Publication number: 20240139847Abstract: A brazing joint, a brazing method, and a device for promoting solder rheology and gas overflow are provided. The brazing joint includes a first base metal, a second base metal, and a brazing seam located therebetween. The brazing seam is formed by filling a solder in a gap formed by welding surfaces of the first and the second base metal and melting it to connect the first and the second base metal. The brazing seam is a concave-shaped brazing seam. The gap defines a first distance and a second distance, the first distance is located at an edge of the gap, the second distance is located at the edge or an inside of the gap, the first distance is greater than the second distance, and a curved surface is formed between the location of the first distance and the location of the second distance for transition.Type: ApplicationFiled: December 9, 2022Publication date: May 2, 2024Applicants: CHINA ACADEMY OF MACHINERY NINGBO ACADEMY OF INTELLIGENT MACHINE TOOL CO., LTD., ZHENGZHOU RESEARCH INSTITUTE OF MECHANICAL ENGINEERING CO., LTD.Inventors: Weimin LONG, Xiaoguo SONG, Sujuan ZHONG, Lianhui JIA, Limei JIN, Yucan FU, Yongqiang WEI, Yuchang WANG, Guoqin HUANG, Lei ZHANG, Long FU

Publication number: 20240130068Abstract: Technologies for a flexible three-dimensional power plane in a chassis are disclosed. In one embodiment, a flexible ribbon cable is laid along a circuit board tray. The flexible ribbon cable is secured to the tray using power bosses. The power bosses connect to one or more conductors on the ribbon cable. When the circuit board is mounted on the circuit board tray, the power bosses extend through holes in the circuit board and mate with power clips on the surface of the circuit board tray. The ribbon cable, power bosses, and power clips can distribute power to various locations on the circuit board, without requiring large traces that take up space on the circuit board.Type: ApplicationFiled: December 28, 2023Publication date: April 18, 2024Applicant: Intel CorporationInventors: Nan Wang, Zhichao Z.

Patent number: 11459256Abstract: The present invention discloses a tower-shape integrated ecological purification device for domestic sewage in a small town. The device includes a water storage and filter pond, a medium reverse osmosis pond, an amphibious biological reaction system, and an aquatic biological reaction system. The amphibious biological reaction system and the aquatic biological reaction system are alternately connected from the top down. The amphibious biological reaction system and the aquatic biological reaction system form an alternating dry and wet, oxidation-reduction compound environment. Plant absorption, biological substrate transformation, aeration, and strengthening medium adsorption are combined to form a multi-stage plant-microbe-animal integrated ecological purification treatment process/device. The present invention achieves the efficient purification and acceptable discharge of domestic sewage in small towns.Type: GrantFiled: September 28, 2020Date of Patent: October 4, 2022Assignee: Institute of Mountain Hazards and Environment, Chinese Academy of SciencesInventors: Bo Zhu, Zhixin Dong, Tao Wang, Xiaoguo Wang
