Abstract: The present invention discloses a novel flexible spray nozzle sprayer face cap, rotatably installed at a head part of a garden water gun, configured to switch sprayed water types and structurally including a water division plate, a spray seat, and a main body sequentially fixed in a coaxial way. The novel flexible spray nozzle sprayer face cap is mainly characterized in that an embedded and fixed flexible spray nozzle is disposed in each water outlet small hole formed in the main body, and an outer end of each of the flexible spray nozzles respectively extends out of the water outlet small hole to be exposed, so that when the sprayer face cap rotates and switches to communicate passing water to a plurality of water outlet small holes, the passing water can be sprayed out from the flexible spray nozzle in each of the water outlet small holes.

Abstract: The present invention discloses an integrated new technique and apparatus for recycling volatile organic compounds of coating printing. The new technique collects a mixed gas of volatile organic compounds produced in the process of coating and drying of a coating machine with a volatiles collecting hood of coating machine, compresses and lead the mixed gas of volatile organic compounds into a condensation system for condensation; the obtained condensate enters a gas-liquid separator to obtain a coating solvent with high concentration; non-condensable lean gas enters a membrane separation and enrichment system to obtain a mixed gas of high concentration organic compounds after membrane separation and enrichment with a complete set of membrane assembly, and then returns to front of the condensation system to repeat the integrated technique.

Abstract: A method uses a record of I/O priorities in a determination of a storage medium of a hybrid storage system in which to store a file. The method maintains the record of I/O priorities by assigning an I/O temperature value to each request for access to the file based upon an I/O priority level of the process making the request. The method marks the file as hot if the file temperature value is greater than a threshold value. The method stores files marked as hot in a lower latency storage medium of the hybrid storage medium.

Abstract: A method for monitoring and managing virtual machine image storage in a virtualized computing environment is proposed, where the method for managing storage utilized by a virtual machine can include identifying one or more unused disk blocks in a guest virtual machine image, and removing the unused disk blocks from the guest virtual machine image.

Abstract: A method and apparatus are provided for pre-allocating non-initialized blocks of data in a file system. Each file contains a primary i-node to maintain file metadata. A secondary i-node is created and associated with the primary i-node. The secondary i-node contains non-initialized data blocks, and the primary i-node contains valid and initialized data blocks. A write operation to a non-initialized data block in a pre-allocated range stored in the secondary i-node directs the data block from the secondary i-node to the primary i-node.
