摘要： By eliminating a current of bit lines which is generated regularly by an off-leak current in memory cells, the number of memory cells per bit line is made to increase, large storage capacity of the memory cell array is achieved, and a semiconductor memory device capable of reducing a chip area is provided. In order to achieve it, provided is a source line potential control circuit for setting a source potential of transistors included in the memory cells being selected by row selection signals at a ground potential, and for setting a source potential of the transistors included in the memory cells being set as a non-selection state by the row selection signals at a power potential. A potential difference between sources and drains of the transistors included in the memory cells of the non-selection state is thereby reduced, and the leakage current is eliminated.

摘要： A Czochralski method of producing a single crystal silicon ingot having a uniform thermal history. In the process, the power supplied to the side heater is maintained substantially constant throughout the growth of the main body and end-cone of the ingot, while power supplied to a bottom heater is gradually increased during the growth of the second half of the main body and the end-cone. The present process enables an ingot to be obtained which yields wafers having fewer light point defects in excess of about 0.2 microns, while having improved gate oxide integrity.

摘要： To read data stored on a memory cell transistor with a floating gate, a flash memory uses: a single-gate reference transistor; a differential sense amplifier; and a gate voltage generator for generating a gate voltage for the reference transistor. The gate voltage generator includes: a dummy cell transistor, which has the same structure as the memory cell transistor and has been turned ON; a current mirror for creating a current proportional to a drain current of the dummy cell transistor; an NMOS transistor for generating a gate voltage for the reference transistor in accordance with the current created by the current mirror; and a voltage hold circuit for holding the gate voltage generated. Even if temperature or fabricating process conditions have changed, this construction ensures accurate and high-speed read operation.

摘要： A ferroelectric liquid crystal device of a cell structure having a suppressed increase of cell thickness along a cell side is constituted by disposing a ferroelectric liquid crystal between a pair of electrode plates each sequentially provided with an electrode, an insulating film and an alignment film on a substrate. The alignment film is provided with a surface unevenness for suppressing a liquid crystal movement causing the increase in cell thickness. The surface unevenness is provided to the alignment film directly or to the insulating film below the alignment film, e.g., by wet forming the relevant film by using at least two solvents having different boiling points or dispersing fine particles within the relevant film, optionally followed by removal of the fine particles.

摘要： A transmission for an electric vehicle that allows forward movement in a first shift stage with hydraulic pressure failure and permits forward and rearward towing. The first shift stage of the transmission T is established by a main first-shift gear 19 which is brought into and out of engagement with a main shaft Sm connected to an electric motor Mm through a towing clutch 50, and by a counter first-shift gear 26 carried on a counter shaft Sc with one-way clutch 47 interposed therebetween. During backward towing of the vehicle, the rotation of a driven wheel is reversely transmitted by way of the counter shaft Sc, the one-way clutch 47, and the counter first-shift gear 26 to the main first-shift gear 19, but by actuating the towing clutch 47 into a disengaged state to disengage the main first-shift gear 19 from the main shaft Sm, the electric motor Mm can be prevented from being forcibly driven and being damaged.
