In a clock-synchronized serial communication device, a counter counts pulses in a communication clock signal. When the count reaches 8, the counter sets a start signal. With this start signal, a pulse generator outputs the first to fourth signals successively. Received data stored in a receiving shift register is transferred to a received-data processing circuit synchronously with the first signal. The received data is further transferred to a timer-setting value register as a timer-setting value synchronously with the second signal. A timer present value is output from a timer present value register synchronously with the third signal. The timer present value is further written into a transmitting shift register as transmission data synchronously with the fourth signal.

A method for controlling a constant-pressure fluid enables an inverter with a build-in controller to control rotation speed of a pump to achieve constant-pressure control thereof. In the control method, a pressure feedback value of output flow of the pump is measured and is compared with a pressure reference value to produce an error pressure value. Afterward, an operation condition of the pump, such as an abnormal handling condition, a deceleration standby handling condition, or an acceleration condition, is determined according to the pressure error value to shut down or re-start up the pump after a delay time. Hence, the control method can avoid frequently starting up or shutting down the inverter. Therefore, the power consumption and the operation cost are reduced. The use life of the pump prolongs and constant-pressure control for the pump can be implemented.

A stage control apparatus for controlling a stage on which a substrate can be placed and moved generates a target value relating to a vertical direction of the stage based upon substrate surface position information that corresponds to unevenness of the surface of the substrate and generates a drive command signal of the stage based upon a deviation signal between the target value generated and a measured position of the stage. A target frequency is decided upon a spatial frequency possessed by the unevenness of the substrate surface. In order to generate the drive command signal, use is made of a signal obtained by amplifying a component of the target frequency of the deviation signal.
