Abstract: Provided are a two-component curable coating agent capable of forming a surface protective layer having excellent weather resistance, acid resistance, fouling resistance, and elongation properties, and a multilayer film including a surface protective layer that is a cured film of the two-component curable coating agent. The two-component curable coating agent of the present invention includes: a main agent that contains a polyol containing an acrylic polyol having an alicyclic structure and a hydroxyl value of 36 mgKOH/g or more and 125 mgKOH/g or less, and an alkyl polyol; and a curing agent that contains a polyisocyanate. The multilayer film of the present invention includes: a substrate layer; and a surface protective layer that is integrally layered on a first surface of the substrate layer and is a cured film of the two-component curable coating agent.

Abstract: An exhaust catalyst management apparatus to be applied to a vehicle includes a differential pressure sensor and one or more processors. The differential pressure sensor detects an accumulation state of an exhaust-containing substance in a catalyst device. The one or more processors are coupled to the differential pressure sensor and a vehicle outside sensor. The one or more processors determine whether or not travel environment is suited to carrying out an output control for removal, based on a result of the detection of surroundings of the vehicle by a vehicle outside sensor. Upon determining that the travel environment is suited to carrying out the output control for removal, the one or more processors carry out the output control for removal, while the vehicle is traveling, in accordance with a result of the determination of the accumulation state of the exhaust-containing substance in the catalyst device.

Abstract: A gas filtering device includes an element and a case. The element includes a filter that filters a gas and a frame that holds a periphery of the filter. The case accommodates the element. The case includes a first member and a second member that are coupled to each other with the element interposed therebetween. The first member includes a frame holder that holds a periphery of the frame when the first member is coupled to the second member, and a temporary holder that performs temporary holding of the frame so that a part of the frame is separated from the frame holder and the frame is curved when the first member is not coupled to the second member. The second member includes a temporary-holding canceller that cancels the temporary holding of the frame by the temporary holder when the second member is being coupled to the first member.

Abstract: Provided are a method of maintaining the ovaries of marine fish, and a method of obtaining fertilized egg. Provided is a method of maintaining ovaries in which the ovaries are removed from marine fish and the ovaries or fragmented ovaries are cultured in a culture solution. Also, provided is a method of obtaining fertilized eggs of marine fish, the method including allowing ovaries, which have been maintained after removal to ovulate and performing artificial insemination. Further, the present invention relates to a method of maintaining the fertilization capability of ovulated eggs of marine fish by using the culture solution. According to the present invention, fertilized eggs of marine fish can be easily obtained and seed can be efficiently produced.

Abstract: A travel assistance device includes a first rail inclined downward from a first end portion side to a second end portion side in longitudinal direction, a second rail provided parallel to the first rail and inclined, in opposite direction to the first rail, downward from the second end portion to the first end portion in the longitudinal direction, a holding member having a runner portion slidably guided by the rails and holding a travelling body, and a switch mechanism configured to be switched between a state in which the runner portion is guided by the first rail and is assisted to travel downward on the first rail by a load applied to the runner portion and a state in which the runner portion is guided by the second rail and is assisted to travel downward on the second rail by the load applied to the runner portion.
