Abstract: A vapor chamber with a support structure is provided. The vapor chamber with the support structure includes a first plate, a second plate spaced apart from the first plate, and multiple support elements fixed between the first and second plates. On an outer surface of any of the first plate or the second plate, laser welding is performed on positions corresponding to the support elements so as to join the support elements to the first and second plates and to form weld ports on the outer surface of any of the plates. The invention solves the problem of fixing the support structure inside the thin vapor chamber, and therefore mass production can be realized.

Abstract: A motor includes a rotor and a stator. The rotor comprises a rotating shaft and an impeller. The impeller couples with the rotating shaft and has a hub. The hub has an outer surface, an inner surface, a plurality of first through holes and a plurality of second through holes. The first through holes are disposed nearer the rotating shaft than the second through holes. The stator comprises a silicon steel sheet and a bearing assembly. The silicon steel sheet has an annular portion and a plurality of protruding portions. The rotating shaft couples with the bearing assembly and penetrates within an inner hole of the annular portion. Each protruding portion is extended outward from the annular portion and has an extending length. The distance between the first through hole and the nearest second through hole is in a range of 0.3 to 1.2 times of the extending length.

Abstract: A case for receiving at least one electronic device is provided, including a housing, a hinge, a locking member, and a cover. The housing has an accommodating space and an opening communicated with the accommodating space. The hinge is slidably connected to the housing. The cover has an upper side, a lower side, and an outer surface. The lower side is pivotally connected to the hinge. When the locking member affixes the upper side to the housing and the hinge is in a first position relative to the housing, the cover is disposed between an environment space and the accommodating space, and the outer surface faces the environment space. When the locking member is released and the hinge moves to a second position relative to the housing, the cover leaves the position between the environment space and the accommodating space, and the outer surface faces the environment space.

Abstract: A power drive circuit includes a power conversion module, a plurality of gate drivers, a waveform processing unit, a control unit, a weighting unit, and a comparator. Each gate driver includes a drive resistance setting value. The waveform processing unit outputs a current absolute value waveform of an AC power. The weighting unit generates a trigger voltage. When the comparator determines that the current absolute value waveform is greater than the trigger voltage, the comparator outputs a slew rate control signal to each of the gate drivers. When the gate driver receives the slew rate control signal, each of the gate drivers decreases the drive resistance setting value of the gate driver.

Abstract: An insulation resistance detection circuit is coupled to a positive end and a negative end of a DC power source, and is used to detect a positive insulation resistance between the positive end and a ground point and detect a negative insulation resistance between the negative end and the ground point. A detection unit sets a first estimated resistance and a second estimated resistance, and acquires a first voltage based on turning on the switch and acquires a second voltage based on turning off the switch. The detection unit calculates a third voltage and a fourth voltage according to the first estimated resistance and the second estimated resistance so as to detect the positive insulation resistance and the negative insulation resistance when the third voltage is equal to the first voltage and the fourth voltage is equal to the second voltage.
