Title: Soft-switching cell for reducing switching losses in pulse-width-modulated converters
Inventor: JANG YUNGTAEK
IPC: H02M3/28
Filed: 2000-03-27
Granted: 2002-02-01
Abstract: A circuit technique substantially reduces the switching losses of a pulse-width-modulated (PWM) converter caused by the turning-on (closing) and turning-off (opening) characteristic of the switch and the reverse-recovery characteristic of the rectifier. The losses are reduced by using a new switch cell which includes a snubber inductor, a clamp diode, a clamp capacitor, a main switch, and an auxiliary switch. The reverse-recovery-related losses are reduced by the snubber inductor connected in series with the main switch and the rectifier to control the rate of change of rectifier current during its turn-off. In addition, the main switch operates with zero-current and zero-voltage switching, while the auxiliary switch operates with zero-voltage switching. A proper operation of the proposed circuit requires overlapping gate drives of the main and the auxiliary switches. The circuit technique can be applied to any member of the PWM converter family.

Title: Electrode forming apparatus for electric parts
Inventor: CHIBA MINORU
IPC: H01G13/00
Filed: 2000-04-28
Granted: 2001-10-11
Abstract: An electrode forming apparatus for electric parts has a tape and a driving mechanism. The tape has holding holes for holding board-shaped electric parts therein at regular intervals and feeding holes for feeding the tape at regular intervals. The driving mechanism can feed the tape by engaging with the feeding holes of the tape. A pasting unit applies electric conductive paste to the electric parts held by the holding holes of the tape fed by the driving mechanism, in order to form a electrode. Each of the holding holes has a pair of abutting edges for abutting on both opposite surfaces of the board-shaped electric parts and at least one cutout portion formed from the abutting edges. Due to the above constitution, the board-shaped electric parts can be held and conveyed by the abutting edges of the holding hole. Thus, the pasting unit can apply the electric conductive paste to the predetermined areas of the electric parts more accurately.

Title: Internet-based shared file service with native PC client access and semantics and distributed access control
Inventor: PHILLIPS ROBERT S
IPC: G06F17/30
Filed: 2000-11-23
Granted: 2002-05-21
Abstract: A multi-user file storage service and system enable each user of a pre-subscribed user group to operate an arbitrary client node at an arbitrary geographic location, to communicate with a remote file server node via a wide area network and to access the files of the file group via the respective client node in communication with the remote file server node via the wide area network. More than one user of the pre-subscribed user group is permitted to access the file group at the remote file server node simultaneously. Illustratively, the integrity of the files at the remote file server node are maintained by controlling each access to each file at the remote file server node so that each access to files at the remote file server is performed, if at all, on a respective portion of each file as most recently updated at the remote file server node. Thus, all native operation system application programming interfaces operate as if all multi-user applications accessing the files function as if the remote server and client nodes were on the same local area network. Illustratively, and interface is provided for adapting file access one of the client nodes. The interface designates at the client node each accessible file of the group as stored on a virtual storage device. The interface enables access to the designated files in a fashion which is indistinguishable, by users of, and applications executing at, the client node, with access to one or more files stored on a physical storage device that is locally present at the client nodes. Illustratively, an encrypted key is transferred from the remote fileserver node to one of the client nodes via a secure channel. The key is encrypted using an encryption function not known locally at the remote file sever node. The transferred key is decrypted at the client node. The key is used at the client node to decrypt information of the files downloaded from the remote file server node or to encrypt information of the files prior to uploading for storage at the remote file server node. Access control to a particular one of the files of the group can be delegated to an access control node.

Title: Ion implantation ion source, system and method
Inventor: HORSKY THOMAS N
IPC: H01J27/20
Filed: 2000-12-13
Granted: 2003-02-21
Abstract: An ion source (1) for ion implantation system and a method of ion implantation employs a controllable broad, directional electron beam (32) to ionize process gas or vapor, such as decaborane, within an ionization volume (16) by primary electron impact, in CMOS manufacturing and the like. A controllable low-temperature vaporizer (2, 28) communicating via a high conductance path to the ionization chamber enables relatively gentle handling of feed materials, making possible novel use of numerous hydrides, dimer-containing compounds, and other temperature-sensitive materials. Isolation of the electron gun (12, 33, 34, Fig 4B, etc.) for producing the energetic electron beam and of a beam dump (11) to which the energetic beam is directed, as well as use of thermally conductive members and gas conduction for cooling the ionization chamber (5) and controlling the temperature of the vaporizer (2, 28), enable use of the system with large molecular species such as decaborane, and other temperature-sensitive molecules. Electron uptics systems, particularly multicomponent electron zoom lens systems (Fig. 10), and accel-decel arrangements (Fig. 18) facilitate extraction of electrons from an emitting surface and tailoring of the energy of the electrons and the size and shape of the beam to effectively ionize a desired volume of the gas or vapor that is located adjacent the extraction aperture (37). Structural arrangements and sizing of the components enables retrofit into volumes (60) occupied by other types of ion sources in existing ion implantation systems. Use of the same control interface of such systems by employing a configurable translator (Fig. 16A), enable dramatically improved performance of existing designs of the ion implantion systems. Demountable and replaceable ionization chambers and vaporizers and their crucibles, and numerous other important features, realize economies in construction, operation and maintenance. The usefulness of numerous materials not heretofore recognized as sources for ions has been discovered including Sb2O5, SbBr3, SbCl3, As2O3, P2O5, Indium I-Iydroxide and In2(S04)3 x H2O. Achievement of production-worthy operation in respect of very shallow implants is realized.
