The invention discloses a special-specification vertical goods storing warehouse which comprises a vertical warehouse body, a lifting device and a cargo carrying tray, wherein the vertical warehouse body, the lifting device and the cargo carrying tray are connected; the vertical warehouse body comprises an upper frame, warehouse body pillars connected with the upper frame, rear connecting beams connected with the warehouse body pillars on the rear side, front guide pillars on the two sides and bottom connecting beams connected with the left and right warehouse body pillars; the tops of the front guide pillars are connected with the upper frame, and a cargo carrying tray support seat is arranged between the two warehouse body pillars on the same side; an upper guide wheel set and a lower guide wheel set are respectively arranged at the upper part and the lower part of each front guide pillar, and the lifting device is connected with the upper guide wheel set and the lower guide wheel set. The special-specification vertical goods storing warehouse is compact in structure and convenient in storage, transportation, loading and unloading, improves the efficiency of loading and unloading cargos, reduces labor intensity, and can meet the goods with special size storage requirements such as plates and bar stocks.

The invention relates to a piezoelectric-type touch control faucet, and belongs to the field of automatic faucets. The faucet comprises a first end part, a second end part, a channel and an electrically operated valve; the first end part is connected with a water supply source; the second end part comprises a water outlet nozzle of the faucet; the channel is positioned between the first end part and the second end part, and guides water at the first end part to the second end part; the electrically operated valve is arranged in the channel; a touch area covering a certain region is formed on the outer surface of the channel; a piezoelectric sensor is arranged in the interior of the outer wall of the channel below the touch area; an electronic control unit is connected with the piezoelectric sensor and receives a signal from the piezoelectric sensor so as to control the electrically operated valve to be opened and closed; the electronic control unit comprises an automatic time-delay unit. According to the piezoelectric-type touch control faucet provided by the invention, the control of a touch switch is improved by reducing power consumption, the touch area is defined accurately and is allowed to be controlled by multi-point touch, and the probability of accidental activation is reduced.

The disclosed invention relates to easy-to-use precision tools that locate the mid-line, or center line, of any symmetrical geometric shape, such as triangles, squares, circles, rectangles, parallelograms, trapezoids, and symmetrical polygons. Given two separate points on the edge of a symmetrical geometric shape, these precision tools identify the center line of the geometric shape between those two points, without the need for additional measurements or mathematical calculations. The precision tools can also be used to identify the center points of symmetrical geometric shapes.
