Publication number: 20240106322Abstract: 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.Type: ApplicationFiled: January 22, 2022Publication date: March 28, 2024Inventors: Hirokazu NAKAMURA, Kohei TSUKAMOTO, Kenichi ASANUMA, Ryoji MATSUI

Publication number: 20100296891Abstract: 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).Type: ApplicationFiled: June 16, 2008Publication date: November 25, 2010Applicant: FiReP Rebar Technology GmbHInventor: Kenichi Tsukamoto
