摘要： A hard disk drive is disclosed in which the disk has tracks each divided into alternating data sectors and servo sectors, with the control data such as track addresses on the servo sectors being normally recorded more stably than the main data on the data sectors. In order to obtain read pulses representative of the peaks of the output waveform of a transducer, this waveform is directed on one hand into a differentiator circuit and thence into a wave shaping circuit for the provision of data pulses which rise and decay in synchronism with the peaks of the transducer output waveform. On the other hand, the transducer output waveform is sent into a gate pulse circuit, in which the waveform is compared with a reference signal in order to provide gate or window pulses. A logic circuit is provided for ascertaining whether the data pulses rise and decay within the durations of the gate pulses and, if they do, for producing read pulses indicative of the rises and decays of the data pulses. The duration of the gate pulses is made shorter for recovery of the control data than for main data recovery, with a view to more precise detection of the peaks of the transducer output waveform representative of the control data.

摘要： An electrostatically atomizing device includes an emitter electrode, an opposed electrode disposed in an opposed relation to the emitter electrode, liquid supply means for supplying a liquid to the emitter electrode, and high voltage generating means for applying a high voltage across the emitter electrode and the opposed electrode. The liquid supplied onto the emitter electrode is electrostatically charged through application of the high voltage, as a result of which charged minute liquid particles are discharged from a discharge end of the emitter electrode. The device includes detecting means for detecting a discharge condition developed between the emitter electrode and the opposed electrode, and a controller for controlling the high voltage generating means to regulate its voltage output so as to maintain a predetermined discharge condition, based on detection results by the detecting means. Charged minute particles can be continuously generated in an amount corresponding to the predetermined discharge condition, by adjusting the discharge voltage that is applied to the emitter electrode.

摘要： An emitter electrode is cooled by a cooler to generate condensed water which is charged by a high voltage applied between the emitter electrode and an opposed electrode and is discharged as a mist of charged minute water particles. A controller is provided to vary a temperature drop to a predetermined minimum temperature in dependence of an environmental temperature detected by a temperature sensor. The temperature drop is made variable in proportion to the environmental temperature. Accordingly, a sufficient amount of water can be condensed on the emitter electrode simply by controlling the cooling of the emitter electrode without relying upon an environmental humidity.

摘要： A disklike record medium such as a magnetic data storage disk, and a closed-loop servo control system for positioning a transducer such as a magnetic read/write head on any of a multiplicity of concentric tracks on the record medium. The tracks on the record medium are divided into a plurality of groups, and each track of each group has a different code character prerecorded thereon as in the form of discretely magnetized regions. All the groups of tracks have the same set of code characters assigned thereto for the simplicity of the code characters. Read by the transducer, the code characters enable the control system to individually identify all the tracks of all the groups. In response to an externally supplied track command indicative of a destination track on which the transducer is to be positioned, and to internally supplied track code data, the control system causes translation of the transducer from a departure track to the destination track during track seek operations.

摘要： An air conditioning system with an electrostatically atomizing function includes an electrostatically atomizing unit and a ventilation duct which flows conditioned air. The electrostatically atomizing unit generates a mist of charged minute water particles. The electrostatically atomizing unit is provided with a discharge port which locates adjacent to an air outlet of the ventilation duct. The mist of the charged minute water particles flows into an airflow which is sent from the ventilation duct. The mist of the charged minute water particles effectively spreads to the space by the air flow without dissipating inside the ventilation duct.

摘要： An electrostatically atomizing device includes a housing and an electrostatically atomizing unit disposed within the housing. The atomizing unit includes an emitter electrode and an heat exchanger. The heat exchanger cools the emitter electrode to develop condensed water. A high voltage is applied to the emitter electrode in order to electrostatically atomizing the condensed water and generate a mist of charged minute water particles. The housing accommodates a fan generating an air flow accelerating a heat radiation of the heat exchanger, and a high voltage source generating the high voltage applied to the emitter electrode. The heat exchanger has its heat radiator section exposed to a flow passage of the air flow. The atomizing unit is formed with an air inlet for introducing the air flow which carries the mist of the charged minute water particles and release the mist. The atomizing unit and the high voltage source are arranged on opposite sides of the flow passage. A first air intake port for feeding the forced air flow from the fan and a second air intake port for feeding the air flow into the high voltage source are positioned upstream of a second air intake port which introduce the forced air flow into the flow passage.

摘要： An electrostatic atomizer comprising a discharge electrode, a counter electrode, a cooling source, a high voltage power supply and a voltage detector. The cooling source cools the discharge electrode to form thereon dew as water. The power supply applies high voltage for discharge across the electrodes. The detector detects voltage between the electrodes. The power supply includes a control device and a voltage stabilizing device that are opposite to each other in temperature characteristic. The control device operates to pick up the voltage detected with the detector via the voltage stabilizing device, and to adjust the high voltage applied across the electrodes through feedback control so that the voltage corresponds to specified discharge voltage.

The device further includes a controller for discharging the charged minute water particles in a stable manner. The controller monitors a discharge current flowing between the two electrodes to control the cooling means for keeping the discharge current at a predetermined level, thereby regulating the atomizing amount of the charged minute particles from the emitter electrode.

摘要： In a data storage and retrieval system employing a magnetic disk as the storage medium, a monophase encoder is coupled, typically, to an electric seek motor for optoelectronically producing an output representative of the position of a data transducer with respect to a multiplicity of concentric data tracks on the disk. Electrically connected to the monophase encoder is a triple detector circuit for deriving from the encoder output a transducer position signal representative of the transducer position on the disk, an actual transducer speed signal representative of the transducer speed relative to the disk, and a track boundary signal representative of boundaries between the data tracks on the disk. The transducer position signal and actual transducer speed signal are both fed to a seek motor control circuit, whereas the track boundary signal is fed to a controller microprocessor, which then delivers to the seek motor control circuit a requested transducer speed signal at which the transducer is to be moved across the data tracks during operation in a seek mode. In response to the incoming signals the control circuit controls the seek motor for transporting the transducer to a desired track at a desired speed and for positioning the transducer in centerline alignment with the track.
