Title: Stabilizer for aqueous solution of formaldehyde
Inventor: WATANABE NORIYOSHI
IPC: C07C47/058
Filed: 1987-06-08
Abstract: PURPOSE:To obtain the titled stabilizer having excellent preventing effects on formation of sediment and on formation of formic acid with time, comprising a specific polyvinyl acetate as a raw material, by neutralizing an acid catalyst to be used in saponification reaction and formalization reaction thereof with an alkanolamine into a specific pH. CONSTITUTION:A polyvinyl acetate having 1,000-5,000 number-average molecular weight is saponified to give a polyvinyl alcohol having >=90% saponification degree, which is subjected to formalization reaction with formaldehyde or paraformaldehyde in the presence of an acid catalyst in a solvent under heating to give a polyvinylformal compound having 65-90% formalization degree. Then the polyvinylformal compound is mixed with an addition derivative of an alkanolamine and/or an aliphatic primary amine with an alkylene oxide in an amount enough to neutralize the catalyst and to adjust the solution to pH >=4.0 to give a stabilizer which has inhibitory action not only on sediment formation of paraformaldehyde during preservation of a highly concentrated aqueous solution of formaldehyde with low methanol content but also on formation of formic acid with time during high-temperature preservation.

Title: Residual amount meter for sprinkler
Inventor: KOBAYASHI ATSUSHI
IPC: G01F23/28
Filed: 1987-06-05
Abstract: PURPOSE:To prevent the lowering in the residual amount detecting function when the quantity of light is insufficient, by mounting a correcting optical sensor for detecting the quantity of light outside a chemical agent tank and comparing the quantity of the receiving light of said sensor with that of the residual amount detecting optical sensor in the chemical agent tank. CONSTITUTION:When a chemical agent 6 is received in a chemical agent tank 1, since a sensor rod 2 is immersed in the chemical agent 6 up to the midway thereof, the quantities of the receiving light of residual amount detecting optical sensors 3-3, 3-4, 3-5 are reduced and the quantities of the receiving light of optical sensors 3-1, 3-2 do not change. In this case, since the quantity of the light received by the residual amount detecting optical sensor 3 is not always constant, a correcting optical sensor 4 detects the quantity of light outside the chemical agent tank 1 to send the signal corresponding to the quantity of light to a display part 5. Since the quantity of light of the residual amount detecting optical sensor 3 and that of the correcting optical sensor 4 are corrected by a compensation circuit 8, the display part 5 receiving said signal displays the signal as a proper residual amount value by an LED 9.

Filed: 1979-11-01
Abstract: PURPOSE: To control the exchanged heat quantity between two fluids by providing a partition doubly, putting fluid in between the partitions, and changing the level of the fluid.  
     CONSTITUTION: In the method wherein heat exchange is performed by making process fluid A and medium fluid B, whose temperature is different from each other, contact with each other with partitions 2 and 3 between them, these partitions 2 and 3 are provided doubly, the liquid 4 is put in a space 5 surrounded by the partitions 2 and 3, and the level thereof is changed. When the surface H of the liquid 4 rises, the heat transferring area of two fluids A and B between the partitions 2 and 3 is enlarged and the exchanged heat quantity increases. And when the surface H of the liquid lowers, the heat transferring area of two fluids A and B between the partitions 2 and 3 is reduced and the exchanged heat quantity is also reduced. By changing the level of the liquid 4 by a proper means in this way, the exchanged heat  quantity can be controlled.

Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To put a random longitudinal line flow of products in order by providing first and second stopping means fitted capably of being reciprocated in the longitudinal direction perpendicular to the carrying direction of products and a first sensor causing reciprocation of them in the longitudinal direction. SOLUTION: A robot transfer device 200 selectively draws out products out of specification from products of 2 x 8 pieces. Gaps or random change are generated in the flow of the products by the drawn products. A putting-in- order device 995 drives a carrying device with doubling preventing rail, and advances it up to an output end 915 along the direction of the arrow mark C under products 20d. At this time, by setting first and second stopping means 904a, 904b on the descending position, advance of a leading product is obstructed, and succeeding product is also brought in contact with the leading product so as to stop. The fact that a specified number of packages are put close with no gap is confirmed by a sensor, and hence the specified number of packages are put in order.
