Title: Granular agricultural chemical readily disintegrable and diffusible in water
Inventor: SHIMIZU HIROMICHI
IPC: A01N25/12
Filed: 1983-11-08
Abstract: PURPOSE:To provide a granular agricultural chemical for the application to the surface of a paddy field, and disintegrable and diffusible even in water having high hardness, by granulating a mixture of a clay carrier and an active pesticidal component containing a condensed phosphoric acid salt and a chelating compound of a polyaminocarboxylic acid. CONSTITUTION:The objective derivative contains (A) a chelating compound of a polyaminocarboxylic acid or its salt, e.g. ethylenediamine-tetraacetic acid, nitrilotriacetic acid, etc., their alkali or alkaline earth metal salts, etc. and (B) a condensed phosphoric acid salt such as sodium tripolyphosphate, sodium tetrapolyphosphate, etc. The ratio of the component A to the component B is 20- 60% to 80-40%. The practical amount of the above additive is 1-3% of the clay carrier. Although the additive can be used in the form of powder, however, it is preferable to add the polyaminocarboxylic acid slowly to an aqueous solution of the condensed phosphoric acid salt, stir the mixture, and if the mixture is turbid, adjust the pH of the mixture to 6.5-8 with an acid or alkali to obtain a transparent solution. The solution is added to the derivative at an arbitrary stage of the granulation process.

Title: Method for reducing volume of high-performance air filter by incineration
Inventor: OSHITARI YOSHIMI
IPC: B09B3/00
Filed: 1981-12-28
Abstract: PURPOSE:To reduce the volume of a filter by incineration, by using combustible fibers instead of glass fibers used for holding the strength of filter paper of a high-performance air filter. CONSTITUTION:High-performance filter paper used for an air filter used in factories, etc. which handle radioactive materials, is constituted of fine glass fibers having the level of 20-50% by weight and 0.3-0.15mu diameter and of large glass fibers having the level of 50-80% by weight and 0.5mu and 1-10mu diameter. Among these fibers, the large-diameter glass fibers are used for holding the strength, but chemical fibers or natural fibers can be used instead of the glass fibers when the diameter is >=1mu, then such combustible fibers having >=1mu diameter are used. Thus the volume of radioactive waste is remarkably reduced because the weight of residuum of filter paper manufactured in such manner, is reduced after incineration treatment.

Abstract: PROBLEM TO BE SOLVED: To provide a driving control device for a vehicle capable of causing no problems in securing safety even if a driver steps on a brake when a situation needing a sudden stop occurs in an inter-vehicle distance control mode. SOLUTION: A driving control device for a vehicle is equipped with an inter- vehicle distance control mode 303 for automatically driving so as to follow an ahead going vehicle keeping a fixed inter-vehicle distance previously established and is made up such that the inter-vehicle distance control mode 303 is released and replaced by a manual driving mode 301 by a driving control operation of the vehicle conducted by a driver. In this event, an urgent stop mode 305 is provided which is adapted so as not to be released even when the driving control operation of the vehicle is conducted by the driver. The urgent stop mode 305 exhibits its function when a situation needing a sudden stop occurs and acts to generate necessary braking force.

Abstract: PURPOSE:To prevent drift stream of molten steel poured into a mold by independently controlling supplying rate of inert gas blown into the poured molten steel from right and left sides through a permeable porous brick arranged at inside of semi-circular divided slits. CONSTITUTION:The drift stream of molten steel in the mold 2 is supervised with a temp. supervisory device 10, and when the temp. difference detected with thermocouples 9a, 9b at right and left sides exceeds the prescribed threshold value, it is decided that the drift steam develops.
