  • Publication number: 20190340389
    Abstract: In a search device (102), a data search unit (233) acquires an encrypted query including one keyword from a data storage unit (232), the encrypted query being stored in the storage unit (232) since before the encrypted data is received by the data reception unit (231). The data search unit (233) determines whether a value of the encrypted data and the keyword of the encrypted query coincide, with both of the encrypted data and the encrypted query remaining encrypted. A data transmission unit (234) transmits identification data indicating an identifier of the encrypted query when it is determined by the data search unit (233) that the value of the encrypted data and the keyword of the encrypted query coincide.

  • Patent number: 6200703
    Abstract: A vinylidene fluoride polymer binder solution for forming an electrode for a non-aqueous-type battery is formed by adding an acid, preferably an organic acid, as a stabilizer to a solution of a vinylidene fluoride polymer in an organic solvent. The acid is preferably added in an amount sufficient to ensure a pH of at most 9 when measured with respect to a 10-times dilution of the binder solution with deionized water. The acid addition is effective for preventing a problematic viscosity increase in the binder solution and also gelling of an electrode-forming composition formed by adding a powdery electrode material in the binder solution.

  • Patent number: 5589186
    Abstract: A feed composition containing fumaric acid or a salt thereof, a concentrate feed and, if necessary, a roughage is fed to ruminants. The ratio of the concentrate to the roughage is about 90-10/10-90 (% by weight). When fumaric acid or a salt thereof in a granular form such as mean particle diameter of not less than 75 mesh is added to a ration, the proportion of acetic acid and propionic acid among volatile fatty acids (VFA) in the ruminant animal is increased for a sustained time to enhance the efficiency of milk and meat production and improve the quality of meat. The proportion of fumaric acid or a salt thereof is about 0.1 to 10% by weight. The addition of fumaric acid or a salt thereof helps to suppress flatulence which tends to occur on feeding with concentrates.
