Abstract: PROBLEM TO BE SOLVED: To provide a substrate, a device and a method for detecting fluorescence, which improve the reflectivity of control light.
SOLUTION: A disk-shaped DNA chip is made up by laminating a surface layer 5 where a target DNA and a fluorescent labeling agent can fall in drops from its surface side, and a probe DNA can be immobilized thereto, and a plurality of cells 6 being fields of cross reactions between the probe DNA and the target DNA are formed thereon; a first light transmitting layer 4 which is formed on the lower layer of the surface layer 5; and a plate-like second light transmitting layer 3 which is formed on the lower layer of the first light transmitting layer 4. The second light transmitting layer 3 is irradiated from its rear face side with stimulating light for fluorescence of the fluorescent labeling agent and with the control light used for projecting the stimulating light onto a desired position. The first light transmitting layer 4 has a refractive index value higher than that of the second light transmitting layer 3 and that of solution remaining in the cell 6 after the cross reaction between the probe DNA and the target DNA.

Abstract: PROBLEM TO BE SOLVED: To provide a high luminance, high-resolution, and thin display device which does not consume much electric power, and an illuminator thereof. SOLUTION: In a color display device which is provided with a GaN-based light-emitting diode array on a substrate 1 and a red phosphor 5, a green phosphor 6, and a blue phosphor 7 correspondingly to each GaN-based light-emitting diode 2 and causes the phosphors phosphors 5, 6, and 7 to emit light by exciting the phosphors 5, 6, and 7 with light emitted from each diode 2, the phosphors 5, 6, and 7 are constituted of crystals having crystal grain diameters, which are twice that of the exciton Bohr radius or smaller. It is also possible to use the blue light rays emitted from the diodes as they are without providing the blue phosphor 7. When a white phosphor is used, a white illuminator can be obtained.

Abstract: PURPOSE:To surely decrease noises and to provide higher-density tracks. CONSTITUTION:The magneto-optical recording medium 20 constituted to reproduce recording information of an optical reproduction limit or more by having at least a reproducing layer 11 and a recording layer 12 on a substrate 31 and transferring the magnetic domains, i.e., recording marks, of the recording layer 12 to the reproducing layer 12 by utilizing the heating up by the light with which the recording layer is irradiated at the time of reproducing, then reading out these marks is provided. The smooth surface region formed by transfer of the glass surface of a glass master disk for forming such substrate 21 in the magneto-optical recording medium to be used for MSR-RAD is used as the information recording region.

Abstract: PURPOSE:To carry out reproduction with high C/N, little cross talk and little distortion of output wave-form. CONSTITUTION:This magneto-optical recording medium 10 has a magneto-optical recording layer 21 having a polycrystalline structure and consisting essentially of a reproducing layer 11, a recording layer 13, a middle layer 12 and a reproduction assisting layer 31 held between the layers 11, 13. The magneto-optical recording layer 21 is irradiated with a beam of light, the reproducing layer 11 is heated by the irradiation and a signal magnetically recorded in the recording layer 13 is read out while being transferred to the reproducing layer 11. In this magneto-optical recording medium 10, the Curie temp. of the reproduction assisting layer 31 is set above the temp. of the irradiated part of the magneto- optical recording layer 21 at the time of readout.

Abstract: PURPOSE:To realize ultra-high resolution and simplified recording without necessity of erasing process by utilizing a magneto-optical recording medium comprising a multilayer magnetic film which can be formed by sequentially stacking a reproducing layer, a memory layer and a recording layer. CONSTITUTION:A magneto-optical recording medium 5 is formed by depositing a multilayer magnetic film 3 and a protection film 4 on a substrate such as light transmissive glass substrate, resin substrate or the like through a dielectric material film 2. For reproduction of recorded information, magnetization of reproducing layer is arranged uniformly in the reproducing magnetic field direction disabling readout operation of recorded information within the high temperature region due to temperature distribution in the reproducing light spot and limitedly recorded information can be read in a low temperature region. Thereby, recording can be simplified because the process which once erases total magnetic layer is no longer necessary.
