An AP allows a CTS generator provided within a control unit to generate a self-destined, e.g., IEEE802.11b standard-based CTS signal containing a duration time corresponding to each standard. Then, the AP notifies to each STA operated based on the 11b standard in a basic service set, that it is being ready for transmission due to the transmission of the CTS signal, thereby to prohibit the operation of the corresponding STA. Further, the AP transmits a beacon based on an IEEE802.11g standard to thereby set a condition based on this standard and is caused to perform transmission/reception to and from the corresponding STA alone over the duration time indicated by the 11b standard. In a reverse case, the AP transmits a CTS signal containing a self-destined duration time under the IEEE802.11g standard to prohibit the operation of the corresponding STA based on the 11g standard. Further, the AP transmits a beacon based on the 11b standard to thereby set a condition based on this standard and is caused to perform transmission/reception to and from the corresponding station alone over the duration time indicated by the 11g standard.

A bellows, of which one end portion is fixed to a movable lever passing through a vessel wall and the other end portion of which is fixed to the vessel wall, has a spring constant at a central portion in an expansion direction which is smaller than that at the end portions in the expansion direction. The bellows damps stress concentration at the end portions and improves the life thereof, without enlarging the size of the bellows. The bellows may be used in a vacuum switch.

A tool holder holding in a fluid supply hole 3d having an inner diameter a tool 1 having the diameter of identical with or smaller than said inner diameter through a collet 2, wherein a fluid can be supplied from the fluid supply hole 3d to a fluid channel 1c of the tool 1, in the fluid supply hole 3d, a seal block 11 as a regulating means which regulates a flowing amount of the fluid to the fluid channel 1c of the tool 1 and the flowing amount of the fluid to the gap between the fluid supply hole and the tool 1 is provided slidably in the longitudinal direction of the fluid supply hole. The seal block 11 adheres close to the end of the tool 1 due to the fluid pressure in the fluid supply hole 3d and the fluid is supplied to the close adhesion portion, thereby the fluid flowing amount to the channel 1c of the tool 1 can be regulated.

A reaction byproduct which is generated when a ferro-dielectric material film is etched is removed without giving adverse effect on the semiconductor element. After the etching of the ferro-dielectric material film, a wetting process may performed using an aqueous solution of phosphoric acid. After the ferro-dielectric material film is etched using the resist as the mask, the wetting process is also performed using the aqueous solution of phosphoric acid before and after the ashing of resist.
