摘要： This latent heat storage body is provided with: a latent heat storage material; and a temperature-sensitive material exhibiting different functions at a temperature equal to or higher than a specific temperature and at a temperature lower than the specific temperature, in which a phase change temperature is changed by using the function of the temperature-sensitive material according to ambient temperature. This latent heat storage body is characterized in that: the phase change temperature is set, by the function of the temperature-sensitive material when the ambient temperature is lower than the specific temperature, to one among a low temperature setting and a high temperature setting having a higher temperature than the low temperature setting; and the phase change temperature is set to the other setting among the low temperature setting and the high temperature setting by the function of the temperature-sensitive material when the ambient temperature is equal to or higher than the specific temperature.

摘要： A multistage prism window includes first and second transparent plate materials, a first prism, a reflection member, a second prism, and a heat absorption member. The first prism collects, onto the reflection member, light whose angle with respect to a normal line of the first and second transparent plate materials is equal to or greater than a first predetermined angle and transmits light whose angle with respect thereto is smaller than the first predetermined angle. The second prism collects, onto the heat absorption member, light whose angle with respect to the normal line is smaller than the first predetermined angle and equal to or greater than a second predetermined angle and transmits light whose angle with respect thereto is smaller than the second predetermined angle.

摘要： A structural body includes a refrigerant between a first plate and a second plate. A circulation structural part between the first and second plates includes a reservoir portion provided on a first plate side. In the circulation structural part, the refrigerant from the reservoir portion which has evaporated due to heat of the first plate side reaches a second plate side, condenses on the second plate side and is returned to the reservoir portion again. A temperature sensitive mechanism is in a first state when a temperature of the first plate side is equal to or higher than a predetermined temperature to allow refrigerant circulation, and is in a second state different from the first state when the temperature is lower than the predetermined temperature to prohibit the refrigerant circulation.

摘要： A structure includes: a heat insulating layer; an evaporator provided on one surface side of the heat insulating layer; a condenser provided on the other surface side of the heat insulating layer; a vapor flow path for guiding refrigerant vapor generated as a result of evaporation at the evaporator to the condenser; and a liquid refrigerant flow path for guiding a liquid refrigerant generated as a result of condensation at the condenser to the evaporator, in which the evaporator has a wick layer for evaporating the refrigerant stored on a lower portion side with heat from one surface side of the evaporator while suctioning up the refrigerant by capillarity and holding the refrigerant, and the evaporator and the condenser are installed so as to overlap by ½ or more in the direction in which the wick layer suctions up the refrigerant.

摘要： A ceiling illumination window is provided with a transparent prism, and a reflecting member provided on a second edge of the transparent prism. Further, the transparent prism is installed in such a way as to enable light incident thereon at an angle, relative to a normal line to first and second transparent plates, that is at least equal to a prescribed angle to be reflected at a third edge using a critical angle. In addition, when light is incident at an angle at least equal to the prescribed angle relative to the normal line, the transparent prism emits the light toward an indoor ceiling side using at least two types of optical path having different numbers of reflections, using reflection at least one of the transparent prism surface and the reflecting member, and when light is incident at an angle less than the prescribed angle, the transparent prism allows the light to be transmitted through the third edge.

摘要： Plate glasses of the same material are stacked each other to form a hollow portion between the plate glasses. The stacked plate glasses are heated to a temperature which is a softening point thereof or below and is a temperature or above at which the material can be diffusion-bonded at a predetermined pressure or higher. The heated and stacked plate glasses are pressed to a predetermined pressure or higher using a die. Together with or subsequent to the pressing, a gas pressure is applied into the hollow portion by feeding gas into the hollow portion. Next, the stacked plate glasses, in which the gas pressure is applied to the hollow portion, are cooled to the strain point while being held with the die.

摘要： A dehumidification structure includes: a moisture absorbent which has temperature sensitivity for exhibiting hydrophobicity and releasing water at a temperature equal to or higher than a predetermined temperature and for exhibiting hydrophilicity and absorbing water at a temperature lower than the predetermined temperature; a moisture absorbent chamber in which the moisture absorbent is disposed; and a water draining mechanism configured to drain water released from the moisture absorbent and accumulated in the moisture absorbent chamber. The moisture absorbent is provided to allow reception of solar heat or heat from a heating body that is heated by sunlight. The water draining mechanism is configured to drain the water using weight of the water when an amount of water released by the moisture absorbent and accumulated in the moisture absorbent chamber reaches at least a predetermined amount.

摘要： An outer wall material includes a first transparent member integrally or separately including a transparent plate material and a prism portion; and a reflection member provided on a second side of the prism portion of the first transparent member. The prism portion causes the reflection member to collect light whose angle with respect to a normal line of the plate material is equal to or greater than a predetermined angle and to retro-reflect the collected light, and transmits light whose angle with respect to the normal line of the plate material is less than the predetermined angle.
