    摘要： A head drive control unit generates and outputs a pulse formed of a first expansion waveform element to expand individual liquid chambers, a first contraction waveform element to contract the individual liquid chambers, a second expansion waveform element to expand the individual liquid chambers, and a second contraction waveform element to return the individual liquid chambers that have repeatedly expanded and contracted to an initial state. The first contraction waveform element serves as a waveform element that contracts the individual liquid chambers at a timing of resonance with a change in a pressure in the individual liquid chambers due to the first expansion waveform element. The second contraction waveform element serves as a waveform element that suppresses the change in the pressure in the individual liquid chambers.

    摘要： In a broadband access network, calls can be kept active even when a telephone network fails. A voice gateway function captures callee telephone number information sent from a caller subscriber telephone to the telephone network and, when the telephone network fails, keeps the call active by retaining the connection between the caller and the callee. Furthermore, when the telephone network fails, the operation mode of the voice gateway and all ONTs is switched from an H.248 gateway mode to an SIP softswitch mode, allowing the voice gateway function to relay communication packets between ONTs and new call connections to be made in the broadband access network.

    摘要： A liquid ejection head includes a plurality of orifices, a plurality of chambers in communication with the orifices, a plurality of fluid resistance portions in communication with the chambers, a plurality of liquid passages each including at least one of the chambers and at least one of the fluid resistance portions, a plurality of passage groups each including adjacent ones of the liquid passages, and a plurality of first partitions and a plurality of second partitions. The orifices eject droplets of liquid. The fluid resistance portions each are narrower than the chambers. Each of the first partitions, provided with a void, separates adjacent ones of the liquid passages. Each of the second partitions, which is not provided with the void, separates adjacent ones of the passage groups. The liquid ejection head is capable of recording a high-quality image with an increased density of liquid passages and nozzle orifices.
