Title: Manufacture of enclosed nickel-cadmium battery
Inventor: IWAI KATSUJI
IPC: H01M50/186
Filed: 1982-07-21
Abstract: PURPOSE:To obtain an enclosed nickel-cadmium battery having an improved liquid leakage resistance by attaching a negative case to a packing coated with a sealing agent, then supplying an organic solvent in which the sealing agent is dissolved into the space formed between the packing and the negative case, being followed by pressing so as to cause the negative case, the sealing agent and the packing to be tightly unified. CONSTITUTION:An alkali-proof sealing agent which is soluble in an organic solvent, such as pitch, is applied to the surface of a packing to form a film 9 of the sealing agent. Next, a negative case 2 is attached to the packing 3, and an organic solvent such as toluene containing 5-50wt% of the sealing agent is supplied to a space 10 formed between the negative case 2 and the packing 3. After the space 10 is completely filled with the organic solvent, the negative case 2 is pressed so as to cause the negative case 2, the sealing agent 9 and the packing 3 to be tightly unified. Next, heating treatment is performed so as to remove the organic solvent. Although the sealing agent is forced out at a position 11 on the side of the negative case 2, this does not become a particular problem. By the means mentioned above, spaces due to the concaves and convexes of the negative case 2 are filled with the sealing agent 9, and the liquid leakage resistance of the battery is enhanced.

Title: Method for preventing electrolytic corrosion of magnesium alloy member
Inventor: OGIWARA YASUHITO
IPC: C23F13/00
Filed: 1980-09-16
Abstract: PURPOSE: To effectively prevent stray current corrosion of a clamped part of a Mg alloy member and a Zn plated washer and a periphery thereof by clamping said Mg alloy member and said washer by interposing a washer comprising an insulative material therebetween.  
     CONSTITUTION: Between a Zn plated washer 2 and a Mg alloy material, an insulation washer 3 of which a diameter is larger than that of the washer 2 and a thickness of 2mm or more made of ceramics or the like is interposed and said member 4 is clamped to the washer 2 by a bolt 1. As the result, if electrolyte 5 is accumulated to an outer part of the washer in said clamped part, because an end part of the washer 2 and a surface of the member 4 are sufficiently parted mutually, stray current corrosion of the member 4 is hardly generated.

Title: Method for determining failed section of aerial transmission line
Inventor: KANO HITOSHI
IPC: G01R31/08
Filed: 1988-05-27
Abstract: PURPOSE:To make it possible to determine a failed section in high accuracy even for complicated lines whose fault is hard to find, by using a plurality of functions that indicate the maximum values in the failed section, and performing overall judgment. CONSTITUTION:Current sensors 4 transduce the instantaneous values of a current flowing through an overhead ground wire 1 into corresponding intensities of light. Multiplexing transmission devices 5 perform light/electricity transducing and coding of the outputs of the sensors and add the results on a signal from the upstream in a multiplex pattern. Then, electricity/light transducing is performed, and the result is transmitted to the downstream. A light receiving circuit 6 performs light/electricity transducing of the optical output of the device 5 at the final point of the downdstream. The multiplexed signal is decomposed. The current value and the current phase are obtained for every sensor. In a fault-evaluating-function operating circuit 7, two functions fn and fn' are computed for every section. In this functions, the following factors are used for each section: current value; phase difference; average current value; the maximum current value in all sections; and the maximum current value at the time of no fault. The section wherein these functions have the maximum values is determined to be the failed section. When the two functions are used in this way, erroneous determination is not performed regardless of the form of the fault because one function supplements the maximum value even if the other function does not have the maximum value at the point of the fault.

Filed: 1992-05-21
Abstract: PURPOSE:To prevent the decrease of population inversion of EDF and stably keep a noise figure low when the range of amplification gain of signal light is wide, by arranging an optical attenuation means on the output end side of an optical fiber. CONSTITUTION:Pumping light from a pumping light source 24 enters an Er- doped fiber 22 via a coupler 26 and an isolator 28 and excites Er to amplify signal light input. The amplified signal light is attenuated by an optical moss fiber 30, and then outputted to the outside after passing an optical isolator 32, a bandpass filter 34 and a splitter 36. A part of the amplified signal light is branched by the splitter 36 and fed back to a driving power source 42 of the pumping light source 24 via a control circuit 40, according to the monitor output of an optical detector 38. Hence the power of signal light output is kept constant. Since a high loss fiber 30 is connected with the output end of the Er-doped fiber 22, the amplification gain of the Er-doped fiber 22 part can be kept high by previously setting the pumping output high.
