Abstract: The invention discloses a cell culture and experiment device used in the field of biological and genetic engineering experiment apparatus, comprising a cent distribution compartment, a culture compartment, a treatment compartment, and pipelines for delivering liquid between the central distribution compartment and the culture compartment and between the central distribution compartment and the treatment compartment. The central distribution compartment is equipped with a distribution chamber and a piston which can be moved forward and backward in the distribution chamber to alter the working volume of the distribution chamber. At the bottom of the distribution chamber, the central distribution compartment is equipped with a distribution valve controlling the connectivity between the distribution chamber and any of the channels.

Abstract: The present invention discloses a device for cell culturing and processing, applicable in the field of biological and genetic engineering experiments, which comprises at least one central distribution compartment, at least one incubation compartment; at least one processing compartment, a number of ducts to transfer fluids between said compartments, wherein a distribution cavity and a piston capable of moving back and forth in said distribution cavity for altering the operational volume of said distribution cavity are provided within said central distribution compartment, and a distribution valve controlling the connection between said distribution cavity and said ducts is provided at one end of said distribution cavity within the distribution compartment. During operation, cells grow and multiply in a cell suspension contained in the incubation compartment.

Abstract: The present invention discloses an optical system for 3D printing and a control method thereof. The system comprises a laser device, a beam expanding system, a beam splitter, a spatial light modulator and a focusing system. The spatial light modulator is connected with a computer and configured to generate a modulation pattern after receiving the target modulation pattern generated by the computer. A light beam emitted by the laser device is expanded into a parallel light beam by the beam expanding system and then irradiates on the beam splitter. A part of the expanded light beam reaches the spatial light modulator for modulation after passing through the beam splitter, then the modulated light beam is reflected to the beam splitter, and a part of the modulated light beam is focused by the focusing system and then irradiates on a target plane for 3D printing.

Abstract: A method and apparatus for inspecting an object after stamping is described. The method and apparatus comprises determining a temperature distribution of an object after stamping; obtaining one or more thermal images of the object after stamping; and comparing the determined temperature distribution with the obtained thermal images so as to identify defects existing in the object after stamping, in which the difference between the temperature distribution and the thermal images indicates the presence of defects in the object. The method and apparatus can therefore inspect and analysis problems of the object occurred during the stamping process.

Abstract: According to an embodiment of the invention, a mechanical press includes a transmission that comprises a first transmission and a second transmission coupled to the first transmission. The first transmission is for receiving mechanical movement from a first motor and to transmit mechanical movement to a ram. The second transmission is for modifying configuration of the first transmission in response to mechanical movement received from a second motor, and a profile of movement of the ram over a pressing cycle is affected by a profile of movement from the second motor over the pressing cycle.
