Title: System and method for providing for secure encryptor key management
Inventor: COONEY HENRY G
IPC: G06Q20/38

Granted: 1993-05-18
Abstract: Abstract Of The Disclosure A system and method for storing encrypter keys in a secure manner to prevent a "debugger" or an unauthorized user of a user application from compromising the keys.  A static RAM with a battery support is used to store the keys after they are installed therein by a processor included in the system.  AS used, the RAM becomes a write only RAM as far as the processor is concerned.  Anytime a clear text key appears on a bus connecting the RAM with an enciphering chip used in the system, an interface between the bus and the processor is used to uncouple the bus from the processor.  The system can also be used for "key encrypting key schemes".

Abstract: ABSTRACT  This invention is for improving the radiation hardness or radiation resistance of GaAs MESFETs.          According to this invention, an n-type active layer is formed by doping in the GaAs crystal.  The n-type active layer includes an upper layer and a heavy doped lower layer.  A Schottky gate electrode is provided on the active layer, so that the carrier concentration in the active layer and the thickness of the active layer are set required values.  According to this invention, not only in the case of a total dose of exposure radiation of R=1x109 roentgens but also in the case of a higher total dose, at least one of the threshold voltage Vth of the GaAs MESFET, the saturated drain current Idss there of, and the transconductance gm are in their tolerable range.  Consequently a semiconductor device comprising the GaAs MESFET and a signal processing circuit cooperatively combined therewith can operate normally as initially designed, with a result of conspicuously improved radiation hardness.

Moreover, the coating composition has applicability to a great variety of metal substrates. Such substrates include base metal such as steel as well as metal coated substrates such as zinc electroplated steel. Furthermore, the coating compositions can be useful when applied to substrates sensitive to elevated cure temperature, e.g., annealed steel. In one important aspect the composition can contain hexavalent-chromium-providing substance. Particulate metal may be present in the composition. A composition furthermore contains a special organic acid/alcohol reducing agent combination for the hexavalent chromium.      The composition can provide a low-cure coating on a metal substrate, which can then translate into higher production line speeds as when used for coating of metal coils.

Abstract: A combustion chamber for combusting a substance includes a burner and at least three successively disposed parts including a primary chamber, a secondary chamber and an ash discharge chamber. The burner is associated with and conducts a first air flow to the primary chamber. The primary chamber has an inlet for conducting a second air flow for substoichiometric combustion of a substance to be combusted at a temperature below an ash softening point and without clinker flow. The secondary chamber has an inlet for conducting a third air flow for brief, intensive, complete combustion of the substance discharged from the primary chamber with clinker flow, and the secondary chamber has walls and a material lining the walls being resistant to fluid clinker. A process for combusting a substance being at least partially formed of combustible material includes feeding an air flow to the substance for substoichiometrically combusting the substance at a temperature below an ash softening point without clinker flow but with formation of a residue, and subsequently admixing a further air flow with the residue of the substoichiometric combustion for completely combusting the residue and forming flue gas and flowing ash. Prepared pyrolysis residue and incompletely burned gas may be discharged from a pyrolysis reactor as the at least partially combustible material made by low-temperature carbonization of trash in a system for thermal trash disposal.

Abstract: A hitch control system includes a draft force sensor, a hitch position sensor, an operator command lever, an upper hitch position limit setter, a mix setter, a drop rate setter and a control unit which generates control signals as a function thereof.  The control system includes a first (load) control mode wherein the hitch is controlled as a linear function primarily of sensed draft force and a second control mode wherein the hitch is controlled purely as a non-linear function of sensed hitch position.  In the load control mode, a reference position value is used as a set point representing only the lower range of positions of the hitch.  Draft force sensitivity and system gain values are derived from the mix setter so that increasing the sensitivity also increases the system gain.  The sensitivity value is limited within a predetermined range.
