  • Patent number: 10181569
    Abstract: An improved switching material for forming a composite article over a substrate is disclosed. A first volume of nanotubes is combined with a second volume of nanoscopic particles in a predefined ration relative to the first volume of nanotubes to form a mixture. This mixture can then be deposited over a substrate as a relatively thick composite article via a spin coating process. The composite article may possess improved switching properties over that of a nanotube-only switching article. A method for forming substantially uniform nanoscopic particles of carbon, which contains one or more allotropes of carbon, is also disclosed.

A resiliently deformable band (1) extends around the switch unit (40) above a polygonal-section contact zone (2), such that fingertip pressure on the band (1) may locally depress the band (1) towards a flat area (12) of the contact zone (2). Switch contacts (11) are mounted to an inner surface of the band (1) opposite a plated circuit (10) located on each flat area (12) so as to form a plurality of switches. A switch to activate the tool is thus easily accessible to a user's fingertip in any orientation of the handpiece in the user's hand.

The absence of this minimum current in the induced circuit (15) causes the opening of additional releasing device (20). In the latter case, it is possible to obtain this feature by establishing when induced circuit (15) of residual current circuit breaker (200) is flown by a current beyond the maximum threshold.

  • Patent number: 7611784
    Abstract: A switch assembly for selectively enabling current flow through a segment of a fuel cell stack. The switch assembly includes a first plate including a first non-conductive substrate having a first conductive path therethrough and a second plate including a second non-conductive substrate having a second conductive path therethrough. A first switch is disposed between the first plate and the second plate and is in electrical communication with the first conductive path and the second conductive path. The first switch is operable in an open mode to prohibit current flow between the first conductive path and the second conductive path. The first switch is operable in a closed mode to enable current flow between the first conductive path and the second conductive path.

    Abstract: A first wiring layer 16 is disposed on an insulating film 14 on the lower surface of an upper substrate 15, while a second wiring layer 13 three-dimensionally crossing the first wiring layer 16 is provided on the insulating film 12 on a lower substrate 11. A cantilever 17 has one end connected to the first wiring layer 16 and the other end opposed to the second wiring layer 13 with a space therebetween. A thermoplastic sheet 19 is arranged on the upper substrate 15 so as to cover the through-hole 18. The thermoplastic sheet 19 is pressed by a heated pin 20 against the cantilever 17 and deformed so as to maintain the connection between the cantilever 17 and the second wiring layer 13, and therefore close the switch 10.

  • Patent number: 7334319
    Abstract: The aim of the invention is to improve the breaking ability of vacuum interrupter in the medium- and high-voltage range. Said aim is achieved whereby the contact pieces which may be displaced relative to each other are moved with a relatively high speed during a first phase (S1) of the separation process until about ¼ to ½ of the ultimate separation (extinction stroke Eh) and are brought to the given ultimate separation (isolating stroke Eh) during a second phase (S2) with relatively low speed.

  • Patent number: 7012204
    Abstract: A silver contact fixing structure for conductive blades aims at providing a retaining force on a silver contact so that the silver contact is more secure and does not break loose when subject to striking. The silver contact is built in a fastening section formed on a conductive blade. The fastening section has at least two fixing zones connecting to each other and a bucking end adjacent to the fixing zones to increase the retaining force between the silver contact and the conductive blade so that the silver contact does not break loose easily thereby increasing the service life thereof.

  • Publication number: 20040093718
    Abstract: In an actuator of the invention, coils are kept from being displaced along a y-axis direction as projections of coil bobbins are sandwiched between first and second iron cores along the y-axis direction. Also, the coils are kept from being displaced excessively along x- and z-axis directions due to shocks, for instance, as they are fitted in groovelike channels formed in the first and second iron cores. Since two bearings are sandwiched and fixed between third and fourth iron cores along the x-axis direction, the bearings can be easily set on a common axis with high accuracy. It is therefore possible to prevent displacement of the coils during operation of the actuator. Slidable support plates ensure smooth movements of an armature and thereby provide improved reliability even when the distance between the support plates and the first to fourth iron cores is reduced.

  • Patent number: 6362710
    Abstract: For increasing the reliability of contact closure in safety relays, a contact spring (10) is provided with two contact pieces (15, 16) which are disposed at the free end of the contact spring (10), spaced transversely of the longitudinal axis thereof and cooperate with contact pieces (17, 18) disposed on a common fixed contact. The contact spring (10) has a zone (19) in which it is not only flexible but also sufficiently torsional about its longitudinal axis in order to ensure the closure of both contact couples. Disposing the free end of the contact spring (10) carrying the contact pieces (15, 16) at an angle with respect to the fixed contact (12) achieves smooth and low-bounce contact closure and at the same time provides the function of a pre-contact and a main contact.
