Abstract: A mobile phone is electronics with 2D and 3D display function, having a first casing and a second casing linked to allow the phone to be foldable, and including a first display unit located inside with the phone folded, and selectively switching and displaying 2D and 3D images, and a second display unit located outside with the phone folded, and displaying a 2D image. When the mobile phone is opened or open the first display unit displays an idle screen in a 3D image as desired.

Abstract: In an electronic equipment provided with 2D (two-dimensional) and 3D (three-dimensional) displaying functions, an easily viewable 2D image screen and an enjoyable 3D image screen are switched and displayed with a simple key operation. A first display portion of the electronic equipment does not generate optical parallax during the display of 2D image, enabling display of an easily viewable 2D image screen. The electronic equipment shares the data, permitting switching of the 2D image display to 3D image display.

Abstract: It is an object of the invention to provide a method, and an apparatus, capable of fabricating a nano-sized carbon material excellent in quality by use of a three-dimensional discharge apparatus on a mass production basis. There are installed 12 pieces of discharge electrodes, 6 pieces each being horizontally disposed in two tiers, upper tier and lower tier, at a side face part of the discharge vessel. The 6 pieces of the discharge electrodes, in the upper tier and lower tier, respectively, are disposed so as to be angularly shifted by 60 degrees from each other along the horizontal plane, and it is set such that the respective discharge electrodes in the upper tier are disposed so as to be angularly shifted by 30 degrees from the respective discharge electrodes in lower tier as seen from above.

Abstract: A measuring device for amount of charge of developer includes an upper electrode, a lower electrode provided under the upper electrode, which are provided in parallel so as to face each other, flying electric field voltage application unit for applying a flying electric field voltage to the upper electrode, for generating an electric field so as to fly developer from the lower electrode to the upper electrode, current detection unit for detecting a current flowing in the upper electrode, and arithmetic unit for computing a total amount of charge of the developer adhering to the upper electrode based on a change in amount of current detected by the current detection unit, wherein a current that generates as a toner T adheres to the upper electrode is detected by the current detection unit, and based on a change in amount of the current, a total amount of charge of the developer adhering to the upper electrode is computed by the arithmetic unit.

Abstract: An image processing apparatus includes a detecting section for detecting a density value as a threshold value for suppressing an effect from a background from image data composed of plural picture element data obtained by digitizing each picture element of the image and a density converting section for outputting the image data after converting density values of the picture element data whose density values are below the threshold value into a predetermined value indicating white when the density value of the picture element data is below the threshold value. The detecting section computes a degree of separation indicating a ratio of a between-class dispersion to a within-class dispersion of two classes divided by the threshold value by sequentially varying the density value. Then, the density value corresponding to a gravitational center of a differential histogram showing the respective differences in degree of separation from a density Tm which maximizes the degree of separation to a highest density Te.
