20110157750 | TOP BOND PAD FOR TRANSDUCING HEAD INTERCONNECT - A slider includes a slider body having a first side and edges defined adjacent to the first side, at least two separate insulators each adjacent to the first side of the slider body and supported by the slider body, and a conductive trace adjacent to each of the at least two separate insulators and opposite the first side of the slider body. The at least two separate insulators each are in physical contact with the slider body along the first side of the slider body such that the at least two separate insulators are physically attached to the slider body to electrically insulate each conductive trace from the slider body. | 2011-06-30 |
20110157751 | APPARATUS AND METHOD FOR PROTECTING OVERVOLTAGE OF HIGH VOLTAGE INVERTER - Disclosed herein is an overvoltage protection apparatus and method of a high voltage inverter adapted to protect a load without any adverse effect from an overvoltage aroused by voltage fluctuation attributable to an impedance difference among an inverter, a load and a cable connected between the inverter and the load, wherein the apparatus and method converts a voltage command signal given as a digital signal into an analog reference signal by a main control unit, compares the analog reference voltage with a sawtooth wave having a predetermined voltage level and frequency in order to generate a PWM (Pulse Width Modulation) signal, determines the pulse width of the PWM signal, and converts the pulse width of the PWM signal to have a predetermined time interval in a case the pulse width of the PWM signal is less than a predetermined time interval. | 2011-06-30 |
