Title: Optical loss measuring system, optical fiber coupler and method for measuring optical loss
Inventor: SCHMIDT SIEGMAR
IPC: G01M11/00
Filed: 1999-07-08
Abstract: PROBLEM TO BE SOLVED: To calibrate and measure an accurate loss regarding an optical component by coupling a reference cable having a predetermined reflectivity to a first output of an optical fiber coupler, measuring a power of a reflected light, replacing the cable with a client's cable applicable to a unit to be measured, and measuring a value of a reflected light power. SOLUTION: The optical fiber coupler 40A comprises a coupler 150 coupled at one end to a coupler 160 in such a manner that the couplers 150, 160 have severe directivities. An optical power Ps from a signal source is inputted to an input 170 of the coupler 150, divided at a part coupled to an output 180, and at the other coupled to the coupler 160. The coupler 160 is further partly coupled to an output 190, and the signal outputted to the output 190 is partly coupled to an output 200 of the coupler 160. An optical power meter 210 coupled to the output 180 measures an optical power M substantially corresponding to the power Ps at the input 170, and an optical power meter 220 coupled to the output 200 measures a reflected light power P.

Title: Production of powdery gel
Inventor: SUGURO YOSHIO
IPC: C01B33/16
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of fine powder and to inexpensively obtain a powdery gel at a good yield by adjusting the liquid content to the total weight of the lumpy gel obtd. by a sol-gel method to a specific range at the time of pulverizing the lump gel by a pulverizing machine. SOLUTION: A metal alkoxide (e.g.: tetramethoxysilane) is produced by the sol-gel method and is hydrolyzed and gelatinized to produce the lumpy gel. The lumpy gel having the liquid content of 68 to 73wt.% is produced by adjusting the consumption of the water used at the time of the hydrolysis, the temp. at the time of gelatinization, etc. On the other hand, the pulverizing machine which is fixed with the inverted cone-shaped screen 3 having openings in a perpendicular direction and has the impeller 2 capable of imparting rotational driving force along the shape of the screen 3 within the screen is prepd. The lumpy gel is charged into the pulverizing machine and the lumpy gel is ground by rotation of the impeller 2.  The pulverized gel is further pressed onto the screen 3 by the centrifugal force of the impeller 2 and is passed through the holes of the screen 3, by which the powdery gel is obtd.

Abstract: PURPOSE:To reliably open a bag having a folded part at the bottom and avoid the inability in identifying whether a bag can be opened even if a machine speed varies by opening in two stages a pair of suction disks sucked to both faces of a lower part of the bag for expanding the bag. CONSTITUTION:Films on both upper faces and lower upper faces of a bag 1 having a folded part interposed by a fastener 2 are sucked by respective pairs of suction disks 3, 4, a lever 5 is inserted into the bag 1 while the suction disks are retreated, and air is blown for expanding the bag 1.

Title: Production of beta-manganese dioxide
Inventor: KAMIHIRA AKIRA
IPC: H01M4/50
Filed: 1983-10-18
Abstract: PURPOSE:To produce beta-MnO2 having extremely high purity, by adding nitric acid to the product obtained by the thermal decomposition of manganese nitrate, and again carrying out the thermal decomposition if necessary twice or more. CONSTITUTION:Easily available manganese nitrate hexahydrate is subjected to the thermal decomposition at about 170-500 deg.C. If the thermal decomposition temperature is lower than about 170 deg.C, the degree of decomposition is insufficient, and when it is about >=500 deg.C, Mn2O3 may be produced as an impurity. The product obtained by the above thermal decomposition is added with preferably about >=0.52g-equivalent of nitric acid, and again subjected to the thermal decomposition by heating preferably at about 170-500 deg.C. High purity beta- MnO2 free from the impurities such as Mn2O3 can be produced by this process. The purity of the obtained beta-MnO2 can be further improved by repeating the second thermal decomposition two or more times.
