IPC: B29C55/12
Filed: 1990-04-18
Abstract: PURPOSE:To obtain a biaxially stretched polyester film for forming excellent in formability, thickness evenness, heat resistance and surface gloss from a polyester film having specific charcteristics. CONSTITUTION:In polyester constituting a film having characteristics represented by formula [wherein Gs(60 deg.) is the glossiness of a film, X100 is a fine crystal size (A) measured by X-ray diffraction and F100 is strength (average value in the longitudinal and lateral directions of a film ; kg/mm<2>) at the time of 100% elongation in a 150 deg.C atmosphere], the ratio of polyethylene terephthalate is pref. 50mol.% or more, further pref. 70mol.% or more. When the ratio of polyethylene terephthalate is below 50mol.%, no pref. effect is obtained because the strength and heat resistant of a film are lowered. Further, it is also pref. to add fine org. or inorg. particles in order to impart easy slip properties and surface gloss to the film and, as fine particles, it is especially pref. to mainly use fine silicon oxide particles in order to impart desired surface gloss efficiently.

IPC: G06F3/00
Filed: 1990-04-17
Abstract: PURPOSE:To prevent the generation of the undershoot or overshoot of a signal by inserting an inductor between an FDD driver in an FDD device and a signal line. CONSTITUTION:When a signal (a) is inputted to the FDD driver 14 in the FDD device 11, the driver 14 outputs a signal (c) obtained by inverting the signal (a) to a host receiver 15 in a host device 12 through an interface cable 13. When the characteristic impedance of a terminal resistor 16 is not matched with that of the cable 13, the signal (c) includes a condition for generating undershoot or overshoot, but the sudden change of a signal current can be suppressed by the action of the inductor 19 inserted into the signal line and the undershoot or overshoot can be suppressed.
