  • Patent number: 11986853
    Abstract: A coating liquid containing metal as a metal-containing coating liquid is supplied to a surface to be processed of a substrate by a coating processing unit, whereby a metal-containing coating film is formed on the surface to be processed. The substrate on which the metal-containing coating film has been formed is transported to a metal removal unit by a transport mechanism. A removal liquid for dissolving the metal is supplied to a peripheral portion of the substrate by the metal removal unit such that the metal-containing coating film remains in a region except for the peripheral portion of the surface to be processed of the substrate.

  • Patent number: 11987478
    Abstract: Provided is a guide display device with which incorrect recognition of a place having small features as a ground surface having no features can be suppressed in generating and updating a three-dimensional map. A data processing unit (70): detects an edge (Eg) of a feature (E) on the basis of a result of subjecting image data captured by a camera (61) to image processing, and recognizes the feature (E) on the basis of the edge (Eg); and accumulates, from a predetermined number of frames from before the time at which the image data was captured, point group data (P) of a nearby range (Ma) of the edge (Eg) of the feature (E) that was recognized as a ground surface (F), and generates, on the basis of the accumulated point group data (P), a three-dimensional map (M) of the feature (E) the edge (Eg) of which has been recognized.

  • Patent number: 11978284
    Abstract: A preliminary image is captured that includes parts of an authentication target person. Main authentication targets are determined. The main authentication targets are those parts that each have an acceptable image-capturing state. A single image-capturing device can then be controlled to successively capture images of the main authentication parts of the authentication target person that have been determined with different settings. These images of the main authentication parts that have been captured can then be output. For instance, authentication of the target person may be performed using authentication data for each main authentication part, where such authentication is successfully when authentication for all the main authentication parts is successful.

  • Publication number: 20240103414
    Abstract: A fixing unit or device that can be used in an image forming apparatus includes a first heater element that is formed of a material that increases in electrical resistance with increases in temperature. A controller of the fixing unit is configured to vary a duty ratio of electric power applied to the first heater element during a start-up operation in which the temperature of the first heater element is raised to a target operating temperature. By varying the duty ratio during the start-up operation, changes in the resistance of the first heater element with the heating can be compensated. For example, the duty ratio can be increased during the course of the start-up to achieve the target operating temperature faster.
