    摘要: A PDP and a manufacturing method for the PDP are provided, the PDP being capable of suppressing discharge delay due to improved discharge properties of a protective layer, and exhibiting superior image display performance despite having a high-definition cell structure. A magnesium oxide powder layer (16) is formed by distributing magnesium oxide particles (16a) flatly on a surface layer (8). Each of the magnesium oxide particles (16a) includes halogen atoms at and in a vicinity of the surface thereof. The magnesium oxide particles (16a) are manufactured such that the halogen atoms exist particularly at the surface of each of magnesium oxide particles (16a) through to a depth of 4 nm or less toward the core of each of the magnesium oxide particles (16a).

    摘要: An ultrasonic motor includes a stator and a rotor. In the stator, an n number of piezoelectric elements (wherein n is a natural number) are affixed to one surface of a vibrating member, whose outer circumferential edge is circular or polygonal, along a direction in which the outer circumferential edge extends. Each of the piezoelectric elements has a size corresponding to λθ/2 in terms of center angle, and the piezoelectric elements that are adjacent to each other are disposed so as to be separated by an interval corresponding to λθ/4 in terms of the center angle along a circumferential direction of the vibrating member. The piezoelectric elements are polarized in opposite directions in a thickness direction. The rotor is disposed so as to contact the stator, and is rotated by receiving vibration resulting from a 3n-wave traveling wave generated by the stator.
