Abstract: In a pneumatic tire, a bead core has end portions in a tirewidth direction formed as vertical lines along a tireradial direction. A length of the vertical lines is from 20% to 30% of a core height. In two adjacent bead core layers of first, second and third layers, the radial outer layer tireincludes two or more bead cores more than the radially inner layertire, and a misalignment amount between the bead wires each at an end portion on one side in the tirewidth direction is one-half of a bead wire thickness.

Abstract: A non-volatile memory system separately performs a memory operation for multiple sub-blocks of a block in order from previously determined slowest sub-block of the block to a previously determined faster sub-block of the block. As a slower sub-block is more likely to fail, this order of is more likely to identify a failure earlier in the process thereby saving time and reducing potential for a disturb. In some embodiments, the proposed order of operation can be used in conjunction with a programming process that concurrently programs blocks in multiple planes using completion of programming of a fastest plane to a data state as a trigger to test for program failure of other planes to the data state.

Abstract: To prevent loss of data due to a word line to memory hole short (or another defect), it is proposed to perform an erase process for a plurality of memory cells, detect that a subset of the plurality of memory cells are slow to erase, and prevent successfully programming for at least some of the memory cells that are slow to erase. This technique uses the erase process to predict future word line to memory hole shorts and prevent programming of memory cells predicted to have a future word line to memory hole short so no data will be lost when the short manifests.
