IPC: H01M2/12
Filed: 1983-11-17
Abstract: PURPOSE:To obtain a safety device having a high liquid leakage resistance and can rapidly respond to an increase in the internal pressure by using a magnetic fluid as a valve. CONSTITUTION:A gas exhaust hole 121 is provided in the upwardly expanded section of a battery lid 12. A sealing plate 13 is installed inside the battery lid 12 so that the gas exhaust hole 121 is sealed from the body of the battery.

Abstract: PURPOSE:To reduce a size between a rail and a holder and to enable reduction of the size of a device, by a method wherein a springy is located to the root of each of two arms of a holder and one circular projection is formed below the arm, the arm of the holder is inserted in an oblong hole in the wide wall of a heating chamber and the circular projection is inserted in a round hole. CONSTITUTION:Two oblong holes 1a and 1b and one round hole 1c make a pair, one pair is formed in each of four posts of upper and lower and right and left spots of each of side walls 1, positioned facing each other, of a heating chamber. Two arms 3 are situated to a holder 2 made of resin, and a springy claw 4 is situated in the vicinity of the root. A circular projection 5 is formed below the arm 3. By pressing a holder 2 in the holes formed in the side wall 1 of the heating chamber, the claw 4 of the holder is bent inwardly, and therefore, during insertion, the claw does not produce resistance. When insertion is completed, the claw of the holder is spread outwardly, and the holder is secured to the side wall of the heating chamber in a manner that the side wall of the heating chamber is nipped between the side of the holder and the claw 4. In this case, the circular projection 5 enters the round hole 1c of the side wall of the heating chamber, and the holder is prevented from rotating and floating.

IPC: H01G11/80
Filed: 1989-08-23
Abstract: PURPOSE:To prevent leakage of electrolyte by providing a gasket having an uneven part to be engaged with a part to be adhered with a separator. CONSTITUTION:When a lower gasket 3 and an upper gasket 4 are adhered by vulcanization, the edge of a separator 5 is adhered in such a manner that the edge is held between an arcuate recess 3-1 and an arcuate protrusion 4-1. Thus, the contact area of the separator 5 with the gasket is increased so that the passage of leaking electrolyte is not straight but arcuate longer than it. Accordingly, the leakage of the electrolyte is reduced. When the protrusion 4-1 is formed to be slightly larger than the recess 3-1, a force for pressurizing the separator 5 therebetween in a state adhered by vulcanization is increased to further effectively prevent leakage of the electrolyte.

Abstract: PURPOSE:To reduce the amt. of air pollutant emitted from an internal combustion engine and improve the cetane number of a fuel oil by adding, to the oil, a compd. which is an org. peroxide and simultaneously a perbasic compd. of a metal salt of an org. acid. CONSTITUTION:A compd. which is an org. peroxide and simultaneously a perbasic compd. of a metal salt of an org. acid is prepd. A perbasic compd. is such a salt compd. that the amt. of the salt-constituting metal contained is higher than equivalent to that of the salt-constituting acid contained. Such a compd. is obtd. e.g. by putting an org. acid (an unsatd. carboxylic acid is esp. pref.), a diluent (e.g. n-hexane), a metal hydroxide (a Ca salt is esp. pref.), and if necessary a perbasic accelerator (e.g. an alcohol) into a reactor, raising the temp. of the reaction system, converting it into a carbonate to thereby convert the resulting perbasic compd. into a colloidal dispersion, and blowing oxygen into the dispersion. The molar ratio of the metal to the acid is 2-40. Thus obtd. peroxide is added to a fuel oil (e.g. light oil) in a metal concn. of 20-5,000ppm, reducing the emission of soot, etc., and improving the cetane number.
