    • Fluid discharge device and method for intermittently discharging and feeding fluid in a constant amount with high speed and high precision, the fluid exemplified by various kinds of liquids such as adhesives, solder paste, fluorescent materials, electrode materials, greases, paints, hot melts, chemicals, foods and the like in production processes in the fields of electronic components, household electrical appliances, displays, and the like. By providing a fluid supply device for supplying the fluid to two surfaces that are moved relative to each other along a direction of a gap, a continuous flow supplied from the fluid supply device is converted into an intermittent flow by utilizing a pressure change due to a change in the gap of the relatively moving surfaces, while the intermittent discharge amount per dot is controlled by the rotational speed of the fluid supply device.

    • In a conventional hard material insulator, reproduced sound can be tuned with use of characteristics of the material; however, various types of acoustic materials have specific high frequency characteristics, and thus their acoustic effects lack versatility, require compatible audio devices, and change with environment, musical genre, etc. To address this, a wind-bell member (resonant member) is arranged in parallel with a main propagation path of vibration transferred from an audio device to an insulator. Accordingly, a vibration system of a wind-bell having a tone determined by many factors such as a fundamental tone, harmonic tones, lingering sound, and fluctuation assists (enhances) high frequency vibration propagated from the audio device. As a result, due to the above assist action that is different in principle from a conventional type, acoustic characteristics such as a sense of localization, resolution, and a sense of transparency and scale a sound image can be dramatically improved.
    • 在传统的硬质材料绝缘体中,再现的声音可以利用材料的特性进行调节; 然而,各种类型的声学材料具有特定的高频特性,因此它们的声学效果缺乏通用性,需要兼容的音频设备,并且随环境,音乐类型等而改变。为了解决这个问题,风铃构件(共振构件) 与从音频装置传递到绝缘体的振动的主传播路径平行布置。 因此,具有由诸如基本色调,谐波音调,延迟声音和波动的许多因素确定的音调的风铃的振动系统有助于(增强)从音频装置传播的高频振动。 结果,由于上述原理上与常规类型不同的辅助动作,可以显着地提高诸如定位感,分辨率,透明度感和声音图像之类的声学特性。

    • A vacuum pump includes a plurality of rotors of different outer diameters accommodated in a housing so that a fluid transportation space is defined by the housing and the plural rotors. Rotary shafts are integrally formed with the respective rotors and a first motor, which is a high frequency motor, for driving the rotary shaft of the smaller diameter rotor as a driving shaft. A second motor, which is an AC servo motor or pulse motor, is provided for driving the other rotary shaft as a driven shaft. A rotation detecting device is provided adjacent each shaft for detecting rotating angles and/or rotating speeds of the first and second motors. Also provided is a fluid suction port and a fluid discharge port which are formed in the housing, and a control device for controlling rotation of the driven shaft based on data from the rotation detecting device so as to synchronize the rotation of the driven shaft driven by the second motor with that of the driving shaft driven by the first motor.
