摘要： A magnetic disk system which records and reproduces data on a magnetic disk at different data transfer rates depending on a track position on the disk includes a transversal waveform equalizing circuit which implements an optimal waveform shaping for a readout waveform. The waveform equalizing circuit consists of a register, a frequency synthesizer, a PLL, and a transversal circuit. The transversal circuit consists of variable delay circuits, variable gain amplifiers, and an adder. The frequency synthesizer produces a write clock signal having a frequency which corresponds to a value stored in the register which depends on the data transfer rate, and the PLL responds to the write clock signal to produce a control signal by which the delay time of the transversal circuit is controlled. Consequently, the delay characteristic is not affected by disparity of circuit components of the transversal circuit, and the write clock frequency and the delay time of the transversal circuit can be set to intended values by merely changing the value stored in the register in response to a variation of the data transfer rate.

摘要： In controlled cooling operation, data on the controlled cooling operation characteristics is read out from a memory and compared with a drop degree of an inside temperature actually measured by an inside temperature sensor 46, and a cooling device is operated so that the inside temperature drops following a temperature curve stored in advance. A state where the inside temperature is higher than the set temperature by 7 K or more lasts for 15 minutes, for example, the cooling capacity by the cooling device is increased than the cooling capacity based on control of a controlled operation controller so that even if a door 17 is frequently opened/closed and the inside temperature tends to gradually rise, it can be detected at an early stage and kept close to the set temperature.

摘要： Deviation calculating means 42 calculates a deviation between an internal temperature detected by a temperature sensor 35 and a target temperature provided from target temperature setting means 41 for each predetermined time period. The deviation is integrated by deviation integrating means 46. When the integrated value exceeds a predetermined reference value, a rotational speed of an inverter motor that drives a compressor is increased. Therefore, for example, even if an internal temperature temporarily rises because a door is opened temporarily and outside air flows into a storage compartment, because there is no sudden change in the integrated value of the temperature deviation and the rotational speed of the compressor does not react in an oversensitive manner and rapidly increase. Consequently the control is stable. Thus, an unnecessarily oversensitive response to a sudden change in an internal temperature can be prevented, enabling operation at a higher efficiency.
