专利汇可以提供Fixed time control system of microcode专利检索,专利查询,专利分析的服务。并且PURPOSE:To control a feeding mechanism for documents, etc., with high precision by programming the control logic of a feedback loop, holding the number of steps constant, and performing fixed-time control over a sampling period, manipulated variable output, etc. CONSTITUTION:When an address is increased by an incrementer 3 by inputting a clock, areas of digits 2 -2 of a microprogram memory 2 are accessed to read microcodes, and an arithmetic logical element 1 performs operations by the specification of the microcodes. This system has four modes; and microcodes of a main routine and a subroutine for position control under which a speed is varied following up a target speed are stored in addresses 0-127 and 128-255, and microcodes of a main routine and a subroutine for stop control are stored in addresses 256-511. Further, microcodes of a main routine and a subroutine for open loop control are stored in addresses 512-767, and microcodes are stored in addresses 768-1023. Then, four kinds of processing are performed by the output of a latch 4 according to instructions from a high-order control part.,下面是Fixed time control system of microcode专利的具体信息内容。
