Abstract: Provided is a pharmaceutical composition that can be easily administered into the ear and has a function of allowing a drug to be retained and slowly released in the ear, a pharmaceutical composition for otic administration comprising one, or two or more drugs and a water-dispersible fine cellulose composition, in particular, microcrystalline cellulose-carmellose sodium.

Abstract: Provided is a pharmaceutical composition that can be administered into the ear without any complicated operation and has a function of allowing a drug to be retained and slowly released in the ear. A pharmaceutical composition for otic administration, comprising one, or two or more drugs and a polymer, wherein when the complex viscosity of the pharmaceutical composition is measured using a rheometer under the conditions of a shear strain of 5% and an angular frequency of 50 rad/sec., while increasing the temperature from 25° C. to 37° C. at a heating rate of 1° C./10 sec., the complex viscosity is less than 1,650 mPa·s at 25° C., and is from 1,650 mPa·s to 100,000 mPa·s at 10 minutes after reaching 37° C.

Abstract: A structure that ensures air tightness and waterproof performance of a cord insertion hole in a back cover of a lamp body. The arrangement allows a reduction of man hours for fixing a power supply cord to the back cover. In an implementation, a cylindrical outer wall 702 is provided that surrounds cord insertion holes 704a, 704b through which power supply cords 6a, 6b are inserted for sending current to light source bulbs 1a, 1b. A resin mold portion filled inside the outer wall fixes and integrates the power supply cords 6a, 6b in the cord insertion holes 704a, 704b. The resin mold portion includes a lower mold layer 9a on the side of the cord insertion holes 704a, 704b that adheres well to the back cover 7, and an upper mold layer 9b laminated over the lower mold layer 9a and having good heat resistance properties. The upper mold layer 9b prevents creep in the lower mold layer 9a, and the lower mold layer maintains air tightness and waterproof performance at the cord insertion hole.

Abstract: A protruding outer wall 702 is provided that surrounds cord insertion holes 704 (704a, 704b) used for inserting power supply cords 6 (6a, 6b) that supply current to light source bulbs 1 (1a, 1b). An inside region 705 of the outer wall 702 is filled with a soft synthetic resin 9 which is then cured. Further, inner walls 703 (703a, 703b) are provided in an interior region 705 so as to ensure air tightness and waterproof performance of the cord insertion holes 704 (704a, 704b). The structure ensures air tightness and waterproof performance of a back cover for a lamp body while reducing the number of man hours required to fix a power supply cord to the back cover.

Abstract: (2R,3R)-3-N-(L-aspartyl)amino-1-(1-methyl-2-norbornyl)-2-butanol and (2R,3R)-3-N-(L-aspartyl)amino-1-(3-methyl-2-norbornyl)-2-butanol as well as a sweetener comprising the same are disclosed. These compounds, which have excellent sweetness characteristics and are stable in acidic aqueous solutions, are highly useful as a sweetener in various fields.

Abstract: In connection with a Fresnel lens in which concentric pitch base lines are drawn on a curved lens member at certain pitches and a number of radial partitioning lines are drawn so as to pass through the center of the concentric pitch base lines and to cross these lines so that a surface of the lens member is partitioned into a large number of arcuate Fresnel step design sections, and an angled Fresnel step is formed in each of the Fresnel step design sections so that light transmitted from a focal point of the lens at its rear side forms a substantially parallel flux of light through a refractive or reflective prism, the invention relates to the cutting of Fresnel steps in a mold element for forming the lens by causing a tool attached to a multiple axis milling cutter and having an acute point to perform reciprocating or circumferential cutting for every width of each of the inclined surfaces of said Fresnel steps while causing the tool to move radially to perform scan-cutting of the inclined surfaces.
