Title: Crt video device
Inventor: TABUCHI HIDEHO
IPC: H04N3/223
Filed: 1978-08-11
Abstract: PURPOSE:To increase the raster width according to the size of the video image without lowering the sharpness of the image displayed on CRT by adding the means to modulate the vertical saw-tooth wave signal. CONSTITUTION:With supply of video start signal (a), the integration is started for vertical synchronous signal (b) through integrator 12 to obtain vertical synchronous integration signal (e). Signal (e) is supplied to adder 14 via attenuator 13 to be added with vertical saw-tooth wave (c). Thus modulated additional vertical saw-tooth wave (f) is obtained by modulation the vertical saw-tooth wave with DC signal (e) which is proportional to the number of the vertical saw-tooth wave. Wave (f) is then supplied to deflecting coil 11. Integrator 12 is reset by counter 15 which counts signal (b) and at count number n. Thus the raster shifts continuously until the number of the vertical synchronous signal reaches n registered to counter 15 and without following the same locus.

Title: Magneto-resistance effect type head
Inventor: KATAHASHI HISASHI
IPC: G11B5/39
Filed: 1985-05-10
Abstract: PURPOSE:To obtain a magneto-resistance effect type head which has high mass productivity and high electromagnetic conversion characteristics and can reduce the Barkhausen noises down to such a level where they can practically neglected, by providing the magnetization easy axes parallel to the rubbing surface against a medium to both front and rear flux guides. CONSTITUTION:When flux guides 3 and 4 have the uniaxial anisotropy parallel to a rubbing surface 10, a 90 deg. magnetic wall 12 can move easily toward a magnetic field shown by an arrow head in an unreversible way. However the occupying ratio of the wall 12 is very small in comparison with that of a 180 deg. magnetic wall 11 among those magnetic walls of flux guides. Furthermore the wall 12 is sufficiently distant from the center part of a magneto-resistance effect element. Therefore the effect of the unreversible movement of the wall 12 is extremely reduced to said effect element. That is, the Barkhausen noise level can be reduced by giving the uniaxial anisotropy parallel to the surface 10 to both guides 3 and 4.
