    • A safe and versatile recombinant DNA cloning vector having at least two functionally different replication origins selected independently from the group consisting of a replication origin functional in Bacillus subtilis, a replication origin functional in Escherichia coli and a replication origin functional in Pseudomonas aeruginosa, and at least one DNA segment which provides resistance against at least one antibiotic after introduction into susceptible host cells. The origin for replication origin functional in Bacillus subtilis can be a restriction fragment of a plasmid of Gram positive bacteria, and that Escherichia coli or Pseudomonas aeruginosa can be a restriction fragment of a plasmid of Gram negative bacteria, e.g. a restriction fragment of plasmids pMS 140-1 or pMS 71.

    • A load driving circuit causes a driving current to flow through a load, such as a reel motor, an audio load or the like through the collector and emitter of a drive transistor. A load voltage which changes according to changes in the driving current is obtained at a point of connection between the drive transistor and the load. On the basis of the load voltage, an offset voltage having a predetermined constant value is generated in a power supplying circuit so as to cancel a change in the load voltage. The offset voltage is supplied as driving source output to the drive transistor so as to prevent the generation of excess heat in the drive transistor even if the driving current changes.
    • 负载驱动电路通过驱动晶体管的集电极和发射极使驱动电流流过诸如卷轴电机,音频负载等的负载。 在驱动晶体管和负载之间的连接点处获得根据驱动电流的变化而变化的负载电压。 基于负载电压,在供电电路中产生具有预定常数值的偏移电压,以消除负载电压的变化。 偏移电压作为驱动源输出被提供给驱动晶体管,以便即使驱动电流改变也能防止驱动晶体管中产生过多的热量。
