  • Patent number: 11208351
    Abstract: Electromagnetically-induced cement concrete crack self-healing diisocyanate microcapsules include raw materials, in parts by weight, comprising 15-55 parts of petroleum resin, 5-10 parts of paraffin, 5-10 parts of polyethylene wax, 3-10 parts of magnetic iron powder and 20-67 parts of diisocyanate. The diisocyanate microcapsules use the diisocyanate as a core material, and the petroleum resin/paraffin/polyethylene wax/magnetic iron powder mixture as the shell of the capsule. When micro cracks occur in the concrete, the crack propagation can break partial of the microcapsule inside, the diisocyanate inside the microcapsules flows out and diffuses into the crack and is subjected to a solidifying reaction with water in the concrete, so that the crack is repaired in time; and for the microcapsules that are not broken by cracks, external electromagnetic field can be applied to melt the shell to release the diisocyanate inside, thereby diffusing into cracks and solidify with water to repair them.

  • Patent number: 10931266
    Abstract: A flip-flop element is configured to gate the clock inversions within a master-slave flip-flop element. The flip-flop element reduces the number of circuit elements within the flip-flop element by collapsing elements with common functionality into a single circuit element. Further, by making the actions of judiciously selected circuit elements conditional upon the state of the input data, the flip-flop element circuit reduces the number of internal transitions. In this manner, by reducing the number of circuit elements as well as the number of transitions, the flip-flop element achieves substantial reduction in overall system power consumption, resulting in a more efficient system.

  • Patent number: 10181842
    Abstract: A flip-flop element is configured to include FinFET technology transistors with a mix of threshold voltage levels. The data input path includes FinFET transistors configured with high voltage thresholds (HVT). The clock input path includes transistors configured with standard voltage thresholds (SVT). By including FinFET transistors with SVT thresholds in the clock signal path, the Miller capacitance of the clock signal path is reduced relative to HVT FinFET transistors, leading to lower rise time and correspondingly lower hold time. By including HVT threshold devices in the data input path, the flip-flop element attains high speed and low power operation. By including SVT threshold devices in the clock signal path, the flip-flop element achieves faster switching times in the clock signal path.

  • Patent number: 9315420
    Abstract: The present invention relates to a preparation method for a UV-shielding material based on Mg—Al Layered Double Hydroxide. The material with multi-layered overlay structure is made from Mg—Al double hydroxide layers and interlayer carbonate, its molecular composition is: Mg1-xAlx(OH)2(CO3)x/2.mH2O. The inorganic layers of this material can play a physical shielding role against UV, and the metal elements dispersed on the layer as well as the interlayer anion can play a great role in the chemical absorbing. In addition, by controlling the particle size and the amount of the layers, UV light can be effectively shielded by multi-level reflection and absorption of the multi-level layered structure. Therefore, the material with multi-level chemical and physical shielding properties has a good UV barrier effect for the anti-ageing asphalt, and could significantly increase its UV resistance properties.
