摘要:
The present invention provides an information display panel capable of maintaining an excellent image property even after repeated rewrite, and particles for display media used therefor. The information display panel, in which at least one kind of display media including a charged particle for display media are sealed in a space between substrates at least one of which is transparent, for displaying an image by application of electrostatic force to the display media by means of an electronic field forming means, uses the particle for display media comprised of a mother particle, child particles and fine particles. The child particles, having a molecular structure of three-dimensional crosslinked structure and a particle diameter smaller than that of the mother particle which has no molecular structure of three-dimensional crosslinked structure, are embedded in a surface of the mother particle. It thereby hardens the surface of the mother particle. Then, the fine particles having the particle diameter smaller than that of the child particles are attached to the mother particle having the child particles embedded therein, it is thus possible to prevent the fine particles from being buried in the mother particles.

There is provided an apparatus for measuring forces acted upon a tire in which a radial force and a peripheral force acting to the tire, which are required for the high precision measurement of a friction coefficient on a road surface, are simply measured in a high precision by detecting a magnetic field formed by a magnet fixed to a tread portion of the tire by a magnetic sensor fixed to a rim and measuring the forces acting to the tire from a variant pattern of a magnetic flux density detected un the rotation of the tire and without influencing upon the balance of the tire, which contributes to the high precision measurement of the friction coefficient on the road surface.

Methods and devices for measuring elongation, wear, and internal temperature of a conveyor belt to catch signs of conveyor belt failure such as breakage by detecting a magnetic field from a magnetic body by using a magnesium sensor, as well as a rubber magnet sheet as a magnetic body and a method of producing the sheet, the rubber magnet sheet being able to be used while it is embedded in the conveyor belt. To measure elongation of a running conveyor belt (11), a magnetic field of a magnetic body (2) embedded in the belt (11) is detected by a magnetism sensor (3) fixed to the earth, and elongation of the belt (11) is calculated from temporal variation of the detected magnetic field.

A seismic isolation apparatus features damping characteristics equivalent to or better than prior art, without burdening the environment. In this seismic isolation apparatus, a cylindrical cavity portion is formed at the middle of an outer side laminated body, which has a form in which respective pluralities of resiliently deformable rubber rings and metal rings for maintaining rigidity are alternately laminated. A helically formed coil spring is disposed in this cavity portion so as to be snugly fitted. An inner side laminated body, which has a form in which respective pluralities of resiliently deformable rubber plates and metal plates for maintaining rigidity are alternately laminated, is disposed at an inner peripheral side of the coil spring.

A change of magnetic characteristics of a magnetic circuit constituting body or a composite magnet arranged in a necessary portion of a tire is detected by a magnetic sensor detecting a magnetic field leaked from the magnetic circuit constituting body or a magnetic filed from the composite magnet, while a temperature in the necessary portion of the tire is directly measured or a degree of heat deterioration is directly measured by using a tire temperature sensor or a tire heat deterioration detection sensor constructed so as of change the magnetic characteristics of the magnetic circuit constituting body or the composite magnet dependent on the temperature or the degree of heat deterioration in the necessary portion of the tire, whereby it is possible to attain an early identification of the abnormality on the possibility bringing about the troubles of the tire. Also, there is provided a tire temperature sensor or a tire heat deterioration detection sensor causing no fear of the early battery drain.
