Title: Reading circuit of magnetic storage device
Inventor: TANAHASHI YUTAKA
IPC: G11B5/09
Filed: 1981-07-10
Abstract: PURPOSE:To reduce the crossfeed noise, by making the terminal voltage of a writing head pass through a low-pass filter having the equivalent transmitting properties of a reading head and then adding the terminal voltage the reading signal supplied from the reading head. CONSTITUTION:In the writing/reading mode of information, a writing data (f) is converted into a writing current through a writing driving circuit 9, and a recording medium is magnetized by a writing head 10. This magnetization of the recording medium is reproduced by a reading head 11 and then amplified by the amplifiers 12 and 13. Then the reading data is discriminated by a data shaping circuit 14. The terminal voltage of the head 10 is fed to an addition amplifier 13 through a low-pass filter 15 and added with the output of the amplifier 12. Thus the crossfeed noise is offset.

Title: Ethylene-vinyl alcohol copolymer resin composition
Inventor: OOZEKI YUKIO
IPC: C08L23/00
Filed: 1980-08-08
Abstract: PURPOSE: To improve drawdown properties and impact resistance of an ethylene- vinyl alcohol copolymer resin, by incorporating an alcohol-containing plasticizer and boric acid or a borate with the copolymer resin.  
     CONSTITUTION: 100pts.wt. Ethylene-vinyl alcohol copolymer resin (EVOH) having an ethylene content of 25W50mol% and a saponification degree of 96% or more is blended with 12W15pts.wt. alcohol-containing plasticizer and 0.05W3pts.wt. boric acid or borate. If the ethylene content of the EVOH to be used is less than 25mol%, the EVOH is hard to mold as the molding temperature is near its decomposition temperature. If the ethylene content exceeds 50mol%, an excellent oil resistance of the EVOH deteriorates and also its softening point is lowered. If the degree of saponification of the EVOH is less than 96%, its oil resistance and resistance to gas permeation are deteriorated. If the amount of boric acid or a borate mixed with the copolymer resin is less than 0.05pts.wt., the EVOH will have poor drawdown properties and if the amount exceeds 3pts.wt., troubles of surface roughening and a nonuniform section of EVOH molding will occur.
