Title: Estimating method for remaining thickness of brick in blast furnace hearth bottom
Inventor: KUBO HIDEHO
IPC: C21B7/24
Filed: 1979-05-23
Abstract: PURPOSE:To estimate the remaining thickness of brick in the hearth bottom of a blast furnace, by measuring the rate of temp. rise in the hearth bottom by discontinuing the feed of coolant for the hearth. CONSTITUTION:When the charge of a coolant for hearth bottom is discontinued temporarily, the rate of temp. rise due to heat regeneration depends upon the remaining thickness of brick in the hearth bottom. Therefore the remaining thickness of brick can be estimated by determining the relation between the remaining thickness of brick and the rate of the temp. rise. For example, a characteristic curve P is obtained by plotting the rate of temp. rise ( deg.C/hr), measured by a thermocouple thermometer when the feed of the coolant for the hearth is discontinued, in relation to respective remaining thickness of brick, e.g., 1.0m, 1.5m, 2.0m, 2.5m, 3.0m. Hereby, the remaining thickness of brick corresponding to the position where the thermocouple thermometer is buried can be estimated using the characteristic curve P.

Filed: 1990-03-15
Abstract: PURPOSE:To cope with misrecognition by providing a selecting circuit which selects and outputs a 1st control signal as a 4th control signal and a control circuit which controls an equipment to be controlled corresponding to the 4th control signal unless a coincidence signal is generated. CONSTITUTION:No coincidence signal is generated normally, the selecting circuit 5 selects and outputs the 1st control signal as the 4th control signal, and a control circuit 6 controls the equipment 7 to be controlled corresponding to the 4th control signal. When a voice recognizing circuit 2 causes misrecognition, a decoder 4 judges the misrecognition and outputs the coincidence signal indicating the misrecognition and then the selecting circuit 5 is switched to select a 3rd control signal corresponding to a word of 2nd similarity in last recognition, thereby performing control corresponding to the word of the 2nd similarity for the equipment 7 to be controlled. Consequently, the control corresponding to the word of the 2nd similarity can be performed with a voice without pressing a switch and the misrecognition can be handled without spoiling the convenience of the controller by the voice recognition.

Abstract: PURPOSE:To enable the surface to be wholly flattened, by projecting conductive layers, which are connected with lead terminals in the range of a gap between an outer periphery of a semiconductor integrated circuit chip and an inner periphery of the device hole, inside the device hole. CONSTITUTION:Respective conductive layers 6A and 6F are provided with terraced barrier parts 11, which are projected planely inside the device hole and over almost all the periphery of the device hole, and whose terminal ends neighboring the device hole 3 come nearly to the center of the gap between the outer periphery of a semiconductor chip 4 connected with the lead terminals 8 and 9 and the inner periphery of the device hole 3. Therefore, when the surface of the semiconductor chip 4 adhesively connected with the lead terminals 8 and 9 is coated with resin, the resin, which is situated on the upper part of the gap between the outer periphery of the semiconductor chip 4 and the inner periphery of the device hole 3, is essentially prevented from invading the lower part by the barrier parts 11. Hence, the surface of the coating resin can be wholly flattened without causing locally recessed parts on the resin.
