The invention discloses a milling cutter for a processing flexible board, which comprises a cutter handle (1). One end of the cutter handle (1) extends to form a milling cutter head (2). Two spiral grooves (3) in the same spiral direction are molded on the surface of the milling cutter head (2) to form milling edges. A V-notch cutting surface is arranged at the end of the milling cutter head (2). A chamfer is arranged at the end part of the cutting surface to form a chamfering edge. The spiral angle omega of each spiral groove (3) is 28-32 degrees. The milling cutter solves the problems of poor rigidity and poor cutting performance of the existing milling cutter used for processing flexible circuit boards, and is particularly suitable for processing blind grooves with chamfers on plates such as aluminum substrates, copper substrates, flexible boards, Teflon plates and polytetrafluoroethylene plates.

The second bevel gear rod and the third bevel gear rod meshed with it, the first motor is fixedly installed on the top of the box, the output end of the first motor is fixedly connected with the third bevel gear rod, and a stirring mechanism is installed in the cleaning tank, stirring The mechanism is connected with the third bevel gear rod through the lifting mechanism, the filter plate slidingly connected with it is installed at the bottom of the box body, and the water outlet is opened at the bottom of the box body; by combining cleaning and drying, the invention makes the lifting mechanism cooperate with the stirring mechanism, Filtration is performed directly after cleaning, the structure is simple, the control is stable, the efficiency of cleaning and drying is improved, multiple treatments of Chinese medicinal materials are avoided, and the processing efficiency of Chinese medicinal materials is improved.

A recorder of X-ray photoelectronic hologram for quickly real-time observing the 3D ultramicro structure of biological specimen in the natural state is disclosed. Its record method includes such steps as focusing X ray by waveband plate, filtering by pinhole diaphragm, overlap interference of the object beam passing through the opaque or semi-transparent part of specimen with the reference beam passing through its transparent part, converting the X-ray holography to photoelectronic interference field by photoelectronic cathode, accelerating, amplifying, sending to the computer, data processing and reproducing image.

The invention discloses a method for measuring and locating external thread parameters of an oil pipe based on a profile, which determines the external thread profile of the oil pipe to be tested, uses image processing technology to obtain flank line data and fits a straight line equation, according to the profile of the external thread to be measured and The difference of the reference contour positioning line is adjusted to obtain the angle, and the position of the oil pipe to be tested is adjusted to complete the positioning. The invention is suitable for determining the measurement and positioning of various parameters by using the external thread profile of the oil pipe, and is not limited to contact measurement and non-contact measurement.

The invention discloses a negotiation method for IPv6 address compression capability, a network system and a terminal node. In this method, each terminal node sends an initial notification message containing priority to the terminal node connected to itself, so that each terminal node can compare the priority and determine the controlling terminal node and the non-controlling terminal node; the non-controlling terminal The node reports the compression coding method it supports to the control terminal node; the control terminal node determines the preset compression coding method, and notifies the non-controlling terminal node through the compression feedback message; all terminal nodes only load the instructions corresponding to the preset compression coding method and The protocol stack is assembled into the memory, so as to compress and encode the IPv6 address by using a preset compression encoding method. The technical scheme provided by the invention reduces the memory consumption of the terminal nodes, saves processor resources, and simplifies the complexity of network operation and management.
