Abstract: Provided is a eutectic ceramic fiber which has high tensile strength and whose microstructure is not easily coarsened even in a case where the eutectic ceramic fiber is exposed to high temperature air for a long time. The eutectic ceramic fiber includes a Y3Al5O12 matrix and rod-shaped Y2O3-containing cubic crystals of ZrO2 present in such a manner as to be dispersed in the Y3Al5O12 matrix. The Y3Al5O12 matrix is a continuous phase, and the rod-shaped Y2O3-containing cubic crystals of ZrO2 are oriented in a longitudinal direction of the eutectic ceramic fiber.

Abstract: A partition includes a first structure, a deformable partitioning portion connected to the first structure, and an air-environment adjusting portion disposed at at least one of the first structure and the deformable partitioning portion. The deformable partitioning portion has a first end portion on a side connected to the first structure and a second end portion on a distal side from the first end portion. The deformable partitioning portion partitions a predetermined space with respect to an adjacent space. The air-environment adjusting portion includes at least one of a cooling portion configured to cool air, a heating portion configured to heat air, and an airflow generating portion configured to generate an airflow.

Abstract: A projector that projects an image on a screen includes a projection port for projecting the image in a direction tilting to the lower side with respect to the horizontal direction, a housing, and an exhaust panel provided in an exhaust port formed in the housing and configured to restrict a moving direction of the air discharged through the exhaust port. The exhaust port is formed on a right side surface toward a projecting direction of the image in the housing. The exhaust panel forms a channel that connects the inner side and the outer side of the housing. The channel has a tilt coming closer to a direction vertically opposite to the projecting direction of the image and closer to the screen from the inner side toward the outer side.

Abstract: A biological-information detecting device includes a case section worn on a subject, a detection window of a detector configured to detect biological information of the subject being provided on a first surface on the subject side of the case section, a band section attached to the case section, and a pad section provided around the detection window on the first surface of the case section. An air entry path for the air to enter the detection window is provided in the pad section.

Abstract: A biological information detection device includes a case that is provided with a sensor that detects biological information about a subject, a band that secures the case on the subject, and an adjustment mechanism that pulls the band in a first direction when a rotary member that is supported by the case has been rotated, the first direction being a direction in which the side of the case that is situated opposite to the subject comes in contact with the subject.
