Abstract:
A spherical bearing assembly manufacturing apparatus and its manufacturing method is disclosed. The spherical bearing that houses and supports a spherical journal is manufactured with fiber reinforced composite as a material. The spherical bearing assembly manufacturing apparatus consists of a mold, plunger, and first and second grippers. The mold has a cavity for molding fiber reinforced composite into a spherical bearing, and a first press surface for supporting fiber reinforced composite, and a first guide hole communicated with the cavity. The plunger has a second press surface for molding the fiber reinforced composite housed in the cavity into a spherical bearing, and a second guide hole formed in the center of the second press surface. In the first gripper is formed a hole in which the edge on one end of the spherical journal is housed. In the second gripper is formed a recessed portion in which the edge on the other end of the spherical journal is housed.
Abstract:
A corner panel of an LNG cargo that includes a main body, which forms a corner area of the cargo, and a stress diverging part, which reduces the convergence of stress of the main body by being integrated with an internal face of the main body and being formed with curvature, and a secondary barrier formed in a curved shape.
Abstract:
A probe card is used in conducting a visual test for a target test object through simultaneous contact of the probe card with each and every electrode pad of the target test object. The probe card includes a plurality of probes composed of conductive wire strands and having elastically deformable contact parts so curved as to make contact with electrode pads of a target test object. The contact parts are oriented in one and the same direction and extend in a parallel relationship with one another. The probe card further includes a first insulating block for fixedly securing one end parts of the probes, a second insulating block for fixedly securing the other end parts of the probes and a mounting plate for holding the first and second insulating blocks in such a manner that the contact parts of the probes protrude outwardly.
