    摘要： A process for manufacturing a rolling contact member comprises preparing a steel member consisting of a steel containing 0.7 mass % or more of carbon; performing hot forging of the steel member prepared in the steel member preparation step to thereby obtain a blank ring as the first forged member; performing turning of the blank ring obtained in the hot forging step to thereby remove part of the blank ring; and performing cold forging of the blank ring wrought in the first turning step to thereby obtain a stepped ring. In the steps subsequent to the cold forging step, on the stepped ring, the area wrought in the first turning step is not subjected to cutting.

    摘要： A process for manufacturing a rolling contact member that while simultaneously avoiding the problem attributed to generation of decarburized layer and the problem attributed to scale generation, attains reduction of manufacturing cost. The process comprises the steel member preparation step of preparing a steel member consisting of a steel containing 0.7 mass % or more of carbon; the hot forging step of performing hot forging of the steel member prepared in the steel member preparation step to thereby obtain a blank ring as the first forged member; the first turning step of performing turning of the blank ring obtained in the hot forging step to thereby remove part of the blank ring; and the cold forging step of performing cold forging of the blank ring wrought in the first turning step to thereby obtain a stepped ring. In the steps subsequent to the cold forging step, on the stepped ring, the area wrought in the first turning step is not subjected to cutting operation.

    摘要： In an image forming apparatus of the present invention, when performing one-side printing during a predetermined period after two-side printing, a change in a carrying velocity of a post-process apparatus is prevented and thus recording paper having passed through a fixing section is carried and output at a velocity that is lower than a velocity for normal one-side printing and that is identical with a velocity for two-side printing. Consequently, it is possible to prevent dropping of productivity of the image forming system due to a time necessary for changing the carrying velocity of the post-process apparatus and to increase an operating ratio of the image forming system, even if the post-process apparatus is designed to completely stop the carrying roller etc. when changing the carrying velocity.

    摘要： In an image forming apparatus, damage to the apparatus caused by power conduction at the time of installation is prevented. When initial adjustment at factory ends and service person moves the apparatus, a power switch is turned OFF. Using this OFF operation as a trigger, a control unit 100 reads specific information (information related to pre-processing before starting power supply to the apparatus), and displays the information on electronic paper 108.

    摘要： An LDAP server stores security levels individually assigned to a plurality of destinations and a plurality of users in advance. When a user is authenticated successfully by the LDAP server, a control section of a multi-functional machine obtains the security level of the authenticated user from the LDAP server via a communication section, and then restricts/relaxes display contents necessary in transmission processing, in accordance with the high/low of the security level. Further, when the security level is not lower than a predetermined threshold value, the control section obtains from the LDAP server a destination in which the user is adopted as the addressee.

    摘要： When a setting input through a control portion falls within the first setup range, the settings in the first setup storage are rewritten with the setting in the second setup storage. Since the setting was revised, the revision history including the setup content and the data of the setting is stored in a revision history storage. Next, a determination process for the revised setting is carried out. Specifically, it is determined whether a usually expected input setting from the control portion falls within the second setup range. When it does not fall within the second setup range, the controller determines that the input setting is not a proper value, and reads out the setting before revision, stored in the third setup storage to rewrite the settings in the first setup storage with it.
