摘要:
A method for producing an optically active erythro-3-amino-2-hydroxybutyric ester as an important intermediate of pharmaceutical agents, specifically HIV protease inhibitor, in high purity and in high yield. The method includes producing an optically active erythro-3-amino-2-hydroxybutyric ester by oxidizing the hydroxyl group at the 2-position of an optically active 3-amino-2-hydroxybutyric ester, optically active at the 3-position, as represented by formula (I): ##STR1## (wherein R.sup.1 represents a phenyl group or a cyclohexyl group; R.sup.2 represents a protective group and R.sup.3 represents an unsubstituted or substituted alkyl residue; the steric configuration of *1 represents S configuration or R configuration), and then reducing erythro-selectively the resulting product by using aluminum alkoxide.

A method of a computer, the method including the computer authorizing, not only a first user, but also a second user to access data that is created by the first user and is stored in association with a community. Wherein the first user is registered as a member who belongs to a group, wherein a member belonging to the group is authorized to access data that is accessibly stored for the member of the group, and the second user is defined as a superior of the first user in organization information that indicates hierarchical-relation of users and does not belong to the group. The computer rejects access to the data for an additional user, wherein the additional user has been determined not to be within a publication range of the data, even though the user is within a publication range of the community to which the data belongs.

An adhesive sheet is provided in which properties that cause corrosion of a non-contacting metal are inhibited. The adhesive sheet is provided with a pressure-sensitive adhesive layer formed from an aqueous dispersion type adhesive composition. The pressure-sensitive adhesive composition contains an aqueous dispersion type acrylic polymer synthesized using a chain transfer agent that does not have sulfur as a composite element thereof. The amount of sulfur-containing gas (as SO42−) released from the pressure-sensitive adhesive sheet in the case of heating for 1 hour at 85° C. is 0.043 μg/1 cm2 or less, adhesive strength on an ABS sheet is 10 N/20 mm or more, and holding time as determined in an 80° C. cohesive strength test is 1 hour or more.

(Problem) The object of the invention relates to a development of a new musk-feeling fragrance material which is a highly scenting musk-feeling fragrance, and is to provide a fragrance composition which, when added to fragrances or cosmetics, can improve the fixative property and express a high performance and excellent musky aromatic quality.(Means for resolution) A fragrance composition is prepared using, as the active ingredient, a mixture of (R)-form of optically active muscone with (S)-form of optically active muscone with the mixing ratio thereof within the range of from 90:10 to 95:5 (weight ratio) in terms of weight ratio, or a mixture of (R)-form of optically active muscone with (S)-form of optically active muscone with the mixing ratio thereof within the range of from 75:25 to 80:20 (weight ratio) in terms of weight ratio.
摘要:
The present invention provides a vehicle display device which can display fuel consumption information of a vehicle in a useful and optimum mode for a driver. A meter_EUC calculates an instantaneous fuel consumption of a vehicle based on a mileage and a fuel injection quantity within a set time, calculates an average fuel consumption of the vehicle based on respective cumulative values of the mileage and the fuel injection quantity repeatedly calculated for every set time, and displays the deviation of the instantaneous fuel consumption with respect to the average fuel consumption as fuel consumption information on a fuel consumption meter. The display on the fuel consumption meter is performed by swinging a pointer with respect to a neutral position. When the deviation takes a positive value, the pointer is swung in the pulse direction with a swinging width corresponding to the deviation quantity, while when the deviation takes a negative value, the pointer is swung in the minus direction with a swinging width corresponding to the deviation quantity.

A driving force control device can set driving force characteristics which conform to tastes of drivers using one vehicle thus giving the easy-to-drive feeling to the drivers. An E/G13ECU possesses three modes 1 to 3 as control modes and selects one mode from these modes based on a manipulation input using a mode selection switch. Further, any one of the mode out of these modes 1 to 3 is preset in the E/G13ECU as a temporary changeover mode, and the E/G13ECU changes over a mode selected by the mode selection switch and the preset temporary changeover mode alternatively by the temporary changeover switch.

摘要:
A plasma display panel has a good productivity of partition formation and air exhaustion process and realizes a bright and stable display. A discharge gas is filled in a gap between two substrates. A mesh-patterned partition is arranged on the inner surface of one of the substrates for dividing the gap into plural squares corresponding to a cell arrangement. The partition has low portions forming a mesh-like air path that travels through all of the gas-filled space enclosed by the partition, in a plan view. A plasma display panel includes two spaced substrates defining a gap therebetween. The gap is divided by intersecting walls into columns and rows of discharge cells. Portions of a wall that are lower in height than remaining portions of the wall define a flow path. The plasma display panel realizes a bright and stable display.
