Abstract: A shearing tool includes a first and second shearing portion and a retaining mechanism. The first and second shearing portions are pivotally engaged with each other. The first and second shearing portions are movable relative to each other between a first relative position and a second relative position. The retaining mechanism includes a first retaining portion and a second retaining portion selectively engagable with each other to retain the first and second shearing portions in the second relative position. The first retaining portion is formed on a first retaining member which is pivotally engaged with the first shearing portions. The second retaining portion is formed on a second retaining member which is connected to the second shearing portion.

Abstract: A pair of snips with one-hand-operable lock device includes a first and second grip disposed side by side, a pair of cutting members pivotally connecting with each other and including one cutting member connecting to the first grip and the other cutting member connecting to the second grip respectively, and a lock device including a structural member pivotally connecting to the first grip and including a first structural section as a user control end disposed at one of two opposite ends of the structural member, a second structural section as a locking end disposed at the other end of the structural member, and a third structural section disposed between the first and second structural sections and including a pivot extending therefrom and engaging with the first grip.

Abstract: An optical plate includes a substrate having a light emitting surface, a rear surface opposite to the light emitting surface, and a plurality of microstructures that cooperatively define the light emitting surface and each of which parallelly extends in a light traveling direction. Each of the microstructures includes first and second convex portions and a concave portion disposed between and interconnecting the first and second convex portions, and two adjacent ones of the microstructures are connected. Intersections between the microstructures cooperatively define an imaginary plane, and a lowest point of the concave portion is disposed at one side of the imaginary plane opposite to the rear surface of the substrate.

Abstract: A tool holder includes a foldable plastic sheet being folded and configured to include a hanging end and a holding end. The hanging end and the holding end integrally form a one piece structure. The holding end having a first edge, a second edge, a first lateral edge, and a second lateral edge, with the first and second edges and the first and second lateral edges delimiting a circumferential periphery of a receiving space in which the first and second edges are opposite each other and the first and second lateral edges are opposite each other and respectively extend from two lateral sides of the first edge to two lateral sides of the second edge. A joint edge is distal the first lateral edge extending therefrom and adhered to the second lateral edge.

Abstract: A time sectionalized demodulator for pulse-code modulated (PCM) signal is demodulated by counting the number of carrier cycles including noise cycles to compare with a predetermined minimum number N within a time slot for a high voltage level output. When the counted number exceeds the predetermined number N, a high voltage level is outputted from the comparator. The carrier cycles including noise cycles is modulated and then sectionalized by time slots. By comparing the modulated pulse number with the preset number N within a time slot to filter out noise signal which yields pulses greater than N for high voltage level and to filter out noise signal which yields pulses less than N for low voltage level.

Abstract: A support frame for an ice-storing tank for an air conditioner with an ice-storing mode includes plural rods formed in a radial direction, and each rod has plural grooves for fitting therein a spiral hollow tube of one of plural spiral tube units. Further a connector is provided in the center of the base, having plural insert vertical grooves formed in a radial direction to connect to inner ends of the rods of the support frame. All the connectors are piled up one by one to connect with all the rods of the spiral tube units, increasing combining and supporting strength.

Abstract: An ice-storing tank for an air conditioner with an ice-storing tank includes a temperature-preserving tank and a spiral pipe set positioned in the tank. The spiral pipe set consists of a bottom base, a plurality of upright long posts spaced around an outer circumferential edge of the bottom base, and a plurality of independent spiral pipe units orderly placed on the bottom base. Each spiral pipe unit consists of supporting rods radially arranged and a spiral pipe supported on the supporting rods. The outer end of each supporting rod is fixed with the upright long post, and two ends of each pipe have a joint. A vertical inlet pipe and a vertical outlet pipe are provided to stand just outside the bottom base, having a plurality of connecting mouths to connect to the joints of each pipe and their upper ends extending out of the temperature-preserving tank to function as an inlet and an outlet for freezing liquid.
