1999Inventor: Wen-Ching Lee

Patent number: 5898816Abstract: The invention concerns the ageing of material samples in the test enclosure f an apparatus for testing exposure to light and weathering, using visible light, UV light and medium- or long-wavelength IR radiation and with air circulation. In order to ensure reproducible test results, a value representing the surface temperature of the sample is measured by means of a temperature sensor and compared, at the input of a control unit, with a predefined reference temperature. In the event of a temperature difference, a control signal generated by the control unit adjusts the power supply to a separate IR radiant heater for medium- and long-wavelength IR radiation in such a way that the difference disappears in accordance with a predefined indicial response.Type: GrantFiled: January 19, 1998Date of Patent: April 27, 1999Assignee: Xenotest Gesellschaft fur die Herstellung von Materialprufgeraten mbHInventors: Roland Heeger, Arthur Schonlein, Bernd Rudolph, Peter March

Patent number: 5795396Abstract: An apparatus for forming a deposited film which includes a film forming chamber, with a means to evacuate the inside of the chamber. A substrate holder for holding a substrate is located in the chamber. Starting material gas is supplied to the chamber to enable film formation. A light energy source is also provided to irradiate the substrate in order to heat its surface. The strength of the light energy is controlled to provide a non-uniform temperature distribution pattern on the substrate.Type: GrantFiled: June 25, 1996Date of Patent: August 18, 1998Assignee: Canon Kabushiki KaishaInventors: Shunichi Ishihara, Jun-ichi Hanna

Patent number: 5783025Abstract: Semiconductor die attach occurs by bonding the semiconductor die to a support member such as a lead frame. An optical heat source provides heat for bonding the die attach material. An exhaust system removes vapors from the die attach material during bonding. A tungsten halogen lamp is an exemplary optical heat source. An air amplifier is exemplary to provide exhaust pressure. An exhaust manifold having a plurality of screens spreads the exhaust pressure over the width of the lead frame. A gas shower disposed over the lead frame aids in removing vapors.Type: GrantFiled: November 6, 1996Date of Patent: July 21, 1998Assignee: Texas Instruments IncorporatedInventors: Ming Hwang, Leslie E. Stark, Gonzalo Amador

Patent number: 5487127Abstract: A rapid thermal heating apparatus in which lamps are disposed in a plurality of light pipes arranged to illuminate and supply heat to a substrate. The light pipes are positioned so that the illumination patterns overlap. The energy supplied to the lamps is controlled to provide a predetermined heating pattern to the substrate. A liquid cooled window cooperates with the light pipes to transmit energy to a wafer disposed in an evacuated chamber.Type: GrantFiled: October 5, 1993Date of Patent: January 23, 1996Assignee: Applied Materials, Inc.Inventors: Christian M. Gronet, James F. Gibbons

Patent number: 5459327Abstract: A far-infrared radiator includes carbon fiber mixed paper and an organic compound layer laminated on both sides of the carbon fiber mixed paper. The far-infrared rays are radiated from the front surface and the back surface of the carbon fiber mixed paper by applying current to the carbon fiber mixed paper. The far-infrared rays radiated from the carbon fiber mixed paper cause resonance at a particular wavelength in the organic compound layer and the far-infrared rays in a wavelength range which depends on that wavelength are radiated. The wavelength range of the radiated far-infrared rays can be controlled by selecting the materials for the organic compound layer.Type: GrantFiled: March 18, 1994Date of Patent: October 17, 1995Assignee: Kabushiki Kaisha Dairin ShojiInventor: Harehiko Nomura
