Title: Permselective hollow yarn composite membrane and production thereof
Inventor: NITTA KAZUHIDE
IPC: D01F8/12
Filed: 1987-07-13
Abstract: PURPOSE:To obtain a hollow yarn composite membrane which is high in both degree of desalting and amount of water permeation with a simple method by using copolyamide consisting of specified constitutional units and dissolving it into a solvent in which aromatic polysulfone is not dissolved and applying this soln. on a porous supporting material consisting of a aromatic polysulfone. CONSTITUTION:Copolyamide which mainly includes the constitutional units shown in the general formulas 1, 2 in molar ratios of 95/5-35/65 is synthesized by allowing diamine component such as diaminodiphenylsulfone and aminobenzoic acid to react with aromatic dicarboxylic acid halide such as isophthalic acid chloride. A coating agent is obtained by dissolving it into a solvent which is a non-solvent for a supporting material e.g. into methyl cellosolve. After immersing a porous hollow yarn supporting material consisting of aromatic polysulfone into the coating agent, it is dried to remove the solvent and a permselective hollow yarn composite membrane wherein the surface of the supporting material is coated with copolyamide in thickness not more than 10mum is obtained.

Inventor: ONISHI MASARU
IPC: H04B10/07
Filed: 1989-07-06
Abstract: PURPOSE:To correctly detect the disconnection of an optical signal input by monitoring a change in a control signal for controlling a phase difference in a phase synchronizing loop circuit and detecting the disconnection of the optical signal input. CONSTITUTION:When an optical signal input is disconnected, the contents of an output from a clock extraction circuit 3 are made completely indistinct and the indistinct contents are inputted to a phase synchronizing loop circuit 2, so that a phase difference control signal is changed to a voltage shifted from a fixed voltage obtained when the optical input exists. The DC phase difference control signal is compared with a previously set reference value by an optical input disconnection deciding circuit 4 to decide the disconnection of the optical signal input. Thus, the disconnection of the optical signal input can correctly be detected.

In performing the filling operation, moisture is produced on the surface of the fine ice 16 to permeate into the powder 17 and form a moisture absorption layer. Thereby, air-permeable gap parts 19 are formed in the fine ice laminated body 9. When the cup body 2 is transferred to a refrigerator cabinet, the moisture absorption layer is frozen to form a frozen layer 24 and keep the powdery drink in the dried state. In drinking, the lid body 13 is removed to pour water at ordinary temperature, and the contents in the cup body 2 are mixed by stirring with a spoon, etc.

Abstract: PURPOSE:To reduce interference between patterns lower than that in a dictionary and to realize pattern recognition with a few recognition error and with superior recognitionability by performing the learning of a recognition dictionary by using an equation on which a recognition error minimizing item is attached in a pattern recognizing system by a dynamic associated storage model.

Bidirectional remembrance between input and output is performed, and also, coupling weight is calculated and corrected. The correc tion of the bidirectional remembrance and the coupling weight are repeated while the recognition error is set at a value larger than (epsilon). When the recognition error goes to the value smaller than (epsilon), the next pattern is inputted, and the similar learning processing is performed. After the learning of (k) input patterns for learning are fin ished, the test of recognition is performed, and when the recognition error exists, the value of the constant (beta) of the learning is decreased, then, the similar processing is performed again and it is repeated until the constant (beta) goes to a sufficient low value. Thereby, it is possible to reduce the interference between the patterns than that in a storage dictionary by a conventional correlation matrix, and to perform the pattern recognition with superior identifiability.

Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To provide cutout lines of a piece after punching with a finish as fine as surface by coating guard layer composed of resin film, etc., on the print face reverse to the punching direction. SOLUTION: On both faces of a base plate 1 made of a thick paper is printed with a design or picture to form print layers 2, 3, and further, a guard layer 4 is either coated or laminated on the print layer 3 reverse to the punching direction of a punch C. Thickness of the film guard layer 4 is specified, for example to 15-50μm. For the guard layer 4 to be made of synthetic resin material, polypropylene or vinyl chloride is used in view of cost and coating work operability. When cut out by the punch C, the print layer 3 as the reverse face is pushed toward the punching direction while the cut out part of the base plate 1 and print layer 3 are kept guarded by the guard layer 4. The cut out lines are therefore finished fine as the cut edges would not project out toward the reverse face.

IPC: H05G1/70
Filed: 1984-08-24
Abstract: PURPOSE:To prevent any photographic error of two sides of a subject section for its two sides by transmitting X-ray fluoroscopic condition data concerning one of the sides to an X-ray controller installed on the other side. CONSTITUTION:A subject section 1 is examined by fluoroscopy from the FL side by means of devices 12-14 and 5. Optimum fluoroscopic tube voltage and current (FKV) and (FmA) are produced by an automatic luminance controller according to the state of the subject section 1. The X-ray controller 14 has a mechanism for automatically obtaining optimum photographic condition for the section 1 according to FKV and FmA. Therefore, photographic condition is automatically set in the X-ray controller 14 when fluoroscopic condition is determined. Following that, the fluoroscopic condition of the FL side is transmitted to the LA side of the subject section 1 through X-ray controllers 14 and 4 by means of a transmitter, thereby automatically setting photographic condition for the LA direction. Accordingly, it is possible to prevent any photographic error for the FL and the LA sides of the subject section 1.
