  • Patent number: 10801451
    Abstract: A housing has an inner passage to communicate with both a fuel passage, which is to conduct fuel from a fuel pump, and a return passage, which is to return fuel a fuel tank. A valve body is movable in the housing to change a minimum flow passage cross-sectional area of the inner passage. A spring is connected to the valve body and changes its biasing load in correspondence with a fuel temperature to move the valve body. The spring moves the valve body such that the minimum flow passage cross-sectional area, when the fuel temperature is equal to or higher than a predetermined vapor generation temperature, is larger than the minimum flow passage cross-sectional area when the fuel temperature is lower than the vapor generation temperature.

  • Publication number: 20200038332
    Abstract: The present application provides an orally-disintegrating tablet having excellent tablet hardness and disintegrability. The present application further provides a method of producing a disintegrative particulate composition including three components consisting of a first disintegrator component of an acid-type carboxymethylcellulose, a second disintegrator component and an excipient. The method includes a first wet granulation step using any two of the three components, and a second wet granulation step using granules obtained in the first wet granulation step and the remaining one component of the three components not used in the first wet granulation step. The production method may further includes a crystalline cellulose as a fourth component or a third step of mixing a crystalline cellulose into granules obtained in the second wet granulation step. Disintegrative particulate compositions obtained by these methods are also disclosed.

  • Patent number: 10292934
    Abstract: An object of the present application is to provide an orally-disintegrating tablet having excellent tablet hardness and disintegrability, and including a disintegrative particulate composition. This invention relates to a disintegrative particulate composition comprising the four components consisting of a first disintegrator component of an acid-type carboxymethylcellulose, a second disintegrator component other than the acid-type carboxymethylcellulose, an excipient of a sugar or sugar alcohol, and crystalline cellulose; and to an orally-disintegrating tablet, including the disintegrative particulate composition and a medicinal ingredient.

  • Publication number: 20180235889
    Abstract: An object of the present invention is to provide an orally disintegrating tablet (super-rapid disintegrating tablet) that is heavy and relatively thin, and has an extremely high disintegrability (short disintegration time), and a high tablet hardness, and to provide a simple method for the production of said super-rapid disintegrating tablet without such a complicated process as freeze-drying. This invention relates to an orally disintegrating tablet having a specific surface area of from 1.50 to 4.00 mm2/mg and a weight of from 100 to 300 mg, particularly having a disintegration time in water of 7 seconds or less and an oral disintegration time of 6 seconds or less, a method for the production of said orally disintegrating tablet, and to a disintegrative particulate composition for use in said method.

  • Publication number: 20160213619
    Abstract: An object of the present invention is to provide an orally disintegrating tablet having both an excellent tablet hardness and disintegrability even when the content of a medicinal ingredient is high. This invention relates to an orally disintegrating tablet comprising a medicinal ingredient having distribution coefficient (log P) in a range of from ?6.0 to 10.0 and a disintegrative particulate composition produced by granulation consisting of at least two stages, especially to said orally disintegrating tablet having tablet hardness of from 30 to 100 N, and disintegration time in water of from 10 to 30 sec.

  • Patent number: 8222385
    Abstract: In order to examine whether or not a germ cell derived from a donor fish, which has been transplanted into a recipient fish of a different species by a surrogate fish technique, grows or matures in the gonad of the recipient fish, it is necessary to use, as an indicator, a trait that is specifically expressed in the germ cell and can be used to distinguish the recipient fish from the donor fish. Vasa gene, which is a germ cell-specific gene, is specific to a primordial germ cell and a spermatogonium/an oogonium, and it is not expressed in a somatic cell. In the present invention, the Vasa gene sequences of a tuna, a chub mackerel, a spotted mackerel, an eastern little tuna, and a drumfish are determined, and the expression of such gene is used as a marker for a germ cell. In addition, according to the present invention, it is possible to specifically detect only a tuna Vasa gene in Vasa gene sequences that are highly conserved in fishes, without sequencing.
