The present invention relates to an apparatus of the loop Venturi reactor type for the continuous reaction of liquids with gases, in particular for hydrogenations, oxidations or acetylations, e. A capacitor unit is formed in the capacitor main body by a respective pair of first and second internal electrodes disposed in the main body in a face-to-face relationship with a dielectric material layer interposed therebetween. The head fixing member has an opening at a frame section, and fixes a plurality of the liquid ejecting heads that are inserted into the opening in a state where at least one portion of each of the nozzle plates protrudes through the opening. The variants for each repository object are arranged in a first hierarchy, and the layers for each variant are arranged in a second hierarchy.
