A surface acoustic wave resonator and a SAW oscillator and an electronic apparatus including the resonator are to be provided. The semiconductor cooling device also includes a fan for cooling the condenser, a temperature detector disposed in proximity to the semiconductor element, and a controller for controlling the refrigerant pump and the fan. A gas powered turbine requires expanding gases to power the turbine blades. These InGaAlP-based layers are grown epitaxially by Organometallic Vapor-Phase Epitaxy on a GaAs substrate with a misorientation angle toward <111>A to improve the quality and surface morphology of the epilayer and performance in light emitting. The connector is electrically connected to the another terminal of each of the transparent conductive wires.
