  • Patent number: 11435287
    Abstract: Application of a new light-molecule interaction in which molecules enable emission of photons with more energy than that of the absorbed photons achieves higher resolution than fluorescence imaging. This emission phenomenon is termed supracence and is applied to obtain more information about the structure and properties of a specimen than currently possible with fluorescence imaging techniques. Because supracence originates from chemical bonds, any structure that contains chemical bonds meets the necessary condition to potentially emit supracence. Super spectral resolution images are achieved by selectively exciting a target molecule to suprace without exciting another fluorophore that has absorption and emission rather close to the target.

  • Patent number: 11421437
    Abstract: A composite crossarm fixed on a pole body of a transmission pole is disclosed. The composite crossarm includes: a core rod, an insulating layer and a load-bearing member. The insulating layer and the load-bearing member cover and are fixed to an outer peripheral surface of the core rod. The load-bearing member is positioned in a middle region of the core rod connected to the pole body, and the insulating layer is positioned in regions of the core rod other than the middle region. A transmission pole using the above composite crossarm is also disclosed. In the above manner, the load-bearing member is arranged at a position where the core rod is connected to the pole body in advance. On one hand, the core rod is able to be connected to the pole body without providing with a hole. On the other hand, the load caused by the fixed connection is applied on the load-bearing member directly, with no damage to the insulating layer.

  • Patent number: 11322923
    Abstract: An overhead power distribution line (10) comprises a tension resistant pole (101), two composite crossbeams (102) and tension resistant fixing members (103). A middle portion of the composite crossbeam (102) is horizontally secured on the tension resistant pole (101), and end portions of the composite crossbeam (102) are connected to the tension resistant fixing members (103). The tension resistant fixing members (103) enable the two composite crossbeams (102) to integrally connect and are for fixing conducting lines. With the above configuration, two composite crossbeams (102) are secured on the same horizontal plane of the tension resistant pole (101), thus satisfying vertical tension of a tension resistant requirement. Further, by using composited crossbeam bodies (102), a dry arc distance is significantly increased, and electrical lightning resistance performance is enhanced, preventing incidents such as line disconnection and flashover caused by lightning strike.

  • Patent number: 11283254
    Abstract: Provided is a cross arm with one end connected to a tower body and a free end for connecting a conducting wire. Free end comprises an end connecting piece and an extension piece. Extension piece is fixed with end connecting piece. Extension piece protrudes horizontally from end connecting piece. Conducting wire is connected to extension piece. An angle between extension piece and a cross arm center line is greater than that between conducting wire and cross arm center line. Cross arm free end includes a jumper wire device horizontally arranged on end connecting piece for hitching jumper wire. Extension piece use increases distance between conducting wire and tower body when turning angle condition is met. Gap requirement between conducting wire and tower body is met, and cross arm length increase is eliminated. Horizontally arranging jumper wire device on end connecting piece reduces distance between wire layers and tower body size.

  • Patent number: 6033773
    Abstract: The design and synthesis of a family of calix[4]arene-based nonlinear optical (NLO) chromophores are discussed. The calixarene chromophores are macrocyclic compounds consisting of four simple D-.pi.-A units bridged by methylene groups. These molecules were synthesized such that four D-.pi.-A units of the calix[4]arene were aligned along the same direction with the calixarene in a cone conformation. These nonlinear optical super-chromophores were subsequently fabricated into covalently bound self-assembled monolayers on the surfaces of fused silica and silicon. Spectroscopic second harmonic generation (SHG) measurements were carried out to determine the absolute value of the dominant element of the second-order nonlinear susceptibility, d.sub.33, and the average molecular alignment, .PSI.. A value of d.sub.33 =60 pm/V at a fundamental wavelength of 890 nm, and .PSI..about.36.degree. was found with respect to the surface normal.
