    • A power system having a power saving mechanism includes a voltage regulator, a power input module, and a switching signal generation unit. The voltage regulator performs a regulation operation on a first voltage for generating a second voltage. The power input module includes a transformer, a rectifying unit, a switch, and a switch control unit. The rectifying unit together with the transformer is put in use for converting an input voltage into the first voltage. The switch is employed to control a current flowing through the primary winding of the transformer. The switch control unit generates a control signal for controlling the switch according to a switching signal. The switching signal generation unit is utilized for generating the switching signal to disable the switch control unit during an energy transfer disable interval so as to decrease the first voltage from a first predetermined voltage to a second predetermined voltage.
    • 具有省电机构的电力系统包括电压调节器,电力输入模块和开关信号生成单元。 电压调节器对第一电压执行调节操作以产生第二电压。 电源输入模块包括变压器,整流单元,开关和开关控制单元。 整流单元与变压器一起被用于将输入电压转换成第一电压。 该开关用于控制流过变压器初级绕组的电流。 开关控制单元根据开关信号产生用于控制开关的控制信号。 切换信号生成单元用于产生切换信号,以在能量传递禁止间隔期间禁止开关控制单元,从而将第一电压从第一预定电压降低到第二预定电压。

    • A gas leak detection apparatus includes a main body, a magnetically operated valve, a magnetically exciting device, a pressure sensing device, and a pressure detector. Thus, if the pressure detector detects that the gas leak happens to the pipe located at the rear side of the gas regulator, the control circuit board drives the magnetically exciting device to produce a magnetic force to drive the magnetically operated valve to close the conduit of the valve chamber and the outlet of the main body so as to interrupt the gas flow, thereby preventing the gas from entering the pipe located at the rear side of the gas regulator so as to provide a safety effect to the user.
    • 气体泄漏检测装置包括主体,磁力操作阀,磁力激励装置,压力感测装置和压力检测器。 因此,如果压力检测器检测到气体泄漏发生在位于气体调节器的后侧的管道上,则控制电路板驱动磁激励装置以产生磁力,以驱动磁力操作的阀来关闭 阀室和主体的出口,以便中断气流,从而防止气体进入位于气体调节器后侧的管道,从而为使用者提供安全的效果。
