摘要： A fluid control solenoid valve includes a fluid passage having a valve seat therein. The solenoid valve further includes a bellows having a valve element and a retractable bellows portion continuous with the valve element. The valve element opens the fluid passage when lifted from the valve seat, and closes the fluid passage when seated onto the valve seat. A first spring urges the valve element in a valve lifting direction away from the valve seat, while a second spring urges the valve element in a valve seating direction toward the valve seat. An electromagnetic actuator is further provided for moving the valve element in the valve lifting direction, when energized. The first spring is interposed between an adjusting screw and the valve element. The adjusting screw is arranged to be extended at a high temperature so as to increase a biasing force of the first spring urging the valve element in the valve lifting direction. This prevents a sealing load, which is applied to the valve element to cause it to be seated onto the valve seat, from increasing. Increase in sealing load would be otherwise caused due to thermal expansion of the bellows portion at the high temperature.

摘要： A flow control valve having a seating surface formed on a valve element to contact a valve seat when the valve is closed has a shape of a part of a hypothetical spherical surface having a spherical center at a center of a supporting member. Therefore, the distance from the center of the supporting member to the seating surface is kept constant, and the valve element can be seated at a periphery of the valve seat without a gap, even if the shaft is inclined. Thus, the valve leakage is reduced. The supporting member supports a shaft connected to the valve element movable in an axial direction of the shaft. The center of the supporting member is aligned with a center of the valve seat. Movement of the supporting member in a radial direction of the supporting member is prohibited. Therefore, the center of the supporting member is not displaced from the center of the valve seat in the radial direction. Accordingly, the displacement of the shaft in the radial direction can be prevented. Therefore, the valve element is certainly seated on the valve seat, and the valve leakage is prevented.

摘要： A network type exposure unit connected via a communication network to other exposure units or to an information processor determines whether or not exposure work information of the instructed kind of exposure work is in the storage thereof. When the instructed exposure work information is determined to be non-existent, the unit inquires of the other exposure units or a host equipment whether or not there is therein the exposure work information, and decides executability of the exposure work requested to be started from the result thereof. The exposure work information can be transferred between arbitrary units, thereby alleviating complexity of maintenance and management of the exposure work information.
