Title: Bit line sense-amplifier circuit
Inventor: GO NAGAO
IPC: G11C11/4091
Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To suppress the noises of a power supply line with the sudden change of a restore current by mounting a parallel driver, in which a voltage state is altered in response to a control signal, to a restore signal circuit. SOLUTION: A control signal cont is connected to an output from a voltage sensor. When the control signal cont is at 'L', a MOSFET Q18 is conducted, and a MOSFET Q14 is conducted and voltage Vcc is transmitted to a signal terminal rtoi when signals /R1, /R2 enabled after time delay by a control signal blp1 are transferred to 'L', and voltage (Vcc-Vtp) (Vtp≈1V) is transmitted successively to the signal terminal rtoi through MOSFETs Q16, 17. When the control signal cont is at 'H', a MOSFET Q19 is conducted, the MOSFET Q14 is conducted when the signals /R1, /R2 are transferred to 'L', and the signal terminal rtoi is supplied with charges through the MOSFETs Q16, 17 in series.

Abstract: PURPOSE:To position a pellet division on a wafer and a photo-mask with high precision by forming the wafer having structure having target marks at the positions of a longest distance on a diagonal line tying the corner sections of the pellet division. CONSTITUTION:A wafer having the structure having target marks 6a, 6b at the positions of the longest distance on a diagonal line tying the corner sections 5a, 5b of a pellet division 3 is formed. An XY table or a photo-mask is moved by a fixed quantity in the XY directions so that an external corner section 7a in one target pattern 6a is positioned at a position where it is brought into contact with the photo-mask in the pellet division on the wafer. The quantity of displacement (d) between each corner section 7b in the other respective target pattern 6b is detected mechanically. The pellet division is shifted by a fixed quantity in the theta-direction centering around the corner section 7a by the quantity of displacement (d), thus resulting in d=0.

Abstract: PROBLEM TO BE SOLVED: To achieve a high level cleanliness factor as well as to make this high cleanliness factor maintainable even at the time when an elevator goes up or down by forming such a down flow as having a uniform air-current distribution in the elevator. SOLUTION: A structure in a car 6 is formed into a down-flow system that makes clean air be blown out of the whole ceiling and simultaneously be inhaled from the whole floor, counterbalancing it into a uniform air-flow distribution, therefore any deviation in an air current and a stagnation area due to inequality will in no case occur, so that a high cleanliness factor is made so as to be maintainable in design. Accordingly, in a secondary an air charging chamber 9a, an air velocity between both lower parts of a discharge port 10 and a filter 11 is varied, so that an opening factor of a vent hole in the central part of a ceiling member 7 is made to be larger than the outer boundary, whereby a uniform blow-off air flow out of this ceiling member 7 is made to be formable.  In addition, in order to get rid of any deviation in the air flow to be produced by what a return air port 16 is at one side of an underfloor, the opening factor in the vent hole of an floor member 12 is made to be larger in proportion as being far from return air port 16.
