Title: Charge pump memory
Inventor: SASAKI NOBUO
IPC: H01L27/10
Filed: 1982-09-22
Abstract: PURPOSE:To obtain a charge pump memory by an LOCOS method without using avalanche multiplication, by not extending the drain region, which is provided in a floating region on an insulating substrate, to a field oxide film. CONSTITUTION:A p type floating region 2 on an insulating substrate 1 is surrounded by a field oxide film 9, and n<+> layers 3 and 4 are formed thereon. At this time, the end part of the drain 3 is not extended to the oxide film 9, but a p region is provided. The thickness of a p layer 2A below the drain 3 is set so that a depletion region reaches the substrate 1 by a specified drain voltage VD. An electrode 5 is contacted with the surface of a region 2B. Therefore, the surface area is increased, and excellent ohmic contact is obtained. By the voltage VD, which is always applied to the drain electrode 5, the p layer 2A below the drain 3 is depleted, and the floating region 2 and the drain 5 are turned OFF. In order to erase the memory, the voltage VD is made to be zero. Then, the depletion layer is reduced, the p layer 2 and the drain electrode 5 are connected, and the memory is erased by the outputting and inputting of electric charge.

Title: Three pole magnetic head with reduced magnetic flux leakage
Inventor: SHIYAIAMU CHIYANDORA DASU
IPC: G11B5/245
Filed: 1990-06-22
Abstract: PURPOSE: To optimize reading and writing characteristics by guiding a magnetic flux to a remotely arranged magnetic flux sensor with a reading pole arranged within a gap between a pair of writing poles. CONSTITUTION: The magnetic flux is guided to the magnetic flux sensor from a medium with the reading pole 16 during lead back. Writing poles 12 and 14 are worked as a shield shutting a reading magnetic flux out of the reading pole 16 until a source (recorded bit) almost comes just under the reading pole 16. A narrow lead back pulse is provided by this configuration, and a high density of record is allowed. The magnetic flux is driven to the pole 14 from the pole 12 with a writing coil 25 during writing, the reading pole 16 is saturated, while an effective reading gap distance is approximately made to be its half. By this way, high writing is allowed to obtain an excellent overwriting from a magnetic field, and an excellent solution is simultaneously obtained from a small effective reading gap during lead back.
