Abstract: Provided is a pressure-sensitive element having more sufficient expandability, a relatively wide measurement range of pressure force, and a relatively simple structure, and an electronic device using the pressure-sensitive element. The pressure-sensitive element includes a plurality of first electrodes being elongated in first direction, arranged in a first plane, and including a conductive elastic body, a plurality of second electrodes being elongated in second direction intersecting the first direction, arranged in a second plane facing the first plane, and including a conductor wire, and a plurality of dielectrics covering a surface of the plurality of second electrodes. The plurality of second electrodes have bent parts K arranged periodically, and capacitance at intersections of the plurality of first electrodes and the plurality of second electrodes changes in accordance with pressure force applied between the plurality of first electrodes and the plurality of second electrodes.

Abstract: The present technology provides a method for manufacturing an aircraft water tank provided with a hollow body and a fiber-reinforced resin layer covering the hollow body. A blow molding step is performed in which polyolefin resin, a thermoplastic resin exhibiting superior durability against disinfectants, is blow molded to obtain a hollow body. Next, a surface treatment step is performed in which a surface treatment is performed upon the entire surface of the hollow body, thereby improving the adhesiveness of the entire surface. Next, a filament winding step is performed in which reinforcing fibers impregnated with a thermosetting resin are wound around the surface of the hollow body and the outer surfaces of the flanges and heated in order to cure the thermosetting resin, thereby forming the fiber-reinforced resin layer on the surface of the hollow body and the outer surface of the flanges.

Abstract: An inspection device is provided in which X-rays are radiated in a fan-like shape with respect to an extension direction of steel cords, are transmitted through a conveyor belt, and reach an X-ray line sensor. A control device makes an X-ray generator and the X-ray line sensor move in a fixed relative position at a certain speed within a certain movement range in a direction parallel with a plane and orthogonal to an extension direction of the steel cords. The control device generates two-dimensional image information on the basis of an X-ray transmission signal obtained each time the X-ray generator and the X-ray line sensor move a unit amount equal to a pixel pitch of the X-ray line sensor. The control device detects measurement information relating to the conveyor belt and the steel cords on the basis of the obtained two-dimensional image information.

Abstract: A tank port includes a reinforcing sheet, an inner member, and an outer member. The reinforcing sheet is attached around a through-hole on the outer peripheral surface of a cylinder. The inner member includes an inner fitting plate portion attached to the inner peripheral surface of the cylinder and an inner cylindrical portion inserted into the through-hole. The outer member includes an outer cylindrical portion attached to the outer peripheral surface of the inner cylindrical portion protruding from an opening and an outer fitting plate portion attached around the opening of the reinforcing sheet. The entire periphery of the through-hole of the cylinder is reinforced by being disposed between the inner fitting plate portion and the reinforcing sheet.

Abstract: An aircraft water tank constituting an aircraft water tank is provided with a cylindrical section, dome sections, and mouthpieces. The mouthpieces are provided with mouthpiece bodies and annular wall sections that extend outward in the radial direction around the entire outer circumferences of the mouthpiece bodies between an inner liner and a fiber-reinforced resin layer, and are attached to the inner liner and the fiber-reinforced resin layer around the circumferences of openings. Outer surfaces of the annular wall sections contacting the fiber-reinforced resin layer are formed by uniform tension curved surfaces.

Abstract: An insert nut is provided in a panel member made from a core member with a honeycomb structure, and a first and second surface plate and made from fiber reinforced plastic. A reinforcing member is provided at the location where the insert nut is provided in the core member. The insert nut is housed in a hole in the first surface plate, a hole in the first metal plate, and a hole in the reinforcing member, and fixedly attached with an adhesive. An inner circumferential surface of the hole in the first metal plate and an outer circumferential surface of the insert nut are in contact.
