Abstract: PURPOSE: To provide good ferrite-pearlite structure and considerably decrease the rate of formation of hydrogen defects by performing the cooling after hot working under the specific conditions in the process for the production of thick-walled steel materials.  
     CONSTITUTION: In the process of producing thick-walled steel materials such as plates, thick-walled forged steel products, semiprocessed goods like bloomed slabs, blooms and billets, and large-sized steel rods, the structure of macrosegregated part is made into the ferrite-pearlite structure of the smallest seusitivity to the hydrogen embrittlement in the cooling process from the austebite region after the heating or working in the austenite temperature region. To this end, the thick-walled steel materials having undergone hot working or the thick-walled steel materials having undergone diffusion soaking treatment are cooled at the cooling rate [CR]°C/min. shown by the formula [I]. [Mn eq denotes the Mn equivalent (wt%) in the macrosegregated portions of the steel materials.] The rate of formation of the hydrogen defects which become the target for detection in ultrasonic flaw detection test decreases considerably.

Title: Magnetic recording/reproducing device
Inventor: MASUDA EIJI
IPC: G11B5/02
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To correct an imbalance in the direction of the magnetic domain of an MR element so as to make recovery from a reading error by stopping the flowing of a bias current supplied to the MR element once when no recovery is made from the reading error even if re-reading is repeated. SOLUTION: When a reading error occurs during reproducing, re-reading is performed from a sector in which the error occurs until a predetermined number of times is reached according to a program saved inside a microprocessor unit 6, and recovery is made from the reading error. When no recovery is made because of a wiggle produced by the imbalance of the direction of the magnetic domain of an MR element 1 even if re-reading is repeated, the MR element 1 is driven to the outside of a servo region. After a bias magnetic field is eliminated by turning ON/OFF a bias current 1b, by applying a bias magnetic field again to the MR element, the direction of the magnetic domain of the MR element 1 is moved. Thus, the imbalance of the magnetic domain of the MR element 1 is corrected and recovery is made from a reading error caused by a wiggle.
