Abstract: A molten iron refining method having, an auxiliary material, and an oxidizing gas supplied through a top-blowing lance, to a cold iron source and molten pig iron that are contained/fed in a converter-type vessel, and molten iron is subjected to a refining process. A pre-charged cold iron source is charged into the converter-type vessel at an amount not larger than 0.15 times. A furnace-top-added cold iron source that's part or all of the cold iron source and added from a furnace top is fed during the refining process. A burner at a leading end of the top-blowing lance that spray holes through which a fuel and a combustion-supporting gas are ejected. During the refining process, a powdery auxiliary material processed into powder that's part of the auxiliary material is blown in, to pass through a flame formed by the burner.

Abstract: A converter steelmaking method has molten pig iron subjected to dephosphorization process for dephosphorized molten iron, dephosphorized molten iron is subjected to decarburization process for molten steel. For dephosphorization process, a first cold iron source in amount meeting Formula (1) is charged into first converter-type vessel, then undephosphorized molten pig iron is charged and subjected to dephosphorization process. Dephosphorized molten iron is discharged and held in molten metal receiving vessel. After second cold iron source is charged into first converter-type vessel in which dephosphorization process has been performed, the dephosphorized molten iron held in molten metal receiving vessel is charged and subjected to decarburization process. % Ws0?0.1186T?134 (% Ws0?0) . . . (1), where % Ws0: a ratio (%) of first cold iron source to sum of first cold iron source and charge amount of undephosphorized molten pig iron, and T: a temperature (° C.) of undephosphorized molten pig iron.

Abstract: A robot system includes a robot arm, encoders configured to acquire position information of the robot arm, a first control section configured to execute control processing for controlling operation of the robot arm, and a second control section provided independently from the first control section and configured to transmit a position information request signal for requesting the position information to the encoders. The second control section transmits an interrupt signal to the first control section according to the transmission of the position information request signal. The first control section executes the control processing based on the interrupt signal and the position information output from the encoders based on the position information request signal.

Abstract: If an ink amount supplied from an ink tank to an ejection head reaches a predetermined limit value, ink ejection is not permitted. If initialization data are input and the input initialization data are appropriate, a count value of the ink amount is initialized, and the ink ejection is started again. In addition, the initialization data which is input once and determined to be appropriate is determined to be inappropriate thereafter. By doing so, although ink of which the property and state are inappropriate is used for the refilling, since appropriate initialization data may not be input, it is possible to avoid the inappropriate ink from being used for the refilling.

Abstract: An image producing apparatus according to the present invention includes a control unit configured to switch from an operation mode of a face detection automatic exposing/focusing unit to an operation mode of a color detection automatic exposing/focusing unit when a single object region other than a face image is specified by a manipulation of a touch panel during an operation of the face detection automatic exposing/focusing unit, and to switch from the operation mode of the color detection automatic exposing/focusing unit to the operation mode of the face detection automatic exposing/focusing unit when a single face image is specified by a manipulation of the touch panel during an operation of the color detection automatic exposing/focusing unit.

Abstract: A portable electronic apparatus according to the present invention includes a main body with a front part on which a shooting lens is provided, wherein a moving image shooting button and a still image shooting button are provided at a rear part of the main body. A moving image shooting button and a still image shooting button are provided independent from the two aforementioned recording buttons on an upper face of the main body. The moving image shooting button and the still image shooting button provided at the rear part of the main body can be operated independently from the moving image shooting button and the still image shooting button provided on the upper face of the main body.
