A liquid housing container in which a liquid to be supplied to a head can be stored may be attached to or detached from a holder, which is provided to a liquid ejecting device having the head for ejecting a liquid. In one aspect of the invention, a refractory layer is deposited onto a substrate having high aspect ratio contacts or vias formed thereon. The invention also relates to a terapeutical composition comprising a protein hydrolysate and a synthetic emulsifier andor a lipid based gain fraction having emulsifying properties. After the forming an insulating layer and before the etching the insulating layer, an average value of heights of a top surface of the insulating layer in the pixel region is larger than an average value of heights of a top surface of the insulating layer in the peripheral circuit region. The dual to single path converter is coupled to receive signals output by the dual path logic gate. The actuators extend from the poppet valves of each coupling member, and interlock to resist bending andor other lateral displacement caused by hydraulic fluid flow and turbulence in the coupling member bores and at the junction between the coupling members.
