Title: Case hardening steel for cold forging excellent in grain coarsening resistance
Inventor: MORIMOTO TORU
IPC: C22C38/28
Filed: 1991-01-24
Abstract: PURPOSE:To obtain a case hardening steel for cold forging excellent in grain coarsening resistance, in a case hardening steel having a specified compsn. by adding a specified amt. of Nb and specifying the amounts of Sol.Al and N. CONSTITUTION:This case hardening steel contains, by weight, 0.10 to 0.30% C, <=0.50% Si, 0.30 to 1.80% Mn, 0.020 to 0.050% Sol.Al, 0.0090 to 0.0140% N, 0.010 to 0.100% Nb, <=0.005% Ti, <=2.0% Cr and/or <=1.0% Mo and the balance Fe. Sol.Al and N form AlN and the AlN are finely dispersed into a steel to prevent the coarsening of crystalline grains, but in the case the content of Sol.Al exceeds the upper limit, Al2O3 series inclusions increase to cause its defects, and furthermore, AlN condenses and coarsens to exert adverse effect on the refining and dispersing of Nb carbides. As for N, in the case of more than the upper limit, by the deterioration in its toughness and the intercrystalline precipitation of AlN, the cracking of the outside surface of a mold is caused. Nb is extremely effective for the suppression of the coarsening of the crystalline grains, but even in the case of more than the upper limit, its saturation occurs. Furthermore, even at the time of subjecting the above steel to carburization at a high temp. without executing heat treatment before the carburization till its cold forging having high working degree, the coarsening of the crystalline grains can be prevented.

Abstract: PURPOSE:To make a device small in size, to prevent a temperature increase, and to obtain a high-performance printing head for dot printer having no possibility of a functional trouble, by attracting and releasing an armature without using an electromagnet for driving a printing wire. CONSTITUTION:A permanent magnet 10 as a drive means is disposed opposedly to a center part 6 of an armature 5, the whole or the center part 6 of which is made of a ferromagnetic body. On the surface of the permanent magnet 10 opposed to the center part 6, a superconductor 11 is so mounted as to interrupt the magnetic field of the permanent magnet 10. The magnetic characteristics of the superconductor 11 is varied by passing or cutting an electric current to the superconductor 11, whereby the armature 5 is rotated to drive a printing wire 7. Therefore, the drive of the printing wire 7 is made possible without using an electromagnet.

Abstract: PURPOSE:To enable accurate detection of a position regardless of a spacing change, by a method wherein a fine magnetization is performed reversely to suppress a leak magnetic field at both ends of a magnetized zone to eliminate an abnormal output otherwise developed at an end of the magnetized zone. CONSTITUTION:As an MR element R2 moves through 101-103..., an output waveform voltage is detected. Here, as a magnetic field exists at the portion 101 across the width of a sensor pattern of the element R2 to generate an abnormal output. To eliminate the magnetic field across the width of the sensor pattern, magnetization is performed in a non-magnetized zone at a pitch of about 0.2-0.4 p when a magnetization pitch in a magnetized zone is set at (p). As a result, an abnormal output at a portion 51 can be eliminated by suppression. Thus, a fine magnetization applied to the non-magnetized zone at tracks of a magnetic disc can eliminated a magnetic field otherwise developed across the width of an MR sensor except for the magnetized zone, eventually getting rid of abnormal outputs completely.
