Abstract:
An electrode roll for resistance welding comprising a fixed portion which has a disc portion at the longitudinal center part of a shaft where the disc portion and the shaft are at right angles to each other; a rotary portion which surrounds the fixed portion and has inner surfaces forming two side gaps facing the two side surfaces of the disc portion and a peripheral gap facing the peripheral surface of the disc portion, respectively; and a conductive liquid metal received in each of the gaps, where the peripheral gap is so narrow that the above conductive liquid metal may be pulled up along the gap to fill the same when the above rotary portion rotates, and the side gaps are substantially wider than the peripheral gap.
Abstract:
A solder for filling or padding operations on automobile bodies, consisting essentially of 2.0-7.0 Wt% antimony, optionally less than 5.0 Wt% of tin and the balance of lead. This solder is inexpensive and exhibits good physical properties at high temperatures principally due to its high solidus temperature of above 240.degree. C. The use of this solder is particularly advantageous when the filling or padding operations are preparatory to a surface coating operation in which a high baking temperature is employed for hardening enamel paint or varnish.
Abstract:
An image forming apparatus that prints and edits a document includes a user identification portion, a print management portion that records print management information indicating a user who performs abort operation of printing, an edit management portion that records edit management information, a determination portion that determines, based on the print management information, whether or not the user is a print suspended operator who has performed the abort operation previously, a page extraction portion that, when the print suspended operator performs reprinting operation for giving instructions to print the document that has been updated, extracts pages of the document which were printed successfully when printing of the document was suspended and have been updated thereafter, and a print controller that controls the image forming apparatus such that the image forming apparatus prints at least unprinted pages of the document and the pages extracted by the page extraction portion.
Abstract:
A plurality of image processing servers in charge of a first-order service individually transmit their server selection information to a plurality of image processing servers in charge of a second-order service, and those in charge of the second-order service individually select one of those in charge of the first-order service as the most preferred server based on the server selection information received therefrom. Similarly, a plurality of image processing servers in charge of a third-order service individually select one of those in charge of the second-order service as the most preferred server based on the server selection information of those in charge of the second-order service received therefrom. Also similarly, an image forming apparatus selects one of a plurality of image processing servers in charge of the final service as the most preferred server based on the server selection information of those in charge of the final service received therefrom.
Abstract:
An image processing system includes an image forming apparatus and first and second image processing servers connected to the image forming apparatus via a network, the first image processing server includes: a first image processor which performs a first image processing operation on target image data received from the image forming apparatus; and a protected area calculator which calculates a protected area to be prohibited from being processed next, which is related to the area processed by the first image processor, and generates image protection information including information of the protected area, and the second image processing server includes a second image processor which performs a second image processing operation on the areas excluding the protected area whose information is included in the image protection information generated by the protected area calculator.
Abstract:
An image processing device includes an operation panel on which a plurality of operation keys is arranged, and a storage part that stores key information allocated to a predetermined operation key of a plurality of operation keys, and with which an user authentication information for authenticating a user authorized to use a function corresponding to the predetermined operation key and an authentication activation information in which conditions for user authentication to be executed when the predetermined operation key is operated are defined are associated. An authentication part reads the user authentication information and the authentication activation information based on the key information when the predetermined operation key is operated, and executes user authentication based on the user authentication information if conditions defined in the authentication activation information are met. A key operation enabling part enables a key operation of the predetermined operation key when user authentication results in success.

Abstract:
A heat-producing element for fixing a toner image on an image support, in which the heat-producing element comprises a heat-resistant resin and electrically-conductive fiber having a shape stipulated by conditions 1, 2 and 3. 1. Aspect ratio: 0.025≦(A/B)≦0.25 2. Diameter of electrically-conductive fiber (A): 0.5 μm≦A≦3 0 μm 3. Length of electrically-conductive fiber (B): 5.0 μm≦B≦1,000 μm
Abstract:
This is to provide an image processing apparatus and others capable of ensuring security by shortening the connecting time of an external recording medium when a plurality of jobs including target data pieces encrypted with shared keys and the shared keys encrypted with a user's public key are executed. A job including a target data piece encrypted with a shared key and the shared key encrypted with a user's public key are received and stored in a job storage. To execute the plurality of jobs stored therein, the encrypted shared keys included in the respective jobs are decrypted with a secret key by the external recording medium. After completely obtaining all the plurality of decrypted shared keys, the target data pieces are decrypted with their matching decrypted shared keys, and then the jobs are executed.
