    • This invention relates to a process for the selective ortho-alkylation of a phenolic compound having at least one ortho-positioned hydrogen atom by catalytically reacting the phenolic compound with an alcohol in the vapor phase. In this process, the reaction of the phenolic compound with the alcohol is carried out at a temperature of from 300.degree. to 550.degree. C. in the presence of a catalyst containing manganese oxide, silicon oxide and one or more additives selected from group (A) consisting of germanium oxide, tin oxide and lead oxide, or a catalyst containing manganese oxide, silicon oxide, one or more additives selected from the aforesaid group (A), and one or more additives selected from group (B) consisting of alkali metal oxides and alkaline earth metal oxides. The catalyst used in this invention exhibits not only excellent catalytic activity in the selective ortho-alkylation of phenols, continuous stability of the activity, good shapability, and good mechanical strength but also effective utilization of alcohols.

    • When performing the processing while changing the position and the posture of the tool relative to the work, if the speed of the tool tip point relative to the work is regularly controlled while greatly changing the tool posture, the speed of each driving shaft of the machine is increased, whereby the interference may be generated. In order to solve the problem, in the numerical controller which obtains the position of each driving shaft of the machine performing the determination of the feeding speed, the interpolation and the coordinate conversion according to the relative instruction path and the instruction speed of the tool tip point relative to the work instructed to the processing program, when determining the feeding speed, the reference point is provided on the tool or the table, the translation speed of the reference point viewed from the mechanical coordinate system is set to the observation target speed, the reference feeding speed is obtained so that the observation target speed is a predetermined reference speed, and the smaller of the reference feeding speed and the instruction feeding speed is set to the feeding speed.
    • 当在改变工具相对于工件的位置和姿态的同时进行处理时,如果在大大改变工具姿势的同时,相对于工件的刀尖点的速度被定期地控制,则机器的每个驱动轴的速度 从而可能产生干扰。 为了解决这个问题,在获得进给速度确定的机器的每个驱动轴的位置的数值控制器中,根据相对指令路径和刀尖指令速度的插值和坐标转换 相对于处理程序指示的工作点,当确定进给速度时,将参考点设置在工具或工作台上,将从机械坐标系观察到的参考点的平移速度设定为观察目标速度, 获得基准进给速度,使得观察目标速度为预定的基准速度,并且将基准进给速度和指令进给速度的较小值设定为进给速度。
