  • Patent number: 12243762
    Abstract: A door locking mechanism and semiconductor container using the same include door panel, cover, and locking module. The door panel has a first stop structure. The cover and the door panel define an accommodating space for receiving the locking module. The locking module includes rotating member, holding member, and elastic member. The elastic member is disposed on the holding member and has a second stop structure near the first stop structure. The elastic member is disposed between the holding and the rotating member. The elastic member is compressed when a force is applied to the holding member, and the second stop structure detaches from a limitation state with the first stop structure for allowing a rotating operation of the rotating member. The elastic member elastically restores when the force is removed, and the second stop structure returns to the limitation state for limiting the rotating operation.

  • Patent number: 11212122
    Abstract: A power source device coupled to a power device includes an output port and a controller. When the output port is coupled to a connection cable, the controller is activated to generate a handshake signal, so as to communicate with the power device. When it is determined that the power device is able to be powered according to the handshake signal, the controller controls the power supply device to power the power device through the connection cable. When the connection cable is not coupled to the output port, the controller is deactivated and thus the handshake signal is not generated.
