Abstract: A tabular structure having flexibility extends from a root end portion to a distal end portion along a reference axis. The root end portion is fixed to a pedestal. Three sectioned parts are provided in the tabular structure. Weights are joined to the lower surfaces of the respective three sectioned parts. The three sectioned parts respectively have different thicknesses. As a result, spring constants are different. When vibration energy from the outside is applied to the pedestal, the weights vibrate and a bend occurs in the tabular structure. If a charge generating element such as a piezoelectric element is stuck to the tabular structure, an electric charge is generated by bending stress. A frequency band capable of generating electric power is expanded by providing a plurality of weights in the tabular structure in which the spring constants are different in each of the sectioned parts.

Abstract: The present invention is a method for hair dyeing or bleaching by discharging in a foam from a squeeze container 6 a mixed solution of a first agent A1 and a second agent A2 of a two-part hair dye or bleach composition to apply on the hair. In the present invention, the squeeze container which includes a container body 4 and a squeeze foamer 5 is used as the squeeze container 6. At least one of the first agent A1 or the second agent A2 contains a foaming agent. The mixed solution of the first and second agents has a viscosity (25° C.) of from 1 mPa·s to 100 mPa·s. The first agent A1 and the second agent A2 are mixed in the container body 4 so as not to produce a foam. Squeezing is carried out with the squeeze container 6 stood upright so that the mixed solution A3 does not reach an air induct path 12 of the squeeze foamer 5. As a result, the mixed solution of the first and second agents of the two-part hair dye or bleach composition can be stably discharged in a fine foam using a squeeze container.
