Patent number: 9470672Abstract: Disclosed is a method for testing the self-drying effect of a cement-based material, capable of testing the change in humidity of the cement-based material after the final setting until the Id stage of adding water, so as to reflect the water consumption therein and the self-drying course. In the time period after the final setting of the cement-based material until the 1 d stage of adding water and forming, the dew-point temperature inside the cement-based material is tested, and then the relative humidity inside the cement-based material is calculated using a formula. The present invention can test the change in humidity of the cement-based material after the final setting until the Id stage of adding water, so as to reflect the internal water consumption therein and the self-drying course.Type: GrantFiled: December 30, 2011Date of Patent: October 18, 2016Assignee: JIANGSU SOBUTE NEW MATERIALS CO., LTD.Inventors: Jiaping Liu, Qian Tian, Ting Yao, Yujiang Wang, Yujiang Wang, Hang Zhang, Jianye Zhang

Patent number: 8933745Abstract: A transconductance-enhancing passive frequency mixer comprises a transconductance amplification stage, a frequency mixing stage, and an output transresistance amplifier. The transconductance amplification stage has a pre-amplification transconductance-enhancing structure, so that the transconductance is greatly enhanced, thereby obtaining the same transconductance value at a lower bias current. A radio-frequency current is modulated by the frequency mixing stage to generate an output mid-frequency current signal. The mid-frequency current signal passes through the transresistance amplifier, to form voltage output, and finally obtain a mid-frequency voltage signal. The transresistance amplifier has a transconductance-enhancing structure, thereby further reducing input impedance, and improving current utilization efficiency and port isolation. The frequency mixer has the characteristics of low power consumption, high conversion gain, good port isolation, and the like.Type: GrantFiled: May 29, 2012Date of Patent: January 13, 2015Assignee: Southeast UniversityInventors: Jianhui Wu, Xiao Shi, Chao Chen, Zhilin Liu, Qiang Zhao, Junfeng Wen, Xudong Wang, Chunfeng Bai, Qian Tian

Heterodyne interferometric optical fiber displacement sensor for measuring displacement of an object
Patent number: 5402230Abstract: A heterodyne interferometric optical fiber displacement sensor using a laser diode. The frequency and the intensity of the laser diode beam are periodically modulated by an injection current. The laser diode beam is routed to a rod lens via a first optical fiber, an optical fiber coupler, and a second optical fiber. The interference light resulting from the interference between the light reflected from the exit surface of the rod lens and the light reflected from an object surface is routed to a third optical fiber via the optical fiber coupler, which is then detected by a photodiode attached to the end of the third optical fiber. From the output of the photodiode, a given frequency component is extracted using a bandpass-filter. The extracted signal is converted into a pulse signal. The frequency change of the pulse signal (equivalent to a doppler frequency shift caused by the movement of the object surface) is accumulated using an electronic circuit.Type: GrantFiled: December 11, 1992Date of Patent: March 28, 1995Assignees: Tsinghua University, Akira Shimokohbe, Tokyo Seimitsu Co., Ltd.Inventors: Qian Tian, Enyao Zhang, Donglei Tang, Akira Shimokohbe, Masahiro Akahane, Kenji Sakai
