Title: Apparatus for controlling variation of molten surface
Inventor: UCHINO KAORU
IPC: B22D11/16
Filed: 1987-05-27
Abstract: PURPOSE:To prevent development of surface defect caused by including powder and occurrence of breakout caused by remelting solidified shell by arranging a controlling device controlling distance of a shifting device of colliding plates by transmitting output from a molten surface leveller to control variation of the molten surface into the suitable range. CONSTITUTION:The molten steel 15 in a tundish 10 is poured into a mold 20 from discharging holes 22 through a sliding nozzle 25 and submerged nozzle 21. The discharged flow 23 of the molten steel 15 from the discharging hole 22 is flowed toward short side wall through hole 31 in the colliding plates 30 and collides with the short side wall and divides into streams upward and downward. In the case of detecting the stream of the molten steel 15 with the molten surface leveller 40 as abnormal variation of the molten surface, which the variation degree of the molten surface is out of the suitable range, the colliding plates 30 are pulled up with supporting rod shifting devices 33 through the supporting rods 32. By this method, the lower side of the discharged flow 23 collides with the lower side of the hole 31 in the colliding plate 30 and changes its flowing direction and does not come to the short side of a mold. Therefore, the flow toward the molten surface 24 caused to much variation of the molten surface is weakened, and the variation thereof is made to little.

IPC: H01L21/312
Filed: 1989-05-22
Abstract: PURPOSE:To obtain a taper angle improving coverage by using a film which is formed by vapor growth and has compressive stress, as a mask instead of a metal mask. CONSTITUTION:On a polyimide film 4, a mask 6 having compressive stress is formed by vapor growth. An etching window 8 is formed in a mask film 6, and the polyimide film 4 exposed in the etching window 8 is etched, thereby forming a pattern having a taper on the side surface. By changing, in this manner, the compressive stress of the mask 6 formed on the mask 4 and etching the film 4, the amount of etching liquid permeating into the interface between the film 4 and the mash 6 can be adjusted based on the intensity of compressive stress. Thereby the etching rate of a part in the vicinity of the mask is changed, so that a taper angle is adjusted, coverage is improved, and further pattern density can be increased.

IPC: H04B10/272
Filed: 1991-05-01
Abstract: PURPOSE: To avoid the technical expenses of fine delays, using an analog delay line which can be set in addition to rough delays in a remote unit. CONSTITUTION: An exchange VSt sends a data burst to a remote unit DU, and the unit DU sends a determined burst within a reserved time slot. Various phase positions at the time of arrival at the exchange VSt, various propagation times, and the phase at each time are required to be corrected, so that data can be put within time slots assigned to them. In this case, fine delay in each remote unit is omitted, and fine delay selected for each DU of the arriving data burst is executed by a central fine delay device in the exchange VSt. The phase position to which the arriving data burst belongs is determined and stored, and corresponding fine delay is set by a control logic at the time of arrival. That is the arriving data is delayed by 1/n clock and is formed in an optimum reception phase position.  By this constitution, only a single fine delay line which can be set is required for all remote units, and the technical expense of a circuit is markedly reduced.

As the parameter of the discriminating function, the probability of the recognized result is added and while depending on the function value, the recognized result is rejected. Further, the probability of the recognized result for each character type to be stored in the table is defined as a value considering the rate of appearance for the character type or the rate of appearance for the character type is fixed. Thus, while considering easiness concerning the error of the character type, which is obtained according to the recognized result, to the other character type, the reject processing can be executed with much higher accuracy.
