A timing generator, includes: a first memory circuit that stores timing generation information; a first register for holding the timing generation information in the first memory circuit; a first external input part for accessing to the first register so as to rewrite data therein; a selector that selects one of the first memory circuit and the first external input part in order to conduct writing of data in the first register; and a pulse generation part that generates a pulse timing in accordance with the timing generation information held in the first register so as to output a single or a plurality of pulses. A pulse timing required for driving a solid-state imaging device and the like can be generated easily and the timing generation can be rewritten externally.

A counter circuit includes counting stages of n bits where n is a natural number. The counter circuit also includes a logic decoding circuit for determining the inputs of the counting stages, a logic circuit for adjusting the number of simultaneous changes so that the number of simultaneous changes of the logic decoding circuit can be made uniform, and a logic circuit for adjusting the load capacitance of the counting stages so that the load capacitance can be made uniform. The counter circuit may also include a test logic circuit for creating a test wave form on the basis of the outputs from the logic circuits for adjusting the number of simultaneous changes and the logic circuits for adjusting the load capacitance. Accordingly, it is possible to detect a failure of the logic circuits for adjusting the number of simultaneous changes and the logic circuits for adjusting the load capacitance which does not effect the counting output.

Driving circuit for solid-state image sensor and counter circuit used

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.

Disclosed is a novel beta-D-glucan derived from a microorganism of the genus Aureobasidium. The beta-D-glucan exhibits physiological activities such as an activity of accelerating excretion of heavy metals, anticholesteremic-activity, and an antioncotic-activity via the cellular immune system.

Beta-D-glucan, and its production and uses

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.

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.

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.

Described is a polysaccharide polyol derived from Volvariella volvacea, which is comprised of the following three types of recurring units. ##STR1## wherein D-Glu is D-glucopyranosyl residue, each number represents the linkage position, X is HOCH.sub.2 CH(CH.sub.2 OH)--O--CH(CH.sub.2 OH)--O--[Formula A] or D-glucopyranosyl and Y is --CH.sub.2 --CH(CH.sub.2 OH)--O--CH(CH.sub.2 OH)--O-- or D-glucopyranosyl, at least a part of X in the recurring units II and III is that of formula A, and, the average number of III is about 4-12 and the average number of the sum II and III is about 16-23, per 100 of the sum of I, II and III. 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.

A method for driving a solid-state image sensor in which the bias charges in a horizontal readout CCD (charge-coupled device) shift register are transferred onto vertical signal lines with the signal charges and then the signal and bias charges are transferred back into the horizontal readout CCD shift register from which are read out the signal charges (generated at the photosensor or photodiodes).
