Title: Defect own display type memory element
Inventor: TAGAMI MASATERU
IPC: G11C29/04
Filed: 1980-12-29
Abstract: PURPOSE:To ensure the easy relief for a memory element having a partial defect, by delivering the existence of the defect at the moment when a row address including the defective memory cell is selected. CONSTITUTION:Row decoder outputs RO and R127 are connected at their edges to the gates of transistors QO and Q127 respectively. The source sides of the transistors are connected in common and then to the drain of QR of the transistor as well as to an output RD via transistors QA and QB. When the RAS input is applied and the row decoder output Rx is selected, the transistor Qx is turned  on to discharge the electric charge stored in a capacitor CR. In case a memory cell RmCm has a defect and the row address decoder output Rm is selected, the electric charge is charged to be kept as it is with the transistor QA turned on.  Thus the output RD is set at a low level.

Filed: 1980-12-29
Abstract: PURPOSE:To reduce waveform distortion and a peak by avoiding the overlap of the current conduction time of each load as much as possible, by repeatedly turning on and off the same AC power source to at least two loads with different phases. CONSTITUTION:When an AC voltage is applied from one AC power source to loads 1-3, a phase distributor PD supplies an ON origin signal or an OFF origin signal to power controllers PC1-PC3 for the loads. For example, when voltages of the front, intermediate and rear parts of a half wave are applied to the loads 1, 2 and 3 respectively, the PC1 is supplied with a zero-cross pulse as an ON indication signal, and the PC2 is supplied with a pulse having a prescribed time limit while the zero-cross pulse is regarded as an origin; and they are turned off under the phase control of the controllers PC1 and PC2. The controller PC3, on the other hand, turns on through its phase control, and an ON-OFF means SW3 uses a thyristor which turns off automatically at the zero-cross point of an alternating current. For turning-off operation at a point other than the zero-cross point, a transistor switching circuit, etc., is used.
