Title: Continuous casting device and method for molten metal
Inventor: FUJI TAKEHIKO
IPC: B22D11/04
Filed: 1992-04-10
Abstract: PURPOSE:To enable the production of a slab having good surface characteristics by forming a cylinder of plural conductive segments to form a casting mold and intermittently passing impulsive currents to the outer side of the casting mold. CONSTITUTION:The casting mold 10 is constituted of the plural conductive segments which are electrically insulated from each other and form the cylinder opening at the front and the rear. An induction coil 9 is disposed coaxially with the casting mold on the outer side of the casting mold 10 and the impulsive currents are applied to this induction coil 9. A molten metal is poured into a vessel 8 and a slab is cast from the casting mold 10. The electromagnetic pulse force corresponding to the static liquid pressure of a molten metal is applied to a solidified shell 12. The cast metal in the casting mold 10 receives such pinching force as to be confined within the casting mold 10 at every pulse period when the high-frequency pulse currents are supplied to the induction coil 9. The static liquid pressure of the molten metal and the pinching force are balanced and the metal is detached from the walls of the casting mold. The slag 15 having the good surface characteristics is thus obtd.

Title: High frequency probe for nmr
Inventor: YODA KIYOSHI
IPC: G01R33/20
Filed: 1989-04-12
Abstract: PURPOSE:To constitute the high frequency probe for nuclear magnetic resonance (NMR) which has two kinds of resonance frequencies by one probe by arranging a couple of capacitors for resonance orthogonally to each other and making their electrostatic capacities different. CONSTITUTION:When a high frequency voltage is inputted to a coupling coil 5a for electric feeding through a terminal 7a, a high frequency magnetic field is produced extending to the coil 5a and the capacitor 3 operates as a capacitor for resonance at this time, so a resonance current flows to the horizontal parts of conductor plates 1a and 1b, and 2a and 2b toward the coil 5a. Further, when electricity is fed by a coupling coil 5b for electric feeding, a high frequency magnetic field is produced extending to the coil 5b and a capacitor 4a operates as a resonance capacitor, so that a resonance current flows toward the coil 5b. At this time, the resonance frequencies f1 and f2 are determined by the inductances of the conductor plates 1a and 1b, and 2a and 2b and the electrostatic capacities C1 and C2 of the capacitors 3 and 4, but when the capacities C1 and C2 are different, the frequencies f1 and f2 are different, so the high frequency probe for NMR which has the two resonance frequencies can be constituted.

Abstract: PURPOSE:To prevent the increase of a memory capacity and the increase of the number of bits to be processed in the circuits succeeding the memory, by a method wherein first density data indicating a visual density over N-step gradation (N is an integer not less than 2) is inputted as input data and made corresponding to second density data indicating a printing-dot density at every other step of gradation.

A full adders 11 adds the output signal from an OR gate OR1 to the least significant bit of the output data from an A/D convertor 10. If the least significant bit is carried, a signal '1' is outputted from a carry output end CY. If the signal '1' is not outputted from the output end CY, the upper 3 bits of the result of the addition in the adder 11 are outputted from OR gates OR2-OR4; thus, the density data of 4 bits outputted from the convertor 10 is converted to the data of 3 bits to be outputted.
