A method and system for producing poly(lactic acid) enable trapping and recovering of lactide vapor discharged from a reaction vessel without requiring a solvent or the like. In the method and system, lactide vapor is discharged from a polymerization reaction vessel in which poly(lactic acid) is produced by ring-opening polymerization, and trapped by solidification. The solidified lactide is liquefied by heat. Lactide can be recovered more easily and assuredly.

A cam mechanism for a lens barrel includes an annular member which is linearly guided along an optical axis, and having a cam follower on an outer peripheral surface; a cam ring having a cam groove on an inner peripheral surface including a photographing section and an accommodation section, the cam follower being engaged in the cam groove; and a biasing device for biasing the annular member forward to normally press the cam follower against a front cam surface in the cam groove. A rear end portion of the cam groove is open at a rear end surface of the cam ring to serve as the accommodation section, and the cam follower is disengageable from the front cam surface in the cam groove against a biasing force of the biasing device when the cam follower is engaged in the accommodation section.

On the porous surface of valve metal, an anodically-oxide film of the valve metal is formed and, after that, a conducting polymer layer is formed on the oxide film. Subsequently, the conducting polymer layer is dried and, after that, the anodically-oxide film of the valve metal is reformed. As mentioned above, the water content in the conducting polymer layer is reduced by drying and, after that, the anodically-oxide film of the valve metal is reformed, so that a peroxidative reaction with moisture in the conducting polymer layer in the reformation can be suppressed and an excessive insulation of the conducting polymer layer can be prevented. Consequently, there can be obtained a solid electrolytic capacitor in which an increase in equivalent series resistance is prevented and the conducting polymer layer is made of a solid electrolyte.
