    摘要: A manufacturing method for a continuously cast product of steel includes the steps of detecting a position of a crater end of the product by a method for measuring a solidification state of continuously cast product using a sensor arranged so as to be in non-contact with the product, and controlling at least one condition selected from the conditions of the casting speed and the quantity of secondary cooling water based on the detected position of crater end. The method for measuring a solidification state of continuously cast product includes the steps of transmitting transverse waves of burst-like electromagnetic ultrasonic waves, in which at least one selected from frequency, amplitude, and phase is modulated within a pulse width that has a magnitude of 50 to 150% of the maximum time width not exceeding a time of flight for propagating in said product, to said product as a transmitting signal, receiving a signal after said transmitting signal propagates in said product as a receiving signal, and judging the solidification state of said product by performing a correlation operation of said receiving signal by using a reference signal of a waveform that is the same as or similar to said transmitting signal.

    摘要: The method for controlling flow pattern of molten steel in continuous casting, comprises the steps of: (a) continuously casting a molten steel injected through an immersion nozzle; (b) measuring temperatures of a copper plate on longer side of the mold in width direction thereof at plurality of points; (c) detecting a flow pattern of the molten steel in the mold based on the time-sequential variations of temperatures of the copper plate at individual measurement points; and (d) controlling the flow pattern to establish a specified pattern on the basis of the detected result. The temperatures of mold copper plate are measured by plurality of temperature measurement elements buried in the rear face of the mold copper plate for continuous casting. The temperature measurement elements are arranged in a range of from 10 to 135 mm distant from the melt surface in the mold in the slab-drawing direction.

    摘要: A medium circulating apparatus of engine oil, which improves startability and warm up ability of an internal combustion engine, includes a microbubble generator that generates microbubbles and mixes the microbubbles into the circulating engine oil. Further, the medium circulating apparatus includes a medium temperature acquiring unit that acquires a temperature of the engine oil. The microbubbles are generated by the microbubble generator when the temperature of the engine oil is less than or equal to a predetermined value in order to decrease a viscosity, a heat conductivity, and a heat capacity of the engine oil in which the microbubbles are mixed.

    摘要: A digital broadcast receiver capable of reducing time and labor to back-up contents recorded on one recording medium to another recording medium. A digital broadcast receiver extracts the contents recorded, out of order, on a first recording medium by an extracting unit according to the titles or genres recorded in a content list, and automatically rearranges the extracted contents using an arranging unit according to video-recording date-and-hour recorded in the content list, for recording as a content list onto a second recording medium (300).
