Title: Oscillation circuit
Inventor: MORI YUKI
IPC: H03G3/30
Filed: 2000-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a simple circuit configuration in which stable oscillation signals with an appropriate amplitude level can be produced. SOLUTION: The polarity of the voltage between a first input terminal 8 and a second input terminal 10 in a first differential amplifier circuit 4 is reversed every half period of the transmission signal Vout. Therefore, in a transistor Q1 and a transistor Q2, the base and the emitter are alternately reverse- biased, and the voltages in the bases of the transistors Q1, Q2 appear alternately in the emitters of the transistors Q1, Q2, so the lip component of the emitter voltage Va becomes similar to the fully-rectified waveform of the transmission signal Vout. The current control circuit 6 generates the control voltage 20 by smoothing the emitter voltage Va and applies it to the base of the transistor Q4. As a result, the larger amplitude level of the transmission signal Vout reduces the idling current I0 as the amplification degree decreases.  Conversely, the smaller amplitude level of the transmission signal Vout raises the idling current I0 as the amplification degree increases.

Filed: 2000-02-07
Abstract: PROBLEM TO BE SOLVED: To eliminate some disadvantages that a structure of the prior art water tube boiler becomes complicated and its manufacturing cost becomes expensive due to a drum structure of its main body. SOLUTION: This water tube boiler has a simple structure and its manufacturing cost becomes less-expensive by employing a rectangular header with its sectional surface being turned by 45 deg. in place of upper and lower drums.

Both ends of the header are of a blind-plate structure to enable an inspection of the water contact surface to be carried out and no trouble is generated at its maintenance and inspection work. In addition, both economizer and an air pre-heater are arranged at an auxiliary heat transfer surface to attain a sufficient improvement of thermal efficiency.
