20080198497 | HARD DISK DRIVE APPARATUS, METHOD TO CONTROL FLYING HEIGHT OF MAGNETIC HEAD THEREOF, AND RECORDING MEDIA FOR COMPUTER PROGRAM THEREFOR - A method of controlling a flying height of a magnetic head of a hard disk drive apparatus includes producing a reference FOD (flying on demand) voltage profile defining a relationship between the flying height of the magnetic head and an FOD voltage at a measured temperature, wherein an end of the magnetic head thermally expands and protrudes when the FOD voltage is applied to a heater included in the magnetic head and setting the reference FOD voltage profile that is corrected using a reference maximum flying height of the magnetic head that is preset at room temperature, as an applied FOD voltage profile to control the flying height of the magnetic head. | 08-21-2008 |
20080266704 | Hard disk drive, method of controlling flying height of magnetic head thereof, and recording medium containing computer program thereon - A method of controlling a flying height of a magnetic head of a hard disk drive includes calculating a corrected flying on demand (FOD) voltage to correct a difference between a measured flying height measured by applying a burn-in FOD voltage corresponding to a target flying height and a burn-in flying height in a reference FOD voltage profile corresponding to the burn-in FOD voltage, using the reference FOD voltage profile, in the reference FOD voltage profile that is a profile of a second signal for calculating the flying height of the magnetic head with respect to a first signal for calculating an FOD voltage that allows an end of the magnetic head to thermally expand and protrude when applied to a heater included in the magnetic head, and applying an applied FOD voltage obtained by applying the corrected FOD voltage, to the burn-in FOD voltage, to control the flying height of the magnetic head. Thus, the reliability in the read/write operation can be improved and performance of the hard disk drive can be improved. | 10-30-2008 |
20100141679 | System to Compose Pictorial/Video Image Contents With a Face Image Designated by the User - A system for composing pictorial/video image contents where the Face Image which the User designates (FIU) is reflected is disclosed. The system provides a series of pictorial/video image composing pipe line for changing the face of a specific source character that appears in pictorial/video image contents to a FIU pattern and guides a video related company (for example, a producer, a distributor, a sales agency (provider), etc.) to establish a base infra for producing/manufacturing/marketing a video on demand (VOD) content that reflects individual desire of a user so that it can satisfy user needs in changing the face image of a specific character appearing in pictorial/video image contents into the face image of a favorite person (or the user designates, for example, his/her own face image, the face image of his/her acquaintance, the face image of a specific celebrity, the face image of a specific politician, and so on). | 06-10-2010 |
20100296191 | HARD DISK DRIVE - A hard disk drive effectively removes internal humidity therefrom and thus improves the reliance and performance of the hard disk drive in high and increased humidity environments. | 11-25-2010 |
20110172621 | CLEANABLE AND REUSABLE BODY FLUID-ABSORBING FABRIC PAD - Disclosed is a cleanable and reusable body fluid-absorbing fabric pad to move moisture including sweat and urine away from the skin of a wearer, the body fluid-absorbing fabric pad including, a diffusive fabric layer coming into contact with the skin of the wearer to remove moisture from the skin, an absorbent non-woven layer coming into contact with the diffusive fabric layer, the absorbent non-woven layer comprising at least 5 wt % of a superabsorbent fiber to remove moisture transported from the diffusive fabric layer, and a waterproof film coming into contact with the absorbent non-woven layer and exhibiting waterproofing properties and breathability. The absorbent non-woven layer is formed by needle-punching or thermally bonding superabsorbent fibers, polyethylene/polypropylene bi-component fibers and rayon fibers, wherein the diffusive fabric layer, the absorbent non-woven layer and the waterproof film are stacked and sewed to form the body fluid-absorbing fabric pad. The body fluid-absorbing fabric pad can utilize constituent fabrics having a multiple sublayer structure of the absorbent layer to increase diffusion rate of moisture from the skin of the wearer. | 07-14-2011 |
20120075744 | METHOD OF OPTIMIZING FLYING HEIGHT OF HEAD AND HARD DISK DRIVE MANUFACTURED BY THE SAME - A hard disk drive includes a controller that optimizes a flying height of a head of a hard disk drive. The controller determines an optimal flying height of a head based on a preset table value and an MRR value of a head measured during a hard disk drive manufacturing process and sets the head according the determined optimal flying height such that recording capacitance is improved. | 03-29-2012 |
20130305843 | Torque Angle Sensor - A torque angle sensor according to an exemplary embodiment of the present disclosure includes a torque sensor unit and an angle sensor unit at a housing centrally arranged with a rotation shaft, the torque sensor unit including a stator installed inside the housing, a torque magnet rotatably installed at a center of the stator in conjunction with rotary operation of the rotation shaft, a collector installed at the housing to transmit a magnetic field of the torque magnet, a magnetic device module formed with an individually operating first magnetic device and a second magnetic device in one package to detect the magnetic field transmitted by the collector, and a PCB (Printed Circuit Board) mounted with the magnetic device module, wherein the PCB is arranged to a direction perpendicular to an axial direction of the rotation shaft and installed at a distal end with the magnetic device module. | 11-21-2013 |
20140123770 | TORQUE MEASUREMENT DEVICE - Provided is a torque measurement device including a stator in which a space portion is formed by a first annular ring and a second annular ring having protrusion pieces, a ring-shaped magnet disposed in the space portion, and a collector assembly including a first collector member and a second collector member to form at least one insertion space in which a magnetic element is disposed, wherein the insertion space is formed by bending an end of the first collector member and an end of the second collector member toward the space portion. | 05-08-2014 |
