摘要:
Hair treatment compositions, hair damage protective agents and hair care products, each contain an active ingredient comprising an antibody which binds to human hair keratins which constitute intermediate-diameter filaments. This antibody can be produced efficiently and in a large quantities from the milk of a bovid animal immunized with said keratins. As this antibody binds to the hair specifically, it is effective in preventing the elution of proteins from the hair, imparting smoothness and flexibility to the hair, and improving the adaptability to combing and luster of the hair.
摘要:
A method for preparing a mixture of the halogenated alkoxyphthalocyanines represented by the formula (8) which comprises the step of reacting alkoxyphthalocyanines represented by the formula (7) and a mixture thereof with a halogenating agent in a mixed solvent of an organic solvent and water. ##STR1##
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 junction, such as a Schottky junction, is formed between a conductive electrode and a semiconductor. A bias voltage is applied between the conductive electrode and an outward-emission-side electrode formed on the semiconductor at the side opposite to the junction. Upon illumination, photoelectrons are internally emitted in the conductive electrode into the semiconductor, transported through the semiconductor, and emitted outward from the semiconductor surface, which has been so treated as to reduce the surface barrier height. The semiconductor is semi-insulating, or a p-n junction is formed therein.
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.
摘要:
A preparation containing an absorption promoter selected from N-acyl amino acid derivatives or N-acyl peptide derivatives represented by the formula: R-CO-A (R is an aliphatic hydrocarbon group, an aromatic hydrocarbon group or an aryl-substituted lower hydrocarbon group which may optionally be substituted, and A is an amino acid residue or a peptide residue), preferably in the presence of a salt at a concentation exhibiting higher osmotic pressure than isotonic sodium chloride solution, and a medicine is found to promote absorption of the medicine through a gastrointestinal organ such as the colon and rectum, and through the vagina.
