  • Publication number: 20240116075
    Abstract: A selective film deposition method includes exposing a substrate having a structure on which a first surface region containing a metal element and a second surface region containing a nonmetal inorganic material are both exposed, to a solution containing an organic substance represented by formula (1) shown below and a solvent to deposit a film of the organic substance on the first surface region selectively over the second surface region: R1(X)m (1) wherein R1 is a C4-C100 hydrocarbon group optionally containing a heteroatom or a halogen atom, and m hydrogen atoms of the hydrocarbon group are replaced with X; X is —PO3(R2)2, —O—PO3(R2)2, —CO2R2, —SR2, or —SSR1; each R2 is a hydrogen atom or a C1-C6 alkyl group; and m is a positive integer, and m/r is 0.01 to 0.25 where r is the number of carbons of the hydrocarbon group.

  • Publication number: 20060013593
    Abstract: Disclosed is a light-intensity modulation element, which comprises a substrate made of a nonlinear optical crystal, and a light waveguide formed in a principal surface of the substrate to extend in one direction. The light waveguide includes first and second wavelength conversion portions for converting a part of infrared light introduced into the light waveguide to a second harmonic. Each of the first and second wavelength conversion portions has a plurality of polarization structures serially disposed in the longitudinal direction of the light waveguide in such a manner that their polarities in the thickness direction of the substrate are inverted periodically and alternately in the longitudinal direction of the light waveguide. The light waveguide further includes a phase adjustment portion located between the first and second wavelength conversion portions, and associated with a pair of electrodes disposed in opposed relation to one another on opposite sides thereof.

  • Patent number: 4840059
    Abstract: A method for adjusting the fuel injection quantity of an electromagnetic fuel injector having a needle valve, an electromagnetic actuator composed of a movable core which moves with the needle valve and a fixed iron core for attracting the movable core to move the needle valve to its open position, an adjust pipe inserted within a through hole of the fixed iron core, and a spring interposed between the adjust pipe and the movable core for continuously biasing the needle valve to its closed position, has the steps of inserting the adjust pipe into the through hole of the fixed iron core by a predetermined length and temporarily fixing the adjust pipe to the fixed iron core so as not to be moved by a force received from the spring when the needle valve is operated and so as to start moving when a force larger than the above described force of the spring is applied, running in the injector for a predetermined period of time, finely adjusting the position of the adjust pipe while checking the actual fuel injectio
