A sealed receptacle includes a case, a cylindrical member, and a closure plate. The sealed receptacle is configured to house a fixed contact, a movable contact, and an arc protection member. The arc protection member includes a peripheral wall, and a bottom. The peripheral wall is configured to conceal a junction between the case and the cylindrical member from the fixed contact and the movable contact. The bottom is interposed between the movable contact and the closure plate. The sealed receptacle houses a contact pressure provision member configured to bias the movable contact to come into contact with the fixed contact. The contact pressure provision member is interposed between the movable contact and the bottom so as to come into resilient contact with both the movable contact and the bottom irrespective of a position of the movable contact.

Provided is a contact device in which all of three movable contacts can be securely brought into contact with fixed contacts. The contact device includes a fixed terminal 37 that has a fixed contact 35, a movable terminal 28 that moves toward and away from the fixed terminal 37 and has three movable contacts 31a, 31b, and 31c that are brought into contact with the fixed contact 35, and a pressing spring 33 that presses the movable terminal 28 and brings the movable contacts 31a, 31b, and 31c into contact with the fixed contacts 35 at a predetermined pressing force. The point of application of the pressing spring 33 is located in a triangle formed by internal tangents of the three movable contacts.

A sealed contact device includes an electromagnet block 2 including a coil bobbin 21, a movable iron core 25, a yoke 26, and a return spring 27; a contact block 3 including a sealing container 31, fixed contact points 32, a movable contact member 35 arranged within the sealing container 31 and composed of a rectangular body portion 35a, first and second protrusions 35b, 35c formed in longitudinal sides of the body portion 35a and movable contact points 34, and a shaft 37; and a case 4. The first and second protrusions 35b, 35c of the movable contact member 35 are formed in non-point symmetry with respect to a connection portion of the movable contact member 35 and the shaft 37 so that, when the movable contact member 35 is rotated, only one of the first and second protrusions 35b, 35c makes contact with the sealing container 31.

A flue gas desulfurization process capable of producing a high purity gypsum and also making equipment employed as minimum as possible is provided, which process comprises the steps of cooling and dedusting flue gas containing SO.sub.x ; contacting the cooled gas with a slurry containing limestone to remove SO.sub.x by absorption and also form CaSO.sub.3 ; controlling the pH of the resulting slurry and then blowing air therein to form gypsum; and separating gypsum from the resulting slurry. As a modification of the above process, the slurry of the above second absorption step is further fed to the above first cooling step where unreacted limestone and SO.sub.x are reacted to form CaSO.sub.3.
