摘要： It is an object of the present invention to provide a membrane separation apparatus and a membrane separation process that are unlikely to cause membrane fouling and plugging, capable of achieving membrane separation even with relatively low flow rate of water, have an excellent membrane packing density, and are unlikely to cause deposition of foreign components in the apparatus. In order to achieve the above object, according to the present invention, vessel-type inner casings are disposed in a pressure vessel along the longitudinal axis thereof, in which the pressure vessel has a water inlet at a first end and a concentrate outlet at a second end. A flow-regulating plate is disposed on the side of the water inlet of the pressure vessel. Stacks of membrane separation units are respectively disposed in the inner casings, and spacers are disposed between the adjacent membrane separation elements. The spacers also serve as sealing members. Each stack of the membrane separation units and the spacers together define a through-hole extending from a first side to a second side, of the stack of the membrane separation elements. The inner casings have permeate discharge passages along the longitudinal axis thereof. The permeate discharge passages are communicated with the through-hole of each stack of the membrane separation elements. Water that has been fed into the pressure vessel via the flow-regulating plate permeates through the membrane separation elements and is discharged to the outside via the through-holes and the permeate discharge passages.

摘要： There is provided an error rate select circuit activated in an information sustaining mode, wherein data is read out from a memory circuit comprising dynamic memory cells and inspection bits for detection and correction of an error. If no error is detected, a first detection signal is accumulated in a first direction, that is, the first detection signal is added to a sum. If an error is detected, a second detection signal is accumulated in a second direction, that is, the second direction signal is multiplied by a weight to produce a product before subtracting the product from the sum. If the sum increases in the first direction, exceeding a predetermined value, the refresh period is lengthened by a predetermined incremental time. If the sum decreases in the second direction, becoming smaller than another predetermined value, the refresh period is shortened by a predetermined decremental time.

摘要： An ATM switching system comprises a switch unit including a plurality of input ports and a plurality of output ports having the same cell transmission rate, and a multiplexer for multiplexing cell trains outputted from at least two output ports into a single cell train and outputting the cell train to a high-speed output line (and/or a demultiplexer for demultiplexing a cell train from an output port into a plurality of cell trains and outputting the cell trains to a plurality of low-speed output lines). The switch unit includes a buffer memory for temporarily storing cells inputted from the input ports while forming a queue chain for each output line to which each cell is to be outputted, a demultiplexer for distributing the cells read from the buffer memory among the output ports in circulation, and a buffer memory control circuit for controlling the write and read operation of cells with the shared buffer memory. The buffer memory control circuit has a control table device for outputting an identifier of an output line to which the cells read from the shared buffer memory are to be outputted, and cells are read from the chain designated by the output line identifier outputted from the control table device.

摘要： The invention relates to a high-density DRAM fabrication technique for forming a source/drain contact between word lines in a self-alignment manner, with the offset length between a source region and a drain region of a peripheral transistor maintained at an adequate value. After gate electrodes (i.e. word lines) are formed, a first insulating layer, which is thin enough not to block up space defined between the word lines, is deposited. The source/drain contact is etched as deep as the first insulating layer is thick to form an extraction electrode made of polycrystalline silicon. A second insulating layer is deposited until a spacer thickness (i.e. the sum of the film thickness of the second insulating layer and the film thickness of the first insulating layer) for determining the offset length is obtained. The first and second insulating layers are etched back for a distance corresponding to the sum of the film thickness of the second insulating layer and the film thickness of the first insulating layer so that a spacer (i.e. the residue of the insulating layers) is left on the side walls of the gate electrode. An implantation of highlevel impurities is performed to form heavily doped source and drain regions of a peripheral transistor. In-cell self-align contact is made possible while maintaining the offset length of the heavily doped source and drain regions

摘要： The present invention is aimed at providing a magnetic disk and a magnetic disk apparatus both of which have a high performance lubricating film which makes continuous sliding endurance and low adhesiveness compatible, and a lubricating film having a self repairing function which makes it possible to recombine scratched off lubricating agent from the magnetic disk surface by sliding with a head onto the magnetic disk surface. The lubricating film comprises at least two kinds of lubricating agents each of which forms an individual layer, the layers being laminated. An adhesion enhancing layer is formed between a magnetic film and a lubricating agent at the surface of the magnetic disk, and the adhesion enhancing layer is fixed onto the magnetic film surface. Then, the adhesion enhancing layer and the lubricating agent are combined. The adhesion enhancing layer and the lubricating agent form a salt or complex body, and the lubricating agent can repeat adsorption and desorption with the adhesion enhancing layer reversely by a thermal reaction.
