Automated recovery from raid double failure
Occurrence of a RAID double failure in a slice of a RAID protection group (failed slice) renders data stored in the back-end tracks of the failed slice vulnerable to loss. When a RAID double failure is detected, a new slice is added to the RAID protection group. Front-end tracks that map to the good back-end tracks of the failed slice are moved from the back-end tracks of the failed slice to the back-end tracks of the newly added slice. Any front-end tracks that mapped to the bad back-end tracks of the failed slice are made to be write pending and written to corresponding back-end tracks of the newly added slice. Front-end tracks that map to the bad back-end tracks may be made to be write-pending in connection with a host write operation, by reading the front-end tracks from a local backup, or from a remote backup location. |

Washing machine
A washing machine includes a dewatering shaft for rotating a washing tub, a drive shaft for rotating a pulsator in the washing tub, a coupler configured to move along the dewatering shaft to couple or decouple the drive shaft and the dewatering shaft, a solenoid configured to move the coupler, and a coupler guide configured to be rotated by contact with the coupler or to maintain the coupler in the second position. The coupler includes locking protrusions configured to lock onto an upper side of the coupler guide. The coupler guide includes first guide projections disposed on an outer perimeter of the coupler guide and configured to contact one of the locking protrusions to rotate the coupler guide, and second guide projections disposed opposite to the first guide projections and configured to contact another of the locking protrusions to rotate the coupler guide. |

Weft thread cutting device looms without shuttles
A weft thread cutting device for shuttleless looms is placed between a fabric edge, a comb and a warp mouth, on one side, and a weft thread selector, on the other side. Weft threads, coming from a plurality of eyelets, join at a vertex located at the fabric edge and at the beating line of the comb. The weft thread cutting device has a rotating disk with a cutting edge, configured to cut the weft threads by a motor which keeps the rotating disk in rotation, and a step control motor, which, through a rotating shaft provided with an eccentric, controls motion of a hinged lever swinging with respect to a longitudinal axis of the step control motor. The hinged lever is shaped, at one end, in the form of two arms, respectively resting on the surfaces of two elastic plates, and is connected, at the other end, to the eccentric. |

Electrodeposition coating facility
The amount of wash water to be consumed in an electrodeposition coating facility and the amount of used wash water to be discharged that requires post-treatment are reduced. To achieve this object, an electrodeposition coating facility that includes a degreasing process section A, a post-degreasing rinse section B, a chemical conversion process section C, a post-chemical-conversion rinse section D, an electrodeposition coating section E, and a post-electrodeposition rinse section F is provided with a filtration process apparatus 4 and a wash water recycling line 5. The filtration process apparatus 4 performs a filtration process on wash water W after being used to wash an object to be coated 1 in the post-electrodeposition rinse section F. The wash water recycling line 5 feeds, to the post-chemical-conversion rinse section D, the wash water W after being subjected to the filtration process in the filtration process apparatus 4 as wash water W to be used to wash an object to be coated in the post-chemical-conversion rinse section D. |
