  • Self-renewal promoter for neural stem cells and method for using same
    Patent number: 9394516
    Abstract: An object of the present invention to provide an agent for promoting the self-renewal of the neural stem cells and a method of using the same. ECF-L contained in a culture supernatant of endothelial progenitor cells derived from bone marrow has an effect of promoting the self-renewal of neural stem cells. Accordingly, ECF-L can be used as an ingredient of an agent for promoting the self-renewal of the neural stem cells, a pharmaceutical composition for growing the neural stem cells, and a pharmaceutical composition for treating a disease associated with neural dysfunction.

  • Electronic board system and coordinates-inputting pen
    Patent number: 6700129
    Abstract: The present invention transmits, to an electronic board controller 14, click signals generated upon manipulating multiple switches provided on a coordinates-inputting pen 13, timing signals upon detecting infrared scanning beams 18a and 18b, and the like without using a connecting wire. Specifically, light-emitting elements are provided which can emit visible or infrared light to the coordinates-inputting pen 13. A timing signal upon detecting the infrared scanning beam with the pen and a click signal generated upon manipulating the switch on the pen are sent out on a modulated light 19 to be received by a light receiver 20 arranged at a fixed position and transmitted to the electronic board controller 14.

  • Coordinate input pen, and electronic board, coordinate input system and electronic board system using the coordinate input pen
    Patent number: 6437314
    Abstract: The present invention relates to a coordinate input pen for specifying and outputting coordinates of the pen by detecting two infrared beams that are emitted from two separate positions for pivotally scanning over a plane parallel to a surface of a display panel. The coordinate input pen includes: a shaft portion; a transparent conical light scattering member with a rough surface, which is, placed at the end of the shaft portion; and a light receiving element for detecting an infrared beam scattered within the light scattering member.
