Abstract: The wall serves for separating the inside of a building from the outside. According to a first aspect, the wall has a water vapor diffusion resistance of at most 20 meters, wherein the heat transfer coefficient amounts to at most 1.5 W/(m2·K), and the moisture storage capacity amounts to at least 2 kg/m2. According to a second aspect, the wall has a bearing layer (10) as well as an outer layer (9) and an inner layer (11), which include moisture-buffering materials.

Abstract: A music stand device is disclosed. A score panel (SP) is aligned to a top plate (TP) when it is laid down. Position accuracy of the SP relative to the TP is enhanced. An accommodating member and a guide member are installed to a lower surface of the TP. When another end of a supporting member is rotatably connected to a bottom surface of the accommodating member, it is disposed at a position lower than the lower surface of the TP. A rectangular body-side guide slot is disposed on the lower surface of the TP. A guiding-side guide slot is disposed on the guide member. The two slots are disposed at a position lower than an upper surface of the TP. When a shaft-like member slides in the two slots to lay down the SP, the SP is disposed in an opening of the TP to align with the TP.
