The invention provides a lane-keeping control method and a lane-keeping system. After the lane-keeping system receives opening signals of a lane-keeping switch, a lane identifying device collects road information, a car body information collecting device collects car body information, and a lane-keeping control device controls an initiative steering system to adjust the traveling direction of a car according to the road information and the car body information. In the process of adjusting the traveling direction of the car, if the lane-keeping control device receives operation switching signals, the lane-keeping system is turned off, and a driver controls traveling of the car; if the lane-keeping control device receives torque signals of applying torque on a steering wheel, the lane-keeping control device controls the initiate steering system to offset the torque. The lane-keeping system conducts analysis treatment on the operation of the driver in the process of adjusting the traveling direction of the car and can conduct corresponding treatment on drivers' different operation motions on the car.

The gate includes a latching part and a locking ring fitted coaxially around the gate. An end head of the gate partially surrounds the securing part in the closed position, and includes a shoulder acting as end-of-travel stop for the ring in the locked position.

This invention is to provide a substrate treating device which can satisfactorily attract a substrate to its substrate placing part and, at the same time, from which the substrate attracted to the substrate placing section can be removed satisfactorily even when the size of the substrate is increased. A plurality of adsorption grooves 75 formed on the holding surface of the substrate treating device in a grid-like state are connected to each other at grid points 76. A part of the grid points 76 communicates with suction holes 72. The suction holes 72 are connected to a vacuum pump in communicating states through piping. End-section lifter pins 71a and central-part lifter pins 71b are independently provided in vertically movable states. Consequently, (1) the substrate treating device can attract the whole bottom surface of an angular substrate W even when the device does not have many attraction holes in the holding surface and (2) can attract the angular substrate W to the holding surface from the vicinity of the central part of the substrate W to the end section of the substrate W.

A controller based on VAV air conditioner fresh air optimizing allocation belongs to the building surroundings equipment as well as control technique field. In the invention, the input module captures required data to transmit to the storage module, the storage module stores the desired data, the fresh air calculation and control module calculates the total fresh air amount of the system and fresh air amount of each area and their ratio, the maximum fresh air requirement ratio is found out to be the fresh air ratio setting value for system air blow. The fresh air valve control module takes the total fresh air amount as the setting value, and the results are transmitted to the fan valve executor according to PID control. A double cold control module calculates the air blow setting enthalpy value of each area terminal, which is transmitted to a water flow regulate module controlled by the enthalpy difference, and the module transfers the valve position information to the water valve executor according to PID control based on the air blow setting enthalpy value and sampling value passing through the termini serpentinepipe.
