The invention belongs to laser technology, and relates to a laser gyroscope annular resonant cavity light path alignment device and method. The laser gyroscope annular resonant cavity light path alignment device comprises a laser device, a light path adjusting component, polarizers, a half transparent and half reflecting mirror, high-reflectivity mirrors, plane mirrors, spherical mirrors, cavity adjusting tools and photoelectric receivers, wherein light output by the laser device enters the polarizers and the half transparent and half reflecting mirror after being adjusted through a light beam adjusting mechanism, then one path of light is directly injected into an annular resonant cavity in the horizontal direction, and the other path of light is reflected by the high-reflectivity mirrors and then is injected into the resonant cavity in the vertical direction. The photoelectric receivers are connected with the resonant cavity through the polarizers and used for detecting output light in the horizontal and vertical direction respectively. The spherical mirrors are dynamically adjusted in real time according to characteristics of linearly polarized light received by the two receiving light paths, annular resonant cavity light path alignment is completed until extinction coefficients of polarized light clockwise and counter-clockwise paths are equal, and tiny non-coplanar light path compensation of the annular resonant cavity is achieved.

The invention relates to the nuclear power technology, and in particular discloses a long-stroke split-type hanging basket assembly capable of controlling deformation. The split-type hanging basket assembly capable of controlling deformation comprises a hanging basket barrel body, a lower reactor core plate which is fixedly connected to the lower end of the hanging basket barrel body, and a baffle which is arranged in the hanging basket barrel body; the baffle is divided into three sections; a forming plate is arranged outside the baffle; by adopting a multi-section short baffle structure, the differential temperature stress of the connection of baffles is effectively reduced and the baffle is convenient to manufacture; by adopting the forming plate, the deformation of the baffle caused by radiation thermal effect is reduced; a cooling agent runner hole corresponding to a fuel assembly is arranged on the lower reactor core plate, and meanwhile, a centering hole for the lower rector core plate and an upper reactor core plate is provided, thus the technical requirement of flow cooling of the cooling agent is met, and meanwhile the centering requirement of the lower reactor core plate and the upper reactor core plate is also met, and besides, the installation becomes more accurate and more reliable.

The present invention provides a photolithographic alignment mark structure and its manufacturing method, which is a multi-level mutual alignment precision pattern structure design and its manufacturing method. When projecting, they are all center-symmetric figures relative to the same center, and the projections of all lithography alignment figures are nested and expanded from inside to outside according to the formation sequence of lithography alignment figures, which can be applied to various lithography processes. According to different needs, it can be matched at will to meet the alignment requirements that are constant and changeable, and can meet the mutual alignment requirements of lithography alignment marks between different layers. At the same time, it can take into account the traditional alignment measurement and 3 exposures, 4 exposures The alignment measurement required for the second exposure, and it saves the space of the cutting line and reduces the cost.

The invention relates to a C-type straightening machine and belongs to the field of ultra-precision machining apparatuses. The C-type mechanical shaft automatic straightening machine comprises an automatic feeding mechanism, a touch screen and operation control panel and PLC electrical control box; an automatic discharging mechanism, a rack, a material pouring mechanism, a work piece clamping mechanism, a straightening mechanism, a measuring mechanism, a straightening moving mechanism and an automatic NG processing mechanism.
