Title: Redundancy memory module and memory controller
Inventor: KUBO ATSUSHI
IPC: G06F11/00
Filed: 2002-04-09
Abstract: <P>PROBLEM TO BE SOLVED: To dynamically exchange abnormal DIMM (Double Inline Memory Module) during operation of a system.  <P>SOLUTION: ECC (error correcting code)/ChipKill circuits 4-0-4-4 generate, check, restore, and chipkill ECC. When writing the data, a parity generation/ check/restoration circuit 5 generates parity data, when reading the data, it checks the parity data, and when an abnormal DIMM is therein, the data are restored from the normal DIMM. A single parity DIMM 1-4 is thus prepared for four DIMMs 1-0-1-3, so that an abnormal DIMM is hot-pluggable when a trouble develops in the DIMM and the DIMM can be dynamically exchanged without memory degeneracy of an OS.  <P>COPYRIGHT: (C)2004,JPO

Title: Thin film magnetic head and its manufacturing method, and magnetic recorder
Inventor: MATONO NAOTO
IPC: G11B5/127
Filed: 2002-04-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide a thin film magnetic head in which the expansion/bend of a recording pattern due to the skew can be suppressed to improve the recording performance.  <P>SOLUTION: A main magnetic pole layer 12 is constituted so as to form the laminated structure with a lower main pole layer 12A having 1st saturated magnetic flux density J1 while being positioned at the medium inflow side and an upper main pole layer 12B having 2nd saturated magnetic flux density J2 larger than the 1st saturated flux density J1 while being positioned at the medium outflow side. When the magnetic flux flows in the main pole layer 12, since the flux saturation is not brought in the upper main pole layer 12B having the larger saturated flux density although the flux saturation is brought in the lower main pole layer 12A having the smaller saturated flux density, the magnetic flux preferentially flows mainly in the upper main pole layer 12B. Since the write operation by the main pole layer 12 is carried out in the upper main pole layer 12B mainly at the medium outflow side, the expansion of the recording pattern due to the skew is suppressed as compared with the case the saturated flux density of the whole main pole layer 12 is larger.  <P>COPYRIGHT: (C)2004,JPO

Title: System, method and apparatus for improving consistency of reverse oscillating lay(rol) during optical fiber cable manufacturing process
Inventor: MOSS PARRY A
IPC: H01B13/02
Filed: 2002-04-12
Abstract: PROBLEM TO BE SOLVED: To provide a method, an apparatus and a system for improving consistency of reverse oscillating lay(ROL) during an optical cable manufacturing process. SOLUTION: A torque capstan receives an optical fiber cable from an ROL machine which places reverse oscillating lay on the core of an optical cable, but also generates some undesirable fluctuating back-tension in a direction opposite to a direction in which the optical fiber cable is being pulled during manufacturing of the optical cable. The optical cable comprises a plurality of subunit cables. A drive system coupled to the torque capstan is controlled by a control system in such a way that the torque capstan applies a certain amount of force to the optical cable in a direction substantially parallel to the direction in which the optical cable is being pulled during manufacturing process.  The certain amount of force applied to the optical fiber cable reduces undesirable fluctuating back-tension placed on the optical cable during the manufacturing process, thereby improving reverse oscillating lay (ROL) consistency, which improves the quality of the manufactured optical cable.
