Abstract: A cemented carbide includes a plurality of tungsten carbide particles, and a binder phase including Co. The binder phase further includes Cr. A region in a cross section of the cemented carbide where a distance X between surfaces of the tungsten carbide particles adjacent to each other having an opposing surface length L of 100 nm or more is 5 nm or less is a WC/WC region. A peak value of atomic percentage of Cr obtained by an elemental analysis in a transverse direction from one tungsten carbide particle to the other tungsten carbide particle in the WC/WC region is a Cr value, and a peak value of atomic percentage of Co thus obtained is a Co value. A ratio of the Cr value and the Co value (Cr value/Co value) is a Cr/Co ratio, and the Cr/Co ratio is larger than 1. A cutting tool includes the cemented carbide.

Abstract: An enclosing-sealing apparatus includes a flap opener that opens a flap of an envelope while the envelope is conveyed to an enclosing position. A first envelope detector is disposed upstream from the flap opener in an envelope conveyance direction and detects both ends of the envelope in the envelope conveyance direction. A second envelope detector is disposed downstream from the flap opener in the envelope conveyance direction and detects both ends of the envelope in the envelope conveyance direction in an open state in which the flap opens. A controller determines the open state of the flap based on a first detection result sent from the first envelope detector and a second detection result sent from the second envelope detector. The controller performs troubleshooting for enclosing the enclosure into the envelope if the controller determines that the open state of the flap is faulty.

Abstract: An envelope processing apparatus for enclosing an enclosure into an envelope conveyed to an enclosing position includes a conveyance roller that conveys the envelope to the enclosing position. A first envelope length calculator calculates a first envelope length of the envelope in an envelope conveyance direction in which the envelope is conveyed in a close state in which a flap of the envelope closes.

Abstract: An envelope processing apparatus includes a flap opener, a first envelope detector, a second envelope detector, and circuitry. The flap opener opens a flap of an envelope during conveyance of the envelope in an envelope conveyance passage in which the envelope is conveyed to an enclosing position. The first envelope detector detects the envelope at a position upstream from the flap opener in a conveyance direction of the envelope. The second envelope detector detects the envelope at a position downstream from the flap opener in the conveyance direction. The circuitry causes the flap opener to execute an opening operation of the flap of the envelope conveyed to the enclosing position and causes the flap opener to execute the opening operation of the flap again when an opening-and-closing state of the flap determined based on detection results of the envelope by the first and second envelope detectors is abnormal.

Abstract: An enclosing device to insert an enclosure into an envelope conveyed to an enclosing position includes an envelope conveyor and an enclosing unit. The envelope conveyor conveys the envelope to the enclosing position. The enclosing unit opens a frontage of the envelope such that the enclosure is inserted into the envelope that has reached the enclosing position and includes an opening amount adjuster to adjust an opening amount of the frontage when the enclosure is inserted into the envelope.
