Title: Magnetic head
Inventor: YOSHIZAKI RIYUUICHIROU
IPC: G11B5/235
Filed: 1984-02-09
Abstract: PURPOSE:To prevent extension of an effective gap width due to mutual dispersion of ferrite and glass and deterioration of the ferrite due to heat treatment for glass welding by using the ferrite as magnetic core materials and packing a resin to form a magnetic gap part. CONSTITUTION:A polyester seam 4 for prescribing the gap width is interposed in the state, where it is led in from a sliding face 5, between faces 1a and 1a facing each other of core half bodies 1 and 1 which consist of the ferrite and are butted to constitute a magnetic core. An epoxy resin 6 where, for example, about 60% SiO2 is added as an fine inorganic powder for the purpose of enhancing wear resistance is packed between core half bodies 1 and 1 on the polyester seam 4, and core half bodies 1 and 1 are jointed and fixed with the resin 6 between them to form the magnetic gap part. Extension of the effective gap width is very small because the resin 6 and the ferrite of core half bodies 1 and 1 are hardly dispersed mutually dissimilarly to convertional constitution and the stronger magnetic gap part is formed because the resin 6 itself functions as an adhesive.

Title: Median strip and block for median strip
Inventor: MATSUDA SHIGERU
IPC: E01F15/08
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To prevent an accident from occurring by making the lower end of the side of a median strip extending along vehicle lanes a gentle slope that is joined flush to a road surface and has a face nearly parallel thereto and the upper part a slope getting steeper toward the top. SOLUTION: The lower end is made a gentle slope X1 that is joined flush to a road surface and has a face nearly parallel thereto and the upper part a slope X2 getting steeper gradually toward the top. The sides of the median strip 1 are curved into a circular arc state whose center is outside the median strip 1 and do not have a step, getting steeper gradually. If a vehicle runs onto the side of the median strip 1 by accident while running, its tire rises up the slope. However, as the slope gets steeper toward the top, the tire cannot go up higher. On the contrary, the tire comes down smoothly along the curve and return to its original natural condition before running onto it. Therefore, an accident can be prevented.

Abstract: PURPOSE: To maintain a good fluidized condition and to operate in a stable fluidized layer in a fluidized layer reactor by functionally measuring the differential pressure of flow rates between a flow rate at which reacting particle group start moving and a flow rate of fluid body which has finished operation.  
     CONSTITUTION: A detector container 71 is installed at medium-stage, lower internal wall of a fluidized layer reactor 1 and a detector container 72 at the upper stage of  the internal wall. Both containers 71, 72 are filled with detector particle group  whose fluidization initiating speed Umf is larger than that of reaction particle  group. Gas 10 which passes through the fluidized layer 12 is flowed into he detector  container 71. This causes differential pressure ΔPdR between the filled layer of the  detector particles 15. Produced gas 13 after operation is flowed into he detector  container 72. This causes defferential pressure ΔPd between the filled layer of  detector particles 15. The ratio of both differential pressure is measured functionally, and is used to control the amount of gas 10 and reaction particles 11 to be  supplied. In this manner, fluidized condition in the reactor is always maintained at  good condition.

The inner side of the secondary tile 2 is horizontal, while its outer side is diverged wider than the inner side of a primary tile 1. Combustion gas 9 flows parallel to and along the inner side of the secondary tile 2, where sprayed fuel gasifies and burns. Secondary air 10 is violently swirled with a secondary swirler in order to get the quantity of air necessary and enough for combustion. The secondary air 10 spreads outward so as to spread flame in order to shorten the flame length. The inner side of a tertiary tile 3 is divergent to the degree same as the outer side of the secondary tile 2 so as to prevent the secondary air 10 from separating from the inner side or the turbulence of air flow from occurring. Consequently, the combustion under low percentage of excess air and the shortening of flame length are possible.
