  • Publication number: 20210328302
    Abstract: A electrode body of a power storage cell is accommodated in an inner space of a housing to form an upper clearance on a side opposite to a bottom surface of the housing and form a side clearance between the electrode body and each of a first side surface and a second side surface of the housing. Gas discharge valves include a first discharge valve provided on the first side surface and a second discharge valve provided on the second side surface. At least a portion of an opening of the first discharge valve is located at a region of the first side surface to which the upper clearance is projected, and at least a portion of an opening of the second discharge valve is located at a region of the second side surface to which the upper clearance is projected.

  • Patent number: 8435667
    Abstract: In an assembled battery (10), a plurality of rechargeable unit cells (12), each of which is provided with an electrode body (30) that has a positive electrode (32) and a negative electrode (34), a container (14) that houses the electrode body (30) and an electrolyte, and a positive electrode terminal (15) and a negative electrode terminal (16) which are arranged on an outside of the container (14), the rechargeable unit cells being connected in series. The plurality of unit cells (12) are arranged in a predetermined direction and fastened together while a predetermined load is applied in the arranging direction. Insulating filler (25) is inserted into a gap between the electrode body (30) and an inside wall surface of the container (14) of at least one of the unit cells (12), and a thickness in the arranging direction of each of the unit cells (12) in the fastened state is constant.

  • Patent number: 7863409
    Abstract: A separation object including at least two types of resins with different glass transition temperatures (glass transition temperature of a first resin 1<glass transition temperature of a second resin 2) is placed on a separating member 3. Next, primary heating is applied at a temperature between the glass transition temperatures of the first resin 1 and the second resin 2, and pressurization is additionally performed to cause the first resin 1 to adhere to the separating member 3. Subsequently, a heat history of secondary heating at a temperature higher than the primary heating temperature is applied to detach and recover the second resin 2 by restoring the shape of the second resin 2, while the first resin 1 adhering to and retained by the separating member 3 is detached by a blade 5 and the like for recovery.

  • Patent number: 6320310
    Abstract: In an image display apparatus comprising a fluorescent layer formed on the inner surface of a vacuum container, an electron emission source, and a supporting member sandwiched between the fluorescent layer and the electron emission source so that the fluorescent layer and the electron emission source are kept in parallel, a displacement preventing system is provided to prevent displacement of the electron beams emitted from the electron sources caused by the charging of the supporting member. More specifically, the supporting member may be composed of an insulating portion contacting with the electron emission source and a conducting portion contacting with the fluorescent layer. An electrode portion may be provided between the insulating portion and the conductive portion. Electron sources are arranged on the insulating substrate so that the electron beams emitted from the electron sources will be landed on the fluorescent layer with an equal pitch.
