Title: Gas permeable cell
Inventor: ITOU YOSHIMASA
IPC: B01D53/22
Filed: 1979-08-31
Abstract: PURPOSE: To easily obtain the enriched gases of each component gas from gas mixture by a small-size and simplified structure of gas-permeable cell with selective gas-permeable membranes forming an impermeable gas chamber with a spirally structured partition wall.  
     CONSTITUTION: In the first chamber 8, two side walls are made up of two selective permeable membranes 10, and a gas outlet 5 centered partition wall 9 of a spiral structure is formed. The gas mixture is introduced through an inlet 3 at a definite flow rate and a definite pressure and then sent to the said impermeable gas chamber 8, the inside of which has a spiral structure formed by the partition wall 9, in which the vertical area of the inlet is set up to 1.2 to 4 times as much as that of the outlet in case the partition wall 9 is spread out straightly. Furthermore, in all places, the ratio of the distance between the walls to the distance between the membranes is set up to 1 or less. Gas in the impermeable gas chamber 8 partly passes through the membrane 10, gathers in a permeable gas chamber 7, and goes out of a permeable gas outlet 4. On the other hand, the remaining gas passes through a valve 6 and then goes out of the outlet 5 as low-permeable gas-enriched gas.

IPC: G11B15/54
Filed: 1984-05-31
Abstract: PURPOSE:To eliminate the necessity of the capstan and pinch roller from a tape recorder device so as to simplify the constitution of the device, by controlling the rotating speed of the a reel motor in accordance with the running speed of a tape so that the running speed of the tape can be fixed constantly. CONSTITUTION:The running speed of a tape is detected by means of a speed detector 14 and the rotating speed of a reel motor 19 is controlled in accordance with the detected result so that the tape running speed can be fixed constantly. When such an arrangement is made, various problems caused by the installation of capstans and pinch rollers as usually seen in conventional tape recorder devices can be eliminated completely and the tape recorder device utilizing this arrangement can be made simpler in constitution, smaller in size, and lighter in weight. Especially, the electric current consumption of the reel motor 19 can be reduced sharply. Moreover, since it is also arranged that the tape end detection can be made by utilizing the stop of the FG pulse generation of the speed detector 14 due to the stop of the rotation of a roller 14b for detecting the running speed of the tape, the constitution can be simplified from this point.
