摘要： A phenolic resin composition comprises a mixture of 100 parts by weight of a phenol aralkyl resin and 5 to 60 parts by weight of a novolak type phenolic resin having a content of binuclear components of not more than 10% by area, and a content of trinuclear components of not less than 50% by area and a sum content of tri- and tetra-nuclear components of 75% by area based on the total novolak phenolic resin except for the binuclear components, and an epoxy-cured product obtained by curing an epoxy resin while using the phenolic resin composition as set forth in claim 1 as a curing agent. The phenolic resin composition has a low viscosity and, when it is used as a curing agent for epoxy resins, the resulting epoxy-cured product has a low water absorption rate, is excellent in resistance to moisture and has a high glass transition temperature as compared with the cured product obtained using a novolak type phenolic resin as a curing agent.

摘要： When recording information, a write switching current of a write signal is directed through a coil of a magnetic head, whereby the information corresponding to the write signal is to be recorded on a magnetic recording medium. Hence, a back electromotive voltage is inevitably produced at the coil of the magnetic head. Based on the level of this back electromotive voltage, the quality of the magnetic head can be detected. In this case, by use of a synchronizing circuit, the detected timing of the back electromotive voltage is synchronized with a switching timing of the write switching current. Due to this synchronizing circuit, the back electromotive voltage is detected only at the switching timing of the write switching current, whereby it becomes possible to detect the back electromotive voltage, regardless of noise. Thus, it is possible to detect the quality of the magnetic head with accuracy.
摘要翻译： 当记录信息时，写入信号的写入开关电流被引导通过磁头的线圈，由此将与写入信号相对应的信息记录在磁记录介质上。 因此，磁头的线圈不可避免地产生反向电动势。 根据该反电动势的电平，可以检测磁头的质量。 在这种情况下，通过使用同步电路，检测到的反电动势电压的定时与写入开关电流的切换定时同步。 由于该同步电路，仅在写入开关电流的切换定时检测反向电动势，所以无论噪声如何，都可以检测反电动势电压。 因此，可以精确地检测磁头的质量。
