Abstract: An electrostatic separation method includes: applying voltage between a lower electrode at a bottom portion of or in the raw material layer and an upper electrode above the raw material layer, generating an electric field between electrodes; fluidizing the raw material layer and bringing conductive particles and the lower electrode into contact in the raw material layer charging only the conductive particles wherein their polarity becomes the same as the lower electrode; generating polarity, the same as the upper electrode, by dielectric polarization on a conveyor belt downward-facing conveyance surface passing through a capture region above the raw material layer and under the upper electrode, the conveyance surface including a nonconductor; separates charged conductive particles from the raw material layer surface by electrostatic force and adhering conductive particles to the conveyor belt conveyance surface; and separating and collecting the particles from the conveyance surface that moved outside the ele

Abstract: A component supplying apparatus which is appended to the electronic component working apparatus, for supplying electronic components to the electronic component working apparatus is provided. The component supplying apparatus includes a component storing section which stores the electronic components, and movement range regulator. The movement range regulator allows the component storing section to move between a supply position P1 which is set for supplying the electronic components and a retracted position P2 to which the component storing section is retracted for the purpose of maintenance of the electronic component working apparatus. In addition, the movement range regulator regulates the range of relative movement of the component storing section with respect to the electronic component working apparatus to a movement amount L4 that is previously established.

Abstract: The present invention intends to provide a solar cell that has, by an increase in the absorbance of light of a surface of a solar cell, a reduction in the reflectance, and so on, a high energy conversion efficiency. The problem was solved by a pn junction type semiconductor solar cell that has a porous structure on a surface thereof, characterized in that metal nanoparticles having a surface plasmon absorption are supported in pores present in the porous structure, further, by a pn junction type semiconductor solar cell in which the porous structure is formed in a photoelectric material itself in a pn junction type semiconductor solar cell, or, the porous structure is formed in a light transmission layer disposed on a surface of a pn junction type semiconductor solar cell.

Abstract: A solid oxide cell is provided which, after short-time activation, can generate electricity at a high power density over a prolonged period. This cell can be constituted so as to eliminate the necessity of carrier gas introduction during power generation and, hence, can more easily realize a size reduction in power generation systems.
