An electronic circuit unit contains electrodes to which bumps of a semiconductor chip are adhered. The electrodes are arranged on an upper surface of a circuit board. Land units to which chip parts is soldered are arranged on a rear surface of the circuit board. such that an insulating plate which is on the rear surface of the circuit board is supported by a supporting jig during a mounting process of the semiconductor chip, and the circuit board is not tilted. Therefore, an electronic circuit unit ensuring that the semiconductor chip is mounted with a reliable mounting capability can be obtained.

To provide an image reproducing apparatus which requires a small amount of memory capacity in reverse reproduction. The apparatus has an analyzing unit for acquiring interrelation between a plurality of items of reference image data to be referred to during decode processing from control data with a stream of encoded data, a buffer unit, and a decoding unit. An accumulation control unit uses the interrelation information obtained in the analyzing unit to extract the plurality of items of reference image data from the stream and to temporarily accumulate the same in the buffer unit. A decode control unit sequentially outputs reproduced image data decoded in the decoding unit in reverse time series as a reverse reproduction.

There is provided a cathode ray tube capable of displaying high quality images by suppressing eddy current from occurring and by realizing the velocity modulation. A cylindrical focusing electrode is divided into first cylindrical focusing electrode 4B and second cylindrical focusing electrode 4T and the gap between the both electrodes formed and divided by optimizing the length of the second cylindrical focusing electrode 4T in the tube axial direction is enlarged substantially to increase the infiltration of the velocity modulating magnetic field to the non-electric space of the focusing electrode 4. An electrode 4a having the equal potential with the focusing electrode 4 is disposed at the gap to suppress eddy current from being generated.
摘要:
This invention relates to a motor velocity control method and storage device for performing loading/unloading control of a head that reads from a storage medium in order to move it away from the storage medium. In order to detect accurate velocity from the counter electromotive voltage of the motor for performing loading/unloading control, the storage device comprises a storage medium 6, head 4, actuator 3, control circuit 19 and ramp 11. Velocity control is performed by using the velocity detected from the counter electromotive voltage of the actuator 3 in the unloading/loading control of moving the head 4 away from the storage medium 6. Moreover, the transient response voltage of the actuator is calculated and the detected voltage is corrected. Furthermore, the velocity offset coefficient for converting the counter electromotive voltage to velocity is calibrated. Also, the velocity correction coefficient for converting the counter electromotive voltage to velocity is calibrated. This makes it possible to obtain accurate velocity from the counter electromotive voltage.
