Publication number: 20240044512Abstract: The present invention discloses an oven lid of a large-capacity air oven. The key point of the technical solution of the present invention is that the oven lid of the large-capacity air oven includes a casing, a middle casing is arranged inside the casing, and an inner casing is fixedly connected to the bottom of the middle casing; a DC brushless motor is employed, and due to the fact that the size of the DC brushless motor is small, which allows the space between the inner casing and the middle casing to be compressed, thereby expanding the volume of an inner oven body and making the space of the air oven larger; and in addition, a first recess, a second recess and a third recess are provided, so that structures among the middle casing, the inner casing, an exhaust fan and a circulation fan are more compact.Type: ApplicationFiled: June 30, 2023Publication date: February 8, 2024Inventors: Fangsheng DAI, Yiwei XU, Junchao YUAN, Jian WANG

Patent number: 9401346Abstract: An optical bus of an integrated circuit comprises: a polymer waveguide, a micromirror, and an optical coupler. The polymer waveguide is disposed in a via formed through at least one die layer of the integrated circuit comprising an active circuit. The micromirror is disposed adjacent to the via and optically coupled to the polymer waveguide. The optical coupler is connected to the polymer waveguide to couple the active circuit to the optical bus. A stacked integrated circuit is described comprising such an optical bus. A method of fabricating a rear 45° micromirror on a silicon substrate that can be used in the optical bus is also described. Furthermore, alignment/lock mechanisms for use in a stacked integrated circuit comprising first and second silicon substrates are described.Type: GrantFiled: January 9, 2015Date of Patent: July 26, 2016Inventors: Chee Yee Kwok, Aron Michael, Yiwei Xu
