Title: Semiconductor storage device
Inventor: UEDA YOICHI
IPC: G11C11/412
Filed: 1990-07-10
Abstract: PURPOSE:To efficiently drive inverters to reduce the power consumption by providing a second transfer gate in the connection part between the output side of a second inverter of a close loop and the input side of a first inverter. CONSTITUTION:An input driver IV3 converts the level of the input signal of an input terminal 17 and transmits it to inverters IV1 and IV2 through a transfer gate T1, and after potentials of operating points (a) and (b) of both of them are settled, low and high levels are applied to terminals 13 and 14 respectively to turn on a transfer gate T2, and simultaneously the high level is applied to a control terminal 15 to make a driver IV3 nonactive. Input data is held as the potential of the point (a) in this state. Data is written in the state in which points (a) and (c) are temporarily electrically separated from each other, that is, the output side of the input driver IV3 and that of the inverter IV2 are electrically separated from each other in this manner. Thus, the driver IV3 can have the low driving capability, and data is written without flowing an unnecessary current between the driver IV3 and the inverter IV2.

Abstract: PURPOSE:To form a planelike image surface, by increasing and decreasing the thickness of a face plate by 1/(n-1) times (n is a refractive index) a bending extent of the image surface which is generated when the face plate is a flat plate. CONSTITUTION:An incident light beam 13 by a lens forms an image at a point 8 in case when a medium is air, and is displaced by DELTAX=(N-1)X in a point 9 by a medium 12 whose refractive index is N. Accordingly, in order to correct a bent image surface, a face plate 6 is formed to a concave surface or a convex surface in accordance with a bending extent DELTAC so that it becomes such thickness as satisfied said equation. A varied portion of thickness of the face plate 6  is obtained by deriving a distance X in case when DELTAX=DELTAC, and N has been set  to a refractive index (n) of the face plate 6, in said equation. That is to say, X  becomes DELTAC/(n-1), and the thickness is varied by 1/(n-1) times a bending extent of the image surface in case when the face plate is a flat plate. In case  of bending it in the concave shape by a lens system 2, the thickness increases  as shown in figure.
