An L-threonine-producing Escherichia coli strain and a method for producing the same are provided. The Escherchia coli strain contains chromosomal DNA with inactivated metJ gene. Therefore, expression repression of threonine biosynthesis genes by a metJ gene product is prevented, thereby producing a high concentration of threonine. Further, a high concentration of L-threonine can be produced in high yield using the method.

The present invention relates to a cathode for use in a field emission device. In a triode-type cathode for use in an electron emission device being a core component constituting a field emission device, the present invention includes forming a catalytic layer at the sidewall of a gate hole and then growing an emitter in the catalytic layer, thus uniformly distributing an electric field generated by a voltage applied to a gate electrode over the emitter. Therefore, the present invention can improve the brightness contrast at a low anode voltage and also can control electrons emitted from the emitter only with the gate voltage.

A field emission display having an n-channel high voltage thin film transistor is disclosed. According to the present invention, a signal for driving pixels controls by the nHVTFT attached with each pixel, therefore, the signal voltage of row and column drivers is exceedingly decreased. As a result, it is possible to implement a field emission display capable of providing a high quality picture in a low consumption power, a low driving voltage and inexpensive to manufacture, and preventing a line cross talk using the nHVTFT. By using a cylindrical resistive body underlying a cone-shaped emitter tip, the present invention is to provide a field emission display having an excellent contollability and stability of the emission current, and a dynamic driving capability.

摘要:
Remote card content management using synchronous server-side scripting is provided. A system includes a computer processor and a script interpreter executable by the computer processor. The script interpreter is configured to perform a method. The method includes parsing a script configured to perform a card content management operation as a sequence of operations for a secure element based on receiving a request from a mobile device located remotely from the computer processor. The method also includes creating an execution context for the script to identify the sequence of operations in the script as non-flushing and flushing nodes. A flushing node is identified as an operation that sends a response to the request and expects a subsequent request from the mobile device for the secure element. The method further includes pausing execution of the script upon sending the response at the flushing node.
