IPC: G06F3/06
Filed: 1989-12-14
Abstract: PURPOSE:To make it possible to simultaneously drive a CPU and a secondary storage device by preparing a local memory to be accessed from both CPU and secondary storage device in each block unit in addition to a main storage. CONSTITUTION:When the secondary storage device 6 is accessed, a chain is disconnected from free buffer chains and connected to the has chain shown in a diagram and then a block number indicated on a header is set up in a selector 5 to start the device 6. The started process is turned to a waiting state and another process runs. Since the other process can occupy a bus even during the data transfer of the device 6, the running process can continue operation. If a required data block is present on the hash chain when a another process simultaneously accesses the device 6, the process is not waited by setting up the block memory number indicated on the header on the selector 3 to be operable. Consequently, the data transfer of the secondary storage device 6 and the execution of the CPU 1 can be simultaneously executed.

Title: Cyclic magnetic field generating device
Inventor: KONO EIICHI
IPC: H01J23/10
Filed: 1988-12-21
Abstract: PURPOSE:To reduce labor of adjusting the on-axis mag. field distribution by changing the size of a pole piece in the radial and/or axial direction. CONSTITUTION:A plurality of ring-shaped permanent magnets 1 are piled in the axial direction with a pole piece 21 interposed one by one so as to form a periodic mag. field generating device 3. The mag. field acting on the axis of the device will decrease as the thickness of the body 21A of the pole piece 21 enlarges, and increases as it lessens. In case the size of pole piece 21 in its radial direction is increased or, decreased, the mag. field intensity acting on the axis can be adjusted. Thus the on-axis mag. field distribution is adjusted simply by changing the size of pole piece in its axial and/or radial direction, compared to the adjusting method in which the magnetic force of each permanent magnet is varied.
