Abstract: A backrest of chair in which the lower part of a back frame can be concealed neatly by a stretching material. In the backrest device of a chair where a bag like stretching material (12) knitted or woven in the shape of mesh and opening downward is stretched across a back frame (11) formed by coupling the upper ends of right and left side frames (14a) directing the vertical direction by an upper frame (14b) directing the right and left direction, and coupling the lower ends of both the side frames (14a) by a lower frame (14c) which can be fixed to a backrest supporting rod (8) erected from the upper rear of the seat body of the chair, upper portion of the stretching material (12) is made air permeable, and at least a part at the lower portion of the stretching material (12) covering the lower frame (14c) is made non-translucent.

Abstract: A chair in which a backrest can be largely tilted rearward within a small rotation angle range without increasing the heights of a leg body and a seat body. The leg body (1) includes a pair of left and right side-legs (9) of angular shape in side view, each having a front leg (9a) tilting forward and downward and a rear leg (9b) tilting backward and downward. The lower end of a backrest support frame (3) is so pivotally mounted on the leg body (1) at an appropriate position under the seat body (2) as to be capable of tilting rearward between the left and right side-legs (9).

Abstract: A process for preparing coloring caramel from a pre-gelatinized starch or dextrin. The process comprises preparing a pre-gelatinized starch or dextrin having a specified moisture content and having a specified acidic pH value and extruding it at an elevated temperature and pressure condition effective to caramelize it.The extruded caramel product may be pulverized to yield a powdered caramel.
