  • Publication number: 20200177036
    Abstract: A method for manufacturing a rotor magnet of a rotor of a permanent magnet motor, the rotor magnet including plural main magnets and plural auxiliary magnets, the main magnets being magnetically oriented in a first direction, the auxiliary magnets being magnetically oriented in a second direction, the auxiliary magnets being disposed respectively between the main magnets. The method includes: in the rotor, forming a divided resin molded part by resin-molding the main magnets and the auxiliary magnets, the main magnets and the auxiliary magnets being arrayed in an arc-like shape whose circumference is divided into plural parts, the main magnets being not yet magnetized, the auxiliary magnets being magnetized in the second direction; magnetizing the main magnets of the divided resin molded part in the first direction; and connecting a plurality of divided resin molded parts in a circular shape.

  • Publication number: 20170347688
    Abstract: A liquid composition obtained by subjecting a fruit peel part of a citrus fruit with a cut space of from 0.5 to 5.0 mm on a surface to extraction in a solvent, the liquid composition containing an aroma component and a bitterness component; a container-packed beverage obtainable by mixing a liquid composition as defined above and a raw material for a beverage; and a method for producing a liquid composition, including subjecting a fruit peel part of a citrus fruit with a cut space of from 0.5 to 5.0 mm on a surface to extraction in a solvent, thereby preparing a liquid composition, the liquid composition containing an aroma component and a bitterness component of the citrus fruit. The foodstuff using the liquid composition of the present invention have “crispness” and “freshness” of the citrus fruit, so that the foodstuff can provide new tastes as luxurious products.

  • Publication number: 20170107466
    Abstract: An object of the present invention is to provide a technique for masking the bitterness and astringency of an unrefined distilled plum liquor. By incorporating a specified amount of at least one selected from isobutyric acid, acetic acid, and benzaldehyde in an unrefined distilled plum liquor, there can be provided a distilled plum liquor in which the bitterness and astringency derived from the unrefined distilled plum liquor is masked.

  • Publication number: 20160316802
    Abstract: Provided are a method that makes it possible to recover a fresh and favorable aroma component from a biological ingredient while reducing the yield of recovering an unfavorable aroma component, as well as an apparatus that can be used in said method. A favorable aroma component is easily, selectively and efficiently recovered from a biological ingredient, not only by recovering a distillate by a conventional steam distillation method, but also by causing that part of aroma component, which passes through as a gas without being condensed at a cooling step, to be recovered in a liquid by gas-liquid contact.

  • Patent number: 8943860
    Abstract: A vibration control device for a washing machine is composed of a drum to house laundry, a washing tank to house the drum which is suspended by a chassis of the washing machine, a drum driving motor, an acceleration detecting unit to detect an acceleration in the horizontal direction of the washing tank, a linear actuator fixed to the chassis of the washing machine to generate a driving force in the horizontal direction to the chassis of the washing machine, a force transmitting unit to connect a movable axis of the linear actuator with the washing tank, and a control unit to control the driving force of the linear actuator based on the acceleration detected by the acceleration detecting unit. The force transmitting unit transmits the driving force and absorbs mechanistically relative displacement in the back and forth direction and in the up and down direction.
