摘要： NEW MATERIAL:A compound expressed by formula I (A -A are H or substituent group having acryloyl or methacryloyl). EXAMPLE:Monoacryloyloxyethyl ester of 3,4-dicarboxy-1,2,3,4-tetrahydro-1 naphthalenesuccinic acid (referred to as TDA). USE:A raw material for curable resin compositions having high a hardness and strength, excellent curability, adhesive property as well as heat resistance and useful as a raw material for coating materials, inks, adhesives, molded articles, etc. PREPARATION:TDA anhydride expressed by formula II is reacted with an acrylic compound, having hydroxyl group and expressed by formula III is 50-150 deg.C for several hr to afford the aimed compound expressed by formula I. The reaction, if necessary, is carried out in a solvent, e.g. benzene, etc., using a catalyst, e.g. triethylamine, etc., a thermal polymerization inhibitor, e.g. benzoquinone, etc.

摘要： PURPOSE:To obtain a rust and corrosion inhibitor for metals having superior performance by using salts of 3,4-dicarboxy-1,2,3,4-tetrahydro-1-naphtha lenesuccinic acid or a partially esterified product of the acid as principal components. CONSTITUTION:This rust and corrosion inhibitor having significant rust and corrosion inhibiting effects on various metals such as steel, Al and Zn, especially on Cu is an aqueous soln. contg. 0.01-5wt% one or more kinds of salts of 3,4-dicarboxy-1,2,3,4-tetrahydro-1-naphthalenesuccinic acid (TDA-W) or a partially esterified product of the acid as effective components. The salts are selected among alkali metallic salts such as K and Na salts, alkaline earth metallic salts such as Ca and Ba salts, and aliphatic, aromatic and heterocyclic amine salts.

摘要： PURPOSE:To promote atomization of fuel, by opening an orifice and annular groove of sectional area larger than that of the orifice in the throat part of a carburetor fully throughtout an inner circumferential surface of the throat part. CONSTITUTION:In a throat part 2 forming the venturi, a slide valve, not shown in the drawing, having a warhead-shaped point end, is vertically moved to change are of the venturi. The throat part 2 consists of upper and lower parts 12, 22, and an annular orifice 4 is formed by an annular rib 97 in the upper part 12 and a spacer 19 in the lower part 22. Further in the downstream side of the orifice 4, an annular sump 9 is formed by an annularly protruding part 99 of the upper part 12 and annularly hollowed part 96 of the lower part 22. Then the sump 9 is formed larger in section than the orifice 4, further the downstream side of the sump 9 is opened fully circumferentially to an air passage 1. In this way, since fuel is supplied to annularly flowing air in the venturi fully from its circumference, uniformity of mixture can be easily obtained simultaneously satisfactory atomization can be also performed.
