Abstract: A method for managing electronic components includes a manufacturer-side process including preparing bulk cases provided with RFID tags storing unique IDs and including electronic components stored therein, storing manufacturer-side information in association with the unique IDs in a manufacturer-side-information storage area on a cloud, and shipping the electronic components on a per-bulk case basis, receiving the shipped bulk cases, reading the unique IDs stored in the RFID tags, and obtaining, based on the read unique IDs, the manufacturer-side information stored in the manufacturer-side-information storage area in the cloud.

Abstract: A door mirror base including a base main unit for holding a vehicular door minor and a gasket disposed between the base main unit and a vehicle body. The gasket includes a hook protruding toward a vehicle body side and to be hooked onto the vehicle body. The base main unit includes a reinforcing pin passed through the gasket and protruding toward the vehicle body side of the gasket along the hook. The reinforcing pin includes a locking portion exposed on the vehicle body side of the gasket and caught by a surface of the gasket on the vehicle body side. By visually recognizing the locking portion from the vehicle body side of the gasket, it can be confirmed that the reinforcing pin is sufficiently passed through the gasket. Additionally, the locking portion makes it difficult for the reinforcing pin to be removed from the gasket.

Abstract: A retard roller of non-ground surface type which is virtually free from adhesion of paper dust thereby to have an excellent friction coefficient sustain ability, and which is free from creaky noises at a relatively low sheet feeding speed; a retard roller of non-ground surface type having little variation in outer diameter; and a sheet feeder employing such a retard roller. The retard roller comprises a roller body and a shaft extending axially therethrough, the roller body having a textured roller surface comprising a multiplicity of island portions (10) and a sea portion (11) recessed from the island portions, the island portions and the sea portion each having a multiplicity of fine projections (12). The ratio S1/S2 of the total area S1 of the island portions to the area S2 of the sea portion preferably is 0.25 to 0.55. The fine projections preferably each have a height of 3 to 25 &mgr;m.
