A composite polyamide reverse osmosis membrane and method of producing same. In a preferred embodiment, the membrane is made by coating a porous polysulfone support with an aqueous solution containing 2 wt % m-phenylenediamine (MPD), and 0.1 wt % di(ethylene glycol) hexyl methyl ether. Next, the excess solution is removed, and the coated support is dipped in 0.1 wt % organic solvent solution of trimesoyl chloride (TMC) in a mixture of alkanes having from 8 to 12 carbon atoms. After draining the TMC solution off, the resulting composite membrane is air dried and then rinsed in a basic aqueous solution. The resultant membrane exhibits a flux of 21.3 gfd and a salt rejection of 98.9% when used at 225 psi for an aqueous solution containing 2000 ppm of NaCl.

Disclosed herein are a building management system (BMS) and an operating method thereof. A BMS controller of a LonWorks network integrally controls a multi-air conditioner system which uses a different communication scheme, without modification of the structure thereof. The building management system comprises a BMS controller (50) for centrally controlling subsystems (60 and 70) installed in the building and connected to a LonWorks network (N2), an air conditioner system (70) including a plurality of outdoor units (71) and a plurality of indoor units (72) connected to the outdoor units, and a Lon gateway (80) for converting data of an air conditioner system network (N1) into data of the LonWorks network (N2), and vice versa, to enable the BMS controller (50) to centrally control the air conditioner system (70). The building management system can incorporate a multi-air conditioner system which utilizes a different communication technology, without modification. The building management system also facilitates low-cost installation of an integrated control system in the building because each one of the indoor units constituting the multi-air conditioner system can be separately controlled without the need for a communication module to be connected to each indoor unit.

Delay locked loop circuitry for generating a predetermined phase relationship between a pair of clocks. A first delay-locked loop includes a delay elements arranged in a chain, the chain receiving an input clock and generating, from each delay element, a set of phase vectors, each shifted a unit delay from the adjacent vector. The first delay-locked loop adjusts the unit delays in the delay chain using a delay adjustment signal so that the phase vectors span a predetermined phase shift of the input clock. A second delay-locked loop selects, from the first delay-locked loop, a pair of phase vectors which brackets the phase of an input clock. A phase interpolator receives the selected pair of vectors and generates an output clock and a delayed output clock, the amount of the delay being controlled by the delay adjustment signal of the first delay-locked loop circuitry. A phase detector compares the delayed output clock with the input clock and adjusts the phase interpolator, based on the phase comparison, so that the phase of the delayed output clock is in phase with the input clock. As a result, there is a predetermined phase relationship between the output clock and the input clock, the phase relationship being the amount of delay between the output clock and the delayed output clock. Different phase relationships between the input and output clock are possible depending on the number of unit delays used in the path of the, delayed output clock or the output clock.
