Title: Administration and utilization of private keys in a networked environment
Inventor: EPSTEIN MICHAEL
IPC: H04L9/32
Filed: 1999-01-28
Granted: 2001-04-11
Abstract: In a public key cryptosystem, the private keys of users, as encrypted with a symmetric algorithm by using individual user identifying keys, are stored at the server end along with the users' respective public keys. The server uses an ID of a user transmitted to it from user equipment to read the stored encrypted private key and the public key of the user. The encrypted private key is then transmitted via the network to the user equipment and, locally, at the user equipment the received encrypted private key is decrypted using the user identifying key. The user identifying key may be determined at the user equipment by hashing either the user's passphrase, which is entered by the sure, or the user's biometric information (fingerprint, voice print, retina scan, or face scan). The private key is sent to the user equipment only when needed and, after use, the private key and user identifying key are not retained at the user equipment.

Granted: 2001-12-01
Abstract: A method and apparatus for processing semiconductor workpieces, or a component adapted for use in such apparatus, wherein a component surface is textured so that process byproduct material deposited on the textured surface will have improved adhesion. The dimensions of the texturing according to our invention are much greater than the dimensions of the texturing conventionally produced by conventional bead blasting. The improved adhesion enables a thicker layer of material to be deposited on the textured surface without risk of the material flaking off. Consequently, the invention enables the chamber to operate a longer period of time before it must be shut down to clean or replace the chamber wall or lining.

Abstract: A movable partition wall, with a simple structure and without working on a structural frame body and a panel, can form a wiring passing unit for allowing a wiring space formed between the structural frame body and the panel to communicate with the outside of the structural frame body. The front-to-rear width of a horizontal frame member (24) is made larger than that of a side frame member (26). The front-to-rear faces (24a) of a horizontal frame member (24) are used as panel attaching faces (P), or a panel attaching member (8) is mounted on a structural frame body (B2), so it could raise the position of a panel attaching face (8a) to a position projecting outward beyond the front-to-rear face (21a) of a side frame member (21). Therefore, it separates the inner face (3a) of a panel (3) from the front-to-rear faces (26a, 21a) of the side frame members (26, 21), by a wiring passing unit (5) for allowing a wiring space (S) to communicate with the outsides of the structural frame bodies (A2, B2). The wiring passing unit (5) is formed between the inner face (3a) of the panel (3) and the front-to-rear faces (26a, 21a) of the side frame members (26, 21).

Title: Device for feeding hard-gelatin capsules to a capping machine
Inventor: TREBBI ROBERTO
IPC: A61J3/07
Filed: 2000-10-16
Granted: 2001-12-11
Abstract: Respective secondary thrusters (70, 71) are added to the primary horizontal thruster (7) and primary vertical thruster (12) of a guiding device of the known type and the guide channel (6) is provided with dimensions such that the steps of guiding and feeding the capsule (C) are performed with minor successive displacements of the said capsule (C). The primary vertical thruster (12) operates, in a position distant from the sleeve (13) of the capping machine so as to allow discarding and free removal of the defective capsules (C) which have a double lid (C2) or the capsule parts which reach this thruster. The last section (206) of the guide channel (6) inside which the secondary vertical thruster (71) operates, has a width slightly smaller than that of the upstream section (106) of the said channel so as to retain firmly the end of the defective capsule (C) having lids (C2) on opposite ends of a base (C1). Such a defective capsule (C), which is arranged horizontally or inclined by the primary horizontal thruster (7), is then acted on by the tip (112) of the primary vertical thruster (12) and by a face (171) of the secondary vertical thruster (71) which discard this defective capsule (C) from the bottom of the guide channel (6). On the other hand, a capsule (C) correctly fitted with a lid (C2) and oriented vertically by the primary vertical thruster (12) remains inside the guide channel (6), is then displaced inside the latter by the secondary horizontal thruster (70) and then a leading face (271) of the secondary vertical thruster (71) acts on this capsule and accompanies the said capsule (C) during the complete stroke for insertion inside the sleeve (13) of the capping machine.

Title: Non-interrupt recording/playing video/audio method and system
Inventor: SUEN JIUN-YI
IPC: H04N5/765
Filed: 2000-10-18
Granted: 2003-03-21
Abstract: A non-interrupt recording/playing video/audio method and the system using the same are disclosed in the present invention. In the recording operation, when the primary storage medium is full of the video/audio data, the controller orders the buffer memory to continue the storing action so as to store the video/audio data inside the buffer memory temporarily. After the primary storage medium is changed, the controller makes the primary storage medium accelerate the storing operation so as to accelerate the storage of the video/audio data, which is temporarily stored in the buffer memory originally, into the primary storage medium till the normal real-time synchronous recording speed is recovered. Therefore, the recording operation is not interrupted due to the change of the primary memory. In the playing operation, the controller accelerates the pre-storing operation of constant amount of video/audio data from the primary storage medium in advance inside the buffer memory. In addition, the buffer memory plays the video/audio data with a normal speed. After the video/audio data of the primary storage medium is completely transferred and stored inside the buffer memory ahead of time, another primary storage medium is changed to continue the pre-storage of video/audio data inside the buffer memory before the playing of buffer memory is not completed such that the playing operation is not interrupted due to the change of primary storage medium.

Abstract: A semiconductor memory device including a delay locked loop (DLL) capable of operating at high frequency in a burn-in mode, and a method of operating the DLL, are provided. The semiconductor memory device includes a ring oscillator which operates in response to a burn-in mode signal; a DLL control signal generation circuit for activating DLL control signals in response to the burn-in mode signal; and the DLL which operates in response to the output of the ring oscillator and the DLL control signals. In contrast to a conventional technique where burn-in evaluation of the operation of a delay locked loop is difficult due to a clock frequency which is not sufficient for testing a delay locked loop upon burn-in test, in the present invention, high frequency clock signals provided from the ring oscillation unit are generated in response to a burn-in mode signal, so that the original operation of a delay locked loop can be tested.

Granted: 2002-03-01
Abstract: A variable conductance device [10, 20, 100] having a first source region [11, 21, 111] and a first drain region [14, 23, 114] in a semiconductor substrate. A first channel region connects the first source and the first drain regions. A first resistive layer [13, 22] overlies the first channel region and has first and second electrical contacts [15, 16, 25, 26] spaced apart from one another thereon. The conductance of the path between the first source region [11, 21, 111] and the first drain region [14, 23, 114] depends on the current flowing between the first and second electrical contacts [15, 16, 25, 26]. By adding a FET [216] having its gate and source shorted together to the variable conductance device [10, 20, 100], a device having the current gain characteristics of a bipolar transistor is obtained. The first drain region [14, 23, 114] is connected to the drain of the FET and the source of the FET is connected to the second electrical contact. The precise form of the current transfer function can be altered by connecting a number of variable conductance devices [10, 20, 100] according to the present invention in parallel.
