Title: Tension control device for winding-rewinding device
Inventor: TADA SHIGEHIRO
IPC: B65H23/185
Filed: 1995-03-27
Abstract: PURPOSE: To carry out stable tension control at the time of winding and rewinding irrespective of set speed by transforming tension reference into the reference value of motor current, and giving this reference value of motor current to an A.C.motor. CONSTITUTION: The output of an efficiency correction circuit 7 and an adjustable speed correction circuit 1 is inputted into a correction rate compensation circuit 8, and the inverse function of motor efficiency is integrated into a correction quantity by the correction rate compensation circuit 8 to compute the correction quantity responding to the number of revolutions of the motor, and the correction quantity is added to a tension-current substitution circuit 4 to form tension reference, which is transformed into the reference value of motor current by the tension-current substitution circuit 4, and the reference value of motor current is given through a speed-tension change-over circuit 5 and a polarity change-over circuit 6 to a A.C.motor.  Thus since the correction in view of control is carried out to the variation of motor efficiency to make apparent motor efficiency within a variable speed range constant, stable tension control can be executed at the time of the winding and rewinding of a long sized material irrespective of set speed.

Title: Thin film evaporation
Inventor: OKADA TAKEO
IPC: B01D1/22
Filed: 1978-06-09
Abstract: PURPOSE:To prolong service life of a thin film evaporator by preventing heat transmission decrease and screw wear, thin film is formed on the internal surface of rotary evaporator shell and a faster rotating screw is used to transfer treating liquid. CONSTITUTION:The evaporator shell 2 has on its outer periphery a jacket 3 for heating medium, and is rotated by a pulley 12. The shell 2 is provided in its inside with screw having blades 10 which has the liquid inlet 4 and is rotated by pulley 11 at a faster rate than the shell 2.

Title: Optical energy conversion system
Inventor: HAYAKAWA KIYOSHI
IPC: F24S90/00
Filed: 1983-04-19
Abstract: PURPOSE:To increase the solar energy conversion efficiency of the titled system by a method wherein in the case of the optical energy conversion system using a photochemical heat storage material adopted to convert solar energy into thermal energy for the collection and storage of heat, the photochemical heat storage material is temporarily isolated from a reaction system during or after the application of the solar rays upon the material. CONSTITUTION:A cyclohexane solution of trans-azobenzene refined by recrystallization is received within a qualtz cell 4 and the solar rays are applied on the solution at normal temperature. Then, after the application of the solar rays, the solution is circulated and cis-azobenzene generated from the solution is absorbed completely by an absorbing column 6 through a liquid inlet port. After that, the circulation of the solution is stopped and then the application of the sunlight on the solution is performed and so on in a repetitive fashion during which only non-reacted trans-azobenzene is repeatedly applied with the sunlight. Consequently, the solar energy conversion efficiency of the system increases remarkably as compared to a case where the absorbing column 6 is not used. The generated substance absorbed by the column 6 is used after it is transferred into a storage tank by heating the column or by adding a solution of a separating agent to the column.
