Abstract: A substrate held by a holder is housed in a treatment chamber. An electrode set is disposed so as to face a surface of the substrate. Each electrode set consists of a first electrode section and a second electrode section. Each of the first and second electrode sections consists of high-frequency electrodes and/or ground electrodes. Process gas emitted through introduction ports is fed between the electrodes to generate plasma. The generated plasma is used to remove contaminated substances adhered to the surface of the substrate.

Abstract: A vehicle safety system includes an obstacle detecting device for detecting an obstacle around a vehicle; a vehicle state detecting device for detecting states of a speed, acceleration, turning sideways, sudden braking, sudden revolving, sideslipping and the like of the vehicle; a dangerous degree determining device for determining a dangerous level of the obstacle with respect to the vehicle or dangerous level of the vehicle itself by receiving information from the obstacle detecting device and/or the vehicle state detecting device; a seat belt device for changing a shape, including an area of a belt, of a touching portion where the belt touches an occupant according to dangerous level information from the dangerous degree determining device; and an occupant identifying device for storing physical characteristics of the occupant sitting on a seat corresponding to the seat belt device.
