Abstract: A package receiving and storage apparatus includes a takeoff and landing section; a package receiving section; a storage section; a retrieval section at which the first package stored in the storage section is retrievable; a transport device configured to transport the package between the package receiving section, the storage section, and the retrieval section; and a gas spray device installed at the package receiving section or in a package transport path extending from the package receiving section to the storage section, and configured to spray a gas onto the first package to remove foreign matter adhering to the first package.

Abstract: A determination method according to an example aspect of the present disclosure includes: acquiring a plurality of captured images of an object successively captured by an image capturing apparatus in a state in which a positional relation between the object and the image capturing apparatus is changing; dividing each of the plurality of captured images that are continuous in time into a plurality of image areas; associating the plurality of divided image areas among the plurality of captured images that are continuous in time; calculating a luminance difference between a maximum luminance value and a minimum luminance value in each of the image areas that have been associated; and determining the type of the paint applied to the object based on changes in the luminance differences in the plurality of image areas associated among the plurality of captured images that are continuous in time.

Abstract: This invention provides a multilayer coating film-forming method which comprises applying a first clear paint onto a coating object, applying onto so formed first clear coating film which is either uncured or cured by heating, a second clear paint such that its heat-cured film thickness falls within a range of 2-15 ?m, and forming the second clear coating film, (a) the first clear paint and second clear paint comprising hydroxyl-containing resin as the base resin and polyisocyanate compound as the crosslinking agent, and (b) when the coating film formed by applying a paint to a cured film thickness of 40 ?m and curing it by heating at 140° C. for 30 minutes is measured of its dynamic viscoelasticity at a frequency of 11 Hz, the first clear paint forming the first clear coating film having a glass transition temperature of lower than 70° C. and tan? (=loss elastic modulus/storage elastic modulus) at 80° C. of less than 0.

Abstract: An absorption refrigerating/heating apparatus in which a refrigerant vapor generated in the evaporator (1) is absorbed to produce absorption heat by the absorbent in an absorber (2). There are first tube for chilled water in the evaporator, a second tube for cooling water in the absorber, a third tube in an indoor unit (15), and a forth tube in a sensible heat exchanger. The first tube and the second tube are respectively connected to the third tube and the fourth tube in a cooling operation, while to the fourth tube and the third tube respectively in a heating operation.

Abstract: A compact plasma cutting apparatus suitable for the thermal cutting of concrete structures includes a sealed housing to which a plasma gas is fed under pressure. A metal strip that serves as an outer hollow electrode is bent such that a widthwise section thereof is in circular form, while a metal rod or tube is continuously inserted through a hollow portion of the thus formed outer electrode, with an insulator located between both electrodes. While gas is passed between the inner and outer electrodes, an arc is produced at open ends of both electrodes to generate a plasma gas, which is in turn blown onto a concrete structure for thermal cutting. The formation of both electrodes is effected depending on consumption of the electrodes, thereby carrying out thermal cutting continuously. A high-efficient yet economical cutting method is achieved using the cutting apparatus.
