Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To surely join a pair of magnetic core half bodies and to eliminate the defects in a gap length and the joining by forming non-magnetic metallic materials at both end sections at the joining surface of the bodies and constituting a magnetic head by metallic diffusion joining using the formed non-magnetic metallic material. SOLUTION: During the joining of a pair of magnetic core half bodies 2 and 3 of a magnetic head 1, gold films are formed on regions R, back section butting surfaces 11 and coil connecting terminals 13 and the bodies 2 and 3 are joined through the films. The regions R are located at the both end sections in the height direction of the head 1 and no gold film is formed in the portion sandwitched by the regions R. Thus, the head 1 is formed by joining the bodies 2 and 3 using the films mainly formed in the regions R. In other words, the portion sandwitched by the regions R is not related to the joining process.

Title: Method and apparatus for compressing digital video color data
Inventor: ERITSUKU EMU HOFUAATO
IPC: H04N11/04
Filed: 1991-03-15
Abstract: PURPOSE: To adaptively compress/restore video data to obtain an aliasing prevention mode by checking (n×n)-picture element blocks of picture element data to judge which compression system should be used, for every block. CONSTITUTION: Video data is divided into blocks of n×n picture elements, for example, 4x4 picture elements, and different colors are settled for them. That is, they are obtained by averaging colors whose luminances are higher and lower than the average luminance of blocks. Generally, two different colors are calculated in an RGB space. The difference between these two colors is checked; and if this difference is larger than a first threshold, at least two colors and an n×n-bit map are stored to store the picture element data block. When it is smaller than the first threshold, the picture element data block is stored as a single color without a bit map. At the time of decoding, two colors are obtained by calculation, and bit map data is used to select one of four colors for every picture element.

The reset signal and latch signal can be outputted while one pulse delayed behind the light emission signal Pa which is outputted in specific cycles. When the light receiving signal Sa varies greatly after one light emission pulse is sent, that is outputted to a decision means 5 with the latch signal right after it.  The decision means 5 outputs an alarm signal Se when the value of a data signal inputted from an integrating circuit is larger than a reference value.
