Title: Flowability improver
Inventor: ITO TAKESHI
IPC: C10L1/192
Filed: 1985-02-20
Abstract: PURPOSE:To provide a flowability improver capable of imparting an excellent flowability to both of an oil having a wide boiling range and an oil having a narrow boiling range and effectively preventing a filter from clogging by virtue of its smooth passage through the filter, which comprises a particular polyester derivative compd. CONSTITUTION:An alkylene oxide is added to a fatty acid. A dibasic acid is added to the adduct, and an alkylene oxide is further added to the adduct. If necessary, the step of the addition of a dibasic acid and the step of the addition of an alkylene oxide are repeated. An alkylene oxide adduct thus obtained is crosslinked with a dibasic acid to obtain a polyester derivative compd. of the formula (wherein R<1>-R<2> are each independently a 9-29 C alkyl; A is a 2-4 C alkylene; Y is an alkylene or alkenyl group or arom. residue; l and m are each independently an integer of 1-25; and n is an integer of 1-10). The polyester derivative compd. is used as an essential component and, if necessary, other flowability improvers (e.g.: ethylene-vinyl acetate copolymer) may be added thereto in an amount of 0.2-10pts.wt. per pt.wt. polyester derivative compd.

Filed: 1995-02-21
Abstract: PURPOSE: To provide a take-up spool driving mechanism having a take-up spool, driving device and member to be driven. CONSTITUTION: This mechanism has a driving device 36, member to be driven and take-up spool 28. The driving device 36 has projections 68 for driving a pinion in both directions to form gaps, and a finger 74 of flexible arm 70 of the driving device 36 drives the take-up spool 28 in film take-up direction while being engaged with an inner tooth 34 of the spool 28. The finger 74 is disengaged by bending the arm 70 inside and forming gaps in inverse direction to freely revolve the spool 28. In addition to the selective engagement with the take-up spool 28 and the cut-off of clutch, the finger 74 is re-engaged with the inner tooth 34 by ] forward revolution and forms the gaps. Thus, when a motor 12 is stopped after take-up action and a film is matched with a film inlet/outlet, for example, the take-up spool 28 is fixed so as not to be freely revolved.

Abstract: PURPOSE:To prevent a bit of old information from mixing to a bit of new information, and to reduce the generation of a secondary distortion, by setting the angular shape ratio of a magnetic recording medium in a vertical direction below 0.6, and performing a preceding erase with a DC current. CONSTITUTION:An easy magnetizing shaft is prepared on the film plane of a magnetic layer in the vertical direction, and a magnetic head 12 is arranged facing with the magnetic layer of a recording medium 11 having the angular shape ratio of below 0.6 in the vertical direction.
