Film deposition apparatus and film deposition method

The present invention is a film deposition apparatus configured to deposit a film on a substrate that has been loaded into a vacuum container via a transfer opening and placed on a table in the vacuum container, by supplying a process gas to the substrate from a process-gas supply part opposed to the table under a vacuum atmosphere, while heating a table surface of the table, the film deposition apparatus comprising: an elevating mechanism configured to vertically move the table between a process position at which the substrate is subjected to a film deposition process, and a transfer position at which the substrate is transferred to and from an external transfer mechanism that has entered from the transfer opening; a surrounding part configured to surround the table with a gap therebetween, when the table is located at the process position, so that the surrounding part and the table divide an inside of the vacuum container into an upper space, which is located above the table, and a lower space, which is located below the table; a vacuum exhaust conduit in communication with the upper space, through which a process atmosphere in the upper space is discharged to create a vacuum in the upper space; a heating unit configured to heat a gas contact region ranging from the upper space to the vacuum exhaust conduit, to a temperature higher than a temperature allowing adhesion of reactant; and a heat insulation part disposed between the heating unit and a lower part of the vacuum container surrounding the lower space.

Method and apparatus for automatic downloading of URLs and internet addresses

A bookmark transfer mechanism allows a user to transfer bookmark information from a primary computer to an alternate computer to customize a bookmarks menu on a web browser displayed on the alternate computer. The alternate computer prompts the user for a base address which is used by the web browser on the alternate computer to locate the primary computer where bookmark information is stored. The base address should correspond to a primary computer that has been configured for automatic download of bookmark information. Once the primary computer is located, the alternate computer transfers the base address and prompts the user for security information. The alternate computer then delivers the security information to the primary computer. The primary computer then authenticates the security information. If the security information is not valid, the primary computer delivers an error message to the alternate computer indicating that access to the primary computer has been denied. If the security information is valid, the primary computer transfers the bookmark information to the alternate computer. If necessary, the alternate computer translates the received bookmark information to the proper web browser format and updates the bookmarks menu on the web browser to include the transferred bookmark information. The bookmark information may be either temporarily or permanently incorporated into the web browser.

Apparatus and methods for transferring database objects into and out of database systems

Techniques for transferring objects between database systems. As implemented in a relational database management system, the techniques employ a data transfer mechanism that operates under control of a master table in the RDBMS that is performing the transfer operation. The master table specifies the kind of transfer operation to be performed, a set of objects to be transferred, operations to be performed on the objects as they are being transferred, and filters for selecting a subset of the objects. During execution of the transfer, the transfer mechanism maintains and updates state in the master table such that queries may be made on the master table to determine the current status of the operation and such that the transfer mechanism may restart the operation after it has been stopped either at the request of a client that is performing the operation or because of an error in the transfer. The master table's persistence and the status information it contains permit the client that is performing the operation to detach from the operation without stopping the operation and later again attach to the operation to determine the operation's status or to perform operations such as creating new files for the operation or changing the degree of parallelism with which the transfer operation is being performed. Another feature of the transfer mechanism is using an object's metadata to determine the most efficient way of transferring the object.

Apparatus and methods usable in connection with dispensing flexible sheet material from a roll

A powered dispenser for dispensing individual sheet segments from a continuous roll of sheet material provided with spaced tear lines comprises a powered feed mechanism, a releasable, powered drive mechanism, a powered transfer mechanism, a pair of web sensing sensors, a capacitive sensing system providing automatic sensitivity adjustment, and control circuitry. A dual power supply system provides a mechanical lock-out functionality, and the control system is protected from electrostatic build-up on the surface of the feed roller. The web sensor, and an antenna plate of the capacitive sensing system, are provided on respective printed circuit boards mounted in overlying relation. Utilizing signals received from the pair of web sensors and the capacitive sensing system, the control circuitry senses the presence of a user to activate the powered drive mechanism, and prevents further dispensing of the sheet material until a previously dispensed segment is separated from the roll. The web sensors detection of a leading edge of the sheet material initiates a predetermined interval of sheet material advancement providing a proper placement of successive tear lines. Various approaches may be utilized to accommodate inadvertent sheet “tabbing” scenarios. The web sensors, together with the control circuitry, are also used to detect the depletion, or absence, of a working roll of sheet material, whereupon the control circuitry controls the powered transfer mechanism to automatically transfer the web feed supply from a depleted working roll to a reserve roll. The powered transfer mechanism may include a motor driven transfer bar, or provide motor driven release of a spring biased transfer bar. Another arrangement allows for ready release of a roll core, and drop of the same into an open dispenser cover for removal.

Power generating system

This invention overcomes the disadvantages of the prior art by providing a power generating system particularly suitable for field use in remote locations, which is fuel-efficient, relatively quiet, tolerant of dust, capable of operating on low grade logistics and diesel-like fuels and capable of generating between 500 W and 2 KW of continuous electrical power. This generator employs a miniature internal combustion engine/generator (MICE) having a piston moving within a cylinder arranged for two-cycle operation, and an interconnected, axially arranged piston shaft that oscillates an alternator coil within a magnetic core. The piston shaft is opposed by a strong, multiple-helix spring. The cylinder head, in which the piston operates, is cooled by moving (electrically pumped) fluid in a cooling head, or by another heat-transfer mechanism. The MICE generator's intake arrangement includes a preheater heated by a heated fluid flow thereon. The MICE generator is vibration-isolated using a base that supports the MICE on a plurality of soft coil springs. The MICE generator is encased in an acoustic enclosure having a shell composed of sheet metal or another stiff material extending from the base plate and being covered by a top side. Holes in the enclosure top are covered by porous discs that allow exhaust gasses from the internal muffler to pass therethrough. The acoustic enclosure resides in a large, typically portable, external package enclosure.
