Abstract: In the method of manufacturing an image display apparatus according to the present invention, a liquid photocurable resin composition that does not contain a thermal polymerization initiator is coated on the surface of a light-transmissive cover member including a light shielding layer or the surface of an image display member in a thickness thicker than that of the light shielding layer, and thereafter UV rays are irradiated in that state for curing to form a light-transmissive cured resin layer. Then, the image display member and the light-transmissive cover member are laminated to each other via the light-transmissive cured resin layer to obtain an image display apparatus.

Abstract: The present invention is a polishing compound comprising a colloidal solution containing 1˜15 wt. % of silicon oxide particles of 8˜500 nanometer average diameter, wherein said colloidal solution is prepared as a buffer solution which has buffering action between pH 8.7˜10.6 by the addition of one combination selected from groups composed by weak acid and strong base, strong acid and weak base or weak acid and weak base, and logarithms of reciprocal number of acid dissociation constant at 25° C. of said weak acid and/or weak base is 8.0˜12.0.

Abstract: The present invention provides a polishing compound which does not make stain grow on the surface of work-piece comprising, the dispersion containing 1-30 wt. % of metal oxide particles having 8-500 nm average diameter, acid or alkali and salt, and whose pH is 7-12. Desirably said polishing compound is the compound in which water soluble organic solvent is contained. Further, present invention provides edge polishing method and surface polishing method by use of said polishing compound.

Abstract: The present invention is a polishing compound comprising a colloidal solution of silicon oxide to which an alkaline component and an acid component are added in order to have a buffering action, wherein said alkali component is a quaternary ammonium whose carbon number per one molecular is smaller than 12, and said acid component is at least one selected from the group composed by carbonic acid, boric acid and silicic acid.

Abstract: A printer head includes a platen roller, a drive frame movable toward and away from the platen roller, a support block provided on the drive frame, a printing head element secured to the support block to be movable toward and away from the platen roller which it opposes, a pair of freely rotatable guide rollers mounted on the support block and having the printing head element interposed therebetween, a conveying mechanism for conveying a card to be printed on between the printing head element and the platen roller, an ink ribbon which travels while in contact with the pair of guide rollers and the printing head during printing, the ribbon being arranged between the card and the printing head element, a signal source for applying a print signal to the printing head element to cause the element to transfer ink from the ink ribbon to the card, a position adjusting screw provided on the support block to be movable back and forth, the printing head element being positionally adjusted back and forth relative to the

Abstract: A plasticizer composition comprises phthalates of C.sub.9 alcohols obtained by an oxo reaction and a hydrogenation of C.sub.8 olefins which have 3 to 20 wt. % especially 7 to 20 wt. % of olefins having one isobutane skeleton and less than 3 wt. % of olefins having quaternary carbon and more than 90 wt. % of a total of n-octenes, monomethylheptenes and dimethylhexenes and more than 0.8 especially 1.1 to 2.0 of a ratio of a total of n-octenes and monomethylheptenes to dimethylhexenes.

Abstract: A hand type record reading device for magnetized tags includes a fixed member, a moving member capable of movement toward and away from the fixed member while being parallelly aligned with respect thereto, and a tag supporting member fixed to the fixed member. The moving member has plural reading heads adjustable in position according to the thickness of the tag placed on the supporting member, as well as to the position of plural magnetically recorded portion of the tag.

Abstract: Bromine is continuously produced by simultaneously feeding an aqueous solution of bromide or hydrobromic acid and chlorine gas into the top of a contact tower which is separated into an upper reaction section and a lower distillation section, having a gas outlet port therebetween; and feeding steam from the bottom of the tower whereby free bromine formed in the upper reaction port section and free bromine distilled from the lower distillation tower section are recovered through said bromine outlet port, wherein the aqueous solution containing bromide or hydrobromic acid is heated at lower than 80.degree. C in the reaction section and the solution is heated to higher than 90.degree. C in the distillation section.

Abstract: A printing machine for partially magnetized price tickets, labels, etc. which incorporates therein a single magnetic head or a pair of such heads for recording and reading of the magnetized faces of tickets. The magnetic head or heads can be movable horizontally and also be located right under a horizontally movable inking pad of the printing device to go back and forth together therewith. This printing machine can be constructed in a size almost the same as that of a conventional ticket printing machine. The printing machine according to the present invention, due to this mechanism, avoids the problems arising because the printing happens to be different from the recording and also assures the prevention of misrecording.
