摘要:
Disclosed is a copolyester resin composed mainly of terephthalic acid, ethyleneglycol, 1,4-cyclohexanedimethanol, polyethyleneglycol bisphenol-A and a multifunctional monomer. According to the current invention, the multifunctional monomer and polyethyleneglycol bisphenol-A are additionally copolymerized along with 1,4-cyclohexanedimethanol, whereby the resultant copolyester resin can have low haze and high melt viscosity and melt strength, with superior moldability due to low melt pressure. In addition, extrusion blow molded articles and profile extruded articles, such as bottles and tubes, are provided by use of the copolyester resin having superior properties.

An apparatus and method for controlling a linear compressor with an inverter unit. In the apparatus and method, a capacitor is connected between a driving motor and an inverter unit that applies a voltage to the driving motor according to an output frequency thereof, thereby preventing a jump phenomenon due to an inductance of the motor coil. Furthermore, the linear compressor is precisely controlled through the inverter unit, thereby enhancing stability of the apparatus.

An apparatus for effectively filtering and separating fine floc, algae, suspended solids, etc. remaining in water after biological and physiochemical treatment is provided. The fine filtering apparatus includes flexible fibers that control packing density, thus improving filtration efficiency, the amount of clarified water, and filtering duration, and reducing power consumption compared to a conventional filtering apparatus is provided. In the filtering apparatus, flexible fibers having an effective diameter of 1 to 60 μm and which are flexible, elastic, and have proper surface roughness extend in the longitudinal direction of the apparatus. A jacket shaped unit for supplying source water (supplied water) has a porous structure. Clarified water (treated water) is discharged through a central porous chamber. The whole filter media layer can be utilized as a particle-entrapping space.
摘要:
A method and apparatus for executing a single beat write (SBW) store instruction during a cache store linefill operation are disclosed. In accordance with the present disclosure, an address associated with the cache memory store linefill operation is first received. This address comprises a tag portion and an index portion. For the cache store linefill operation, the tag portion of this address is sent to a tag latch while the index portion is sent to a burst index latch. During the cache store linefill operation, a second address associated with the single beat write store instruction is received. This second address also comprises a tag portion and an index portion. In response to a determination that a critical word of the cache memory store linefill has been received, the tag portion of the second address is sent to the tag latch and the index portion of the second address is sent to an SBW index latch. By doing so, the single beat write store instruction may be executed before the completion of the cache store linefill operation.

摘要:
Provided are a coated steel sheet, a hot press formed product using the steel sheet, and a producing method thereof. Conditions for hot-dip coating bath are optimized when an aluminum-coated steel sheet is produced using a hot rolled steel sheet or a cold rolled steel sheet, and processes are controlled during production of a hot press formed product from the steel sheet, thereby forming a coating layer having a high ratio of (Fe3Al+FeAl) compound layer on the surface of the steel sheet. In cases where the (Fe3Al+FeAl) compound layer has an appropriate occupancy ratio with respect to the whole thickness of the coating layer, good resistance against crack and corrosion can be achieved to improve a local corrosion resistance of the hot press formed product, particularly, a pitting corrosion resistance. Therefore, high-quality hot press formed products can be produced with high productivity and lower costs.
