Abstract: Disclosed is a method and an apparatus for accelerating and shooting a flying body at superhigh speed, consisting of a capacitor in which a high electric charge can be stored; a primary coil connected to the capacitor via a switching means; a conductive cylindrical liner disposed in the primary coil; an opening defined on a cylindrical wall of the cylindrical liner; and a flying body interposed in the opening and assuming electrical continuity with the liner; wherein a high electric charge stored in the capacitor is momentarily applied to the primary coil so as to compress abruptly the cylindrical liner radially inward and to shoot the flying body interposed in the opening toward the axis of the liner.

Abstract: Disclosed is a cambering apparatus for imparting a predetermined camber to a leaf spring blank loaded between a pair of dies opposing vertically to each other by bringing the dies closer relative to each other; the apparatus comprising an upper variable die and a lower variable die; the upper variable die essentially consisting of a multiplicity of upper supporting members disposed on upper guide members to be slidable in the longitudinal direction thereof; and a multiplicity of upper shaping fingers fitted descendably in U-shaped grooves defined on the upper supporting members, respectively; whereas the lower variable die consisting essentially of a multiplicity of lower supporting members disposed on lower guide members to be slidable in the longitudinal direction thereof; and a multiplicity of lower shaping fingers fitted ascendably in U-shaped grooves defined in the lower supporting members, respectively; wherein the shaping fingers are ascended or descended to be positioned onto the supporting members re

Abstract: Disclosed is a constraining apparatus, for constraining cambered leaf spring blanks when they are quenched in an quenching oil in the oil tank of a quenching systems so as to prevent any possible distortion in the directions of the thickness and width of the blanks. The constraining apparatus basically consists of a drive system having a pair of sprockets, a drive shaft for driving the sprockets, a fixed disc and a pair of endless chains extended across the sprockets and the fixed disc, with a plurality of constrainers attached across these chains.

Abstract: Disclosed is a cambering apparatus for imparting a predetermined camber to a leaf blank for a laminated spring, which requires no change-over of molds in accordance with order changes, whereby to reduce the change-over time greatly to improve productivity.

Abstract: Disclosed is a method and an apparatus for cambering a leaf spring by pressing a heated leaf spring element or member between a pair of molds, characterized in that the pair of molds each comprises a plurality of mold fingers which can be advanced or retracted relative to the opposite mold by operating a plurality of drive means connected to the plurality of mold fingers based upon a predetermined command transmitted from a control means so as to advance or retract the fingers to required heights, respectively, so that the free ends of the mold fingers as a whole may form a required mold surface; and each mold finger is locked by a releasable locking means. The cambering apparatus may further comprise a tempering section, in which the pair of molds, together with the cambered leaf spring, are designed to be immersed within the tempering liquid contained within a liquid tank so as to effect tempering of the cambered leaf spring.
