Abstract: Pluripotent stem cells are suspension-cultured with the undifferentiated state thereof maintained. In suspension culture of pluripotent stem cells, the undifferentiated state is maintained by the presence of a PKC inhibitor, especially, a PKC? inhibitor, and a tankyrase inhibitor (TNKS inhibitor).

Abstract: A coating is formed on a surface of a base material of a furnace, and includes a base layer and a sliding material layer that is formed on a surface of the base layer and contains an oxide ceramic and a compound having a layered crystal structure. The sliding material layer causes the collided ashes to be slipped and facilitates the drop off of the adhered ashes. The base material forms a heat transfer tube or a wall surface of the furnace.

Abstract: Message display control means updates and displays messages sequentially on a message list screen each time message receiving means receives a message. When input detection means detects a response message, identification means identifies the latest message at the time of detection and the response message. Response message sending means sends the response message as a response to the identified message to other participants upon completion of input of the response message. Therefore, even in the case where the message list screen is updated due to receiving the subsequent message during the input of the response message, the completed response message is able to be sent back to the response object message.

Abstract: A heat exchange module has a restriction protrusion that is provided to protrude between a blade of a cooling fan and a core portion of a heat exchanger and that restricts the blade from approaching the core portion more than a predetermined position. In a state where one side of an outline of a rectangular shaped fan shroud is disposed so as to face an installation surface, the restriction protrusion is provided in a position where the amount of water reaching the cooling fan through the heat exchanger becomes greater than the amount of water at position just below a rotation axis of the cooling fan in a case where at least a portion of the fan shroud is submerged in water.

Abstract: An air-blowing device has a blower fan that is an axial fan located on a downstream side of a heat exchanger in an airflow direction and supplies air to the heat exchanger and a shroud that supports the blower fan and forms an air passage extending from the heat exchanger to the blower fan. At least one side of a periphery of the heat exchanger is arranged to overlap with an outermost peripheral portion of the blower fan that is outermost in a radial direction of the blower fan when viewed in the airflow direction. The shroud has an air-introduction part that is (i) disposed, in a portion in which the ring part and the connection part connect to each other, on a surface of the connection part facing the heat exchanger and (ii) formed concentrically to be centered at a rotational axis of the blower fan. A part of the air-introduction part protrudes outwardly from a periphery of the connection part in the radial direction of the blower fan when viewed in the airflow direction.

Abstract: A blower fan includes a plurality of blades radially extending from a boss provided at a rotary center and spaced apart from each other in the rotational direction, and a ring portion connecting outer peripheral ends of the blades in a ring shape. A radially outer end part at an end on an air-flow upstream side of the ring portion is positioned outward in a radial direction of a rotary shaft in the blower fan, as toward the air-flow upstream side. Thus, the blower can prevent the backflow air from being swirled, thereby reducing noise.
