    摘要: It is an object to provide a blade member for an airplane which is simple in structure, and moreover is excellent with respects to weight, aerodynamic performance, cost, strength and durability. A vane of a double-slotted flap includes: an outer skin area surrounded by a first outer skin, a second outer skin, a leading edge and a trailing edge each having a predetermined wall thickness. Front and rear reinforcing areas are provided that extend in a span direction within the outer skin area and are connected to the first outer skin and the second outer skin. The outer skin area and the reinforcing areas are integrally formed by wire electrical discharge-machining. The first outer skin and the second outer skin respectively have thickened portions thicker than the other portions, and the trailing edge is formed to have a thickness which is approximately zero. This blade member can be simplified in structure, leading to reductions in the number of parts, number of assembling steps and weight. Moreover, no step nor seam is generated on a surface of the blade member, and hence it is possible to prevent an increase in drag and the generation of corrosion.

    摘要: A surface acoustic wave device (e.g., filter or convolver) is designed to increase an electromechanical coupling factor K2 and is basically configured by a substrate, a buffer layer, a piezoelectric layer and an electrode layer. Herein, the substrate is made of a bulk material (e.g., SrTiO3), which allows growth of a perovskite compound crystal being expressed by a general chemical formula of SrZO3 (where Z denotes an element such as Zr and Sn whose valence is 4). The buffer layer is formed on the substrate and is made of the perovskite compound crystal (e.g., SrZrO3, SrSnO3), which has good lattice matching with KNbO3. The piezoelectric layer is made of a KNbO3 single crystal and is formed on the buffer layer with a thickness of 500 nm or so. The electrode layer is formed on or below the piezoelectric layer. An interdigital transducer consisting of input and output electrodes is formed by patterning using photolithography technique being effected on the electrode layer, which is made of a metal material (e.g., Al). In addition, it is possible to form a temperature stabilization layer between the piezoelectric layer and electrode layer. The temperature stabilization layer is made of a material (SiO2) having a temperature coefficient reverse to a temperature coefficient of the piezoelectric layer so as to ease distortion being caused to occur due to differences in thermal expansion between the piezoelectric layer and electrode layer. Incidentally, the temperature stabilization layer has a prescribed thickness, which is approximately 1000 nm.

    摘要: An air gun apparatus which permits stable, fine spinning and is capable of discharging fine filaments at a certain degree of dispersion and affording a non-woven fabric of uniform shape is provided. The air gun includes an air nozzle and an accelerator tube. The air nozzle has a filament inlet and outlet. The filaments are discharged from the filament outlet while being pulled by compressed air. The accelerator tube is formed at a specific diameter to length ratio and is connected to the air nozzle in the filament discharging direction. The non-woven fabric producing apparatus is provided with a guide tube and a separator nozzle, with an air flow rate regulator being disposed between the guide tube and the separator nozzle. The air flow rate regulator has an exhaust port for exhausting to the exterior a portion of the compressed air which is used for carrying the filaments.

    摘要: An MIM type of electron emission element having a thin insulating film formed below an electron emission region of a metal layer, with that electron emission region of the metal layer consisting of an array of thick and thin portions, distributed throughout the electron emission region. Improved efficiency and uniformity of of emission are obtained, due to the low resistance of the thick portions, which apply a supply voltage to the thin portions of the metal layer, while the thin portions can be made sufficiently thin to maximize the electron emission.
