Patent number: 11964428Abstract: The present invention provides a bottom plate of a resin tank for three-dimensional printing, which is manufactured through the following steps: substrate surface roughening step: treating the upper surface of a transparent substrate by using a plasma, or disposing a composite film on the upper surface of the transparent substrate to form a non-smooth surface structure having pores; substrate surface modification step: sequentially performing an activation treatment and a fluorination treatment on the upper surface of the transparent substrate; and stabilizer filling step: applying a stabilizer to the upper surface of the transparent substrate to fill the stabilizer penetrates into the pores on the upper surface of the transparent substrate. The low surface energy film reduces the adhesion of the hardened photosensitive material, and the stabilizer maintains the structure of the low surface energy film, so that the resin tank bottom plate has both oleophobic and hydrophobic properties.Type: GrantFiled: March 10, 2022Date of Patent: April 23, 2024Assignee: National Taiwan University of Science and TechnologyInventors: Jeng-Ywan Jeng, Ming-Hua Ho, Ping-Hsun Tsai

Patent number: 11953052Abstract: A fastener is adapted for assembling a first housing to a second housing. The first housing is provided with a protruding portion and a buckling portion, and the second housing has a first surface, a second surface, and a through hole. The fastener includes a first portion, at least one connecting portion, at least two elastic portions, and a second portion. The first portion movably abuts against the first surface and has a first opening. The connecting portion is accommodated in the through hole. One end of the connecting portion is connected to the first portion. The connecting portion is spaced apart from an inner edge of the second housing by a gap. The two elastic portions inclinedly extend into the first opening. The second portion movably abuts against the second surface and is disposed at the another end of the connecting portion.Type: GrantFiled: June 17, 2021Date of Patent: April 9, 2024Assignee: PEGATRON CORPORATIONInventors: Jian-Hua Chen, Po-Tsung Shih, Yu-Wei Lin, Ming-Hua Ho, Chih-Hao Wu

Patent number: 11153982Abstract: A rollable structure includes an outer and an inner sliding rail. The outer sliding rail includes outer sliding blocks and outer shafts. Each of the outer shafts is fixed between any two adjacent outer sliding blocks. The inner sliding rail is movably clamped in the outer sliding rail and includes inner sliding blocks and inner shafts. Each of the inner shafts is fixed between any two adjacent inner sliding blocks. When axes of the outer shafts are aligned with axes of the inner shafts, the outer sliding blocks can rotate with the outer shafts as axes, and the inner sliding blocks can rotate with the inner shafts as axes. After the inner and the outer sliding rail move relative to each other, the axes of the inner and the outer shafts are misaligned, so that the outer and the inner sliding rail are in a plane.Type: GrantFiled: May 8, 2020Date of Patent: October 19, 2021Assignee: PEGATRON CORPORATIONInventors: Ming-Hua Ho, Yu-Wei Lin, Po-Tsung Shih
