摘要： The present invention relates to a pneumatic servo valve, and more particularly, to a pneumatic servo valve, wherein displacement of a spool due to flow force of a fluid is prevented by firmly holding the spool just after position control for the spool is completed, thereby ensuring the stability of a valve system, and an encoder is employed as a spool position detecting means. The pneumatic servo valve comprises a hollow main body with a supply port, a discharge port and an exhaust port; a sleeve which is contained in a hollow portion of the main body and has slots communicating with the respective ports, and a chamber therein; a spool axially slidably installed within the chamber to control the flow of a fluid into the respective ports according to the position thereof; a torque motor installed at one side of the main body to control the position of the spool in response to electrical signals; and a spool position detecting means for compensating positional errors by receiving the fedback position of the spool. The pneumatic servo valve further comprises a spool holding means including a ball nut 60 which is engaged, via a ball, with a helical groove formed on a connection rod of the spool connected to the torque motor and rotates when the spool moves linearly, and an electronic brake for holding the ball nut not to rotate when the spool is stopped.

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.

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.
