摘要: Cascode voltage switch (CVS) logic circuits include a CMOS logic tree having multiple logic branches and a bipolar, branch isolation transistor. Each logic branch of the logic tree changes state between a logic "1" and a logic "0", with a state change being manifested as a charging or discharging of the logic branch. The bipolar transistor comprises a multiple-emitter bipolar transistor wherein each emitter is electrically coupled to a different logic branch of the CMOS logic tree. A precharge circuit, coupled to the logic tree via the bipolar transistor, provides charge to an output of the CVS circuit prior to operation of said logic tree. The logic branches of the logic tree are charged and discharged substantially independently of one another thereby enhancing speed of the combinatorial logic circuit. Various circuit modifications and generalizations are also discussed.

摘要: An apparatus and method for testing an access time of a macro embedded in a LSI chip. The apparatus includes a logical gate connected to the output latches of the macro, thereby controlling the access time of the macro, and a test latch for determining an on-chip delay time between a test signal for enabling the output latches and an input signal for enabling the macro. The method includes the steps of determining the on-chip delay time between the test signal and the input signal, thereby allowing the test signal to be synchronized with the input signal, supplying the synchronized test signal to the output latches for a manufacturer specified macro access time, and testing the latched output data from the macro.

摘要: A solid-state chlorine dioxide generator for generating an aqueous solution of ClO2 is formed within a block comprising an eductor for establishing a vacuum pressure and a reaction column for producing ClO2 from precursor chemicals. The eductor has a water stream flowing therethrough which establishes a vacuum pressure and draws the ClO2 from the reaction column into the water stream to form an aqueous ClO2 solution. The reaction chamber comprises a novel transition zone of increasing flow area wherein the precursor chemicals thoroughly mix resulting in conversion efficiencies of precursors into ClO2 of 95% and above.

摘要: A methodology is provided for reducing an arbitrary Boolean logic expression to static CMOS circuits by the use of a general matrix of P channel devices and N channel devices which are interconnected in accordance with the terms of Boolean logic expressions derived from a truth table. More specifically, from a Boolean expression a sum-of-products expression giving the 1 binary data outputs of a truth table having a 0 input is found. This is accomplished by complementing, or barring, the literals which are a binary 1 when the output is 1 and leaving true or unbarred the literals that are a binary 0. Then each input of a given product term is applied to the control gate of a P channel device, which devices are connected in series with one end tied to a source of potential and the other end of the series circuit connected to an output terminal. Each product term is arranged in parallel with other P channel device series circuits to form one half of a complete logic matrix. Similarly, for the other half of the matrix, a sum-of-products expression giving the binary 0 outputs of a truth table having a binary 1 for an input is found. Each input of a given product term is applied to the control gate of an N channel device, which devices are connected in series with one end tied to a potential reference point, such as ground, and the other end of the series circuit is connected to the output terminal. Each product term is arranged in parallel with other N channel device series circuits.

摘要: An air-blow valve configured for clean-in-place capability is provided. The valve comprises a valve body defining a valve seat and internal fluid passageways. The valve further comprises valve components disposed within the valve body, including a plug, a piston, and a spring. The valve is separately operatively connected to a pressurized-air source and to a sanitizing-fluid source. In operation, the spring biases the piston, causing the plug to engage the seat, to prevent undesired fluid flow between the passageways and the connecting conduits. Alternatively, the spring biases the piston, causing the plug to disengage the seat, allowing fluid flow between the passageways and connecting conduits. Pressurized air is used to space the plug from the seat to achieve flow whenever desired, or alternatively to engage the seat to prevent fluid flow when desired. Periodic selective movement of the piston to space the plug from the seat, enables the cleaning solution to pass through the body and clean the internal passageways, the seat, and the plug, thereby rendering unnecessary disassembly of the valve and/or removal of the valve from the connecting conduits during valve cleaning.
