IPC: G11C11/407
Filed: 1991-03-19
Abstract: PURPOSE:To quicken a drive timing of word lines by deciding a redundancy column drive timing with the change timing of a signal for address comparison result, and a normal line drive timing with the output timing of a pre-decode signal. CONSTITUTION:At the time before the address comparison is operated, a reset signal, the inverse of R, comparison signals C1, C2, node 47, and word line 131 are in the L-level, and nodes 46, 48 are in the H-level. From this state, the signal, the inverse of R is inverted to the H-level and pMOS 29, 31 become OFF. Next, when the address inputted from the outside of a chip and a redundancy address stored in ROM 6, 7 are noncoincident, the signals C1, C2 are inverted to the H-level and an nMOS 30 becomes ON and an nMOS 33 becomes OFF, then the node 47 becomes the H-level slightly later and an nMOS 34 becomes ON. At this stage, the node 48 keeps the H-level and the line 131 keeps the L-level without being activated. Similarly, the word line 132 is also inactivated. In this case, a selection and driving of the normal line are made by a normal line selecting and driving circuit column 45.

IPC: B28B11/24
Filed: 1995-03-15
Abstract: PURPOSE: To reduce the development of dew condensation or drying and, at the same time, realize effective curing by a method wherein the curing of molded materials, which are placed on respective stacked pallets is carried out under the state that neither egress nor ingress of moisture out of the curing atmosphere surrounding the molded materials occurs and no direct contact between the wall material excluding the curing atmosphere and the surface of the molded material occurs. CONSTITUTION: Molded materials 3, each of which is obtained by kneading and molding cement mixture are received on pallets 1 so as to cure the molded material 3 placed on the stacked pallets 1 in order to obtain cement building materials. In this case, both the opened edge faces of the stacked pallets 1 are sealed with waterproof sheet so as to carry out curing under the condition that the influx of steam or the like is prevented from occurring at the curing temperature of 40 deg.C or higher. As a result, no dew condensation is recognized ands shrink deformation is small. These depends upon the remarkable reduction of the egress and ingress of moisture due to the effect of the seal applied at the open ends of the pallets 1. Accordingly, even under the condition that the curing condition is at a high temperature, and in a highly humid or dry one, in the neighborhood of the material, dew condensation is hard to develop and the hardening reaction of cement is favorable and final temperature becomes high.
