Inventor: MISAWA TAKASHI
IPC: B24B19/02
Filed: 2002-10-30
Abstract: <P>PROBLEM TO BE SOLVED: To manufacture a workpiece with a plurality of regularly arranged regular quadrangular pyramidal projections by reducing wear of a grinding wheel.  <P>SOLUTION: The workpiece with the plurality of regularly arranged regular quadrangular pyramidal projections is manufactured by forming m V-grooves on the surface of the workpiece by performing stroke grinding for a planar workpiece, while cutting the planar workpiece by lowering the grinding wheel 3 elevatable in a vertical direction to a horizontal surface on the surface of the planar workpiece fixed to a rotary table 6 in an inclined state by 45° to the horizontal surface, and forming n V-grooves again by performing stroke grinding for the planar workpiece, while cutting the planar workpiece by lowering the grinding wheel 3 on the surface of the planar workpiece formed with the V-grooves fixed to the rotary table 6 in an inclined state after rotating the rotary table 6 by 90°. As a result, wear of the grinding wheel is reduced and the service life is lengthened.  <P>COPYRIGHT: (C)2004,JPO

Title: Image forming apparatus and image forming method
Inventor: NAKAMURA MASAHIDE
IPC: G03G15/01
Filed: 2002-10-30
Abstract: <P>PROBLEM TO BE SOLVED: To realize satisfactory both-sided printing as well as simple transfer control, in an image forming apparatus and image forming method for both-sided printing.  <P>SOLUTION: Four toner images of respective colors are superposed one on the other on the surface of an intermediate transfer belt 41 and thereby a full-color toner image is formed. As an intermediate transfer belt 41 is rotated, the toner image is conveyed to a secondary transfer position 49 between rollers 45 and 48 and transferred to a recording medium 4. After the transfer, the recording medium 4 is conveyed along a specific conveyance path 5, and the toner image is fixed to the recording medium 4 by a fixing unit 60 in which a fixing temperature is set to 100°C or less. Setting the fixing temperature to 100°C or less restricts a change in the characteristic of the recording medium 4 which results from a fixing process. In addition, conditions under which transfer is performed in transfer (pre-transfer) of a toner image to the surface of the recording medium 4 are the same as those in transfer (post-transfer) of a toner image to the back of it.  <P>COPYRIGHT: (C)2004,JPO
