本文扼要地介绍了我所研制成功的J-Ⅱ型记忆磁心自动选择机,并给出了该自动机的主要技术指标。J-Ⅱ型磁心自动选择机对磁心读出信号波形进行多点选通测试,因此明显地提高了对磁心电性能一致性的描述能力。本自动机可按磁心工作域法测试磁心进而有助于扩大磁心板的工作范围。本自动机研制成功后试测二百多小时证明性能稳定可靠。 This article briefly introduced my successful J-Ⅱ type memory core automatic selection machine, and gives the main technical indicators of the automatic machine. J-Ⅱ type of core automatic selection machine core readout signal waveform for multi-strobe test, thus significantly improving the consistency of the description of the performance of magnetic core capabilities. The automatic machine can test the core according to the core work area method and then help to expand the working range of the core board. After the successful development of this automatic machine more than 200 hours test proved stable and reliable.
