Abstract: A determination device includes an irradiator, an extractor, an imager, and a determiner, The irradiator irradiates an object including a food or a plant with a light. The extractor extracts a predetermined fluorescence emission having a predetermined wavelength out of fluorescence emissions generated from a surface of the object irradiated with the light. The imager captures a fluorescence image indicating the predetermined fluorescence emission. The determiner determines a state of the object based on an index indicating a fluorescence intensity of the fluorescence image.

Abstract: An aluminum oxide article containing at least aluminum atoms and oxygen atoms is described. When observed under a transmission electron microscope, a cross section of the aluminum oxide article contains crystallized parts, in which a crystal lattice image is recognizable, and a non-crystallized part, in which no crystal lattice image is recognizable, and has an island-and-sea structure consisting of isolated parts containing the crystallized parts and the continuous non-crystallized part. The isolated parts correspond to island parts in the island-and-sea structure, the continuous non-crystallized part corresponds to a sea part, and a plurality of the island parts are uniformly distributed in the sea part. An aluminum oxide for improving the battery performance of a lithium ion secondary battery, the scratch resistance and hardness of a cured film, and the gas barrier properties of a gas barrier film is provided.

Abstract: A sewing mechanism is provided with: a post bed and sewing needles, wherein an article to be sewn is interposed between the post bed and the sewing needles. When the post bed comes closer to the article to be sewn than that in the previous sewing by at least a predetermined distance, in other words, when a separation distance between the article to be sewn and the post bed becomes less than that in the previous sewing by at least a predetermined distance, a thread pulling mechanism pulls threads hooked in needle holes of the sewing needles in a direction away from the post bed.

Abstract: Provided are an injection mold and an injection molding method by which a boundary line between a first material and a second material curved so as to be sharply bent like a round chamfered shape can be formed reliably in a desired position, and a molded article molded using the injection mold and the injection molding method. The sum of a length w of an inclined-part forming part 51a and a length y of a thinned-part forming part 51b in a width direction of a linear part or a width direction of a curved part is at least equal to a prescribed value, and the thinned-part forming part 51b forming the curved part has a second length y longer than a first length in the width direction of the curved part.

Abstract: Provided is a solid polymethylaluminoxane composition which has higher activity when being used as a co-catalyst in olefin polymerization. The solid polymethylaluminoxane composition contains polymethylaluminoxane, trimethylaluminum, and Al2O3, wherein: (i) the aluminum content is in a range of 36-43 mass %; and (ii) the Al2O3 content is in a range of 0.001-10 mol % represented in terms of aluminum.
