Title: Container for standard liquid etc.
Inventor: TERAJIMA MASAAKI
IPC: G01N1/10
Filed: 1987-10-15
Abstract: PURPOSE:To prevent the use of a concentrated liquid by providing a liquid container with a member for preventing the insertion of a liquid removal instrument therein at the height of the liquid surface below a predetermined height from the inner surface of the container bottom. CONSTITUTION:A member 5 for preventing the insertion of a liquid removal instrument is placed in a liquid container 1 provided with an opening portion sealable with a lid 2 at the upper part thereof at a predetermined height from the inner surface of the bottom thereof in such manner that the removal of the liquid becomes difficult, as the liquid surface is lowered below that height. This preventive member 5 may be either a platelike or netlike material and a clearance between this member and the inner surface of wall in the liquid storing portion of the container is sufficiently large to allow the full flowing of the liquid. It is important that the material thereof be the type which does not affect the liquid composition. The preventive member is fixed at a height corresponding to that of the liquid in the minimum limit of the amount, with changes in the liquid concentration resulting from evaporation confined within a practically negligible limit. This method makes removal of the liquid impossible, when it is reduced to such an amount that changes in the liquid concentration due to the opening of the container poses a problem, thereby practically preventing the errors of analysis due to variations in the liquid concentration.

Abstract: PURPOSE:To check a sudden change in air-fuel ratio near change-over time for inputting throttle valve opening to control a shock due to acceleration and deceleration by correcting detected value read on a secondary detector on detected deviation between the primary and the secondary detector at said change-over time. CONSTITUTION:A throttle valve opening sensor is composed of the primary detector B for detecting in the area of a narrow valve opening and the secondary detector C for detecting in the area of a wide valve opening. At change- over time for inputting the valve opening, a computing means E for difference in detected values determines deviation between detected value read on said primary detector B and that read on said secondary detector C, and a correcting means F corrects the secondary detected value on said difference in said detected values. Thus a sudden change in the detected values near said change- over time can be checked for the prevention of the sudden change in air-fuel ratio.

Title: Method for oxidation-reduction reaction
Inventor: KAWAI TAKASHI
IPC: B01J19/00
Filed: 1992-09-30
Abstract: PURPOSE:To easily control, to shorten reaction time, to enable production in a flow system and to improve productivity by causing a raw material and an oxidizing agent or reducing agent to flow on one side of a separation membrane and on the opposite side of the membrane respectively. CONSTITUTION:A raw material 1 and an oxidizing agent or reducing agent 7 are transferred to a separation membrane module or separation membrane element 4 by a pump 2 and a pump 8 respectively. The raw material side and the oxidizing agent or reducing agent side are distinguished by a separation membrane 10, not causing the raw material to enter the oxidizing agent or reducing agent side. Since the membrane area per module or element 4 is large, the oxidizing agent or reducing agent is thoroughly dispersed and fed to uniformly execute oxidation-reduction reaction, allowing a product 5 to be obtained. Consequently it is not possible that an excess oxidizing agent or reducing agent not required for reaction is mixed to generate insufficiently dissolved bubbles in the raw material. In addition, the feed quantity of the oxidizing agent or reducing agent is controlled by a simple operation and oxidation-reduction reaction is executed in a flow system uniformly and in a short time.
