  • Publication number: 20240154181
    Abstract: An all-solid-state battery includes a negative electrode current collector foil, a solid electrolyte layer, and a positive electrode layer. The negative electrode current collector foil is connected to an insulating first elastic body having a frame shape that follows and surrounds a shape of a peripheral edge of the solid electrolyte layer. The first elastic body is connected to a main surface of the solid electrolyte layer or a side surface of the solid electrolyte layer to form an internal space surrounded by the solid electrolyte layer, the negative electrode current collector foil, and the first elastic body. The solid electrolyte layer is disposed such that an outer shape thereof includes an outer shape of the positive electrode layer inside in plan view. When the all-solid-state battery is in a fully discharged state, the internal space is filled with a negative electrode layer having electrical conductivity and/or lithium ion conductivity.

  • Patent number: 11953317
    Abstract: A reference core position calculation device 100 that calculates a reference core position of an elevator shaft in which an elevator is to be installed includes a measurement unit 101 and a calculation unit 112. The measurement unit 101 measures a dimension of each portion of the elevator shaft. The calculation unit 112 calculates portion dimension values of the elevator shaft based on the reference core position and the dimension of each portion measured by the measurement unit 101. When the reference core position is a first reference core position, the calculation unit 112 determines whether portion dimension values of the elevator shaft calculated based on the first reference core position satisfy a predetermined specification.

  • Patent number: 9350834
    Abstract: The portable telephone of the invention comprises two housings having a display screen on one of the housings, a first connection section that connects the two housings such that the housings can be opened and closed in a first direction, and a second connection section that connects the two housings such that the housings can move from an overlapped state in a second direction that is different than the first direction such that step is formed on the end sections of the housings. When the portable telephone is placed on a flat surface such as a desk, the portable telephones stably stands on its own by way of the step with the display screen facing upward at an angle. Therefore, the angle between the display screen and the line of sight of the user becomes nearly perpendicular, so the display screen is easy for the user to see.

  • Publication number: 20160116911
    Abstract: An assembly order generation device includes a radial/axial direction component detector which detects a component existing in a radial direction of a featured shape and a component existing in an axial direction of the component in a 3D CAD model. A directed graph expresses a connection precedence relationship in which the component is depicted by a node and a connection precedence relationship between the components which is depicted by a directed edge based on the detection result. A unit of disassembling and a disassembling order proposal based on the connection precedence relationship is generated, and an assembling order/direction/motion generation unit generates a disassemble direction based on the unit of disassembling and the disassembling order proposal and an assembly graph to generate a disassembling direction and a disassembling order, and reversely converts the generated disassembling direction and the generated disassembling order to derive an assembling order and an assembling direction.
