There is provided a battery assembly wherein assembly can be facilitated by reducing the number of components to be assembled, by integrally fixing resin plates (52, 62) on the inside of metal plates (51, 61) of end plates (5, 6). A laminated battery body (3) is constituted by adjacently arranging battery holders (2) made of resin forming cooling passages (4) between a plurality of batteries (1) and holding such batteries (1) on both sides between other batteries (1). The metal plates (51, 61) and resin plates (52, 62) that are integrally fixed on the inside of these metal plates are provided on the outside of the batteries (1) at both ends of the laminated battery body (3). Thus, the batteries (1) are held by the resin plates (52, 62), and the end plates (5, 6) are respectively arranged to form the cooling passages (4) between these batteries (1) and the metal plates (51, 61). The laminated battery body (3) is fixed in a clamped manner by fixing means clamping these end plates (5, 6).

A hand drying device includes: a drying chamber; a nozzle; a supply unit; a hand detection sensor; a control unit; and an illuminating unit. The drying chamber includes: an opening; a first inner wall surface; and a second inner wall surface facing the first inner wall surface. A hand is inserted from the opening into a space between the first inner wall surface and the second inner wall surface. The nozzle is arranged on the first inner wall surface and is configured to blow an air stream toward the second inner wall surface. A center axis of the nozzle and an optical axis of the illuminating unit intersect with each other at a proper position in the drying chamber where a hand is supposed to be inserted.

A method for producing L-glutamic acid by culturing a coryneform bacterium in which the gluX is inactivated in a medium to produce L-glutamic acid in the medium or cells, and collecting L-glutamic acid from the medium.
摘要:
In a clutch manufacturing method, inner peripheral portions of drum members, of two clutches are connected to a sleeve member, and a piston, a seal plate and a return spring are provided between the drum members, an insulator to apply electric isolation between the piston and the drum member or between the seal plate and another drum member is attached to either the piston or the seal plate. Then, the drum member, to which the electric isolation with the insulator is not applied, is connected to the sleeve member. Then, the piston, return sprig and seal plate are assembled to the sleeve member to which the drum member has been connected. Finally, the drum member, to which the electric isolation with the insulator has been applied, is connected to the sleeve member with electric welding.
