  • Patent number: 11837741
    Abstract: The electrical apparatus, in which a series connection state and a parallel connection state of an upper cell unit including five battery cells and a lower cell unit can be automatically switched by means of a difference in a terminal shape on the electrical apparatus body side, has a terminal holder and holds apparatus side terminals. The terminal holder, which establishes an electrically connected state with the connection terminals of the battery pack, is provided with two parallel protruding parts that extend in the forward-backward direction, and second rail grooves fitted to the protruding parts on the electrical apparatus side. Due to the fitting, relative movement of the terminal holder and the battery pack in the vertical direction can be suppressed, and wear on the apparatus side terminals can be greatly suppressed.

  • Patent number: 11824169
    Abstract: A battery pack houses first and second cell units that are composed of a plurality of cells, and has a positive electrode power source terminal and a negative electrode power source terminal. This battery pack is provided with a series connector capable of connecting, in series, the first and second cell units and a parallel connector capable of connecting, in parallel, the first and second cell units, and is capable of switching between a parallel connection voltage and a series connection voltage. In the case of attachment to the high voltage electrical device body, the series connector becomes conductive and the parallel connector pair is cut off by the action of the series/parallel switching terminal. In the case of attachment to a low voltage electrical device body, the state is returned to an initial state, the series connector is cut off, and the parallel connector pair becomes conductive.

  • Publication number: 20230287165
    Abstract: A layer contains a block copolymer in which a microphase-separated structure of the block copolymer has been induced to be perpendicular to a substrate, the process being difficult to perform by means of heating at atmospheric pressure. A method produces this layer. A method produces a semiconductor device in which a vertically phase-separated block copolymer layer is used. The vertically phase-separated block copolymer layer is formed by heating under a pressure below atmospheric pressure and at a temperature at which induced self-assembly can occur. It is preferable that the vertical phase separation includes a lamellar portion. It is preferable that the lamellar portion includes PMMA. It is preferable that the heating temperature is 290° C. or higher. It is preferable to additionally have a layer, which neutralizes the surface energy of the block copolymer, beneath the block copolymer layer.
