IPC: G04C23/14
Filed: 1978-09-12
Abstract: PURPOSE:To ring alarm sounds once a day at a desired time by connecting a 24 hour converting circuit and an alarm sound time setting switch between a mechanical switch and an alarm sound signal generating circuit. CONSTITUTION:In case the alarm sounds are to be generated within 12 hours, an alarm sound time setting switch 27 is truned on. When a set time is set by a time setting mechanism, a mechanical switch 15 is turned on so that the potential at a point B assumes a level H. The signals at the level H are fed to a D-type FF 20 so that they are subjected to frequency devision. On the other hand, the signals at the level H are fed from the switch 27 to an AND circuit 22, and the signals at a point E are generated from the circuit 22. On the other hand, since an circuit 23 is closed, the sgnals at the point E are fed out of an OR circuit 26. Since the AND circuit 26 has its other input supplied with the signals at the point C, there are generated at an output G the signals which will generate sounds within l2 hours. In case the alarm sounds are to be rung after 12 hours, if the switch 27 is turned off the input of the circuit 26 is supplied with the signals, which are inverted from those at the poing E, so that the sounds are generated after 12 hours.

Title: Semiconductor storage device
Inventor: TAKAISHI IZUMI
IPC: H01L27/10
Filed: 1984-05-30
Abstract: PURPOSE:To output only data corresponding to an address directly in a floating state when a chip is selected, and to perform stable operation by driving an output buffer circuit in synchronism with a sence amplifier. CONSTITUTION:When data from a memory cell 2 is inputted to the sense amplifier 7 and either of two outputs E of the sense amplifier falls to an L level at time, T, the output of an AND circuit 9 which is at an H level so far falls to the L level and an output-enable signal OE also falls to the L level. Consequently, the output buffer circuit 8 begins to operate, but the data of the memory cell 2 is already inputted to the output buffer circuit 8 through the sence samplifier 7, so no false data is outputted and normal data is outputted directly in the floating state.
