A method for the manufacture of a fiber reinforced plastic structure, comprising the steps of winding a continuous long-staple fiber impregnated with a liquid resin around a plurality of winding jigs until the resultant bundle of resin impregnated fibers attains a predetermined thickness; setting rings tightly in place on the linear portions of the resin impregnated fiber bundle between the jigs; and moving the tightly set rings relative to the linear portions thereby wringing the resin impregnated fiber bundle and expelling bubbles entrapped within the fiber bundle.

An electromagnetic induction apparatus having an even number of coaxially disposed flat coils each having a main winding conductor and tap winding conductors wound in parallel along at least a portion of the main winding conductor to form together a flat coil. The main winding conductors are connected together by connecting the inner end of the main winding conductor of each odd-numbered one of the even number of flat coils to the inner end of the main winding conductor of the adjacent even-numbered flat coil, and connecting the outer end of the main winding conductor of the even-numbered flat coil to the outer end of the main winding conductor of the succeeding odd-numbered flat coil. The tap winding conductors are connected together by connecting the inner end of each of the tap winding conductors of each odd-numbered one of the even number of flat coils to the inner end of the corresponding tap winding conductor of the adjacent even-numbered flat coil, and connecting the outer end of each of the tap winding conductors of the even-numbered flat coil to the outer end of the corresponding tap winding conductor of the succeeding even-numbered flat coil. Upright lead portions are formed on each of the outer ends of both the main winding conductors and the tap winding conductors of flat coils which are located at opposite ends of the even number of flat coils.

摘要:
An image retention phenomenon and black unevenness generated after long-time operation in the liquid crystal device are prevented. By using a material having a polyamide acid ester as a precursor less likely to adsorb impurities on a boundary for an alignment film and a material having a dielectric constant anisotropy Δ∈ of 5 or less for liquid crystals, adsorption of an antioxidant dispersed in the liquid crystals is suppressed to prevent oxidation of the liquid crystals. The extent that impurities are intruded into the liquid crystals is reduced by restricting the dielectric constant anisotropy Δ∈ of the liquid crystals to 5 or less, thereby capable of preventing the image retention phenomenon and the black unevenness.

A liquid crystal display apparatus includes a white color light source and a coloring light source, a detection circuit which detects a brightness of an input image signal, an image quality processing calculation circuit, a light source control circuit, and an image control circuit. The coloring light source includes a blue light source. The image quality processing calculation circuit outputs to the light source control circuit a light source control signal for (1) increasing a light intensity of the coloring light source when an average luminance of the input image signal is detected to be higher than a predetermined luminance based on a detection result of the detection circuit, and for (2) turning-on only the white color light source without turning-on the coloring light source when the average luminance of the input image signal is detected to be lower than the predetermined luminance.
