Abstract: A semiconductor device includes a first transistor and a protection structure. The first transistor includes a gate electrode, a gate dielectric disposed on the gate electrode, and a channel layer disposed on the gate dielectric. The protection structure is laterally surrounding the gate electrode, the gate dielectric and the channel layer of the first transistor. The protection structure includes a first capping layer and a dielectric portion. The first capping layer is laterally surrounding and contacting the gate electrode, the gate dielectric and the channel layer of the first transistor. The dielectric portion is disposed on the first capping layer and laterally surrounding the first transistor.

Abstract: A container feeding device includes a casing and first and second latch members. The casing defines a lower retaining space for receiving a plurality of containers that are stacked on one another. The first latch member is operable to enter the lower retaining space for supporting a bottommost container, or leave the lower retaining space to release the bottommost container. The second latch member enters the lower retaining space to support a second bottommost container when the bottommost container is released by the first latch member.

Abstract: A tool set includes a tool holder, a tool and a tool rack. The tool has a groove unit. The tool holder has a latch unit that engages the groove unit. The tool rack includes a rack body and a blocking member. When the tool holder is moved away from the rack body after the tool is moved into the rack body by the tool holder and after the blocking member moves to a blocking position, the tool is blocked by the blocking member so that the latch unit is separated from the groove unit and that the tool holder is separated from the tool.

Abstract: A mounting frame for being mounted with either one of first and second screwdrivers, includes a main frame, a mounting seat, and first and second mounting plates. The mounting seat has a plate attachment hole set. The first mounting plate has a first seat attachment hole set operable to be connected to the plate attachment hole set, and a first driver attachment hole set for the first screwdriver to be attached thereto. The second mounting plate has a second seat attachment hole set operable to be connected to the plate attachment hole set, and a second driver attachment hole set for the second screwdriver to be attached thereto.

Abstract: Provided is an underground pipe leak detection system, including a sensing device, a storage device, and a processing device. The sensing device is used for collecting a voice signal from an underground pipe during a time period. The storage device is used for storing a voice dataset, and storing the voice signal transmitted by the sensing device. The processing device may access the storage device. The processing device is configured to execute the following operations: training a classification model using the voice dataset; extracting features of the voice signal; inputting the features of the voice signal into the classification model that has been trained to determine if there is a leak in the underground pipe.
