  • Publication number: 20200111882
    Abstract: A semiconductor device includes a semiconductor layer including first and second electrode forming surfaces and side surface, an anode electrode formed on the first electrode forming surface, a cathode electrode formed on the second electrode forming surface; an insulating film continuously formed from the first electrode forming surface to the side surface so as to cover the first edge. The side surface of the semiconductor layer is covered with the insulating film, so that a leak current flowing along the side surface is reduced. Further, the side surface is protected by the insulating film, making cracking, chipping, cleavage, and the like less likely to occur.

  • Patent number: 10502369
    Abstract: The circuit board has a surface mount LED with a lens on the circuit board. A conductive portion and remaining space in the periphery of the LED are covered with solid copper foil so that reflectance of light and a heat dissipation effect are enhanced. In addition, layer structures between the circuit board and an assembled component are the same between contact portions with the assembled component so that tilt in mounting the board is suppressed. As a result, the circuit board having mounted thereon the surface mount LED having high directivity can be accurately mounted on the assembled component, tilt of an optical axis can be suppressed, the reflectance of light from the LED can be increased, and the heat dissipation effect can be enhanced.

  • Patent number: 10156576
    Abstract: The purpose of the present invention is to develop: a method for selectively separating a glycoprotein derived from the central nervous system from a body fluid or a central nervous system cell; and a method for searching for an index marker for central nervous system diseases, which utilizes the aforementioned method. A protein derived from the central nervous system, which occurs in a trace amount in a body fluid or a central nervous system cell, can be selectively enriched by a two-stage separation procedure comprising removing a glycoprotein having sialic acid at a non-reducing terminal thereof from the body fluid or the central nervous system cell and then separating a glycoprotein having N-acetylglucosamine at a non-reducing terminal thereof.

  • Patent number: 9964888
    Abstract: An incidence angle of laser light with respect to a photosensitive member in a main-scanning direction is different depending on an exposure position. Hence, the spot shape of the laser light on the photosensitive member is different in the main-scanning direction. A filter coefficient is changed in the main-scanning direction, and image data is corrected with the filter coefficient.

  • Patent number: 9914908
    Abstract: An object of the present invention is to provide a method for introducing a target substance into undifferentiated cells, and a carrier therefor, whereby the target substance can be specifically introduced into the undifferentiated cells by contacting the undifferentiated cells with an rBC2LCN-target substance fusion product in which rBC2LCN lectin is fused to the target substance. Particularly, an rBC2LCN-toxin fusion product in which rBC2LCN lectin is fused to a toxin functioning in cells or its domain having the ability to kill cells functions as an agent for eliminating undifferentiated stem cells and can be administered into a medium after inducing the differentiation of the stem cells to reliably kill only the stem cells in an undifferentiated state.
