Title: Production of tempering-free-type ti-b type high carbon steel sheet
Inventor: FUKUI KIYOSHI
IPC: C22C38/14
Filed: 1991-10-04
Abstract: PURPOSE:To obtain the steel sheet for chains, seat belt fittings, etc., excellent in formability and toughness by subjecting a plate of a Ti-B type high C steel with a specific composition having a specific thickness to plastic working, to soaking at specific temp., and then to water- or oil-quenching. CONSTITUTION:A hot rolled steel plate of <=6mm plate thickness, which has a composition consisting of, by weight, 0.15-0.40% C, <=0.35% Si, 0.6-1.50% Mn, <=0.030% P, <=0.020% S, 0.005-0.1% Ti, 0.01-0.20% sol.Al, 0.0020-0.012% N, 0.0003-0.0030% B (where B<=0.0032-0.014Xsol.Al-0.029XTi), and the balance Fe, is used. This steel plate is subjected to plastic working, to soaking at a temp. in the region between Ac3 and 950 deg.C, and then to water- or oil-quenching. In the above steel, the precipitation of cementite is inhibited by regulating C content to the value in the above range and hardenability is secured by adding B and also the hardenability due to B is secured by adding Ti, and further, the abnormal growth of austenite grains is inhibited by precipitating AlN and TiN.

Inventor: ISHIDA ISAO
IPC: B62D49/00
Filed: 1989-10-02
Abstract: PURPOSE:To enable simple and accurate automatic change-over of steering operation by steering front and rear wheels interlockingly at the time of work (seedlings planting) steering, and steering only the front wheels interlockingly at the time of turning steering. CONSTITUTION:At the time of steering to operate a working (seedlings planting) device 28 mounted at a body 1, front wheels 6 and rear wheels 12 are steered interlockingly in the same direction, so that the body 1 is steered to the left or right approximately parallel to the straight work travel, thus moving a work position. At the time of entering into turning steering after work steering, only the front wheels 6 are interlockingly steered to perform turning on the basis of turning steering or operation for turning steering. The steering operation is thereby facilitated, and the body 1 runs as parallel as possible. Moreover, travel correction is performed in a short time, and turning travel is maintained desirably.

Furthermore, by suitably controlling the producing process, orientation properties can highly be imparted to the structure of the crystal grains after secondary recrystallization. As a result, high B8 (magnetic flux density at 800 A/m) can be obtd., and B8 is preferably regulated to >=1.85.

Title: Scanning tunneling microscope
Inventor: MIYAMOTO YASUSHI
IPC: G01N37/00
Filed: 1989-10-04
Abstract: PURPOSE:To keep a servo system in a proper state at all times irrespective of the state of the surface of a sample by scanning a probe while adjusting a distance between the probe and the sample on the basis of a detection signal of a tunnel current. CONSTITUTION:A Z stage 14 is moved downward under the control of a CPU 1a and a tube scanner 15 is made to extend near a reference length and to reach a tunnel area. While a Z servo voltage from a servo circuit 19 is read by the CPU 1a through an A/D conversion element 7, thereafter, a Z D/A output of a D/A converter 31 is controlled to approach 0V. At a time point when the Z serve voltage becomes 0V, the Z D/A output of the converter 31 is fixed. As the result, a state brought about by impression of a voltage obtained by amplifying 20 an addition output of the Z D/A output and the Z servo voltage is held. In this way, a deviation of the impressed voltage based on the resolution of a rough motion from a reference voltage can be corrected (correction of the Z servo voltage) by adjusting the Z D/A output.

Title: Continuous casting method
Inventor: KUDO JUNICHI
IPC: B22D11/18
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To lessen hydraulic shock at the time of automatic charging by previously setting a spool valve in a servo cylinder at a neutral position then switching the setting at the time of switching the operation of a stopper from manual operation to automation. SOLUTION: Molten metal is supplied from a tundish 1 into a casting mold 2 while its flow rate is controlled by a stopper lifting device 3. The rotation of the stepping motor 4 of this lifting device 3 is converted to the linear displacement of the sprue valve 6. An electrohydraulic servo cylinder 5 moves a piston rod 7 so as to return the valve 6 to the neutral position. The stopper 8 of the lifting device 3 is moved vertically by the movement of the rod 7. The valve 6 does not exist at the neutral position when the stopper 8 is manually operated by turning off the supply oil pressure. The motor 4 is rotated to return the valve 6 to the neutral position when the manual operation is completed. The supply oil pressure is turned on to switch the operation to the automatic operation.  As a result, the fluctuation in the molten steel surface in the casting mold 2 is lessened and the smooth switching between the manual operation and the automatic operation is ensured.
