Abstract: An image reading apparatus includes a separating roller that is capable of switching between a separation state in which an original document is separated and a non-separation state in which the original document is not separated, and determines whether or not the original document is fed in the separation state or the non-separation state based on the types of the original document set through a user interface for instructing a select of the types of the original document to be read and a start of reading the original document.

Abstract: A scanner includes a reading unit that reads an image of a paper, a medium feeding portion that is capable of selecting a first feeding mode in which a separation feeding for separately feeding a paper bundle in which a plurality of sheets of paper is overlapped with each other is performed and a second feeding mode in which a non-separation feeding for collectively feeding the paper bundle without separating is performed, and a pair of first transporting rollers and a pair of second transporting rollers that transport the paper fed by the medium feeding portion, in a case in which the medium feeding portion feeds the paper in the second feeding mode, a first driven roller and a second driven roller respectively constituting the pair of first transporting rollers and the pair of second transporting rollers are driven in a rotation direction where the paper is transported.

Abstract: An ultrasonic cleaning apparatus capable of cleaning large-sized objects includes: a casing having a bottom surface that forms a tilted surface to oppose the object to be cleaned and having an ultrasonic transducer provided at an inner lower surface; a cleaning liquid supply device configured to supply cleaning liquid to a casing bottom surface; and a flow-speed accelerator that ejects the cleaning liquid by accelerating the flow speed of the cleaning liquid from the cleaning liquid supply device. The casing is formed by a main body including an upper plate, a projected part attached to a lower part of the upper plate, an outer lateral face extended from the projected part in a downward direction, and the bottom surface connected integrally at a lower end part of the outer lateral face. The bottom surface is formed to be tilted at a prescribed angle with respect to a horizontal plane.

Abstract: A digital signal reproducing apparatus capable of reproducing video and audio information from a compact disk without losing the beginning of the video and audio information even when reproducing disks wherein the video and audio information are recorded simultaneously from the first block of any specified selection, said apparatus includes a reproduction position detector for outputting the current reproduction position based on the subcode information. An offset reproducer offsets the disk track being reproduced to a track position before the current reproduction position after accessing the specified reproduction position, then resuming reproduction. First and second shift controllers outputs first and second shift position information obtained by adding or subtracting a constant value to the access position information when initial access is completed.

Abstract: A liquid crystal display (LCD) circuit comprising a duty changing device for changing the driving duty cycle of an LCD in accordance with a power supply switching command signal, and a bias changing device for changing the display bias voltage produced by a bias producing device to cause the LCD to display information, in accordance with a power supply switching command signal externally supplied to the LCD circuit. Even when electric power to be supplied from plural power supplies to the bias producing device is switched in accordance with the power supply switching command signal, a change in the display contrast of the LCD can be suppressed.

Abstract: The present invention relates to polymerizable cyclic urea derivatives which can be thermally split to give rise to an isocyanate group; and to a polymer having cyclic urea pendant groups, which can be cured by heating without any additional curing agent such as an isocyanate blocked with a volatile lower molecular weight material, so that volatile material is not released in a thermal curing process.

Abstract: A signal recording and reproduction system is used in recording and reproducing signals on and from a recording medium such as a compact disk, laser disk, video disk or digital audio tape. Index data for the recorded contents such as Table of Contents data (TOC) or the like, are stored in the recording medium. The signal recording and reproduction system confirms the time necessary for playing or reproducing a desired reproduction range of record sections in the recording medium, using a small number of steps of operation.
