  • Method for producing cyclic enol ether compound
    Patent number: 11840542
    Abstract: Provided is a one-step method for producing an enol ether using a diketone of a macrocyclic compound as a starting material. A method for producing a compound represented by general formula (I) includes reacting a compound represented by general formula (II) in the presence of a metal catalyst containing at least one metal element selected from the group consisting of magnesium, aluminum, zirconium, titanium, and samarium, and an alcohol containing at least one selected from the group consisting of a primary alcohol and a secondary alcohol to obtain the compound represented by general formula (I).
    Type: Grant

  • Electric power receiving device and method of receiving electric power
    Patent number: 9590428
    Abstract: An electric power receiving device in one aspect of embodiments of the present disclosure comprises an electric power receiving section and a converting section. The converting section comprises a compensation voltage generating section. The compensation voltage generating section generates a compensation voltage capable of canceling out a reactance component in the electric power receiving section, and applies the compensation voltage to the electric power receiving section. The compensation voltage generating section comprises a phase changing section, a physical quantity detecting section, and a searching section. The searching section searches a target phase of the compensation voltage that brings the electric power receiving device into a substantially resonant state, based on a physical quantity detected by the physical quantity detecting section.
