Patent number: 11492766Abstract: The present invention discloses a method of hot recycling repairing by optimizing a proportion of an asphalt mixture on a pavement alignment variation section. According to the method of the present invention, by regulating and optimizing the proportion of a recycled asphalt mixture, internal frictional resistance and cohesion of the recycled asphalt mixture are improved, elastic modulus and shear strength of the recycled asphalt mixture are increased, overall bearing capacity of an asphalt pavement is improved, and diseases such as tracks caused by vehicle loads are effectively resisted. The pavement asphalt mixture is made to adapt to and be enough to bear additional loads increased manifold without generating early defects and road diseases. Therefore, the overall service life of a road is further prolonged.Type: GrantFiled: July 10, 2019Date of Patent: November 8, 2022Assignee: FREETECH THERMAL POWER CO., LTDInventors: Wai Pan Sze, Yifu Zhang, Kai King Chan, Min Chen, Wei Zhu, Quan Niu

Patent number: 9721490Abstract: A dual-screen display and a display method. The dual-screen display comprises: a display unit, a control unit and controllable light-transmitting bodies. Each display unit comprises at least three sub-pixel units. The controllable light-transmitting bodies are distributed on an upper surface and a lower surface of the sub-pixel units. The control unit is used for controlling, according to an instruction of a user, a control signal applied to the controllable light-transmitting bodies, so as to control the transparency of the controllable light-transmitting bodies. The controllable light-transmitting bodies are distributed on the two surfaces of the sub-pixel unit, and a control signal is applied according to an instruction of the user, so that the controllable light-transmitting bodies present corresponding transparency, thereby respectively controlling light of the sub-pixel unit irradiated to the two surfaces.Type: GrantFiled: January 9, 2013Date of Patent: August 1, 2017Assignees: Beijing Lenovo Software Ltd., Lenovo (Beijing) Co., Ltd.Inventors: Guang Yang, Ke Shang, Quan Niu
