The invention discloses a preparation method of a hollow nickel cobaltate nano polyhedron. The method comprises the following steps: (1) mixing an organic metal framework complex ZIF-67 and an alcoholic solution of nickel nitrate uniformly, and reacting at the temperature condition of 80-100 DEG C; (2) cooling to room temperature after reaction, collecting precipitate, cleaning by ethyl alcohol or other non-polar solvents, centrifuging, removing the solvents, and carrying out vacuum drying so as to obtain a hollow nickel cobalt hydroxide polyhedron; and (3) annealing the hollow nickel cobalt hydroxide polyhedron in air heating so as to obtain the porous nickel cobaltate nano hollow polyhedron. The method is simple to operate, and is environmentally friendly, and the mold plate removing process is omitted; the hollow obtained nickel cobaltate nano polyhedron has the relatively high specific surface area, relatively low mass transfer resistance and relatively excellent structure stability; as an electrode material of the lithium ion battery, the hollow nickel cobaltate nano polyhedron is superior to an existing transition metal oxide electrode material in cost and performance.

The invention belongs to the technical field of radar weak and small target detection and tracking, and particularly relates to a method for conducting before-detection tracking on a weak and small target in a strong-clutter environment based on dynamic planning. The method for conducting before-detection tracking on the weak and small target in the strong-clutter environment based on dynamic planning includes the first step of preprocessing echo data received by radar to obtain a processed distance-doppler two-dimensional image, and the second step of constructing a complex number likelihood ratio function according to the distance-doppler two-dimensional image, taking the complex number likelihood ratio function as a value function for dynamic planning, and conducting before-detection tracking on the target according to a dynamic planning method so as to obtain the target track.

The invention discloses a 3D printing method for an embedded electronic product and a 3D printer. After each layer of structure material is printed, a layer of release material is arranged around a support reserved position in a jet printing manner, support printing is conducted, and when the set of structure layers are printed, supports of reserved holes and grooves are removed, an electronic component is embedded, printing of the set of electric conduction layer structure, jet printing of electric conduction circuits and jet printing of dielectric materials between the electric conduction circuits are sequentially conducted, the process is repeatedly conducted till the last set of electric conduction layer structure is printed, and the electronic product is packaged through printing structure materials. The release material is introduced between the structure material and a support material, the support material is easy to remove, on one hand, removal of the supports through an ultrasonic alkaline solution is avoided (a traditional support removing technology is not allowed to be adopted in the embedded electronic product), and on the other hand, influences on a printed electric conduction circuit from support removal are avoided. The problem about support removal in the embedded electronic product manufacturing process is effectively solved.

A child proof and tamper evident container (C) includes a pail (10) and a screw top cover (12) screwed onto the top of the pail to enclose contents of the pail. A latching mechanism (18) is formed on the pail. A plurality of tamper evident tabs (26) and second a child proof tab (14) are formed on the cover. Both types of tabs means engage the latching mechanism as the cover is screwed onto the pail. The one tab provides an indication as to whether or not the contents of the container have been tampered with, and the second tab prevents a child from removing the cover and opening the container.

An attachment device for securing a trim cover to foam pad. The attachment device includes an elongated attachment component coupled to the trim cover and a base component disposed within the foam pad. The attachment component includes an outwardly protruding barb and a key pad at a distal end thereof. The base component includes a retaining element having a pair of spaced apart fingers defining a gap there between and a keyway at the bottom of the retaining element between the fingers that is adapted for receiving the key. The key of the attachment component is disposed in the keyway of the retaining element and one of the fingers interacts with the barb to prevent removal of the attachment component from the base component.

A semiconductor device production method which includes steps of: preparing a wafer on which multiple integrated circuits are formed on a principal face; forming a rewiring which is electrically connected to the integrated circuits via a pad electrode; and dicing the wafer after forming an electrode terminal on the rewiring, including steps of: forming a first resin layer by sealing at least the rewiring and the electrode terminal formed on the principal face of the wafer with a first resin; processing a first dicing from a back face of the wafer to the principal face of the wafer or halfway to the first resin layer when the first resin layer is formed; forming a second resin layer by sealing a cut line outlined upon the first dicing and the back face of the wafer continuously with a first resin; and processing a second dicing while leaving the second resin layer which covers a side face outlined upon the first dicing.

The invention relates to an oral proliposome containing atorvastatin calcium and a preparation method of the oral proliposome. The oral proliposome comprises the following components: 0.5%-10% of the atorvastatin calcium, 10%-30% of phospholipid, 2%-10% of poloxamer, 50%-87.3% of absolute ethanol and 0.2%-3% of a stabilizer. The preparation method comprises the following steps: adding the atorvastatin calcium, the phospholipid, the poloxamer and the stabilizer into the absolute ethanol solvent, mixing in the absence of water, and dissolving the mixture into a clear anhydrous solution so as to obtain an atorvastatin calcium proliposome preparation. The proliposome can be quickly self-assembled into the medicated proliposome preparation with a proper particle size and high encapsulation efficiency after being diluted by a proper hydration medium before use and is used for oral administration, the operation is easy and convenient, and the oral administration mode can be easily accepted by patients.

Provided is a developing cartridge, which can be removably mounted in an image forming apparatus. The developing cartridge comprises: a developer carrier for developing an electrostatic latent image formed on an image carrier; a frame for supporting the developer carrier; a protective member removably mounted on the frame in the axial direction of the developer carrier so as to protect the developer carrier; a container unit for containing a developer to be fed to the developer carrier; a sealing member for sealing an opening, through which the developer is fed from the container unit to the developer carrier; and a grip portion formed at one longitudinal end of said sealing member so as to be gripped when the sealing member is removed from the opening. The grip portion can take a first position, which is located on a moving locus when the protective member is removed from the frame, and a second position, which is deviated from the moving locus.
