Abstract: A paper pickup mechanism includes a mechanical frame, a pickup roller module, a feeding roller module, a driving device, a separation roller module and an energy storage element. The mechanical frame has a platform. The pickup roller module is pivoted to and connected to the mechanical frame. The feeding roller module is pivoted to and connected to the mechanical frame. The driving device is mounted to the mechanical frame. The separation roller module is pivoted to and connected to the mechanical frame. The energy storage element is mounted between the mechanical frame and the separation roller module. When the separation roller module rotates together with the feeding roller module in a forward direction, the energy storage element accumulates energies. When more than one piece of paper is fed into the paper pickup mechanism, the energy storage element releases the energies.

Abstract: A rotary paddle level switch has a housing, a driving unit, two switches, a resilient member, a clutch, a transmission shaft, and a propeller. A resilient clip of the clutch holds a non-circular actuation section of the transmission shaft. When the driving unit drives the clutch to rotate, the transmission shaft and the propeller are driven by the clutch. When the propeller is rapidly rotated by suddenly exerting an excessively large external force thereon, as the resilient clip holds the transmission shaft by elastic force, the fast rotating transmission shaft removes itself from the holding of the resilient clip and is rotated without driving the resilient clip to rotate, thereby avoiding the transmission of the external force and damage to the driving unit. As the clutch just needs a clutch stand and a resilient clip to achieve the foregoing function, the level switch is structurally simple and relatively inexpensive.

Abstract: A sensing device can detect material depth, liquid-level, and temperature. The sensing device has a probe, a control module, a volume sensing module, a thermal sensing module, an output module, and a power module. The probe has two material electrodes connected to the volume sensing module and a thermal electrode connected to the thermal sensing module. A rated voltage is applied at the material electrodes based on radio frequency admittance. A current deviation of the material electrodes is obtained by the volume sensing module, and calculated via the control module by material characteristics to obtain a correct storage amount of material. A temperature at each material depth is correctly detected by the thermal electrode. Steel cable is used as the material of the material electrodes of the probe to detect material depth or liquid level with high impact resistant ability.

Abstract: A honeycomb heat dissipating apparatus made of a composite metal material includes honeycomb cells that are integrally formed by vacuum die casting, and continuous convex and concave distal surfaces disposed around the periphery of the heat dissipating apparatus, and an adjacent surface of each cell is a thin surface, and the heat dissipating apparatus can be in a standalone mode, or combined with other heat dissipating apparatuses. One or more honeycomb heat dissipating apparatuses can be installed on a circuit board or an electronic component of a lamp or an electric appliance, such that the heat dissipating apparatus can dissipate heat quickly by the honeycomb cells without occupying much space. The invention can increase the heat dissipating area for a faster heat dissipating effect and change the stylish appearance to achieve the aesthetic effect.
