摘要： A memory circuit with a word line driver and control circuitry is disclosed. The word line driver receives a first voltage reference signal, a second voltage reference signal, and an input signal. The word line driver has an output coupled to a word line. The control circuitry is configured to deselect the word line by applying the input signal to the input of the word line driver. For example, in a program operation the word line is deselected to indicate that the word line is not programmed, and another word line is selected to be programmed. During an operation in which the word line is deselected and another word line is selected, the word line discharges through both of a first p-type transistor and a first n-type transistor of the word line driver.

摘要： An electric saw device having two saw blades being arranged for allowing the two saw blades to be driven to rotate in opposite directions. The two saw blades are respectively formed with circular grooves on their inner surfaces at positions corresponding to each other while enabling the centers of the two circular grooves to aligned with the rotation axes of corresponding saw blades. The electric saw device has a plurality of steel balls, each being sandwiched between the two saw blades while insetting into the circular grooves simultaneously, by that the saw blades are separated from each other by a specific interval. Accordingly, when the two saw blades are rotating in opposite direction, each of the steel balls is acting as a roller bearing for maintaining the two saw blades to be properly separated from each other, and thus preventing the two saw blades from overheating and softened by friction.
摘要翻译：具有两个锯片的电锯装置被布置成允许两个锯片被驱动以相反的方向旋转。两个锯片在它们的内表面上分别形成有相互对应的位置的圆形槽，同时使得两个圆形槽的中心能够与相应锯片的旋转轴线对齐。电锯装置具有多个钢球，每个钢球同时插入到两个锯片之间，由此锯片彼此间隔一定间隔。因此，当两个锯片沿相反方向旋转时，每个钢球都起到保持两个锯片彼此适当分离的滚子轴承的作用，从而防止两个锯片过热和软化摩擦。
