Abstract: An analog meter reading system is applied to an analog meter provided with a scale and a pointer and reads a measured value of the analog meter. The analog meter reading system includes: a unique information acquisition unit that acquires unique information of the analog meter; an image acquisition unit that acquires an image of the analog meter for reading the measured value; a detection unit that detects a reference point on the scale and a pointer from the image; a rotation angle calculation unit that calculates a rotation angle of the pointer until a state in which the pointer points to the reference point changes to a state in which the pointer points to the measuring point based on the reference point and the pointer that are detected; and a measured value conversion unit that converts the rotation angle into the measured value using the unique information.

Abstract: A premixed combustion burner includes: a mixing part including a first peripheral wall having a center burner axis, a mixing region for mixing fuel and air in the first peripheral wall, and air supply ports arranged circumferentially and open in the first peripheral wall; a nozzle on the mixing part side, a second peripheral wall having a center burner axis, a premixed gas passage continuous to the second peripheral wall mixing region, and a cooling passage in the second peripheral wall; and a header part proximal to the mixing part, and a first header chamber with a fuel supply port, second header chamber, and fuel ejection port for communication between the second header chamber and mixing region. The first peripheral wall has an outward path connecting the first header chamber and a cooling passage inlet, and a return path connecting cooling passage outlet and the second header chamber.

Abstract: Selecting one conveyance mode from a plurality of conveyance modes includes a first selection process of selecting the one conveyance mode based on a detection temperature of a temperature sensor from a first time point at which rotation of a fixing rotator is started to a second time point at which a particular period elapses from the first time point. The first selection process includes: determining whether an initial temperature is higher than or equal to a first temperature, the initial temperature being a detection temperature of the temperature sensor when a print instruction is received; in response to determining that the initial temperature is lower than the first temperature, setting the particular period to a first period; and in response to determining that the initial temperature is higher than or equal to the first temperature, setting the particular period to a second period longer than the first period.

Abstract: An anti-reflective structural body is constituted of an integrally molded article and includes an anti-reflective structure formed on a base surface that constitutes an outer surface of the molded article, and the anti-reflective structure includes a plurality of recesses, each being formed to be recessed from the base surface independently of mutually adjacent recesses and having an inclined surface, which is inclined with respect to the base surface and forms at least one punctiform or linear apex portion at a bottom portion.

Abstract: A fusing apparatus, including a base member, a sheet member, a fixing portion, and an endless member, is provided. The sheet member includes a contact portion to contact an inner peripheral surface of the endless member, a first portion having a first hole, and a second portion to be fixed to the base member. The base member includes a first face to support the contact portion, a second face, and an inner face recessed from the second face to form a recessed portion. The fixing portion includes a first engagement portion protruding from the inner face of the recessed portion to be engageable with the first hole, and a holder provided at the first engagement portion to hold a peripheral portion around the first hole in the first portion of the sheet member at a position between the inner face of the recessed portion and the holder.
