Title: Production of high yield sprength non-magnetic bar steel
Inventor: SHINODA KENICHI
IPC: C21D8/06
Filed: 1979-02-02
Abstract: PURPOSE:To considerably improve the yield strength of high C high Mn austentie non-magnetic steel by adding V to said steel and applying the specific heat treatment according to the addition amount of V. CONSTITUTION:V is added at 0.30-0.60% or 0.69-1.00% to the high C high Mn austentite non-magnetic steel containing C; 0.70-1.20%, Mn; 11.0-16.0%. At the time of hot rolling this steel material to a steel bar, the draft of the final pass is made 10-40%. In addition, if the V addition amount is 0.30-0.60%, the rolling temperature of the final pass is made 800-950 deg.C and if the V addition amount is 0.60-1.00%, the rolling temperature of the final pass is made 800-1050%C. In this way, the release of working strain during hot rolling is suppressed and V carbides are finely deposited during cooling after the rolling, thus the non-magnetic steel of high yield strength is produced through double strengthening of work strengthening and precipitation strengthening.

Title: Method for coating tubular body with slurry
Inventor: KURODA HIROAKI
IPC: B05D7/14
Filed: 1984-01-24
Abstract: PURPOSE:To apply a slurry to the inner surface of a pipe in a thicker and more uniform state as compared with the outer surface thereof, by immersing a pipe in a stock slurry and removing said pipe from the slurry while rotating the same in an upright state. CONSTITUTION:A pipe 3 being an article to be coated is held by a holder 5 and immersed in the stock slurry 2 such as a ceramic or enamel slurry stored in a container 1 in an upright state. When the hollow pipe 3 is rotated in the slurry 2, the surry 21 in the pipe 3 begins to also rotate slightly late and, when rotation is performed in the same degree as the pipe 3, the slurry 21 in the pipe 3 reaches a state pressed to the inner surface side of the pipe 3 by centifugal force. On the other hand, the volume of the slurry 22 in the outer surface side of the pipe 3 is large while the rotation of the slurry 22 following the rotation of the pipe 3 becomes fast locally in the vicinity of the outer periphery of the pipe 3 and, therefore, the viscosity of said slurry 22 becomes low. As a result, if the pipe 3 is removed from the slurry 2 in a rotary state, a desired pipe having a thick film in the inner surface side thereof can be obtained.

Filed: 1987-01-22
Abstract: PURPOSE:To correct the constant length control value with high precision by handling the length of the cut sheet for repairing the sheet as the calculation value in the control circuit for a taking-up machine. CONSTITUTION:An optical detector 10 measures the distance Y up to the surface of a taken-up roll paper 9 and measures the taken-up roll diameter D from each distance X, Y. The contact points 13 and 14 for distributing the partitioned values of the taken-up roll paper diameter value are set, and the detection values are memorized into the roll diameter memory circuits 15 and 16 through the contact points 13 and 14. Through this course, each taken-up roll paper diameter before and after the cut of the sheet is memorized into the both memory circuits 15 and 16, and the sheet length after the cut is calculated from the paper thickness obtained by a paper thickness setting device 18, in a sheet length calculating circuit 17. Then, the sheet length is input into a constant length control circuit 5, and the constant length control value is corrected. Therefore, the correct taken-up roll diameter D can be obtained directly even during the stop of the taking-up machine, and the constant control value of the length of the cut sheet can be corrected with high precision.

Title: Magnetic head
Inventor: NAITO KANICHI
IPC: G11B15/12
Filed: 1985-01-24
Abstract: PURPOSE:To preform excellent recording and reproduction by providing a switching conductor in a magnetic path for magnetic flux shorting provided between a magnetic gap and a coil part. CONSTITUTION:For example, when a recording signal is flowed to a magnetic head 1A in odd-numbered fields and to a magnetic head 1B in even-numbered fields, a DC current is applied to the switching conductor 8 in the operation of the magnetic head 1A and no DC current is applied to the switching conductor of 8 the magnetic head 1B. Consequently, even if recording signal magnetic flux leaks from the magnetic head 1A to the magnetic head 1B, it does not appear in the gap 3 of the magnetic head 1B as a crosstalk magnetic field through the magnetic flux shorting magnetic path 107 of the magnetic path. Further, this is used as a channel head by a multichannel magnetic head except a two-channel magnetic head. Consequently, crosstalk between adjacent channels is reduced and excellent recording and reproduction are realized.

IPC: G11B21/12
Filed: 1983-01-28
Abstract: PURPOSE:To prevent a medium from being damaged by providing a supporting device moving a side head so as to bring it into contact with the medium at almost zero speed while loading a head to mitigate a shock onto the medium at head loading. CONSTITUTION:In applying power to a solenoid 13, an armature 14 is absorbed to the solenoid 13, causing a slider 11B to be moved to the right in the figure. Then, a slider 11A linked by a rod 12 is moved downward and the side head 7 is also moved downward to attain the head loading state. The speed of the head 7 at the moment when the side head 7 and the medium 3 contact is decreased as follows: In taking the x coordinate of a point P as xp, the y coordinate at a point Q as yq, and the length of the rod 12 as l, then the relation of xp<2>+yq<2>= l<2>, i.e., d(yq)/dt=xp/yq.d(xp)/dt is obtained. Adjusting the position of the slider 11B and the solenoid 13 to attain head loading at xp 0, d(yq)/dt is reduced to nearly zero. Thus, the free fall descent speed of the side head 7 is nearly zero at the moment when the head is loaded.

Title: Fixing of permanent magnet field
Inventor: HISHIYAMA MASAHIKO
IPC: H02K1/17
Filed: 1979-02-02
Abstract: PURPOSE: To facilitate the workability eliminating adverse effect upon the permanent magnet due to welding heat by a method wherein a retaining plate is mounted across the sides of opposing pole pieces, and the permanent magnet is held by pinching between the yokes while the retaining plate and the magnetic poles are fillet- welded.  
     CONSTITUTION: A magnetic pole piece 1 is brought into contact with the tip of a permanent magnet 2 while a retaining plate 4 made of a non-magnetic metal is done so with both sides of magnetic poles 1 as opposed. Then, the surface 4a of the retaining plate 4 is pad welded with the surface 1a of the magnetic pole pieces so that the thermal reduction force generated during the cooling of the weld beads grasps the permanent magnet 2 between the magnetic pole pieces 1 and the yokes. With such an arrangement, the absence of welding for the permanent magnet 2 eliminates adverse effect due to welding heat. In addition, lack of the welding for the yokes enalbes the use of a cheap ductile cast iron for the material of the yokes.
