Abstract: A full enclosed forging apparatus comprising a construction in which an upper die holder and a lower die holder are respectively disposed as to face a press machine, at least one of the upper die holder and the lower die holder is composed of a holder main body holding a die and a holder base attached to the press machine, and the holder main body is attached to the holder base through plural spring mechanisms with an aperture as an interference of the spring mechanisms as that an upper punch proceeds into the upper die and a lower punch proceeds into the lower die after the upper die held by the upper die holder and the lower die held by the lower die holder contact.

Abstract: A magneto-optic disk and a recording/reproduction device therefor adopt optical super-resolution to increase recording capacity. More specifically, the magneto-optic disk has an heat emitting layer (6) on a recording layer (4) and still preferably has an intermediate layer (8) between a reproduction layer (3) and the recording layer (4). The recording/reproduction device includes a circuit (33) for pulsing a laser beam to be radiated to the magneto-optic disk and still preferably includes a polarization rotating unit (50) and a polarizing filter (51) for blocking only the center of the laser beam in reproduction. The heat emitting layer (6) diffusing any heat generated by the laser beam, and the discontinuously radiated laser beam allow small recording domain. The laser beam having its center blocked forms smaller main lobe due to diffraction effect.

Abstract: A biaxially rotational structure for a planar antenna comprises a biaxial base having a vertical direction and a horizontal direction, a vertical shaft assembly disposed at the vertical direction of the biaxial base, the vertical shaft assembly has a rotation limiting member; a support frame pivotally mounted on the vertical shaft assembly, the support frame having a stopper extending downwardly in a manner that the rotation limiting member limits the stopper to rotate within one turn with respect to the vertical shaft assembly; a first resilient member disposed between the vertical shaft assembly and the support frame for exerting a pressing force on the support frame; a horizontal shaft assembly disposed at the horizontal direction; and a second resilient member disposed between the horizontal shaft assembly and the biaxial base for exerting a friction force therebetween.

Abstract: Elastic retaining lances (161, 162), provided in a connector housing (2), serve also as partition walls of terminal receiving chambers (3), and project into the terminal receiving chambers (3). Slanting partition walls (101, 102) are disposed rearwardly of the retaining lances (161, 162) in continuous relation thereto, and the slanting partition walls (101, 102) are continuous with horizontal rear partition walls (91, 92). Front partition walls (222, 223) are disposed forwardly of the retaining lances (161, 162), and are disposed respectively at levels equal respectively to levels of the rear partition walls (91, 92), and each of the front partition walls (222, 223) has a tapering guide surface (22a) for urging a distal end of the terminal in a direction of flexion of the retaining lance (161, 162). The distance (L4) between the front partition walls (222, 223) is at least the sum of a height of the terminal and a margin (L1) for the flexion of the retaining lance (161).
