    摘要: A beaded edge is formed on a plate member, which has an upstanding outer edge bent with a predetermined radius of curvature, by placing the plate member on a lower die and applying a uniform force against the free edge of the upturned portion at an approximately 45.degree. angle to turn the outer portion inwardly to form an angle of about 45.degree. with the plate member, and then pressing the free edge downward into contact with the plate member while maintaining a substantially constant curvature of the bend region to produce a beaded edge.

    摘要: The present invention provides an earthquake resistant multi-story building which is characterized by having an energy concentration story. The energy concentration story has an elasto-plastic force-displacement relationship regarding horizontal force and displacement. The force-displacement relationship is characterized in that: (a) stiffness in elastic range (F.sub.y /d.sub.y) is generally equal to an optimal stiffness of the same story according to an elastic design concept; (b) the yield strength F.sub.y is generally less than 80% of an optimum yield strength; (c) stiffness in plastic range is positive and generally less than about a half of the stiffness in the elastic range; and (d) ultimate displacement is generally at least twice as large as the yield displacement. The energy concentration story is capable of entering into the plastic range while other stories are in the elastic range, and absorbing vibration energy by plastic deformations thereof so as to decrease deformations of other stories when a large external force is exerted to the building.

    摘要: Two or more processors with differing address space sizes are used in a multi-processor system. A portion of the memory means accessible by the first processor with a larger address space size is also accessible by the second processor for elevating a utilization efficiency of the memory capacity. A window for the memory space of the second processor is provided in the address space of the first processor. The memory devices controlled by the second processor are controlled through this window by the first processor as well for elevating the utilization efficiency of the memory devices.

    摘要: Automatic electrode shaping apparatus comprising a grinding tool adapted to come in contact with the points of electrode tips attached to the tips of arms of a welding machine for grinding said points, a judging device for judging the shaping condition of said points of the electrode tips, and a tip holding mechanism for holding the electrode tips with the grinding tool coming in contact with the electrode tips, the grinding tool and the judging device being movable with respect to the electrode tips and alternatively located in the position opposite to the electrode tips.According to the automatic electrode shaping apparatus, the electrode tips are held by the tip holding mechanism, and ground and shaped with the grinding tool in a stable manner. After the electrode tips have been shaped, the shaping condition of the electrode tips can be judged whether it is good or bad, without moving the electrode tips.
