摘要： A door hinge with automatic returning means composed of; a male hinge member (1), a female hinge member (2), an inner sleeve (3), a transmission rod (4), main spring (5), a driving element (6), a buffer spring (7) and a retainer (8), in which, the male and female hinge members will take an angle of rotation in anti-clockwise when the door is proceeding to its open position, and in turn to effect the driving element and transmission rod to rotate in synchronized operation respectively. When the movement for driving element is being effected through a helical motion of external/internal thread engagement, and with the restraint imposed onto this element by outer sleeve of female hinge member, this element will move upward to press the main spring to retract. When door is released by operator it also released the pressure on main spring, and this released pressure will push the driving element to move downward and in turn to rotate the transmission rod as well as the male hinge member in clockwise direction for an equivalent amount of angle unit the door returned to its closed position automatically.

摘要： The present invention provides a support for temporary bonding a workpiece such as a thick device wafer. The support comprises a carrier having a supporting surface and an isolation film. A first side of the isolation film is bonded to the supporting surface with a peeling strength of from 0.01 to 50.0 g/cm. The invention also provides a method of using the support to e.g. grind the workpiece in making thinned products such as thin silicon wafer, optical lens, thin LCD glass, and thin rock crystal wafer, among others.

摘要： A multiple-valued literal circuit is implemented with resonant tunneling diodes (RTD). A number of RTD sections are connected in series with a current source. Current is tapped by a current bleeder between every two adjacent RTD sections. The current bleeders are turned on at different levels of input voltage, which is applied at the joint between the current source and the RTD sections. When the voltage reaches a certain threshold level, the current bleeder with the highest threshold voltage is turned on and taps the most current from the current source, depleting the current from other current bleeders with lower threshold voltages. Thus only one dominant current is tapped from the current source. The literal circuit can be used for multiple-valued decoders, multiplexers, demultiplexers and other multiple-valued digital systems.
摘要翻译：谐振隧道二极管（RTD）实现了多值文字电路。许多RTD部分与电流源串联连接。每两个相邻RTD部分之间的电流泄漏电流被分流。电流放电器以不同的输入电压水平开启，这些电压源被施加在电流源和RTD部分之间的接头处。当电压达到一定的阈值电平时，具有最高阈值电压的电流放电器导通，并从电流源抽出最大电流，从较低阈值电压的其他电流泄放器中消耗电流。因此，只有一个主流电流从当前源被轻敲。文字电路可用于多值解码器，多路复用器，解复用器和其他多值数字系统。
