A new and distinct Miniature rose plant is provided which abundantly forms on a substantially continuous basis attractive bronze colored blossoms. The inner layer includes a first set of openings covered by an air permeable material. This apparatus can avoid mistaken activation or inactivation of a protection function at the time of re-lighting of the light source due to the influence of the residual heat after the light source is turned off. In one embodiment, the weighting would be used in conjunction with a Pin Yin translation program so that a user could set some terms, and allocate a search weight to the remaining terms. The piezoelectric actuator includes: a moving member having a predetermined length and moving in a forward or a backward direction; and a piezoelectric portion contacting the moving member and moving the moving member linearly using a vibration generated when a piezoelectric element contracts or expands in response to an electrical signal.
