  • Patent number: 12492330
    Abstract: A latent heat storage gypsum plate includes: a gypsum plate having a first main face and a second main face located on an opposite side of the gypsum plate from the first main face; and a latent heat storage layer disposed over at least part of the first main face of the gypsum plate and including a latent heat storage material and a binder. A heat storage capacity of the latent heat storage gypsum plate is 260 KJ/m2 or more, the heat storage capacity being measured in a measurement temperature range of from 15° C. through 35° C. through heat storage capacity measurement specified in ASTM C 1784. The latent heat storage gypsum plate exhibits heat generation property grade 1 as evaluated by a heat generation property test specified in JIS A 6901 (2014), with the face in which the latent heat storage layer is disposed being set as a back face.

  • Patent number: 12312809
    Abstract: The present invention is to provide a gypsum-based load-bearing board for wood structural load-bearing walls which is capable of increasing the co-efficient of effective wall length without additionally using reinforcement materials or stiffening materials, and without increasing the specific gravity and/or the thickness of the gypsum-based load-bearing board. The gypsum-based load-bearing board for wood structural load-bearing walls includes a main member or a core member formed from a board-shaped hardened gypsum containing an inorganic fiber and an organic-based strength enhancer that exert a lateral nail resistance of 500 N or more, and a paper covering at least front and back sides of the main member or the core member to constitute the load-bearing board.

  • Patent number: 11306981
    Abstract: A heat exchanger (1) includes a heat exchanging body (20) disposed within an outer box (10). A supply pipe (21) and a discharge pipe (22) in fluid communication with the heat exchanging body (20) respectively extend through first and second insertion holes (31, 32) in the outer box (10). Elastic seal members (40; 240) are respectively provided around the supply pipe (21) and the discharge pipe (22) and between a first sidewall (11) of the outer box (10) and the heat exchanging body (20). At least one biasing member (50; 250) exerts a lateral biasing force (F1; F2) on the elastic seal members (40; 240), thereby maintaining the elastic seal members (40; 240) in a state of compressive deformation and contacting the outer box (10) and the heat exchanging body (20) in an air-tight manner to block potential leakage paths (LP1; LP2) via the insertion holes (31, 32).

  • Patent number: 11131512
    Abstract: The exhaust duct includes an exhaust collecting portion connected a heat exchanger and an exhaust guiding portion communicating with the exhaust collecting portion and extended upward in a state close to a side of a cylindrical body of the heat exchanger. The exhaust collecting portion includes a connection opening constituting an inner peripheral wall, into which a cylindrical outlet side connection portion at the lower end of the heat exchanger is fitted, and a groove provided on an outer peripheral side than the inner peripheral wall of the connection opening. The packing includes a seal portion sandwiched in a compressed state between the inner peripheral wall of the connection opening in the exhaust collecting portion and an outer peripheral wall of the cylindrical outlet side connection portion in the heat exchanger to constitute a seal and an anchor portion inserted into the groove of the exhaust collecting portion.
