摘要:
An optical amplifying apparatus of the present invention comprises a correction part for correcting a predetermined fixed value of an output optical level by a correction amount according to an optical power of amplified spontaneous emission (ASE). The correction amount is, for example, computed by predetermined formulas. According to the present invention, when a WDM optical signal is optically amplified, the output is fixedly amplified for each channel by the correction amount which is a value obtained with the ASE levels taken into consideration, so that a fluctuation in the level of the average optical power of the channels is suppressed even if an optical signal is dropped/added therefrom/thereto during repeated transmissions.

The present invention relates to a solar collector for obtaining high temperature thermal energy by collecting solar energy, especially to the improvement of performance and safety of an absorber tube containing thermal energy storage material. Precisely, the solar collector has a double tube structure at the focal line of a solar concentrator where thermal energy storage material changeable from a solid phase to a liquid phase is enclosed in the space between the inner tube and the outer tube, heat transfer fluid is introduced through the inner tube and the outer surface of the inner tube and the inner surface of the outer tube have partial contact with each other. Consequently, in accordance with the present invention, a part of the absorbed solar energy is transferred directly to the inner tube without passing through the thermal energy storage material and heats the heat transfer fluid efficiently because of the direct contact of the inner and outer tubes.

A rare-earth element including a magnet body containing a rare-earth element, and a protective layer formed on a surface of the magnet body. The protective layer may include a first layer covering the magnet body and containing a rare-earth element, and a second layer covering the first layer and containing substantially no rare-earth element. Another protective layer in accordance may include an inner protective layer and an outer protective layer successively from the magnet body side. The outer protective layer is any of an oxide layer, a resin layer, a metal salt layer, and a layer containing an organic-inorganic hybrid compound.

A planar object to be processed 1 comprising a hexagonal SiC substrate 12 having a front face 12a forming an angle corresponding to an off-angle with a c-plane is prepared. Subsequently, the object 1 is irradiated with pulse-oscillated laser light L along lines to cut 5a, 5m such that a pulse pitch becomes 10 μm to 18 μm while locating a converging point P of the laser light L within the SiC substrate 12. Thereby, modified regions 7a, 7m to become cutting start points are formed within the SiC substrate 12 along the lines 5a, 5m.

Arteriosclerosis induces cerebral infarction and myocardial infarction. A multi-marker (a group of protein markers) that assesses the accurate pathogenesis of arteriosclerosis and enables the selection of an adequate treatment method for arteriosclerosis and prediction of the progression of arteriosclerosis, and an evaluation method for the diagnosis, prevention, and treatment of arteriosclerosis that uses said marker group as an indicator have been sought. The present invention relates to A method for evaluation of arteriosclerosis comprising the steps of (a) measuring the expression of von Willebrand factor and/or complement factor D in a sample derived from a subject, (b) measuring the expression of complement component C8 and/or vitamin K-dependent protein Z in the sample derived from the subject, and (c) evaluating arteriosclerosis in the subject on the basis of the results from (a) and (b).

The rare earth magnet 1 according to the present invention to solve the above problems includes a magnet body 10 containing rare earth elements, a substantial amorphous layer 20 formed on a surface of the magnet body 10, and a protecting layer 30 on a surface of the amorphous layer 20, and the amorphous layer 20 contains material identical to main component elements of magnet material contained in the magnet body 10.
摘要:
Fractures (17a, 17b) are generated from modified regions (7a, 7b) to front and rear faces (12a, 12b) of a object to be processed (1), respectively, while an unmodified region (2) is interposed between the modified regions (7a, 7b). This can prevent fractures from continuously advancing in the thickness direction of a silicon substrate (12) when forming a plurality of rows of modified regions (7). By generating a stress in the object (1), the fractures (17a, 17b) are connected to each other in the unmodified region (2), so as to cut the object (1). This can prevent fractures from meandering in the rear face (12b) of the object (1) and so forth, whereby the object (1) can be cut accurately along a line to cut the object (5).
摘要:
An optical node disposed along a transmission line that uses optical fiber. The optical node includes a first signal generator and a monitor. The first signal generator generates a first measurement signal for measuring polarization mode dispersion values and transmits the first measurement signal along the transmission line. The monitor detects a second measurement signal from the transmission line and measures polarization mode dispersion values by performing signal processing with respect to the second measurement signal.
