  • Oil formulations with thickeners
    Patent number: 9012515
    Abstract: This invention is based on unexpected effect of at least one thickener to maintain suspension or dispersion of solid particles in an oil medium. Such effect of thickener enables significant higher weight ratio of solid particles in such suspension composition as compared to previously known compositions. As a consequence, the suspension compositions provided herein enable more active ingredient in the solid particle to be present in a fixed volume or weight of such composition as compared to previously known compositions. One advantage of the suspension composition provided herein can be for aerial spraying of active ingredient such as herbicides, insecticides, or other growth regulating compounds.

  • Angular velocity sensor and synchronous detection circuit used therein
    Patent number: 9003883
    Abstract: In an angular velocity sensor, an upper electrode of a first piezoelectric element and a lower electrode of a second piezoelectric element are connected to an input terminal of a first Q/V conversion circuit, and a lower electrode of the first piezoelectric element and an upper electrode of the second piezoelectric element are connected to an input terminal of a second Q/V conversion circuit. Thus, vibration noise components of the quantities of charge generated at the first and second piezoelectric elements are cancelled out, and Coriolis components of the quantities of charge generated at the first and second piezoelectric elements are added, whereby only the Coriolis components are extracted.
