Abstract: A windmill, characterized by connecting blade root parts to a hub in the radial direction of a windmill shaft by an undercut, fitting structure which is suitable particularly for a small-sized windmill having FRP blades. By this structure, the blades can be connected to the hub at the blade root parts without basically requiring a bolt fastening structure, a reduction in the weight of the blades can be achieved, and the strength, rigidity and installation accuracy of connection parts between the blades and the hub can be satisfactorily maintained.

Abstract: The present invention provides an indoor unit of an air conditioner, which is capable of improving the safety regarding the opening and closing movements of a movable panel. An indoor unit of an air conditioner includes a front grill, a second panel, a driving machine, and a second panel supporting member. The front grill is provided with a first intake port at a front thereof. The second panel is provided such that it covers the first intake port, opens the first intake port by moving away from the first intake port and closes the first intake port by moving close to the first intake port. The driving machine generates a driving force to move the second panel. The second panel supporting member has a gear portion and a plate member. The gear portion transmits the driving force of the driving machine to the second panel. The plate member is provided outside the gear portion, and covers a gap between the second panel and the front grill in a state in which the second panel is open.
Abstract: The present invention provides an indoor unit of an air conditioner, which is capable of improving the mounting accuracy between a front grill and a movable panel. An indoor unit of the air conditioner includes a main body casing, a front grill, a second panel, a driving machine, and an opening and closing mechanism. The front grill is provided forward of the main body casing and includes a first intake port. The second panel is capable of moving so as to open and close the first intake port. The driving machine is provided in the main body casing, and generates a driving force to move the second panel. The opening and closing mechanism is provided at the front grill, and moves the second panel by the driving force of the driving machine to open and close the first intake port.
Abstract: A pressing diaphragm and a pressing filter plate of a compression type filter press in which a surface of a main body of a pressing filter plate is covered with the pressing diaphragm, include: a projection member provided on the surface; and a projection member mounting member capable of contacting the main body, provided in a rear surface at a position corresponding to the projection member, and for mounting the projection member thereon with a fixture. The projection member has a plurality of pillar portions mounted on the projection member mounting member and fitted in a through-hole of the pressing diaphragm, a mounting hole penetrating through each of the pillar portions, and a long connecting plate portion for connecting the pillar portions with each other and regulating expansion of the pressing diaphragm fitted into a periphery of the pillar portions.
Abstract: An expressing filter plate comprising a base plate and a diaphragm sheet covering the base plate and having a filter surface, with a pressure fluid chamber formed between the base plate and the diaphragm sheet. The diaphragm sheet is formed, in its peripheral portion to be clamped between pressed filter plates, with a fluid passing opening in communication with a fluid passage in the base plate. A covering member having a tubular portion fitting in the opening is made of a material having higher hardness than the diaphragm sheet. The covering member has a flange portion formed with fluid grooves for maintaining the tubular portion in communication with filtrate grooves in the filter surface of the diaphragm sheet.
