Abstract: A process for producing a sheet for sustained release of a volatile drug, characterized by dissolving a resin serving as an adhesive in a volatile drug and using the resultant solution as a coating fluid to bond a film permeable to the volatile drug to another film permeable or impermeable to the volatile drug. No organic solvent or peeling film for process is used, accordingly, unlike the so far known process. Consequently, it is not necessary to provide the drying step for removing an organic solvent as well as any thermal energy. As a result, the number of production steps can be reduced considerably. In addition, since the volatile drug is homogeneously diluted in the adhesive, the volatile drug can be incorporated accurately and evenly even in an amount as small as 1 g/m2 or less. According to the process of the invention, a thinner layer containing a volatile drug can be formed.

Abstract: A chair (10) having adjustable height includes a seat (11) and a number of leg members (12). An adjusting mechanism (30) includes an insert sleeve (40) received within a hollow area (31) of a leg member (12). The insert sleeve (40) has an internal thread (52) which threadably receives a leg extension (60) having an external thread (61). Rotation of the leg extension (60) within the sleeve (40) adjusts the length of the leg member (12).

Abstract: A container (10) includes a cover (12) pivotally attached to a base portion (11) by a hinge assembly (24). The hinge assembly (24) includes a pin (28) carried by the base portion (11) and received through an opening (33) in a knuckle (32) carried by the cover (12). The knuckle (32) is rotated on the pin (28) such that when the cover (12) is on the base portion (11), the opening (33) faces generally downwardly, and when the cover (12) is rotated approximately 180 degrees, the opening (33) faces generally upwardly. The hinge assembly (24) also includes spaced lugs (34) carried by the knuckle (32) and spaced resilient stop members (30) carried by the base portion (11).
