An electrical machine including a casing (1), an oil inlet hole (7), an oil passage (2), oil outlet holes (3), a stator retainer (8), a casing end cover (10), a stator iron core (5), winding coils (6), slot insulations (12) and oil-guides (4). The oil passage (2) is located inside the casing (1) and links with the oil inlet hole (7) of the casing (1) and the oil outlet holes (3) of the stator retainer (8). The oil outlet holes (3) are located above the winding coils (6) and the oil-guides (4) are located between the oil outlet holes (3) and the winding coils (6). Oil entering from the oil inlet hole (7) pours onto the winding coils (6) by the guidance of the oil-guides (4) after flowing through the oil passage (2) and flowing out of the oil outlet holes (3). The winding coils of the electrical machine can be effectively cooled and the electrical machine can achieve higher thermal durability. An oil cooling method for the electrical machine is also provided.

A plant growth facilitating apparatus, for receiving and growing a plant, includes an accommodating body and a light emitting unit. The accommodating body defines an accommodating space for receiving the plant. The light emitting unit has a first LED set for emitting a red light in increasing the growth speed of the plant and a second LED set for emitting a blue light in promoting the photosynthesis of the plant. The wavelength range of the red light is 620-760 nanometer, and the wavelength range of the blue light is 360-480 nanometer. The light emitting unit is used for emitting light toward the accommodating space of the accommodating body, and the longest path of the light from the light emitting unit to the accommodating body is smaller than 1 meter.
摘要:
A magnetic write head having a tapered trailing edge and having a magnetic layer formed over a trailing edge of the write pole at a location recessed from the ABS, the magnetic layer being separated from the trailing edge of the write pole by a thin non-magnetic layer. The thin non-magnetic layer is preferably sufficiently thin that the magnetic layer can function as a portion of the write pole in a region removed from the ABS. A trailing magnetic shield is formed over the write pole and is separated from the write pole by a non-magnetic trailing gap layer. A non-magnetic spacer layer can be formed over the magnetic layer to provide additional separation between the magnetic layer and the trailing magnetic shield.

Methods of making write poles for perpendicular magnetic recording write heads. The bevel angle of the write pole for a perpendicular magnetic recording write head affects the performance of the write head. By forming reinforcement layer on the polymeric underlayer mask to enhance the mask durability during ion mill and tapering the polymeric underlayer above the non-magnetic mill mask layer using oxygen and nitrogen based reactive ion etch process, the bevel angle of the magnetic write pole can be increased greatly to meet the demands of the next and future generations of magnetic recording write heads.
摘要:
A method for manufacturing a magnetic write pole of a magnetic write head for perpendicular magnetic recording. A magnetic write pole material is deposited, followed by union milling hard mask, a polymer mask under-layer followed by a dielectric hard mask material, followed by a photoresist. The photoresist is patterned to define a write pole shape and the shape of the patterned photoresist is transferred onto the underlying dielectric hard mask by a novel reactive ion etching that is performed in a chemistry that includes one or more fluorine containing gases and He. The presence of He in the reactive ion etching tool helps to improve the profile of the patterned dielectric hard mask. In addition, RIE parameters such a gas ratio (e.g. CF4 to CHF3 gas ratio) and power ratio (e.g. source power to bias power) are adjusted to optimize the profile of the patterned dielectric mask.
摘要:
A method for manufacturing a magnetic write pole using a mask that includes a multi-layer hard mask. The multi-layer hard mask hard mask includes a first hard mask layer that is constructed of a Si containing material that can be spun on and a second hard mask material that is deposited by a deposition process such as sputter deposition. The first hard mask layer has optical properties that allow it to function well as a bottom anti-reflective coating (BARC) and also has optical properties that match well with an underlying image transfer layer. The second hard mask material has good selectivity for reactive ion etching so that it functions well as a RIE hard mask.
摘要:
A method for manufacturing a magnetic write head for perpendicular magnetic recording. The method includes forming a write pole, and then depositing a refill layer. A mask structure can be formed over the writ pole and refill layer, the mask structure being configured to define a stitched pole. An ion milling or reactive ion milling can then be performed to remove portions of the refill layer that are not protected by the mask structure. Then a magnetic material can be deposited to form a stitched write pole that defines a secondary flare point. The stitched pole can also be self aligned with an electrical lapping guide in order to accurately locate the front edge of the secondary flare point relative to the air bearing surface of the write head.
摘要:
A method for manufacturing a magnetic write head that avoids the challenges associated with the formation of fence structures during write pole definition. A magnetic write pole material is deposited. A mask structure is deposited over the magnetic write pole material. The mask structure includes a first hard mask, a marker layer, a physically robust, inorganic RIEable image transfer layer, a second hard mask structure over the image transfer layer and a photoresist layer over the second hard mask. A reactive ion etching process can be used to transfer the image of the photoresist mask and second hard mask layer onto the image transfer layer. An ion milling is performed to define the write pole. A layer of non-magnetic material such as alumina is deposited. An ion milling is performed until the marker layer has been reached, and another reactive ion etching is performed to remove the remaining hard mask.
