摘要: An ink droplet sensing means for detecting whether or not droplets are impinging on record media during ink jet printing operations. A synthetic foil having a metal layer is placed over a counter electrode having a rough surface on one side and a voltage is then applied to the electrode and the metal layer. Ink droplets impinging on the foil momentarily deflect the foil and cause a change in capacity which in turn causes a voltage change at the electrode. The voltage change is coupled through a capacitor and an amplifier and through recognition logic for evaluation of the signals.

摘要: An ink jet printer includes a print head having a plurality of piezoelectric driving elements selectively energizable to cause ejection of droplets of ink through nozzles in a nozzle plate. Ink is supplied to the print head from an ink reservoir which is connected to a bellows device. The ink reservoir and the bellows device together form an air-tight container. The bellows device has a resilient form of construction so as to tend to increase the volume of the container. As a result, an appropriate underpressure is maintained in respect of the ink in the nozzles, such underpressure being necessary to prevent ink escaping from the nozzles under quiescent conditions. In operation, the bellows device progressively collapses so as to reduce the rate at which the underpressure increases as ink is ejected, thereby prolonging the period for which the underpressure is maintained within a desired operating range. In two other embodiments, the reservoir is enclosed by a piston or a membrane, both biased against collapse by a compression spring. In yet another embodiment, underpressure within the reservoir is maintained by a capillary tube that at one end is immersed in ink and at the other end is open to the exterior of the printer.
摘要翻译: 喷墨打印机包括具有多个压电驱动元件的打印头,所述多个压电驱动元件选择性地激励以通过喷嘴板中的喷嘴喷射墨滴。 墨水从连接到波纹管装置的墨水储存器供应到打印头。 墨水储存器和波纹管装置一起形成气密容器。 波纹管装置具有弹性形式的结构,从而倾向于增加容器的体积。 结果,对喷嘴中的油墨保持适当的负压,这样的负压是防止在静止条件下油墨从喷嘴逸出的必要的。 在操作中,波纹管装置逐渐塌缩,以便降低墨水喷射时负压增加的速率,从而将负压保持在所需操作范围内的时间延长。 在另外两个实施例中,储存器由活塞或膜封闭,两者均被压缩弹簧偏压而压缩。 在另一个实施例中,储存器内的负压通过毛细管来维持,该毛细管在一端浸入墨水中,而另一端对打印机的外部是开放的。

摘要: A device and a method for determining the current position of a rotor, particularly the angle of rotation of the rotor, of an electric motor, wherein said device determines the current position of the rotor using the fluctuations of the armature current or the armature voltage of the electric motor. The fluctuations of the armature current or the armature voltage are separated from the fluctuations of the motor current or the motor voltage with the help of an amplifier unit dependent on a controllable offset value. The offset value is changed according to the motor current or the motor voltage. By virtue of the device and the method, the fluctuations of the armature current or the armature voltage can be separated from the fluctuations of the motor current or the motor voltage over the full measurement range of the motor current or the motor voltage.

摘要: The invention relates to a method for treatment of Hypertrophic Obstructive Cardiomyopathy (HOCM) in a human heart, wherein a laser catheter means is introduced into a patient's body and advanced into a heart cavity and directed towards a hypertrophied region of the heart. Ventricular outflow tract obstructions may be substantially reduced or even abolished when laser light is applied to the hypertrophied tissue so as to produce a coagulation necrosis inside the hypertrophied septal wall.
