    摘要: There is here disclosed a method for preparing an alkoxyphthalocyanine represented by the formula (1): ##STR1## wherein each of Rs is independently a secondary alkyl group having 3 to 20 carbon atoms, Met is a divalent metal atom or an oxy metal, and the substitution positions of -ORs are the 1- or 4-position, the 5- or 8-position, the 9- or 12 position, and the 13- or 16-position, which comprises the steps of heating a mixture of 3-alkoxyphthalonitrile and an organic base in an alcohol to 90.degree.-120.degree. C., adding a metal derivative at the same temperature, and then carrying out reaction, or alternatively the step of reacting a mixture of a 1,3-diimino-4-alkoxyisoindoline and a metal derivative in the presence or absence of an organic base in an aliphatic alcohol having 6 or more carbon atoms. In addition, the ratio of isomers of the alkoxyphthalocyanine can be controlled by regulating the addition time of the organic base.

    摘要: A plurality of ultra-high speed light receiving elements are provided each of which has two rectifier junctions being connected to each other opposite in polarity and has a substantially symmetrical electrode arrangement. A bias voltage is applied to each of the light receiving elements from one or a plurality of power sources. Electrical signals produced by the light receiving elements in response to input optical pulse signals are superposed on one another to produce one or a plurality of output electrical signals representing a predetermined logic operation with respect to the input optical pulse signals. Depending on the arrangement of its elements, the optical logic operation system functions as an OR circuit, AND circuit, NOT circuit, EXCLUSIVE OR circuit, or half-adder circuit.
