Abstract: A coil component includes a base body, and a coil disposed inside the base body and wound into a spiral shape. The coil includes a plurality of coil conductor portions and a plurality of lead-out conductor portions, both the conductor portions being laminated in a first direction. The lead-out conductor portions overlap, when viewed from the first direction, side gap portions given by regions of the base body on the outer side of the coil conductor portions in a radial direction. The base body includes a cavity between two among the coil conductor portions adjacent to each other in the first direction. The cavity includes a first cavity overlapping first one among the lead-out conductor portions in the first direction. The first cavity is present at a position away two or more pitches in the first direction from the first lead-out conductor portion overlapping the first cavity.

Abstract: To hide a difference in call reference mode at a protocol control section from a basic call control section which provides an added service based on a plural call reference mode, a distributing section 21 of a virtual terminal control device 20 determines whether an event (signal) of a call reference correspondence from a basic call control section 10 is connectable or not to a terminal 40 via a protocol control section 30, and delivers the signal to an actual terminal processing section 22 or a virtual terminal processing section 23. In response to receipt of signals from the basic call control section, the protocol control section and the virtual terminal processing section, the actual terminal processing section determines and executes an operation per state while shifting the state, and transfers the signal to the protocol control section and the basic call control section while converting a call reference of the signal.

Abstract: A method and apparatus is provided for stabilizing the molten metal surface in a mold. The invention is used to improve the quality of the casting slab by modifying a controlling parameter according to the detected slab drawing speed and the actual nozzle flowing characteristics calculated by the measured molten metal surface level and the nozzle opening degree.

Abstract: A continuous casting process introduces the factor of rate temperature change for detecting break out in the cast metal. Introduction of rate of temperature change as a parameter representative of the cast metal condition is successful for avoiding the influence of variation of the casting condition, fluctuation of the powder to be introduced between the casting mold wall and the cast metal, casting speed and so forth. For achieving accurate detection of break out of the cast metal by introducing the temperature change factor, casting mold wall temperatures are measured at various measuring points which are circumferentially aligned. Rates of temperature change at each measuring point and average rate of temperature change of all measuring points are derived and compared for making judgement of possible break out when the difference of the rate of temperature change at each measuring point and the average rate of temperature change becomes greater than a predetermined value.

Abstract: A method of heating a molten steel in a tundish for a continuous casting apparatus while the molten steel being introduced and circulated in a roundabout channel of a horizontal channel type induction heater attached to the side wall of the tundish. This relates to the technique in which electric power is applied to the induction heater depending upon the stored amount of the molten steel in the tundish, for instance, the power is increasingly supplied gradually in the case of the pouring at an initial stage, to effectively eliminate the current interference due to the pinching, and compensate the reduction in the temperature accompanied by the molten steel pouring at the time of the continuous casting.

Abstract: Control method for preventing a breakout or/and a crack of the slab of continuous casting equipment. Heat flux waveforms or heat flux values commensurate to extracted heat values at various positions of a mold are measured by means of thin plate type surface heat flux meters (14, 14x, 14y, 14z) provided at various positions on side shell plate (11, 11c) of the mold (10). When an abnormality or a deviation from a target value is detected, pouring rate is changed, scope of supply, brands and the like of mold powder are controlled, or taper value of short sides of the mold is controlled, so that a breakout or/and a crack of the slab is prevented.
