Patent number: 6713725Abstract: In the head-fixing apparatus of the film heating system in an image forming apparatus, a heat capacity is controlled to be as small as possible because the quick-start property is recognized to be more importance. Thus, heat conductivity in the longitudinal direction is poor and, due to a relationship between the area where a recording material is conveyed and the heating area of the energizing heating resistance layer, a) heat is insufficient at the end portion in the initial period and b) unusual temperature rising occurs at the end portion at the time of continuous heat-fixing. In order to resolve those problem, an apparatus which can control adequately temperature at the area where a recording material is conveyed without rising temperature at the end portion of a heater as a non-sheet passing area.Type: GrantFiled: March 11, 2002Date of Patent: March 30, 2004Assignee: Canon Kabushiki KaishaInventors: Satoru Izawa, Yuko Tanaka, Shinji Hashiguchi

Patent number: 6480732Abstract: First and second volume data are collected in advance for the same region of a human body under examination. By performing volume rendering along the set direction of line of sight, a composite image of a first three-dimensional image based on the first volume data and a second three-dimensional image based on the second volume data is produced. The volume rendering is performed taking into consideration whether the trimming of the front region has been specified or not. In the volume rendering, by setting the initial position of a point of interest on the plane of projection or on the plane section indicated by a depth map according to whether the trimming of the front region has been specified or not, a three-dimension imaging region is varied. When the trimming of the front region has been specified, the initial position of the point of interest is set on the plane of projection.Type: GrantFiled: June 30, 2000Date of Patent: November 12, 2002Assignee: Kabushiki Kaisha ToshibaInventors: Yuko Tanaka, Hitoshi Yamagata

Patent number: 6456804Abstract: In the conventional types of Active Transfer Voltage Control (ATVC) system, it is assumed that transferring material has definite impedance. When a toner image is transferred to the transferring material which is in a condition where only the top of the transferring material has high impedance, the conventional ATVC system maintains a transferring current higher than the critical transferring current value with the top of the transferring material and applies a bias voltage at a corrected level, whereby the ATVC system may supply an excessive current to a portion of the photosensitive drum corresponding to a location which is other than the top having the high impedance and at which a toner image is not formed. Therefore, it is provided, an image forming apparatus which is capable of favorably transferring a toner image regardless of impedance of a transferring material.Type: GrantFiled: December 29, 2000Date of Patent: September 24, 2002Assignee: Canon Kabushiki KaishaInventors: Satoru Izawa, Yuko Tanaka, Norihito Naito
