Title: Method and device for processing magnetizable particle in assay, using magnetism separating technique
Inventor: BUSHNELL STEVEN E
IPC: G01N33/543
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To clean efficiently a magnetizable particle during separating and cleaning by using a soft magnetized insert instead of a separated magnet. SOLUTION: Because a soft magnetized insert 20 like low-carbon steel shortens or minimizes gradient of magnetic field on a position (H), or a resuspension cleaning position, and trimming of a magnet array 16 on positions G, I reduces chance for magnetic field to reach the resuspension position H from a same position, a single magnetizable particle zone on the position H is not divided into two zone, contrary to traditional technology. On a position M a trimed magnet 27 is set, and this makes the zone of collecting magnetizable particles more narrow. When a smaller magnet 28 which is a focusing magnet is used on a position N, a magnetizable particle is collected within a smaller area, and reagents are dispersed, a small solid-phase target is provided on a position P for the more efficient resuspension.

Title: Method for measuring cracking state of bedrock
Inventor: YAMAZAKI SHIGERU
IPC: G01H17/00
Filed: 1980-09-03
Abstract: PURPOSE:To measure the state of cracking by detecting the amplitude attenuation rate of the elastic waves in the part of bedrock to be measured. CONSTITUTION:First, a transmission vibration 1 and a reception vibrator 2 are pressed by load P, and elastic waves are applied to the vibrator 1 by a pulse generator 3, thence the amplitude A0 of the vibrator 2 is measured. Next, a part 4 of prescribed bedrock is provided between the vibrator 1 and the vibrator 2, and the amplitude A1 of the vibrator is similarly measured. Next, the difference A between the A0 and the A1 is determined, and the amplitude attenuation rate A of elastic waves is detected, whereby the state of cracking is judged. If the cracking is large, the rate A increases and if small, it decreases and therefore, the cracking state of said bedrock is judged if the amplitude attenuation rate of the elastic waves is measured.

Title: Liquid crystal display device

IPC: G09F9/30
Filed: 1980-09-04
Abstract: PURPOSE:To secure a conduction performance, to work plural sheets simultaneously, and to make the gap between upper and lower electrode plates uniform, by using an electrically conductive plastic having an elastic property, as a conduction material placed between the upper and lower electrodes. CONSTITUTION:A pulverulent body consisting of silver and carbon is used as an electrically conductive filler 201, urethane or silicone resin which expands in case of urethane or silicone resin which expands in case of thermosetting is used as a binder 202, and they are adjusted to the paste-like state having 200-300ps viscosity by use of solvent 203 such as xylene. A sealding material is thermally press-fixed, and an electrically conductive material is hardened simultaneously, and when it is hardened, urethane or silicone matrix is hardened while expanding, but since it is elastic, it is capable of sufficiently following an expanse between the upper and lower electrodes, which is caused by warping of glass or an ununiform load, after load has been removed. Also, as compared to a sealing material, it is soft and apt to be deformed, therefore, it does not exert influence on uniformity of a gap between the substrates.
