Abstract: An exemplary embodiment of the present disclosure illustrates a cable assembly. The cable assembly comprises a first cable and a second cable. The first cable has two contacts at both ends thereof, and the second cable has two contacts at both ends thereof. The first cable and second cable are used for transmitting a first signal and a second signal respectively. A differential signal is formed by the first signal and the second signal, and at least one of those contacts is an adjustable contact. The adjustable contact adjusts an electrical length of the first cable or the second cable to control a phase error between the first signal and the second signal.

Abstract: A terminal structure for a coaxial cable includes a casing having a passage defined axially therethrough and a plurality of stops extend from an inner periphery of the passage. An axle has a connection end and a plurality of protrusions extend from an outer periphery of the connection end. The connection end of the axle is inserted into the passage and the protrusions are stopped by the stops. A non-conductive material is filled in a partition of the passage and connects the axle and the casing. The non-conductive material is filled in the partition of the passage by way of injection.

Additionally, the PMP is provided with more functions, such as receiving a real-time audio-visual data through wireless transmission, or being used for shooting as a digital camera, or functioning as a cell phone, through plugging a function extension card therein.

Abstract: A method for manufacturing a separator having a high ionic conductivity is proposed, in which at least a composite cloth comprising a polypropylene inner layer and a polyethylene outer layer, a polypropylene cloth or a polyethylene cloth is chosen as the substrate. Next, the substrate surface is rinsed to remove impurities. The substrate is then baked. Subsequently, sulfonation is performed to the substrate using concentrated sulfuric acid. The substrate is then rinsed using DI water until the DI water that has rinsed the substrate has a pH value of 6˜7. Finally, the substrate is baked. A separator having a high ionic conductivity can thus be obtained.

Abstract: This invention relates to a method for fabricating solid-state alkaline polymer Zn-air battery, which consists of a zinc-gel anode, an air cathode electrode, and alkaline polymer electrolyte. The formulation of said zinc gel anode is similar to that of alkaline Zn—MnO2 battery. The zinc gel anode contains a mixture of electrolytic dendritic zinc powders, KOH electrolyte, gelling agent and small amount of additives. The air cathode electrode is made by carbon gas diffusion electrode, which comprises two layers, namely gas diffusion layer and active layer. The active layer on the electrolyte side uses a high surface area carbon for oxygen reduction reaction and potassium permanganate and MnO2 as catalysts for oxygen reduction. The diffusion layer on the air side has high PTFE content to prevent KOH electrolyte from weeping or climbing. Due to adequate amount of fresh air and oxygen supply, the air cathode electrode can run continuously.

Abstract: A method for preparing a composite alkaline solid polymer electrolyte from polyvinyl alcohol (PVA) polymer, potassium hydroxide and water. The polymer electrolyte is reinforced with glass-fiber cloth to increase a mechanical strength, thermal stability and electrochemical stability. A glass fiber cloth matrix provides a stable interface between a cathode and an anode to reduce a short circuit problem when the battery discharges at high rate. The processes for polymer electrolyte are controlled by molecular weight of PVA polymer, the sequence of feeding in reactants, the weight proportions of reactants, the reaction time, the reaction temperature, and the drying conditions, i.e., under the specified conditions of relative humidity (RH), temperature and drying time. The resulting electrolyte exhibits ionic conductivity of 0.15 S/cm or better at room temperature and has high mechanical intensity and good electrochemical stability.
