Inventor: YO BAIKA
IPC: D04H1/4258
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To obtain a fabric for moisture management without the limitation of denier ratio but having advantages of high wearability and comfortable texture. SOLUTION: This fabric for moisture management comprises a number of first fibers 13 and a number of second fibers 14 and at least the second fibers 14 comprise a configuration for enhancing capillarity therein. Thereby, the second fibers 14 have stronger capillarity. The two fibers are fabricated as a knitted fabric, a woven fabric or a nonwoven fabric in order to form the fabric for absorbing the moisture with the first fibers 13 mainly on one surface of the fabric and the second fibers 14 mainly on another surface of the fabric. Consequently, the moisture absorbed by the first fibers 13 can easily be transferred to the second fibers 14 due to the difference in the capillarity.

Title: Container of nuclear reactor
Inventor: YAMAKI RIKA
IPC: G21D3/08
Filed: 1988-10-07
Abstract: PURPOSE:To reduce hazards of a hydrogen explosion by providing the container with a hydrogen concentration meter, a blower, a hydrogen recombiner and an ignitor, by actuating the ignitor when a rate of change with time of the hydrogen concentration is large enough, and by actuating the blower when the rate is rather small. CONSTITUTION:A hydrogen concentration meter 4 and a calculator 5 of a rate of change with time are arranged in a container 3 of a nuclear reactor. A local high concentration of hydrogen is prevented by actuating the blower 7 when a generated amount of the hydrogen stays within a range of a normal operation. When generation of substantial amount of the hydrogen is predicted, the hydrogen is ignited using the ignitor 8 while an amount of the hydrogen at a ceiling part of the container 3 stays still at a low concentration to flame it before the amount of the hydrogen reaches an explosion limit. In this way, the hydrogen generated in the container 3 is removed while its concentration is rather low. Therefore there is no possibility for the hydrogen concentration to reach the explosion limit and a hazard of hydrogen explosion can be taken away.
