Granted: 2006-03-02
Abstract: A content key, an authentication key, and a program data etc. are transmitted with an enabling key block (EKB) in an encrypted key constitution of a tree structure. The EKB has a constitution in which a device as a leaf of the tree holds a leaf key and a limited node key, and a specific enabling key block (EKB) is generated and distributed to a group specified by a specific node to limit devices that can be renewed. As the devices that do not belong to the group cannot perform decryption, the security for distributing keys etc. can be secured. Thus, distribution of various kinds of keys or data is executed in an encryption key constitution of a tree structure to realize an information processing system and method enabling to distribute data efficiently and safely. <IMAGE>

Abstract: Abstract of the Disclosure METHOD FOR FORMATION OF AN ISOLATING OXIDE LAYER          In a method for the formation of an isolating oxide layer on a silicon substrate, an anti-nitridation layer is formed on a silicon substrate at locations where isolating oxide is desired.  The anti-nitridation layer has openings therethrough which expose the silicon substrate at locations where isolating oxide is not desired.  A thin silicon nitride layer is selectively grown at the locations where isolating oxide is not desired by nitridation of the exposed silicon substrate.  Isolating oxide is then selectively grown at the locations where isolating oxide is desired.  The thin silicon nitride layer inhibits oxide growth at the locations where isolating oxide is not desired. The method reduces "bird's beak" formation and is particularly applicable to high density IGFET devices.                             - i -

Granted: 1997-04-29
Abstract: A method to extract and recover plasticizers and their stabilizers from solid propellants, explosives, and pyrotechnics (PEP source compositions) employs near critical liquid (NCL) or supercritical fluid (SCF) CO2 as the solvent.

Abstract: METHOD OF ADAPTIVE CONTROL FOR CLOSED THROTTLE    DOWNSHIFT IN AN AUTOMATIC TRANSMISSION            ABSTRACT OF THE DISCLOSURE         In an automatic transmission, clutch-to-clutch closed throttle downshifting is controlled by filling the on-coming clutch at a maximum pressure command for a set period while commanding the off-going clutch pressure to a low value and exhausting the off-going clutch before the end of the fill period.  At the end of the fill period the on-coming pressure is set to an initial value and then ramped up until turbine speed is pulled up due to off-going clutch slippage.  Then a closed-loop profile control period starts wherein the slip of the on-coming clutch is measured and controlled to a slip profile.  When synchronization of the on-coming clutch is detected, maximum pressure is commanded.  Parameters for controlling the quality of a shift such as on-coming clutch initial pressure and on-coming clutch fill time are automatically adjustable during vehicle use to correct shift aberrations which degrade shift quality.

Abstract: An improved innerseal for sealing containers includes a body portion (22) having an upper surface and structure (24) connected to the upper surface for grasping by a user, whereby the body portion may be removed from a container quickly and efficiently. The body portion includes structure for preventing passage of fluid therethrough, and structure for bonding the body portion against the upper rim of the container with a first bonding force. The bonding structure has a first bonding portion for sealing against the container rim and a second bonding which is adhered to the first bonding with a second bonding force which is greater than the first bonding force. Consequently, a first part of the first bonding portion will delaminate from the second bonding portion over the container rim and re-main adhered to the rim, while a second part of the first bonding portion will remain adhered to the sec-ond bonding portion, thereby exposing the opening in the container when the grasping structure is pulled. A method for manufacturing containers so sealed is also disclosed.

Abstract: A platinum-silicon powder is electrophoretically deposited on a nickel or cobalt base superalloy substrate.  The deposited powder is heated to form a transient liquid phase on the  substrate and initiate diffusion of Pt and Si into the substrate.  An aluminum-chromium powder is then electrophoretically deposited on the Pt-Si enriched substrate and diffusion heat treated to form a corrosion- and oxidation-resistant Pt-Si enriched diffused aluminide coating on the substrate.  The presence of both Pt and Si in the aluminide coating unexpectedly improves coating ductility as compared to a Pt-enriched diffused aluminide coating without Si on the same substrate material.
