  • Patent number: 9773515
    Abstract: An HGA loader provides HGAs, in succession, to a multiple workstation head tester. An HGAs carrier station receives HGAs to be tested. An alignment station on the base includes an alignment surface which selectively rotates about an alignment axis. A camera generates images of an HGA on the alignment surface, which is rotated so that the HGA has a desired spatial orientation which is maintained as the HGA is transferred to an HGA testing workstation. A received, oriented HGA is positioned to enable read/write test operations on a disk rotating on an adjacent spinstand. To effect the successive position operations, a transporter includes a track overlying the workstations, and a carriage movable along the track, to pass from workstation to workstations. The loader is automatically operative under the control of a controller.

  • Patent number: 9766279
    Abstract: Provided is an electronic apparatus that can prevent erroneous detection of a sensor output due to an AC line noise. A power supply circuit includes a noise filter, input rectifying smoothing circuit, converter circuit, and output smoothing circuit. The input rectifying smoothing circuit rectifies an input AC voltage passed through the noise filter to a pulsating flow and then smooth it. The converter circuit converts a DC voltage rectified and smoothed into a desired output voltage. The output smoothing circuit smoothes the convert output voltage to supply it to a control part. The noise determination part detects a noise that could not have been removed by the noise filter, as an AC line noise. The control part invalidates a detection signal outputted from the sensor for a previously set invalid period from the moment the AC line noise has been detected.

  • Patent number: 9689660
    Abstract: An object of this invention is to sense a transient displacement of the blade position to thereby detect abnormalities early. The invention includes: one or more first sensors mounted so as to be removable from an outer surface of a casing opposed to blade tips; a second sensor for acquiring a signal from a fixed point on a rotor shaft of the blades; a section configured to extract data groups from an output signal of the first sensor on the basis of information acquired by the second sensor; a section configured to average the data groups; a section configured to determine thresholds from averaged data obtained under a healthy condition; and an assessing section configured to compare magnitude of the thresholds and sensor signals obtained during blade status monitoring. Since a transient displacement of blade position can be sensed, abnormalities can be detected early in this invention. This early detection, in turn, enables a rotation to be stopped during an initial phase of blade damage.

  • Patent number: 9685874
    Abstract: A circuit and a method for evaluating a load condition in a flyback converter are disclosed. A first current source is used for providing a preset current ISUM equal to a sum of the off current value IOFF and the blanking current value ILEB to charge a first capacitor, and a second current source is used for providing a reference current IREF to charge a second capacitor. A comparator receives a voltage applied on the first capacitor at its positive input end and a voltage applied on the second capacitor at its negative input end. The output current transmitted to the load by the flyback converter is varied to the change of the preset current ISUM, as such the load condition is detected by the comparison result generated by the comparator.
