Abstract: A power generation apparatus includes a dielectric, a movable member being opposed to the dielectric with a predetermined distance, and an electret and an opposing electrode that are formed on the surface of the movable member facing the dielectric so as to generate a fringe electric field penetrating the dielectric between the two electrodes. When the volume occupancy of the dielectric between the electret and the opposing electrode varies in accordance with a displacement of the movable member, the power generation apparatus outputs the electric charge induced in the opposing electrode as electric current.

Abstract: A thermal print head includes a heat-generating substrate, a resistor layer, a conductive layer, a first substrate, a second substrate, and a third substrate. The heat-generating substrate includes a heat-generating substrate obverse face and a heat-generating substrate reverse face that are spaced apart from each other in a thickness direction. The resistor layer is supported by the heat-generating substrate. The conductive layer is supported by the heat-generating substrate, and electrically connected to the resistor layer. The first substrate is located upstream of the heat-generating substrate in a sub-scanning direction. The second substrate is located upstream of the first substrate in the sub-scanning direction. The third substrate is bonded to the first substrate and the second substrate and higher in flexibility than the first substrate.

Abstract: A thermal printhead includes a substrate, a resistor layer with heat generation portions supported by the substrate and aligned in a primary scanning direction, a wiring layer supported by the substrate to form a conductive path to the heat generation portions, an insulating layer interposed between the substrate and the resistor layer, and a reflection layer located opposite to the heat generation portions with respect to the insulating layer. The reflection layer overlaps with the heat generation portions as viewed in a thickness direction of the heat generation portions and has a greater heat reflectivity than the insulating layer.
