An image processor includes an image reading unit that reads source documents and converts read data into image data, an extracting unit that extracts password information and attribute information from the image data of each of the source documents read by the image reading unit, a password inputting unit that inputs the password information, a password determining unit that determines whether or not the password information inputted by the password inputting unit matches the password information extracted by the extracting unit, and a permitting unit that permits a source document to be subjected to image processing, if the attribute information of the source document is identical to the attribute information included in the source document of which the password determining unit has determined that there is a match between the inputted password information and the extracted password information.

A method and apparatus is provided for transmitting an orthogonal frequency domain multiple access (OFDMA) signal including a synchronization channel signal transmitted within a localized portion of a bandwidth of the OFDMA signal, the synchronization channel signal having predetermined time domain symmetry within the localized portion of the bandwidth and including information for providing at least partial cell identification information. The synchronization channel signal enables an initial acquisition and cell search method with low computational load which provides OFDMA symbol timing detection and frequency error detection and frame boundary detection and cell specific information detection in an OFDMA system supporting multiple system bandwidths, both synchronized and un-synchronized systems, a large cell index and an OFDMA symbol structure with both short and long cyclic prefix length.

[Problems] To provide an apparatus for feeding resin capable of extinguishing angular traces formed at both end portions of the cutter mark or of preventing the angular traces from extending up to the side wall of the body portion of the preform at the time of forming a preform.[Means for Solution] An apparatus for feeding molten resin to a compression-molding machine, including a holding unit 17 that rotates on a track, the holding unit 17 having a pair of holders 22 and 23 capable of holding and releasing the molten resin. When the molten resin is cut by a cutter, a linear cutter mark 29 is formed on the cut surface of the resin in a direction at right angles with the direction in which the molten resin is cut. Protruded portions 32 and 33 are formed on the inner circumferential surfaces of the holders 22 and 23 to deform the end portions of the cutter mark 29 toward the inside of the cutter mark when the molten resin is held by the pair of holders 22 and 23.

A method for continuously casting a billet with a small cross section in which a curved type or vertical type continuous casting machine is used while oscillating the mold upward and downward is characterized in that the casting machine is provided with a mechanism for withdrawing speed oscillation. The mechanism has structural play in the directions of driving and reverse driving in such a manner that the amount of a play-incurred displacement from the neutral position of the structural play in the direction of billet driving or reverse driving is ±2 to ±30 mm in the direction of driving on the pinch roll circumferential length equivalent basis. The mechanism produces a returning force toward the neutral position and operational parameters such as the billet length, the specific amount of secondary cooling water, the casting speed as well as the oscillation amplitude and frequency are optimized.

In a mold for casting a billet with a curved type continuous casting apparatus, D0 (m) is an inner diameter at a lower mold edge and R0 (m) is a curvature radius of an outer curvature side at the lower mold edge. When a rate of change Tp (%/m) in mold inner diameter per unit length along a casting direction is Tp=(1/D0)×(dD/dx)×100 (%/m), and when a rate of change Rp (%/m) in curvature radius of an outer curvature side per unit length along the casting direction is Rp=(1/R0)×(dR/dx)×100 (%/m), the rate of change Tp in mold inner diameter and the rate of change Rp in curvature radius satisfy a relationship expressed Rp=(Tp/2)×(D0/R0), where D is a mold inner diameter at a distance x away from an upper mold edge and R in Formula 2 is a curvature radius of the outer curvature side at the distance x.

A reflective screen is provided. A reflective screen that displays an image by reflecting light from a light source includes a reflective sheet, a light-scattering sheet, and an adhesive layer bonding the reflective sheet to the light-scattering sheet. The adhesive layer contains a coloring material that absorbs light in a particular wavelength region.

A radio communication system with adaptive interleaving selects between chip interleaving and bit interleaving depending upon the number of active code signals. A transmitted RF signal includes a coded information signal part and a control signal part that indicates a number of active code signals that have been combined to form the coded information signal part. The system is especially suited for MC-CDMA systems.
