    摘要： A steroid compound represented by the formula ##STR1## which has an excellent aromatase-inhibiting effect and is useful for preventing or treating diseases caused by estrogens, such as breast cancer, uterine cancer and prostatomegaly. This compound has an oxygen or nitrogen atom as the heteroatom at the position A of the ring D and the 7-position (substituent R.sup.1) of the skeleton is substituted by --S--R.sup.2 (wherein R.sup.2 represents hydrogen, lower alkyl which may be substituted by hydroxy, amino or lower alkoxycarbonyl, lower alkenyl, aralkyl, aryl which may be substituted by halogen, amino, di(lower alkyl)amino, lower alkoxy or lower alkyl, acyl, or lower alkoxycarbonyl), --S(O)m--R.sub.3 (wherein R.sup.3 represents lower alkyl; and m represents 1 or 2), or aralkyl.

    摘要： In the recording section of a system for recording and reproducing a television signal containing a video signal component and a sound signal component the length of recording time is increased for a given amount of recording medium by periodically sampling the video signal component, for example, for alternate frame periods, and the sound signal component and a delayed sound signal component obtained by means of an one-frame delay device are alternately sampled for the first half and the second half of each line period during the sampled frame period in order to be recorded on a recording medium and be reproduced from the recording medium. In the reproducing section, each recorded frame of the video signal component is reproduced twice in succession along with the sound signal component, and the reproduced sound signal component is sampled for the first half of each line period during the first reproduction of the recorded frame and for the second half of each line period during the second reproduction of the same frame.
