Abstract: An air-conditioner controller that controls an operation of an air conditioner includes: a storage unit that stores, for each user, voiceprint data that is data indicating a voiceprint of a user and personal data that is data indicating a feature of the user; and a control unit that compares voice data that is data of a user's voice detected in an air-conditioning area that is an area subject to air-conditioning control of the air conditioner with the voiceprint data, and, when there is voiceprint data similar to the voice data, presents a question based on the personal data to identify a user in the air-conditioning area on the basis of an answer acquired from the user in the air-conditioning area.

Abstract: An endoscope is provided that obtains a favorable field of view. The endoscope includes: an illumination optical system that has an illumination window protruding from an end surface of an insertion unit; a cylindrical body that protrudes from the end surface; and an observation window that is arranged inside the cylindrical body and protrudes from the end surface, in which the illumination window and the observation window satisfy Formulas (1) and (2), and an intersection between a straight line, which connects an edge of a light incident surface of the observation window and an edge of an end surface of the cylindrical body, and an optical axis of the illumination optical system is located to be closer to the insertion unit than the end surface of the insertion unit. C?D??(1) E?D??(2).

Abstract: An endoscope is provided that obtains a favorable field of view. The endoscope includes: an illumination window that protrudes from an end surface of an insertion unit; an observation window that protrudes from the end surface; and an outlet that protrudes from the end surface and emits water or air to the observation window, and satisfies Formulas (1) and (2). C?D . . . (1) 2N?C . . . (2) C is a maximum protruding amount of the observation window the end surface of the insertion unit. D is a maximum protruding amount of the illumination window from the end surface of the insertion unit. N is a maximum protruding amount of an inner surface of the outlet from the end surface of the insertion unit.

Abstract: {circle around (1)} A spindle motor includes a fixing portion defined by a bearing portion, a holder portion, a gap between the bearing portion and the holder portion, and an adhesive arranged in the gap. {circle around (2)} The fixing portion includes first and second protruding surfaces arranged to protrude radially from a first and a second one, respectively, of an outside surface of the bearing portion and an inside surface of the holder portion; and first and second boundary surfaces arranged to join the first and second surfaces, respectively, to the first and second protruding surfaces, respectively. {circle around (3)} At least a portion of the first boundary surface is arranged above the second boundary surface. {circle around (4)} The first and second protruding surfaces are arranged radially opposite to the second and first surfaces, respectively, with a first and a second gap, respectively, intervening therebetween.

Abstract: A spindle motor includes a recording disk and a clamper. A cylindrical portion includes a first screw portion positioned in an outer circumferential portion of the cylindrical portion. The clamper includes an annular raised portion configured to be fitted in a through hole of the recording disk. An inner circumferential portion of the clamper includes a second screw portion configured to be screwed to the first screw portion. At least a portion of the second screw portion is positioned in an inner circumferential portion of the annular raised portion. Each of the first screw portion and the second screw portion includes at least one of a screw groove and a screw thread. An axial position of at least a portion of the second screw portion overlaps with an axial position of the recording disk.
