8502 results about "Plastic film" patented technology

Plastic film is a thin continuous polymeric material. Thicker plastic material is often called a "sheet". These thin plastic membranes are used to separate areas or volumes, to hold items, to act as barriers, or as printable surfaces.

Active matrix liquid crystal display panel

An active matrix liquid crystal display panel by which a good display characteristic can be obtained without suffering from gradation reversal over a wide visibility angle range. A liquid crystal layer 4 is formed such that the thickness thereof varies in accordance with transmission wavelengths of color layers 6, 7 and 8 so that a very good display which does not exhibit any coloring in whichever direction it is viewed may be obtained.
An active matrix substrate A includes a plurality of opposing electrodes 2, a plurality of pixel electrodes 3 parallel to the opposing electrodes 2, a thin film transistor, and an orientation film 23 all formed on a glass substrate 10. A color filter substrate C includes an orientation film 56 provided on one surface of another glass substrate 10 and an optical compensation layer 35 provided on the other surface of the glass substrate 10 and formed from a plastic film. The two substrates are disposed such that the orientation films thereof oppose each other, and polarization plates 34 and 5 are disposed on the outer sides of the two substrates, and a liquid crystal layer 4 having a positive refractive index anisotropy is provided between the orientation films 23. The optical compensation layer 35 has a negative one axial refractive index anisotropy and can cancel a retardation produced in the liquid crystal layer 4 thereby to suppress white floating of a black display portion.

Oleochemical Plasticizers with Thermal and Ultraviolet Radiation Stabilizing Activity for PVC Molding Resins and Process for Obtaining Thereof

The present invention is related with bioplasticizers or primary oleochemical plasticizers and the improved process for obtaining thereof. It refers primarily to epoxydized oleochemical plasticizers produced from vegetable oils, as substitute of traditional petrochemical plasticizers. The process starts with the epoxydized product of natural oils, such as sunflower, linseed, Jatropha curcas, soybean, etc., which are transesterified with an alcohol such as ethylic or methylic, in the presence of a catalyst such as sodium methoxide or sodium hydroxide in order to produce an alkylic esters mixture of the fatty acids that were present in the oil or oil mixture used as raw material in the epoxydized oil production. When the plasticizer obtained by the process already mentioned is used for the formulation of moldable poly(vinyl chloride), PVC, resins; the resulting plastic films get adequate hardness, static and dynamic thermal stability, and plasticizer extractability by solvents, such as n-hexane, gasoline and oil. Besides, when the PVC resin is formulated with a phthalic or terephthalic plasticizers mixture and the bioplasticizer, the bioplasticizer presents a full range solubility and or compatibility with the remainder of the resin compounds. The oxyrane chemical ring of the bioplasticizer is an excellent chemical neutralizer of the HCL that might be formed from the PVC, due to the action or interference of thermal or UV radiation.

System of Wireless Electronic Registration Plates

The system of wireless electronic registration plates (3) which is comprehended by the existance of the central wireless module (29) placed within the motor vehicle and connected on to an electric energy source, and the wireless electronic registration plates (30, 31), that are placed at the front and the rear sides of a motor vehicle, containing built-in satellite wireless module (11) is functioning on a principle of wireless micro network where the data transfer from a computer or other mobile device for data input (27, 28) is made through the central wireless module to the satellite wireless modules embedded into the registration plates. The wireless electronic registration plates have its own source of electric energy from the solar cells (6) placed in the lower part of the solar housing (22), which are connected to a thin, film battery (8) implanted in to the solar housing of the registration plates. The registration data is displayed through the active display (1) that is embedded in the solar housing. The active display is made of two flexible parts, the front plane laminate i.e. electronic paper (13) which consist of the layer of electronic ink (17) and the plastic film on the surface (15) containing transparent conducting electrodes (16), and the back plane laminate (14) containing the electronic complex (9) and the control module (10) enabling regulation and control of the displayed information. In the electronic complex there is a wireless (Bluetooth) module (11) for wireless communication and data transfer. The wireless electronic registration plates are laminated with highly resistant and protective plastic (26) and on the back side of the registration plates there is an acrylic, double sided, epoxy gluing tape (25) that enables for direct affixing of the registration plates on to a vehicle body, bumpers or the registration plate holders.
