Title: Ferrite core
Inventor: KIJIMA SEIICHI
IPC: H01F27/255
Filed: 1989-01-13
Abstract: PURPOSE:To reduce a compound transformer in its size by performing protrusion formation of the inner-side surface of left and right legs, and performing curved formation of both side surfaces of central leg where each inner side surface of left and right legs oppose each other, and then connecting a central leg and left and right legs in one piece with a plate-shaped yoke which is narrower than the leg width of the central leg and wider than the leg width of left and right legs. CONSTITUTION:Both legs of a central leg 9S of a core 9 are expanded in a fan shape along the outer surface of coils 11 and 12 and the thickness of the central part of this central leg 9S is formed thinly. Then, the inside surface of left and right legs 9L and 9R which are placed symmetrically at both sides of the central leg 9S is protrudingly formed. Thus, the length 3l between outer surfaces of the coil in the left and right leg direction is reduced and the length 3d between the outer surfaces of the coil in the direction of core width is also reduced. Thus, the size of outer shape of a compound transformer can be reduced and an area for incorporating a transformer into an electrical appliance can be reduced.

Filed: 1983-01-17
Abstract: PURPOSE:To obtain easy-to-see profile correction picture without eliminating noise by extracting a high frequency component being a prescribed frequency or over of a luminance signal and limiting its amplitude so as to obtain a profile correcting signal. CONSTITUTION:A luminance signal is fed to two second order high pass filters (HPF)3,4.

The amplitude of an output of the 2nd order HPF3 is limited by a clip circuit 5 and a level of a prescribed value or over is cut off. The 2nd order HPF4 extracts selectively a high frequency component >=4-4.5MHz, and a small signal being a prescribed level or below is eliminated by passing its output through a slice circuit 6. An easy-to- see picture is obtained by synthesizing both outputs and the original luminance signal at a synthesis circuit 2.
