Abstract: PURPOSE:To realize an R-Fe-B permanent magnet which has a remarkably large coercive force and residual magnetic flux density and a great mechanical strength by maldistributing Dy and Tb near the grain boundary at the specified ratio and by holding the oxygen content down within the specified range. CONSTITUTION:The main ingredients of this magnet are R (R is one or more kinds of rare earth metal elements containing Y), T (T is Fe, Fe or/and Co) and B. The relation among the Tb content TbC and Dy content DyC, in the central part of a crystal grain and the Tb content TbB and Dy content DyB near the grain boundary of the crystal grain is shown by (TbB+DyB)-(TbC+ DyC)>=0.2(%). The oxygen content is 5000ppm or lower. The values of TbC and DyC and the values of TbB and DyB are found by cutting the magnet, polishing the cutting plane and then measuring the content of each element in the central part of the crystal grain and near the grain boundary inside the crystal grain about a square region of the side length 10mum or above in the cutting plane.

Filed: 1988-11-08
Abstract: PURPOSE:To eliminate the decalcomania paper pulling and removing process with damage and make the next paper feeding operation smooth by driving a feed roller for rotation for a certain time when the residual paper is detected in a paper separating and feeding part at the time of recovery-mode. CONSTITUTION:When a jam is generated in a copying machine, the operation of the copying machine is stopped to wait the disposal of the jammed paper. After the jammed paper is disposed and an operating key is pushed, the recovery-mode for automatically exhausting the residual paper in a carrying passage is carried out so as to reduce the burden of the jam disposal by a user. At this stage, when the residual paper is detected in the paper separating and feeding part, a feed roller 27 is driven for rotation for a certain time. The residual paper is thereby fed to grip rollers 40, 41, and thereafter, the residual paper is exhausted by the recovery-mode disposal. As a result, the decalcomania paper pulling and removing process with damage is eliminated, and the next paper feeding operation can be performed smoothly.

Filed: 1991-10-01
Abstract: PURPOSE:To prevent the multiple use of the I/O resource by a plurarity of CPUs by providing a function turning the content of the memory cell to the prescribed state after reading out the data of the selected memory cell at the time of data reading. CONSTITUTION:When a RAM is used as a semaphore memory 20 of a multiprocessor system, the content of the memory cell is rewritten to '1' in the same cycle after data reading when CPUs 11 to 13 access to the RAM. Therefore, a semaphore flag '0' is not read out by the other CPU during the time and '1' is read out when the other CPU reads the semaphore after the read cycle. With the RAM, the memory write cycle is performed after the memory read cycle so that the arbitration control of the I/O resource of the multiprocessor system can be performed regardless of the type of CPU even when the TAS command is not used.
