The base structure for a device such as a hard disk drive and the like, in which the rigidity thereof is secured or the weight thereof is reduced by using various base reinforcing parts and reinforcing part processing members while the manufacturing costs of the base structure are reduced.

The invention provides a method for treating stainless steel pickling wastewater and relates to the field of environmental protection. The method comprises the following steps: adjusting the pH of the flushing water to 1-2, adding the first defluorination agent and the second defluorination agent, then standing and filtering to obtain a filter cake and filtrate; adjusting the pH of the filtrate to 2-3 , add iron-removing flocculant, then stand still and filter to obtain filter cake and filtrate; adjust the pH of the filtrate to 4-5, add chromium-removing flocculant, then stand still and filter to obtain filter cake and filtrate; adjust the pH of the filtrate to 6-7, add nickel-removing flocculant, then stand still and filter to obtain filter cake and filtrate; adjust the pH of the filtrate to 7-8, then undergo membrane treatment, concentrated water is treated by three-effect evaporation, and the concentrated liquid is cooled and crystallized. Carry out harmless treatment. Please provide the method to separate and extract each element in the flushing water one by one, so as to achieve the purpose of comprehensive utilization of resources and environmental protection.

A low cost video recording apparatus for one time recording on a recording medium, comprises a casing (15) which houses a video cassette tape, a lens (1), a microphone (16), a colour CMOS sensor, a signal processing module, a write head and a drive unit, in operational relation to each other. Also provided is a view finder (21) and an operating switch (22). The casing (15) has formed thereon a tear strip (20) used for opening the casing once recording has been completed. Removal of the cassette tape also involves disabling of tape guide components. Since one time recording only is possible with no playback or rewind, the life requirements for the various components can be considerably reduced.

The invention discloses a multi-pylon multi-span lifting cable crane. The crane comprises M pylons, N lifting spans connected to the M pylons sequentially, bearing cables, an overhead crane and lifting appliance assembly, traction systems, lifting systems and anchorage systems, wherein each pylon comprises a cable tower and a main tower arranged at the top of the cable tower, and a cable saddle structure for supporting the corresponding bearing cable is arranged at the top of the main tower; two ends of single bearing cable are used for being connected with the anchorage systems located on both banks; one lifting span is formed between every two adjacent pylons, and at least two lifting spans are connected to form a multi-pylon multi-span structure; the traction systems are used for pulling the single overhead crane and lifting appliance assembly to move between the adjacent lifting spans, and the lifting systems are used for lifting materials through the overhead crane and lifting appliance assembly; N and M are both natural numbers, M is larger than or equal to 3, and N is equal to the difference between M and 1. Therefore, multiple lifting spans are formed by arranging multiple pylons, and compared with the conventional double-pylon single-span lifting cable crane, the height of each pylon is reduced substantially and controlled effectively.

The invention relates to a combination method for three-dimensional garage groups. The three-dimensional garage groups include: a plurality of single deep well type three-dimensional garages. The single three-dimensional garages are linearly arranged and combined into a single-row three-dimensional garage group through one by one. The single-row three-dimensional garage group is combined into a double-row three-dimensional garage group or a three-row three-dimensional garage group. Two single-row three-dimensional garage groups are staggered by one carport, and a second row B and a first row A are staggered by one carport and are combined into the double-row three-dimensional garage group, or into the three-row three-dimensional garage group. The three-row three-dimensional garage group is composed of A, B and C three rows of single-row three-dimensional garage groups, wherein the second row B and the first row A are staggered by one carport, a third row C and the second row B are staggered by one carport, so that the three-row three-dimensional garage group is formed. The invention has advantages that the garage group has very high capacity, and the area of a basketball court can store 500 vehicles; each three-dimensional garage has an independent collector lane, so that the vehicles can go in and out conveniently and quickly, thereby relieving the pressure for car parking.
