Title: Evaporation-concentration using laminated liquid-permeable layer
Inventor: KOJIMA KATSUYOSHI
IPC: B01D1/00
Filed: 1979-04-13
Abstract: PURPOSE: To simplify operation control through saving of energy consumption for liquid separation using evoporating-concentration by a method wherein solution- permeable thin layer is bonded to a heat-transmitting plate, the assembled member is laminated, and heat is given to the lowest heat-transmitting plate while solution is flowed on each thin layer.  
     CONSTITUTION: Solution-permeable thin layer 1 is bonded to non-solution-permeable heat-transmitting plate 2, the assembly is laminated, with separation by parallel space 4, and their side and bottom faces are covered with heat insulating material 5. Raw solution is flowed in each layer 1, and when solution diffuses and permeates the layers, heat is given to the lowest-layer heat-transmitting plate 3. The heat passes through each layer and discharged from the topmost layer. During this process, liquid evaporation and condensation phenomenon occurs between each layer. The process is effective in preventing heat energy dissipation, and separation due to phase change becomes highly efficient per unit calory.

Abstract: PURPOSE: To prevent damage of a shaft by interposing a key between a hollow coupling connecting a motor side to the shaft and the shaft, and bringing the key into contact with the shaft by a strong force compression means while holding the key under a weak force at the time of releasing. CONSTITUTION: A slot 40 is formed at an upper end 24 of a shaft 15, a hollow coupling 42 is arranged, and a vertical rotational shaft is formed. Then, an upper end thereof is connected to a motor side output hub 66 by a pin 70. A key 44 is arranged at an opening of a coupling 42 and engaged therewith, and brought into contact with the shaft 15 by a fastening screw 46 being a compression means. A holding means is formed of a bolt 48 inserted into a threadless opening of a side wall of the coupling 42 and a spring 50. The spring 50 has a weaker acting force than the screw 46, and the key 44 is brought into contact with the shaft 15 by the action of the screw 46 while the key 44 is separated from the shaft 15 when released. Accordingly, the shaft is increased in its strength for lessening its damage.

Abstract: PURPOSE: To bring efficient printing to effect while preventing a system from running into trouble, by completing printing of one page without stopping the printing in its middle even if the completion of the span of the life of an ink ribbon would be detected in the middle of printing data for one page.  
     CONSTITUTION: Central processor 11 outputs and supplied print data to interface circuit 17 of online printer 16 in sequence by way of communication circuit 14 and MODEM 15 so as to perform printing operation according to the decision result of circuit 17. Every time one line of data is printed out, control circuit 18 outputs a print line signal, which is counted by counter 19 and when the completion of the span of the life of a ribbon is detected by the contents of the counting of counter 19 in the middle of one line printing, logic value "1" is added to AND circuit 21. At this time, since the output of page-turning detecting circuit 20 is zero, circuit 18 outputs no signal even when the completion of the span of the life of the ribbon is detected and carries the printing operation on. Then when circuit 20 detects the feed of a line, central processor 11 is informed of the completion of the life span of the ribbon, which is replaced at the time of the feed of a line.

Title: Stainproofing agent
Inventor: TAMURA MASAYUKI
IPC: C09K3/00
Filed: 1989-02-28
Abstract: PURPOSE:To obtain a stainproofing agent which imparts stain resistance and stain-removing property to sealants or paints by mixing an organosilicon compound having both polyfluoroalkyl and hydrolyzable functional groups with a specific polyorganosiloxane. CONSTITUTION:This stainproofing agent is obtained by mixing an organosilicon compound (A) having both polyfluoroalkyl and hydrolyzable functional groups with a polyorganosiloxane (B) having both polyoxyalkylene and polyfluoroalkyl groups. The mixing ratio of the components (A) to (B) can be varied in the range of 95/5-5/95. However, when the amount of the component (A) is too large, the stain resistance is improved but the stain removing property is insufficient. On the other hand, when the amount of the component (B) is too large, although the stain resistance lowers, the stain removing property is improved. A preferable range is 70/30-10/90.
