    Abstract: Disclosed is an electromechanical transducer film forming method including a surface modification process; an application process; and processes of drying, thermally decomposing, and crystallizing sol-gel solution applied to a portion of a surface of a first electrode. An electromechanical transducer film is formed on a desired pattern area on the surface of the first electrode by repeating the above processes. In the application process, each of dots of the sol-gel solution applied by the inkjet method drops onto both a first area inside the desired pattern area and a second area outside the desired pattern area. The first area is a hydrophilic area on the surface of the first electrode, and the second area is a hydrophobic area on the surface of the first electrode. The hydrophilic area and the hydrophobic area have been modified by the surface modification process.

    Abstract: A gate driver for driving a gate of a switching element Tr7 includes a driving part that drives the switching element according to a control signal and an active clamp circuit to clamp the voltage between the first and second main terminals of the switching element through the driving part. If a voltage applied between a first main terminal (drain) and a second main terminal (source) of the switching element exceeds a predetermined voltage, the active clamp circuit forcibly blocks a driving operation of the driving part from driving the switching element.
