    • In a computer having a program including a first type of instruction and a second type of instruction, a program memory has a first area for storing the first type of instruction and a second area for storing the second type of instruction. An address code is supplied from a program counter to the program memory, which thereby produces an instruction code stored at the addressed memory location. A control unit is responsive to the instruction code from the program memory for producing a control signal for controlling the operation of the computer. A protection circuit is provided for preventing execution of the first type of instruction when the address code output from the program counter does not designate any memory location in the first area.
    • 在具有包括第一类型指令和第二类型指令的程序的计算机中,程序存储器具有用于存储第一类型指令的第一区域和用于存储第二类型指令的第二区域。 从程序计数器向程序存储器提供地址代码,从而产生存储在所寻址的存储器位置的指令代码。 控制单元响应于来自程序存储器的指令代码,用于产生用于控制计算机的操作的控制信号。 当从程序计数器输出的地址代码未指定第一区域中的任何存储器位置时,提供保护电路以防止执行第一类型的指令。

    • This invention relates to a process for preparing high-purity aromatic oligomers by effectively separating an organic layer containing aromatic oligomers or the reaction products of a polycyclic aromatic compound with formaldehyde from an aqueous layer containing an acid catalyst in a simplified manner, hitherto regarded difficult to accomplish, and obtaining high-purity aromatic oligomers from the organic layer containing a reduced amount of impurities. In separating the aqueous layer containing the acid catalyst and the organic layer containing the oligomers from the reaction mixture formed by the condensation of a polycyclic aromatic compound and formaldehyde, the emulsion phase is broken by adding a nonionic or cationic surfactant in an effective amount and an alkali in an amount sufficient to neutralize 1–70% of the acid in the acid catalyst, the organic and aqueous layers are separated and the aromatic oligomers are recovered from the organic layer.
    • 本发明涉及一种制备高纯度芳族低聚物的方法,该方法通过以简单的方式从含有酸催化剂的水层中有效地分离含有芳族低聚物的有机层或多环芳族化合物与甲醛的反应产物,至今被认为难以 从含有少量杂质的有机层中获得高纯度芳族低聚物。 在将含有酸催化剂的水层和含有低聚物的有机层从由多环芳族化合物和甲醛缩合形成的反应混合物中分离时,通过加入有效量的非离子或阳离子表面活性剂和 碱的量足以中和酸催化剂中的1-70%的酸,分离有机层和水层,并从有机层中回收芳族低聚物。
