  • Patent number: 7650699
    Abstract: An electric drill having a function for preventing drilling of unexpected oblique hole. Further, in the electric drill, when the direction of drilling is displaced in drilling work using the electric drill, it is sensed automatically to stop the drilling. The electric drill (1) performs drilling in the direction perpendicular a workpiece (7) and has a tilt sensor (10) mounted on a tilt sensor mounting surface (8) defined in parallel to the ground surface. When the rotation axis (C) of the drill positioned perpendicular to the surface of the workpiece is tilted to an angle equal to or greater than a predetermined angle, the tilt sensor (10) senses the tilt to shutoff a drive current of the electric drill.

  • Publication number: 20090226790
    Abstract: A first fine particle-containing solution is deposited on an appropriate substrate, and dried to form a first fine particle aggregate layer. Polymer particles are deposited on the first fine particle aggregate layer, and are supplied with a second fine particle-containing solution such that the polymer particles are immersed in the second fine particle-containing solution. The second fine particle-containing solution is dried to form a second fine particle aggregate layer containing a large number of the polymer particles embedded. A first structure precursor is completed at this stage. Then, the first structure precursor is separated from the substrate, and thermally treated. Thus, the production of a first solid electrolyte structure, which has a porous solid electrolyte portion and a dense solid electrolyte portion integrated, is completed.
