An investigation of the experiments and design of a double-hyperbolic nonplanar aperture type cosec²-beam horn antenna is described. The cosec²-beam radiation pattern is synthesized by a combination of two parts of hyperbolic apertures. The larger part is used as a main-part to concentrate the radiation power. The smaller part is used as a sub-part to fill in the electric field null due to the main-part.
The experimental results show that it is possible to obtain the high-gain and broad-band cosec2-beam horn antenna by using the E-plane sectoral horn whose aperture length is less than 10 wavelengths.

This paper describes a new simplified method of extracting Time Code information for video tape editing. The method uses the new simple fixed rate delay circuits which can be easily manufactured as LSIs. It can extract Time Code information at a rate from 1/31 to 130 times the normal tape running speed of VTR.
