Abstract: A document detecting unit detects a document from color image data of a plurality of rectangular areas at a specific position on a scanning plate, to determine a document size in a main-scanning direction. An average-value calculating unit calculates an average value of each component of the color image data in a rectangular area. A binarizing unit binarizes the average value calculated by the average-value calculating unit. A determining unit determines a presence of the document based on a result obtained by the binarizing unit.

Abstract: An acceleration sensor comprises a fixed case member and a cover assembly collectively defining a closed space in which the oscillation plate and the piezoelectric element received therein. The oscillation plate and the piezoelectric element are oscillatably supported by a supporting portion formed on the central bottom portion of the fixed case member. The oscillation plate and the piezoelectric element are integrally oscillatable in two different modes consisting of: a 1/1 oscillation mode where the oscillation plate is irregularly deformed to have the peripheral portion oscillated with a single vector in the oscillation direction of the oscillation plate when the oscillation plate is oscillated with respect to the fixed case member at a resonance frequency f0; and a 1/2 oscillation mode where the oscillation plate is irregularly deformed to have two different half parts of the peripheral portion oscillated with their respective different vectors opposite to each other in the oscillation direction of the oscillation plate when the oscillation plate is oscillated with respect to the fixed case member at a noise frequency f01, and the resonance frequency f0 and the noise frequency f01 are out of the range of effective oscillation frequencies. Thus constructed acceleration sensor is of high performance and appropriate for automatic production at a low cost.

Abstract: Disclosed herein are a method and apparatus for purifying silicon, which are suitable for economical and mass production of high-purity silicon for solar cells from regular-grade silicon containing boron and carbon in large quantities. The method comprises directing a plasma jet stream of an inert gas toward the surface of molten silicon held in a container lined with silica or a silica-based refractory. For improved purification, the inert gas as the plasma gas is mixed with 0.1-10 vol % steam and/or less than 1 g of silica powder per liter of the inert gas at normal state. Alternatively, the container may have a bottom opening and is provided with an electrode having a cooling means underneath the bottom of the container, with the electrode and the cathode of the plasma torch connected to a power source for plasma generation, so that the plasma jet and electron beam are directed toward the surface of molten silicon.

Abstract: A video display for a liquid crystal display and a method for displaying a complex video signal thereon is provided. A line memory stores one line of video data of a complex video signal. A field memory stores one field of video data of the complex video signal. A signal driving circuit generates a signal driving signal in response to the video data stored in the line memory and the field memory. A multiplexer selectively transmits the video date from the line memory and field memory to the signal driving circuit. One horizontal period of the video signal is sequentially written in the line memory. During the first half of the horizontal period of the video signal, video data of the previous field which is stored in the field memory is transferred to the signal driving circuit. During the second half of the horizontal period, the video data stored in the line memory is transferred to the signal driving circuit. The signal driving circuit generates scanning driving signals for the liquid crystal display, each signal being divided into an odd and even field.
