IPC: B01D65/10
Filed: 1992-12-05
Abstract: PURPOSE:To accurately grasp the interface electrostatic effect based on zeta potential on the basis of a liquid separation membrane when a liquid is subjected to separation treatment by micro-filtration by allowing an evaluation solution along the surface of the liquid separation membrane and measuring the potential difference between both ends of the membrane with respect to the flow of the evaluation soln. CONSTITUTION:A measuring cell composed of an insulator is constituted of a lower cell piece 1 having a groove 11 and an upper cell piece 2 having the protruding part 21 fitted in the groove 11 and the liquid inlet hole 22a and liquid outlet hole 22b provided to both sides of the protruding part 21 and the width of the protruding part 21 is made equal to that of the groove 11. Next, when a flat membrane 1 is evaluated, two flat membranes 1 are set to the measuring cell so that the surfaces (s) thereof are mutually opposed and packings (c) are held between both ends of the membranes and both side parts of the groove 11 and both side parts of the protruding part 21 are sealed by the packings (c) and chemically stable electrodes 3 are arranged to the liquid inlet and outlet holes 22a, 22b and, subsequently, an evaluation soln. is allowed to flow to measure the potential difference between the electrodes 3, 3. The zetapotential of the membrane can be calculated from this potential difference.

Title: Bridge of vertically integrated mixed rigid frame structure
Inventor: TAGUCHI TOSHIHIKO
IPC: E01D101/30
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To inexpensively and quickly perform an overhang erection even in a construction site where the constructing space is limited by providing a lower substructure having a concrete structure, and an upper substructure having a steel structure, and rigidly bonding the connecting part between the lower substructure and the upper substructure by a composite structure. SOLUTION: A lower substructure 2 is formed of a concrete structure since the vertical compression force is dominant. On the other hand, an upper substructure 3 is formed of a steel structure since it is extended in the bridge axial direction, and the bending moment is dominant. The bonding part 11 between the lower substructure 2 and the upper substructure 3 is rigidly bonded by a composite structure. Thus, erecting bars can be loaded on the upper substructure without using a timbering, and an economic and quick overhang erecting work can be performed even in a ground difficult to sufficiently ensure a field constructing yard.

Title: Multilevel writing method of nonvolatile semiconductor memory
Inventor: TOMIOKA YUGO
IPC: H01L27/115
Filed: 1992-12-07
Abstract: PURPOSE:To provide a multilevel writing method of a nonvolatile semiconductor memory by which the memory can be easily handled and a large quantity of data can be stored in a less number of memory cells. CONSTITUTION:The threshold voltage of each memory cell of a nonvolatile semiconductor memory can be easily set and the memory cells can easily store three or more kinds of data when a high voltage is applied across a control gate electrode and the voltage corresponding to input data is applied across a drain electrode. Therefore, the storage capacity of the semiconductor memory can be remarkably increased by using the same number of memory cells as in the conventional example. In addition, by using Fowler-Nordheim tunneling method for writing, the quantity of charges injected into a floating gate can be easily controlled as compared with the case where the hot-electron method is used.

Title: Detecting device for foreign object
Inventor: YAMAMOTO KENJI
IPC: G01V8/16
Filed: 1992-12-08
Abstract: PURPOSE:To prevent deterioration of detection sensitivity that could be caused by variation in the amount of light incident on a surface to be inspected and/or decrease in the gain of a light receiving system by providing between a light source and an illuminating optical system a monitor portion for detecting the amount of shift and angular deviation and a control portion for correcting them. CONSTITUTION:A laser beam from a light source 1 is split by the beam splitter 9a of a monitor portion M1 and part of the beam reaches a beam position detecting element 10a and the portion of the beam transmitted through the splitter 9a is further split by a beam splitter 9b and reaches a beam position detecting element 10b and the position of each split beam relative to the optical axis is detected. An arithmetic circuit 11 computes the amount DELTA of shift and angular deviation alpha relative to the reference optical axis of the laser beam according to the outputs of the elements 10a, 10b. A control portion C corrects the amount DELTA of shift by operating a motor- driven halving 12 using a drive portion 13 and corrects the angular deviation delta by controlling a polarizing prism 14 using a drive portion 15, so the shift and the angular deviation are eliminated before the beam impinges on the illuminating optical system, and the amount of illuminating light applied to a surface 6 to be inspected is not reduced and the detection sensitivity is maintained.

Title: Semiconductor memory device
Inventor: OSHIMA SHIGEO
IPC: G11C11/407
Filed: 1999-12-13
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor storage memory device which can reduce the pattern occupying areas of data registers by shortening random cycle time at writing time. SOLUTION: In the semiconductor storage memory device, the data registers 104-1 and 104-2 for latching written data are positioned closely to memory cells MC in a memory core section 100. Since data can be sent in advance to the upstream section of a data path for writing at the time of performing late writing operation, the random cycle time at writing time can be shortened by making the writing speed of data in a memory cell faster in the next write cycle. In addition, when a read command is inputted before the next write command is inputted and a consistency discriminating device detects address coincidence, the data latched in the data registers 104-1 and 104-2 are read out instead of the results of amplification by means of DQ read amplifiers 102-1 and 102-2, transferred to data lines RDe and RDo, and outputted to the outside.
