    Abstract: A fixing device for an LCD module and a faceplate includes a frame having one side fixing an LCD module and another side provided with plural fixing plates respectively bored with an elongated insert hole. A circuit board is secured at a rear side of a faceplate and provided with plural locking plates corresponding with the fixing plates so that the fixing plates of the frame can be respectively secured with the locking plates. Thus, relative positions of an LCD module and a faceplate can be adjusted and hence LCD modules different in thickness can be firmly fixed with a faceplate and the surface of the LCD module can be stably kept flush with the surface of the faceplate.

    Abstract translation: 用于LCD模块和面板的固定装置包括一个框架，其一侧固定LCD模块，另一侧设置有分别钻有细长插入孔的多个固定板。 电路板固定在面板的后侧，并设置有与固定板对应的多个锁定板，使得框架的固定板可以分别用锁定板固定。 因此，可以调节LCD模块和面板的相对位置，因此可以用面板牢固地固定不同厚度的LCD模块，并且可以将LCD模块的表面稳定地保持与面板的表面齐平。

    Abstract: A real-time-calibration circuit for multiple CPUs includes the CPUs for communication, for control and for acting as a panel board. The CPUs each have a real-time clock built therein. The CPU for communication is connected with an external real-time clock, and only the external real-time clock is connected with a battery. Through the CPU for communication, a standard time is obtained from an external network and provided to the external real-time clock for time calibration. Then a calibration value generated from the time calibration is fed back to the CPU for communication to be used by the real-time clock of the CPU for communication and the real-time clocks of the other CPUs, so as to prevent the CPUs from interfering communication during time calibration, and reduce the need of power and of batteries, thereby saving energy and costs and being friendly to the environment.

    Abstract: A human-machine interface module structure includes a circuit module, a retaining seat, and a liquid crystal panel. The circuit module is fixedly connected to a frame. The circuit module includes a first circuit board and a second circuit board that are stacked in parallel. The first circuit board is fixedly connected to an inner side of the frame. The second circuit board is located behind the first circuit board. The first circuit board is electrically connected to the second circuit board. The retaining seat is parallel with and connected to the first circuit board. A front of the retaining seat has an accommodating space. The liquid crystal panel is accommodated in the accommodating space. The liquid crystal panel is electrically connected to the first circuit board through a flat flexible cable. The human-machine interface module structure is small in size and is easy to assemble and durable.

    Abstract: A high power density DC-AC power inverter includes a casing corresponding to a rack. The casing has air inlets and air outlets arranged in a honeycomb shape and a fan unit. The casing is provided with two choke coils and a heat sink therein. The heat sink includes fins facing downward. A plurality of power elements are laterally provided on top of the heat sink. The heat generated from the power elements can be conducted to the fins of the heat sink quickly. The fan unit guides the outside air to the heat sink and the choke coils through the air inlets, and the heat is smoothly expelled out of the casing through the air outlets of the casing. The power inverter in a high density configuration still has a good heat dissipation effect.
