Title: Anisotropic conductive tape
Inventor: KASUGA KOJI
IPC: H01B5/16
Filed: 1992-12-28
Abstract: PURPOSE:To provide an anisotropic conductive tape used for connecting an LCD panel to a driver for driving it. CONSTITUTION:Both particles of conductive particles 3 and nonconductive particles 4 are mixed with a thermohardening bonding agent 2 to obtain an anisotropic conductive tape 1. When an LCD panel and a driver precharged TCP (TAB) are connected to each other by thermocompression by use of the anisotropic conductive tape, foams are produced between adjacent terminals, and even when particles come into contact with each other like a string of beads within the foams, at least nonconductive particles probably mixingly exist among those particles being in contact with each other like a string of beads, and 'short-circuiting between the adjacent terminals' can be prevented by the nonconductive particles. Also, by use of the anisotropic conductive tape, particularly thermocompression is applicable to such a narrow pitch between the adjacent terminals as about 0.1mm or less, and further repair work such as pressure rewelding is not required and also such an effect as an improvement in a throughput is produced.

Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To make a wheel movable on, not only a horizontal surface but a vertical surface and an overhung surface, by constituting a block by a plurality of permanent magnets, rotating the block, and moving the block rotated while switching it. SOLUTION: A wheel 2 and a bearing 4 of a block is rotated as a magnetic bonding wheel bearing 1 is rotated. Among the block 3 which is attracted to an iron surface 8 of a gas tank, one block 3 opposite to the direction of rotation must be separated from a metal surface for rotating the wheel. A rotary gear 6 integrally formed with an eccentric cam 5 set up in a rear side of the block 3 is turned by a gear 7 fixed to a car body. Since the eccentric cam 5 in this condition pulls one of the block 3 from behind, the block 3 is rotated with its bearing 4 serving as the center, to perform a transfer from a flat permanent magnet constituting the block 3 to a diagonally cut permanent magnet, and the block is made in adhesion to the iron surface 8 of the gas tank. This process is repeated, so that the vehicle body can be advanced forward by rotating the magnetic attraction type wheel.
