    摘要： An agent for stabilizing air content of hydraulic cement compositions includes graft copolymers obtained by a first step in which copolymers with average numerical molecular weight 5000-50000 are obtained by radical polymerization of a mixture of radical polymerizable monomers containing anhydrous maleic acid and monomers of a specified form, together in an amount of 80 molar % or more and at molar ratio of 40/60-60/40 and a second step in which graft copolymers are obtained by a graft reaction of 100 weight parts of the copolymers obtained in the first step and 7-60 weight parts of polyoxyalkylene monoalkylether and/or polyoxyalkylene monoalkenylether with a block addition of a total of 23-70 moles of ethylene oxide and propylene oxide per 1 mole of aliphatic alcohol with 8-20 carbon atoms. A hydraulic cement composition is produced with cement, aggregates, water, a cement dispersant, an agent for controlling air content and contains an agent for stabilizing air content as described above in the amount of 0.001-0.5 weight parts per 100 weight parts of the cement.

    摘要： Polyetherester monomers of a high quality are produced by causing an esterification reaction of polyalkyleneglycol with a closed end of a specified kind which has been refined so as to contain residual free acid by less than 0.03 weight %, as converted to acetic acid, and unsaturated carboxylic acid of another specified kind by using a specified amount of an acid catalyst under a heated and reduced-pressure condition in the absence of solvents and in the presence of p-benzoquinone and/or phenothiazine while distilling away generated water. Cement dispersants are produced by using water-soluble vinyl copolymers obtained by a radical copolymerization reaction between such polyetherester monomers and vinyl monomers.

    摘要： A wire electric discharge machining method for cutting a workpiece (WK) by moving a wire electrode (WR) relative to the workpiece and producing an electric discharge across the wire electrode and workpiece, the method including preparing and entering path data specifying contours to be cut on upper (APL) and lower (BPL) planes of the workpiece, separately preparing and entering such auxiliary data as an amount of wire diameter compensation, workpiece mounting position and guide positions necessary for moving the wire electrode (WR) relative to the workpiece (WK), obtaining relative path data between the workpiece and an upper guide (UG) tensioning the wire electrode as well as relative path data between the workpiece and a lower guide (DG) tensioning the wire electrode by using the path data and the auxiliary data, and taper cutting contours commanded on the upper and lower planes of the workpiece by moving the upper and lower guides relative to the workpiece using both path data.

    摘要： A wire cut electric discharge machining condition setting system including cursor shift push button switches for selecting with a cursor one of the machining conditions displayed on a screen at a CRT display unit, numerical push button switches for setting values of the selected machining conditions, and increment and decrement push button switches for continuously updating the preset values of the machining conditions all arranged in a wire cut electric discharge machine. The value of the machining condition selected with the cursor is set by the numerical push button switches and is updated by the increment and decrement push button switches.
