Patent KR-20010092783-A (KR)
IPC: B01D65/08
Filed: 2000-11-15
Abstract: A filtering element has ultrafiltration or microfiltration hollow fiber membranes extending horizontally between a pair of opposed horizontally spaced, vertically extending headers. Side plates extending between the pair of vertically extending headers define a vertical flow channel through the element. Modules are created by placing the elements in place without obstructing the vertical flow channels. Each element may be released from the frame, however, and removed by sliding it in a direction substantially normal to its headers without disassembling the remainder of the module. The elements have associated releasable water tight fittings between the elements and a permeate collector, the releasable water tight fittings being releasable by removing an element from the frame. An aerator below the module has a plurality of air holes located to provide a line of air holes below each element or below a side plate between each pair of elements. In a preferred process, permeate flux is less than 50 L/m<2>/h and preferably less than 35 L/m<2>/h, aeration to scrub the membranes is provided during periods of time when permeation is periodically stopped and accumulated solids are removed by periodically emptying and refilling a tank containing the elements. A bubble point test is applied to each row of the module in turn, the presence of bubbles in a particular flow channel indicating which, if any, elements of a row are suitable.

Abstract: PURPOSE: To provide a hydraulic pressure control unit of an automatic transmission which can dissolve a problem that causes a delay in a supply of working fluid to frictional elements as the frictional elements are brought into a high revolution condition. CONSTITUTION: According to this invention, a large standby pressure Ps(Nt) is supplied to a low clutch L/C and the filling up of the working fluid to the clutch L/C finishes quickly by commanding the standby pressure Ps(o) as the hydraulic pressure Ps(Nt) which increases as much as a hydraulic pressure correction ΔP as shown in a solid line corresponding to increase of the number of turbine revolution Nt between the time t1 of finishing the control precharge pressure Pr and the torque phase starting time 2, so a time difference between the commanding pressure PI of the torque phase starting time t2 and an actually supplied clutch supply pressure Pc can be reduced. So, according to this invention, the delay in supply of the clutch supply pressure Pc to the clutch L/C can be solved as the low clutch L/C is brought in high revolution condition. Additionally, a surge pressure ΔP at the torque phase starting time t2 can be reduced as shown in the area Γ according to that invention, so the shock caused by this surge pressure ΔP can be softened.

Abstract: PURPOSE: A method for detecting a physical channel transmission format is provided to detect a transmission format exactly by differently granting the weight value of a correlation value according to the bias level of the correlation value in order to detect the transmission format of a received signal. CONSTITUTION: As a PDCCH(Packet Data Control CHannel) is transmitted at one of slot mode 1, slot mode 2 and slot mode 4, a receiving block executes decoding for every mode. In case that a decoding result is not satisfactory, the receiving block applies a regeneration method using a regeneration block.

Abstract: PURPOSE: To obtain an exposure mask, a method for manufacturing the mask and a method for forming a pattern so that a cell can be finished to its most end part in a desired dimension without using a dummy pattern, therefore, without increasing the cell area. CONSTITUTION: The end part of the memory cell is subjected to optical proximity correction/process proximity correction(PPC) so as to decrease the dimensional difference in the finished pattern in the end region of the memory cell. By subjecting the end part of the memory cell to the PPC, the cell can be finished to the most end part of the cell into a desired dimension without increasing the cell area. Since the mask dimension of the end part of the cell can be determined by the PPC, the designer is not required to change the design of the cell end even when the conditions for the lithographic process are changed. That is, the optimum mask dimension of the cell end can be obtained only by changing the rule of the PPC according to the changes in the lithographic process, and this results in the decrease in the load relating to designing.
