When an online storage service is used to expand a storage capacity of a file server, an amount of communication in synchronization processing and an amount of data retained on the online storage service are reduced to save an amount of charge. In a kernel module provided with a storage area on the online storage service, files are divided into block files and managed, and blocks overlapping with an already registered and saved block file group are not uploaded, but only configuration information of the files is changed. A mechanism is adopted, in which DBs for managing meta information and elimination of duplication are divided and managed, and only updated sections are appropriately uploaded.

Information management method, and computer for providing information

Provided is an atomizer-equipped combustion apparatus including an atomizing device for atomizing a fuel, a spray chamber for mixing the fuel atomized by the atomizing device with air to form a mixture, and for moving the mixture downwardly toward an opening at a distal end portion of the spray chamber, and a wind box provided so as to surround a lower portion of the spray chamber for forming a combustion space between itself and the spray chamber, the wind box being provided with a plurality of air supply holes facing a lower portion of the spray chamber. A mixture of external air and a fine spray of fuel produced by the atomizer can be ignited instantaneously by means of a comparatively simple structure, odors produced at igition and extinguishment can be greatly suppressed and a high turn-down ratio can be obtained.

Combustion apparatus with atomizer and method of controlling same

An ultrasonic vibrator horn for use with ultrasonic atomizing apparatus for atomizing liquids, such as liquid fuels, employed in gasoline engines, diesel engines, gas turbines and various combustors such as industrial, commercial and domestic boilers. The ultrasonic vibrator horn has a body portion connected at one axial end thereof to an ultrasonic vibration generating means. The other axial end of the body, at which atomization of liquid material fed to the horn takes place when the horn is driven by the vibration generating means, is of conical shape. The body has at least one external groove formed in it. The groove communicates with the conical end of the body for receiving the liquid material and directing it to the conical end.
