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.
摘要:
A frequency conversion apparatus for converting a high frequency signal into an intermediate frequency signal includes a mixer section for mixing a high frequency signal with a local oscillator signal so as to obtain an intermediate frequency signal, and an amplifier connected to the mixer section via a high frequency stopping circuit for supplying a constant direct current to the mixer section as a constant current source. A current flowing in the mixer section when the local oscillator signal is applied is kept substantially equal to a direct current flowing in the mixer section when no local oscillator signal is applied thereto. The amplifier is used for amplifying either the high frequency signal or the intermediate frequency signal, or both signals at the same time.
摘要:
A waste heat utilization apparatus is provided with a Rankine cycle and a power transmission mechanism that transmits power regenerated by an expander to an engine. The power transmission mechanism includes an expander clutch that interrupts or permits the transmission of the power from the expander to the engine. The expander includes a rotational speed sensor that detects a rotational speed of the expander. An increase in friction of the expander is detected on the basis of an increase in the rotational speed of the expander detected by the rotational speed sensor when the expander clutch is disconnected.

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.

The Rankine cycle (31) includes a refrigerant pump (32), a heat exchanger (36), an expander (37), and a condenser (38). The Rankine cycle (31) shares the condenser (38) and refrigerant with a refrigerant cycle of an air-conditioner. A refrigerant passage connecting to an outlet of the condenser (38) branches at a refrigeration cycle branch point (45) to connect to the refrigerant pump (32) and an evaporator (55). In the case of operating the Rankine cycle, without a request to operate the air-conditioner, the compressor (52) in the refrigeration cycle is driven.
