Title: Semiconductor non-volatile memory
Inventor: ARIGA RIE
IPC: H01L29/788
Filed: 1986-02-18
Abstract: PURPOSE:To contract a memory cell by forming an erasable/writable floating gate type memory cell in a 1-transistor structure. CONSTITUTION:A memory cell has a thin portion in a first insulating film 3 directly under a floating gate 4, and a second insulating film 5 on the gate 4 and a third insulating film 7 on a semiconductor substrate half region of a drain 2 side are integrally formed. A control gate 6 and a select gate 8 are formed by forming in advance one conductivity type polycrystalline silicon film, ion implanting impurity atoms to invert it to reverse conductivity type to form the layers. In the thus formed floating gate type memory cell, a high voltage is applied to the gate 6 and the gate 8 at erasing time, and a low voltage is applied to the control gate and a high voltage is applied to the select gate at writing time. In this case, the control gate and the select gate are never shortcircuited due to the reverse bias of a diode.

Title: Copying machine
Inventor: MURAOKA TOSHINORI
IPC: G03G15/00
Filed: 1984-02-24
Abstract: PURPOSE:To take an excellent copy through easy operation by providing a control part which detects abrupt variation of the output signal of a sensor outputting a signal corresponding to the quantity of reflected light from an original and operates a copy paper feeding part. CONSTITUTION:A thick book as an original D is placed on an original platen 1 and a print key (not shown in figure) is operated. Then a light source 21 and reflecting mirrors 22, 23, and 24 move as shown by arrows and a photosensitive drum 31 rotates as shown by an arrow B. The quantity of reflected light from the original D is extremely small until scanning exposure by an optical part 2 advances to the front edge of the original D, and increases abruptly when the exposure reaches the front edge of the original D, so a decision circuit 53 outputs a signal for starting a register roller 41 and the signal is applied to a driving circuit while delayed by a specific time through a delay circuit 54. Consequently, the front edge of copy paper P fed by the register roller 41 is aligned to the front end of an image on the photosensitive drum 31 and an excellent copy is taken.
