The invention relates to a fluid discharging device for separately discharging at least two fluids comprising an inner nozzle for discharging a first fluid and a coaxially arranged outer nozzle for discharging a second fluid. Such a fluid can be liquid or gas or a mixture thereof. Mixtures of liquid or gas comprise fluids having gas as the continuous phase and liquid as the disperse phase (e.g. aerosols) and fluids having liquid as the continuous phase and gas as the disperse phase (e.g. carbonated water). The invention further relates to a device and a method for wet treating a flat disc-like substrate, such as semiconductor wafers, flat panel displays or compact discs utilizing such a fluid discharging device. If in the following the term wafer is used, such disk-like substrates are meant.

A supporting shelf for compact disks includes at least a first tubular housing and a second tubular housing and each has a different inner diameter but a similar cross section. The second tubular housing that has a small inner diameter is disposed within the first tubular housing. Each of the first and second tubular housings has its opening directed upward for readily engagement therebetween. Each of the tubular housings is provided with a plurality of retaining slots at the outer wall and that are parallel to each other, wherein a CD can be readily inserted and retained by the retaining slots of the housings. When a plurality of first and second tubular housings are engaged with each other, a tower-shape supporting shelf can be configured. Each of the receiving slots can be directed upward and angularly. The engagement between the first and second tubular housing can be facilitated through retaining holes and pin-shaft or retaining ball and recess.

A printable sheet including one or more envelope assemblies formed thereon, each having a central body panel, an end flap, a pair of opposing top and bottom panels, a business card removably attached and incorporated into the bottom panel, and a retaining flap. The sheet is capable of being placed in a printer to have images and/or indicia printed on the envelope assemblies. Each envelope assembly is capable can be removed from the printable sheet and folded along weakened lines, and adhered to itself to form a secure sleeve or envelope for holding various items. Each envelope has a retaining flap on the open end that can be tucked into the envelope after insertion of its contents in order to retain the contents, which could either be used or removed if desired. The envelope could be designed to readily hold business card compact discs. The business card can be subsequently separated by the user from the formed envelope.

The invention relates to the technical field of article polishing and grinding equipment, in particular to automatic disc grinding equipment, including a frame, an electric box and a lower turntable assembly are arranged inside the frame, and two symmetrically arranged lifting power assemblies are arranged on the upper end of the frame. The lifting power assembly is provided with an upper polishing assembly, the upper polishing assembly is provided with a control panel, the lower turntable assembly includes a turntable mounting frame and a turntable mounting platform, the lifting power assembly includes a support seat, and the upper polishing assembly Including the upper polishing base, it adopts the grinding disc structure with asynchronous multi-gear meshing transmission and rotation with the main shaft, so that the five sets of fixture discs can rotate at the same time when the large turntable is revolving, and combined with three sets of ordinary power motors to drive the polishing disc to push down using the cylinder The structure is polished, not only can multi-station high-precision polishing and grinding of products at the same time, but also has high production efficiency, low cost, less energy consumption and pollution.

A cartridge drive apparatus for a disc cartridge having upper and lower shells which are separatably joined to each other to form a cartridge body is disclosed, in which a accommodated disc is able to be inserted or ejected by separating the upper and lower shells vertically. The cartridge drive apparatus includes a cartridge holder which, by inserting the cartridge body, has an upper holder supporting the upper shell and a lower holder supporting the lower shell, and a holder moving mechanism which separates the upper holder and the lower holder of the cartridge holder to separate the upper shell and the lower shell and thus is able to allow the disc to be inserted or ejected.

The invention provides a method for manufacturing the structure of a semiconductor device for forming the structure of a dual damascene, which comprises the steps of: providing a front-end device structure; sequentially forming a first metal layer, an etching stopping layer, a second metal layer and a first photoresist layer provided with a first opening pattern on the surface of an intermetallic dielectric layer; firstly etching till that the surface of the etching stopping layer is exposed; removing the first photoresist layer; forming a bottom anti-reflection layer; forming a second photoresist layer with a second opening pattern, wherein the second opening pattern is arranged right above an opening in the second metal layer; secondarily etching till that the surface of the intermetallic dielectric layer is exposed; removing the second photoresist layer and the bottom anti-reflection layer; and thirdly etching till that the surface of the front-end device structure is exposed. Due to the adoption of the method, the bottom anti-reflection coat (BARC)-filling quality can be improved, and the bad influence to a compact disc (CD) caused by overlong BARC etch back time can be avoided.

A downhole oil-water separation device with multistage hydrocyclones in parallel is applicable to a downhole oil-water separation system of a Y-shaped tubular column structure. The downhole oil-water separation device with the multistage hydrocyclones in parallel is provided with a multistage parallel-connected hydrocyclone unit. The quantity of the hydrocyclones can be adjusted according to a practical application situation. Each hydrocyclone is arranged in a tank body along the direction parallel to an axis and is located through a positioning plate, a compact disc, a support disc, an anti-rotation disc and the like. An inlet of the parallel-connected hydrocyclone unit, an overflow flow channel and an underflow flow channel are formed. Each hydrocyclone is compact in structure and easy to install. An electric pump unit and a lifting oil pipe are connected with the upper portion of a three-way piece of the Y-shaped tubular column and the electric pump unit and the lifting oil pipe are connected in a parallel mode. The lower portion of the three-way piece of the Y-shaped tubular column is connected with a cross flow channel body of the downhole oil-water separation device with the multistage hydrocyclones in parallel. The flow channels in the cross flow channel body are respectively communicated with an original oil flow channel and an overflow flow channel of the three-way piece. The multistage hydrocyclones in parallel can be adapted to higher liquid production volume, has higher separation efficiency under the higher liquid production volume, and is applicable to downhole oil-water separation of oil wells with big casing size and the high liquid production volume at sea or land.
