    • An ink jet printhead is disclosed which has a heater plate containing the heating elements and driving circuitry means monolithographically formed on one surface thereof and the ink flow directing channel structure is formed on the heater plate using a layer of patternable material, so that all critical alignments are done directly on the heater plate. In one embodiment, the patternable material is a photosensitive polymer which is exposed using a mask to define the channel and reservoir pattern, which is then developed and cured. After curing, the patterned channel structure is polished to provide a smooth coplanar surface and a cover plate with an aperture therein is aligned with a loose tolerance to the channel structure and bonded thereto to complete the printhead. The aperture serves as both ink inlet and a portion of the ink reservoir. The channels are open at one end and serve as the droplet ejecting nozzles, while the other ends are connected to the reservoir. In one embodiment, the cover plate is transparent and the channel structure material is polyimide or polyarylene ether ketone.

    • A cost effective method of fabricating a large array or pagewidth silicon device having high resolution is disclosed. The pagewidth device is assembled by abutting silicon device sub-units such as image sensors or thermal ink jet printheads. For printheads, the sub-units are fully operational small printheads comprising an ink flow directing channel plate and a heating element plate which are bonded together. A plurality of individual printhead sub-units are obtained by dicing aligned and bonded channel wafers and heating element wafers. The abutting edges of the printhead sub-units are diced in such a manner that the resulting kerfs have vertical to inwardly directed sides which enable high tolerance linear abutment of adjacent sub-units. Alternatively, the wafer surface containing the heating elements is first anisotropically etched to form small V-grooves, one wall of which protects against microcracking during the dicing operation. The other wall of the V-groove is obliterated by the slanted dicing blade.

    • A thermal ink jet printhead and method of batch production thereof is disclosed. Each printhead has a plurality of nozzles in a stepped nozzle face that are obtained by a two step dicing operation. The printheads being formed by aligning and bonding an anisotropically etched silicon wafer containing a plurality of sets of channel grooves to a silicon wafer containing a plurality of linear arrays of heating elements and addressing electrodes over which a thick film layer is deposited and photopatterned to expose the heating elements and electrode terminals and to remove the areas parallel to and a predetermined distanace from the heating element arrays, thus photodelineating the portion of the thick film layer between the heating elements and the nozzles. The mated wafer sandwiches the thick film layer, and first dicing cutting severs the etch wafer and notches the wafer with the heating elements, forming a nozzle face containing the nozzle. The first dicing cut is made at a location where the thick film layer has been etch removed, thus eliminating the need to dice it, thereby preventing the formation of burrs which affect droplet directionality.
    • 公开了一种热喷墨打印头及其批量生产方法。 每个打印头具有通过两步切割操作获得的阶梯式喷嘴面中的多个喷嘴。 打印头通过将包含多组通道槽的各向异性蚀刻的硅晶片对准和结合到包含加热元件和寻址电极的多个线性阵列的硅晶片上而形成,在该晶片上沉积厚膜层并曝光 加热元件和电极端子,并且去除与加热元件阵列平行的预定距离和预定距离的区域,从而对加热元件和喷嘴之间的厚膜层的部分进行光线测量。 配合的晶片夹着厚膜层,第一切割切割切割蚀刻晶片并用加热元件切割晶片,形成包含喷嘴的喷嘴面。 第一切割切口是在去除了厚膜层的位置处进行的,因此不需要将其切割,从而防止形成影响液滴方向性的毛刺。

    • A cleaning apparatus for a recording head in a magnetographic printing device of the type having a movable magnetic imaging tape in endless belt form is disclosed. The apparatus is especially effective for cleaning thermal printheads for thermoremanent magnetic imaging systems, and comprises a cleaning member adapted for reciprocal movement into and out of a nip formed by the magnetic tape and the printhead. In one embodiment, the cleaning member is a flexible substrate attached at one end to a rotatably mounted spool. The substrate is wound on the spool with the loose end resting on a guide plate and confronting the nip. The spool is periodically rotated to drive the substrate through the nip while the tape is moving and then is rotated in the opposite direction to rewind the substrate and withdraw it from the nip. In another embodiment, the cleaning member is a flexible substrate which is maintained in a planar configuration by parallel guide plates. A tractor wheel drive reciprocally moves the cleaning member into and out of the nip. The cleaning member may be a non-conductive, woven material having open spaces therein or a two layered composite having a non-conductive screen on one side to contact the tape and a carpet of short bristles on the other side to clean the printhead. Optionally, lateral movement of the cleaning member is provided after it enters the nip and the heating elements of the printhead may be momentarily energized to heat and soften the toner accumulated on the printhead to enhance the cleaning efficiency of the apparatus.
