A tube reduction apparatus uses a pair of plates, each of the plates providing an X-shaped aperture therein. The X-shaped aperture comprises two pairs of opposing slots, and each slot provides a pair of opposing grooves. The grooves are oriented at right angles to the slots. The pair of plates are in face to face contact with the X-shaped apertures, grooves and slots aligned. A set of four wheels are mounted on transverse axles which are captured in the grooves with the wheels positioned in the slots. A V-shaped concave annular face has an has a semi-circular annular notch at its apex. The four wheels are positioned such that their edges are in mutual adjacency forming a square passage therebetween them.

The invention relates to a novel host of a split-type panel computer. According to the invention, the split-type panel computer adopts a parted structure composed of the host and a hand-held terminal. Based on the characteristic that the host and the hand-held terminal are apart, the host can be in various forms and has functions of ornamental articles, additions, gifts, toys, including some built-in special application functions.

The invention discloses an ion mobility spectrometer and a migration tube thereof. The migration tube includes a curved base tube. Implementing the technical solution of the present invention, since the migration tube of the ion mobility spectrometer adopts a curved base tube, the structure and size are more compact than the linear migration tube, and while realizing the miniaturization of the ion mobility spectrometer, it is ensured that The length of the transfer tube is increased, thereby effectively improving the resolution and sensitivity of the ion mobility spectrometer. In addition, because the overall shape of the curved transfer tube is more square, the design of its peripheral support system (such as temperature control system, etc.) is easier and the work effect is better.

The invention relates to a continuous foaming device for amino sound-absorbing cotton. The continuous foaming device comprises a foaming mold, a microwave system, a foaming air supply and air outlet system and a foaming unit of a foamed stainless steel shell, wherein the microwave system is arranged on the outer side of the foamed stainless steel shell, and the foaming air supply and air outlet system is arranged on the outer side of the foamed stainless steel shell; the microwave system comprises a power supply, a magnetron and a microwave transmission pipeline, and the tail end of the microwave transmission pipeline enters the interior of the foamed stainless steel shell to be located between the foamed stainless steel shell and a top plate of the foaming mold; and the microwave system further comprises strip-shaped distributors which are arranged in a cavity at the tail end of the microwave transmission pipeline, the cross sections of the strip-shaped distributors are isosceles triangles, and the strip-shaped distributors are arranged to enable wave-facing surfaces of the strip-shaped distributors to uniformly separate microwaves and transmit the microwaves to the two sides. According to the continuous foaming device, the plurality of wedge-shaped strip-shaped distributors with isosceles triangles are arranged in the cavity at the tail end of the microwave transmission pipeline, the microwaves are uniformly separated and transmitted to the two sides, so that the microwave uniformity is effectively improved.

A method of fabricating an epitaxial layer includes providing a substrate. The substrate is etched to form at least a recess within the substrate. A surface treatment is performed on the recess to form a Si—OH containing surface. An in-situ epitaxial process is performed to form an epitaxial layer within the recess, wherein the epitaxial process is performed in a hydrogen-free atmosphere and at a temperature lower than 800° C.

A slat connecting system is provided for a roll-up truck bed cover comprising an array of a plurality of contiguously arranged elongated slats. The elongated slats are pivotably hinged together, wherein an elongated slat comprises a main slat body having a first elongated edge and an opposite second elongated edge, a first elongated hinge member is provided in the vicinity of the first elongated edge along its length, and a second elongated hinge member is provided in the vicinity of the second elongated edge along its length, wherein the first elongated hinge member of a slat of the array of the plurality of contiguously arranged elongated slats is configured for being pivotably interconnected to the second elongated hinge member of the adjacent slat of said array.

The invention discloses an automatic green brick cutting device. The automatic green brick cutting device comprises a clay strip conveying mechanism, a moving mechanism and a cutting mechanism arranged on the moving mechanism, wherein the cutting mechanism cuts clay strips and pushes the cut clay strips away in the state that the relative speed of the moving mechanism and the clay strip conveying mechanism is zero. With the adoption of the structure, the automatic green brick cutting device and the cutting method have the advantages as follows: (1), conveying is not required to be stopped when the clay strips are cut in the clay strip cutting process, and the clay strips are continuously and automatically cut off; (2), the relative speed of the cutting mechanism and the clay strips is zero in the moving direction of the clay strips, so that clay strip green bricks are square during cutting, the whole mechanism is compact, and the small area is occupied.
