在磁带多次迭加生产过程中,排列(1620m—1740m)是相当长的。因此,技工班与仪器组的通讯联络问题成了一个大问题。最近,我们从爆炸点的电话小喇叭受到了启发。采用西安DZ—701型仪器中的电话放大器带小喇叭,较好地解决了这个问题。我队原先爆炸点用的是辽阳电子仪器厂出的DR—9型即发式爆炸机来起爆雷管并用小喇叭(包括计时回路)来与仪器组联络。在改装过程中,我们把爆炸点用的小喇叭的计时回路部分去掉,自制技工班通讯用的小喇叭,采用的小喇叭电话线路如图1。
Arrangement (1620m-1740m) is quite lengthy in tape overlays. Therefore, the issue of communication between the mechanic class and the instrumentation group has become a big issue. Recently, we were inspired by the explosion of the telephone trumpet. Xi’an DZ-701-type instrument using the phone amplifier with a small speaker, a better solution to this problem. The original explosion point of our team used the DR-9 type hair blasting machine from Liaoyang Electronic Instrument Factory to detonate the detonator and used the small horn (including the timing loop) to contact with the instrument set. In the conversion process, we put the explosion point with a small trumpet timing circuit removed, homemade mechanic class communication with a small speaker, using a small speaker phone line in Figure 1.
