Abstract: The present invention is made for the purpose of improving beef quality and upgrading its fat marbling standard (which is called beef marbling standard, or BMS). The fat marbling state is generally called “Shimofuri” in Japanese. This purpose is achieved by vitamin C administration (L-ascorbic acid) to the cattle. The vitamin C can be administered by injection etc., but the easiest way is by oral administration. When only the vitamin C is administered orally, however, it is decomposed by microorganisms in the rumen and the desired effect cannot be obtained. For that reason, the vitamin C needs to be coated with something so that it can be absorbed by the intestinal tract after passing through the stomach. Soybean-hydrogenated oil and fat is desirable for such covering material. An appropriate daily dose of the vitamin C is approximately 20 mg to 60 mg/kg of weight.

Abstract: The present invention relates to a high strength material and a high strength molded article including 65 to 100 wt. % of cellulose microfibrils; and products comprising these. The material, which is lightweight and has a very high strength, can be used for various purposes and can be produced by recycling wastepaper, used cloth and the like. Furthermore, by appropriately selecting the type and/or amount of binder, the material comprising microfibrils as a main component can be decomposed by microbes or the like after being dumped as waste, and is thus friendly to the global environment.

Abstract: In an optical microscope, a pair of convergence/collimation lenses are arranged on the common optical axis of a light beam directed toward a sample being observed through an objective lens, the light beam being radiated or reflected from the sample to pass through the objective lens reversely. The phase of the transmitting light beam is varied within a specified range between these lenses so that the sample is irradiated while being focused at a depth corresponding to the phase at the wave front of the light beam entering the objective lens.

Abstract: An object of the present invention is to provide an extreme ultraviolet light source target which can emits extreme ultraviolet light with high emission efficiency. A solid target made of heavy metal or heavy-metal compound and having a density 0.5 to 80% that of the crystal density is used. When the target is irradiated with a laser beam, plasma of the heavy metal contained in the target is generated, and extreme ultraviolet light having a predetermined wavelength which corresponds to the kind of the heavy metal is emitted from the plasma. When the density of the target is made to be smaller than the crystal density as described above, space distribution of the density of the generated plasma can be controlled, and the region in which plasma absorbs energy of the laser beam overlaps the region in which the plasma emits the extreme ultraviolet light. Thus, emission efficiency can be improved, preventing energy loss.

Abstract: The present invention provides a method of and a device for measuring bulk modulus of a fine specimen using a measurement chamber, a reference chamber for comparison, and a differential pressure measurement device for detecting the pressure difference between both chambers. The specimen is contained in the measurement chamber, and in a state where both chambers are set under the standard atmospheric pressure. Then both chambers are set under the compression atmospheric pressure higher than the standard atmospheric pressure and the pressure changes are periodically given to both chambers. The initial volume of the specimen is detected from the differential pressure signals of both chambers when it is under the standard atmospheric pressure and the compression volume of the specimen is detected from the differential pressure signals of both chambers when it is under the compression atmospheric pressure. The bulk modulus of the specimen is measured by computing and analyzing these detected signals.
