Title: Superconduction quantum interferometer
Inventor: ARIMA YUTAKA
IPC: H01L39/22
Filed: 1987-06-19
Abstract: PURPOSE:To generate a metastable state in fluxoid transition so that phase locking is applied stably by adequately setting the capacity of a capacitor connected in parallel to a Josephson junction. CONSTITUTION:The capacitor 4 is connected in parallel to the Josephson junction 3 and the capacity value thereof is adequately set, by which the entire magnetic flux penetrating the inductance of a superconducting ring 1 causes damped oscillation around the average value. The higher uncertainty than in the case of not generating the oscillation is rendered to the fluxoid transition point by this oscillation and the probability that the fluxoid transition is induced by the external magnetic flux smaller than the magnetic flux at the transition point in the case of not oscillating the same increases. Generation of a negative inclination in the step parts in the relation between the amplitude ¦Irf¦ of the high-frequency current flowing in an inductor LT and the time average value <¦VCT¦> of the voltage across the capacitor CT is thereby caused and the phase locking is easily applied.

Title: Continuous casting method for steel
Inventor: KAWAKAMI KIMINARI
IPC: B22D11/07
Filed: 1981-09-28
Abstract: PURPOSE:To prevent the generation of breakout in the stage of adding mold powder to a mold which is opened at both ends and casting steel continuously with said mold by applying ultrasonic oscillations to the mold and applying mechanical oscillations that satisfy specific conditions thereto. CONSTITUTION:The molten steel 4 in a tundish 2 is charged through an immersion nozzle 3 into a mold 1 which is open at both ends, and mold powder 7 is supplied onto the steel 4, then the ingot formed with a shell 5 is drawn gradually from the lower part of the mold 1. At this time oscillations are applied to the mold 1 by a mechanical oscillating means 6 and an ultrasonic oscillator 8. The means 6 applies such mechanical oscillations that the positive strip time tp satisfies the equation (f is frequency) to the mold 1. The ultrasonic oscillations are set at around 20kHz frequency and about 2-10mu amplitude. Thus the inflow rate of the powder 7 is assured above specified rate and the lubricating performance between the mold 1 and the shell 5 is improved.

Title: Color blurring correction device
Inventor: OGINO MASANORI
IPC: H04N9/28
Filed: 1989-06-16
Abstract: PURPOSE:To attain highly accurate color blurring correction over the entire pattern by selecting the number of relay grating points to be 4 times the number of representative grating points or over and to be 3 or over for each horizontal blanking period and interpolating the color blurring correction to remaining points based on a stored data so as to adjust a few representative grating points. CONSTITUTION:Signals XU, YU are fed to a source correction function generating means 11 to generate 25 kinds of correction functions fij(XU, YU). Thus, the permutation of (i,j) is 25 ways and the total number of permutation of the (XU, YU) is 256 and they correspond to grating points being the division of the screen into 16X16. Then the function value of fij(XU, YU) is inputted to a weight storage means 12 and an output defined by SIGMAkjifij(XU, YU) is obtained by the combination of 10-bit variable weight constant kji being an output of a weight coefficient generating means 13. Then the constant kji is easily and definitely decided depending on the quantity of the color blurring correction of 25 representative grating points. Thus, a few representative grating pints are used to correct the color blurring of the entire screen.

Further, in the acceleration slip control, the connection with the master cylinder A is cut off, and the selection control means H communicates to the second pressure source F. In this case, the piping passage between the selection control means H and the reservoir B communicates because of the opening of the opening/closing means P by the pressure difference between the master cylinder A side and an antilock control means G side of a selection control means L for acceleration slip.
