  • Patent number: 7729514
    Abstract: A display section displays a speedometer having a substantially circular shape on an outer circumference of which a speed scale is provided. Then, that point on the outer circumference of the speedometer which indicates a speed at a moment is calculated. Further a speed that is attained at a given time period (e.g. 0.5 second) after the moment if the speed is increased at an acceleration at the moment is calculated. An arc-shaped pointer is displayed, the arc-shaped pointer passing (i) the calculated point of the speed scale, (ii) a middle point between the calculated point of the speed scale and a center of the speedometer, and (iii) the center of the speedometer. With this arrangement, a display device displaying the speedometer allows a driver to easily recognize the speed and an amount of a change therein (i.e. acceleration).

  • Publication number: 20080023650
    Abstract: A radiation image conversion panel includes a substrate, a phosphor layer formed on the substrate by vapor-phase deposition, and a protective layer covering entirely the phosphor layer to hermetically seal it. A color at a surface of the panel on which exciting light is incident has a density of 0.001 to 0.095 and the color is a color corresponding to a wavelength of 440 nm. A process for producing the panel forms the phosphor layer on the substrate by the vapor-phase deposition and subjects the phosphor layer to a thermal treatment. The process may subject as the thermal treatment the phosphor layer to one or more cycles of a first thermal treatment for heating and cooling it and to only one cycle of a second thermal treatment for heating it in a presence of oxygen. The process further subjects the phosphor layer to humidification which is a treatment for making it absorb moisture.
