摘要： A recording head operable to apply an electric current to an electrically resistive layer, the head including two substrates each of which supports at least one electrode on one of opposite major surfaces thereof. At least one of the two substrates has an electrically insulating property and a lower wear resistance than the electrode(s) and each of the at least one substrate has a proximal portion, and a distal end portion extending from the proximal portion by a predetermined distance from the proximal portion for contact with said electrically resistive layer. The distal end portion has a thickness smaller than that of the proximal portion, as measured in a direction perpendicular to a direction of extension of the distal end portion. The two substrates are superposed on each other such that a non-electrode-supporting one of the opposite major surfaces of one of the two substrates faces an electrode-supporting one of the opposite major surfaces of the other substrate.

The substrate is formed of a material whose wear resistance is lower than that of the electrodes, and includes a proximal portion, and a thin-walled distal end portion (16) extending from the proximal portion for contact with an electrically resistive layer of a recording medium or an ink ribbon. The distal end portion has a constant thickness smaller than that of the proximal portion, and the substrate has a recessed portion formed in at least one of the opposite major surfaces such that the recessed portion at least partially defines the thickness of the distal end portion. A reinforcing layer (17) is disposed to reinforce the thin-walled distal end portion, such that at least a portion of the reinforcing layer is positioned in said recessed portion.

摘要： A micropipette is provided including at least one substrate, an inlet port through which a sample is delivered from the outside, a cavity to be poured and filled with the sample, an introduction hole, and an injection port for expelling the sample are formed on the at least one substrate. The substrate for forming the cavity is made of ceramics, a piezoelectric/electrostrictive element is provided for at least one wall surface of the substrate, and the sample moves as a laminar flow in the cavity. The volume of the cavity is changed by driving the piezoelectric/electrostrictive element to expell al certain amount of the sample in the cavity from the injection port. According to the micropipette, it is possible to form microspots with high accuracy and high speed. According to a dispenser including the micropipette, it is possible to efficiently dispense hundreds to ten thousands of different samples at one time and form microspots. Therefore, productivity is remarkably improved.

A differential adjusting tube is provided between the float cell and the reaction cell and includes a release valve for maintaining a specified pressure relationship between an internal pressure P2 of the float cell and an internal pressure P3 of the reaction cell. A driving circuit is provided to drive a pressurizing source of the liquid-drop discharge device and is connected to a control unit. The control unit is connected to a pressure sensor, which detects the internal pressure of the reaction cell and the release valve.
