Patent JP-S59162907-A (JP)
Title: Electrodyalitic apparatus
Inventor: KANENOBU FUMIHIKO
IPC: B01D61/54
Filed: 1983-03-07
Abstract: PURPOSE:To enhance dialytic efficiency by preventing the mixing of a desalting treated liquid and an untreated liquid, by providing a baffle plate in the desalted liquid tank of an electrodyalytic apparatus to allow said tank to function as a layer forming type tank. CONSTITUTION:A baffle plate 12 is attached to the interior of the desalted liquid tank 2 in a conventional electrodyalytic apparatus to convert said tank to a liquid layer forming type tank 11. When the treated liquid returning from a dialytic tank 1 through an arranged pipe 6 enters the tank 11, it is flowed to the tank outlet from the tank inlet part while rectified and, therefore, recirculated and supplied to the dialytic tank 1 by a desalted liquid recirculating pump 4 without being mixed with the untreated liquid remaining in the lower side of the tank 1. The amount to be used of electric power is prevented from increasing by suppressing the increase of the electric resistance of the liquid in the dialytic tank caused by the mixing of the treated liquid and the untreated liquid to enhance dialytic efficiency.

Title: Mold release agent for reaction injection molding
Inventor: TAKAHASHI TOSHITAKA
IPC: B29L31/30
Filed: 1989-02-15
Abstract: PURPOSE:To effectively lower the generation of sink mark without deteriorating production efficiency of reaction injection molding of a urethane-urea system by incorporating acylosiloxane and silane having silanol group in the terminal. CONSTITUTION:A mold release agent for reaction injection molding which incorporates acrylosiloxane and silane having silanol group in the terminal produces organic acid as shown in a formula (1) by heat which is caused by the temp. of a heated mold and reaction at a time for reaction injection molding. The produced organic acid retards transition of a proton to isocyanate group and deteriorates reaction velocity in a urethane-urea reaction system. Therefore, reaction velocity in the vicinity of the inner face of a mold to which the external mold release agent is applied is deteriorated. As a result, the curing velocity of only resin in the vicinity of the inner face of the mold is lowered. Therefore the cured resin in the vicinity of the inner face of the mold is prevented from receiving tractive force by uncured resin separated from the inner face of the mold. Generation of sink mark can be greatly lowered.

Abstract: PURPOSE:To prevent aggregation of titanium oxide in application or in immersion and form a uniform impregnated layer, by using both a liquid composition containing titanium oxide particles and a liquid composition containing aspartic acid or an asparate (ASP for short) but not titanium oxide. CONSTITUTION:A liquid composition containing titanium oxide particles but not ASP is applied to or immersed in a porous liquid developing layer to form a layer. Then a liquid composition which contains ASP but not titanium oxide particles is used adjacently or through another layer to form another layer at the remote side from the face of the liquid developing layer to which a test specimen solution is fed. This developing layer is formed on a substrate such as polyethylene terephthalate polystyrene, etc., and may be combined with a reagent layer, an adhesive layer, a filtration layer, a water absorption layer, an undercoating layer, etc., to give a multi-layer. Since the application or immersion of ASP and titanium oxide is carried out separately, an analytical element having uniform performance can be formed.
