To provide a high quality SAW device with enhanced productivity, wherein an outer face of a SAW chip mounted on a mounting substrate is covered with a heat-softened resin sheet and resin is filled on the SAW chip to form an airtight space below an IDT in the SAW device. Solids and liquids are subsequently removed from the metabolic reactor, separated and used as plant nutrients. A CCD camera records multiple points of light energy reflected from an integrated circuit to obtain a temperature measurement. It may include a snubber circuit having a diode that is SVT switched. One end of the magnetic pole piece is located adjacent to the bottom of the crucible base, so that the pole piece concentrates the dc field into the lower portion of the molten electrically conductive material. MOS transistors are then fabricated using the dielectric layers.
