The light-shading film is a porous layer of inorganic pigment powder dispersed in glass matrix. The light-shading film has small apertures at a portion corresponding to the infrared heater. Alternatively, it has a decreased thickness at the portion. In another alternative, a luster film is used in place of the inorganic pigment layer at the portion corresponding to the infrared heater.Type: GrantFiled: June 12, 2002Date of Patent: December 9, 2003Assignee: Nippon Electric Glass Co., Ltd.Inventors: Takeshi Nagata, Narutoshi Shimatani, Shingo Nakane, Naohide Yamada

Patent number: 5994681Abstract: A method and apparatus has a body of graphite and a magnetic field source operatively connected with the body of graphite so that a magnetic field of the magnetic field source penetrates at least a portion of a surface of the body of graphite. The portion of the surface is crystalline graphite. At least one of the magnetic field source and the body of graphite is movable relative to the other for movement of the at least one of the magnetic field source and the body of graphite relative to the other to cause the magnetic field in the surface portion of the body of graphite to vary to induce eddy currents in the body of graphite and heat the body of graphite.Type: GrantFiled: February 4, 1998Date of Patent: November 30, 1999Assignee: Larkden Pty. LimitedInventor: Robert Lloyd

Patent number: 5973303Abstract: An induction cooktop is formed of a light construction of a stone surface. The surface of the induction cooktop can also be used as a robust work surface top. The cooktop includes a uniformly flat, sufficiently thin stone plate (1) being laid on an equally flat, reinforcement plate (2) for mechanical stability. Induction coils (3 or 3a) are positioned in or under the reinforcement plate for inductive heating of the cooking pots. This arrangement is additionally stabilized through a frame (4) and a substructure (7) and is closed off at the edge through a border or a trim (8) or embedded in a work surface top (6) surrounding the cooktop.Type: GrantFiled: August 17, 1998Date of Patent: October 26, 1999Inventor: Kolja Kuse
