Abstract: A bias circuit able to keep a bias current constant even if a threshold voltage of a transistor changes, provided with a resistance element connected between a bias voltage supply line and a gate and changing in resistance value linked with the threshold value of the transistor. Even if the threshold value of the transistor changes, the resistance value changes in response to the change of the threshold value. When the threshold voltage increases, the resistance value decreases and the bias voltage is adjusted by resistance division to increase. When the threshold voltage decreases, the resistance value increases and the bias voltage is adjusted by resistance division to decrease. The transistor is a junction type transistor having a first conductivity type channel and a second conductivity type gate. The resistance element is formed in the second conductivity type semiconductor region.

Abstract: An ID (MID) is attached to each individual optical disk, and content is encrypted with a Content-Key and registered. In addition, a system server device maintains a Client ID of a client terminal device, HDD-ID of a hard disk drive (HDD), and MC-ID of a memory card respectively held as user entry information. When the user wants to copy the content, together with the optical disk MID, the MC-ID is sent to the system server side. The system server device identifies the user by referencing the MC-ID in the user entry information, and returns a Content-Key, which is used when encoding content. On the user side, content stored in the optical disk is decrypted using the returned Content-Key and copied to the HDD. Accordingly, copying of content is allowed only for an authorized user who is the lawful owner of the storage media.

Abstract: A duty ratio for controlling an engagement force of a friction engagement device on the side of upshift engagement is corrected by an amount corresponding to an intermediate correction control value in the course of the shift. In addition, on a prerequisite condition that learning correction of a constant standby pressure control value at the start of the shift is converged, learning correction is performed for the intermediate correction control value according to a gradient of a turbine speed. Thus, a shift shock is prevented from occurring due to abrupt engagement of the friction engagement device and the like at the completion of the shift.
