    • The local oscillation circuit in accordance with the present invention is characterized as follows. The collector of an oscillation transistor is grounded for atlernating current. A series resonance circuit consisting of a variable capacitance diode and a resonator is connected to the base of the oscillation transistor. The other end of the series resonance circuit is grounded for alternating current. The emitter of the oscillation transistor is connected to the collector of an amplifying transistor. The emitter is grounded through a capacitor that removes or reduces the a.c. component and passes the d.c. component. An oscillation signal taken from the emitter of the oscillation transistor is fed to the base of the amplifier transistor. A local oscillation output signal is taken from the collector of the amplifier transistor, and bias potential to the amplifier transistor is impressed from the power source to the base of the amplifier transistor. With this arrangement, the current in the oscillation transistor is stabilized, even with a change in the d.c. control voltage supplied to the resonance circuit, to improve the reliability and performance of the circuit.

    • A Rankine cycle includes an waste-heat recovery device that is configured to exchange heat between cooling water coming out from an engine and exhaust gas exhausted from the engine, a heat exchanger including an evaporator through which the cooling water coming out from the engine flows to recover waste-heat of the engine to refrigerant, and a superheater through which the cooling water coming out from the waste-heat recovery device flows to recover the waste-heat of the engine to the refrigerant, an expander that is configured to generate power using the refrigerant coming out from the heat exchanger, a condenser that is configured to condense the refrigerant coming out from the expander, and a refrigerant pump that is configured to supply the refrigerant coming out from the condenser to the heat exchanger by being driven by the expander. The cooling water coming out from the superheater is returned to the engine after being joined with the cooling water coming out from the evaporator.
