IPC: G11C11/401
Filed: 1988-01-05
Abstract: In a semiconductor memory device with normal word lines and spare word lines, a partial decoder (PD1 - PD4) receives and decodes a predetermined two of the bit signals of the original logic levels of an address signal, and two of the bit signals of the complementary logic levels, which correspond to the predetermined two bit signals, and outputs different signal combinations of the predetermined two bit signals and the two corresponding bit signals. A spare word line selecting circuit (SC1 - SC4) receives the different signals and selects one of the different signals in order to select a spare word line which corresponds to a normal word line of which a defective cell is connected. The partial decoder may be used for both the normal word line selection and the selection of spare word lines. With a device constructed in such a manner, bit signals of an address signal are not directly input to the spare word line selecting circuit, but rather signals of different bit signal combinations are input to it. The spare word line selecting circuit merely selects signals of different combinations, and does not need the partial decoding of the address signal. Therefore, the chip area required for wiring may be remarkably reduced when compared with the conventional memory device.

Abstract: An electrostrictive device having a sealing structure of an electrostrict element has a tubular member for housing the electrostrictive element. A pair of lid members are attached to the top and bottom surfaces of the electrostrictive element. The lid members are flexibly combined to the tubular member by using an elastic sealing means such as silicone resin and O-ring. The side surfaces of the electrostrictive element is spaced apart from the inner wall of the tubular member due to the lid members. The foregoing structure enables a reliable hermetic seal without impairing the mechanical displacement of the electrostrictive element.

Abstract: A tuyere is disclosed which is adapted for the injection of gases into a metallurgical vessel. The tuyere includes inner and outer concentric tubes having a radial separation therebetween which defines an annular gap. In use, one gas such as an oxygen mixture flows through the center of the inner tube, and a second normally inert gas flows through the annular gap between the two tubes. In order to provided a closely predetermined and predictable gas flow rate through the annular gap, an annular groove is formed in the wall of the outer tube which forms an annular restriction in the gap, and the extent of the restriction may be calibrated so as to provide a closely predetermined gas flow rate therethrough when in use. An annular groove may also be formed in the wall of the inner tube to provide a predetermined restriction in the gas flowing through the inner tube. The restrictions are positioned adjacent the respective inlet ends of the tubes, so that erosion of the outlet ends does not appreciably effect the gas flow rates through the inner tube and annular gap. A calibration process is also disclosed, and which assures that all of the tuyeres to be used in a common metallurgical vessel have a closely similar gas flow rate through the annular gap.
