IPC: G11B5/73
Filed: 1979-09-25
Abstract: PURPOSE: To prevent the variance of magnetic characteristics by removing pinholes, projections, etc., of a magnetic layer formed on a base material, by dipping a disk base in a chemical that dissolves either or both of residual abrasive grains and base after the base material of a magnetic disk is polished.  
     CONSTITUTION: This describes a magnetic memory body such as a magnetic disk. The surface of base material 2, such as a hard metal, e.g. Ni-P nonmagnetic alloy and Al 2 O 3  and metal oxide, formed on aluminum-alloy-made disk base 1 is polished by using abrasive grains of SiO 2 , Al 2 O 3 , SiC, etc. Then, the base is washed and dried after the Beilby layer (amorphous layer) or plastic deformed layer of base material 2 and abrasive grains remaining on base material 2 are dipped in a chemical that dissolves abrasive grains or defect parts of base material 2 or in a chemical that dissolve abrasive grains and defective parts simultaneously. Thus, extremely small defectives such as pinholes are prevented from being made in magnetic medium layer 3 to be provided on base material 2. On layer 3, protective film 4 may further be formed. Thus, an excellent memory body can be obtained which has neither a dropout nor deterioration in S/N.

Title: Monostable multivibrator
Inventor: NAGANO KATSUMI
IPC: H03K3/0232
Filed: 1979-09-25
Abstract: PURPOSE:To improve electric power voltage dependency by setting the charging current of a capacitor, provided to the input terminal of a comparator, in proportion to an electric power voltage. CONSTITUTION:The collector voltage of transistor Q2 constituting constant current source 11 is equal to inverted input voltage (Vcc/2) of operational amplifier. Further, transistors Q2 and Q3 are operational ones and connected in common at bases, so that collector currents of both the transistors will be equal. Here, the magnitude of constant current (i) is in proportion to Vcc. The charging current of capacitor C is therefore linear. Additionally, since reference voltage Vref to comparator 2 is also in proportion to the electric power voltage, the time required for the inversion of comparator 2 can be made unrelated to the electric power voltage.
