Title: Immersion nozzle for continuous casting
Inventor: SASAI KATSUHIRO
IPC: B22D41/58
Filed: 1992-09-25
Abstract: PURPOSE:To prevent bulging defect in a cast slab and improve the quality by arranging a connecting part partially and integratively connecting a nozzle body and an inner hole body corresponding to a gas blowing part to annular- state along a powder line and making SiO2 content in the inner hole body the specific value or lower. CONSTITUTION:In an immersion nozzle, the connecting part 4 partially and integratively connecting the nozzle body 2 and the immersion nozzle inner hole body 1 corresponding to the gas blowing part, is arranged as the annular- state along the powder line 3. Further, the SiO2 content in the inner hole body 1 is made to be <=5wt.%. By this immersion nozzle, the erosion resistance and the spalling resistance are secured and besides, the fine bubbles can stably be blown from the inner hole body 1. Therefore, not only the prevention from the bulging defect, but also the prevention from float-up separation of inclusions caused by the bubbles and from nozzle clogging, can further efficiently be executed. By this method, the quality of the cast slab produced by continuous casting method is stabilized and the yield is improved, too.

IPC: G06T3/40
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To change the dimension of a video image by using the average value weighted in an area of input picture elements so as to calculate a weighting coefficient integrated by the luminance and chromaticity of the input picture elements.

IPC: G03G15/08
Filed: 1989-10-27
Abstract: PURPOSE:To expand an application range by sucking the developer stagnating in a thickness regulating part by a magnetic device and dropping the developer in a position apart from the thickness regulating part, and thereby removing the developer from the thickness regulating part. CONSTITUTION:While a toner is held accumulated in the thickness regulating part, a permanent magnet 10 is moved from a suction releasing position (b) to a suction position (a) by running a stepping motor, by which the stagnating toner D is suck and is attracted to the rear surface of a blade mounting plate 7. The attracted toner D moves together with the magnet 10 along the blade mounting plate 7 when the permanent magnet 10 is moved toward the suction releasing position (b) in this state. This toner D is relieved from the suction force of the permanent magnet 10 in the suction releasing position (b) and falls toward the upstream side of the toner supply of a developing roller 4. The stagnating toner D in the thickness regulating part is removed in such a manner. The application of this device to a thin layer forming member of a small angle is possible in this way and the application range is widened.

Filed: 1984-12-28
Abstract: PURPOSE:To obtain a device allowed to start copying operation only when toner in a developing unit is uniformly dispersed by detecting the mixed state of the toner with carrier, driving an agitation means independently and starting the copying operation after checking the uniform mixing. CONSTITUTION:When large variance is generated in toner concentration between the end part and the center part of the developing unit, a temperature difference detecting circuit 20 outputs a signal. A copying operation stopping circuit 22 inhibits copying operation, rotates an agitation screw independently and starts a counter simultaneously, a developer is agitated and the counter 23 counts up the number of times of agitation. When the counted value of the counter 23 reaches a fixed value, a reference pattern line is formed again to detect the variance of picture density in a range covering a sheet of B4 size. When the developer is agitated and the toner in an area corresponding at least to the original size is uniformly distributed, the circuit 20 output a temperature difference signal of the low level. Consequently, the circuit 22 stops the rotation of the screw and a copying operation stop releasing circuit 25 lights up a copying available display unit 26 and resets the counter 23 simultaneously.
