Title: Magnetic recording medium
Inventor: MORITA HARUYUKI
IPC: G11B5/712
Filed: 1983-02-07
Abstract: PURPOSE:To improve the chemical stability of a magnetic layer and at the same time to ensure recording over a wide frequency range from a short wavelength through a long wavelength, by forming a lamination type magnetic layer whose highest layer contains the ferromagnetic metallic nitride on a nonmagnetic substrate. CONSTITUTION:The nitride (containing nitride totally or only on the surface or the mixture of both) is obtained by adding Cr, Mn, etc. to a ferromagnetic metal only of Fe, Co and Ni or its alloy together with addition of a small amount of nonmetallic elements of B, C, Si, P, etc. The particles of said mixture are mixed with metallic magnetic particles within a range of (9:1)-(2:8) between the nitride and metallic particles in terms of wt%. Such a mixture is dispersed into a binder to obtain a magnetic layer. This magnetic layer is used to the highest place of a lamination magnetic layer formed on a substrate. The coercive force of the highest layer is set higher than the lower layers. The deterioration of oxidation is prevented for the lower layers since a metallic nitride magnetic matter has high oxidation resistance and high hardness. At the same time, the wear resistance of the magnetic layer is improved. The highest layer of the magnetic layer takes charge of recording with a short wavelength; while the lower layers take charge of recording with a long wavelength respectively. As a result, an excellent magnetic recording medium is obtained.

Title: Precoat filter element
Inventor: ASHIYOKU KUMAA BAANOTSUTO
IPC: B01D29/11
Filed: 1989-01-26
Abstract: PURPOSE: To maintain a precoat homogeneous over the entire length of the septum of a filter element during precoat treatment and to prolong the life of the precoat by controlling the distribution fluid, thereby lessening the corrosion of the precoat in the low part of the filter element. CONSTITUTION: The filter element 1 of the precoat type having a filter element chamber which holds the pressurized fluid and includes a fluid intake port 102 is provided with the septum 10 having a discharge space into which filtrate flows. A base part cap 30 is disposed below the septum 10 and an isolated pipe 40 is connected to the discharge space of the septum 10. The pipe 40 allows the filtrate to flow out of the septum 10 through the filter element chamber. A flow straightener 50 including meshes is arranged around the base cap 30 to allow the passage of the liquid through the flow passage between the intake port 102 and the septum 10. The distribution of the fluid is thus controlled and the corrosion of the precoat of the lower part of the filter element 1 is lessened, by which the even consumption of the precoat is assured and the life of the precoat is prolonged.

Title: Rotating speed detector in dc brushless motor
Inventor: ITOU NORIHIKO

Filed: 1982-02-05
Abstract: PURPOSE:To obtain a rotating speed detector havin good S/N ratio in a DC brushless motor by composing it of a rotary member of magnetic material coupled to a rotor magnet, a magnetic member and a detecting magnet. CONSTITUTION:A magnetic flux from a detecting magnet 9 passes through the path designated by broken lines, and is led as a rotating speed signal of a motor which is detected by a coil 8 in the variation in the magnetic reluctance due to  the variation in the relative positions between the tooth 4a of the peripheral  edge of a rotor yoke 4 and the teeth 7a, 7b of magnetic members 7A, 7B. On the  other hand, the magnetic flux from a rotor magnet 5 passes through the path designated by solid lines to cross the coil 8. Since the angular ranges of the  teeth 7a, 7b of the magnetic members 7A, 7B correspond to 2 poles of the rotor  magnet 5, the magnetic flux directions of the half magnetic fluxes crossing the  coil 8 become reverse to cancel each other. Accordingly, noise component based  on the magnetic flux from the magnet 5 is nt superposed on the rotating speed  signal, bus a rotating speed signal having good S/N can be led.
