摘要:
A wheel bearing includes a sealing device 5 positioned between inner and outer members 1 and 2. This sealing device 5 includes an elastic member 14, which eventually forms an encoder grid and is provided on a first annular sealing plate 11. A second annular sealing plate 12 is provided with sealing lips 16a to 16c. An engagement 18 between a cylindrical wall 11a of the first annular sealing plate 11 and the inner member 1 is provided with an elastic member 20 made of a material dissimilar to that for the elastic material 14. This elastic member 20 may be a rubber coated layer, resin paint layer, a thin film of adhesive material or a ring-shaped rubber member. Thereby, any possible ingress of water across an engagement surface of the annular sealing plate is prevented, accompanied by increase of the lifetime of the bearing, with no problem associated with separation and displacement of the annular sealing plates. The magnetic flux density can also be easily secured.

The present invention relates to a novel chalcone compound represented by the following general formula: wherein R1 and R2 are taken together with the carbon atom to which they are bound, respectively, to form a hydroxydimethyl hexane ring, or where R1 is a hydroxyl group, R2 is an isohexenyl group, a derivative thereof, or a salt thereof. Also, the present invention relates to a therapeutic agent or prophylactic agent for a disease requiring neuronal protection, suppression for nitrogen monoxide (NO) production, inhibition for aldose reductase or suppression for interleukin production, and a food, beverage or feed for treatment or prevention of the above-mentioned disease, characterized in that each comprises the above-mentioned compound as an effective ingredient.
摘要:
The present invention relates to a therapeutic agent or prophylactic agent for a disease requiring enhancement of nerve growth factor (NGF) production upon treatment or prevention, an enhancing agent for nerve growth factor production, and a food, beverage or feed for enhancing nerve growth factor production, characterized in that each comprises as an effective ingredient a compound selected from the group consisting of soyasaponin compounds, soyasapogenin compounds, glycyrrhizin and salts thereof. In addition, the present invention relates to a novel soyasaponin compound and a novel soyasapogenin compound, having an action for enhancement of NGF production.
摘要:
A method for optical resolution of a DL-amino acid comprising reacting the DL-amino acid with an optically active N-acyl aspartic acid in a solvent or mixture of solvents, and separating the resulting two diasteromeric salts by way of the difference between their solubilities in the solvent or mixture of solvents. The difference in solubility may be enhanced by cooling, concentration, addition of a solubility-decreasing organic solvent, pH adjustment or salting out.
摘要:
The present invention provides a novel chalcone compound, its derivative or a salt thereof, each having a suppressive action of NO production or an inhibitory action of aldose reductase. In addition, the present invention provides a medicament, a food, a beverage or a feed having a therapeutic or prophylactic effect for a disease showing sensitivity to the compound, by utilizing the physiological actions of the compound.
摘要:
According to the present invention, there are provided kneading-free Angelica keiskei tea leaves obtainable by a treatment comprising a step for roast-heating a dried material of Angelica keiskei; an Angelica keiskei tea beverage produced by using the kneading-free Angelica keiskei tea leaves; and a process for producing thereof. The Angelica keiskei tea leaves are preferably heated at a heating temperature of 100° C. to 150° C. in the roast-heating treatment, and the dried material of Angelica keiskei to be subjected to the roast-heating is preferably obtained by drying in a dried system after blanching and has a moisture content of 20% or less. Further, according to the present invention, there is also provided an Angelica keiskei chalcone function-formulated beverage comprising formulated Angelica keiskei chalcones that are components specific to Angelica keiskei.
