In the initial setting process, driving power to a heater is increased gradually, from a state where the heater arranged at a position in proximity to the magnetic head in the slider is not driven, until the magnetic head makes contact with the magnetic disk. Then, in each stage, an electrical resistance value of the sensor arranged at a position in proximity to the magnetic head in the slider, which is increased due to the heat from heater, and either an approach distance of the magnetic head toward the magnetic disk or the flying height of the magnetic head from the magnetic disk are acquired. Then, basic data is prepared by obtaining the relationship between a variation of the electrical resistance value of the sensor and the flying height of the magnetic head from the magnetic disk, which is obtained in each stage or which calculated from the approach distance in each stage. In the flying height detecting process, an electrical resistance value of the sensor is determined, and a variation of the electrical resistance value is calculated from the determined values. Then, the flying height of the magnetic head from the magnetic disk in the state where the electrical resistance value was determined is obtained based on the basic data obtained in the initial setting process, using the calculated variation of the electrical resistance value.	09-01-2011

20110122036	LIGHT TRANSMISSIBLE RESONATORS FOR CIRCUIT AND ANTENNA APPLICATIONS - Provided is a circuit for an electronic device having a non-planar transparent resonator. The transparent resonator is mounted on said circuit so as to at least partially occupy a footprint of another component of the circuit. The transparent resonator forms part of a light pathway on said circuit for transmitting light to or from said another component. Also provided is a transparent dielectric resonator antenna (DRA) for optical applications. Since the DRA is transparent, it can let light pass through itself and, thus, the light can be utilized by an optical part of a system or device. The transparent DRA can be placed on top of a solar cell. Since the DRA does not block the light, the light can reach the solar cell panel and power can be generated for the system or device. The system or device so obtained is very compact because no extra footprint is needed within the system or device for the DRA. It finds application in compact wireless applications that need a self-sustaining power device.	05-26-2011

20110221938	Optical Black-Level Cancellation for Optical Sensors Using Open-Loop Sample Calibration Amplifier - A Optical Black Pixel (OBP) cancellation circuit corrects offsets in sensors in a CCD/CMOS image sensor when reading dark pixels such at the periphery. A pixel voltage is switched to a sampling capacitor during two phases of the same pixel pulse. Sampling capacitors and feedback capacitors connect to differential inputs of an amplifier. An accumulating capacitor accumulates voltage differences and generates a common-mode voltage that is fed back to another sampling capacitor that stores an amplifier offset. The sampling capacitor and accumulating capacitor and their associated switches form a discrete-time first-order low-pass filter that filters the pixel voltage during the first phase. In the second phase the amplifier acts as a unity-gain amplifier to output an average of the pixel voltage differences generated during an OBP time when blackened or covered pixels are read from the image sensor.	09-15-2011

The present invention also provides a pharmaceutical composition comprising an arginine reducing compound, such as pegylated human arginase I, and an anti-neoplastic compound, such as	11-27-2008
20100247508	SITE-DIRECTED PEGYLATION OF ARGINASES AND THE USE THEREOF AS ANTI-CANCER AND ANTI-VIRAL AGENTS - Mono-pegylated arginase conjugate and method producing thereof. The mono-pegylated arginase is homogeneous in molecular weight and shows therapeutic effect for treating cancers and viral infections. The method of producing such arginase conjugate has a main step of genetically modifying the gene encoding an arginase so that the PEG moiety can attach to the enzyme at a predetermined, specific intended site. This is achieved by removing the PEG attaching amino acid residues at undesirable sites while keeping (or adding, if necessary) the one at the desirable site of the enzyme. Two exemplary mono-pegylated arginase conjugates so produced are human arginase I (HAI) where a polyethylene glycol (PEG) moiety is site-specific covalently bonded to Cys	09-30-2010
