摘要： A semiconductor substrate for a micro-fluid ejection head. The substrate includes a plurality of fluid ejection actuators disposed on the substrate. Each of the fluid ejection actuators includes a thin heater stack comprising a thin film heater and one or more protective layers adjacent the heater. The thin film heater is made of a tantalum-aluminum-nitride thin film material having a nano-crystalline structure consisting essentially of AlN, TaN, and TaAl alloys, and has a sheet resistance ranging from about 30 to about 100 ohms per square. The thin film material contains from about 30 to about 70 atomic % tantalum, from about 10 to about 40 atomic % aluminum and from about 5 to about 30 atomic % nitrogen.

摘要： In a liquid toner chamber (2) of a copier or printer a top plate (5) is moved upward and allowed to fall. The capacitance between the plates is used to define their separation and the time for the plates to move between predetermined locations is used to define the concentration of the liquid toner. This is accurate and inexpensive, while other measurement systems are not suitable to measure the high concentrations with which this invention functions.

摘要： Method and apparatus for use with dot-matrix printers to ensure that the maximum heat dissipation of critical components associated with the printhead is not exceeded during high density printing. The number of dots to be printed are determined by a counting technique which takes into consideration the thermal time constant of a critical component and the filter time constant of the power controlling or supplying components. These considerations allow the counting of output dots to be accurately transformed by a single dot power conversion factor into an accurate representation of the power in the critical components. The dot counts are divided into time intervals dependent upon a filter time constant and a thermal time constant. The dot counts are squared, summed and rooted to produce an RMS value which accurately predicts the power which produces the heat dissipation in the critical components.
摘要翻译：用于点阵式打印机的方法和装置，以确保在高密度打印期间不会超过与打印头相关的关键部件的最大散热。要打印的点数由考虑关键部件的热时间常数和功率控制或供给部件的过滤时间常数的计数技术决定。这些考虑允许通过单点功率转换因子将输出点的计数精确地转换为关键部件中的功率的精确表示。点计数被分为取决于滤波器时间常数和热时间常数的时间间隔。点计数是平方的，相加和加根，以产生RMS值，其精确地预测在关键部件中产生热耗散的功率。
