摘要： A receiving and sending integrated chip for an OLT, which relates to the field of integrated circuits and optical communications. The present invention arms at resolving the problem of high production costs and long production cycle due to the fact that the functions of a limiting amplifier and a laser driver of a traditional OLT end optical module based on a GPON and an EPON are implemented by means of two circuit chips. The present invention provides two solutions. The first solution is designed based on the EPON, a transmitter threshold value configuration mode is that the threshold value configuration is implemented after an upper computer and a slave I2C circuit in the chip cooperate to complete electrifying, and LOS signal determination in a receiver can be automatically reset by means of a chip internal module. The second solution is designed based on the GPON, the transmitter threshold value configuration mode is that the threshold value configuration is implemented after the upper computer and the slave I2C circuit in the chip cooperate to complete electrifying, LOS signal determined in the receiver can be automatically reset by means of the chip internal module and can also by manually reset by means of chip external RESET signals in cooperation with a corresponding peripheral circuit, and LOS and SD signal output selection pins are arranged.

摘要： A high temperature resistant polyimide film and its preparation method. The present invention relates to a polyimide film and its preparation method and solves the problems of honeycomb's and skin panel's core adhesive—polyimide film with insufficient heat resistance, no climbing of bonding core structure and adhesive fillet formation. The high temperature resistant polyimide film is made by polyimide solution, inorganic filler modifier and interface coupling agent by the steps of: under specific temperature and stirring conditions, adding inorganic filler modifier and interface coupling agent to polyimide solution, stirring to obtain the adhesive agent; filtering and degassing the adhesive agent, casting to a stainless steel drum with carrier cloth and release paper to obtain a self-supporting film; then heating and annealing to obtain the final polyimide film. The present invention is applied to high temperature resistant polyimide film and its preparation method.

摘要： An optimization approach for placement heads tasks assignment of beam-type single-gantry surface mounter is disclosed, building a comprehensive framework that simultaneously achieves all optimization objectives in reasonably short time. Specific steps are as follows: (a) importing user-defined production parameters and forming raw production data, (b) pre-processing the raw production data and obtaining the intermediate production data that facilitates the subsequent processing, (c) verifying the loop condition of the “placement heads tasks assignment”, (d) performing nozzle assignment, (e) confirming all the nozzle assignment exchange possibilities, (f) verifying whether the loop condition of “component allocation” are fulfilled, (g) performing component allocation, and (h) outputting the optimal placement heads tasks assignment results.

摘要： A positioning method of rectangular pin element based on vertex points includes the steps of: obtaining component information and classifying components of a model into two classes; extracting feature descriptors of each vertex point of pin element of the model; obtaining a real image of the component and extracting feature points and an angle between two straight lines where the feature points are located and the positive direction of the X-axis respectively; obtaining a rotation angle and an precise feature point position; determining an precise feature point position corresponding to all the vertex points; obtaining feature descriptor of the vertex points of the actual component pin, a weight value of the vertex points of the component in the model, the vertex points of the actual component corresponding to feature point; and determining the final position of the center of the chip and a precise rotation angle of the chip.

摘要： A heat pump dryer includes a main casing having an air inlet channel and an air outlet channel, a compressor, a first heat exchanger positioned in the air inlet channel, a second heat exchanger positioned in the air outlet channel, a fan provided in the air inlet channel, and an energy efficient heat exchanger. The energy efficient heat exchanger has a first portion partially exposed to the air inlet channel, and a second portion partially exposed to the air outlet channel. Air is arranged to enter the air inlet channel to sequentially perform heat exchange with the first portion of the energy efficient heat exchanger and the first heat exchanger. Air passing through the air inlet channel is arranged to enter the air outlet channel to sequentially perform heat exchange with the second portion of the energy efficient heat exchanger and the second heat exchanger.
