Abstract: Communication with a user is more naturally and effectively realized. An information processing apparatus includes an autonomous mobile body (10) that travels while maintaining an inverted state, and an operation control unit (230) that controls an operation of the autonomous mobile body. The autonomous mobile body includes a main body (10), two wheels (570) mounted on the main body, and a drive mechanism (565) that drives the two wheels. The operation control unit controls the drive mechanism to maintain the inverted state of the autonomous mobile body by the two wheels in a first state, and make the autonomous mobile body come to rest by the two wheels and a bottom of the main body when the autonomous mobile body transfers from the first state to a second state.

Abstract: A light quantity adjuster includes: a blade member forming an aperture; a stepping motor that moves the blade member to open/close the aperture; and a control section that controls driving of the stepping motor, and increases a rotational speed of the stepping motor after a resistance acting on the stepping motor changes from static friction to dynamical friction in case of closing the aperture.

Abstract: A flexible printed circuit board using a lead-free solder is to be fixed within a disk enclosure while ensuring a high rigidity. In one embodiment, a rotating disk storage device comprises a flexible printed circuit board (FPC), wherein there is formed a wiring pattern including a signal line for the transmission of a signal of data read by a head in an actuator head suspension assembly (AHSA) and wherein one side end portion is fixed to a base and an opposite side end portion is fixed to the AHSA. A first metallic plate and a second metallic plate are both fixed to one side end portion of the FPC. A connector is disposed in an area where the first metallic plate in the FPC is provided, and connected to the wiring pattern. A shock sensor is disposed in an area where the second metallic plate in the FPC is provided, and connected to the wiring pattern.
