  • Publication number: 20240106322
    Abstract: In a power conversion system, a control circuit has, as its operation modes: a first control mode in which control circuit controls a DC-DC converter at a first drive frequency; a second control mode in which control circuit controls DC-DC converter at a second drive frequency higher than first drive frequency; and a third control mode in which control circuit controls DC-DC converter at a third drive frequency higher than first drive frequency. Control circuit is configured to change operation mode from first control mode into second control mode when detector circuit detects a predetermined change in output voltage while control circuit is operating in first control mode. Control circuit controls DC-DC converter in third control mode in a process of changing, in response to detection of predetermined change, operation mode from first control mode into second control mode before starting to control DC-DC converter in second control mode.

  • Publication number: 20170191269
    Abstract: The invention relates to a fastening device for fastening at least one mounting element to a threaded bolt, including a nut having a threaded bore and a clamping element that interacts with the nut and has an opening. The nut has a conical supporting region on the outside. In the mounted state, the nut engages at least partly in the opening of the clamping element and rests on a complimentary inner cone which the clamping element has. The nut has at least one slot which interrupts the nut wall over a sub region of the axial extent of the latter. The at least one slot opens at the axial end of the nut which is located closer to the larger diameter than to the smaller diameter of the conical supporting region is designated as the top end. The clamping element can be screwed into a mounting element.

  • Patent number: 9387605
    Abstract: A method for manufacturing a reinforcing member (2) consisting of fiber-reinforced plastic for mineral construction materials, in particular for concrete. In the method, curing the composite fiber rod (1) takes place in at least three stages (7, 16, 25) sequencing one after another, wherein after the first stage of curing (7) at least one radiation-reflecting and/or thermally-insulating covering agent (15) is applied onto the pre-cured composite fiber rod (1), wherein a second stage of curing (16) of the composite fiber rod (1), together with the covering agent(s) (15) applied is executed, in which the composite fiber rod (1) is further cured in the regions (14) not covered by the covering agents (15) by the supply of heat and/or radiation, and wherein the deformation (23) of the composite fiber rod (1) is executed between the second stage of curing (16) and the final stage of curing (25).

  • Patent number: 8172484
    Abstract: The invention relates to a fiber-reinforced plastic drilling anchor comprising an axial bore that runs along the entire length thereof, fibers which extend in the longitudinal direction thereof, and fibers that extend at an angle to the longitudinal direction thereof. A first layer of fibers that extend at an angle to the longitudinal direction of the drilling anchor is surrounded by a second layer of fibers extending in the longitudinal direction of the drilling anchor, and the second layer of fibers is surrounded by a third layer of fibers extending at an angle to the longitudinal direction of the drilling anchor. The inventive drilling anchor further comprises a thread which extends along the entire length thereof and is molded into at least one outer fiber layer of the drilling anchor. The invention also relates to a method for producing such a drilling anchor.

  • Publication number: 20100296891
    Abstract: The invention relates to an anchor nut (1) that is made of fiber-reinforced plastic and comprises an internal thread (6) to be screwed onto a thread of an anchor (16). Said anchor nut (1) has external contours or shapes, by means of which the anchor nut (1) can be screwed onto an anchor winding with the help of a positively acting tool. One end of the anchor nut (1) is fitted with a first torque limiting means (7) which prevents a partially screwed-in anchor (16) from being further screwed in at a torque lying below a first torque limit, while the other end thereof is fitted with a second torque limiting means (8) that prevents torque from being further transmitted to the anchor nut (1) via the positively acting contours or shapes when a second torque limit has been reached or is exceeded. The first torque limiting means is formed by a pin (7) which penetrates the internal thread (6) perpendicular to the longitudinal axis of the anchor nut (1).
