摘要： PROBLEM TO BE SOLVED: To regulate the moisture content of a soil layer in such a manner that NO may be effectively removed. SOLUTION: Polluted air is supplied by a blower 8 into the soil layer 6 in a vessel 4. This polluted air passes the inside of the soil layer 6. The polluted air is thus purified by the effect of the microorganisms, etc., included in the soil layer 6. A controller 14 outputs a signal to a solenoid valve 42 to open the valve when the moisture content of the soil layer 6 measured by a pF meter 10 is about 3.0 in pF. The water stored in a feed water tank 32 is then supplied through a tubular body 50 to water feed pipes 40 and are ejected out of the many holes formed at the water feed pipes 40. When the moisture content attains about 2.5 in pH, the solenoid valve 43 is closed to stop the water feed. The moisture content of the soil layer 6 is kept at about 2.5 to 3.0 in pF by such regulation by the controller 14. When the moisture content of the soil layer is at this level, the NO is most effectively removed.

摘要： PURPOSE:To improve fluttering hcaracteristics, by making use of boss metal fittings constituted by enclosing an elastic material, in a method of manufacturing a core material of a steering wheel made of FRP by winding round a resin impregnated long fiber. CONSTITUTION:Boss metal fittings 10 are constituted of two members of an inside member 11 and outside member 12, a recessed part and protruding part for fitting confronting surface of both the members each other are provided and an elastic material 14 such as rubber is enclosed into a gap part between both the recessed part and protruding part. A core material of a steering wheel is molded by winding a resin impregnated long fiber round a forming jig of a ring part not illustrated herein and the boss metal fittings 10 situated at the shaft center of the said jig. When external force to be applied to the steering wheel is of low torque, fluttering characteristics are improved as an elastic member absorbs an oscilation in a peripheral direction. When the torque becomes high, both the members are fitted at the recessed part and protruding part each other and the torque is transmitted to a shaft.

摘要： PURPOSE:To prevent the mounting failure of a pad from occurring, improve the operability and decorativeness and at the same time improve the formability for covering core materials by a method wherein the so-called marked-off portion of each spoke part is covered with a precisely molded synthetic resin cover. CONSTITUTION:In a first process, a steering wheel core material 10 is formed by laminatedly taking up a resin-impregnated continuous long fiber with a reeling jig 1. In a second process, the uncured core material is mounted on a marked-off part forming jig 15. The jigs 15 are positioned and fixed so as to precisely form so-called marked-off parts or portions, each of which corresponds to the peripheral edge part of a pad to be attached on a steering wheel in the form of a finished product and is covered with urethane, of spoke parts. Then, the core materials are cured. After the complete curing of the core materials, the marked-off part forming jigs are removed. In a third process, for example, molding tools for covering urethane are installed onto the molded steering wheel core materials so as to pour urethane stock liquid in the tools in order to form urethane coverings onto the cured core materials. At this time, the leakage of the urethane stock liquid is suppressed and consequently urethane-covered marked-off parts having both accurate dimensions and precise shapes are molded.
