An object of the present invention is to obtain a vibration damper capable of instantly changing or rapidly increasing the spring constant of the vibration damper, with improving sealing properties. An intermediate cylinder 16 is fittingly engaged with the inner peripheral surface of an outer cylindrical metal member 12. The intermediate cylinder 16 and a mounting metal member 22 are elastically connected by a rubber elastic body 24. A circular tube portion 36A of a yoke forming member 36 is provided at a position on the inner peripheral side of the intermediate cylinder 16. A coil 46 is to disposed between the intermediate cylinder 16 and the yoke forming member 36. A pressure receiving liquid chamber 40 in which a portion of an inner wall thereof is formed of the rubber elastic body 24 communicates via an orifice 44 with a secondary liquid chamber 42 which is elastically deformable due to presence of a diaphragm 38, such that a magnetism responsive fluid can flow in either direction between the pressure receiving liquid chamber and the second liquid chamber. A yoke portion 36C is provided on the inner peripheral side of the circular tube portion 36A such that the yoke portion 36C is situated along magnetic path which is generated upon electrical activation of the coil 46.

A current drive circuit supplies a driving current to a pixel portion included in a current-driven display panel. A driving current generator includes an output terminal for supplying the driving current. A protective transistor has a drain connected to the pixel portion, a source connected to the output terminal, and a gate to which a first bias voltage is supplied. The first bias voltage has a voltage level lower than or equal to a voltage level obtained by adding the threshold voltage of the protective transistor to the breakdown voltage of the driving current generator.

An information processing apparatus includes a port that connects a peripheral apparatus to the information processing apparatus through a USB, a first switch that interrupts supply of a power to the peripheral apparatus through the port under an OS control, a second switch that interrupts the supply of the power to the peripheral apparatus when the first switch operates to supply the power thereto, and a control unit that monitors whether a failure occurs to a connection between the information processing apparatus and the peripheral apparatus through the port and that controls an operation of the second switch based on a monitoring result independently of the OS control. The control unit switches the second switch so as to reset the connection when detecting that the failure occurs to the connection.
