Title: Reducing method of dissolved oxygen in tank
Inventor: GOTOU TETSUYA
IPC: B01D19/00
Filed: 1983-07-28
Abstract: PURPOSE:To reduce the dissolved oxygen within a short period of about two days by injecting continuously nitrogen from a drain line provided at the bottom part of a large-sized tank opened to the atmosphere. CONSTITUTION:A hose 4 of a nitrogen tank 5 is connected to drain lines 11 and 12 provided at the bottom part of a condensate tank 3 opened to the atmosphere. About 150m<3> of water is contained in the tank 3. Valves 1 and 2 of the drain lines 11 and 12 are opened, and nitrogen is injected continuously into the tank 3. The rate is regulated to about 100l/h as liquefied nitrogen. The dissolved oxygen is released by the bubbling effect of the nitrogen injected from the bottom of the tank 3, and the water quality such as dissolved oxygen, etc. is made uniform because the water in the tank 3 is agitated by the bubbling. Since the vapor phase part at the upper part of the tank 3 is covered with nitrogen, the oxygen to be dissolved is eliminated. The concn. of the dissolved oxygen is decreased to about 0.01ppm.

Title: Edge-section lighting liquid-crystal display unit
Inventor: JIEI DEIBITSUDO MAAJIERAMU
IPC: G02F1/1333
Filed: 1990-05-25
Abstract: PURPOSE: To increase contrast in a liquid crystal display panel by illuminating the display panel through its edge part. CONSTITUTION: The illumination of the edge part of the liquid crystal display panel is used. In this edge illumination display. The quantity of scattered light at an electric field array and on segments 24 and 26 is small and the on- segments 24 and 26 effectively appears to be transparent. However, an off- segment 22 scatters light and appears to be shining as normal. As a black surface provided behind the panel 12 absorbs peripheral light, the on-segments 24 and 26 look black. Thereby the edge illuminated display can obtain contrast larger than normal background illumination in an intense peripheral light.

Title: Method and equipment for moving molecule by application of electric field
Inventor: DEIBITSUDO ESU SOON
IPC: G03F7/00
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To separate a mixture of charged particle by applying a plurality of different fields to a medium and migrating a charged particle through the medium under accurate control. SOLUTION: A trench 2 is made in a card 1 of appropriate size and filled with a medium 3, e.g. a buffer, and a plurality of electrodes 4-9 are plated to the card 1. A bias or a voltage is applied simultaneously or sequentially to the electrodes 4-9. Since various voltages are applied to a specific electrode, the capability for separating molecules migrating through a medium by an extremely accurate method is enhanced significantly and various types of molecules can be separated and analyzed to a level exceeding that of prior art. Since the substrate of card 1 is made of hard polymer, the card itself has no surface charge nor the trench 2 has any charge and thus a polymer coating is generally required in order to suppress electroosmsis.  Since the problem of high performance electrophoretic technology employing a glass capillary tube, i.e., electroosmsis, is eliminated, charged particles of protein are not absorbed.

Abstract: PURPOSE: To automatically and efficiently remove a base holder protecting the end of a base film wound around a core, by locating a base holder removal claw and a support rod for the removed base holder on a moving object which performs a reciprocating movement.  
     CONSTITUTION: A moving object 5 moves to the left resulting from the running of a chain 6, the moving object 5 stops moving when the end of the object 5 reaches a base holder H of a cassette K. A cylinder 14 is then functioned, claws 12 and 11 being hooked at the edge of the holder H as a result of the claws turning inward via links 16W18. The moving object 5 is then moved to the right resulting from the reverse rotation of a motor 1. The holder H is pulled off of a core of a base film B thereupon, the holder H being transferred onto a supporting rod 21 as a result of an inserting core hole in the core coinciding with the supporting rod 21. Afterwards, the holder H of the subsequent cassette reel K carried by a truck T is removed in the manner described above, the holder H being inserted in order onto the supporting rod 21.
