    • A tire air pressure detecting device has a tire air pressure detecting device on a wheel. A main transmitting device is provided at the wheel for transmitting an air pressure signal SP to a vehicle body. A main receiving device is provided at the vehicle body for receiving the air pressure signal SP. A main switch turn-on detecting device is provided on the vehicle body for detecting the turn-on of a main switch. A second control device is provided on the vehicle body for receiving the air pressure signal SP and a main switch ON signal Son. An auxiliary transmitting device on the vehicle body transmits a transmission instruction signal SR to the wheel when the second control means receives the main switch ON signal Son. An auxiliary receiving device on the wheel receives the transmission instruction signal SR. A first control device is provided for reading a new air pressure signal SP. When the main switch is turned on, the state of the tire air pressure can immediately be recognized. The main transmitting means is not required to transmit the air pressure signal at all times or increase the frequency with which to transmit the air pressure signal. Thus, the consumption of the battery at the wheel can be reduced.

    • A gas recirculation flow control method and apparatus for use in an evacuation system having a vacuum chamber into which a gas is introduced, a first vacuum pump for exhausting the gas from the vacuum chamber and reducing the pressure in the vacuum chamber to a desired pressure, a second vacuum pump for performing evacuation to lower the back pressure of the first vacuum pump below an allowable back pressure, and a gas recirculation line for returning a part of gas exhausted from the first vacuum pump to the vacuum chamber. The recirculation flow rate Q2 of the gas returning to the vacuum chamber through the gas recirculation line is controlled by adjusting the differential pressure Pd−Pc in the gas recirculation line by varying the effective pumping speed of the second vacuum pump using the following relationship: Q2=C×(Pd−Pc) where: Q2 denotes the recirculation flow rate of the gas returning to the vacuum chamber through the gas recirculation line; Pc denotes the pressure in the vacuum chamber; Pd denotes the pressure in the upstream side of the gas recirculation line; and C denotes the conductance of the gas recirculation line.
