摘要： The present invention provides a spiral membrane element suitable for suppressing a decrease in a permeation rate (or a permeation flux) of a permeated fluid from a separation membrane. A spiral membrane element of the present invention includes: a central tube; a membrane leaf that has a separation membrane and a permeation spacer and is wound around the central tube; and a flow passage spacer that is connected to the permeation spacer and is wound around the central tube on a side closer to the central tube than the membrane leaf is. A pressure loss of the flow passage spacer measured by a predetermined test is smaller than a pressure loss of the permeation spacer.

摘要： An optical transmission system converts a first electrical signal into an optical signal, transmits the converted optical signal, and converts the transmitted optical signal into a second electrical signal. The optical transmission system includes an electrooptic conversion device, an optical transmission path, and a photoelectric conversion device. The first electrical signal includes a high-frequency communication signal of above 9 MHz and 10 GHz or less. The optical transmission system further includes an additional signal generating device for generating a low-frequency additional signal having a frequency of 1 Hz or more and 9 MHz or less. The electrooptic conversion device converts the first electrical signal including the additional signal generated in the additional signal generating device and the communication signal into the optical signal.

摘要： A ventilation assembly of the present disclosure includes: an internal member being a tubular body having an opening at a first end portion and an opening at a second end portion; an external member being a tubular body having a bottom; and a gas-permeable membrane covering the opening at the first end portion of the internal member, wherein the external member is joined to the internal member with the internal member inserted in the interior of the external member from the first end portion side, the ventilation assembly has a second space serving as a ventilation path connecting the gas-permeable membrane and the outside of the ventilation assembly in at least one selected from the inside of the internal member, the inside of the external member, and an interspace between the internal member and the external member joined together, and the internal member includes one first projecting portion or two or more first projecting portions projecting from the inner peripheral surface at a position on the second end portion side with respect to the gas-permeable membrane. The ventilation assembly of the present disclosure can prevent the gas-permeable membrane from being damaged at the time of fixation to the projection even when the ventilation assembly is reduced in height.

摘要： An electromagnetic shield is disposed in front of a radar. The radar has different angles of view in different directions. The radar has a first angle of view in a first direction and a second angle of view in a second direction. The second angle of view is smaller than the first angle of view. The second direction is orthogonal to the first direction. The electromagnetic shield has a pair of first sides and a pair of second sides. The pair of first sides face each other in the first direction. The pair of second sides face each other in the second direction. The electromagnetic shield includes a dielectric. At least one of the pair of first sides includes a structure having at least one selected from the group consisting of a projecting portion and a recessed portion.
