Abstract: A chromium plating bath containing trivalent chromium ions and hexavalent chromium ions is prepared by a method including the steps of: (A) mixing chromic acid and an organic acid in an aqueous solution containing these acids and reducing chromic acid by the organic acid so as to prepare an aqueous solution not containing hexavalent chromium ions; (B) adding a pH adjustor to the aqueous solution not containing hexavalent chromium ions so as to adjust pH to a value of 1 to 4; and (C) further adding chromic acid to the aqueous solution not containing hexavalent chromium ions and having undergone the pH adjustment so as to prepare an aqueous solution containing trivalent chromium ions and hexavalent chromium ions. The chromium plating bath containing both trivalent chromium ions and hexavalent chromium ions can be prepared while easily and assuredly adjusting the contents (content ratio) of trivalent chromium ions and hexavalent chromium ions to predetermined values (a predetermined value).

Abstract: A chromium plating method wherein an article to be plated is immersed in an acidic chromium electroplating bath and electrolysis is carried out using a positive electrode that has an iridium oxide-containing film at least on the surface. The acidic chromium electroplating bath contains a trivalent chromium compound and a hexavalent chromium compound at a ratio such that the total chromium concentration of trivalent chromium and hexavalent chromium is 60-140 g/L, the hexavalent chromium concentration is 5-40 g/L, and the ratio of the hexavalent chromium concentration is 5-35% by mass of the total chromium concentration, while containing 50-400 g/L of organic carboxylate ions and having a lead ion concentration of not more than 2 mg/L. By the method, a chromium plating film that is good and stable over a long time period can be obtained. In addition, the plating bath can be controlled extremely easily in the chromium plating method.

Abstract: An image processing apparatus, in which an operator can register a workflow with an easy operation, the usage of a routine task function can thus be facilitated, and the work efficiency of the operator can be improved. A plurality of functions for an image processing are provided with the image processing apparatus capable of executing a process including a combination of the plurality of the functions as a workflow. An operation unit receives an operation by an operator for the image processing apparatus. A storing unit stores the operation, which is received by the operation unit, by the operator as an operation history. An extracting unit extracts operation information for causing the workflow to be executed from the operation history stored in the storing unit. A registering unit registers the operation information extracted by the extracting unit.

Abstract: A control method for controlling a printing apparatus for printing an image according to image data includes displaying an image, specifying a type of a gesture according to a locus of coordinate information input by a user via an operation unit, detecting an area where the gesture is made, and performing print setting for printing image data according to the specified type of the gesture and the detected area.

Abstract: The invention provides a process for producing an alcohol-soluble urethane resin composition which is excellent in storage stability in an alcohol but which by adding water and a catalyst to the system during use, coating the mixture and drying the coating at ordinary temperature or by heating to allow a crosslinking reaction to proceed, thereby forming a film, is capable of obtaining excellent characteristics required for applications when used for, for example, synthetic leathers or artificial leathers, polyurethane porous bodies, moisture-permeable films and the like, such as solvent resistance (for example, alcohol resistance), chemical resistance (for example, DMF resistance), heat resistance, elongation and the like. Also, the invention provides a polyurethane porous body or a moisture-permeable film using a urethane resin composition obtained by the foregoing production process.

Abstract: A folder or a file managed in a document management apparatus includes a document with a high confidentiality or personal information, on which only a specific user has an access right. These are frequently stored in a personal folder, and there is a problem that the file or the like within the personal folder cannot be accessed at all when a user account has been deleted because of user's transfer or the like. When a user account has been deleted, the file, on which a user, the user account of whom has been deleted, has the access right, is encrypted and stored in a common area. The user is informed of a guest account for accessing the common area, a password for decrypting the encrypted file and the like. The former user can obtain the file by logging-in to the document management apparatus using the guest account.
