Abstract: A counter circuit which incurs a uniform number of logic changes whether the clock signal is rising or falling is used in both a first counter circuit for measuring the reference signal for horizontal scanning period and a second counter circuit for measuring signals in the vertical blanking period. Since the number of logic changes of the flip-flops with respect to the clock signal is uniform, a driving circuit for a solid-state image sensor is realized in which noise in the vertical blanking period does not appear in the video period even if by using 1H delay line.

Abstract: A solid state image sensing device which transfers unnecessary signal charges accumulated at photoelectric conversion devices by a first charge pulse in a vertical blanking period to vertical transferring means and throws out the unnecessary signal charges using throw-away means. The necessary signal charges accumulated in the photoelectric conversion devices in such period after the first charge pulse are transferred by a second charge pulse to the vertical transferring means, a horizontal transferring means and a signal detecting means, thereby to issue a video signal.

Abstract: A novel beta-1,3-glucan (ganoderan) is produced by culturing a microorganism of genus Ganoderma. Ganoderan is composed of a backbone structure of beta-1,3-linked D-glucopyranose residues bearing, at some of the C-6 positions, side chains of single beta-1,6-linked D-glucopyranose residue, and, at some of the C-2 positions, side chains of another type wherein 2-4 D-glucopyranose residues are linked via beta-1,4-linkage. Hydrogenation of ganoderan leads to the formation of a polyol-type ganoderan. Intact- and polyol-type ganoderans both having a strong antioncotic activity. They are usable in chemicals, food products, pharmaceuticals, etc.

Abstract: A color filter is constituted by unit arrays of two columns and four rows of filter elements. The first column has cyan, magenta, cyan, and green (or green, yellow, green and cyan) filter elements which are arranged in that order and the second column has yellow, green, yellow, and magenta (or magenta, cyan, magenta and yellow filter elements which are arranged in that order. A solid state image apparatus having an expanded dynamic range is realized by using this color filter in that the dynamic range of the photoelectric elements corresponding to the green filter elements can be utilized more efficiently.

The polysaccharide is prepared by extracting Volvariella volvacea with an aqueous alkali solution and oxidizing and then reducing the soluble fraction to cut parts of C--C bonds of side chains. The polysaccharide is useful and an anti-tumor agent.
