Title: Contact limiting plate in twin drum type continuous casting
Inventor: SHIO KIYOMI
IPC: B22D11/06
Filed: 1995-01-27
Abstract: PURPOSE: To prevent the generation of an air gap between a solidified shell and a horizontal drum and to enable the growth of a solidified shell by bringing contact projecting parts into contact with the horizontal drum and forming a spacing between a contact limiting plate and the horizontal drum. CONSTITUTION: The bottom end of the contact limiting plate 1 is pressed to the horizontal drum 2 by the static pressure of molten metal when the contact limiting plate 1 is mounted and arranged at a holder rotating freely around a stationary shaft. The contact limiting plate 1 has the contact projecting parts 15 in the positions corresponding to both ends of the horizontal drum 2 to form the spacing (t) between the front end 14 of the contact limiting plate 1 and the horizontal drum 2. Since the front end 14 of the contact limiting plate 1 and the horizontal drum 2 is contactless, the refractory powder and inclusion flaws by wear, etc., are no longer generated and the heat of the solidified shell is removed into the horizontal drum 2. The smooth growth of the solidified shell is thus possible.

Title: Pll circuit
Inventor: YOSHIMURA MINORU
IPC: H03L7/085
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To secure both the speed and stability of locking by selecting and using error signals whose duty factors are different in accordance with a phase pulling stage. SOLUTION: 1st and 2nd pulse generating parts 7 and 8 in a phase difference detector 3 respectively generate pulse trains according to comparison results of a phase comparing part 1. A selector 9 selects one between them according to a control signal. For instance, the part 7 generates a cyclic pulse whose duty factor is small and the part 8 generates a cyclic pulse whose duty factor is large. When power is inputted or when the circuit is started from an input clock disconnection state, phase pulling control is performed with a pulse with a large duty factor. Since a voltage controlled oscillator 5 operates in accordance with the integration of an error signal outputted from the part 1, even though the locking speed increases in such a case, pulling stability is sacrificed. Once locking is completed, control is performed with a pulse with a small duty factor to increase stability.

Abstract: PURPOSE:To prevent data from being destructed by recording a signal of a specific pattern in a forward area on a recording medium and deciding such a block as a nonrecorded part that only when the specific pattern is normally reproduced from a reproducing system, but the following data part is not reproduced. CONSTITUTION:The specific pattern 50a is recorded in a gap part 50 between a preformat part 33 and the data part 34. When a changeover signal 38 is generated by a timing generator 30, immediately after changing a switch 22 to 21, the pattern 50 is reproduced, and whether a reproducing circuit is normal or not is decided by a decision circuit 31 via a pulsification circuit 27. Then, only when the normality of the reproducing circuit is decided but the following data part is not reproduced, this block is decided as the nonrecorded part by a control circuit 30. By this method, an old data is prevented from being destructed in mistake for a nonrecorded part due to damage of the reproducing system.

Title: Manufacture of base substrate for superconducting element
Inventor: YOSHISATO MASANOBU
IPC: C04B35/45
Filed: 1989-01-20
Abstract: PURPOSE:To eliminate adverse affects to superconducting characteristics by heat treating an amorphous material obtained by mixing raw materials for a superconducting element, melting and quenching the mixture. CONSTITUTION:Raw materials for a superconducting element are mixed and plasma molten within an atmosphere of argon gas. The melt is quenched at a predetermined cooling rate to make it amorphous. The mixture thus obtained is heat treated and then cooled gradually to ordinary temperature to provide a polycrystalline body consisting of aggregation of single crystal bodies. Then, a substrate is obtained by cutting a single crystal body out of the polycrystalline body. In this manner, a single crystal base substrate having the same composition as that of the raw materials for the superconducting element can be obtained. Therefore, it is possible to prevent diffusion of a dopant to the superconducting element provided on the substrate. As a result, adverse effects from the substrate can be eliminated completely.
