Abstract: A load sensor includes a core having a hollow part provided therein and containing magnetic material and a coil attached to the core. A magnetic path along which a magnetic flux generated by a current flowing in the coil is formed along a circumference direction of the hollow part. The core has a load-receiving portion that receives a load at a surface of the core located in a crossing direction crossing a plane along which the magnetic path is formed.

Abstract: A seat belt drawing angle adjusting device provided on the upper end part of a seat back, comprising a housing, a seat belt retractor supported within the housing, a seat belt guide member rotatably supported in the housing and a lock mechanism for locking and unlocking the guide member. The guide member has, formed therein, a slit through which a seat belt passes from the retractor to the outside, and is so arranged as to be vertically movable, thereby allowing vertical displacement of the slit. Hence, the seat belt can be adjusted at lower or higher level in relation to its drawing point.

Abstract: A method for manufacturing a seat for use in an automobile, airplane and the like is disclosed which comprises the steps: knitting at least two kinds of synthetic fibers respectively having different average heat setting temperatures to form a bag-shaped trim cover assembly of a size suitable for covering a pad of foam material; covering the foam pad with the thus-formed trim cover assembly; and then heat-setting both the trim cover assembly and the pad at temperatures necessary for the trim cover assembly to shrink sufficiently so that the trim cover assembly can be brought into close contact with the surface of the pad.

Abstract: An aqueous dispersion of partially neutralized ethylene/.alpha.,.beta.-ethylenically unsaturated carboxylic acid copolymer having a specific composition distribution of the acidic units is found to have an excellent film-forming property and suitable for coating of various substrates. Articles coated with said aqueous dispersion are improved in various properties such as heat-sealability, oil resistance, water resistance, adhesiveness and so on.
