A content presentation system, a content presentation device, and a content presentation method that reduce a burden on a user and present suitable contents to the user with high accuracy are provided. The present technology provides a content presentation system including a computer device that holds content information associated with emotion information indicating an emotion of a user, in which the computer device at least includes a machine learning model that, on the basis of a plurality of pieces of content information presented to the user corresponding to desired emotion information indicating emotion information desired by the user and content information selected by the user from the plurality of pieces of content information, performs machine learning so as to present the content information suitable for the emotion information.

Content presentation system, content presentation device, and content presentation method

A method of drawing an optical fiber in which a glass optical fiber is drawn while fusing by heating and pulling by a pulling mechanism one end of an optical fiber preform made of glass, includes drawing the glass optical fiber from the one end of the optical fiber preform while controlling a drawing speed to make an external diameter of the glass optical fiber larger than an external diameter of a product-to-be glass-optical fiber to be used to manufacture a product. The method includes adjusting an external diameter of the glass optical fiber to an external diameter passable through a die for forming a coating. The method also includes arranging the die around the glass optical fiber having the external diameter passable through the die.

Method of processing glass optical fiber and method of drawing optical fiber

A method of processing an optical fiber includes introducing fiber that has passed a pulling mechanism to a shredding unit with an introducing unit. The introducing unit includes a movable unit including a notch configured to fit with a capstan roller included in the pulling mechanism, a sliding mechanism that attaches the movable unit slidably with respect to a main body of the introducing unit, and a restoring mechanism configured to restore the movable unit to an initial position when the movable unit has slid. The method includes shredding the fiber introduced by the introducing unit into fiber pieces, and suctioning, carrying, and collecting the fiber pieces. A method of drawing an optical fiber includes drawing the fiber while controlling a drawing speed, adjusting a diameter of the fiber to a diameter passable through a die, and arranging the die around the fiber having the diameter passable through the die.

Apparatus for and method of processing glass optical fiber, method of manufacturing and method of drawing optical fiber

An apparatus includes: an introducer to introduce a glass optical fiber that has passed a pulling mechanism pulling, to draw the glass optical fiber, one end of an optical fiber preform that has been fused by heating; a shredder including a casing connected to the introducer and a shredding mechanism to shred the glass optical fiber introduced by the introducer in the casing into glass optical-fiber pieces; a pipe connected to the casing of the shredder and to carry the glass optical-fiber pieces; and a suction unit connected to the pipe and to suction the glass optical-fiber pieces via the pipe.
