Abstract: A document management system acquires a document which is associated to a document ID specified by an access request; generates a new document ID which is associated with the acquired document; and outputs the acquired document and the new document ID to a request origin. The document management system registers associative information on the request origin, the new document ID, and the document ID specified by the access request; generates a new document ID which is associated with a document corresponding to a transferred document ID; replaces the transferred document ID with the new document ID, to cause the new document ID to be transferred to a transfer destination; and registers associative information on a transfer source, the new document ID after replacement, the document ID before replacement, and the transfer destination.
Abstract: There is provided an image reader system including an attribute acquisition unit that acquires an attribute of an original that has been detected by an image reader unit that optically reads an image of the original, and an image output unit that outputs the attribute that has been acquired by the image reader unit and image data that are acquired by the reading of the image reader unit with the attribute and the image data being associated with each other.
Abstract: A backpack frame has a front side and a back side and comprises generally parallel base and top sections that extend transversely across and are spaces one from the other along a center line of the frame. Side rails connect the base section to the top section. The side rails are arranged on opposite sides of the frame center line, and a stabilizing rib interconnects the side rails and extends transversely across the center line at an intermediate location between the base and top sections. The side rails converge inwardly from the base section towards the frame center line to the stabilizing rib, and diverge outwardly from the stabilizing rib and away from the center line to the top section.
Abstract: An approximate curve generation method according to the present invention generates an approximate curve as smooth as an original curve from point group data obtained by approximating a curve shape, and includes: an approximate polygon shape range determining step of sectioning point group data for each line segment of an approximate polygon shape which is generated when the point group data approximating the curve shape are obtained, and sorting the point group data close to a section boundary as valid point group data, and the point group data inside the valid point group data as invalid point group data; and an approximate curve generating step of regarding only the valid point group data, and generating an approximate curve passing through or close to the regarded valid point group data as an approximate curve to be finally obtained.
Abstract: An on-chip amplifier includes first element that curtails the velocity of an incoming light to the amplifier. A second element is doped so as to make the frequency of the incoming light equal to the electron frequency in order to allow for electron-photon wave interaction, so that when current flows through the amplifier, electron power is transferred to the incoming light, resulting in amplification of the incoming light.

Abstract: A pocket comprises an inner cup cooperating in a nested relationship with an outer cup to define a chamber having a closed bottom end and an open upper end sized to receive an article. A hinge interconnects the inner and outer cups at the closed bottom end of the chamber. The hinge is configured to accommodate swinging movement of the outer cup relative to the inner cup between a closed position at which the sides of the article received in the chamber are tightly confined between opposite interior surfaces of the inner and outer cups, and a release position deflected outwardly from the closed position to accommodate removal of the article from the chamber via its open upper end.
Abstract: A distributed load monopole antenna system is disclosed that includes a monopole antenna including a radiation resistance unit, a current enhancing unit, and a conductive mid-section.

Abstract: A radiant electric heating element for use in a toast making appliance comprises a base plate (2) of stainless steel to one or each face of which there is printed a first ceramic track (3) with an electrically conductive track (5) printed on the face thereof remote from the base plate (2), and a second ceramic track (4) is printed upon and surrounds the heating track (5) thus hermetically sealing with the heating track between the two ceramic tracks. Such an element provides adequate radiant heat for efficiently toasting bread while the bread may be in direct contact with the element but is electrically insulated therefrom by the second ceramic track (4). By providing a further ceramic coating (6) on the opposed face of the base plate (2), mechanical integrity is maintained to prevent warping of the element and thus uneven toasting.
