Title: Production of porous hollow yarn membrane
Inventor: TAKAHARA KAZUAKI
IPC: D06M23/00
Filed: 1987-07-23
Abstract: PURPOSE: To produce a porous hollow yarn membrane excellent in membrane characteristics by kneading polypropylene with an organic filler and a crystal nucleating agent good in dispersibility at the time of melting the polypropylene, melt spinning the resultant kneaded mixture into the shape of a hollow yarn, then bringing the melt spun yarn into contact with a cooling solidifying liquid having a specified specific heat capacity and subsequently carrying out an extracting treatment of the filler and the cooling solidifying liquid. CONSTITUTION: Polypropylene and an organic filler and a crystal nucleating agent uniformly dispersible in a molten state of the polypropylene are kneaded and then melt spun with an annular spinneret. The discharged material is then brought into contact with polyethylene glycol having 0.3-0.7 cal/g specific heat capacity without compatibility with the organic filler, cooled and solidified. The resultant material is subsequently treated with an azeotropic mixture of 1,2,2-trichloro-1,2,2-trifluoroethane with ethanol or acetone dissolving the filler and the cooling solidifying liquid without dissolving the polypropylene to extract and remove the filler and the cooling solidifying liquid. Thereby, a porous hollow yarn membrane excellent in membrane characteristics is obtained.

Abstract: PURPOSE:To facilitate an operation for confirming a photographed image by providing a control means for actuating a reproducing means while a recording designation means is in a prescribed state and reproducing the image which is recorded just before. CONSTITUTION:After a photographed image signal by an image pickup circuit is recorded on the track of a magnetic disk 10 where a magnetic head 12 is positioned, a host control circuit 42 examines whether it is a consecutive photographing mode or not by a single/consecutive photographing switch 54 when a recording switch 50 keeps being on. When it is not the consecutive photographing mode, a control signal E2 is made low and power supply to the image pickup circuit is interrupted and a switch 31 is connected to a contact (a) to make the control signals E3 and E4 high, so that power is supplied to a reproducing amplifier 22 and a reproducing signal processing circuit 34. Thus, the reproduced video signal of the image which is recorded just before is outputted from a reproduced video output terminal. Therefore, the recorded image is quickly confirmed because the recorded image is automatically repro duced by keeping the recording switch 50 in an on-state after performing record ing in the single recording mode.
