Patent number: 10224137Abstract: There is provided an electromagnet control apparatus that continuously attracts crushed pieces of metals with the core of a magnetized electromagnet without immediately releasing the attracted pieces in a composite operation of a construction machine. The electromagnet control apparatus includes a control unit that controls a demagnetized state, a magnetized state, or a counter-magnetized state of an electromagnet. Until the end of a first threshold time tth1 from a transition to the demagnetized state from the magnetized state, the control unit ignores a turn-on voltage for turning on first transistors (a first transistor, a fourth transistor) and turns on the first transistors after a lapse of a second threshold time that is shorter than the first threshold time. The demagnetized state and the magnetized state are repeated until the end of the first threshold time tth1 from the transition to the demagnetized state.Type: GrantFiled: November 4, 2016Date of Patent: March 5, 2019Assignees: DYDEN CORPORATION, TAGUCHI INDUSTRIAL CO., LTD.Inventors: Hidenobu Shiki, Yuta Yasumatsu, Yuichi Taguchi

Patent number: 8950714Abstract: In an elongated structure for a movable section, a plurality of operational linear elements such as conductive wires are arranged in parallel in a belt-like sheath member, and an outer region of the sheath member, which is defined by a bend of the sheath member, has a larger rigidity than that of an inner region of the sheath member, which is defined by the bend of the sheath member. When the sheath member 2 have the regions exhibiting the different rigidities, and when an external force is exerted on the elongated structure 1 for the movable section, it is apt to bend toward the side of the sheath member having the small rigidity, and the bent portion is maintained at a given curvature which is determined by the entire rigidity of the sheath member 2. Therefore, the elongated structure 1 for the movable section cannot easily meander while the movable end thereof is moved.Type: GrantFiled: February 3, 2010Date of Patent: February 10, 2015Assignee: Dyden CorporationInventors: Daisuke Ikeda, Yasuaki Kawanami, Kouji Terasaki
