    摘要: A logic circuit outputs state signals of seven different kinds, on the basis of first, second and third digital signals. A first composite gate circuit outputs a logical OR among the first to third digital signals as a first state signal. A first gate circuit outputs a logical OR between the second and third digital signals as a second state signal. A second composite gate circuit is supplied with a logical AND between the first and second digital signals, and outputs a logical OR between the supplied logical AND and the third digital signal as third state signal. A third composite gate circuit is supplied with a logical OR between the first and second digital signals, and outputs a logical AND between the supplied logical OR and the third digital signal as a fifth state signal. A second gate circuit outputs a logical AND between the second and third digital signals as a sixth state signal. A fourth composite gate circuit is supplied with a logical AND between the first and second digital signals, and outputs a logical AND between the supplied logical AND and the third digital signal as a seventh state signal. The third digital signal is output as a fourth state signal without being processed. Each of the above circuits has an emitter coupled logic structure.

    摘要: When cells are analyzed, fractionated, and incubated while keeping the cells alive, real-time operations can be performed more easily and the cells can be incubated while removing unnecessary cells from the incubated cells to purify the cells being incubated. Furthermore, desired cells are separated through analysis from the incubated cells, and the purity, recovery, and viability of the cells are heightened. Use is made of a substrate having photo-controllable cell adhesion properties, the substrate comprising a transparent base and, formed thereon, a film of a material which has photo-controllable cell adhesion properties and has been obtained by bonding a cell-adhesive material to a cell-non-adhesive material through photo-dissociable groups. Cell images are detected and analyzed to obtain information about the location of desired cells. On the basis of the information, a space is formed between cells and the material having photo-controllable cell adhesion properties is cut, by means of second light irradiation. Meanwhile, by means of first light irradiation, the surface of the substrate is changed from a cell-adhesive surface to a cell-non-adhesive surface, thereby separating the cell(s) from the substrate. Thus, cells can be analyzed and fractionated while keeping the cells alive.

    摘要: A Booth's algorithm conversion circuit having first and second switches controlled by input signals QX and Q2X and receiving as input, signals X.sub.i of a logic level positioned in the i digit order of a multiplicand X and signal X.sub.i-1 of a logic level positioned in the i-1 digit order of multiplicand X. The outputs of the first and second switches are tied together and to ground via first and second transitors controlled by signals QX and Q2X, the first and second transistors conducting in an inverse relationship to the first and second switch circuits. The common output of the first and second switch circuits is input to an exclusive OR circuit which receives an additional logic 1 or logic 0 input signal to produce the Booth's converted output. The resulting number of circuit elements and gates provides a simplified, high speed and small circuit for producing the Booth's conversion.
