Abstract: A closure is inserted into a casing for closing one end of the casing. A projecting portion projecting from an inner peripheral surface of the casing is formed at a position slightly away from the one end of the casing. The projecting portion is formed as a projecting rib around a periphery of the casing. After the closure is inserted into the casing, the closure engages the projecting portion. An edge of the casing is bent toward the inside of the casing, so that the closure is sandwiched and fixed by the projecting portion and the edge. The closure may be subjected to a coining process to closely fix the closure to the casing.

Abstract: A disk recording/reproducing device includes a power transmitting mechanism which transmits movement of a pickup while engaging with the pickup, and a disk retaining mechanism which, in response to the movement of the pickup transmitted by the power transmitting mechanism, retains a disk on a turntable or releases retention of the disk. Radially inward movement of the pickup causes the disk retaining mechanism to retain the disk on the turntable, while radially outward movement of the pickup causes the disk retaining mechanism to release retention of the disk. For accomplishing the release of the retention of the disk upon the radially outward movement of the pickup, an operation switching mechanism is provided for changing a position of the power transmitting mechanism to cause the power transmitting mechanism to engage with the pickup upon the radially outward movement of the pickup.

Abstract: An industrial robot includes a movable arm and an electric motor driving the arm. A current flowing through the motor is controlled so that the arm is moved into predetermined positions and is balanced in the predetermined positions sequentially. A device memorizes values of the motor current at which the arm is balanced in the respective predetermined positions. A target value of the motor current is calculated on the basis of the memorized motor current values. The target motor current value allows the arm to be balanced in a given position.
