Title: Coloring method for stainless steel
Inventor: TAKEUCHI TAKESHI
IPC: C23C22/77
Filed: 1979-03-20
Abstract: PURPOSE: To color uneven surface of stainless steel to a required tone of color at an excellent reproducibility, by determining a differential curve of change in potential difference with time between those at the surface of the stainless steel immersed in a coloring fluid and at the reference electrode, and by controlling the coloring according to the value determined previously in relation to the required color.  
     CONSTITUTION: In coloring stainless steel 3 by immersing it in a coloring fluid 1, the change (a) in difference with time between the surface potential of the steel 3 having uneven surface and the potential of a platinum reference electrode 2 is determined by means of the platinum reference electrode 2, a digital mV meter 4, a microcomputer 5, a D/A converter 6, and an analog recorder 7 etc. The differential curve (b) is determined by differentiating the change (a) with time with respect to the time. The point on the curve (b) at which coloring is initiated is considered to be the point C', where decreasing trend of the curve changes to increasing trend. When the potential difference changes from C' to a value equal to that previously determined in relation to the required tone of color, the steel 3 is taken out from the coloring fluid 1, thereby controlling the color tone at a required value.

IPC: G11B5/39
Filed: 1980-03-13
Abstract: PURPOSE:To suppress the heat radiation and ensure a simple control of the demagnetizing current, by using one of a paired electric resistance elements for magnetic detection for a monitor of the magnetic flux density of a magnetic substance and at the same time forming the demagnetizing current to a coil into a form of the pulse train. CONSTITUTION:The A17 of a paired magnetic resistance elements 16 of a magnetic detector 15 is connected to the stabilized DC voltage VC and the input of an amplifier 18. The terminal connected to the amplifier 18 is also connected to the NC terminal 20 of a switch 19. The coil 27 wound round the magnetic substance 26 is connected to the current switch 28, and thus the current flows in the directions of IM and IE during a magnetization and demagnetization respectively. The demagnetization signal control circuit 29 generates both the demagnetization gate signal 30 and the current synchronous pulse 31 by the demagnetization signal. Thus the signal 30 is applied to the current control circuit 32, the switch 28 and the switch 19; while the pulse 31 is applied to the circuit 32 and the voltage comparator 25 respectively. In such way, a demagnetization is ensured by the demagnetizing current pulse 33 that increases gradually with the time synchronous with the pulse 31.

Abstract: PURPOSE:To prevent lowering of a pulsation absorbing action owing to an influence exercised by a gap between the plate-form members of a helical pipe by a method wherein the gap is produced owing to a change in an inside diameter occasioned by caulking of a metallic pipe. CONSTITUTION:A taper part 13b the outside diameter of which is reduced in the direction of an end face is formed at the outer periphery of a metallic pipe 13. The metallic pipe 13 is pressed by means of a caulking tool having a press surface, paralleling the metallic pipe 13, from the outside of the taper part 13b to caulk the helical pipe 20. An inner peripheral taper part wherein an inside diameter is increased in the direction of an end face is formed on the inner peripheral side. Since the helical pipe 20 is fixed by means of the inner peripheral taper part, the change of an outside diameter is slowly produced at the helical pipe 20, and a gap is prevented from being formed between the plate-form members 20a and 2Ob of the helical pipe 20.

Abstract: PURPOSE:To reduce the differences in the rates of thermal expansion coefficients occuring in the temperature differences in the thickness direction of the staves by dividing the stave body to two or more pieces, spacing the respective divided portions and connecting the respective divided portions by the cooling pipes burined in the stave body. CONSTITUTION:A stave body 1 is bisected in the vertical direction and the respective divided portions 1a, 1b are spaced to above and below. These are mutually coupled and integrated by the cooling pipes buried in the stave body 1. The cooling pipes 2 are maintained in the state non-welded to the stave body 1 and the respective portions 1a, 1b are restrained of relative displacement with respect to the cooling pipes by the bent ends 2a of the cooling pipes 2. In this way, the stave is fixed by passing the bent ends 2a into the openings 3a provided to a sheet iron shell 3 and airtightly welding these ends 2a to the sheet iron shell 3 by way of flat type fixing plates 4. According to this method, the excessive stress action upon the sheet iron shell occuring in the thermal expansion of the stave body is prevented and the durability of the stave and sheet iron sheel is enhanced.
