    Abstract: The piezoelectric actuator drive control device has a controller, and executes an initialization process including an optimum phase difference acquisition process P1 and a phase difference inversion detection process P4 at a predetermined frequency. As a result, the optimum phase difference is updated each time the optimum phase difference acquisition process P1 runs to account for wear or temperature change from continuous operation. Furthermore, even if the phase difference between the drive signal and detection signal inverts during a drive frequency sweep due to variation in the vibration characteristic of the piezoelectric actuator, the phase difference inversion frequency and clamping frequency are reset each time the phase difference inversion detection process P4 is executed, thus preventing phase difference feedback control errors.

    Abstract: A driving circuit of a transmitting apparatus drives a piezoelectric element in a frequency band different from a resonance frequency at which a vibration system including the piezoelectric element resonates the most strongly. A driving circuit of a sound sensor drives the piezoelectric element for transmitting or receiving an acoustic wave in a frequency band different from a resonance frequency at which a vibration system including the piezoelectric element resonates the most strongly. Such a transmitting apparatus is mounted as a transmitting apparatus of a sound sensor to thereby realize the sound sensor with a small measurement error. The sound sensor is adopted for traveling control and steering control of an autonomous traveling vehicle to thereby enable an autonomous traveling vehicle capable of stopping in the vicinity of an obstacle to be realized.

  • Publication number: 20070046147
    Abstract: A driving circuit converts a direct current (DC) power supply voltage into an alternating current voltage of a predetermined frequency. The alternating current voltage is applied to an electrical element and boosted by a voltage resonant circuit of the electrical element. Based on a change in input voltage of the electrical element and a frequency component of a feedback voltage corresponding to the output voltage of the electrical element, an input voltage monitoring circuit generates an optimal control signal, and, using the optimal control signal, adjusts the DC power supply voltage such that a step-down chopper circuit is switched on and off at a predetermined duty ratio.

    Abstract: Broadband output high power pulsed flash lamps are useful in many applications, and when specifically optimized, can become an excellent source of ultraviolet (UV) light, which is particularly useful for photo-chemically-induced materials processing applications. Multiple factors involved with the production of high-energy light pulses can in certain cases adversely affect the ultraviolet lamp operation, thereby resulting in the development of micro cracks in lamp envelopes and subsequent limitation in lamp lifetime. Similar factors can be responsible for an increased absorption of UV radiation by lamp components and degradation of lamp efficiency. This invention describes new pulsed flash lamp designs that enable a new generation of high power and performance as required by, for example, many large-scale photo-processing applications.

    Abstract: In an organic light emitting display and a method for fabricating the same, a layout of respective pixels is changed in order to improve life span so that one pixel region having low luminous efficiency is increased. The organic light emitting display includes at least one pixel comprising sub pixels having a plurality of colors. A first sub pixel emission layer is formed over an entire surface of a pixel region. At least two second sub pixel emission layers are formed at the first sub pixel emission layer so as to have a closed curve. The layout of respective pixels is changed so as to increase an area of one sub pixel region having low luminous efficiency in order to improve the life span and aperture ratio of the organic light emitting display. In addition, during formation of an emission layer, the number of masks is reduced. Accordingly, the possibility of misalignment is reduced, thereby maximizing resolution, improving yield, and reducing manufacturing cost.
