  • Patent number: 10759757
    Abstract: A method of preparing a crystalline contrast agent for magnetic resonance imaging from a zwitterionic carboxylic pyridyl ligand includes mixing metal ion and the pyridyl ligand and obtaining crystals therefrom. The crystalline contrast agent includes a manganese-organic or gadolinium-organic 3D framework. The crystalline contrast agent is employed in a kit and a pharmaceutically acceptable composition. The method allows for preparing crystalline contrast agents with superior properties with easily available starting materials and with an economic and efficient process. The method allows for preparing crystalline contrast agents with exceptional water-stability and water-solubility, which exhibit high longitudinal relaxivities and with excellent stabilities under physiological conditions and low cytotoxicity. Further provided is a method for in vivo imaging of a subject, in particular a human, comprising administering the crystalline contrast agent to the subject.

  • Patent number: 8889051
    Abstract: A mold and a method for integrally manufacturing a functional cored slab and a solid slab with a polygonal grid honeycomb structure. The mold for manufacturing the cored slab comprises a female mold and multiple male molds which are provided in the female mold. The male molds include polygonal cylinders capable of melting, dissolving, or vaporizing. A clearance exists between at least one pair of adjacent polygonal cylinders. The mold for manufacturing the solid slab is provided with a male mold main-body of polygonal cylinders which share the same shape and amount as the polygonal grids. The male mold main-body, which is made of one of the functional materials including sound insulating materials, flame retardant materials, and thermal insulating materials, is located in the frame-like female mold having a bottom plate. Clearances are provided between the adjacent male mold bodies. A casting method is adopted when manufacturing the slabs.

  • Patent number: 8775693
    Abstract: An SD/SDIO host controller is disclosed, which includes a control register and interrupt generation module, an internal DMA module, an SD/SDIO command interface module, an SD/SDIO data interface module, and a frequency divider and trigger/sampling enable signal generation module which is connected to an output end of the control register and interrupt generation module; the frequency divider and trigger/sampling enable signal generation module employs a frequency divider to perform frequency division on a local high-speed clock so as to obtain the operating clock of the SD/SDIO card, and simultaneously generates a trigger/sampling enable signal by the frequency divider and enables the position of the enable signal to be adjustable with respect to the operating clock of the SD/SDIO card. The present invention is capable of solving the setup/hold time issues caused by delay in digital signals.

  • Publication number: 20130021422
    Abstract: An inkless printing method with heating process is disclosed. In the method, a conventional printing paper (15) is used, and a printing head (4,27) contacts the printing paper directly or indirectly. A heating element (13,22) is placed in the printing head(4,27), which provides heat energy to cause a color change in a surface layer of the paper, thereby producing a character or an image. When the printing head (4,27) contacts the printing paper directly, a temperature of the printing head (4,27) is set to 100-1000° C.; and a stagnation time of the printing head (4,27) is set to 0.1-100 ms; when the printing head (4,27) contacts the printing paper indirectly, a temperature of the printing head (4,27) is set to 200-1000° C. The method does not need to use toner, ink or paint, and only needs conventional printing paper (15) and said heating process to achieve printing effect. A printing head unit to be used in said printing method is also disclosed.
