    摘要： Provided is an optical transceiver for reducing crosstalk, comprising a light signal transmitter, a photoelectric transducer having a light transmitting device that converts the electrical signal into the light signal for transmission and a light receiving device that converts a received light signal into an electrical signal, and an electronic component that is located on a PCB connected to a leadframe or inside the optical transceiver module and amplifies, modulates, and demodulates the electrical signals in receiving and transmitting, whereby it is possible to implant the crosstalk level of less than −90 dB capable of retaining the reception sensitivity to −26 dBm in the optical transceiver, by forming the dummy ground lines on the substrate to reduce the crosstalk between the light transmitting device and the receiving device mounted on the silicon substrate.

    摘要： The present invention relates to a recombinant Escherichia coli having phbCAB originated from Alcaligenes eutrophus and an overproduction method of polyhydroxyalkanoate using the same, more precisely, a recombinant Escherichia coli ‘MG1655/pTZ18U-PHB’ or ‘JIL938/pTZ18U-PHB’ having phbCAB originated from Alcaligenes eutrophus and an overproduction method of polyhydroxyalkanoate comprising the steps of preparing transformed Escherichia coli having phbCAB originated from Alcaligenes eutrophus, inoculating and culturing the cells (growth phase), inducing the production of polyhydroxyalkanoate in the recomibnant Escherichia coli (stationary phase and producing phase), and inducing the extracellular secretion of the polyhydroxyalkanoate from the recombinant Escherichia coli. The method of the present invention facilitates not only overproduction of polyhydroxyalkanoate such as polyhydroxybutyrate by a simple batch culture but also industrial use of biodegradable polyhydroxyalkanoate replacing conventional non-biodegradable plastics by its simple and easy fermentation, separation and purification process.

    摘要： A variable speed motor is disclosed. The variable speed motor includes: a main winding including first and second main windings, and an auxiliary winding including first and second auxiliary windings, wherein the main winding and the auxiliary winding are wound on a stator to form a plurality of poles; and a plurality of relays for performing a switching operation between serial/parallel connections of the first and second main windings or the first and second auxiliary windings. The variable speed motor includes: a stator on which a 4-pole winding and a 12-pole winding are wound; a plurality of tap windings connected in series to a 4-pole main winding forming 4 poles, for extending a variable range of rotation speed of the motor during a 4-pole operation mode; and a phase control circuit for varying rotation speed of the motor by controlling a phase of an input power-supply signal during a 12-pole operation mode. Therefore, the variable speed motor greatly extends the range of a variable speed of the motor, and does not require an additional drive unit for varying the motor speed, such that production costs are greatly reduced, and electromagnetic vibration noise caused by a low-speed control mode of the motor is also greatly reduced. Rotation speed of the motor is controlled by a phase control operation and a winding switching operation, such that the variable speed motor effectively controls the motor speed, and greatly reduces power consumption.
