Abstract:
A method of manufacturing a semiconductor memory device according to the embodiment includes: forming a first stacked-structure; forming a first stripe part and a first hook part at the first stacked-structure; forming a second stacked-structure on the first stacked-structure; forming a second stripe part and a second hook part at the second stacked-structure; repeating the above-described four steps for a certain number of times; and forming a contact plug contacting the first or second hook parts. The etching is conducted to remove the first stacked-structure in a region at which the second hook part is to be formed in the second stacked-structure higher than the first stacked-structure by one layer. The etching is conducted to remove the second stacked-structure in a region at which the first hook part is to be formed in the first stacked-structure higher than the second stacked-structure by one layer.
Abstract:
A semiconductor memory device includes a memory cell array configured as an arrangement of memory cells each arranged between a first line and a second line and each including a variable resistor. A control circuit controls a voltage applied to the first line or the second line. A current limiting circuit limits a current flowing through the first line or the second line to a certain upper limit or lower. In a case where a writing operation or an erasing operation to a memory cell is implemented a plural number of times repeatedly, the current limiting circuit sets the upper limit in the writing operation or erasing operation of the p-th time higher than the upper limit in the writing operation or erasing operation of the q-th time (q

Abstract:
A method and system for determining the bonding quality of a bonded area of a flapped boxmaking blank in a boxmaking apparatus at an assembling station of a production line, where opposite end portions of the blank are bonded together with confronting edges of companion end flaps defining a required gap, in terms of the outline of the gap. The quality determination is accomplished by irradiating sheetlike light onto the bonded area across the gap, forming an image of the irradiated light as a light image line composed of discrete segments which are arranged along a reference line for the flap portions and include at least one line segment located off the reference line, computing a ratio of a length of the off-line segment to the entire length of the light image line to obtain a width of the gap, and comparing the width of the gap with a preset reference value.
Abstract:
A system for transmitting still picture data between a first still picture transmitter with a display device and a keyboard disposed on one panel, and a second still picture transmitter with a display device and a keyboard disposed separately. The second still picture transmitter comprises memory means for storing a plurality of still picture files with individual file names, and transfer means for transmitting or receiving the still pictures and the file names. The first still picture transmitter further comprises control means for reading out the data of the file names from the memory means via the transfer means of the second still picture transmitter.
Abstract:
Multilayered ceramic substrates having Cu electrode patterns in or on ceramic-glass insulating layers which consist essentially of Al.sub.2 O.sub.3, SiO.sub.2, B.sub.2 O.sub.3, Na.sub.2 O, K.sub.2 O, CaO, MgO and PbO. The methods for manufacturing the substrate comprises thermally treating a laminate of alternately superimposing ceramic-glass insulating layers and CuO-based electrode layers of desired patterns in air or in a molecular oxygen-containing atmosphere to eliminate organic binders from the laminates by burning out, reducing the CuO into metallic Cu at low temperatures in an atmosphere containing hydrogen, and firing the thus reduced laminate in an inert gas such as nitrogen. The firing is effected at 850.degree. to 950.degree. C. The multilayered ceramic substrate may also be obtained by forming ceramic-glass insulating layers and CuO-based electrode layers alternately on a sintered ceramic support, followed by the thermal treatment, reduction and firing set forth above.
