  • Publication number: 20110317813
    Abstract: A wavelength-classifying type X-ray diffraction device bombards a sample with characteristic X-rays generated from an X-ray generation source, and detects characteristic X-rays diffracted by the sample using an X-ray detector. The X-ray generation source is composed of several metals of different atomic number, respective metals generating several characteristic X-rays of different wavelengths. An X-ray detector is composed of several pixels for receiving X-rays and outputting pulse signals corresponding to X-ray wavelengths. Pixels are respectively furnished with classification circuits. The classification circuits classify and output pixel output signals based on each of characteristic X-ray wavelengths. X-ray intensity is detected on a per-wavelength basis in individual pixels 12. Measurement data based on different wavelength X-rays are acquired simultaneously in just one measurement.

  • Publication number: 20110150500
    Abstract: A vertical cavity surface emitting laser that includes: a substrate; a first semiconductor multilayer reflector; an active region; a second semiconductor multilayer reflector; a columnar structure formed on the substrate; a current narrowing layer that is formed inside of the columnar structure, and has a conductive region surrounded by an oxidization region selectively oxidized; a first electrode that is formed at a top of the columnar structure, and defines a beam window; a first insulating film that covers the beam window; and a second insulating film of which a second refractive index is larger than the first refractive index. A reflection ratio in a second region where the second insulating film is formed is lower than a reflection ratio in a first region where only the first insulating film is formed.

  • Patent number: 7957447
    Abstract: Provided is a VCSEL array device that includes at least a first multilayer reflective film, an active layer, and a second multilayer reflective film, formed on a substrate that extends in a longitudinal direction. Plural mesa portions are formed on the substrate by selectively removing at least a portion of the first multilayer reflective film, active layer, and second multilayer reflective film. A selectively oxidized region is formed in at least one of the first multilayer reflective film and the second multilayer reflective film. The VCSEL array device further includes an interlayer insulating film that covers at least a side portion and a bottom portion of the mesa portions, and a surface protecting film that covers the interlayer insulating film. The surface protecting film has plural grooves formed along a longitudinal direction of the substrate in which at least a portion of the surface protecting film is removed.

  • Patent number: 7897562
    Abstract: An object of the present invention is to provide a novel means for stably and surely inducing cell apoptosis using the c-myc gene as a target. The present invention relates to an apoptosis-inducing agent containing a protein that interacts with an FBP protein or a polynucleotide encoding the protein as an active ingredient and a method for inducing apoptosis, which comprises a step of causing the apoptosis-inducing agent to come into contact with cells.
