Abstract: An optical deflector includes: a reflecting section driven to rotate or oscillate around a drive axis; and a diffraction section configured to diffract light reflected by the reflecting section. The reflecting section is driven to change a first incident angle of light, around the drive axis, incident on the diffraction section from the reflecting section. The diffraction section changes a first emission angle of light emitted from the diffraction section, around a first axis perpendicular to the drive axis and a predetermined direction defined to extend from the reflecting section toward the diffraction section perpendicularly to the drive axis. The diffraction section is driven about the drive axis together with the reflecting section to maintain a second incident angle of light incident on the diffraction section from the reflecting section, around the first axis.

Abstract: A trained model generating method includes: acquiring a first model obtained by performing training processing for an estimation target in a first environment by using first image data representing the estimation target in the first environment as learning data; acquiring second image data representing the estimation target in a second environment in which estimation is to be performed; generating a second model based on the first model by using the second image data as learning data; and outputting a trained model based on the second model. The second image data includes an image in which an appearance of the estimation target in the second environment is assumed based on user environment information about the second environment.

Abstract: A control apparatus (20) includes a control device (21) and the control device (21) includes: a detector (214) that detects an entering person (P) entering a range (E1) of motion of an arm (11); and a limiter (215) that, upon detection of the entering person (P) entering the range (E1) of motion by the detector (214), sets a behavior prohibition range (E2) of the arm (11) where the arm (11) is kept from coming into contact with the entering person (P), thus limiting a behavior of the arm.

Abstract: A robotic device performs work defined by a series of unit jobs. The robotic device includes a first notice section and a controller. The controller includes a first calculation section that calculates end time of the work based on time required for the work. The controller controls the first notice section so that the first notice section issues notice of ending the work before the end time. The controller further includes a first determination section that determines, based on the end time, time to issue the notice. The time to issue the notice is time before the end time.

Abstract: An image forming apparatus includes a hand detection sensor that detects a hand within a predetermined range from a grasping part of a sheet feeding cassette, a locking mechanism capable of locking the sheet feeding cassette in a closed state with respect to the image forming apparatus body, and an operation control unit that operates the locking mechanism to lock the sheet feeding cassette when the hand is detected by the hand detection sensor during the execution of a printing process in an image forming apparatus body, interrupts the printing process after the locking, and releases the locking by the locking mechanism after the interruption.

Abstract: A first agent for oxidative hair dye of the present disclosure includes: an (A) component, which is at least one selected from the group consisting of resorcin, derivatives thereof, and salts thereof, in a content not exceeding 0.15% by mass; a (B) component, which is a coupler such as m-aminophenol, a (C) component, which is a dye intermediate such as p-phenylenediamine in a content between 0.01% by mass and 0.45% by mass; and a (D) component, which is an alkanolamine.

Abstract: This image forming apparatus includes an image carrier, a charging member, a capacitor, a voltage control portion, and a current conduction control portion. The charging member is configured to charge the image carrier. The capacitor is connected on a current conduction path connecting the charging member and a ground. The voltage control portion is configured to control whether or not to apply DC voltage to the charging member. The current conduction control portion is configured to make the current conduction path conductive after DC voltage is applied by the voltage control portion, and to disconnect the current conduction path before application of DC voltage by the voltage control portion is stopped.
