Abstract: The present invention provides a solid beverage containing barley leaves, comprising the following components: 15-60 wt. % of a barley leaf micro-powder, 10-50 wt. % of xylitol granules, 5-20 wt. % of a matcha powder, 1-10 wt. % of inulin, 0.5-4.0 wt. % of a konjac powder, 0.2-3.0 wt. % of silicon dioxide, and 0.1-3.0 wt. % of sucralose. The present invention also relates to a method for preparing the solid beverage, comprising the following steps: mixing a barley leaf micro-powder, inulin, a konjac powder and matcha powder, and then performing wet granulation on same to obtain granulated powders; passing the granulated powders through a 20-mesh sieve after drying same to obtain whole granules; and uniformly mixing the whole granules with xylitol granules, sucralose and silicon dioxide, and then sub-packaging same, so as to obtain the solid beverage. The solid beverage is easy and fast to dissolve, does not separate, and tastes refined and smooth.

Abstract: Disclosed is a catering truck on an aeroplane. Drink pots are designed on the catering truck. Each drink pot holds a different liquid drink. Each drink pot corresponds to one faucet. A flight attendant pours drinks for passengers by means of a faucet switch. Four technical solutions are included: a catering truck travelling on the corridor floor of an aeroplane; a catering truck travelling while hanging on a central rail in the ceiling right above the corridor floor of an aeroplane; a catering truck travelling while hanging on a side rail in the ceiling oblique above the corridor floor of an aeroplane; and a catering truck travelling while hanging on a rail on the luggage rack of an aeroplane. Meanwhile, further proposed is a design concept of storing a catering truck in the ceiling or the luggage rack.

Abstract: An external electronic viewfinder includes either the lens assembly of the eye-level zoom-in viewfinder (1, 2) and the miniature camera (5), or the lens assembly of the eye-level zoom-in viewfinder (1, 2), the miniature camera (5) and the movable reflector (3). When electronic view-finding is not needed, the viewfinder is used as an optical eye-level zoom-in viewfinder. When it is used as an electronic viewfinder, it is OK to directly move the miniature camera (5) to the optical axis. It is also acceptable to move the movable reflector (3) to the optical axis so that it reflects the images on the miniature camera (5) which then sends them to external display devices (6) via wired or wireless linkage. The photographer can view, compose, focus and remote capture by observing the external display devices.

Abstract: A stapler with a binding scale-plate includes a base and a staple distortion part grade. The binding scale-plate is designed on the base of the stapler, which can be a single unit or an assembled unit. The binding scale-plate is installed on the stapler base via a rotation axis, and is retrieved to the stapler base when not used and when used, the binding scale-plate is rolled out to one side of the base at a 90-degree angle along the rotation axis. In this way, the binding scale-plate is formed, with the length greater than the width of the base, this will serve as reference for determining binding sites of staples for users.
