Abstract: When a cooperation source user name corresponding to identification information of a user included in a received request is included in a cooperation destination system user information, a cooperation destination system converts the identification information of the user included in the request into a user ID corresponding to the cooperation source user name in a cooperation destination system user information. The cooperation destination system processes the request based on the user ID and determines whether or not a cooperation source user name corresponding to the user ID is included in the cooperation destination system user information. In a case where the cooperation source user name corresponding to the user ID is included in the cooperation destination system user information, the cooperation destination system converts the user ID into a cooperation source user name corresponding to the user ID in the cooperation destination system user information.

Abstract: An input device includes: a rotating member that rotates about a predetermined rotation axis; and a mover that includes a protrusion protruding toward an inner peripheral surface of the rotating member and moves in a direction different from a rotation direction of the rotating member along with rotation of the rotating member. The protrusion protrudes toward an inner peripheral surface of the rotating member. The rotating member includes a first projection and a second projection that project from the inner peripheral surface toward the mover. The protrusion of the mover is inclined with respect to the predetermined rotation axis and disposed between the first projection and the second projection.

Abstract: A circuit board is in the shape of a strip and includes: in one longitudinal end portion thereof, power connection portions connected to an external power supply; in another longitudinal end portion thereof, land portions to which portions of conducting wires drawn out downwardly of a base portion are connected; and pattern portions electrically connected to the power connection portions and the land portions. The land portions include a first land portion, and a second land portion arranged adjacent to the first land portion. The pattern portions include a first pattern portion electrically connected to the first land portion, and a second pattern portion arranged adjacent to the first pattern portion, and electrically connected to the second land portion. The first pattern portion and the second land portion are arranged to overlap with each other when viewed in a widthwise direction of the circuit board.

Abstract: A fluid dynamic bearing apparatus includes a stationary body, a rotating body, and a lubricating oil arranged therebetween. One of the stationary and rotating bodies includes a shaft. Another one of the stationary and rotating bodies includes a sleeve. The sleeve includes a communicating hole arranged to pass therethrough in an axial direction or obliquely with respect to the axial direction. A groove array is defined in the stationary body or the rotating body to cause the lubricating oil to flow into the communicating hole. An opening area of an inlet of the communicating hole may be arranged to be greater than a cross-sectional area of a tubular portion of the communicating hole to make it easier for the lubricating oil to flow into the communicating hole. Further, the shape of the inlet may be modified to make a loss coefficient at the inlet lower than a loss coefficient at an outlet. This contributes to preventing a leakage of the lubricating oil.

Abstract: A fluid bearing apparatus includes a stationary member and a rotating member. A bearing surface of the stationary member and a bearing surface of the rotating member are arranged opposite to each other with a minute gap intervening therebetween. A lubricating fluid is arranged in the minute gap. At least one of the bearing surfaces includes a dynamic pressure groove, and a plurality of striations defined in a bottom portion of the dynamic pressure groove. Each of the dynamic pressure groove and the striations is arranged to extend in a direction at an angle greater than 0° to a circumferential direction. An angle defined between each striation and the circumferential direction is equal to or smaller than an angle defined between the dynamic pressure groove and the circumferential direction. Thus, an improvement in a force of dynamic pressure at the dynamic pressure groove is achieved.

Abstract: A rotating apparatus includes a hub, a shaft housing portion having a center through-hole, a base plate, and a shaft with a cylindrical section housed in the through-hole. At a joint between the shaft housing portion and the hub is formed a bonding region for bonding the shaft housing portion and the hub by a hardening resin, and a narrow-gap region more toward the base plate than the bonding region. A gap between the shaft housing portion and the hub in the narrow-gap region is narrower than a gap between the shaft housing portion and the hub in the bonding region. The hub includes a fourth circumferential recessed portion recessed in the axial direction and a lower circumferential raised portion projecting in the axial direction on a radially inner side of the fourth circumferential recessed portion. The narrow-gap region is located inside the lower circumferential raised portion.
