An apparatus is arranged to clean a cylinder with cleaning liquid being supplied. The cylinder includes an outer surface to which impurities are adhered. The impurities are removed from the outer surface when cleaning. The apparatus includes a spray bar into which the cleaning liquid is directed with pressure. The spray bar comprises tube means which Includes nozzle holes formed therein for spouting the cleaning liquid. The tube means is formed of elastic material and elastically deformed by the pressure of cleaning liquid to open the nozzle holes and spout the cleaning liquid. The tube means is elastically restored, when the cleaning liquid is not directed with pressure into the spray bar, to close the nozzle holes.

The water-blocking cable paste filling device and filling method of the optical cable strengthening member provided by the present invention can accurately fill the optical cable strengthening member with uniform water-blocking cable paste, and can effectively prevent the unstable water seepage of the optical cable due to uneven filling of the cable paste. problems, and can effectively prevent the situation around the fiber optic cable strength member from being pulled out, thereby improving the quality of the product.

The invention relates to a silicon wafer processing technique in integrated circuit fabrication, in particular to a method for improving gluing capacity, aiming at solving the problem that capacity of spraying on silicon wafer is low in the prior art. The method is as follows: firstly, a processing carrier silicon wafer is placed on a wafer bearing platform; then a gluing nozzle is used for gluing from an initial position corresponding to one end of silicon wafer, and the gluing nozzle does two-dimensional reciprocating scanning between the initial position and corresponding end position at the other end of the silicon wafer in one plane while spraying photoresist, so that the surface of the silicon wafer is uniformly glued. In the invention, the spray type gluing nozzle is adopted to circuitously reciprocate along X axis and Y axis, the scanning path of the gluing nozzle at the periphery of the silicon wafer is shortened, and the gluing capacity is improved.

A filter drip chamber with automatic liquid stopping and automatic exhausting functions belongs to medical apparatus and instruments, a liquid inlet tube is arranged at the upper end of the drip chamber, the lower end of the drip chamber is provided with a drip chamber cover provided with a drip chamber cover bleeder tube and an exhausting tube, a liquid stopping exhausting device is arranged on the drip chamber cover, a filter membrane inner cavity bleeder tube is arranged in the inner cavity of a filter membrane and is communicated with the drip chamber cover bleeder tube, and openings are formed in two side walls of the filter membrane inner cavity bleeder tube; an exhausting pipeline is arranged outside the inner cavity of the filter membrane; the tail end of the exhausting pipeline is communicated with the drip chamber cover exhausting tube; a hydrophilic filter membrane is fixed at the opening surface of the inner cavity of the filter membrane. The filter drip chamber with the automatic liquid stopping and automatic exhausting functions has the advantages of being capable of automatically stopping liquid and automatically exhausting, ensuring drip weight, reducing a filter in a pipeline, and ensuring flow speed and flow rate, and the filter membrane is always positioned in a state of being vertical to the horizontal plane due to the moving up of a filter.

An electrical junction box reduces the number of components to be contained in an electrical junction box and simplifies a structure of the box. The electrical junction box has a casing assembly including an upper casing and a lower casing. A laminated unit including bus bars and insulation plates is contained in the upper casing, while a first printed circuit board, a second printed circuit board and a spacer made of an insulation resin material are contained in the lower casing. The first printed circuit board is disposed on one side of the spacer, while the second printed circuit board is disposed on the other side of the spacer. Shorter size fixing bars and longer size fixing bars project from an inner surface on a top wall of the upper casing. The shorter size fixing bars penetrate the laminated unit, first printed circuit board and spacer. Screws are inserted upward into the shorter size fixing bars via through-holes in the spacer to secure the unit, first printed circuit board,and spacer to the shorter bars. Longer size fixing bars penetrate the laminated unit, first printed circuit board, spacer, second printed circuit board, and lower casing. Screws are inserted upward into the longer size fixing bars via through-holes in the lower casing to secure the unit, first and second printed circuit boards, spacer, and lower casing to the longer bars.

The invention relates to the technical field of integrated cookers. The invention aims to provide an integrated cooker with a flue protection function, so that when the flame is too large, the smoke inlet can be timely closed so as to prevent the flame from being sucked into the integrated cooker. The technical scheme is as follows, the integrated cooker with the flue protection function comprisesan integrated cooker body and a smoke collecting cover arranged on the back side of the top of the main body; a smoke inlet is formed in the smoke collecting cover, and a movable plate is transversely hinged to the upper portion of the smoke collecting cover above the smoke inlet. According to the integrated cooker with the flue protection function, the movable plate can improve the smoke performance of the smoke collecting hood under the normal state, when the flame is sucked into the smoke collecting hood, the effect of closing the smoke inlet is achieved, and further intrusion of flames isprevented.
