TA7082, 14pin TO-3 datasheet help!

[Junm]

Hi does anybody Know what this is? is it an IC in A to-3 package and anybody has datasheet for this? also This TA78005M that I think is a regulator.

Found them in a bulk sale of old trannies with some kinda old and unfamiliar semiconductors.

It seems nobody used this device in the past. can't find any info with this.

The information is probably only in pre-internet Japanese datasheets of a certain vintage, to me even the 14 pin TO3 package is novel, but its fairly likely its a power opamp, power amp or perhaps a motor driver.

Third try right Mark --I found an old -1974 IC equivalent book by Bernard (UK) ,its equivalent is an 8482 --driver amp for DC motor control by Toshiba .

Thanks at least i have an idea for that 14 pin thing. the ta7005m is A 5v regulator as what i heard. Maybe it will be good for a museum thing.
