摘要:
Leakage current due to light incident upon the semiconductor layer which forms the channel of a TFT is eliminated. An insulating layer is formed between one of source and drain electrodes and the semiconductor layer over a distance which is longer than a hole-electron recombination distance, from all the edges of at least one of the source and drain electrodes of the TFT so that it overlaps the semiconductor layer.

A redundantly constructed liquid crystal display which has high aperture efficiency. Pixels are arranged in a matrix at the intersections of scan and data lines and storage capacitor lines are provided to supply the pixels with storage capacitors. The pixels are arranged in groups of two pixels adjoining each other by arranging scan lines (or data lines) in groups of two pixels closely adjoining each other. One storage capacitor line is provided for every two adjoining pixels between the scan lines (or data lines) and disposed in the same direction as the scan lines (or data lines). Two storage capacitors corresponding to the two adjoining pixels are provided for each storage capacitor line and one auxiliary storage capacitor is provided to be shared by every two adjoining pixels. Alternatively, both the scan lines and the data lines may be arranged in groups of two closely adjacent lines so that a unit or group of four adjacent pixels is formed. The storage capacitor line, then has associated with it a storage capacitor for each of the four pixels and a single auxiliary storage capacitor for the four pixels.

This invention relates to solid polymer electrolyte materials for use in one or more electrode of a fuel cell. The solid polymer electrolyte materials comprise one or more ionomer which comprises polymerized units of monomers A and monomers B, wherein monomers A are perfluoro dioxole or perfluoro dioxolane monomers, and the monomers B are functionalized perfluoro olefins having fluoroalkyl sulfonyl, fluoroalkyl sulfonate or fluoroalkyl sulfonic acid pendant groups, CF2═CF(O)[CF2]nSO2X. The ionomer of the solid polymer electrolyte material has a number average molecular weight, Mn, of greater than 140,000. Specifically, the ionomers of the invention may find use in the catalyst layer of an electrode because the high molecular weight ionomers mitigate the formation of cracks in the catalyst layer.

摘要:
A light wavelength converter comprising a substrate that is made of a material with a non-linear optical effect, and a loop-shaped optical waveguide that is formed on the substrate, whereby a second harmonic wave or a sum wave emanates from a fundamental wave that has been propagated in a specific area of the optical waveguide and part of the fundamental wave that has not been converted to the second harmonic wave or the sum wave is returned to the specific area of the optical waveguide, so that a fundamental wave with a relatively low output can be efficiently converted to a second harmonic wave and a high-output second harmonic wave can be obtained.
摘要:
A semiconductor laser element of the present invention provides a double hetero junction structure having two clad layers and an active layer formed between the two clad layers. High resistance regions are formed vertically to the light propagating direction at almost the same interval as the light wavelength in at least one of the two clad layers. The high resistance regions form a periodic current blocking structure so the semiconductor laser element may oscillate in a single longitudinal mode even in a non-steady state operation.

A vapor phase synthesis of carbon film and carbon particles using a single or a mixed gas capable of supplying halogen, hydrogen and carbon atoms is disclosed. Halogen radicals can suppress the desorption of carbon atoms from the substrate, and the carbon layer is obtained easily. Especially chlorine and fluorine atoms are effective. An electron beam diffraction pattern illustrated that diamond film can be obtained in this method.
