Abstract: A molding apparatus with die-clamping and alignment devices has a stationary die plate for holding a stationary die, a movable die plate for holding a movable die, a device for moving forwardly/rearwardly the movable die plate with respect to the stationary die plate, a fastening device for fastening the movable die plate and the tie bar to each other by hydraulic force when the stationary die and the movable die have been approached to predetermined positions, and a tie bar for clamping the movable die and the stationary die by die-clamping force generated by a die-clamping cylinder, and a primary alignment mechanism provided for at least one junction among junctions between a piston of a die-clamping hydraulic cylinder and the tie bar, between a support plate and the tie bar, and between the movable die plate and a movable die plate support member, in order to permit the two dies to be aligned to each other by a secondary position alignment function, such as a guide pie for aligning the two dies at the time

Abstract: A transverseless ship has at least its side portions and bottom portion comprised of a double hull construction which comprises an inner hull plating and an outer hull plating connected together only by transverse bulkheads and a plurality of connecting longitudinal members fixed to the bulkheads. The bottom portion of the ship has a space defined by at least two optionally selected connecting longitudinal members and divided by a partition into an upper chamber and a lower chamber. The upper chamber is adapted in its entirety to pass a fluid therethrough. With this structure, external forces acting on the ship are delivered from the connecting longitudinal members to the transverse bulkheads to prevent the inner and outer platings from buckling. The absence of reinforcing transverse members intersecting the connecting longitudinal members assures automatic welding operation with greatly improved efficiency.

Abstract: A transverseless ship has at least its side portions and bottom portion comprised of a double hull construction which comprises an inner hull plating and an outer hull plating connected together only by transverse bulkheads and a plurality of longitudinal connecting member fixed to the bulkheads. The bottom portion of the ship has a space defined by at least two optionally selected connecting longitudinal members and divided by two horizontal partitions into two upper chambers and a lower chamber. The upper chambers are adapted to pass different fluids therethrough, and the lower chamber is provided with docking brackets each conforming to the sectional shape thereof. With this structure, external forces acting on the ship are delivered from the connecting longitudinal members to the transverse bulkheads to prevent the inner and outer platings from buckling.
