Abstract: PURPOSE:To improve the operability of component video equipment by enabling automatic discrimination to be performed by calculating the correlation coefficient of a digitized component video signal, and discriminating the format of an input signal based on a comparison signal obtained by comparing with a threshold value. CONSTITUTION:Input component video signals (a1-a3) are changed to digital signals (b1-b3) by A/D converters 4-6, and the correlation coefficients (c1-c3) are calculated by correlation coefficient calculators 13-15 by combining every two signals out of b1, b2, and b3. They are compared with the threshold values (d1-d3) by comparators 19-21, and the comparison signals (e1-e3) obtained assuming as one when c>d and as zero when c<=d are supplied to a signal format discriminator 25. The discriminator 25 adds the comparison signals (e1-e3), and discriminates that the input video signal is of GBR format when an addition value n>2, and it is of format consisting of a luminance signal and a color difference signal when n<=2. Thereby, it is possible to heighten the operability by enabling the automatic discrimination of the format of the component video signal to be performed.

Title: Liquid level gage
Inventor: HAYASHI CHIKAHISA
IPC: G01F23/74
Filed: 1984-05-31
Abstract: PURPOSE:To reduce linearly an inductance according to the movement upward of a float and to obtain a high measuring accuracy by changing a winding wire density in order that the magnetic flux intersecting at right angles with a conductor ring becomes maximum around the upper end part of a coil. CONSTITUTION:The density of a magnetic flux intersecting at right angles with a conductor ring 18 is made maximal around the upper end part of a coil 12 with non-symmetrizing the distribution of the magnetic flux leakage by providing continuously a thick winding part 14c on the upper part of a plain winding part 14b in the coil 12 of the detecting part. The position of the ring 18 where the inductance becomes minimum is therefore ascended nearly upto the upper end of the coil and the inductance is reduced according to the movement of the float. The rise of the inductance around the part filled up with fuel is also stopped by changing the distribution of the leakage of magnetic flux with providing un-winding parts 14a, 14d. Consequently the inductance of the coil 12 can be changed linearly by the displacement of the float.

Title: Thermal type overcurrent relay
Inventor: KOJIMA TOSHIHARU
IPC: H01H61/013
Filed: 1988-05-11
Abstract: PURPOSE:To improve a resistance against critical overcurrent without increasing kinds of bimetal by providing an electrothermal amount adjusting device near a bimetal supporting part. CONSTITUTION:By the heat generating from a bimetal 3 itself and a heater 2 wound around the bimetal 3 via an insulating paper 5, the bimetal 3 is deformed and bent so that it moves an interlocking plate 6 and makes a contact point switching mechanism work inversely. And by providing an electrothermal amount adjusting device 7 near a bimetal supporting part, the amount of heat generated near the bimetal supporting part increases in comparison with other parts of the main bimetal 3 and at the same time, thermal resistance increases, and then the heat around the central area of the bimetal hardly escapes to a terminal plate. Consequently, the heat generation of the bimetal 3 is controlled, and while the actuation characteristic can be made in any shape freely, the resistance against critical overcurrent can be easily improved by means of the same bimetal material as that of the bimetal 3 in its own resistivity, bulge constant, thickness and width of plate.
