    • A smart peripheral device includes a first interface which connects to the printer output port of a first personal computer and receives first printer data of a first printer format from the printer output port of the first personal computer. The smart peripheral device also includes a second interface for connecting to the I/O port of a second computer device containing predetermined application software. The smart peripheral automatically translates the first printer data into a general purpose import file which is compatible with the application saoftware of said second computer device, and outputs the general purpose import file via the second interface.

    • A parallelized power supply system including a plurality of switching power supplies each having a circuit for limiting rush current generated when a main switch is turned on. This system can be installed in an apparatus which requires the functions such as power uninterrupted operation and live wire insertion/dismount. Each switching power supply has another power supply for driving the rush current limiter circuit and a relay circuit for supplying relay driving current and making a connection of relay contacts after a predetermined time lapse after the operation start of the switching power supply. An a.c. power is supplied via the relay contacts to each switching power supply. The relay driving time set in the rush current limiter circuit is different for each switching power supply. Accordingly, concentration and excess of rush current when the relay is driven can be suppressed, and sparks at contact pins of a connector to be otherwise generated when the switching power supply is mounted on the connector, can be eliminated so that radiation noises and connector breakage can be avoided. Each of the switching power supplies connected in parallel has a current detecting resistor connected between the low voltage side of a load and the low voltage side of a voltage regulator d.c. output, and at least one operational amplifier for detecting a change in the d.c. output, the negative power supply terminal of the operational amplifier being connected to the current detecting resistor at its one end on the load side.
    • 一种并联电源系统,包括多个开关电源,每个开关电源具有用于限制当主开关导通时产生的冲击电流的电路。 该系统可以安装在需要诸如电源不间断操作和带电线插入/卸载等功能的设备中。 每个开关电源具有用于驱动冲击电流限制器电路的另一个电源和用于在开关电源的操作开始之后的预定时间经过之后提供继电器驱动电流和继电器触点的连接的继电器电路。 一个 电源通过继电器触点提供给每个开关电源。 在冲击电流限制电路中设置的继电器驱动时间对于每个开关电源是不同的。 因此,可以抑制继电器驱动时的集中和超过冲击电流,并且可以消除当开关电源安装在连接器上否则产生的连接器的接触引脚上的火花,使得辐射噪声和连接器断裂 可以避免。 每个并联的开关电源具有连接在负载的低电压侧和电压调节器d.c.的低压侧之间的电流检测电阻器。 输出,以及用于检测直流电的变化的至少一个运算放大器。 运算放大器的负电源端在负载侧的一端连接到电流检测电阻。
