Abstract: A bioculture meat device includes a culture medium conditioning tank (1), a cell proliferation tank (2), a muscle separating tank (3), a compression forming device (4), and a control system. The control system is divided into a culture medium regulation and control system (51) for controlling the culture medium conditioning tank (1), a cell proliferation control system (52) for controlling the cell proliferation tank (2), and a muscle collecting and shaping control system (53) for controlling the muscle separating tank (3) and the compression forming device (4). Different from traditional manual production, the device controls a culture environment through automatic equipment, realizes automatic integration from culturing to processing a finished product, improves the production capacity, and reduces the cost.

Abstract: The present disclosure provides a special culture apparatus for a 3D biological tissue, and a method for preparing block-shaped cultured meat. The special culture apparatus for a 3D biological tissue includes: a 3D biological tissue culture tank for accommodating a 3D biological tissue, and a liquid storage tank for containing a culture medium; the 3D biological tissue culture tank is connected to the liquid storage tank by means of a pipeline to form a circuit for the culture medium to circularly flow; and an opening of the 3D biological tissue culture tank is provided with a sealing plug, an inner side of the sealing plug is provided with a plurality of culture medium infusion needles that penetrate the 3D biological tissue when in use.

Abstract: The present disclosure discloses an operating method of a wind power jib of a crane and a crane, and relates to the field of engineering machinery. The method includes the following steps: rotatably connecting a main boom and a wind power jib; overturning the wind power jib to a first preset position by using a traction means of the crane; contacting a cushioning member with the wind power jib provided at the first preset position; further drawing the wind power jib to overturn to a second preset position; releasing the traction means, such that the wind power jib overturns automatically under the effect of self gravity and a cushioning member until the wind power jib is overturned in position.

Abstract: With a half press of a shutter button, a focus lens is moved from a near distance end to a far distance end of a predetermined search range, and AF evaluation values are calculated. Based on the AF evaluation values, a maximum evaluation value and a first lens position corresponding to the maximum evaluation value are detected. If the maximum evaluation value is larger than a threshold value and the first lens position is not located at the near distance end or the far distance end, the first lens position becomes an in-focus position. If the first lens position is, for example, at the near distance end, the focus lens is moved within an extended search range set on the near distance side, and the maximum evaluation value is obtained. A second lens position corresponding to the maximum evaluation value becomes the in-focus position.

Abstract: The photographic apparatus according to the present invention comprises a posture detecting device which detects the posture of a body of the photographic apparatus, a store instructing device which instructs storing of a posture detected by the posture detecting device, a posture storing device for storing the posture detected by the posture detecting device in accordance with an instruction from the store instructing device, a discrepancy extent computing device which compares the posture stored by the posture storing device and the current posture detected by the detecting device, and computes the extent of any discrepancy of the current posture from the posture stored by the posture storing device, and a correction information generating device for generating correction information for correcting the current posture to the posture stored by the posture storing device on the basis of the extent of the discrepancy computed by the discrepancy extent computing device.
