Patent EP-4113958-A1 (EP)
Title: Mobile terminal
Inventor: YUAN ZHI
IPC: H04M1/02
Filed: 2021-01-15
Abstract: This application provides a mobile terminal. The mobile terminal includes a rotating member, a flexible screen, a bending support part, and a temperature equalization plate. The flexible screen includes two unfolded regions and a bent region located between the two unfolded regions, and the bent region is disposed opposite to the rotating member. The bending support part is located between the flexible screen and the rotating member, to support the bent region of the flexible screen. The temperature equalization plate includes temperature equalization parts opposite to the two unfolded regions in a one-to-one correspondence and a flexible connection part that connects the two temperature equalization parts. The flexible connection part is located on a side that is of the bending support part and that is away from the flexible screen, to balance temperatures in the two unfolded regions. The flexible connection part of the temperature equalization plate is distributed on the side that is of the bending support part and that is away from the flexible screen. Therefore, even if the temperature equalization plate is slack after being used for a long time, the temperature equalization plate cannot squeeze the flexible screen after being slack and arched, because the flexible connection part of the temperature equalization plate is blocked by the bending support part and cannot be in contact with the bent region of the flexible screen. Therefore, user experience is improved.

Abstract: Methods for producing a hollow spheres, optionally with a vacuum inside, are disclosed. An example method includes providing a seed with a core and a coating. The seed is heated to a temperature sufficient to transform the coating into a continuous shell having an interior and an exterior. The shell isolates the core from the exterior of the shell. The temperature is also sufficient to cause a reaction with the materials of the core, and the reaction converts the core to a gas within said shell. Controlling the rate of heating and the pressure surrounding the shell allows the shell to expand responsive to gas pressure within the shell. Cooling the shell causes the gases within the shell to revert to a solid form, thereby creating a vacuum within the shell. Products incorporating the hollow spheres are also disclosed.
