Abstract: PURPOSE:To reduce the occupying area of a memory cell by forming part of a trench sidewall for forming a transistor in contact with a dielectric isolation region. CONSTITUTION:A trench 9 is formed on a substrate made of a P<+> type layer 1 and a P-type layer 2, and a vertical MOS transistor is formed at its top with a polysilicon film 7 as a gate electrode, N<+> type layers 8, 8' as source, drain, and a gate oxide film 6. A thick SiO2 film 3 for electrical dielectric isolation of each memory cell is provided in contact with right and left trench sidewalls. An N<+> type layer 8 which becomes a bit line is present between dielectric isolation films 3', 3'' formed on the side opposite to the film 3 and the trench sidewalls. Accordingly, the trenches can be disposed near twice as small as the width of the layer 8, thereby reducing the occupying area of the memory cell.

Patent JP-S5983838-A (JP)
Title: Clutch device
Inventor: DEEBITSUDO JIERARUDO RUISU
IPC: F16D48/02
Filed: 1983-09-30
Abstract: A hydraulically engaged clutch comprises an actuating chamber wherein pressurized hydraulic fluid acts on a piston (40) to engage the clutch and a clutch chamber (26) for clutch cooling fluid which cools the stack of discs (32, 34). A spool valve (64) in a radial passage (60) in the clutch housing controls flow of cooling fluid to the clutch chamber (26) and is acted upon by the pressure in the actuating chamber to keep the valve open while clutch-engaging pressure is supplied from a pump (42). The spool (64) is also acted on by centrifugal force to close the valve when pressure in the actuating chamber falls sufficiently. The clutch chamber then drains through a passage (66) in order to avoid viscous drag. Preferably the valve (64) moves to the open position, as pressure rises in the actuating chamber before the piston (40) engages the clutch, in order to ensure cooling during engagement.
