  • Patent number: 11894574
    Abstract: A battery pack is provided with a check valve including a cover body that is attached to a housing accommodating battery cells and a valve main body that is provided at an inner side of the cover body. The check valve exhausts gas discharged from the battery cells to outside the housing. The valve main body includes a moving portion disposed at an upstream side of the cover body. The moving portion is urged by an urging member to separate to the upstream side from the main body portion. When an internal pressure of the housing is at least a threshold value, the moving portion moves to the downstream side in opposition to urging force of the urging member. Plural stopper portions of the moving portion abut against the main body portion and limit the movement to the downstream side. Interstitial flow paths for the gas are formed between the stopper portions.

  • Patent number: 9480837
    Abstract: Providing an electrode structure capable of realizing an electrode array which allows each of the electrodes to be individually controlled while allowing them to be densely arranged and placed in a living body. According to the present invention, an electrode control circuit electrically connected to an electrode body is fixed to a rear portion of the electrode body within a front-viewed contour of the electrode body. This electrode control circuit may be contained in a recess formed in the rear portion of the electrode body, or it may be fixed to the back face of the electrode body. Conversely, an electrically conductive material layer covering the electrode control circuit may be used as the electrode body. A plurality of such bioelectrodes may be arranged in a two-dimensional form on a substrate or connected by a connection line including an electrical wire. Such configurations allow the bioelectrodes to be densely arranged.
