摘要： Provided is a light source unit that is to be joined to a slider to form a thermally-assisted magnetic recording head. The light source unit comprises: a unit substrate having a source-installation surface; a light source provided in the source-installation surface and emitting thermal-assist light; and a photodetector bonded to a rear joining surface of the unit substrate in such a manner that a rear light-emission center of the light source is covered with a light-receiving surface of the photodetector. The photodetector can be sufficiently close to the light source; thus, constant feedback adjustment with high efficiency for the light output of the light source can be performed. This adjustment enables light output from the light source to be controlled in response to changes in light output due to surroundings and to changes with time to stabilize the intensity of light with which a magnetic recording medium is irradiated.

摘要： Provided is a light source unit the weight of which can be reduced while ensuring power supply to the light source. The light source is configured to form a thermally-assisted magnetic recording head by being joined with a slider including an optical system that propagates light for thermal assist. The light source unit comprises: a unit substrate including a joining surface that faces an power-supply electrode of the slider; a first electrode provided on the joining surface; a second electrode provided on a source-installation surface and electrically connected to the first electrode; and a light source that includes two electrode layers and a light-emission center located in a light-emitting surface. The first and second electrodes eliminate the provision of a terminal electrode for light source on the source-integration surface. As a result, the weight of the light source unit can be reduced.

摘要： A method for manufacturing a thermally-assisted magnetic recording head is provided, in which joined are: a light source unit that includes a light source having a surface including a light-emission center on the joining surface side of a unit substrate; and a slider that includes an optical system having a light-receiving end surface reaching a back surface opposite to the opposed-to-medium surface. This method utilizes “semi-active alignment” that uses an alignment light, and comprises steps of: causing a light to enter the light source from a surface opposite to the light-emission center; detecting the light that has passed through the light source and is emitted from the light-emission center to align the light-emission center with the light-receiving end surface of the slider; and bonding the light source unit to the slider. This manufacturing method can achieve the alignment with a sufficiently high alignment accuracy in a short processing time.

摘要： A steam valve has: a valve casing; a valve seat; a main valve body slidable to abut to or to detach from the valve seat; a bypass valve body slidably disposed in the main valve body; a cylindrical flow guide surrounding the annular wall of the bypass valve body; and a strainer surrounding the main valve body and the flow guide. The bypass valve body has a steam passage and the annular wall that protrudes out of the main valve body when the bypass valve body is in an open position. The annular wall has steam inlet ports. The flow guide guides steam from outside to flow through a space between the annular wall and the flow guide so as to admit steam into the steam passage in the bypass valve body through whole peripheral part of the annular wall.

摘要： In the embodiment, a steam valve device has, a steam regulating valve, and an intermediate flow path connecting the main steam stop valve and the steam regulating valve. The main steam stop valve and the steam regulating valve respectively have: casings where flow paths are formed between horizontal inlet ports and outlet ports opened downward and valve seats are arranged in the flow paths; valve elements movable up and down in the casings; and valve rods for driving the valve elements. The valve rods extend upward, and they are pulled off upward in a direction to outside of the casings when opening the flow paths. The intermediate flow path changes the flow direction of main steam flowing out of the outlet port of the main steam stop valve from downward direction to horizontal direction to guide the main steam toward the outlet ports of the steam regulating valves.
