Abstract: An electronic device having an auto-OFF function is disclosed in which a switch unit having an auto-OFF function and capable of being operated manually and automatically is connected to a primary circuit in a power control circuit, the switch unit S1 being normally turned auto-OFF with a signal provided from a control system circuit to cut off the supply of electric power to the primary circuit, thereby permitting a stand-by electric power to be nil, and if a trouble should occur in the control system circuit to an inoperable extent of the switch, the switch can be turned OFF manually.

Abstract: A polished glass disk medium substrate table for use as a substrate for a hard disk, a hard disk containing the substrate and methods for making the substrate. Glass forming raw materials are formed into a disk having a diameter between about 70 mm and about mm, a thickness between about 0.7 mm and about 0.9 mm, a flutter of less than 90 nm at 10,000 rpm.

Abstract: In the electric apparatus of the present invention, when the supply of electric power to a primary power supply circuit is started, a check is made to see if the apparatus has been turned ON by operation of a switch device S, by collation with the contents stored in a memory (not shown), and in accordance with the result of the collation a control system circuit makes control to continue or interrupt the supply of electric power to the primary power supply circuit. Therefore, in the case of a rise from an abnormal condition such as power failure, the supply of electric power to the primary power supply circuit can be interrupted rapidly. Thus, whether a trouble has occurred or not during power failure can be checked before resuming the operation and the occurrence of a danger can be prevented thereby.

Abstract: The present invention provides electronic equipment that can shut off and supply power to a primary power supplying circuit by automatic operations, directly shut off power to the primary power supplying circuit by easy manual operations based on the operator's will, and never fails to zero power consumption of the primary power supplying circuit during no use.

Abstract: A connecting structure in a switch device with AC inlet is disclosed wherein, when terminals of the switch device are connected together using a thin metallic connecting strip, there is no fear of an external force on the terminals causing damage to the connection between the terminals and the connecting strip and resulting in unstable contact, and which, even at different thermal expansion coefficients in a power ON condition, ensures a stably held state of the connecting strip and can afford excellent assemblability and reliability of connection.
