In a method for fabricating a nanowire thermoelectric device, a first electrode pattern is formed on a substrate, wherein the first electrode pattern includes bottom electrodes and a first set of connections which connects the bottom electrodes to form first and second groups of electrically connected bottom electrodes. P-type nanowires and n-type nanowires are selectively formed on the substrate by selectively activating either the first group of electrically connected bottom electrodes and the second group. The p-type and n-type nanowires are then connected by top electrodes. A first set of holes in the substrate is formed to remove the first set of connections. A second set of holes to allow for electrical access to the bottom electrodes, and a second set of connections are formed, so as to result in an array of thermocouples connected to each other in parallel banks of series-connected thermocouples.

In a driving method of an ink-jet recording head, heat is generated by applying a drive signal to a heating element, and this heat is applied to ink to generate a bubble and discharge the ink through a discharge outlet. The drive signal comprises a first drive signal for storing foaming energy in the ink, and a second drive signal for generating a bubble in the ink. The second drive signal has a signal time shorter than the boundary foaming time at which foaming energy decreases in a case of performing foaming only by the second drive signal. The first drive signal is applied prior to the second drive signal in order to compensate for a decrease in foaming energy.

After a recessed portion 2 is formed in a first substrate made of single crystal silicon by crystal axis anisotropic etching, a peeling layer and a material of a fine tip which may be a noble metal or a noble metal alloy are formed. A second substrate is joined to the fine tip, and peeling is performed on the peeling layer, whereby the fine tip is formed on the second substrate.
