A drive device includes a stator; a rotatably provided drive member; a piezoelectric element, which is nipped between the stator and the drive member in a tangential line direction of a rotation locus circle of the drive member, and expands and contracts in the tangential line direction at an expansion speed at the time of the expansion and a contraction speed at the time of the contraction, respectively, the expansion speed and the contraction speed different from each other; and a rotor provided concentrically with the drive member to touch the drive member with a pressure.

A piezoelectric actuator comprising an elastic plate 2 with a projection 3 provided on one of both surfaces of the plate. A first pair of strip-like piezoelectric elements 120a, 120b are fixed to the other of both the surfaces of the plate such that each of the first pair of piezoelectric elements is disposed along a first straight line passing through the position of the projection on a respective one of its opposite sides. A second pair of strip-like piezoelectric elements 122a, 122b are fixed to the same surface of the plate as the first pair of piezoelectric elements 120a, 120b such that each of the second pair of piezoelectric elements is disposed along a second straight line passing through the position of the projection perpendicular to the first straight line on a respective one of opposite sides of the position of the projection. Voltages are arranged to be applied to the respective piezoelectric elements of the first and second pairs as required so as to deform the plate, thereby causing the projection to deviate.

A performance apparatus 11 extends in a longitudinal direction to be held by a player, and is provided with an acceleration sensor 23. CPU 21 of the performance apparatus 11 gives a sound source unit 31 of a musical instrument unit 19 an instruction (note-on event) to generate a musical tone. CPU 21 generates a note-on event indicating a sound-generation timing represented by a time when an acceleration-sensor value of the acceleration sensor 23 exceeds a first predetermined value and thereafter has decreased to a value less than a second threshold value β, which is less than a first threshold value α, and gives the musical instrument unit 19 the generated note-on event to generate a musical tone.

A photographic print vending apparatus is provided which comprises a media accepting unit which accepts a recording medium having photographic image information stored thereon. An image information reader reads the image information from the recording medium, and a plurality of printers print images based on image data from a processor connected to the image information reader and an advertisement information storage unit. When an advertisement printing mode is set, the processor reads the advertisement information from the advertisement information storage unit, synthesizes the read advertisement information and the image information read by the image information reader, and supplies the synthesized information to the printers as image data.

A titanium alloy includes 15 to 27 atomic % (at %) of tantalum (Ta) and 0 to 8 at % of tin (Sn), the balance being titanium (Ti) and unavoidable impurities, when the entire amount of the titanium alloy is taken as 100 at %. Therefore, the titanium alloy provided has characteristics suitable for medical device materials, biocompatible materials, etc.
摘要:
A wireless communication system includes a first wireless communication apparatus, which includes a plurality of transmission antennas and transmits signals in an MIMO scheme, and a second wireless communication apparatus, which receives the signals. The first wireless communication apparatus performs the same frequency allocation for transmission antennas from which the same data is transmitted in case that transmission is performed in a rank less than the number of transmission antennas.
