Abstract: PROBLEM TO BE SOLVED: To easily control the preferential orientation of crystals of films and to control the intensity of the orientation thereof without heating a substrate by property selecting the ions at the time of irradiation with ions and adjusting the energy of the irradiation with the ions. SOLUTION: This film forming method comprises executing vapor deposition of a material and the irradiation with the ions in combination on the film to be formed with (IVD method). While the crystallinity of the films may be controlled by changing film forming factors, the ion irradiation energy and ion spiced in patricularly among the various factors strongly affect the preferential orientation of the crystals and the orientation intensity thereof in this IVD method. Then, the preferential orientation of the crystals and the orientation intensity thereof may be controlled by properly changing the ion species and irradiation energy in the irradiation with the ions, and the plural processes for the control are not needed.  There is no need for controlling the film characteristics by heating the substrate and the film formation by a low-temp. process by cooling the substrate is made possible. As a result, the width of the selection of the substrate is expanded and the formation of an oriented film on, for example, the high-polymer substrate is made possible as well.

Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To improve the uniformity of spray of a fuel injection valve by providing a means to suppress a deviation of the flow velocity distribution in an axial direction of an injection nozzle for fuel flowing into the injection nozzle. SOLUTION: The inner bottom of a fuel injection chamber 16 opened and closed by a needle valve 12 is formed in a semispherical shape and an injection nozzle 17 is obliquely formed in the bottom thereof. To suppress the occurrence of a deviation of the flow velocity distribution in an axial direction of the injection nozzle 17 for fuel flowing in the injection nozzle 17, the position of the injection nozzle 17 is deviated in a direction in which it is rotated by 90 deg.C in a revolution direction of fuel from the inclination direction of the injection nozzle 17 based on the central part of the bottom of the fuel injection chamber 16. This is because when the injection nozzle 17 is formed in the central part of the bottom of the fuel injection chamber 16, a flow velocity in an axial direction is reduced to a minimum at 90 deg. and increased to a maximum at 270 deg..  The rotation amount of the injection nozzle 17 is set to a value within a range in which a connection part between the inner peripheral surface of the fuel injection chamber 16 and the inlet part of the injection nozzle 17 is not formed in a stepped state. Further, the whole periphery of the inlet part of the injection nozzle 17 is formed in a circular arc shape and the inner peripheral surface of a fuel injection chamber 16 and the inlet part of the injection nozzle 17 are interconnected through a continuous gentle curve.
