    • PURPOSE:To inspect the propriety of muPG of additional functions and the structure of logic circuit, by comparing the data designating muPG of specific function with the data representing the specific functions of the logic circuit, in the computer of microprogram muPG control. CONSTITUTION:One of the output pins of the package PKG1 constituting the additional functions of computer are connected to ground, and the additional function signal 3 is at L level with PKG1 present, and at H level with that absent. In a computer having the capacity of control memory 5 of 4K words, if the muPG of additional function is written in the final 1K words, the upper rank 2-bit of the address register 6 is the address signal 8 and it is compared with the signal 3 at the comparison circuit 4. When the content of the register 6 designates the muPG of additional function, if no additional function PKG is present and the signal 3 is at H level, the structure error signal 9 is outputted from the circuit 4. As a result, the execution of muPG is stopped, allowing to prevent malfunction.

    • A standard incandescent light circuit comprises a fixed wire from the active (10) side of an alternating current source to a light control switch located conveniently on a wall, which is connected to the switched active side of the light by another fixed wire from the wall mounted switch to the light the circuit being completed when the light is connected to the neutral side of the alternating current source. The invention replaces the light control switch with at least two master switches (51, 52) and in one embodiment by means of selectively conducting at least one of the polarities of the alternating current source the master switches selectively controls at least two loads. In one embodiment diodes (D5, D6) are used to selectively pass the positive or negative voltage half cycles of the alternating current source, and a control circuit (20) detects which master switch has changed state and via slave relay means switches (RY1-1, RY2-1) at least one of the loads independent of the other.
    • 标准白炽灯电路包括从交流电源的有源(10)侧到便于在壁上定位的光控制开关的固定电线,该光控开关通过来自墙壁的另一固定电线连接到光的开关主动侧 当光连接到交流电源的中性线时,安装的开关到达电路正在完成。 本发明用至少两个主开关(51,52)代替光控开关,并且在一个实施例中,通过选择性地传导交流电源的至少一个极性,主开关选择性地控制至少两个负载。 在一个实施例中,二极管(D5,D6)用于选择性地通过交流电源的正或负电压半周期,并且控制电路(20)检测哪个主开关已经改变状态,并且经由从属继电器装置开关(RY1- 1,RY2-1)至少一个负载独立于另一个。
