Abstract: Embodiments described herein generally relate to a magnetic read head wherein read sensitivity distribution is made asymmetric in the off-track direction. The method of making the magnetic head is also disclosed. The read head may comprise a magneto-resistive effect element with an asymmetric structure around the element in the off-track direction and the read sensitivity profile in the off-track direction may also be asymmetric.

Abstract: Embodiments of the present invention generally include magnetoresistive heads, such as read heads, having a sensor structure and side shields disposed adjacent to the sensor structure. The distance between the side shields and the sensor structure increase in a direction from an ABS in the off-track direction. The magnetoresistive heads may include tapered surfaces on the side shields or sensor structure, or may include stepped surfaces on the side shields or sensor structure.

Abstract: An auto focus (AF) circuit includes a high-pass filter and band-pass filter having mutually different frequency characteristics. During contrast AF control prior to an actual shooting, AF evaluation values acquired by using the high-pass filter are used most preferentially in detecting the lens focusing position of a focus lens. In this way, the high-pass filter that emphasizes and extracts high frequency band components, which increase in image data when shooting a typical subject, is set to be used preferentially, thereby making it possible to perform high-precision focusing control with respect to various kinds of subjects.

Abstract: The present invention provides a high-efficiency absorption refrigerating machine which can recover heat from a heat source and can efficiently recover heat from an internal cycle. The absorption refrigerating machine includes an evaporator, an absorber (A), a condenser (C), a high-temperature regenerator (GH), a low-temperature regenerator (GL), a low-temperature solution heat exchanger (LX), and solution paths and refrigerant paths by which these units are connected. The absorption refrigerating machine further comprises two branch solution paths branched from a solution supply path through which a dilute solution is introduced from the absorption (A) to the high-temperature regenerator (GH). On one of the branch solution paths, there is disposed a drain heat exchanger (DX) operable to perform heat exchange between the dilute solution in the branch solution path and an exhaust heat source which has heated the high-temperature regenerator (GH).

Abstract: The present invention provides an image-capturing apparatus having the function of keeping on properly achieving focus on a subject while dealing with movement of the apparatus (camera), movement of the subject, and the like. When a subject moving state is detected by a panning/subject moving state detector in a full-time AF operation, an image acquiring part enlarges an AF evaluation area for obtaining image data in the direction substantially perpendicular to the ground. After that, under control of a driving controller, while driving an imaging lens forward and backward in the optical axis direction around the focus position of last time as a center, the image acquiring part acquires a plurality of pieces of image data from the AF evaluation area.

Abstract: An ignition coil includes a primary winding, an auxiliary primary winding and an ignition high voltage generating secondary winding which are wound on the same core. The primary current from the generating coil of a magneto flows to the base of a transistor through the primary winding of the ignition coil. The primary current flowing through the primary winding induces a voltage across the auxiliary primary winding and the induced voltage is applied between the base and emitter of the transistor. At the time of ignition, the primary current flowing to the base of the transistor is shunted by a semiconductor switching element so that the transistor is turned off and the current flowing through the auxiliary primary winding is interrupted, thus generating a high voltage across the secondary winding of the ignition coil.
