摘要： An improved structure for rotational support for a heat-dissipation fan is disclosed, comprising a hollow ceramic bearing passing through and concentric with the fan rotor and rotating with said rotor, a hollow ceramic support bearing fixedly mounted to the base of the fan, and a hollow or solid ceramic axle tube passing through the inside of said bearing and rotating freely to reduce friction and allow high-speed rotation. The exterior surface of said bearing is ground or otherwise formed to provide better connection with the rotor, while the interior of the bearing and exterior of the axle tube are further processed to reduce contact area therebetween to reduce rotation friction. This improved structure has achieved reduced friction, reduced noise, reduced power consumption, longer life and higher rotational speed.

摘要： An improved structure of a laminated piezo ceramic transformer device comprising multiple thin square piezo ceramic plate, mesh-printing with electrode material in three different patterns, a circular internal electrode, a circular solid and or dotted line supporting structure and a connecting electrode. This improved structure has better plate support and even thickness to reduce known green body crack while laminating plate and reduce sintered parts micro-crack. Since expensive electrode material will accelerate ceramic crystallization resulting a lower sintering temperature and lower production cost, the circular solid and or dotted line supporting structure will maximize electrode material coverage but with less amount. In addition, applying a thin layer of bond, glue or paint to the piezo ceramic transformer will reduce insulation degradation caused by high moisture, avoid electrode oxidation and reduce noise level caused by inherent mechanical vibration. These improved structure and process provide a better yield rate, lower production cost and broader mobile application.
摘要翻译：包括多个薄方形压电陶瓷板的叠层压电陶瓷变压器装置的改进结构，具有三种不同图案的电极材料的网状印刷，圆形内部电极，圆形固体或虚线支撑结构和连接电极。这种改进的结构具有更好的板支撑，甚至厚度，以减少已知的生坯裂纹同时层压板和减少烧结部分微裂纹。由于昂贵的电极材料将加速陶瓷结晶，导致较低的烧结温度和较低的生产成本，圆形的固体和/或虚线支撑结构将使电极材料的覆盖范围最大化，但具有较少的量。另外，在压电陶瓷变压器上施加一层薄薄的粘合剂，胶水或涂料会降低高湿度引起的绝缘降解，避免电极氧化，降低固有机械振动引起的噪音。这些改进的结构和工艺提供了更好的成品率，更低的生产成本和更广泛的移动应用。
