A bubble removal method removes a bubble from liquid whose viscosity is reduced when shear occurs. A vessel whose volumetric capacity is variable is used. The interior of the vessel is depressurized and pressurized by increasing and decreasing the volumetric capacity of the vessel from a plurality of locations. As a result, the volume of the bubble is increased and decreased and the bubble is caused to move and be removed.

Bubble removal method and bubble removal device

A bubble removal method is for removing a bubble from liquid whose viscosity is reduced when shear occurs. A vessel, including a liquid inlet and multiple liquid outlets, whose volumetric capacity is variable and a means for giving resistance to the passage of liquid between the inside and the outside of the vessel are used. The liquid is passed through the vessel against resistance and the volumetric capacity of the vessel is increased and reduced. The interior of the vessel is depressurized and pressurized by the means for giving resistance to the passage of liquid in conjunction with increase and reduction in the volumetric capacity of the vessel.

A power source unit for use in vehicle is disclosed that effectively transfers energy between two power sources. The power source unit includes a main power source connected to input terminals of a current control circuit, such as insulation type power transfer circuit. In addition, a terminal of the main power source is connected to an output terminal of the current control circuit. The other terminal of the main power source is connected to a terminal of a parallel connection of a secondary power source and an electric power unit. The other terminal of the parallel connection is connected with a second output terminal of the current control circuit. Hence, energy from the main power source is transferred to the parallel connection of the secondary power source and electric power unit under the control of the current control circuit.
