Patent number: 11747862Abstract: A portable information device includes: a chassis; a decorative plate fixed to a part of an outer face of the chassis with stretch releasable double-sided adhesive tape; and a cover member that covers the outer face and the decorative plate. The double-sided adhesive tape has: an adhesive portion including adhesive layers on first and second faces of a substrate for adhesively fixing between the decorative plate and the outer face; and a tab including release paper partially covering the adhesive layers to let a user hold the tab for stretch release of the adhesive portion from between the decorative plate and the outer face. The double-sided adhesive tape has a first groove and a second groove on the first face and the second face, respectively, that are positioned not to overlap in a thickness direction of the substrate.Type: GrantFiled: February 1, 2021Date of Patent: September 5, 2023Assignee: LENOVO (SINGAPORE) PTE. LTD.Inventors: Shigehiro Horiuchi, Takehito Yamauchi, Tetsuya Sano, Yuta Tsuganezawa

Patent number: 10444793Abstract: There is provided an electric device having such a structure that members are moved by a driving force of an electric motor. The electric device comprises: an electric motor; a driving member which receives a driving force from the electric motor to advance and retreat; a moving member pressed by the driving member to move; a stopper which restricts a moving range of the moving member; and a cushioning mechanism located on a pressing part of the driving member against the moving member or a pressure-receiving part of the moving member pressed by the pressing part configured to transmit a pressing force of the driving member to move the moving member before the movement of the moving member is restricted by the stopper, and to absorb the pressing force of the driving member after the movement of the moving member is restricted by the stopper.Type: GrantFiled: August 23, 2016Date of Patent: October 15, 2019Assignee: LENOVO (SINGAPORE) PTE. LTD.Inventors: Yoshiyuki Shibayama, Yuta Tsuganezawa, Eiji Shinohara
