A liquid ejection head includes a channel plate, a diaphragm member, and a piezoelectric member. The channel plate includes a separate liquid chamber, a fluid resistance portion, and a liquid introducing portion. The diaphragm member has a thin layer and a thick layer. The thin layer forms a wall face of each of the separate liquid chamber, the resistance portion, and the introducing portion and includes a vibration area facing the separate liquid chamber. The piezoelectric member is arranged to deform the vibration area and has a portion opposing the introducing portion. The thin layer has a thin portion forming the wall face of the introducing portion. The thick layer has a thick portion formed along the longitudinal direction of the separate liquid chamber on a first face opposite a second face opposing the introducing portion. In a plan view, the thin portion is divided by the thick portion.

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.

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.
摘要:
A first seal member is formed integrally on both surfaces of a first metal plate. The first seal member is integrally formed on a cooling surface of the first metal plate, except a region corresponding to a reaction surface facing an electrode reaction surface, and except regions of inlet buffers and outlet buffers. The first seal member has an expansion. The position of an end surface of the expansion substantially matches the position of a wall surface of the outermost groove of a coolant flow field to prevent the flow of a coolant around the electrode reaction surface.
