  • Patent number: 10327580
    Abstract: Provided is a coffee maker where a heated state coffee liquid can be obtained by performing an extraction operation in an extraction unit, and can be sufficiently cooled down to a temperature, to provide tasty iced coffee, and in which a cooled state of the coffee liquid can be maintained. An ice basket is arranged inside a server, and is disposed to receive and disperse the coffee liquid that is dripping from an extraction unit. The ice basket is formed in a vertically elongated shape, and internally includes an ice storage. A liquid feeding hole, which feeds the coffee liquid inside the ice storage to the server, is formed in a peripheral edge portion of a bottom portion. The bottom portion is arranged at a position close to a bottom surface of the server while being separated from the bottom surface.

  • Patent number: 9854944
    Abstract: A coffee beans grinder includes a main body, a dispensing component, a blade unit for grinding coffee beans having a first blade element and a second blade element facing the first blade element, and a dispensing element provided in the dispensing component for feeding coffee beans to a grinding space defined between the first blade element and the second blade element. The first blade element is provided in the main body, and the second blade element is provided in the dispensing component. The dispensing component is removably attached to the main body with a manually-operable engagement element. The second blade element faces the first blade element to define the grinding space therebetween with the dispensing component being attached to the main body with the manually-operable engagement element.

  • Patent number: 5634530
    Abstract: A lubricating device lubricates various parts of a power transfer system for a vehicle. The lubricating device comprises a gear interconnected with an output shaft and splashes lubricating oil in an oil chamber. The splashed oil is received by a cover member and supplied to a passage for supplying the lubricating oil to a bushing for rotatably supporting an output shaft of the power transfer system. Therefore, even if the direction to which lubricating oil is splashed by the gear is changed according to an operating condition of the vehicle, the cover member securely receives the splashed oil and supplies it to the passage for the bushing.

  • Patent number: 5167164
    Abstract: The rotational speed of a motor is reduced by a worm gear and a worm wheel and the reduced rotation is transferred to a first pinion gear. A first moving plate is moved along a pair of shafts. A second moving plate is provided for the first moving plate by inserting to the same pair of shafts. A first coil spring is interposed between a retaining portion of a shaft inserting hole of the first moving plate of one of the shafts and a retaining portion of a shaft inserting hole of the second moving plate. The first coil spring is compressed by the movement of the first moving plate upon switching to the 4-wheel drive, thereby accumulating the force. A second coil spring is interposed between a retaining portion of the shaft inserting hole of the first moving plate of the other shaft and a retaining portion of the shaft inserting hole of the second moving plate. The second coil spring is compressed by the movement of the first moving plate upon switching to the 2-wheel drive, thereby accumulating the force.
