Methods for treating cardiovascular and related diseases such as hypertrophy, hypertension, congestive heart failure, ischemia, ischemia reperfusion injuries in various organs, arrhythmia, and myocardial infarction, are described. A first emitter bias resistor for setting the emitter current of a first oscillation transistor in the first oscillation circuit is provided between the emitter of the first oscillation transistor and a second inductance element in the second oscillation circuit. A method of cementing in a subterranean formation comprises: introducing a cement composition into the subterranean formation, wherein the cement composition comprises: cement; water; and the surfactant; and allowing the cement composition to set. More preferably, heat radiating effect is given to a fourth passivation film 50 to make the EL element 203 to be enclosed by heat radiating layers. The controller may also be configured to adjust operation of the injection device based on the determination.
