摘要： PURPOSE: To reduce a quantity of heat and power consumption required for the title device by a method wherein a magnetic field having a component perpendicular to an electric current applied to a heater layer which is provided to a buckling body is applied to the electric current by means of a magnet so that the buckling body is deformed by the heat expansion and a Lorentz force due to the electric current. CONSTITUTION: In a head section of an ink jet recorder, a heater layer 2 is provided beneath a buckling body 1 by being nipped with a plurality of insulation layers 3, 4. A permanent magnet or an electric magnet is provided to the head section or a printer body. When the heater layer 2 is energized, the heater is heated to heat the buckling body 1 and it receives a Lorentz force toward an orifice side because the heater layer 2 is in a magnetic field. The heater layer 2 and buckling body 1 are bonded to each other so that the buckling body is deformed toward the orifice side by virtue of the increasing of the internal stress due to the thermal expansion and by receiving a force from the heater layer 2, thereby increasing a pressure in a pressure chamber to eject an ink.

摘要： PURPOSE:To reduce the occupying area of interconnection on the surface of a substrate and reduce interconnection resistance by forming a recessed groove on the surface of the substrate, forming a first interconnection layer in the groove and providing a second interconnection layer along the surface of the substrate so as to connect the first interconnection layer with an electronic component element. CONSTITUTION:Insulating SiO2 films are formed on both front and rear planes of a substrate 1, and a base layer 3 for plating films are provided on the SiO2 film. On the base layer 3, a buckling body 4, an interconnection layer 5 and a flattening layer 6 are formed by aligning them almost on the same flat plane. The interconnection layer 5 is formed of a first interconnection layer 5a in a recessed groove 9 formed on the surface of the substrate 1 and a second interconnection layer 5b formed along the surface of the substrate 1, and a spacer layer 7 and a nozzle plate 8 are successively formed on the top plane of the flattening layer 6. Thus, the occupying area of the interconnection on the surface of the substrate 1 is reduced, and the interconnection resistance is reduced.

摘要： PURPOSE:To enhance the pressure of ink by buckling deformation by constituting a pressure generator of a buckling structure driven by a temp. change and the substrate supporting the buckling structure through a spacer and having ink passages. CONSTITUTION:When a current is applied through electrodes 9a, 9b, a buckling structure 3 is heated by resistance heat tending to thermally expand. However, since the buckling structure 3 is fixed at both ends thereof in this case, it can not generate expansive deformation and compression force is generated in a predetermined direction. When this compression force exceeds buckling load, buckling deformation is generated and an unfixed buckling part is deformed toward a nozzle plate 1 and the pressure is transmitted to the ink in the space between the buckling structure 3 and the nozzle plate 1 and an ink droplet 6 is formed from a nozzle orifice 2 to be jetted to the outside. Since the buckling structure is extremely simple in its structure and can obtain large displacement quantity even if the shape thereof is small, a head can be miniaturized.

摘要： PROBLEM TO BE SOLVED: To obtain an image sensor capable of being made high in performance, low in cost and improved in reliability by maintaining the linearity of the array of a waveguide outgoing end in the thickness direction of a light transmission substrate. SOLUTION: In this image sensor 21 of an optical waveguide contracting optical type, a first thermal expansion suppressing member 26 is stuck to one side surface of the thickness direction D2 of the rear end part 32 of a light transmission member 24 having plural waveguide 23. The linear expansion coefficient of the member 26 in an array direction D1 is smaller than that of the member 24 in the direction D1. The bending rigidity of the member 26 in the direction D2 is in such a degree than can maintain linearity with respect to the thickness direction D2 of the array of a waveguide outgoing end 28. The plane degree of an adhering surface 35 with the member 24 of the member 26 is >=0 μ and >=5 μ. Thus, the thermal extension of the part 32 of the member 24 is suppressed and the linearity of the array of the end 28 in the direction D2 is sufficiently maintained.

摘要： PROBLEM TO BE SOLVED: To obtain a simple device capable of uniformly spraying spacer particles at a low cost by providing the device with a passage for passing the spacer particles and a shielding member for shielding the passage of the spacer particles by a curvilinear action. SOLUTION: A carrier gas 9 presses the spacer particles 10 downward from between a gap adjusting part 2 and a counter member 5. The spacer particles 10 are sprayed from a nozzle 8 past the passage 11 when the spacers 10 are inserted into the space enclosed by a buckling structure body 1, a spacer 3 for forming the gap and a counter member 5. On the other hand, the buckling structure body 1 is superheated and tends to extend longitudinally when a current is passed to the buckling structural body 1 by impressing voltage on an electrode 6a. A gap adjusting part 2 is, however, fixed and cannot, therefore, extend. When, thereupon, compressing power P0 exceeds the buckling load, the buckling structural body 1 induces buckling deformation and the central part thereof is deformed to a counter member 5 side, by which the passage 11 is closed and the spraying of the spacer particles 10 from the nozzle 8 is shut off.

摘要： PROBLEM TO BE SOLVED: To provide an Al etching soln. having a selectivity to Ni. SOLUTION: An Ni layer 5 is formed on a glass substrate 1, and an Al layer 2 is formed on the Ni layer 5, and a resist coating film 3a having a desired shape is formed on the Al layer 2. By etching this layered body by using a boric acid aq. soln. of 5-25.4wt.% concn. or a strongly alkaline developer for positive photoresist, the Ni layer 5 is not etched but the Al is etched. As the result, a patterning of the Al on the substrate laminating the Al layer on the Ni layer which is conventionally difficult is executed easily.
