1) When the air channel is blocked, the damping element can flow the air into fan-motor element to reduce the load of motor.

2) Features are: reasonable overall arrangement for air channel, and no reversed-flow region.

3) The instrument's specially designed air channel, it's rounded labium, and it's inner organ(keyhole) makes possible a transparent singing tone.

4) However, the problems and deficiencies are more common with the widely used diaphragm air channel relays exposed in use, low life,[http:///air channel.html] poor reliability and random failure of the contact erosion.

5) This paper proposes the design plan of automatic loading chest machine and introduces in detail the design of control system about the circuit, air channel and software, etc.

6) And then, welding machine total design, the PLC based control system and air channel system, human-machine interface based on configuration software are presented in detail.

7) This paper elucidates the factors and mechanism which result in vibration of the cold air channel system in detail.

8) The flowmeter is different from the prior online pressure floater flowmeter in serial connection with the bottom end of an air channel.

9) Thus, the utility model realizes the performance of adjusting air channels and ensures that the air channel system is in the state of the optimal operation.

10) A motor shaft gap used for a sealing plate for a seal air channel is left between the belt pulley and the end cover of the motor shell.

11) Heater, cooler and temperature sensor are installed in the air channel.

12) Heater, cooler and temperature sensors are installed in the air channel.

13) Valves can be operated by adjusting the air pressure in a chamber below the air channel .

14) This paper discusses the sorts and origins of noises in laser systems in complicated environments, taking as an example laser applications in the air channel.

15) Presently, there are differently extent vibration at the cold air channel system and flue of some boilers these worked many years.

16) Boiler is one of key equipments in power plant; the cold air channel system will directly affect the work of boiler.
