Abstract: PURPOSE:To eliminate the need for an exclusive circuit for read or a device for write data for exclusive use of positioning by reading a data written on a magnetic disk and positioning the magnetic head so as to maximize the readout waveform of the data. CONSTITUTION:A signal represented by a waveform 14 is outputted from a differential amplifier 18 when a head core part 1 is at a correct position 11 of a recording track 10. Further, a signal represented by a waveform 15 is outputted when the head core art 1 is at a position 12, and a signal of a waveform 16 is outputted when the head core part is at a position 13. When a signal except zero level is outputted from comparators 31, 32, a control circuit 33 outputs a drive signal to a step motor 7 so as to output the signal other than zero level from the comparators 31, 32. That is, the signal maximizing the readout waveform of the head core part 1 is outputted to the step motor 7 from the control circuit 33.

Title: Production of steel and high strength member excellent in cold-forgability and delayed fracture characteristic
Inventor: SHIRAGAMI TETSUO
IPC: C22C38/00
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To produce a steel excellent in cold-forgability and delayed fracture characteristic by incorporating specific ratios of C and Ni. SOLUTION: This steel contains, by weight, 0.1%-<0.2% C and 3-12% Ni. C is needed to secure the necessary tensile strength, but in the case of exceeding the upper limit, the strength as rolling is too high and the cold-forging is difficult to perform. Ni improves the hardenability and also, the invasion of hydrogen under corrosion atmosphere is restrained and the delayed fracture characteristic is improved. In the case of being less than the lower limit of Ni, the material having the strength of >1300 MPa can not be obtd. Production of a high strength member using this steel is as the following. The steel adjusted to the above composition is cold-forged and successively, after applying quenching and cold-form rolling, a low temp. tempering is executed.  The screw form rolling (cold-form rolling) is ordinarily executed before quenching, but in this producing process, this cold-form rolling is executed after quenching, and thereafter, the tempering is executed to improve the delayer fracture characteristic. The obtd. member is suitable to high strength bolt, PC steel bar, etc.
