摘要： The moving carbon nanotube heat sink includes a heat transfer belt comprised of highly thermally efficient carbon nanotubes. Laterally disposed cooling fins extend away from a top surface of the belt. The belt is slidingly disposed over a C-shaped channel made of metal or other suitable material that is mechanically and/or chemically connected to a top surface of an electronic chip. Belt movement may be powered and guided by a plurality of rollers. The cooling occurs primarily as a result of conduction and convection heat transfer modes.

摘要： A hot beverage cup and sleeve bring together two modes of heat transfer, conduction and radiation. The sleeve has an inner face with a plurality of high reflectivity surfaces for radiating heat back to the cup. The sleeve also has a plurality of insulating members for containing insulating air. Each of the insulating members is positioned to space the high reflectivity surfaces away from the cup. A low emissivity film can be adhered to the cup without touching the insulating members. The film can also be attached to the sleeve facing but spaced from the high reflectivity surfaces. This cup and sleeve arrangements minimize thermal contact and reduce heat transfer. Thus, the hot beverage cup and sleeve protect a person's hand as well as extend the time of keeping the beverage hot.

摘要： The present invention is embodied in an actuator arm which is mounted to a primary actuator. The primary actuator positions the actuator arm, with a read/write head mounted to the actuator arm, across a data storage disk. The actuator arm comprises an inboard portion, an outboard portion and a pair of bimorph actuators. The inboard portion has a longitudinal axis and is attached to the primary actuator. The outboard portion has the read/write head mounted onto it. The pair of bimorph actuators are deflectable together in a common direction and are connected between the inboard and the outboard portions. Upon deflection of the bimorph actuators in the same direction, the outboard portion is translated along an at least nearly straight line transverse to the longitudinal axis of the inboard portion. This transverse motion allows the read/write head to be kept substantially within a plane parallel to the surface of the data storage disk, preventing damage caused by possible contact between slider and the disk surface from rolling the slider due to out-of-plane motions. Further, the use of bimorph actuators provide increased displacements of the read/write head. Also, since the head displacement is not a function of microactuator's position along the actuator arm, the actuator arm can be shorter, allowing for use in compact disk drives.
摘要翻译：本发明体现在安装到主致动器上的致动器臂中。主执行器将执行器臂定位在读/写头安装到致动器臂上的数据存储盘上。致动器臂包括内侧部分，外侧部分和一对双压电晶片致动器。内侧部分具有纵向轴线并且附接到主致动器。外侧部分具有安装在其上的读/写头。一对双压电晶片致动器在共同的方向上可偏转在一起，并且连接在内侧和外侧部分之间。当双向压电致动器在相同方向上偏转时，外侧部分沿着横向于内侧部分的纵向轴线的至少几乎直线平移。这种横向运动允许读/写头基本上保持在与数据存储盘的表面平行的平面内，防止由于平面外的运动而使滑块和盘表面之间的可能的接触滚动滑块所引起的损坏。此外，双压电晶片致动器的使用提供了读/写头的增加的位移。此外，由于头位移不是微致动器沿着致动器臂的位置的函数，所以致动器臂可以更短，允许在紧凑的磁盘驱动器中使用。

摘要： A system for positioning a transducing head in a disc drive device over a selected track of a rotatable disc includes an actuator arm which is rotatable about an axis, a head suspension mechanism connected to the actuator arm, and a slider carrying a transducing head and supported by the head suspension mechanism. A low resolution motor moves the actuator arm about the axis to effect coarse movement of the head between tracks of the disc. A piezoelectric element is embedded in the actuator arm to distort the arm to effect fine positioning of the head. Control circuitry distributes electrical signals to the low resolution motor and the piezoelectric element to selectively control movement thereof. The piezoelectric element is embedded in the actuator arm by removing a predetermined amount of material from the actuator arm and bonding the piezoelectric element in the resulting space it the actuator arm.

摘要： The acoustic leak detection system with environmental noise isolation provides for the acoustic detection of leaks in a pipe while minimizing interference from external or environmental noise. The acoustic leak detection system includes a hollow shell adapted for positioning about the pipe to be inspected. A pair of gaskets are circumferentially secured to the inner surface of the hollow shell so that the pair of gaskets bear against the outer surface of the pipe to form an acoustically isolated region defined between the pipe, the pair of gaskets and the inner surface of the hollow shell. An acoustic sensor, microphone or the like is mounted on the hollow shell within the acoustically isolated region for detecting any acoustic signals; i.e., the sound produced by a leak in the pipe within the acoustically isolated region. Upon detection of a leak, an alert signal is generated.

摘要： The piezoelectric damping device is a passive piezoelectric vibration suppression and damping device for reducing amplitude of vibration in structures. The piezoelectric damping device includes a magnetic layer having opposed inner and outer faces, with the inner face thereof being adapted for releasable magnetic attachment to a vibrating structure, such as a metallic pipe, for example. A piezoelectric layer is secured to the outer face of the magnetic layer. Preferably, an electrically insulating layer is sandwiched between the magnetic layer and the piezoelectric layer. The electrically insulating layer is preferably an electrically insulating adhesive. An electrical shunting circuit is in electrical communication with the piezoelectric layer, such that vibration in the piezoelectric layer caused by the vibrating structure generates electrical energy, which is then dissipated by the electrical shunting circuit, thus damping vibration in the vibrating structure.
