Filed: 1992-07-10
Abstract: PURPOSE:To reduce current consumption in a sense amplifier by providing an MOS Tr actuating the sense amplifier on the control terminals of respective sense amplifiers provided in word unit. CONSTITUTION:The series circuit of a (p) channel Tr 4 and an (n) channel Tr 2 is connected to the series circuit of the (p) channel Tr 3 and the (n) channel Tr 1 in parallel, and a connection part between the Trs 3, 4 is connected to power source Vc, and the connection part between the Trs 1, 2 is grounded through the Tr 5. A coincidence line 11 is connected with the connection part between the Trs 3, 1 through the Tr 9, and the connection part between the Trs 4, 2 is connected with the power source Vc through the Tr 10. Thus, since the current of the sense amplifier flows through the different circuits from each other at every word and the control terminal is independent at every sense amplifier, is not affected by other control terminal. Further, since a currant control type sense amplifier is not used, the current consumption is reduced.

IPC: H01L21/3213
Filed: 1995-07-20
Abstract: PURPOSE: To eliminate the need of alignment margin at the joint of lower layer wiring and upper layer wiring by substantially equalizing the width of lower layer wiring to that of a metal column. CONSTITUTION: First and second metal films and barrier metal films 23, 24, 25, 26 are deposited entirely on a field oxide 2. A photoresist film is applied on the entire surface and then it is removed while leaving a photoresist 27 in a region for forming a lower layer wiring. The first barrier metal film and the metal films 26, 25, 24, 23 are then subjected to selective etching using the photoresist 27 as a mask thus forming lower layer wiring patterns 13, 14. Subsequently, the photoresist 27 is removed and a photoresist 28 is patterned and used, as a mask, for etching a second barrier metal layer and the metal layers 26, 25 to form metal columns 15, 16. Since the metal column is formed by sequentially etching a metal layer where the lower layer wiring and the metal column are integrated, the lower layer wiring has substantially same structure as the metal column.  Finally, an aluminum film 29 is deposited on the entire surface and a photoresist 30 is patterned at a part for forming an upper layer wiring and then it is etched to form an upper layer wiring 16.

Title: Regeneration of cation exchange membrane
Inventor: MOMOSE TAKASHI
IPC: B01J49/00
Filed: 1983-10-04
Abstract: PURPOSE:To make it possible to regenerate a perfluorocarbon type cation exchange membrane, by treating said membrane, of which the electrolytic capacity is lowered, with a chelate reagent while converting the carboxylic group thereof to a H-type, and applying heat treatment to the treated membrane at the glass transition temp. or more thereof.

Thereafter, heat treatment is applied to the treated membrane at a temp. of the glass transition point or more of the membrane (e.g., 120-180 deg.C) in such a state that the above mentioned exchange group is converted to -COOH. Thus regenerated membrane has membrane capacity almost equal to that of the membrane before use and can be used as a diaphragm not only in electrolysis of salt but also Glauber's salt.

Abstract: PURPOSE:To avoid the deterioration and the degrading in quality due to etching step by a method wherein semiconductor thin films are grown on a stepped substrate having V type trenches by organic metal vapor depositing step or organic metal molecular beam epitaxial step. CONSTITUTION:A multielement base semiconductor thin film 2 or super-lattice layer is formed on a stepped semiconductor substrate 1 crystal having V type trenches 1a corresponding to the grating pitches by organic metal molecular beam epitaxial step or organic metal vapor depositing step. At this time, a grating structure in sectional trianglular shape is formed due to the difference between the larger growing rate in the flat part on the stepped surface and the smaller growing rate in the sidewall parts of the trenches 1a. Next, when another semiconductor thin film 3 in the different composition from that in the thin film 2 is grown on the V type trenches 1a, the gratings are filled up with the thin film 3 so as to successively form the layers from a guide layer 4 to a P type contact layer 8. Accordingly, a distribution feedback type laser structure (a) can be formed by one time semiconductor thin film depositing step.

Title: Method for rapid aging treatment of slag
Inventor: KUWAYAMA TADASHI
IPC: C04B5/00
Filed: 1991-06-29
Abstract: PURPOSE:To enable rapid aging treatment of stag by generating ultrasonic waves from an ultrasonic generator arranged in water in a state of the slag immersed in water and promoting hydrating reaction of the slag. CONSTITUTION:Slag is immersed in water. In this state, ultrasonic waves are generated from an ultrasonic generator arranged in water to promote hydrating reaction of the slag. The hydrating reaction of the slag and elution of sulfur can be completed within an extremely short time according to the aforementioned method for treatment. The reasons for it can be considered as follows. That is, when the slag is brought into contact with moisture or water, gelatinous films are formed on grain surfaces. The films function so as to inhibit the permeation of water into the interior of the grains and the hydrating reaction. If the slag, however, is immersed in water and the ultrasonic waves are made to act thereon, the films are broken by the action of the ultrasonic waves to permeate the water into the interior of the grains and promote the hydrating reaction and elution of the sulfur.
