Abstract: An electrical device for a human-powered vehicle comprises a main body, an item storage, and an actuator. The main body is configured to be coupled to a vehicle body of the human-powered vehicle. The item storage is at least partially provided to the main body so as to store an item. The item is free from function of the electrical device or non-operational with respect to the electrical device in a state where the item is at least partially arranged in the item storage. The actuator is coupled to the main body.

Abstract: An upright piano includes an internal space enclosed by a case including an upper front board disposed above a key bed and a lower front board disposed below the key bed, and a resonance tube in which a hollow region having an opening is formed and that is disposed in the internal space, in which the opening is disposed at the left end of the lower end of the upper front board or the upper end of the lower front board, or at the right end of the lower end of the upper front board or the upper end of the lower front board.

Abstract: An automatic spraying apparatus comprising storage tanks each storing therein each one of at least two liquid components which are mixed to produce hard urethane foam, a pump for feeding said each liquid component under pressure, a spray gun for mixing said liquid components fed from said pumps and spraying the mixture, a mechanism for displacing said spray gun in a plane spaced apart from and substantially in parallel with a surface to be sprayed, and a control unit for controlling the displacement of said spray gun so as to follow a predetermined path.

Abstract: A polyisocyanate foam having isotropic cells is manufactured by a foaming operation in an apparatus comprising a mold composed of side walls capable of extending and returning, or folding and unfolding, in directions perpendicular to the free rising direction. Mold extending means are provided to spread out the side walls of the mold perpendicular to the free rising direction. While the foamable composition is in a creamy state, it is allowed to rise freely in one direction (the free rising direction), while the side walls of the mold are in their folded condition, until a height detecting means is actuated.

Abstract: The invention relates to liquefied gas containers, particularly liquefied gas ships, having a foamed plastics insulation system. The invention provides an arrangement for the corners/top edge of the insulation in which the foam plastic insulation material for each wall area is foamed onto a rigid outer support shell so that it stops just short of the corners/top edge of said shell. The edges of the foam are anchored by reinforcement mesh or the like bonded to the inner face of the foam, the mesh extending over the edges of the foam and being bonded by adhesive into the shell corners. In the case of the corners, a coving is laid across each corner and is bonded to the inner faces of the adjacent wall areas. Further foamed insulation is then built up behind the coving to the required thickness.
