    摘要: To provide a double-deck elevator characterized by the fact that by increasing the story height adjustment range in the direction in which the two cars approach each other, it is possible to increase the degree of building design freedom. Two up/down cars (6), (7) arranged in outer frame (5) are connected with each other by means of pantographic mechanisms (11) that can effect an expansion and contraction operation, and the two cars (6), (7) are driven to move towards each other or away from each other by means of pantographic mechanisms (11). The pantographic mechanisms (11) are arranged in the spaces between vertical beams (5a) and the two cars (6), (7) and each has a pivot point at the longitudinal central portion of vertical beams (5a) extending vertically in outer frame (5). Due to the pantographic mechanisms (11), the story height adjustment range in the direction in which the two cars (6), (7) approach each other is not restricted.

    摘要: The welding quality of materials sandwiched between and welded by two electrodes is monitored by a welder monitor, which includes a detecting section for detecting a welding current and a welding voltage, an operation section for numerically analyzing, based on a heat conduction model, a temperature distribution of the two electrodes and that of the materials using the detected welding current and welding voltage, to thereby estimate a nugget diameter during welding, a reference diameter setting section for setting a reference nugget diameter, and a diameter comparing section for comparing the nugget diameter during welding with the reference nugget diameter, to thereby compute a time at which the nugget diameter exceeds the reference nugget diameter. The welder monitor also includes a reference time setting section for setting a reference time shorter than a given time until which welding of intended materials is not terminated, a time comparing section for comparing a nugget formation time, at which the nugget diameter during welding exceeds the reference nugget diameter, with the reference time set by the reference time setting section, and an output section for outputting a comparison result from the time comparing section. When the nugget formation time is shorter than the reference time, the nugget formation time is outputted to the output section.

    摘要: A device for connecting a catheter to an injection tube, which is provided with an elastic tube into which an open end of the tubular catheter having electrodes disposed at the closed end thereof and also having conductive wires connected to said electrodes and taken out at the open end thereof and an open end of the injection tube having a mechanism for fluid injection at the other end thereof are inserted so that both open ends are connected end-to-end and the conductive wires are taken out through a gap between the elastic tube and the injection tube; and a sealing agent to cover respective surfaces of the catheter, injection tube, and elastic tube which surfaces are coated with an adhesive. The catheter, injection tube, and elastic tube, when coated with an adhesive of high viscosity, are compatible with the hard sealing agent lying thereabove. A casing consisting of half members encloses the sealing agent and the casing increases the strength of the device, whereby the device is prevented from being deformed and prevented from causing leakage of fluid through the gap even when subjected to external force. The device has improved resistance to external pressure. In addition, connection of the conductive wires between the electrodes and the terminals arranged on the side of the casing serves to tightly fix the wires in the sealing agent packed in the case and causes no breakage of the wires, whereby the wires are connected to the external parts through the terminals to thereby provide a device with improved reliability.
