Title: Manufacture of dust core
Inventor: MURAI KENICHI
IPC: H01F41/02
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To improve permeability and high-frequency characteristics by extruding and molding the admixture of flat or needle-shaped metal powder and binder so as cause the powder alignment direction is parallel to that of the magnetic path. SOLUTION: In a method of manufacturing a dust core, ingots of Fe-Al-Si alloy formed through vacuum melting are roughly ground by a disc mill to powder of 100 μm or smaller, and further ground by a wet ball mill to process into a flat powder having an average diameter of 40 μm, average thickness of 2 μm, and an aspect ratio of 20. Then, the flat powder, silicone resin and stearic acid are kneaded with a weight ratio of 93:6:1 by a pressurized kneader to form a raw powder material for molding, which is then pelletized. The pelletized material is worked to form a plate-shaped molded body by an extruding molder at 200 deg.C. The molded body is heated at 120 deg.C, and inserted into a cylinder of 30 mm diameter.  Then, a 20 mm-diameter center core in which an ultrasonic vibrating element is built into is inserted and heated to make it mutually adhere to each edge of the plate by fusing. Then, the resultant body is cut to form cores.

Title: Hydraulic control valve
Inventor: KADOTA SHINKICHI
IPC: B60T8/26
Filed: 1980-02-19
Abstract: PURPOSE: To raise the operational braking point of a control valve so that a braking force may be secured even when one system develops a trouble by increasing a force applied to a control piston at the time of said trouble.  
     CONSTITUTION: A braking pressure applied to a rear wheel is introduced into a valve through an inlet 13, subsequently decompressed in a control piston 1 and then transmitted to a rear brake through an outlet 14. Although a braking pressure in a system not subjected to decompression is introduced from an inlet 15 to an outlet 16, this pressure pushes a cup 6 and a retainer 7 and further presses both a spring seat 9 and a spring 11 so that they do not come in touch with the control piston 1. In case something goes wrong with the system not subjected to decompression, both the cup 6 and the retainer 7 are not pushed. As a result, a spring 12 and the spring 11 work on the control piston 1 together, thereby raising the operational braking point of the control valve.

Abstract: PROBLEM TO BE SOLVED: To easily evaluate the degree of the fatigue damage of the metallic material of the bainite structure by using the electron back side reflection analysis (EBSP) in the measurement of the azimuth difference between cells. SOLUTION: The azimuth difference between cells is measured by the electron back side reflection analysis method (EBSP) using a test piece which is sampled from a part to be measured and polished, and the mapping indication thereof is performed by the prescribed angle, and the histogram of the distribution of the azimuth difference by the prescribed angular step is prepared. The test piece is corroded, and the critical angle is determined from the observation results of the grain boundary by the optical microscope, and the azimuth difference to indicate the grain boundary identical or approximately close thereto, and the angular mean value at the azimuth difference below the critical angle is obtained from the formula of the histogram on the assumption that the azimuth difference of the grain boundary at the angle smaller than the critical angle is generated by the fatigue damage.  The degree of the fatigue damage is evaluated using the thus-obtained mean intergranular angle. For this purpose, it is necessary to obtain the relationship between the known degree of the fatigue damage and the mean intergranular angle for the same material.

Abstract: PURPOSE:To display a picture with a wide dynamic range from a close part to a distant part by reducing an obvious side lobe in the close part of a probe and decreasing side lobe artifact. CONSTITUTION:The transmission pulse of an n-channel generated in a pulse generation circuit 1 is inputted to a transmission beam former 2.
