Title: Method of pulverizing ceramic powder
Inventor: KOHIKI HIDEAKI
IPC: H01F1/34
Filed: 1992-10-16
Abstract: PURPOSE:To make particle distribution of pulverized powder sharp by using a prescribed cylindrical pulverizing medium at the ratio of the outer diameter of the pulverizing medium to the height, in pulverizing ferrite, etc., by a rotary ball mill. CONSTITUTION:A cylindrical shape product with 0.8-1.2 at the ratio of the outer diameter to the height is used as the pulverizing medium. For example, the cylindrical pulverizing medium with 5.5mm outer diameter X5.5mm height is used. When this pulverizing medium is used, coarse particles larger than a certain particle size can be lessened compared with a case using a spherical pulverizing medium. For example, when Mn-Zn ferrite calcined powder is wet- pulverized, coarse particles larger than 3mum become less by using the cylindrical pulverizing medium and the particle distribution becomes sharp.

Filed: 1988-11-04
Abstract: PURPOSE:To detect terrestrial magnetism, etc., with high sensitivity by arranging a ground plane having an inside and outside diameters which are almost equal to those of a superconducting loop having a Josephson junction in a state where the ground plane is faced to the loop. CONSTITUTION:A superconducting loop 1 having a Josephson junction 1a is formed immediately above a ground plane 3 in a state where the loop 1 is faced to the plane 3. The loop 1 and plane 3 are formed so that they can have almost equal inside diameters and outside diameters. In addition, a notch 3a is formed in the plane 3 at the position corresponding to the junction 1a of the loop 1. Since both of the loop 1 and plane 3 prevent a magnetic field from entering inside by means of minus effects when such SQUID element is put in a magnetic field phix, the degree of concentration of magnetic fluxes to the edge section of the loop 1 can be relieved as compared with the case where the plane 3 does not exists. Therefore, terrestrial magnetism, etc., can be detected with high sensitivity.

IPC: F16D65/092
Filed: 1994-11-14
Abstract: PURPOSE: To obtain satisfactory performance in a wide temperature area by deforming a frictional member from a projected form to a recessed form by its temperature variation and vise versa, and causing deformation in a follow-up manner from a projected form to a recessed form by temperature variation of a base member or vise versa.

The frictional member 24A includes much lubricant and binder, and less magnesium oxide, showing a small frictional coefficient and satisfactory abrasion resistance. When the brake is operated frequently and the temperature of the disc rotor 12 is 350 deg.C or more, a back plate 22 is deformed from a projected to a recessed form due to difference of a thermal coefficients of steel plates 22A and 22B composing the back plate 22. The frictional member 24 is also recessed, while the disc rotor 12 is pressurized by means of upper and lower edge frictional members 24B. The frictional member 24B includes less lubricant and binder, and much metal fiber and magnesium oxide, showing a large frictional coefficient and feding resistance.

Title: Synchronization discrimination circuit
Inventor: IIZUKA NOBORU
IPC: H04J13/00
Filed: 1991-10-25
Abstract: PURPOSE:To detect the synchronizing step-out of the phase of a diffusion code for modulation without fail by variably setting the threshold value of the mutual correlation value between a diffusion code and a diffusion code for demodulation according to the power level of the modulation output to be obtained according to a code which is successively shifted to the value smaller than the maximum value. CONSTITUTION:A phase variable means 15 successively shifts the phase of a diffusion code A for modulation to a value whose correlation value between the code A and a diffusion code B for demodulation becomes smaller than the maximum value. Since the correlation between the phase-shifted codes A and B can not be taken, a diffusion modulation means 11 obtains the noise power level which is obtained as the modulation output. A threshold value variable means 17 variably sets the threshold value of a comparator means 13 according to the power level. Since the noise component has no correlation with the code A, the same level of noise component is superimposed to the primary modulated wave of the means 11 in a restoration state of the phase of the code A. Thus, the means 13 can detect the synchronizing step-out without fail by securing a constant noise margin even with large noise power.
