摘要： A monitor adapted for mounting in an automobile headrest is provided. A screen structure of the monitor is pivotable about an upper edge thereof, such that the monitor occupies little volume within the headrest. A viewing angle of the screen structure is independently adjustable by a viewer, such that the viewer can continuously select the optimum viewing angle with changing conditions inside the automobile. The screen structure automatically retracts into a housing when struck. Thus, the monitor poses little risk of injury to passengers.
摘要翻译：提供适于安装在汽车头枕中的监视器。监视器的屏幕结构可围绕其上边缘枢转，使得监视器在头枕内占据很小的体积。屏幕结构的视角可由观看者独立调节，使得观看者可以随着汽车内部的变化条件连续地选择最佳视角。当打击时，屏幕结构自动缩回到外壳中。因此，监视器对乘客的伤害很小。

摘要： To prevent a furnace in a semiconductor process from temperature and gas excursion, a paddle and spike thermal couples arranged on the sidewall of the tube and adjacent to the heater, respectively, are connected to a temperature controller to regulate the heater, and a mass controller adjusts the gas flow injected to the tube. In the method, the spike thermal couple, peddle thermal couple and zero point of the mass flow controller are checked to maintain within a first and second temperature ranges and a first gas flow speed range, respectively, and after wafers are loaded and temperature is ramped up, the peddle thermal couple and mass flow controller are checked again to maintain within a third temperature range and second gas flow speed range.

摘要： A shaftless acoustic source is disclosed having a solenoid, a bullet and driving electronics. The bullet, which is positioned inside the solenoid's coil, can be accelerated by a magnetic force generated when a current pulse is applied to the coil. Acoustic energies are generated upon the impact of the bullet with an object, such as a borehole wall. This impact force can be described by the Hertzian Contact Theory (also referred to herein as Hertzian Theory) as a point of normal force with a time function similar to a half period sine function. A retraction device may be used to retract the bullet back into the solenoid after firing.
摘要翻译：公开了一种无轴声源，具有螺线管，子弹和驱动电子装置。位于螺线管线圈内的子弹可以通过当电流脉冲施加到线圈时产生的磁力加速。在物体（例如钻孔壁）的子弹撞击时产生声能。该冲击力可以通过赫兹式接触理论（本文也称为赫兹理论）描述为具有类似于半周期正弦函数的时间函数的法向力的点。退火装置可以用于在发射之后将子弹缩回到螺线管中。
