Abstract: According to one embodiment, a head includes a head slider including a bearing surface and configured to fly by an airflow between the recording medium surface and the bearing surface, and a recording element and a reproduction element arranged in an outflow end portion of the head slider with respect to the airflow. The bearing surface includes a first pressure generating portion on an inflow end portion of the head slider with respect to the airflow, configured to generate a pressure, a second pressure generating portion on the outflow end portion, configured to generate a pressure, and a third pressure generating portion between the first and second pressure generating portions at a transverse central part of the bearing surface, configured to generate a pressure higher than that generated by the first pressure generating portion and lower than that generated by the second pressure generating portion.

Abstract: According to one embodiment, a head slider includes a magnetic head, a medium facing surface, a flow-in end surface, a flow-out end surface, side surfaces, and an absorbing structure. The magnetic head reads and writes information with respect to a magnetic recording medium. The medium facing surface faces the magnetic recording medium. From the flow-in end surface, an airflow generated by rotation of the magnetic recording medium flows in. To the flow-out end surface, the airflow is guided from the flow-in end surface through the medium facing surface. The side surfaces are located on both sides of the medium facing surface. The absorbing structure is provided to at least one of the flow-out end surface and the side surfaces. The absorbing structure absorbs flowing substances guided with the airflow.

Abstract: There is provided a chamber open to the outside through openings through which a solder-adhered object is passed and the chamber having a heating/melting area, a carrying mechanism for carrying the solder-adhered object into the heating/melting area, a formic-acid supplying means for supplying a formic acid into the heating/melting area, an exhausting means for exhausting a gas from the heating/melting area and its neighboring area to create a lower pressure area in the heating/melting area as compared to the pressure of outside the chamber, heating means for heating directly or indirectly the solder-adhered object in the heating/melting area, and an air-stream suppressing means for disturbing a gas flow between the heating/melting area and the carrying areas.

Abstract: There are provided a chamber having openings which are opened to an outer air and through which a solder-adhered object w is passed and having a heating/melting area and carrying areas arranged adjacent to the heating/melting area, a carrying mechanism for carrying the solder-adhered object w into the heating/melting area, a formic-acid supplying means for supplying a formic acid into the heating/melting area, an exhausting means for exhausting a gas from the heating/melting area and its neighboring area to lower a pressure in the heating/melting area rather than an outer air, heating means for heating directly or indirectly the solder-adhered object w in the heating/melting area, and air-stream suppressing means for disturbing a gas flow between the heating/melting area and the carrying areas.
