Title: Apparatus for controlling continuous casting
Inventor: NISHIYAMA SHINJI
IPC: B22D11/108
Filed: 1987-03-02
Abstract: PURPOSE:To improve the quality and the yield of a slab by actually measuring continuous molten surface profile by a molten surface level meter, comparing it with the ideal profile and controlling powder supplying, casting velocity and the molten surface level based on the comparison. CONSTITUTION:The molten surface level meter 6 of ultrasonic level meter, etc., is arranged to a mold 3 and scanned toward mold width direction and short side direction (thickness direction) at the fixed periodic time. Then, effect characteristics of the mold 3 and a nozzle 2 are actually measured beforehand by output of the level meter and stored in a molten surface profile analyzer 7. On the other hand, the ideal profile is stored in the analyzer 7 by experimentation and theoretical study, and by comparing the measured profile of the level meter 6 with the ideal profile, the powder supplying, casting velocity and the molten surface level are controlled. In this way, slag entrapment caused by disturbance of the molten steel flow and shortage of the powder are prevented. Therefore, the quality and the yield of the slab are improved.

Title: Magneto-resistance effect head
Inventor: HASEGAWA YUUJI
IPC: G11B5/39
Filed: 1984-03-12
Abstract: PURPOSE:To improve reproduction efficiency even when recording wavelength is short by arranging an MR element and an auxiliary magnetic pole with high specific resistance in contact and suppressing a diamagnetic field in a strike width direction. CONSTITUTION:The auxiliary magnetic pole 26 has extremely large specific resistance, and has large saturated magnetic flux density and small initial magnetic permeability.

Filed: 1978-04-24
Abstract: PURPOSE: To prevent occurrence of the defective abnormal signal caused by the returning beam by decreasing the thickness of the plate at the tip part of the photo conducting target at the 5th grid of the electron gun assembly for the pickup tube.  
     CONSTITUTION: The 5th grid 11 is a cylindrical electrode which forms part of the electrostatic electronic lens for electron beam focusing purpose, and tip part A at the side of the photo conducting target is cut with angle θ of a constant inner circumference as shown in the figure, with the outer circumference cut out in such a slight amount as the flash removal.

As a result, the collision area is reduced for the returning beam from the photo conducting target, thus reducing the discharge amount of the secondary electron as well as the amount of the abnormal signals. The end face flat measurement l and angle θ are set most suitably  to 0.1mm W 0.06mm and 45° W 60° respectively from the viewpoint of the manufacturing know-how and effects.

Abstract: PURPOSE:To surely permit the simultaneoue operation of a number of motors even if a number of motor controllers exist under an industrial robot controller, by transmitting the signal for permitting the operation for revolving a motor shaft by the signal line different from the time information and angle information. CONSTITUTION:A motor controller 2 transmits the information that the motor operation start is enabled, into an industrial robot controller 1 by using a signal line 5 different from the information transmission passage 4 such as angle and time, when the state where the operation start of a motor 3 is enabled is generated. While, if the industrial robot controller 1 receives the signal that the motor operation start is enabled, from all the motor controllers 2, the signal for permitting the operation of the motor 3 is transmitted to each motor controller 2. Accordingly, the generation of the difference of the time of the operation start due to the difference of the time related to the information transmission between the motor controllers 2 is prevented by simultaneously transmitting the signal for permitting the motor operation to each motor controller 2.

Abstract: PURPOSE:To make it possible to generate the reproduced signals, which are free from the bear obstraction while having a high quality, by scanning a recording medium with a scanning stylus, which is equipped with such an electrode as has its width smaller than the track pitch of the recording medium. CONSTITUTION:A scanning stylus 40 is brought into scanning and sliding contact with the surface of a disk 30, which has a flat surface and which is equipped with such helical or concentric tracks as are recorded with major information signals as the variation in geometric shape without forming any stylus guiding groove, so that the major information signals are read out and reproduced as the variation in electrostatic capacity.
