Abstract: In case of using multi-contacts or flat braided wires for constituting a current carrying structure of a movable part in a s vacuum relay, problems tend to appear, which are enlargement of a control mechanism, complication, increased operation force and the like. The vacuum relay 1 includes an insulating cylinder 2, a first relay connecting portion 4 that is connected to one open end of the insulating cylinder 2 and has on its inner surface a first to contact 3, a second relay connecting portion 5 that is arranged in the insulating cylinder 2 to face the first relay connecting portion 4, a movable member 7 that is movably arranged between the first and second relay connecting portions 4 and 5 and has a second contact that is brought into contact with the first contact when the movable member is moved toward the first relay connecting portion, and a control mechanism 8 that moves the movable member 7 in both directions to establish and break the contact between the two contacts. Between the movable member 7 and the second relay connecting portion 5, there is provided a bellows 11 through which the movable member 7 and the second relay connecting portion 5 are electrically connected.

Abstract: It is a CNT device (1) (carbon-metal structure) equipped with a carbon nanotube layer (2) (CNT layer 2; same hereafter) on a metal pedestal (4). The metal pedestal (4) is brazed to the CNT layer (2) with a brazing material layer (3) interposed therebetween. When manufacturing the CNT device (1), firstly, the CNT layer (2) is formed on a heat-resistant textured substrate (6). Next, the metal pedestal (4) is brazed to the CNT layer (2) that is on the heat-resistant textured substrate (6) with the brazing material layer (3) interposed therebetween. Then, the metal pedestal (4) (and the CNT layer 2) is peeled off the heat-resistant textured substrate (6) to transfer the CNT layer (2) from the heat-resistant textured substrate (6) to the metal pedestal (4).

Abstract: In a vacuum chamber (1), an emitter (3) and a target (7) are opposed to each other. A guard electrode (5) is disposed around an outer circumference of an electron generating portion (31) of the emitter (3). A supporting part (4) supports the emitter (3) movably in an end-to-end direction of the vacuum chamber (1). Reforming treatment is performed on the guard electrode (5) by operating the supporting part (4), moving the emitter (3) to an open end (21) side (non-discharge position) and applying a voltage to repeatedly effect discharge on the guard electrode (5) in a state where field emission from the electron generation portion (31) is suppressed. After the reforming treatment, the supporting part (4) is again operated. The emitter (3) is moved to an open end (22) side (discharge position) and placed in a state where field emission from the electron generation portion (31) is allowed.
