    摘要: An ultrasonic motor achieves uniform contact between a vibrating body and a moving body and features high output transfer efficiency and high reliability. The manufacturing process for the moving body can be simplified and the moving body made lighter by making the moving body of a carbon fiber reinforced resin composite material reinforced by at least carbon fiber, and constructing the moving body with a both-side supported or single-side supported beam construction. Elasticity according to the pressure of the ultrasonic motor can be imparted in the direction of pressure of the moving body. Thus, the undulations in the contact surface of the vibrating body and the moving body can be absorbed, stable, uniform contact can be assured, and long-term maintenance of a stable friction condition can be achieved.

    摘要: A method of driving an ultrasonic motor having a rotation body (6) which is rotated by travelling waves generated in a vibrator body (3), whereby the drive frequency of the motor is controlled in accordance with the value of an operating parameter such as phase difference between drive current and voltage, such as to maintain the drive frequency at a value which is lower than the antiresonance frequency of the vibrator body (3) and higher than a highest resonance frequency of the vibrator body (3) in a hysteresis loop exhibited by a resonance frequency characteristic of the vibrator body (3). Continuous stable operation is attained, irrespective of the effects of temperature and load changes upon the motor operating characteristics.

    摘要: To provide a light emitting device easy to produce and extracting light to its outside with high efficiency, the light-emitting device 70 of the present invention includes an insulating base 10; a light-emitting element 1 mounted on a side of the base 10; and a protection element 2 mounted on the side and protecting the light-emitting element 1. The element 2 is covered with a light-reflecting filler-containing resin 5, which is prepared by causing a flexible silicone resin to contain, before being cured, light-reflecting or light-scattering fillers 5a having a particle diameter larger than the wavelength of light emitted by the element 1. This causes light emitted from the element 1 to be reflected by the resin 5, instead of being absorbed by the element 2, so that such light is released to the outside of the light-emitting device 70. This allows the device 70 to extract light to the outside with high efficiency, and also allows for easy formation of the resin 5 having a desired pattern and position.

    摘要: A light emitting device includes a light emitting element having an emission peak wavelength of 350 nm-420 nm and a phosphor absorbing light from this light emitting element and emitting fluorescence having a different emission peak wavelength. The phosphor is formed of a semiconductor material that allows the emission peak wavelength to be controlled by transition across the bandgap, and is configured with four or more fluorescences having different emission peak wavelengths. Thus, it is possible to provide a light emitting device which has a relatively simple structure to keep high theoretical efficiency limit and achieves good general color rendering index (Ra) and special color rendering index (R9).

    摘要: A wafer with a reversed domain is prepared for two piezoelectric single crystal plates and of about the same thickness by using direct bonding without any adhesive. Driving electrodes are formed on two principal planes of the wafer with a reversed domain to provide a piezoelectric resonator. A piezoelectric resonator having the structure with a reversed polarization and using odd-order vibration modes vibrating with a fundamental wave has a wavelength of a thickness thereof and suppresses scattering of the thickness of the domains with a reversed polarization. In the direct bonding, the axes of the spontaneous polarization of the two piezoelectric single crystal plates are reverse to each other and crystalline axes other than the axes of polarization are shifted intentionally by an angle other than zero. Thus, spurious modes are suppressed in a simple way.
