Patent number: 8693854Abstract: A uniform voltage is applied to loads even to other than a multiple of three loads made of heating lamps connected in parallel to each other, without causing any burden on a primary side. The number of loads is divided into a multiple of three and a multiple of two. A three-phase AC voltage is applied to three primary windings, which are connected as a Y-connection or a ?-connection. Secondary windings, which are each magnetically coupled to a primary winding of a plurality of three-phase transformers and have the same number of turns, are connected with the multiple of three loads.Type: GrantFiled: August 26, 2011Date of Patent: April 8, 2014Assignee: Ulvac, Inc.Inventors: Tsuyoshi Yoshimoto, Katsumi Yamane, Tetsuhiro Ohno, Takahiro Mizoguchi

Patent number: 8521013Abstract: A technology to control temperature of a large substrate to be heated. A temperature sensing device is disposed lateral to a region where a radiation heater faces a substrate to be heated inside a heating chamber. A heating device has the heating chamber, the radiation heater, a power-supply device, a substrate-holding device, a control device, and the temperature sensing device. A control program is built into the control device, according to which the power-supply device controls the power applied to the radiation heater to generate heat such that the temperature of the temperature measurement substrate detected by a thermocouple of the temperature sensing device becomes a set temperature. Furthermore, a circulation passage is disposed in close contact with the temperature-sensing device, and with a coolant flowing through the circulation passage, the temperature of the temperature measurement substrate can be cooled from the set temperature to an initial temperature.Type: GrantFiled: July 28, 2011Date of Patent: August 27, 2013Assignee: Ulvac, Inc.Inventors: Tsuyoshi Yoshimoto, Katsumi Yamane, Tetsuhiro Ohno, Takahiro Mizoguchi

Secondary windings, which are each magnetically coupled to a primary winding of a plurality of three-phase transformers and have the same number of turns, are connected with the multiple of three loads. The number of turns of the M-seat primary winding of a Scott transformer is divided into two at a midpoint, to which an end of the T-seat primary winding having a number of turns equal to (?3)/2 times that of the M-seat primary winding, is connected and to which the three-phase AC voltage is applied.Type: ApplicationFiled: August 26, 2011Publication date: February 23, 2012Applicant: ULVAC, INC.Inventors: Tsuyoshi YOSHIMOTO, Katsumi YAMANE, Tetsuhiro OHNO, Takahiro MIZOGUCHI
