Title: Method for driving descaling pump in hot-rolling of steel
Inventor: YANASE KOICHI
IPC: B21B45/08
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To drive a pump without remarkably lowering the pressure in an accumulator and further, without the power loss, by predicting the member of descaling pumps in a prescribed time from a loaded tracking with a rolling material and a jetting pattern, and controlling the output of the pumps based on this prediction. SOLUTION: The water amount required for the descaling jetting is predicted by using the information in which it is preset for each rolling material whether the descaling jetting is executed or not at each stand from the jetting pattern. When the descaling jetting is executed, at the setting time for executing the jetting, this descaling jetting is controlled so as to open the jetting valve by detecting a timing (i) of the jetting start (according to the positional tracking of the rolling material). In the prediction of starting the descaling jetting, the predicting timing (j) of the jetting start can newly be set before the timing (i) of the jetting start. When the execution of jetting is set, it can be judged whether the jetting is executed or not before actually starting the descaling jetting by detecting the timing (j) of the predicted starting of jetting.

Filed: 1989-04-13
Abstract: PURPOSE:To provide a title device with high current density and satisfactory controllability by connecting a MOSFET formed on a thylister substrate to one, emitter layer and an adjacent base layer. CONSTITUTION:A first gate 91 is connected to a gate terminal G1 with a second gate 92 connected to a gate terminal G2, and an emitter electrode 10 connected to an emitter terminal E makes contact with a source layer 6. A first drain layer 81 is connected to an N emitter layer 4 through a wiring 11 with a second drain layer 82 connected to a p-base layer 3 through a wiring 12. An anode electrode 13 connected to an anode terminal A makes contact with a p-emitter layer 1. Accordingly, the device can be driven in its on/off operation by an insulating gate. Further, since a thylister is used to permit a current to flow substantially over the entire surface of the semiconductor substrate in a thickness direction, current density can be made high. Additionally, since there is no parasitic effect, there is no problem of the device being broken down by latching-up. Thus, the device can securely be switched on/off by gate driving at high current density.

Title: New diaper having pocket structure and its production
Inventor: FUKUI HIROAKI
IPC: A61F13/514
Filed: 1992-04-14
Abstract: PURPOSE:To assure excreta in a pocket part so as to prevent the leakage thereof and to form a hydrophobic surface sheet so as to make tearing force absorbed by forming a pocket part between the hydrophobic surface sheet and an absorbent and liquid impermeable back sheet. CONSTITUTION:The hydrophobic surface sheet is formed by superposing the peak part and peak part of two sheets of sheets and is formed of flank parts A, B, C which is the overlapped part of A and B, an aperture D and a peripheral edge E where the hydrophobic surface sheet and the back sheet are bonded by disposing the valley part and valley part opposite to each other. The non- bonded part of the peripheral edge E has the structure floating from the absorbent part of the diaper and forms the pocket structure from the periphery of the aperture D to the part E. As a result, the overlapped part C moves according to the motion of a wearing person and, therefore, the diaper does not break even if the strength of the surface sheet is not so high. In addition, the large deviation in the position of the hole does not arise either.
