Title: Data memory for computer
Inventor: HATAKEUCHI TAKAAKI
IPC: G06F12/02
Filed: 1988-11-18
Abstract: PURPOSE:To improve the processing speed for the editing, transfer, etc., of data by changing the address AD relative value corresponding to the AD where data are added or deleted when the data stored in a data memory are edited. CONSTITUTION:The count number of a counter 3 is kept at 0 while the counter 3 gives the accesses to the data on real AD 0-2 of a data memory 1. Therefore an access AD to be designated is equal to a real AD. Then +2 is given to the counter 3 from a relative AD memory 2 after an access is given to the data 2. At a subsequent access, +2 is given to an access AD 3 outputted from an auxiliary memory. Thus the AD 3 is equal to 5. The counter 3 keeps the integrated count value +2 until the new AD relative value is added after the access of a real AD 5. Thus the real AD is equal to the value obtained by giving +2 to an access AD. Thus the data following the real AD 5 receive the continuous accesses. In a data transfer mode is stored data can be read out with high efficiency regardless of the data storing state of the memory 1.

Abstract: PURPOSE:To miniaturize an iron powder separator body 1 for removing magnetic substance 24 with a high efficiency. CONSTITUTION:A rotating shaft 6 is rotated by an electric motor 5. Worm gears 8, and magnet parts 14, 14 which rotate and support the rotating shaft 6 through the worm gears 8 are synchronously rotated in the same direction. Magnetic substance 24 in oil 22 of a hydraulic tank 20 are attracted to the outer peripheral surface of the magnet parts 14 by the magnetic field of the magnet parts 14. By the rotation of the magnetic parts 14 having multiple pole in the peripheral direction, the attracted magnetic substance 24 are transferred to the adjacent magnet parts in order by the magnetic filed caused by opposite different magnetic poles between the adjacent magnetic parts 14, 14. By the magnetic poles 14a, 14b of the adjacent rotating magnetic parts 14, the magnetic substance 24 are attracted and transferred to a spring part 18 which the magnetic poles 14a, 14b continuously undergo a change in polarity to magnetize and rotate. By the rotation of the magnet parts 14 and the spring part 18, the magnetic substance 24 are stripped off in a nonmagnetized state when the magnetic pole of the spring part is reversed, and removed into a discharge part 25. In case the magnetic substance 24 are relatively large, the spring part 18 are made to undergo elastic deformation to pass them, allowing them to be stripped off and removed.
