Abstract: An object of the present invention is to reduce an error between an actual machine and a simulation by removing the influence of overlearning of an adjustment by a mathematically-described function, and to optimize automatic operation control of the machine. An automatic operation control system for controlling an automatic operation of a machine sets a first model showing a relation between a control signal string input to the machine on the basis of a mathematically-described function and data output from the machine controlled in accordance with the control signal string. In a learning process including learning the automatic operation control of the machine, the system executes learning using the first model until a first condition is satisfied.

Abstract: A vertebral surgery instrument includes: an engagement part for engaging with a pair of opposing parts provided on or attached to a vertebral implant in a state in which the vertebral implant is fixed to a vertebra, the pair of opposing parts forming a slit into which a fixation rod for fixing a plurality of vertebrae to each other is to be inserted; and a pair of guide parts that are provided integrally with or attached to the engagement part. The pair of guide parts are formed extending so as to separate from each other toward a side on which the fixation rod is to be inserted, in a state in which the engagement part is engaged with the pair of opposing parts, and the slit and a guide passage that is formed between the pair of guide parts are in communication with each other.

Abstract: A video display apparatus includes a display section that carries out a display process based on a drive signal and a drive section that outputs to the display section a first drive signal based on a video signal having undergone video processing in a first video processing section at a fixed cycle and a second drive signal based on a video signal having undergone video processing in a second video processing section at the same cycle as the cycle at which the first drive signal is outputted but at timing shifted from the first drive signal by one-half the cycle. When the video signals contain two-dimensional video images, the first video processing section produces a video signal for two-dimensional video images and the second video processing section produces a video signal for black screen insertion.
