摘要： Disclosed is a method of drawing a metal wire to a specified diameter using a continuous dry drawing apparatus including a plurality of die units disposed in series, each of the die unit being composed of a dry lubricant unit for applying a dry lubricant on the surface of a metal wire and a die provided on the downstream side of the dry lubricant unit, the method comprising an intermediate coating process of forming a coating film on the surface of the metal wire for enhancing the picking-up of a dry lubricant for subsequent die-drawing, in at least one of the spaces between adjacent die units. With this method, seizure of the die is prevented and the drawing speed is significantly enhanced.

摘要： PURPOSE:To compensate for deficiency in heat generation due to the depth of a cut part and to prevent the occurrence of plucking, by a method wherein partial cutting of a metal surface is effected in a condition to heat a cutting edge. CONSTITUTION:At both sides 1a and 1b of the cut surface of a material 1 to be cut, a cut depth is shallow, and thereby an unsufficient amount of heat is generated, resulting in the occurrence of plucking. Heating of a cutting tool 3 compensates the portion, where plucking occurs, of the material 1 to be cut for deficiency in a heat generation amount of a part equivalent to that at a depth down to (t). Contact with the heating tool 3 provides temperature distribution as shown by a broken line, and prevents the occurrence of plucking. It is desirable that heating of the cutting edge of the tool is held at an arbitrary temperature in a range of 100-800 deg.C,. and a heating method is not limited.

摘要： PURPOSE:To obtain a stroke sensor which can be manufactured without consuming much labor and time and can highly accurately and highly sensibly make detection. CONSTITUTION:Signal sections 3 are formed at regular intervals in the axial direction around the outer periphery of a nonmagnetic rod member 1 and each signal section 3 is formed by plating an Fe layer in a groove cut into the member 1 to a fixed depth. When the signal sections 3 pass through detection coils 4A and 4B, the impedances of the coils 4A and 4B periodically change and the moving amount of the member 1 is detected from the periodical changes of the impedances. Since the signal sections 3 are formed by plating, the need of a welding process and another process for removing the thermal stress produced at the time of welding can be eliminated and, at the same time, the sections 3 can be formed with high accuracy. In addition, since the permeability variation is large, the moving amount of the member 1 can be detected with high sensitivity. Since the signal sections 3 can be formed on the surface of the rod member 1 in a solid and compact texture, the sliding characteristic of the rod member 1 is not deteriorated.

摘要： PURPOSE:To obtain magnetic scale material of excellent durability and high detecting accuracy with a boundary between a non-magnetic part and a magnetic part clearly being distinguished by forming recessed parts on the surface of the graduation formation predetermined part of a high Mn non-magnetic steel base material by machining, and coating the inside of the recessed parts with a magnetic material by plating. CONSTITUTION:The non-magnetic part of round bar raw material 1 made of high Mn non-magnetic steel is clearly partitioned from each magnetic part formed of a pure plated layer 3 in a groove 2 by the side walls of the grooves 2. Recessed parts each having the specified shape and depth are previously formed on the surface of the raw material 1 by machining, and inside each recessed part the material 1 is coated by plating or the like. The whole surface is then finished by machining to form a magnetic scale material. At the time of detecting this magnetic scale material by a magnetic sensor or the like, the non-magnetic part and the magnetic part are detected in the state of being clearly divided by the recessed part as a boundary so as to obtain the magnetic scale material of excellent responsiveness and high detecting accuracy.

摘要： PURPOSE:To improve the corrosion and heat resistances by forming the high-Mn non-magnetic steel of the prescribed composition where the strength is adjusted by the cold working at the prescribed temperature. CONSTITUTION:The high-Mn non-magnetic steel of austenitic structure having the composition consisting of, by weight, 0.03-0.4% C, 10-30% Mn, and further containing B-24% Cr, 0.02-10% Ni, 0.05-0.45% N, and 0.1-6% Mo as necessary is used. After the 0.2% proof load is adjusted to >=588N/mm , and the tensile strength is adjusted to 882-1569N/mm through the cold working respectively, the steel stock is formed to the ring chain while keeping the temperature of the steel stock in the temperature range of 200-950 deg.C. This constitution allows the use of the steel for a long time even when the steel is placed in the environment where the corrosion resistance or the heat resistance is required.

摘要： PURPOSE:To improve desired flaw detecting and selecting ability without decreasing flaw detecting accuracy using fluorescent magnetic powder, by turning an optical fiber probe in the opposite direction with respect to a material whose flaw is to be detected, and shortening the net flaw detecting time in the rotary scanning of the part of the flaw. CONSTITUTION:Ultraviolet rays from a light source are guided through a light source optical fiber 4 and concentratedly projected at a local part 1A' of the outer part of the flange of a flaw finding part 1A through a tip light emitting part 4A. The fluorescent light having a specified wavelength emitted from the local magnetic powder based on the projection of the ultraviolet rays is received through the field of view of an optical fiber probe 5. The light is guided through a receiving optical fiber 6 and transmitted into a photomultiplier 7. Photoelectric conversion is performed, and the signal is inputted into a process control device 9 through a connecting cable. Thus a specified signal processing is performed. In this way, desired flaw detecting and selecting ability can be improved without decreasing the flaw detecting accuracy using the fluorescent magnetic powder.

摘要： PURPOSE:To enable the lighting of a part intended to inspected flaws alone at a high intensity of illumination, by a method wherein ultraviolet rays condensed into a small section are transmitted with a condenser mirror through an optical fiber and scattered light from an end of the fiber is reflected with a cap mirror to irradiate in a specified direction. CONSTITUTION:Current is supplied to a mercury lamp 1 from a proper power source such as rectifier to emit ultraviolet rays. The ultraviolet rays thus emitted are condensed with as condenser mirror to one end 4a of a flexible optical fiber 4 to be transmitted with the optical fiber 4 after a visible light component is suppressed with a glass filter 2 and reaches the other end 4b thereof near an inspector section to irradiate a surface 6 to be inspected. Except for traveling forward, light caused as scattered light at the other end 4b of the optical fiber is reflected forward with a cap mirror 5, thereby achieving a higher brightness along with limited light range.
