    • Provided is a method of producing a low viscosity phenol-modified aromatic hydrocarbon formaldehyde resin (C), including subjecting an aromatic hydrocarbon formaldehyde resin (A) and a phenol (B) to condensation reaction under the presence of an acid catalyst. The method includes: terminating, when a reaction mixture has a viscosity at 25° C. of 200 to 1,500 mPa·S, the condensation reaction by adding an inorganic basic compound and/or a tertiary amine compound having a boiling point of 300° C. or more; and distilling and removing the phenol (B) unreacted and a low boiling component after termination of the condensation reaction, whereby there can be produced a low viscosity phenol-modified aromatic hydrocarbon formaldehyde resin which is kept in a liquid state and contains small amounts of unreacted phenols, and in which increase in viscosity is small even after removal of low boiling components.
    • 本发明提供一种低粘度苯酚改性芳香族甲醛树脂(C)的制造方法,其特征在于,在酸催化剂的存在下,使芳香族甲醛树脂(A)和苯酚(B)进行缩合反应。 该方法包括:当反应混合物在25℃下的粘度为200至1,500mPa.S时,终止通过加入沸点为300℃的无机碱性化合物和/或叔胺化合物的缩合反应 。 或者更多; 并在缩合反应结束后蒸馏除去未反应的苯酚(B)和低沸点成分,由此可以制备保持液态的低粘度苯酚改性芳香族甲醛树脂,并含有少量未反应的 即使在除去低沸点组分之后,粘度的增加也很小。

    • In a multi-processor system constituted by a processor such as a CPU and a DSP, in which the processor and the DSP have an external memory and a bus as shared resources and the DSP carries out a process in response to a processing request from the processor, a monitoring step for status of use includes a step of monitoring the status of use of the DSP, and when contention information obtained in the monitoring step for the status of use indicates frequent uses, an altering step for software process appropriately alters a software processing method to be executed, and switches the corresponding process to an equivalent process so that it becomes possible to avoid bus contention, and consequently to prevent a reduction in the processing speed.
