Abstract: A method for scanning bad block of a memory and a circuit system are provided. In a procedure of scanning bad blocks of the memory, the circuit system uses a cache read command to be adapted to a process of continuously reading a plurality of pages of the memory. The cache read command loads a page data to a cache of the memory in advance, and then read the page data from the cache at a next instruction cycle. Next, the cache read command loads a next page data to the cache again. These steps are repeated until the procedure of scanning bad blocks of the memory is completed. The method can effectively reduce the time for the memory to prepare the next page data so as to reduce the impact of the busy time of the memory on time performance.

Title: Tap with a permanent magnet
Inventor: RADOVANOVIC PREDRAG
IPC: F16K7/17
Filed: 2006-06-07
Abstract: Lever (1) set outside a housing (12) turns around the axis of the axle (5) and therein are permanent magnets (2) set parallel to the permanent magnets (3) of the rotor (4) and toward them by different poles are turned. Turning the lever (1) wherein are permanent magnets (2), turns the permanent magnets (3) of the rotor (4) with an axle (5) and a spindle (6) axially moved by a shutter (7). The shutter (7) at opening is moved and opens a hole (10) thus the fluid above the membrane (9) leaks into the hole (10). The fluid pressure above the membrane (9) decreases in relation to the pressure of fluid in the pipeline, thus the membrane (9) rises under the pressure of fluid from the pipeline and the fluid goes through the sewage (14). To achieve a complete tight seal at the membrane (9) there are apertures (11) for balancing the pressure, hence the closure (7), closes the tap under pressure of fluid from the pipeline and axial force generated by turning the spindle (6), thus the pressure inside the tap remains the same.
