摘要： A monitoring system for detection of defects in an optical fiber coating during production of the fiber has first and second beam generating means which produce planar coherent beams which cross each other at the fiber passing through the system creating one or more diffraction patterns. A first plurality of photodetectors are mounted in a mount, the front face of which is impinged by the planar diffraction pattern, and a second plurality of photodetectors is similarly mounted in position below the impinging pattern. A defect in the fiber coating, regardless of shape or orientation, will cause the pattern or patterns to be tilted or shifted upward, downward, or planarly tilted to impinge one or more of the photodiodes which, as a result, generates a signal which is applied to a comparator and control circuit.

摘要： An ink jet (10) apparatus and method provides high-resolution gray scale printing by providing multiple PZT drive waveforms (100, 110, 120), each having a spectral energy distribution that excites a different modal resonance of ink in an ink jet print head orifice (14). By selecting the particular drive waveform that concentrates spectral energy at frequencies associated with a desired oscillation mode and that suppresses energy at the other oscillation modes, an ink drop (170, 180, 190) is ejected that has a diameter proportional to a center excursion size of the selected meniscus surface oscillation mode. The center excursion size of high order oscillation modes is substantially smaller than the orifice diameter, thereby causing ejection of ink drops smaller than the orifice diameter. Conventional orifice manufacturing techniques may be used because a specific orifice diameter is not required. Jetting reliability and contaminant susceptibility are, thereby, improved by eliminating the need for an unconventionally small orifice. Changing a selected PZT drive waveform amplitude changes drop ejection velocity without changing drop volume. This invention, therefore, provides for selection of ejected ink drop volumes having substantially the same ejection velocity over a wide range of ejection repetition rates.
摘要翻译：喷墨（10）装置和方法通过提供多个PZT驱动波形（100,110,120）来提供高分辨率灰度级打印，每个PZT驱动波形具有频谱能量分布，其在喷墨打印头中激发墨的不同模态共振孔口（14）。通过选择将频谱能量集中在与期望振荡模式相关联的频率并且抑制其它振荡模式下的能量的特定驱动波形，喷射具有与中心偏移大小成比例的直径的墨滴（170,180,190）的所选弯液面表面振荡模式。高阶振荡模式的中心偏移大小基本上小于孔口直径，从而使墨滴喷射小于孔口直径。可以使用传统的孔口制造技术，因为不需要特定的孔直径。因此，通过消除对非常规小孔的需要，可以改善喷射可靠性和污染物敏感性。更改所选的PZT驱动波形幅度会改变下降喷射速度，而不会改变下降音量。因此，本发明提供了在广泛的喷射重复率范围内选择具有基本上相同喷射速度的喷射墨滴体积。

摘要： An improved striking device is provided as including a main post having two main longitudinal slots. An insert post having an outside diameter that is less than the inside diameter of the main post is provided. A striking surface is provided that is attached to an arm which in turn is attached to an arm housing. The arm housing has a first housing end and a second housing end. The arm housing is placed around the main post and the second housing end rests upon a support axle passing through the insert post. The first housing end includes a cam surface having two peaks located on opposite sides thereof and two valleys located on opposite sides thereof with each of the two valleys disposed between each of the two peaks. A cam follower is included which is retained in contact against the cam surface by a pair of springs. During rotation of the arm housing the cam follower cooperates with the cam surface of the arm housing to provide a first striking position and a second striking position that are each located one hundred and eighty degrees of rotation apart with respect to each other. As the arm housing rotates the cam surface extends the cam follower which is turn extends the pair of springs in proportion to the contour of the cam surface. If sufficient force is imparted to the striking surface, the arm housing is urged away from the first striking position, and indexes into the second striking position.

摘要： A printer accurately controls the passage of print media therethrough and maintains the print media taut as the print media passes through a printing zone while the media is printed by an ink jet printer. The print media sheet is preferably carried by a rotating drum in a first direction through the printing zone, with the drum being reversed to cause the exiting of the print media sheet from the printer. A pressure fixing or fusing apparatus may be positioned to flatten ink spots on the print media as the print media exits from the printer. The pressure fixing or fusing mechanism is preferably used in the case of a hot-melt or phase-change ink jet printer.

摘要： An air-assisted drop-on-demand ink jet head 10 has a single compartment ink chamber 14 and is designed for operation over a wide range of ink drop repetition rates, including extremely high repetition rates, such as twenty kilohertz. The components included in the ink jet head have natural resonance frequencies which are greater than the desired maximum drop generation frequency of the ink jet head. In addition, the natural frequency of each of the components of the ink jet head are sufficiently different from one another to prevent intercoupling. Ink is supplied to the ink chamber 14 via a supply inlet passageway 38 which has a cross-sectional area which is sized large enough to allow the supply of ink to the ink chamber. Yet, this area is small enough so that the natural frequencies of ink in the ink inlet do not significantly alter drop generating pressure pulses in the ink chamber 14.

摘要： A drop-on-demand ink jet print head (9) has an ink pressure chamber (22) coupled to a source of ink (11) and an ink drop ejecting orifice (103) with an ink drop ejection orifice outlet (14). An acoustic driver (36), in response to a drive signal (100), produces a pressure wave in the ink and causes the ink to pass outwardly through the ink drop ejecting orifice (103) and the ink jet ejection orifice outlet (14) of the ink jet print head (9). In accordance with the present invention, controlling the operation of the ink jet print head (9) with a particular drive signal reduces print quality degradation resulting from rectified diffusion, which is the growth of .air bubbles dissolved in the ink from the repeated application of pressure pulses to the ink residing within the ink pressure chamber (22) of the ink jet print head (9), such pressure pulses causing the application of pressures below ambient pressure. This method of controlling the operation of the ink jet print head (9) applies pressure below ambient pressure to the ink residing within the ink pressure chamber (22) of the ink jet print head (9) at magnitudes less than the threshold pressure magnitude that leads to the air bubble growth.

摘要： A ferroelectric relaxor ceramic actuator material, such as lead magnesium niobate ("PMN"), has high electromechanical conversion efficiency, exhibits wide operating and manufacturing temperature ranges, does not require permanent polarization, and provides useful mechanical activity with reduced electrical drive voltages. A PMN actuator (66) may be bonded to an actuator diaphragm (64) with a high temperature soldering or brazing process. PMN material also has a diffuse Curie point range in which the dielectric constant (40), "d" coefficient (32), and dielectric loss (42) characteristics all rise to a peak and then fall as the temperature increases. A phase-change ink-jet print head (50) employs a PMN actuator that is compounded with lead titanate ("PT") to increase the temperature (T.sub.M) at which the peak dielectric constant occurs. The print head is operated at a temperature beyond the peak where the PMN:PT actuator "d" coefficient decreases as the temperature increases such that an increase in ink-jet drop ejection velocity caused by reduced ink viscosity is compensated for by a corresponding reduction in mechanical activity. The PMN:PT actuator thereby relaxes the temperature regulation and heat spreading requirements of the phase-change ink-jet print head.
