Abstract: A fine atomic clock includes a particle source, an MW filter, an atomic gun, a Magneto-MW Trap (MMT) unit, an energy injection unit, and a probing unit. The particle source emits particles. The MW filter receives the particles and generates a plurality of coherent MW of particle beams. The particle beams forms a virtual space-time lattice in an enclosed space. The atomic gun emits a sample. The MMT unit utilizes a magnetic field to trap the sample in the virtual space-time lattice, and utilizes the particle beams to cool down the sample. The sample corresponds to fermions or molecules. The energy injection unit injects energy into the sample to activate the sample into an excitation state. The probing unit activates emission of the sample. An emission frequency of the sample corresponds to a characteristic emission frequency of the sample, and the emission frequency generates a standard time signal.

Abstract: A detaching mechanism for a detachable module is provided. The detaching mechanism includes an engaging component and a driving component.

Abstract: A circuit board device includes a fixing member and a circuit board having a first hole. The fixing member includes abase having a second positioning portion and an opening, a first fixing component and a pillar structure having a first pillar body and a positioning pillar extending downward from the first pillar body and having a first positioning portion and a clamping portion. The clamping portion clamps the circuit board with the first pillar body when the first positioning portion is engaged with the first hole. The base is disposed in the first hole and abuts against the positioning pillar when the second positioning portion hooks the first hole and the opening is engaged with the positioning pillar. The first fixing component is detachably inserted into the pillar structure for clamping a first interface card with the first pillar body.

Abstract: A host casing of an electronic device includes a housing, a filler panel, and a disassembly and assembly structure. A front side of the housing has an opening. The dummy cover is disposed in the opening of the housing. The disassembly and assembly structure is disposed inside the housing. In a first state, the disassembly and assembly structure buckles with the dummy cover, thereby fixing the dummy cover. In a second state, the disassembly and assembly structure releases the dummy cover, and simultaneously pushes the dummy cover out of the opening. Therefore, the replacement action between the dummy cover and a pluggable device can be effectively simplified, so that maintenance personnel can easily assemble or disassemble the dummy cover without the assistance of additional tools.
