Abstract: A target PES value input from a controller and a value from a PES value calculator which corresponds to the displacement of a magnetic head are synthesized. A coefficient applicator applies a predetermined coefficient K1 to the above deviation (multiplication), and a variable coefficient applicator applies a coefficient Ka to the resulting value. The coefficient Ka is varied and set in the variable coefficient applicator in accordance with a value input from a table. The correspondence between the target PES value and the coefficient Ka used as a feedback coefficient for the PES value is stored in the table in advance so that the coefficient Ka is small when the PES value varies sharply and so that the coefficient Ka is large when the PES value is small. The variable coefficient applicator outputs, to a driver, a value to which the coefficient Ka has been applied in accordance with the value from the table.

Abstract: PROBLEM TO BE SOLVED: To provide a detection circuit for microphone plug and line plug that can use a microphone jack and a line jack in common, a common use circuit for the jack, an adaptor using the jack in common, and a notebook PC provided with the common use jack. SOLUTION: While a plug of an external device to be connected is plugged into a jack and connected, a difference of impedance between a ring pin and a tip pin of the jack is obtained, whether the jack to which the external device is connected is a microphone or a line jack is detected on the basis of the difference of impedance to be obtained. In the case of the microphone jack, it is controlled so that a DC bias is applied to the ring pin or the tip pin of the jack, and in the case of the line jack, no DC bias is given to the ring pin and the tip pin of the jack, or in the case of a device using the line jack, the device is connected to the common use jack via an adaptor with a prescribed DC cut function.

Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of the system by performing no unnecessary CPU throttling by the power management device which performs CPU throttling. SOLUTION: The power management device 10 comprises an event detection part 12 which detects an event in the system, an activity detection part 14 which decides whether the system is in an idle or active state by checking activities in the system, and a clock control part 14 which performs CPU clock control. The clock control part 16 stops the CPU throttling when the system is in the idle state and performs the throttling only when the system is in a busy state, so that no unnecessary CPU throttling is performed.

Abstract: PROBLEM TO BE SOLVED: To provide a data transferring device, a computer device, a device, and a docking station capable of stabilizing the signal waveform at the time of transferring data. SOLUTION: In this PC system, at the time of transferring data between a host part 10 and an HDD device 40 or a CD-ROM drive device 30 through an IDE bus 20, a signal is fed back from the reception side of the data through a feedback circuit 50 to the transmission side of the data so that the through- rate of a signal to be transmitted at the transmission side can be changed based on this. Moreover, when the CD-ROM drive device 30 or the HDD device 40 is attached or detached while the power source of the PC system is applied, calibration is performed by a calibration performing part 83 so that the through- rate of a signal to be transmitted at the transmission side can be changed.

Abstract: PROBLEM TO BE SOLVED: To improve an S/N ratio in a mute state by informing an information processor of the fact that it is in the mute state when the read out data are not the audio data. SOLUTION: A CPU: 220 discriminates whether a signal read by an optical head 211 is either of the audio data or the computer data. When the read data are the audio data, the data are sent out through a DAC: 230, and the CPU: 220 informs the information processor of the mute signal of a low level. Further, when the read data are the computer data, the data are sent out to the information processor through a decoder circuit 240A and an interface circuit 240B, and the CPU: 220 outputs the mute signal of a high level to the information processor. High potential is applied to the gate of an FET switch 270, and an output of a driver 232 is lowered to a grounded level, and the occurrence of a noise is prevented.

Abstract: PURPOSE: To contact a stable follow of the head in any area in the tracks. CONSTITUTION: A target PES(phase error signal) value input from a controller body 61 and a value corresponding to the displacement of the current magnetic head 58A from the PES value calculating means 56 are combined with a combining means 62, the predetermined coefficient K1 is given (multiplied) to this deviation by means of a coefficient giving means and a variable coefficient Ka is given by means of a variable coefficient giving means 47. The coefficient Ka is variably set to the variable coefficient giving means 47 depending on the value input from a table 48. The table 48 previously stores the corresponding relationship between the target PES value and the coefficient Ka as the feedback constant to the relevant PES value so that when change of PES value is large, the coefficient Ka becomes small and when PES value is small, the coefficient Ka becomes large. The variable coefficient giving means 47 outputs the value given the coefficient Ka depending on the value from the table 48 to a driver 46.
