摘要： A protection film is layered over the trailing or outflow end surface of a slider body in a head slider for a recording medium drive. A head element is embedded within the protection film. The head element generates heat in response to the supply of an electric current. The heat causes thermal expansion of the protection film. The tip end of the head element thus excessively approaches the recording disk beyond the medium-opposed surface of the head slider. The flying height of a protection protuberance is set smaller than a flying height of the head element even when the protection film suffers from thermal expansion. The protection protuberance is allowed to trace an orbit closer to the recording medium than the orbit of the head element. The protection protuberance is allowed to collide against obstacles on the recording medium in front of the head element.

摘要： The present invention provides wave signal processing systems and methods that estimate a wave source direction and use that information to realize sharp directivity even in the case of a device that is compact or that has limited calculating capacity. A wave signal processing system of the present invention is provided with at least one sensor group made of at least two sensors, determines a difference signal between wave signals detected by any two sensors in at least one of the sensor groups and determines a differential signal of a wave signal detected by at least one sensor, and based on a combination of a sign of the difference signal and a sign of the differential signal and a positional relationship of the sensors, determines the sign of a delay time between the wave signals that are detected by the two sensors and determines the direction of the wave source based on whether the sign of the delay time is positive or negative.

摘要： A medium-opposed surface of a slider body is hemisected into first and second areas by the centerline extending in the longitudinal direction of the slider body. The second area is designed to generate a positive pressure larger than that generated at the first area when a load acting on the slider body in a direction toward a recording medium decreases. The head slider of the type is allowed to enjoy the imbalance of the lift on the slider body. This imbalance can be utilized to intentionally induce increases in the roll angle and the pitch angle of the slider body. The increase in the roll and pitch angles causes disappearance of the lift and the negative pressure generated at the medium-opposed surface. The head slider can reliably be distanced from the moving surface of the recording medium solely with the assistance of the airflow acting on the medium-opposed surface.

摘要： An input signal is input via an input part. A plurality of signal section candidate detecting parts having different detection algorithms detect an intended signal section candidate and a noise signal section candidate from the input signal. A signal section classifying part is notified of detection results from the respective signal section candidate detecting parts, and classifies the respective signal section candidates based on a combination of the detection results. The signal section classifying part classifies a signal section candidate, which is detected as an intended signal section candidate by all the signal section candidate detecting parts, as an intended signal section, classifies a signal section candidate, which is detected as a noise signal section candidate by all the signal section candidate detecting parts, as a stationary noise signal section, and classifies a signal section candidate, which is detected as an intended signal section candidate by any of the signal section candidate detecting parts and detected as a noise signal section candidate by either of the signal section candidate detecting parts, as a non-stationary noise signal section.

摘要： An image sensor, a voice sensor, an auxiliary sensor part (infrared sensor, etc.), a total analyzing part, and an application communicate with each other through data/control signal communication units. Each sensor provides feedback on its signal detection results and control information used by the other sensors for determining a range of a detection target and a detection sensitivity at a time of subsequent signal acquisition, to the other sensors through the communication units. The total analyzing part investigates whether or not there is inconsistency among the results detected by the respective sensors, and provide control information to each sensor. Each sensor determines a range of a signal detection target and a detection sensitivity based on the obtained information, and acquires a signal in accordance with the determination.
