摘要： PROBLEM TO BE SOLVED: To improve the dispersion characteristic of magnetic pigment by allowing one or more kinds of aralkyl phosphoric acid to be adsorbed on the surface of non- magnetic supporting material having a dispersion film in a polymer binder of magnetic pigment suitable for the use of the magnetic recording medium, etc. SOLUTION: A magnetic recording medium contains magnetic pigment which adsorbs on its surface one or more kinds of aralkyl phosphoric acids represented by a specific chemical formula (where Ar denotes aryl group and R denotes aliphatic group with 1-6 carbon atoms and (n) is an integer not smaller than one). The magnetic pigment is mixed with the compound represented by the formula with a solvent enough to generate a smooth magnetic paste, it is diluted with a polymer binder and solvent to be formed into solid content in percentage to be capable of further processing, (e.g. sand mill) the dispersion is processed to be applied on the substrate. The aralkyl phosphoric acid modifier gives a further imposed characteristic than in the case of phenyl phosphoric agent as the modifier, distributed material by the sand mill, etc., and a process for forming a film made of the obtained distributed material on a base material of the magnetic recording medium. The surface reforming compound of aralkyl phosphoric acid gives an improved characteristic to the magnetic pigment particle in comparison with a conventional one using phenyl phosphoric acid.

摘要： PROBLEM TO BE SOLVED: To provide a connector which brings corresponding conductors in pressure contact simultaneously with a multicore main line cable and a branch cable disposed vertically in a superimposed manner on each other. SOLUTION: Connecting pieces 12 of a connector 10 are each equipped with a first conduction contact part 18 having a first slit 16 into which a main line is press-fitted and a second conduction contact part 22 having a second slit 20 into which a branch line is press-fitted. The first slit 16 and the second slit 20 extend rectilinearly and parallel to each other in the longitudinal direction of the connecting pieces 12. The first conduction contact part 18 and the second conduction contact part 22 are disposed apart from each other so that the main line press-fitted into the first slit 16 and the branch line press-fitted into the second slit 20 can be positioned in such a manner that they are substantially aligned in the extension direction of these slits 16, 20. A wire inlet end 24 of the first slit 16 and a wire inlet end 26 of the second slit 20 are formed in positions where the direction that press-fits the main line into the first slit 16 becomes equal to the direction that press-fits the branch line into the second slit 20.

摘要： PROBLEM TO BE SOLVED: To provide a fixture which enables a dental orthodontist to easily mount a dental orthodontic appliance to the patient's teeth. SOLUTION: The dental orthodontic fixture 20 for connecting the dental orthodontic appliance 36 to a bow-shaped wire 46 includes a slender wire 22 which extends in parallel with this bow-shaped wire 46. This wire 22 is fixed to a bendable connector 24 having a passage 26 to accept the wire. The wall part 28 enclosing the passage 26 is deformable in the direction toward the passage 26 so that the fixture 20 is made non-rotatably connectable to the bow-shaped wire 46. A pin having a deviating part is connected to the appliance 36 in the position apart from the fixture 20 to increase the play of the freedom of the appliance 36 when the patient's jaw is opened.

摘要： PROBLEM TO BE SOLVED: To provide a method of production of magnetic alloy grains composed essentially of iron, having high coercive force and great saturation magnetization and minimal in deterioration in these characteristics with the lapse of time. SOLUTION: After precursor grains, composed of hydrated iron oxide or iron oxide grains containing cobalt(Co) by 15-45 atomic % based on Fe, are reduced, first slow oxidation is carried out at 20-100 deg.C under an oxygen- containing gaseous atmosphere. Then, after annealing treatment at 120-450 deg.C under an inert-gas atmosphere, second slow oxidation is performed under an oxygen-containing gaseous atmosphere.

摘要： PROBLEM TO BE SOLVED: To provide a plastic core for an adhesive tape to keep the peel strength of the innermost peripheral adhesive tape of a roll at a comparatively low value even when a roll-form adhesive tape is mounted on an adherend by using an automatic machine, prevent the adhesive tape from being mounted on the adherend in a state that the adhesive tape is unnecessarily stretched, and improve deformation resistance during long term preservation at a high temperature in a state that the adhesive tape is wound. SOLUTION: The core of a hollow cylinder body formed of plastic is used for forming a laminate of an adhesive tape by winding the adhesive tape therearound. Plastic containing polyorefin having characteristics D1 having density of 0.88-0.94g/cm and characteristics Ml having a modulus of bending elasticity of 600-10,000kg/cm is use as the core of the hollow cylinder.
