Abstract: A foil transfer device may include a foil applicator to transfer a foil film onto a substrate, and a controller to transfer, using the foil applicator, foil from one foil film onto a first area of the substrate, the foil film having been placed at a first angle relative to the substrate, and transfer, using the foil applicator, foil from the foil film onto a second area of the substrate, the foil film having been placed at a second angle relative to the substrate, the second angle being different from the first angle, the second area being different from the first area.

Abstract: A holding attachment includes a holding portion with a round or substantially round columnar hole shape in which a held portion of a material before cutting is inserted and a mounting portion that is mounted on a work mount of a cutting machine. The mounting portion includes at least one pin that is inserted to at least one pin insertion hole provided in the work mount and at least one engagement portion that is engaged with at least one rotation stopper provided in the work mount. A position reference portion of the material before cutting is recessed from a round or substantially round columnar outer peripheral surface of the held portion. The holding portion includes a fitting portion fit to the position reference portion of the material before cutting.

Abstract: A foil transfer device includes a first projector projecting light toward a foil film, and a second projector projecting light toward the foil film. The second projector and the first projector are staggered relative to each other.

Abstract: A droplet deposition apparatus includes a standing wave generator including ultrasonic wave oscillators, a droplet supplier to supply a droplet, a workpiece retainer to retain a workpiece in a predetermined space, and a controller configured or programmed to execute causing the standing wave generator to form a standing wave in the space, causing the droplet supplier to supply the droplet to a node of the standing wave generated in the space, and bringing close to each other a predetermined position on the workpiece retained by the workpiece retainer and the node of the standing wave to which the droplet is supplied, to cause the droplet retained at the node of the standing wave to be deposited onto the workpiece.

Abstract: A non-transitory computer-readable medium includes a figure data generation program to cause a computer to execute a first process of displaying a drawing screen to make/edit an intended figure, a second process of commanding a processor to draw the intended figure on a surface of a workpiece to project a visible light onto a predetermined position on the surface, the processor including a visible-light source, the predetermined position having been designated by a user, and a third process of presenting a position corresponding to the predetermined position in the drawing screen.

Abstract: A system includes a first memory to store instrument IDs associated in a one-to-one correspondence with instruments, a second memory to store set IDs associated in a one-to-one correspondence with surgical instrument sets each including a plurality of instruments, a third memory to store work histories of the instruments each identified by a respective one of the instrument IDs, each of the work histories stored in association with the respective one of the instrument IDs and including work information about repair work, and a fourth memory to store work histories of the surgical instrument sets each identified by a respective one of the set IDs, each of the work histories stored in association with the respective one of the set IDs and including work information about repair work.

Abstract: A thermal transfer apparatus includes a controller to control a transfer tool and a pressing body conveyor. The controller controls the pressing body conveyor to press a predetermined region of a transfer object, and controls the transfer tool and the pressing body conveyor to press at least a portion of thermal transfer foil placed on the predetermined region pressed by the transfer tool and a light absorption film having a light absorption property and placed on the thermal transfer foil and to apply light to the light absorption film.

Abstract: An image forming apparatus includes an oscillator configured to oscillate a laser beam, an irradiation portion configured to radiate the laser beam oscillated by the oscillator to an outside, a light absorption unit configured to absorb the laser beam and to convert the laser beam to heat, and a control unit. The control unit is configured to control, in an irradiation state, the irradiation portion to press the irradiation portion against a workpiece with first pressing force via the light absorption unit and irradiate the workpiece with the laser beam. The control unit is configured to control, in a non-irradiation state, the radiation portion to press the irradiation portion against the workpiece with second pressing force smaller than the first pressing force via the light absorption unit, or to separate the irradiation portion from the light absorption unit so as to set the second pressing force to zero.
