Title: Method and apparatus for reading a multi-level passive element memory cell array
Inventor: SCHEUERLEIN ROY E
IPC: G11C16/08
Filed: 2007-07-31
Abstract: A four level passive element cell has memory states corresponding to decreasing resistance levels, which are preferably mapped respectively to data states 11, 01, 00, and 10. The LSB and MSB are preferably mapped as part of different pages. To discriminate between memory cell states, the selected bit line current is sensed for at least two different combinations of reference current level and read bias voltage. A mid-level reference is used to read the LSB. When reading the MSB, a first reference between the 10 and 00 data states, and a second reference between 01 and 11 data states may be used, and the mid-level reference need not be used. In certain embodiments, the bit line current may be simultaneously compared against the first and second references, without requiring a delay to stabilize the bit line current to a different value, and the MSB generated accordingly.

Title: Continuous variable transmission regulating/controlling method for grinding wheel of grinder
Inventor: JU YI-CHENG
IPC: B24B49/12
Filed: 2007-12-19
Abstract: A continuous variable transmission regulating/controlling method for a grinding wheel of a grinder comprises the following steps: providing a grinder; measuring an initial distance; setting an initial position #101 of the grinding wheel; setting the coordinate system of an initial workpiece; setting the sectional difference separation value; and starting the grinder and executing the program. After starting the grinder, the grinding wheel shifts toward the workpiece to perform the grinding. An optical ruler detects the dynamic distance L'between the grinding wheel and the workpiece surface and the dynamic diameter D'of the workpiece, and sets the sectional difference separation value S so as to execute a program (L'+D')-#101=E and E/S=E'. If the E'value is greater than 1, the servomotor is automatically up-regulated to the second stage rotation speed. If the E'value is greater than 2, the servomotor is automatically up-regulated to the third stage rotation speed. Accordingly, the rotation speed of the grinding wheel can be adjusted automatically based on the abrasion degree of the grinding wheel to allow the grinding wheel keeping a stable cutting degree and to avoid the shortcoming caused by the manual setting error.
