Abstract: A partition has an air blowing function of blowing air to a predetermined region. The partition includes a casing, a blower mechanism arranged in the casing, and a blow-out port formed in the casing. On a virtual plane facing the blow-out port and having a wind velocity of 0.2 m/s or more, an airflow with an average momentum per unit area from 0.05 kg/ms2 to 0.75 kg/ms2 is generated.

Abstract: A determination section of a sleep control apparatus determines an awakening point based on target data. The target data is time-series data of biological information of a target person in a target period. The target period is a period between wakefulness to failing asleep of the target person, or a period from the wakefulness of the target person to a time point at which a predetermined time has passed since the target person fell asleep. The controller controls a target device so that the target device stimulates the target person to wake up at the awakening point.

Abstract: An air filter medium includes a glass filter medium layer that includes a glass fiber. The glass filter medium layer has a protruding portion. The protruding portion undergoes a change in protrusion height of 70% or less when left to stand at an atmospheric temperature of 100° C. for one hour.

Abstract: Provided are a filter medium for an air filter capable of having extended life even when composed of embossable material. The filter medium (1) has a tensile elongation of 10% or greater, and includes a main collection layer (30) having a filing rate of 5% to 15%, a thickness of 0.35 mm to 0.70 mm, and a peak in a fiber diameter distribution at less than 1.0 ?m and a peak at 1.0 ?m or greater. An average fiber diameter of small fiber diameters of less than 1.0 ?m is from 0.1 ?m to less than 0.8 ?m, and an average fiber diameter of large fiber diameters of 1.0 ?m or greater is from 1.2 ?m to less than 3.0 ?m. A volume ratio of the fibers having the small fiber diameter to the fibers having the large fiber diameter is from 30:70 to 80:20.
