Patent number: 7566845Abstract: In an overheat protection circuit for power supply devices in the present invention, overheat protection is provided by using a Schottky barrier diode (SBD) in place of a dedicated thermosensor. The overheat protection circuit is designed to flow reverse leakage current Ir resulting from temperatures of the SBD thermally coupled with a rectifier diode to a photocoupler inside an output-voltage detecting circuit in a direct-current power supply device. Thereby, where the reverse leakage current of the SBD is increased (where temperatures of the rectifier diode are elevated due to overload), a feedback signal of the output-voltage detecting circuit is increased to decrease the output voltage, thereby the direct-current power supply device is protected from overheat.Type: GrantFiled: December 19, 2006Date of Patent: July 28, 2009Assignee: Sanken Electric Co., Ltd.Inventors: Hiroshi Usui, Yoichi Kyono

Patent number: 7560669Abstract: A method of thermal treatment of components. The optimum thermal amplitude of the components at which the phase transformation kinetics of the components is maximum is determined by subjecting samples of the components to cyclic thermal processing at various thermal amplitudes by maintaining the upper temperature constant and varying the lower temperature. A thermal amplitude which is higher than the optimum thermal amplitude is selected. The components are subjected to cyclic thermal processing at the thermal amplitude selected above to achieve near uniform phase transformation kinetics of the components across their crosssection. The components are cooled down to room temperature to obtain components with near uniform microstructure and properties.Type: GrantFiled: December 6, 2006Date of Patent: July 14, 2009Assignee: Tata Consulting Services Ltd.Inventors: Satyam Suraj Sahay, Karthik Krishnan

Patent number: 7549566Abstract: A heating characteristic value at any measuring point of an object at any measuring location of a heating furnace is determined as a single invariable by using temperature (Tint and Ts) measured at the measuring point of the object and heating temperature (Ta) and heating time (t) at the measuring location of the heating furnace. The heating characteristic value (m-value) may be calculated without using physical characteristics of the object. By using the m-value, a temperature profile of the object heated under a modified heating condition may be simulated in a short period of time without actually heating and measuring the temperature of the object at a high accuracy level. By using such a simulation, an appropriate heating condition for heating an object in accordance with a desired heating condition may easily be determined.Type: GrantFiled: July 30, 2003Date of Patent: June 23, 2009Assignee: Panasonic CorporationInventors: Masaru Nonomura, Yoshinori Isobata, Hiroaki Onishi, Masahiro Taniguchi

Publication number: 20090150057Abstract: A heating module for an oxygen sensor comprises an estimated mass module, a cumulative mass module, and a temperature control module. The estimated mass module determines an estimated mass of intake air to remove condensation from an exhaust system after startup of an engine. The cumulative mass module determines a cumulative mass of intake air after the engine startup. The temperature control module adjusts a temperature of an oxygen sensor measuring oxygen in the exhaust system to a first predetermined temperature after the engine startup and adjusts the temperature to a second predetermined temperature when the cumulative air mass is greater than the estimated air mass, wherein the second predetermined temperature is greater than the first predetermined temperature.Type: ApplicationFiled: June 4, 2008Publication date: June 11, 2009Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: Justin F.

Publication number: 20090139982Abstract: Fuser heater element damage due to excessive heating power is prevented by estimating available power supply heating power for proper power control. The estimate is performed by applying a predefined portion of the heating power available from the power supply to the heater element. The predefined portion is determined so that the heater element will not be damaged even if the power supply is at the maximum voltage level of any power supply that may be encountered. The temperature of the heater element is measured, and, if below a predefined temperature, a heating power estimate is made. If not, the heater element is heated by applying power in accordance with a stored heating power estimate from the last heating power estimate. A heating power estimate is made each time the heating element is heated from a temperature below the predefined temperature.Type: ApplicationFiled: November 29, 2007Publication date: June 4, 2009Inventors: Jichang Cao, James Douglas Gilmore, Calvin Dale Murphy
