  • Patent number: 10221917
    Abstract: A method for storage of excess energy which would otherwise be lost, the regulation of angular velocity, and prevention of excessive velocities is disclosed. The device consists of a bowl shaped container, divided into sections by radially oriented vertical walls, which holds a fluid (any appropriate liquid or set of small solid particles), and spins on its vertically oriented axis at various angular velocities. The floor of the device is formed in successive shapes of bowls and shelves, which allows for a kind of “gearing”. The invention allows more and more energy to be input into the device while the angular velocity is regulated within a particular range. A typical embodiment of the invention would include its attachment by a shaft at the axis to a vertical axis wind turbine.

  • Patent number: 10072728
    Abstract: A cushioning member between plate bodies of a mass body and at end portions, in the circumferential direction, so as not to rotate relative to the plate bodies. The peripheral edges, on both sides in the width direction, of the outer peripheral surfaces of the cushioning member's first and second side portions abutting against a support member, along with swing of the mass body, are chamfered, reducing the possibility that the cushioning member enters in a clearance between the side surfaces of the support member and the plate bodies when the cushioning members' first side portion and the support member abut, or when the cushioning member's second side portion and the support member abut, along with swing of the mass body, suppressing damage to the cushioning member.

  • Patent number: 8297083
    Abstract: Disclosed is a washing machine having ball balancers, which adjust a relation between a gap, between the inner wall of a racer of each of the ball balancers and balls, and viscous oil, so as to reduce the vibration and noise of the washing machine. Each of the ball balancers of the washing machine includes balls and viscous oil accommodated in a racer, and the viscosity of the viscous oil is varied in proportion to a gap between the racer and the balls. When the viscosity of the viscous oil is 1˜100 cSt, the gap is set to 0.5˜1.0 mm, when the viscosity of the viscous oil is 100˜380 cSt, the gap is set to 1.0˜2.0 mm, and when the viscosity of the viscous oil is 380˜1,000 cSt, the gap is set to 2.0˜3.0 mm. Thereby, the relation between the gap and the viscous oil is optimized, and the ball balancers effectively exhibit a balancing function and thus minimize the vibration and noise of the washing machine.
