Abstract: PROBLEM TO BE SOLVED: To heighten the water absorption speed, make drying easy, and lower the load at the time of pulverization by producing water absorptive resin composition from foamed water absorptive resin and fluoro-type surfactant. SOLUTION: A water absorptive resin composition with high water absorption speed to be used for sanitary material fields, agricultural and horticultural fields is produced from foamed water absorptive resin and a fluoro-type surfactant and the foamed water absorptive resin is produced by polymerizing a mixture of a water soluble unsaturated monomer unit and a cross-linking monomer unit in a state wherein bubbles of an inert gas are dispersed or adding a foaming agent after polymerization. In this case, the quantity of the fluoro- type surfactant is set to be within a range from 0.0001-30wt.% to 100 pts.wt. of the water absorptive resin and as the water absorptive resin, resin having 0.02-1.0m<2> /g specific surface area is used.  Moreover, powder materials having 100-1,000μm average particle diameter are examples for the water absorptive resin composition and it is preferable for the water absorptive resin composition to be treated with a surface cross-linking agent.

Abstract: PURPOSE:To tighten the safety of supervising passengers by providing a means, which detects a vehicle to advance running in an abnormal speed adjacent to the side of a platform, and, in the time of detecting the vehicle, generating an alarm to the passengers present on the platform in its position to the vehicle passing. CONSTITUTION:A passenger, being present on a platform in a position to a vehicle passing, is detected by passenger detectors 21-23, while a speed of the vehicle 1, advancing adjacent to a side of the platform, is detected by train detectors 11-13 and a speed arithmetic circuit. Here the vehicle speed, when it is detected to be in an abnormal speed increasing to the reference speed or more, causes an abnormal-speed detector to be driven. In this case, when the passenger is detected to be present on the platform in a position to the vehicle passing by the passenger detectors 21-23, an alarm is generated from alarm devices 21, 32. Thus enabling the safety of passengers on the platform to be surely and promptly ensured with no necessity for performing work through labor, a safety supervisory device can be easily applied even to a one- man train.
