Title: Production of ferromagnetic iron powder
Inventor: OKAI MICHIJI
IPC: H01F1/11
Filed: 1985-02-20
Abstract: PURPOSE:To increase the dispersion properties and the orientative properties or the like in a magnetic coat of the magnetic recording medium in case of immersing the ferromagnetic iron powder in an organic solvent and oxidizing the surface of the powder to produce the stable ferromagnetic iron powder by washing the powder with an organic solvent after the oxidation. CONSTITUTION:The ferromagnetic iron powder is produced by such a method that the hydrated iron oxide is dehydrated, calcined and reduced and thereafter the obtained ferromagnetic iron powder is immersed into an organic solvent such as benzene and toluene to prevent the spontaneous ignition or the like and the surface is slowly oxidized to stabilize a gas contg. oxygen. The aimed ferromagnetic iron powder is obtained by washing it successively with the organic solvent and removing the oxidized product (e.g. benzoic acid and cresol) of the organic solvent adhered on the surface of the ferromagnetic powder. This ferromagnetic iron powder is preferably used as the magnetic material of the magnetic recording medium for the high-density recording.

Filed: 1981-03-05
Abstract: PURPOSE:To facilitate the control of a disc device, by lowering a recording density of a data format section required for comparison operation with a CPU, that is, the recording density other than pure data. CONSTITUTION:Synchronizing signal data of 46 and 47 are recorded just before and after a pure data region 42 are recorded at a sector format (b) in comparison with (a) of a conventional example.

The valve member 54 comprises an annular turbine unit which is rotated by fluid flow through tangentially-directed passages 50 and thus interrupts the flow to units of the first group of outlets 44 as a flat plate portion 56 of the valve member moves over surface 42 containing outlets 44. The second flow passage is formed by channels 48, which bypass the valve member 54, and grooves 34 formed in lower housing 20, which are sealed to form orifices by a washer 36 fittting inside housing 20. Water may be directed through these two passages and through a third passage, which passes through the centre of the valve member without substantially affecting its rate of rotation, by a flow-directing plate 62 which has arcuate openings corresponding with the three flow passages. Flow through the passages is controlled by an annular shutter plate 84, moved by the user of the device by means of a control ring 112 and a gear mechanism, and which has blades for closing the openings allowing continuous flow alone, a mixture of continuous and pulsating flow or pulsating flow alone. Reference has been directed by the comptroller to Specification 1430123.

Title: Low-tension two-split winding transformer
Inventor: FUJIMURA NOBUTERU
IPC: H01F29/02
Filed: 1981-03-06
Abstract: PURPOSE:To miniaturize the whole, and to reduce man-hour and the material cost by minimizing an insulating distance between the upper end section of a high-tension coil and the upper yoke of a core and reducing external thrust in the axial direction. CONSTITUTION:Insulation grades at the neutral point sides can be lowered in the high-tension coils under graded insulation because the high-tension coils 41, 42 are distributed in the up-and-down direction from the center of a coil stack and wound and the upper and lower ends are used as the neutral point sides. Accordingly, the insulating distances S3, S4 among the upper and lower ends of the high-tension coils and the upper and lower yokes 21, 22 of the core can be equalized to the insulating distances is conventional devices, and the insulating distance S3 can be minimized. Since tap coil sections 61, 62 are formed at the upper and lower ends of the high-tension coils, the distribution of ampere-turns of the high-tension coils is symmetrized up and down even when the ampere- turns of a tap section change according to the position of a tap, and mechanical power in the axial direction working to the low-tension and high-tension coils is minimized even to excessive currents in the case of the short circuit of the transformer.
