Abstract: Liquid hydrogen is produced while reducing emission of carbon dioxide to the atmosphere. Provided is a liquid hydrogen production device including: a carbon dioxide cycle plant (2), which includes a turbine (23) using a carbon dioxide fluid as a driving fluid, and is configured to drive the turbine (23) to generate motive power with use of a carbon dioxide cycle in which the carbon dioxide fluid discharged from the turbine (23) is increased in pressure and heated and is then re-supplied to the turbine (23); and a liquefaction plant (4) configured to cool gaseous hydrogen by heat exchange with a refrigerant, to obtain liquid hydrogen. The motive power generated by driving of the turbine (23) is used as motive power to be consumed in the liquefaction plant (4).

Abstract: A transparent resin molded product and a mold for molding the product are provided in which occurrence of silver streak in the resin molded product is prevented. The resin molded product includes a design portion and a non-design portion, at least a part of the design portion is molded by transparent resin, and a gate trace (a gate arrangement position during the resin molding) is disposed in the non-design portion (runner portion). A foreign matter restraining portion for restraining foreign matters and bubbles contained in the transparent resin is disposed in the vicinity of the gate trace of the non-design portion. The foreign matters and bubbles are restrained by the foreign matter restraining portion and are prevented from flowing to the design portion, and therefore the occurrence of silver streak on the design portion can be prevented.

Abstract: A resin-molded component includes a first molding part, and a second molding part. A portion of the first molding part and a portion of the second molding part are laminated in a direction of connecting an outer surface and an inner surface of the resin-molded component to provide a laminated portion. A portion of the second molding part is provided as an exposed portion. Each of portions of the laminated portion is located at least on opposite sides across the exposed portion. A one-side surface of the exposed portion in the laminating direction of the laminated portion is configured as a portion of the outer surface and the other-side surface thereof is configured as a portion of the inner surface.

Abstract: A printing paper information reading apparatus for accurately detecting cut marks 3a and reading information formed on printing paper 3. The apparatus includes a first mark detector 29a for detecting the cut marks 3a formed for frame images printed on the printing paper 3, respectively, a second mark detector 29b for detecting information marks 3c formed in the printing paper 3 in a corresponding relationship to the cut marks 3a, and a printing paper information generator 5g for generating printing paper information by evaluating results of detection of the information marks 3c by the second mark detector 29 in synchronism with detection of the cut marks 3a by the first mark detector 29a.
