摘要:
A light-emitting diode (1) is furnished with a semiconductor laminate (6), optically reflective layers (17) and (19), an optically reflective film (25), and a phosphorescent plate (27). The laminate (6) is formed by an n-type cladding layer (9), an active layer (11), a p-type cladding layer (13), and a p-type contact layer (15), laminated in order onto a substrate (7). The optically reflective layers (17) and (19) are provided respectively on the p-type contact layer (15) and on the back side (7b) of the substrate (7). The optically reflective film (25) is provided on three side surfaces of the laminate (6). The phosphorescent plate (27) is mounted on a side face, among the side faces of the laminate (6), on which there is no optically reflective film (25). Blue light (L1) output from the active layer (11) is reflected at each of the optically reflective layers, and is gathered on the side face on which the phosphorescent plate (27) is provided. A portion of the blue light (L1) turns into yellow light (2) in the phosphorescent plate (27), and white light derived from the blue light (L1) and yellow light (L2) is emitted.

摘要:
To provide a heater module which can improve the temperature uniformity in an optical waveguide while keeping the power consumption and the thickness of the optical waveguide module. A heater module 20 in accordance with the present invention is a heater module 20 for heating an optical waveguide device 12 so as to regulate its temperature; and comprises a heat-generating circuit 22 adapted to generate heat when energized, and a heat-transmitting section 21 disposed on the upper face of the heat-generating circuit 22 and formed with a recessed groove portion for mounting the optical waveguide device 12. When the optical waveguide device 12 is mounted on the bottom face of the heat-transmitting section 21 formed with the recessed groove section, the optical waveguide device 12 can be heated not only from its bottom face, but also from its side faces by edge parts constituting the recessed groove portion, whereby the temperature uniformity can be enhanced.

A storage device is disclosed. The storage device includes a text/image information memory unit, a unit that converts the data format of text/image information, a unit that communicates with a user terminal having a display, and a delivery unit configured to, in response to a request for the property of a file stored in the memory unit from the user terminal through the communication unit, show the property of the corresponding file stored in the memory unit on the display of the user terminal. When the user terminal requests a download of the file by selecting a file format applicable to binary image data, the conversion unit converts text/image information contained in the file into binary image data if the data format of the text/image information is not binary image data but is multilevel image data (color image). Then, the delivery unit sends the binary image data in the selected file format to the user terminal.
摘要:
Genes whose expression differ between that in eosinophils collected from atopic dermatitis patients of the exabartation stage and those of the remission stage were searched via a differential display method. As a result, NOR-1 (MINOR) gene was successfully identified whose expression significantly increased in eosinophils of patients in the remission stage, a stage associated with a decrease of eosinophils. The present inventors discovered that the gene can be successfully employed in testing for allergic diseases and screening for candidate compounds for therapeutic agents.

The semiconductor layer and electrodes are formed such that an emission region into which carriers flow in the emission layer is located above and within the span of the low dislocation density high conductance region. Thus, a surface-emitting laser element having uniform light emission at the emission region can be obtained with favorable yield.
