The decorative layer includes a transparent adhesive resin layer (3b), a transparent polyester resin layer (3a) which is the outer surface layer, and an intermediate gradation layer (3c) including a portion of which the thickness gradually varies in the direction of height of the container. The gradation layer is formed of a transparent polyester resin blended with a coloring agent. The thickness of the container body varies in response to a change in the thickness of the gradation layer in a manner such that the thickness of the container body portion which is the total thickness of the thickness of the container body and the thickness of the decorative layer is not varied by the presence of the gradation layer.

Abstract: An intraocular lens insertion device having a configuration in such a manner that, with the displacement of a haptic toward the convex side of an optical portion, which can be deformed in a curved shape, restricted by an engaging part provided to the tip part of a plunger, the haptic is deformed in a curved shape in the direction in which the haptic approaches the optical portion. The configuration allows, when the intraocular lens is pushed out by the plunger, the haptic to enter a gap formed on the concave side of the optical portion which has been deformed in a curved shape.

Microalgae on the bottom surface are used as seed algae. That is, there is provided a method for culturing microalgae which includes: a first culture process of culturing microalgae in a medium within a culture vessel, forming a biofilm on the liquid surface of the medium, and maintaining the microalgae on the bottom surface of the culture vessel; a process of collecting at least a part of the biofilm on the liquid surface formed in the first culture process and leaving at least some microalgae on the bottom surface inside the culture vessel; and a second culture process of culturing the microalgae remaining on the bottom surface within the identical culture vessel, and forming a biofilm on the liquid surface of the medium. In addition, the present invention provides novel microalgae which can form a biofilm on the liquid surface.

Abstract: In a liquid surface-floating culture method in which culturing of microalgae is performed on the liquid surface, there is provided a culture method in which the oil content in microalgae is improved. In addition, there is a provided a method for decreasing the probability of recovery of bottom surface algae. Furthermore, an object of the present invention is to provide a culture method in which the proliferation rate of microalgae is improved. Culturing is performed such that a medium is suctioned from a region, in which there is a small quantity of microalgae between the liquid surface and the bottom surface, is discarded, and is replaced with a medium of which the concentration of a nitrogen compound or a phosphorus compound is lower than that of the above-described medium. In addition, a liquid is added thereto immediately before collecting microalgae on the liquid surface, and the water depth in a culture vessel is made to be deep.

Abstract: There is provided a method of culturing microalgae, including: culturing in a first stage in which microalgae obtained through a purification process are cultured in a culture solution within a first culture container to form a biofilm as a film-like structure or a three-dimensional structure which is formed of the microalgae on a liquid surface of the culture solution; and culturing in a second stage in which microalgae are cultured on a liquid surface using at least a part of the biofilm as a film-like structure or a three-dimensional structure which is formed on the liquid surface of the culture solution, as seed algae.
