Title: Endless conveyor formed of tooth plates
Inventor: DRIBURG GUNTER
IPC: B65G17/08
Filed: 1982-08-17
Abstract: In a conveyor chain consisting of inverted tooth plates which form a chain belt with a substantially continuous surface, the tooth plates are connected together by means of link pins in the form of rocking link pins which allow the plates to rotate relative to each other.

Title: A semiconductor integrated circuit memory device
Inventor: OGATA MASAHIRO
IPC: H01L29/788
Filed: 1985-03-22
Abstract: In a semiconductor memory device provided with a plurality of memory cells each comprised of an insulated gate field effect transistor having first and second semiconductor regions of a first conductivity type formed separately from one another in a substrate of a second conductivity type, two bits can be stored in each transistor.
