An improved structure of a planar heat pipe, having a top lid and a bottom lid. The bottom lid can be engaged with the top lid. A wick structure and a working fluid are installed in the heat pipe. The top lid has a top panel, which has a central flat area and a plurality of independent heat dissipating fins spirally arranged around the flat area. Each of the heat dissipating fins has a cone shape, and the height of the heat dissipating fins gradually increases from the center to the periphery of the top lid. A spiral heat circulating path is thus formed on the top lid. Thereby, when the cooling fan generates cooling air flow downwardly, an air impingement is formed upon the flat region of the top lid. The heat accumulated in the central flat region is then dissipated by the heat dissipating fins with an enhanced efficiency.

The partition wall has a multiplicity of defined zones for the flexible positioning of holding fixtures for the connection of accessories such as flat screens, baby carriers, newspaper racks, and similar, and which is dimensioned for a maximum population with accessories.

The invention discloses a conductive agent dispersion liquid and a preparation method thereof. The conductive agent dispersion liquid contains a conductive agent, a solvent and a dispersion agent, wherein the dispersion agent contains aromatic rings and can be bound with the surface of the conductive agent by Van der Waals force among molecules and pi-pi action force between planes; and the solubility in the first solvent at the temperature of 25 DEG C is not smaller than 10wt%. The invention also discloses an electrode slurry and a preparation method thereof, and a battery electrode preparedfrom the electrode slurry and a battery. As using the matter which contains the aromatic rings and can be bound with the surface of the conductive agent by Van der Waals force among molecules and pi-pi action force between planes as the dispersion agent of the conductive agent, the battery capacitance, the charging and discharging capacitance and the rate discharge property are effectively enhanced.

A planar antenna device is mounted on a board including a dielectric layer and two conductor layers vertically sandwiching the dielectric layer. The upper conductor layer includes a first radiating element having an end portion connected through a via hole to a ground formed by the lower conductor layer, a second radiating element having an open end portion, first and second ground conductors connected to respective base portions of the first and second radiating elements via resistors, and a feeder line configured to feed power to the first and second radiating elements.

The invention relates to an organic electroluminescent material and a preparation method thereof, which solves the technical problem that the luminous efficiency of the existing luminescent material still cannot meet the requirements of OLEDs. Organic electroluminescent materials are based on indenofluorene compounds, a new class of organic light-emitting materials synthesized by linking indenofluorene compounds molecules together through diamine compounds containing different substituents. The steric hindrance of the introduced substituent prevents molecules from approaching in space to improve the film-forming performance, and the introduction of the substituent also improves the solubility of this type of material. The luminous efficiency of the material in the dilute solution is 97%, and the luminous efficiency in the thin film is 81%, indicating that the indenofluorene compound has high luminous efficiency. Compared with 2-bromo-5,5,10,10,15,15-hexaethyl-10,15-dihydro-5H-indenofluorene, the indenofluorene organic electroluminescent material provided by the present invention has The preparation method has relatively simple synthesis and purification, low cost, and can meet the needs of industrialization development. The yield of the product is greatly improved, and the purity is high, and the HPLC purity is greater than 98%. Moreover, the prepared material can significantly improve the efficiency, and have obvious improvements in film-forming performance and service life.
