Abstract: In a method for manufacturing a laminated coil component, in which a laminated coil component is manufactured by laminating insulator sheets in order on which conductors having predetermined patterns are formed, the insulator sheets are laminated such that a distance in a lamination direction between a first lead-out conductor laminated first and a first coil conductor laminated next is larger than a distance in the lamination direction between a second lead-out conductor laminated last and a second coil conductor laminated immediately before the second lead-out conductor.

Abstract: A polarization conversion device includes: a first polarization conversion unit that, on the basis of time-division display type stereoscopic image data including left images for left eye and right images for right eye, polarization-converts light beams of the left images and the right images output from a display unit that displays the left images and the right images and outputs polarized lights; a second polarization conversion unit that polarization-converts the polarized lights entering from the first polarization conversion unit and outputs polarized lights; and a control unit that controls times when the first and second polarization conversion units perform polarization conversion so that phase differences between the polarized lights of the left images and the right images may be inverted to each other at times when the left images and the right images are switched and displayed on the display unit.

Abstract: A liquid crystal display device using an LCD panel made for display of computer output, wherein video signals of a predetermined television system are converted by a decoder into field-unit picture data, and frame-unit picture data obtained therefrom by a converter are supplied to an LCD panel to display a picture composed of such video signals. The picture is displayed on an effective screen of the display panel at the original aspect ratio of the video signals of a television system by changing the width-to-height ratio of each unit pixel formed on the effective screen of the display panel, on the basis of the ratio of the number of horizontal pixels to the number of vertical pixels of the frame-unit picture data, and also on the basis of the aspect ratio of the predetermined television system.

Abstract: The invention provides a display state detection method which allows the display state of an information display apparatus to be supervised accurately without giving any obstacle to a user, a display state adjustment method and a maintenance management method by which the display state can be kept good as well as an information display apparatus. Optical sensors are disposed on the rear face side of a plasma display panel and catch rear face side outgoing light, which increases in proportion to the outgoing light amount to the display face side of the plasma display panel, to detect a panel display state, and the display state of the plasma display panel is automatically adjusted based on a result of the detection. When adjustment is impossible, the apparatus itself outputs an alarm and accumulates an adjustment history and/or a failure history.

Abstract: A monitor television receiver for displaying or supplying a color video output has a circuit for measuring the cathode currents of electron guns for three primary colors in a cathode-ray tube. A memory stores coefficients to form functional expressions relative to the cathode currents and the luminance and also stores chromaticity points of three-color fluorescers. An input receives color temperature data and luminance data from external sources, and an arithmetic unit calculates the luminances of the three-color fluorescers corresponding to the input luminance data and color temperature data and also calculates the cathode currents of the electron guns corresponding to the color temperature data and the luminance data from the input. A CRT drive circuit is controlled in such a manner that the measured cathode currents are rendered coincident with the cathode currents calculated by the arithmetic unit.

Abstract: An apparatus for automatically establishing a color balance for a color television monitor includes a sensor device which is separably attached to the screen of the monitor to detect the brightness of the ambient light. The ambient light brightness detected when no image is displayed is used to compensate reference data for establishing a color balance of the color signals independent of the ambient light.
