Title: Method for measuring activity in core of blast furnace
Inventor: KUMAOKA TAKASHI
IPC: C21B5/00
Filed: 1995-05-18
Abstract: PURPOSE: To measure an activity of the whole furnace core at the time of stopping blasting in a blast furnace. CONSTITUTION: Metallic rods or metallic pipes 4 are inserted in from arbitrary tuyeres 5 at >=4 positions at the time of stopping the blasting in the blast furnace, and an insert velocity till reaching a prescribed insert depth, is measured. At this time, a range until negative acceleration to the insert direction from the tip part of the tuyere becomes the max., is defined as a raceway depth, and the raceway depth in the case of being at 1400 deg.C the premeasured temp. at the furnace core part is taken as a reference. When the receway depths in half number of the driven-in positions are lower than the reference receway depth, it is judged that the furnace core part is inactive.  Otherwise, at the time of measuring the insert velocity, the insert velocity at the time of passing through the inner part in the furnace core at 2.5m deep position from the tip part of the tuyere is defined as a digging velocity and the digging velocity in the case of being at 1400 deg.C the premeasured temp. at the furnace core part is taken as a reference. When the digging velocity in half number of the driven-in positions are slower than the reference digging velocity, or when the min. digging velocity is <=0.7 times of the reference digging velocity, it is judged as that the furnace core part is inacitive.

Abstract: PURPOSE:To detect the displacement and angle when a knob is operated within three-dimensional space by detecting the expansion/contraction displacements of six legs. CONSTITUTION:When a pilot turns a knob 1 with displacement in a desired direction, the six legs expand and contract and the leg expansion/contraction displacement signals Sa-Sf are delivered from the expansion/contraction displacement detectors 4a-4f set at those six legs. Then the signals Sa-Sf are supplied to a converter 7 via a signal processing part and processed based on an approximate equation obtained when the expansion/contraction displacement value is extremely small compared with the lengths of those legs. Here the errors caused by the flexion of a control stage 2 and a 5 are neglected. In such a way, both the displacement and angle can be detected in a simple way when the pilot operates the knob 1.

Title: Television receiver
Inventor: TAKAHASHI YUKIO
IPC: H04N7/015
Filed: 1990-05-10
Abstract: PURPOSE:To decrease a level change when the state changes from a still state to a moving state (or vice vesa) by forming a frame sum signal from a high frequency signal outputted from a frequency difference extraction circuit, using a changeover switch so as to select either the frame sum signal or the high frequency signal and adding the selected signal to a low frequency signal of the video signal. CONSTITUTION:A frequency difference extraction circuit 11 executes the extraction processing of a high frequency component and its output is fed to a frame difference and sum component signal generating circuit 30. The frame difference signal is subject to absolute value processing by an absolute value processing circuit 20 and compared with a reference level at a comparator 21. Thus, a high level switching control signal is obtained for only a large state change of the video signal thereby operating a changeover switch 15. Since a frame sum signal being a correction signal is fed to a reduction signal as a result, a steep level change in the output video signal is corrected.

Filed: 1980-09-02
Abstract: PURPOSE: To suppress segregation and improve quality by providing a 3-layer type feeding flask on the inner side wall of a mold, and casting a steel ingot while suppressing the solidification from its side walls.  
     CONSTITUTION: A feeding flask 2 is provided on the inner wall of a mold 1 placed on a molding board 3. The flask 2 consists of the three layers, a heat insulation layer 2a in contact with the entire surface of the inner wall of the mold 1, a heat evolving layer 2b in contact with the entire inside surface of said layer 2 and a heat insulation layer 2C in contact with the entire inside surface of the layer 2b. If a steel ingot is cast by providing such flask 2, the head part of the flask 2 reduces head part segregation and V segregation by the cooperation with a head part heat insulating material 4. In the steel ingot middle part of the flask 2, the surface is kept smooth as the heat insulating material 2c in contact with the ingot withstands collapsion owing to heat; in addition, the occurrence of inverse V segregation by the solidification from the side surfaces of the ingot is suppressed by the heat evolution and insulation functions of the flask 2. Consequently, the formation of the negative segregation in the bottom part accompanied with the formation of the inverse V segregation is obviated, and the sound steel ingot is obtained.

IPC: G11B5/02
Filed: 1988-05-17
Abstract: PURPOSE:To prevent disturbance to a reproducing picture by the frequency of an AC power supplied to a pre-amplifier from being prominent visually by setting the frequency of the AC power to be supplied to an amplifier being rotated with a video head equal to the half of odd times the horizontal scanning frequency of a video signal. CONSTITUTION:A demodulation luminance signal is supplied to a synchronizing separator circuit 13, then, a horizontal synchronizing signal is outputted, and the horizontal synchronizing signal is inputted to a multiplication circuit 14, and the frequency of the signal is N-multiplied. Following that, the N-multiplied signal is inputted to a frequency division circuit 15, and is 1/2-frequency divided at the circuit 15. At this time, N is odd number, and the output of the frequency division circuit 15 triggers an OSC(oscillator for power source)5. therefore, the oscillation frequency of the OSC5 goes to the half of the odd times the horizontal scanning frequency of the video signal, and when the output of the OSC5 is mixed in the video signal, a disturbing point 22 appears at every horizontal scanning lines (17-21) in a state where a phase is inverted. In such a way, the negation of the horizontal scanning lines with each other occurs, thereby, it is possible to prevent the disturbance from being prominent visually.
