Abstract: A compressor includes: a compressor body that suctions and compresses a gas to be compressed; heat exchangers that circulate a cooled target inside the heat exchangers to cool the cooled target; a fan that is driven by a fan motor and that sends a cooling gas to the heat exchangers to remove heat; a temperature sensor that detects an initial cooling gas temperature that is a temperature of the cooling gas not having been subject to heat removing for the heat exchangers; and a control unit that is capable of setting an upper limit frequency that is an upper limit for controlling a rotational frequency of the fan motor. The control unit sets the upper limit frequency to a rotational frequency equal to or lower than a frequency at which current at an acceptable current level is supplied to the fan motor, at each of the initial cooling gas temperatures detected by the temperature sensor.

Abstract: In a disk device in which heads are positioned by a servo mechanism, the object of the present invention is to prevent data from being destroyed by incorrect selection of a head and to improve reliability in recording or reproducing information and to prevent format efficiency from being decreased thereby. For this object, a SAM pattern in a servo information region is changed for each head and recorded. Then, the SAM pattern is read to determine which head makes access to a disk surface and the head is compared with a head to which a direction of making access is given thereby to make an error check. Moreover, by the use of a marker pattern of rotational synchronization compensating data added to the servo information, an error check of the head making access to the disc surface is conducted.

Abstract: Settling response characteristics after change-over from a speed controller to a position controller is attained. Fluctuations in a time taken until change-over is made from the speed controller to the position controller are reduced to stabilize a moving time and to shorten an access time. To this end, a position controller generates a drive signal of a linear or primary function of time in such a manner that a position deviation signal responds to it with a ternary-order function of time which becomes zero in a desired finite settling time. Further, a feedforward signal generator is provided to reduce a follow-up error to a target position signal as an output of a target position signal generator.
