Patent JP-S6361139-A (JP)
Title: Apparatus for measuring molecular weight of liquid
Inventor: TAMAI TETSUO
IPC: G01N13/00
Filed: 1986-09-01
Abstract: PURPOSE:To obtain the title measuring apparatus capable of determining the mol.wt. of a solvent containing a solute as a whole by calculating mol.wt. from osmotic pressure. CONSTITUTION:A cell 11 is arranged to a measuring region 2a and a chamber 3 is allowed to fall to inject a solvent specimen containing a solute in the cell 11 from a specimen injection port 4a. The specimen receives the heat from a base stand 2 to be heated to definite temp. and evaporated based on the concn. of the solution to generate steam pressure. At this point of time, an osmotic pressure measuring circuit 7 allows a current to flow to a thermocouple 5 to lower the temp. of the specimen and dew condensation is generated in a junction part 5a and the current is subsequently cut off. By this mechanism, the injection part 5a receives the heat from the circumference and begins to rise in temp. but keeps a parallel state at equilibrium temp. by the solvent adhered by dew condensation. When the temp. T1 when the junction part 5a reaches the equilibrium state for the first time is detected by the thermocouple 5 and the temp. T2 in the chamber 3 is detected by a thermocouple 6, the difference DELTAT between both of them is proportional to the osmotic pressure P of the specimen. An operation circuit 9 calculates a mol.wt. M based on the data preliminarily inputted and the osmotic pressure P according to a predetermined formula.

Then a bleached craft pulp is used by about 100% to form the surface layer (b) having >=80% whiteness degree. Then a pulp showing >=70% whiteness degree prepared from recycled newspaper by removing ink and bleaching is used by 100% to form the layer (c) just under the surface. The wt. of each layer per unit area is 150 to 700g/m<2> .  The multilayered paper board thus prepared is used to obtain a punched sheet having rules and notches. Then a carton is produced from the sheet.
