An aircraft fuselage including at least two sections kept assembled at a circumferential join, each section having at least one panel. The circumferential join includes at least one inner ring, situated on one face, called the inner face, of the fuselage. The inner ring has a width li, partially overlaps each of the two panels and is fixed to the two panels by fasteners. The fuselage also includes an outer ring, situated on one face, called the outer face, of the fuselage, opposite to the inner face. The outer ring has a width le, partially overlaps the two panels, and is fixed to the two panels and to the inner ring by some or all of the fasteners fixing the inner ring to the two panels.

A lithium secondary battery 10 is provided with an inner electrode body 1 comprising a positive electrode plate and a negative electrode plate respectively made up of at least one metal foil 6 wound or laminated; said inner electrode body being impregnated with a non-aqueous electrolyte, current collector members 5A and 5B for leading a current out of this inner electrode body 1, a battery case 11 with both ends left open; said battery case housing the inner electrode body 1, and two caps 13 provided with internal terminals 14A and 14B thereon; said caps being used to seal the inner electrode body 1 at both open ends of the battery 11. By adopting such a configuration that positive and negative external terminals are placed on one end of a battery collectively, protrusions of the battery are so reduced that the collective coupling of batteries becomes easier.

A conductance valve is configured to be able to adjust the conductance by adjusting the opening degree of an opening formed in part of the wall surface a vacuum vessel. The conductance valve includes a swing arm which is pivotally coupled to a driving portion, and a rectangular valve body which is coupled to the swing arm and is pivotal with respect to it. When the swing arm pivots, the rectangular valve body is pivoted by a predetermined angle. The overhang of the valve body at the closed position of the conductance valve can be reduced.

A motor-driven supercharger is provided with a thrust bearing (30) rotatably supporting a thrust force applied to a turbine shaft (12). The thrust bearing (30) is constituted by a small-diameter disc-shaped thrust collar (32) rotating together with a turbine shaft, and a turbine side thrust bearing (34) and a compressor side thrust bearing (36) which block a movement in an axial direction of the thrust collar. The compressor side thrust bearing (36) has a small-diameter ring portion (37) including a thrust surface which is in contact with the thrust collar and has approximately an equal diameter, and a flange portion (38a) fixed to a housing (16) in the turbine side, and the small-diameter ring portion and the flange portion are arranged at different positions in an axial direction.

The invention discloses an inverted numerically-controlled lathe provided with two separated shafts. The lathe comprises a lathe body, wherein transverse guide rails are fixedly arranged at the upper end of the lathe body and are three horizontal guide rails triangularly arranged in space, a horizontal slide saddle capable of transversely moving along the transverse guide rails is mounted on the transverse guide rails, and a spindle component unit is mounted on the horizontal slide saddle and comprises a spindle and a spindle chuck arranged at the lower end of the spindle; longitudinal guide rails are fixedly arranged on the lathe body below the transverse guide rails and are three vertical guide rails triangularly arranged in space, a vertical slide saddle capable of longitudinally moving along the longitudinal guide rails is mounted on the longitudinal guide rails, and a tool rest is mounted on the vertical slide saddle; a feeding device and a discharging device are arranged on the lathe body on two sides of the longitudinal guide rails respectively. The guide rails adopt three-dimensional layout in the space, the rigidity of the inverted numerically-controlled lathe is increased, the spindle and the tool rest are used as two feed shafts to move, feeding and discharging of workpieces are realized, and the precision and the stability of the numerically-controlled lathe are improved.
