Abstract: Provided is a conveyance seat capable of reducing the number of components and reducing swing of a seat cushion while a vehicle is travelling. The conveyance seat is a seat including a cushion lock apparatus turnably coupling a seat cushion to a seat back and configured switchable between a seatable state and a housing state. The cushion lock apparatus includes a lock member attached to a seat cushion side, a lock target member attached to a seat back side and engaging with the lock member to lock turning motion of the seat cushion, and a position holding member holding at least one of the positions of the lock member and the lock target member to hold a state in which a clearance is, in the seatable state, formed between an engagement portion provided at the lock member and an engagement target portion provided at the lock target member.

Abstract: A biodegradable nonwoven fabric and molded vessel suitable to throwaway use such as in domestic, wrapping, agricultural, gardening, and civil engineering field. A web of cellulose-based fibers are combined with chitosan salt and an interfiber binder comprising a combination of chitosan salt and fine cellulose, or by combined use of the interfiber binder and physical combining techniques. They are naturally decomposed by microorganisms in the soil and can dissolve the polution problems.

Abstract: A biodegradable film or the like shaped article is formed from a composition including 100 parts by weight of cellulose fibers having a length of 3 mm or less and a diameter of 50 .mu.m or less, 10-600 parts by weight of a thermoplastic resin and 2-100 parts by weight of chitosan. A mixture containing (a) an aqueous solution of an acid salt of chitosan, (b) an aqueous dispersion or solution of a thermoplastic resin and (c) fine cellulose fibers is dried and shaped to obtain such a biodegradable shaped article.

Abstract: A biodegradable sheet is produced from an aqueous dispersion containing finely cut cellulose fibers and chitosan. The dispersion is maintained at a temperature T.sub.1 .degree.C. which is within the following range:t.ltoreq.T.sub.1 .ltoreq.t+30wherein t is the boiling point (.degree.C.) of water at a given reduced pressure and is continuously introduced into a defoaming zone maintained at the given reduced pressure and at a temperature within the same range as that of T.sub.1. In the defoaming zone, the dispersion is formed into a downwardly flowing laminar flow so that air entrapped therein is effectively removed therefrom. The defoamed dispersion is then passed through a die and is molded into a sheet which is subsequently dried.
