Patent number: 9461447Abstract: A maintenance tool for an insulator of a direct current transmission line comprises clamping devices and a tensioning device. The clamping devices are mounted at the two sides of the insulator through clamping, and the tensioning device is connected between the clamping devices. The clamping devices comprise a closed clamp (1), a single serial clamping device (2) and a wire end clamping device (30). The clamping device has advantages such as strong overall strength and bearing capacity, small size, light weight, and reliable working, and can be applied to replacement of various insulators on the direct current transmission line, reliably ensuring safe commissioning and regular maintenance of transmission lines.Type: GrantFiled: November 29, 2011Date of Patent: October 4, 2016Assignees: State Grid Corporation of China, Hebei Electric Power Maintenance CompanyInventors: Shufeng Kang, Mingxu Zhang, Fengxiang Shi, Xuebin Wang, Juxuan Jiao, Zhi Gao, Zhongsheng Li, Sanping Geng, Yongjie Su, Jian Li, Jun Wang, Boyan Yao, Ming Chen, Qifeng Song

Patent number: 9257945Abstract: Disclosed is a technique for reducing noise superimposed on an output signal while keeping loop gain constant without increasing the circuit scale and without changing the transfer function of the amplifier apparatus (frequency characteristics of gain and phase). According to the technique, there are included a power-supply voltage control unit 7 for detecting the amplitude level S9 of an input audio signal S1 and outputting power with a voltage value indicated by target set voltage value information Vs corresponding to this amplitude level S9, and a PWM modulation unit 2 including a PWM converter 23 for converting the pulse width of the input audio signal S1 and a correction unit for correcting the signal modulated by the PWM converter 23. The PWM modulation unit 2 corrects the pulse width of a PWM signal S5 modulated by the PWM converter 23 so that the correction unit will cancel out a change in amplification gain of a power amplification unit 4 according to the target set voltage value information Vs.Type: GrantFiled: April 20, 2015Date of Patent: February 9, 2016Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Mingxue Zhang, Seigo Ozaki, Tsuyoshi Haga
