    摘要: In a read only semiconductor memory, signal lines such as data lines are subjected to an undesired parasitic capacitance which restricts the signal changing rate along the lines. The parasitic capacitance which is driven by a memory cell will become increasingly higher as the memory capacity is increased. According to the present invention, a differential sense amplifier is used to amplify the data signals which are read out of the memory cell. At the same time, a dummy cell is used to generate a reference potential which is to be referred to by the differential sense amplifier. In particular, a dummy cell arrangement is provided wherein each dummy cell includes at least two series-connected semiconductor elements to provide a predetermined dummy cell conductance to establish a reference value. Another aspect of the invention lies in the use of column switches between a common data line and data lines of the memory arrays for coupling only one data line at a time through the column switch to the sense amplifier. In addition, a built-in error-correcting-code circuit is provided which operates in conjunction with a selecting circuit so that memory cells delivering a predetermined set of data are spaced apart from one another by at least predetermined distances to reduce the likelihood of errors from immediately adjacent memory cells.

    摘要: Improvement of simplicity and durability of a stretch rod extending device and a bottom mold lifting device, equipped on a stretch blow molding machine, is achieved by applying a combination of a magnetic screw shaft and a magnetic nut member, which is able to convert rotary-linear movement smoothly without contact. The nut member and the screw shaft of the extending device 6 and lifting device 30 comprise a magnetic nut member 65, 116 and a magnetic screw shaft 66, 117, having spiral N magnetic pole and S magnetic pole alternately provided on inner peripheral surface of a cylindrical member and outer peripheral surface of a shaft at a same regular pitch. The magnetic screw shaft is inserted into the plunger 61, 115, having the magnetic nut member equipped inside with keeping required clearance so as to match the magnetic pole to oppose the magnetic nut member at the same poles each other.
