摘要： A length of a melamine foamed block to be accommodated in an ink tank housing as measured in the longitudinal direction is dimensioned to be larger than a length of the ink tank housing as measured in the longitudinal direction. Thus, while the foamed block is accommodated in the ink tank housing, it is compressed in the direction orienting toward an ink feeding port from which ink is fed to a printing head, i.e., in the ink feeding direction. Consequently, the ink retaining force induced by the capillary force is not intensified in the compressing direction of the melamine foamed block, resulting in an ink feeding capability of the printing head being improved. On the contrary, the ink retaining force effective at a right angle relative to the compressing direction of the melamine foamed block is intensified.

摘要翻译： 沿长度方向测量的容纳在墨罐壳体中的三聚氰胺泡沫块的长度的尺寸设定为大于沿纵向测量的墨罐壳体的长度。 因此，当发泡块被容纳在墨盒壳体中时，它被朝着朝向从墨水供给到打印头，即在供墨方向上的供墨口的方向上被压缩。 因此，毛细管力引起的墨水保持力在三聚氰胺泡沫块的压缩方向上没有增强，导致打印头的供墨能力得到改善。 相反，加强了相对于三聚氰胺发泡块的压缩方向成直角有效的油墨保持力。

摘要： In order to detect a plurality of framing bit sequences for establishing synchronization at a receiver in a digital communications system, first and second counters are rapidly reset in order to establish the synchronization as early as possible. A comparator receives a bit stream transmitted and a desired bit sequence for use in detecting the framing bit, and compares the desired bit sequence with part of the bit stream and issues a coincidence signal in the event that the desired bit sequence coincides with the part of the bit stream. The first counter is coupled to receive the coincidence signal, and allows an output indicating the establishment of the synchronization to issue in the event that it reaches a predetermined number of correct coincidence signals. The second counter counts up the number of occurrences of the output of a clock counter, and resets itself and the first counter when reaching a predetermine number of occurrences of a pseudo-coincidence signal.

摘要： A liquid ejection recording head comprises a supporting substrate having energy generating elements thereon, a lid member and a wall portion between the supporting substrate and the lid member. The wall portion includes a surrounding wall that forms a liquid chamber between the substrate and the lid member and an enclosing wall disposed around the surrounding wall that provides a gap between the surrounding and enclosing walls, which gap is in communication with the exterior of the head through an opening in the enclosing wall. The wall portion also includes a plurality of substantially similar, parallel wall members, a first plurality of which forms an array of flow paths from the liquid chamber to orifices for discharging liquid when the energy generating elements are actuated and a second plurality of which forms open channels not in communication with the liquid chamber but in communication with the exterior of the recording head. The wall portion enables a secure bond to be made with the lid member, since it presents sufficient contact area for bonding, while the open channels and gap prevent air from being trapped between the lid member and substrate during assembly of the head.
