Title: Method for joining metallic sheet to suspender
Inventor: HIDA HARUO
IPC: E04D3/369
Filed: 1988-11-10
Abstract: PURPOSE:To continuously seam-weld a three-ply part and a two-ply part of metallic sheets by bending the ends of the metallic sheets to abut these on each other and subjecting the three-ply part wherein a tabular suspender is sandwiched to seam welding by using electrode rolls having thick walls and the peripheral contact surfaces with a rounded shape. CONSTITUTION:Stainless steel face materials 13 and 14, and the suspender 11 are pressed between the electrode rolls 8 and electrified. The electrode rolls 8 have 15-30 times thickness as much as stainless steel face material thickness and are made of a discoid Cu alloy with good heat conduction and the peripheral surfaces thereof have the 50-100 times radiuses R as much as stainless steel face material thickness and are rounded and provided with water-cooled jackets 8a. When the wall thickness of the electrode rolls 8 is small, high current is not allowed to flow through the electrode rolls and when the wall thickness is large, heat loss thereof increases. When the radiuses R of the peripheral surfaces are small, dents are too deepened and when the radiuses are large, bearings run short. The high current required for the three-ply part is charged and the three-ply part and the two-ply part are seam-welded continuously.

Title: Particulate monitor for static pressure bearing
Inventor: KASE KATSUSABURO
IPC: F16C32/06
Filed: 1992-10-01
Abstract: PURPOSE:To allow the accumulation of particulates to be monitored by providing a monitor pad almost unloaded and almost of the same constitution as the bearing static pressure pad of a static air pressure bearing device, and diverging air to supply it to the monitor pad. CONSTITUTION:A monitor pad 8 is almost of the same constitution as the bearing static pressure pad 1 of a static pressure bearing device, and a fluid to be supplied to the pad 1 is diverged and supplied to the monitor pad 8. During the monitor period, the particulates included in the fluid or the like are accumulated at the monitor pad 8 under the same condition as the bearing static pressure pad 1. Since the monitor pad 8 is almost unloaded, the accumulation is faster compared to the bearing static pressure pad 1, which results in indicating the future accumulated state of the bearing static pressure pad 1. The degradation progress of the bearing static pressure pad 1 is thereby predicted by examining the accumulated quantity in the monitor pad 8 directly or indirectly on the basis of the flow to the monitor pad 8, and a warning is generated. The maintenance of a static pressure bearing device is thereby simplified.
