A thin-film magnetic head is manufactured as follows. First, a base insulating layer having a magnetic pole forming depression sunken into a form corresponding to the main magnetic pole layer is formed, a stop film for CMP is formed such as to fill the magnetic pole forming depression, and then a magnetic layer is formed on the stop film. Next, the magnetic layer is separated by forming a separation groove substantially surrounding the magnetic pole forming depression on the outside thereof, and thus separated magnetic layer is formed with a cover insulating film adapted to cover the whole upper face. The surface is polished by CMP until the stop film is exposed, so that the part of magnetic layer remaining on the inside of the magnetic pole forming depression is used as the main magnetic pole layer. Further, a recording gap layer, a write shield layer, and a thin-film coil are formed.

A manufacturing method for a layered chip package including a stack of a plurality of layer portions includes the steps of: fabricating a layered substructure by stacking a plurality of substructures each including a plurality of layer portions corresponding to the plurality of layer portions of the layered chip package; and fabricating a plurality of layered chip packages by using the layered substructure. The step of fabricating the layered substructure includes: fabricating a first and a second pre-polishing substructure; bonding the first pre-polishing substructure to a jig such that a first surface of the first pre-polishing substructure faces the jig; forming a first substructure by polishing a second surface of the first pre-polishing substructure; bonding the second pre-polishing substructure to the first substructure such that a first surface of the second pre-polishing substructure faces the polished surface of the first substructure; and forming a second substructure by polishing a second surface of the second pre-polishing substructure.

A constant velocity universal joint includes an inner race having an outer peripheral face on which inner grooves are formed, an outer race having an inner peripheral face on which outer grooves are formed, a plurality of balls each engaging with each pair of inner groove and outer groove, and an annular cage disposed between the inner race and the outer race and including window portions for retaining respective balls. A coefficient of sliding friction between the ball and a rolling face on the inner groove with which the ball is in contact, and a coefficient of sliding friction between the ball and a rolling face on the outer groove with which the ball is in contact are larger than a coefficient of sliding friction between the ball and a sliding face on the window portion with which the ball is in contact.

A thin-film magnetic head has a laminated construction comprising a main pole layer having a magnetic pole tip on a side of the medium-opposing surface opposing a recording medium, a write shield layer opposing the magnetic pole tip forming a recording gap layer, on the side of the medium-opposing surface, and a thin-film coil wound around at least a portion of the write shield layer. The thin-film magnetic head has an upper yoke pole layer having a larger size than the portion of the main pole layer which is more distant from the medium-opposing surface than the recording gap layer, wherein the upper yoke pole layer is joined to the side of the main pole layer which is near the thin-film coil.

A chair is equipped with a leg column 1, a seat 3, and a back support 4. An intermediate supporting member 9 is fitted to an upper end of the leg column 1, the seat 3 and a back frame 5 are fitted to the intermediate supporting member 9, and the back support 4 is fitted to an upper end of the back frame 5 via a joint unit 11. The seat 3 has an elongated shape when viewed from the top, and is fitted to the intermediate supporting member 9 to swivel horizontally. The back support 4 can be turned freely around a first axis 13 and also can be turned freely around a second axis 12. Since the seat 3 and the back support 4 can be changed into various modes, a using mode of the chair can be changed variously.

A communication apparatus which communicates with an external apparatus by receiving a communication request transmitted from the external apparatus based a call-out number uniquely allocated to the communication apparatus, includes: a communication request receiver which receives identification information allocated to the external apparatus and the communication request independently of a call-out number of the external apparatus; a display which displays information; an information storage which stores an association table associating the identification information of the external apparatus with apparatus information used for displaying in reception of the communication request from the external apparatus; and a display controller which, when the communication request receiver receives a communication request with identification information, displays apparatus information recorded in the association table stored in the information storage on the display, which is associated with identification information matching the identification information received with the communication request.
摘要:
The present invention provides an ion implantation method which can achieve sufficient throughput by increasing a beam current even in the case of ions with a small mass number or low-energy ions, an SOI wafer manufacturing method, and an ion implantation system. When ions are implanted by irradiating a semiconductor substrate with an ion beam, predetermined gas is excited in a pressure-reduced chamber to generate plasma containing predetermined ions, a magnetic field is formed by a solenoid coil or the like along an extraction direction when the ions are extracted to the outside of the chamber, and the ions are extracted from the chamber with predetermined extraction energy. The formation of the magnetic field promotes ion extraction, but this magnetic field has no influence on an advancing direction of the extracted ions. Therefore, the ion beam current can be kept at a high level-to contribute to the ion implantation.
