  • Publication number: 20230021363
    Abstract: One of problems is to provide a feed composition having both immunostimulatory action and mold toxin adsorbing action. Another one of the problems is to provide a technique for minimizing decomposition of a feed composition made using yeast. Yet another one of the problems is to provide a method of inexpensively manufacturing the above-mentioned feed composition. The feed composition is obtained by inclusion of nucleic acid having molecular weights ranging from 5,000 to 100,000, a yeast cell wall component/yeast cell wall components, and ligno sulfonic acid. A feed composition may be manufactured by supplying nucleic acid and a yeast cell wall component that are both derived from a raw material, yeast. To supply the nucleic acid and a yeast cell wall component/yeast cell wall components from the yeast, the yeast may be subjected to alkaline treatment to prepare the nucleic acid and enucleated yeast.

  • Patent number: 9590543
    Abstract: The purpose of the present invention is to reduce noise by controlling vibration due to rotation fluctuation, and to consume only current required for maintaining the rotation by bringing the current for driving a motor closer to a state of synchronization. A drive means drives a sensorless brushless DC motor by switching an energization pattern at a constant frequency to determine the rotation position of the rotor of the sensorless brushless DC motor. A detection means detects a zero-cross signal representing the switching of the phase of the rotor. A calculation means calculates a synchronization determination rate representing a percentage of the number of detected zero-cross signals. A pulse width control means controls the pulse width of a PWM drive duty in the drive means so that the calculated synchronization determination rate falls within a target range.
