Title: Sealed lead-acid battery
Inventor: OMAE TAKAO
IPC: H01M2/38
Filed: 1992-10-23
Abstract: PURPOSE:To prevent stratification of an electrolyte so as to enhance the capacity and lifetime of a sealed lead-acid battery by housing, inside the battery, an electrolyte atomizer to be operated according to a change in inner pressure of the battery. CONSTITUTION:An electrolyte atomizer housed in a sealed lead-acid battery comprises an air sump chamber 1, a nozzle portion 2, and a cylindrical portion 5. When an inner pressure of the battery is increased, e.g. at the final period of electric charging, an inlet valve 3 is opened so that an inner pressure of the air sump chamber 1 becomes equal to that of the battery. When the inner pressure of the battery is decreased, e.g. when it is not used, the inlet valve 3 is closed so that the inner pressure of the air sump chamber 1 becomes higher than that of the battery. When the inner pressure of the battery is further decreased so that a difference between the same and the inner pressure of the air sump chamber 1 exceeds a predetermined value, an outlet valve 4 is opened so that gas of a high pressure inside the air sump chamber 1 is jetted through the nozzle portion 2. Accordingly, an electrolyte 6 stored under the battery is sucked up via the cylindrical portion 5 to be sprayed through the tip of the nozzle portion and then supplied to an electrode plate group. Consequently, it is possible to prevent stratification of the electrolyte so as to enhance the capacity and lifetime of the battery.

Title: Device, for measuring ground fault resistance, etc., in dc electric path
Inventor: AOKI TAKANORI
IPC: G01N27/18
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To prevent a relay from malfunctioning by setting the values of resistance between P-E and E-N at normal measurement equal to the values of internal resistance of the positive electrode P and negative electrode N of a 64D or greater. SOLUTION: In the case that the value of the resistance on the side of a non-ground fault electrode is set equal to the value of a 63D (a d.c. ground fault relay) or greater, and the resistance on the side of a ground fault electrode is set smaller than this at the time of secondary measurement, the resistance of the non-ground fault electrode of this invention is R21, and the resistance on the side of the ground fault electrode is the synthesized resistance of R22 and R27 equal to R21. In the case that R27 is absent, a ground fault current is equal to or smaller than the case of the 64D similarly to normal measurement.  In the case that the R27 is present, a ground fault voltage moves to the side of the ground fault electrode (V22 side) more in the case that R27 is present than in the case that R27 is absent, and a ground fault voltage becomes small in comparison with the case of the 64D and a ground fault current becomes small. In summary, by setting the resistance on the side of the non- ground fault electrode equal to the value of the 64D or greater and the resistance on the side of the ground fault electrode smaller than this, a ground fault current becomes smaller in comparison with the case that the 64D is connected to eliminate the possibility for the relay to malfunction at the time when a ground fault occurs in a relay coil circuit and to ensure safety.

Abstract: PURPOSE:To modify the surface of a film so as to give good durability thereto, by forming modifying monomer layers on both surfaces of a plastic film, covering these surfaces with sheet materials and graft-polymerizing the monomer with both surfaces of the film by irradiation with electron beams. CONSTITUTION:Liquid layers of a modifying monomer or different modifying monomers (e.g., methacrylic acid) or liquid layers of a monomer solution are formed on both surfaces of a plastic film (e.g., polyethylene film). A sheet material (e.g., paper or a plastic sheet) is laid on the surface of each liquid layer, which is irradiated with electron beams from the side of the corresponding sheet material to graft-polymerize the monomer in the liquid layer with the corresponding surface of the plastic film. The laid sheet materials are peeled from both sides of the plastic film, and unreacted monomer (solution) remaining on the surface is removed. Thus, the surface of the film can be modified.
