The engagement structure includes an elastic component and an engagement block used for fixing the elastic component. The engagement block is fixed to the inner container. The elastic component includes a buckle and an elastic element. The buckle is provided with a buckle hole. One part of the elastic element is disposed in the buckle hole, and another part of the elastic element is in elastic contact with the inner container.

Abstract: Disclosed are a device for expansion and contraction through rotation of a rotary shaft and a VR headset. The device includes a first connecting housing, a second connecting housing, a third connecting housing, a connecting member and a positioning member. One end of the second connecting housing is rotatably connected to one end of the first connecting housing, and the third connecting housing is provided with a second inclined surface configured to fit a first inclined surface of the second connecting housing. The connecting member is configured to fix the first connecting housing, the second connecting housing, and the third connecting housing. The positioning member is configured to control the second connecting housing and the third connecting housing to avoid deviation when the second connecting housing and the third connecting housing rotate relative to each other. The present application effectively improves the operating comfort for the user.

Abstract: The present disclosure discloses a viewing angle compensation method and apparatus for a display panel, and the display panel, and relates to the technical field of liquid crystal displaying. The purpose of increasing a visual angle of an MVA liquid crystal panel can be achieved, and for a whitening phenomenon of a screen watched at a side viewing angle, a better improving effect can be given.

Abstract: A modified socket for a plug having two pins to plug therein includes a casing, a rotatable cap, two pairs of electrical clips and a resilient means. The rotatable cap is rotatable between an inserting position and a power-on position. Each pair of electrical clips is disposed in the casing and has a fixed jaw and a movable jaw. The movable jaw is movable between a home position and an accumulating position. The resilient means is adapted for accumulating resilient force when the movable jaws are moved toward the accumulating positions and for releasing the resilient force to move the movable jaws to the home positions. During the rotation of the rotatable cap from the inserting position to the power-on position, the resilient means will accumulate the resilient force and then release it. The movable jaws will then contact and electrically connect to the pins.

Abstract: The voice advertisement delivery system includes a user terminal, an advertiser terminal, and a voice advertisement delivery server. The voice advertisement delivery server receives designation of a preferred location to which voice advertisement is delivered from the advertiser terminal and acquires user location information indicating the location of a user and user direction information indicating the direction of the user. The user location information is transmitted to the voice advertisement delivery server. The advertisement location information and voice advertisement data are delivered to the user terminal when the user location information approaches the designated advertisement location information and satisfies a predetermined condition. The user terminal operates spatial sound and reproduces the voice advertisement.

Abstract: The present invention relates to a process of manufacturing skiing equipment using a high-entropy alloy, especially manufacturing for a bottom member of a ski, a blade of an ice skate shoe or the bottom member of a skiing vehicle. The high-entropy alloy is used to prepare skiing equipment, so that the skiing equipment has a small friction coefficient, obtains good speed, and can be driven with less energy, which realizes energy-saving effect.

Abstract: A recycled-carbon-fiber tow composition comprising a recycled carbon fiber tow taken from a carbon-fiber-reinforced thermosetting resin molded body; and a surface modifier having a chemical functional group (hereinafter, referred to as second chemical functional group) that has chemical affinity with a chemical functional group (hereinafter, referred to as first chemical functional group) existing on a surface of the carbon fiber, wherein the recycled carbon fiber tow is formed such that carbon fibers are bundled into a tow with amorphous carbon that substantially contains no resin residue, the recycled-carbon-fiber tow composition contains 0.1 to 1 weight % of the surface modifier when an entirety of the recycled-carbon-fiber tow composition is 100 weight %, and n amount of residual carbon content measured when the recycled-carbon-fiber tow composition has been heated in a condition of 600° C.×60 minutes is 1 to 5 weight %.
