Patent CA-2701180-A1 (CA)
Inventor: OH HAKJUNE
IPC: G11C11/4193
Filed: 2008-09-15
Abstract: A non-volatile semiconductor memory device, which comprises (i) an interface having an input for receiving an input clock and a set of data lines for receiving commands issued by a controller including an erase command; (ii) a module having circuit components in a feedback loop configuration and being driven by a reference clock; (iii) a clock control circuit capable of controllably switching between a first state in which the reference clock tracks the input clock and a second state in which the reference clock is decoupled from the input clock; and (iv) a command processing unit configured to recognize the commands and to cause the clock control circuit to switch from the first state to the second state in response to recognizing the erase command. The module consumes less power when the reference clock is decoupled from the input clock than when the reference clock tracks the input clock.

Abstract: The invention is intended to exploit the force of the wind to generate a torque to be used for various purposes, among which, the production, via a mechanical coupling with alternators, of electric energy. The novelty lies in the new arrangement of the blades and of the eolian generator which makes it universally installable on the roof of any building owing to the very low visual and architectonic impact and its structural versatility. Its particular architecture makes it possible to fully exploit the roof effect and wall effect, these being phenomena that, by generating a rise in the wind' s speed, allow the generator to have a production capacity exceeding the one of systems having equal dimensions.

Abstract: The invention provides improved energy content in and shaft power recovery from off-gas from xylene oxidation reactions while at the same time minimizing wastewater treatment cost. More shaft power is produced using off-gas than is re-quired to drive the main air compressor, even with preferred, relatively low oxidation temperatures. Simultaneously, an amount of wastewater greater than byproduct water from oxidation of xylene is kept in vapor form and treated along with off-gas pollutants in a self-sustaining (self-fueling) gas-phase thermal oxidative destruction unit. Optionally, off-gas is combined from multiple xy-lene oxidation reactors, comprising primary and/or secondary oxidation reactors and forming TPA and/or IPA. Optionally, air compressor condensate and caustic scrubber blowdown are used in a TPA process or as utility water, effectively eliminating nor-mal flow of liquid wastewater effluent from a TPA plant. Optionally, PET off-gas containing the water of PET formation is treated in a shared thermal oxidative destruction unit, effectively eliminating normal flow of liquid wastewater effluent from a combined pX-to-TPA-to-PET plant.
