Title: Rubber crawler
Inventor: SAKAMOTO TADASHI
IPC: B62D55/253
Filed: 1999-10-14
Abstract: PROBLEM TO BE SOLVED: To provide a rubber crawler preventing rubber flow at a superposition connecting portion of a reinforcing cord, and improving durability by preventing flipping up of the superposition connecting portion. SOLUTION: In the rubber crawler 1 wherein a reinforcing cord line 3 longitudinally buried in the rubber crawler 1 of an endless belt has superposition connecting portions 3A, 3B, a cover element 4 covering a grounding outer peripheral side (3B) tip end 3C of the superposition connecting portions, and having width W4 larger than driving width W1 of the reinforcing cord line 3 is arranged. Flipping up of the grounding outer peripheral side tip end 3C of the reinforcing cord 3 is effectively prevented to suppress the occurrence of crack in a rubber crawler body portion, and even when the grounding outer peripheral side tip end 3C is disposed at a part where rubber is voluminous facing to a grounding lug 6, rubber flow on a grounding surface side at the time of vulcanizing the rubber crawler 1 is effectively prevented to dissolve the occurrence of scattering in the tip end of the reinforcing cord 3, so that tension received by each composing cord is made to be uniform to eliminate the fear of cord breakage.

Title: Method for spatially and selectively increasing refractive index of planar optical eaveguide and glass
Inventor: WEBER DIETER
IPC: G02B6/132
Filed: 1999-10-14
Abstract: PROBLEM TO BE SOLVED: To provide a method for raising the refractive index of glass, particularly of a planar waveguide, without subjecting it to a treatment for raising the photosensitivity. SOLUTION: This method does not perform a treatment for raising the photosensitivity in order to spatially and selectively raise the refractive index of a glass layer GS produced by depositing initial glass products of hydrolysis on a base by flame deposition and sintering the initial glass products thereafter. Instead, heat is supplied to the part of the glass where the refractive index should be raised. As a result, the density of the glass sintered increases, followed by an increase in refractive index. The area thus processed has the same chemical composition as an untreated area.

Abstract: PURPOSE:To manufacture a thin sheet-like magnetic powder-mixed molded body with strong attraction force by a method wherein rectangular plate-, bar- or wire-like magnetic particles are mixed and distributed in a molded body under the state that the posture of each particle is controlled. CONSTITUTION:Molding body material A such a resin or the like is mixed with rectangular plate-, bar- or wire-like paramagnetic or ferromagnetic particles B, kneaded C and molded D under heat with a molder. In the resultant molded body 1, for the heating and temperature rise E of the magnetic particle 3, the electromagnetically induced current generated with an electromagnetic induction heater 2 is passed through the magnetic particles 3 in the molded body 1. At this time, the heating and temperature rise are controlled so as to keep the temperature of the particle below its Curie point or temperature, at which the magnetic property of the magnetic particle 3 is lost. The heating and temperature rise E of the magnetic particle 3 softens and melts the ambient molded body material 4. Simultaneously with or just after the softening and melting of the material 4, the material 4 is passed through a magnetizing device 5 in order to magnetize F the particles 3 by giving magnetic field or to orientate the particle by the magnetic force of the magnetizing device 5 so as to make the direction of the magnetic particle aligne in the direction of the line of magnetic force. Thus, the positive pole and the negative pole clearly appear in the molded body, resulting in making the attraction force more stronger.
