In the array antenna provided with the variable phase shifter P, the variable phase shifter P has a transmission line or a circulator, a variable capacitance capacitor Ct is connected to a ground side of the transmission line or a ground side terminal of the circulator, in the variable capacitance capacitor Ct, a plurality of variable capacitive elements C1 to C5 employing thin film dielectric layers whose dielectric constant varies with the applied voltage are connected in parallel, in terms of DC, and in series in terms of high frequencies between the input terminal and the output terminal. Thus, an array antenna is realized, whose directivity can be controlled adaptively and which is provided with the stable variable phase shifter having little waveform distortion and intermodulation distortion, superior withstanding power, and with low loss even at high frequencies.

A fiber-reinforced composite multi-degree-of-freedom 3D printer and its printing method utilizes the flexibility of the manipulator to perform 3D printing at any angle and any motion trajectory. The 3D printing head installed on it can perform high-strength short-term The 3D printing of fiber-reinforced composite materials can also carry out splicing and weaving of continuous resin-based long fibers, thereby producing a continuous fiber-reinforced resin-based composite material structure. The orientation of the fibers in the middle can realize the rapid manufacture of composite parts with complex structures with specific mechanical, electrical and thermal properties; at the same time, there is no need for pre-customized molds and pre-treated fiber prepreg tapes in this process, not only for large parts It is also suitable for the mass production of small parts, which greatly reduces the manufacturing cost and production cycle, and further promotes the wide application of composite parts.

A liquid crystal device includes a first substrate that has an inner surface on which a pixel electrode is formed; a second substrate that has an inner surface on which a counter electrode constituting a pixel is formed opposite to the pixel electrode; and a liquid crystal layer that is held between the first substrate and the second substrate and has negative dielectric anisotropy. In addition, an alignment control unit for controlling the alignment of the liquid crystal molecules is formed in an area including the center of the pixel electrode on either the first substrate or the second substrate; and the pixel electrode has an approximately polygonal shape, and slits extending from an outer periphery toward the center are formed at corner portions of the pixel electrode.

The invention relates to the preparation technology of metal single crystal, in particular to a method for controlling the transverse crystal orientation of metal single crystal. In the single crystal furnace, a crystal selector and a crystal riser are provided, and the crystal selection method is used to grow single crystal castings; wherein: the crystal riser adopts a rectangular or quasi-rectangular cross-section with a pair of long, relatively parallel opposite sides , so as to introduce an additional directional transverse thermal field to control the transverse crystal orientation of the single crystal during the crystal growth process, use the conventional investment casting method to shape, pour liquid metal, and grow single crystal in the single crystal furnace. The invention can control the lateral crystal orientation of single crystal by introducing an additional directional transverse thermal field in the process of crystal growth and combining the characteristics of preferred orientation of crystal growth.

The present invention provides a device for reliable support and / or transport of tissue grafts or implants that allows for precise microscopical study and / or evaluation and quality control of tissue grafts or implants during treatment and prior to introduction into a living body. The body of the device is a sleeve or shell comprising a rectangular shape preferably having a circular edge and having two opposite openings of different sizes and shapes. The first opening is circular having a diameter suitable for connection to a tube or syringe nozzle. The second opening has an elliptical, circular, biconvex or rectangular shape, preferably with a circular edge in the case of a rectangular shape, the shape of the second opening being small enough to be inserted into a small surgical incision. The transparency and preferably circular, rectangular shape of the device body allows microscopy of tissue grafts or implants within the device and fixation of the location of the tissue grafts or implants during delivery and implantation. The elliptical, circular, biconvex, or preferably rounded rectangular internal shape of the second opening ensures proper positioning of the tissue graft or implant during surgical implantation, thereby preventing issues such as loss of orientation of the tissue graft or implant. The invention also provides an assembly for loading, storing and / or transporting a tissue graft or implant comprising a device according to the invention. The invention also provides a cleaning assembly and a method for preparing a tissue graft or implant.
