  • Publication number: 20190359032
    Abstract: A radiant heater device has an electrode embedded in a substrate part and a plurality of heating parts. The electrodes are formed by material that has low specific resistance. An area occupied by the electrode is restricted. The heating parts are formed by material having high specific resistance in order to generate heat so that radiation is produced. The electrode and the heating part are electrically connected within the substrate part. The plurality of heating parts are arranged in parallel between a pair of electrodes. The electrodes and the heating parts are formed in a film-like shape, and the thermal capacity is reduced. As a result, a temperature of the heating parts rises promptly in response to a turning on of power. In addition, the temperature of the heating parts promptly decreases when an object comes into contact therewith.

  • Patent number: 10339602
    Abstract: A first estimator estimates first power to be generated by a photovoltaic power generation apparatus during an interested period. A second estimator estimates second power to be consumed by an electric load during the interested period. A power purchasing cost calculator calculates, when there is a shortfall in the first power compared to the second power, a cost to be paid for receiving, from a power grid, power for compensating for the shortfall. A determiner compares an amount of money to be paid to a customer facility in accordance with a trading term when power is supplied from the power storage apparatus to the power grid, with the cost calculated by the power purchasing cost calculator. A controller causes the power storage apparatus to the electric load when the cost to be paid to the customer facility is equal to or less than the cost.

  • Patent number: 4630131
    Abstract: A recording signal generation system for a color video signal which is suitable for high density recording in a magnetic recording and playback apparatus. In each horizontal scan period which includes an effective horizontal scan period and a horizontal blanking period arranged serially on the time axis, a luminance signal is positioned in the effective horizontal scan period while, in the horizontal blanking period, compressed color signals generated by time-axis compressing color signals having a duration equal to the effective horizontal scan period by a predetermined ratio are disposed. The luminance signal and compressed color signals are time-division multiplexed. Special burst pilot signals are superposed on the multiplex signal each of which is separable from the compressed color signals and alternate with the other at an interval of one horizontal scan period, thereby discriminating the color signals from each other while indicating a position of horizontal blanking period.
