Abstract: A pick-up phono cartridge in which the position of an armature disposed at a base end of a cantilever is made adjustable to thereby produce a desired output voltage. A vibrating system of the cartridge includes an armature secured to a base end of a cantilever having a stylus secured to the other end thereof. A center axis of the cantilever is vibratable around a predetermined position on the armature. A fixed system is provided including at least a front yoke and a rear yoke which are positioned to nearly clamp the armature. The vibrating system is made adjustable in the axial direction of the cantilever upon loosening a stop screw.

Abstract: A piezoelectric type pickup cartridge comprises a cantilever, an intermediate member deformable in two orthogonal directions, a press member secured to the other end of said cantilever and adapted to transmit the movement of the cantilever to the intermediate member, a piezoelectric transducing element, a damper provided between the element and the base for holding the piezoelectric element between the intermediate member and the damper.

Abstract: Building equipment for a hull comprising a hull joining stage having a bottom surface level flush with the ground level of the site; a stern building stage having a bottom surface level flush with that of the hull joining stage, provided at a longitudinal end of the hull joining stage so as to be adjacent thereto through a gate; a bow and parallel body building stage having a bottom surface level flush with that of the hull joining stage, provided at the other longitudinal end of the hull joining stage so as to be adjacent thereto through another gate; a pond having a bottom surface lower than that of the hull joining stage, provided longitudinally in parallel with and adjacent to the hull joining stage on the water side, a longitudinal end of the pond being open to a body of water through still another gate; cranes travelling linearly along the hull joining stage, the stern building stage and the bow and parallel body building stage; and partition walls higher than the ground level and the level of the body
