The invention relates to a sensor and assembly comprised in a housing for a hand-held and hand-operated printing device controlled by a processor, and a method therefor. It provides that the assembly comprises an arrangement and a method for preventing skew and cutting of printed images.

The invention discloses an air suction / exhaust method and structure of a V-shaped box facial tissue folding machine. The two ends of each tissue folding roller with a cutter on the roller surface are provided with air suction control ports in mutual communication respectively; air suction is performed at the air suction control ports at the two ends at the same time to form a negative pressure and absorb the facial tissue; and thus the processes of tissue feeding, cutting and folding are realized on the same tissue folding roller. The structure disclosed by the invention comprises two parallel tissue folding rollers and two cutter shafts; the roller surface of each tissue folding roller is axially provided with a cutter corresponding to the cutter shaft; each side of each tissue folding roller is provided with a tissue feeding air suction control port, a tissue folding air suction port and a corresponding air valve; the tissue feeding air suction control port and the tissue folding air suction control port are mutually communicated through an air suction channel; and air suction holes are correspondingly communicated with the corresponding air suction channel to form a structure realizing respective and synchronous air suction of the tissue feeding air suction control port and the tissue folding air suction control port on the two sides of the tissue folding roller. The invention has the advantages of high efficiency, high tissue folding precision, low energy consumption and low production and operation cost.

A scalpel for cutting soft tissues of the body with an abrasive trailing surface. The abrasive trailing surface reduces distinct scar formation by supporting wound healing. The scalpel can be mounted upon a traditional handle. It may also be implemented as a reciprocating saw, as a rotary drill and reciprocating saw, or as a circular and reciprocating saw.

The invention discloses a device for early warning of structure damage according to stress monitoring, comprising a mobile terminal, a data processor and a netting. A top frame is connected to the topof the netting, a bottom frame is arranged at the bottom of the netting, cables are connected to the lower edges of the bottom surface of the bottom frame and the outer periphery of the top frame; each cable is braided with multiple strands, and is braided with an optical fiber, and the bottom bend of the optical fiber is sleeved with a sheath; the sheath comprises a cap, the cap is connected with a casing through thread, anti-wear seal gaskets are symmetrically arranged on the top of the cap, at least three fixing shafts are arranged longitudinally inside the casing, each fixing shaft is sleeved with a rotary shaft, and a rubber layer is attached to the inner wall of the casing. Tension of the cables is monitored in real time by the device according to impact to the cables from sea waveand sea current, the tension to the cables is determined according to monitored data, and economic loss due to breakage of the cables caused by stress, which excesses the bearing capacity, of the cables is avoided.

The invention discloses a novel schoolbag for elementary school students. The novel schoolbag comprises a bag body (1), bag straps (2), a stationery pocket (3) and sundry net bags (4); a plurality of separation plates (5) are arranged in the bag body (1) to divide the bag body (1) into a plurality of spaces, and a soft pad (6) is mounted at the bottom of the bag body (1). The bag straps (2) are located on the back face of the bag body, a pull rod (7) is mounted on the back face of the bag body, and plastic wheels (8) are mounted at the lower end of the pull rod (7). The stationery pocket (3) is located on the outer side of the bag body (1); the sundry net bags (4) are located on the left side and the right side of the bag body. According to the novel schoolbag, the separation plates are arranged to divide the bag body into the spaces, and therefore multiple books can be placed in different spaces. The books are protected through the soft pad at the bottom of the bag body, and stationery can be placed in the stationery bag on the outer side of the bag body. Water bottles, umbrellas and other articles can be placed in the sundry net bags; especially the pull rod and the plastic wheels are arranged, the schoolbag can be dragged, and loads on the shoulders of a child can be relieved.

The invention discloses a processing method for a gasket of a deck cabin of a vessel. The processing method comprises a measuring method for a gap between the deck cabin of the vessel and a deck cabin base, and an adjusting method for processing data. Through the adoption of the processing method disclosed by the invention, the gasket of the deck cabin can be better and faster mounted, the contact area of the gasket, the deck cabin and the deck cabin base can be increased, and the service life of the gasket of the deck cabin is prolonged. The processing method disclosed by the invention is simple in technology, the rejection rate of the gasket of the deck cabin can be effectively reduced, and the situation that the quality is reliable is guaranteed.

While conveying paper, the paper is folded in a first folding pattern at right angles to the conveyance direction (S1). By bending and rupturing the folded paper, one or multiple perforation lines corresponding to a second folding pattern that is at right angles to the fold(s) are formed in the paper (S2). While conveying the paper with perforations in a direction at right angles to the previous conveyance direction, the paper is folded in the second folding pattern along the perforations, thereby forming a quire (S3).
