摘要:
In the production of a decorative sheet, a synthetic resin paste is first applied onto the upper surface of a substrate sheet to form an undercoat layer. Then, one or more pastes, each being of the same material and having approximately the same viscosity as the paste of the undercoat layer, are laterally sprayed so as to drop onto the undercoat layer. The result is a smoothing phenomenon, with the pattern layer cooperating with the undercoat layer to form a smooth patterned surface. Finally, the pattern layer is heated and jelled.

A metal laminated substrate for an oxide superconducting wire is produced by removing, in a state where a copper foil to which rolling is applied at a draft of 90% or more is held at a temperature below a recrystallization temperature, an absorbed material on a surface of the copper foil by applying sputter etching to the surface of the copper foil; removing an absorbed material on a surface of a nonmagnetic metal sheet by applying sputter etching to the surface of the nonmagnetic metal sheet; bonding the copper foil and the metal sheet to each other by reduction rolls at an applied pressure of 300 MPa to 1500 MPa; orienting crystals of the copper by heating a laminated body obtained by bonding at a crystal orientation temperature of copper or above; and forming a protective layer on a copper-side surface of the laminated body by coating.

Disclosed are a polymer laminated substrate for forming an epitaxial growth film having a highly-crystal-oriented surface and a method of manufacturing the polymer laminated substrate. The method of manufacturing a polymer laminated substrate for forming an epitaxial growth film includes the steps of: activating at least one surface of a polymer sheet T1; activating at least one surface of a metal foil T2 which is made of Cu or a Cu alloy and is formed by cold rolling at a draft of 90% or more; laminating the polymer sheet and the metal foil such that an activated surface of the polymer sheet and an activated surface of the metal foil face each other in an opposed manner and applying cold rolling to the polymer sheet and the metal foil which are laminated to each other; and biaxially orienting crystals of the metal foil by heat treatment.

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.

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.

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.

摘要:
A program analysis support device that can freely combine program analysis conditions and can realize desired program analysis. An analysis condition setting part inputs a program analysis condition in a form of a conditional equation (analysis command, an analysis subject, and analysis condition) having an inherent equation number. A POU list extraction processing executing part executes an analysis command that reads a program to generate a collection of POUs serving as analysis subjects constituting the program, and a variable use list extraction processing executing part executes an analysis command that extracts a cross-reference of a variable to extract a cross-reference of a variable to the POU collection serving as the analysis subject. Both the parts further extract a cross-reference of a variable to another POU collection. An AND processing part further performs processing of a logical product of the cross-references of both the variables and outputs a result thereof to an analysis result display part.
