Filed: 1991-09-26
Abstract: PURPOSE:To improve the data recovery function by providing an edge detection means, a counter and a conversion table to the recovery circuit and selecting one conversion table among plural conversion tables. CONSTITUTION:DFF 11, 12 and a AND gate 13 generate a pulse by one period of a high frequency clock at the rise of a binarizing signal and a pulse via a gate 13 is given to a counter 14 and an output Q3 is outputted to a 3rd DFF 17 as a bit clock signal. The binarizing signal and the high frequency clock are inputted to a binarizing signal normalizing circuit 16, which generates a signal going to logical 1 at a leading edge of the binarizing signal and going to logical 0 at the fall of the bit clock signal and the signal is outputted to an FF 17. A data extract output is outputted from the FF 17. In this case, the data loaded from a ROM 15 to a counter 14 are switched and the data are effectively recovered.

Title: Sales data processor
Inventor: MATSUI MAKOTO
IPC: G07G1/14
Filed: 1990-09-20
Abstract: PURPOSE:To shorten time required for system startup in a sales data processing by making a host controller automatically carry out the down line loading (DLL) processing of set data for a terminal only when the set data is destroyed by the DLL processing in the memory section of the terminal. CONSTITUTION:When turning on each terminal 11-13 in order to start up a sales data processing, it can be judged whether or not set data is destroyed by the DLL processing in the memory section of the terminal. Further, from a terminal where set data is not destroyed, a request for treating the DLL is not issued to the host controller 2, but the request for DLL is issued from only a terminal where set data has been destroyed. On the other hand, the host controller 2 automatically executes the DLL processing of predetermined data for only a terminal 11-13 that issued the request for DLL treatment. Accordingly, if only a terminal 11-13 where the content of memory was destroyed by DLL processing due to hardware or software failure or the like automatically undergoes DLL processing by the host controller 2 to start up the system. Thereby, the time taken for starting up the system can be shortened.

IPC: G11C11/22
Filed: 1989-09-25
Abstract: PURPOSE:To prevent the crosstalk at the time of reading out and to allow the non-destructive reproducing of data by stopping the impression of the voltage before the inversion polarization area generated by the impression of a reading out voltage grows and identifying the polarity of residual polarization from the value of the currents flowing in 1st and 2nd band-shaped electrodes. CONSTITUTION:The voltage is impressed to the 1st band-shaped electrodes 17, 18 positioned above and below the ferroelectric film formed with the residual polarization. The voltage impression is stopped before the inversion polarization formed in the ferroelectric film by the voltage impression grows to the size at which the polarization remains in the film even after the impressed voltage is removed. The currents flowing in the 1st and 2nd band-shaped electrodes 17, 18 are subjected to current-voltage conversion by an amplifier 24, by which the currents are amplified. The amplified currents are inputted to a comparator circuit 26 which discriminates the polarity of the recorded residual polarization, by which the binary data is reproduced. The loss of the data by the crosstalk at the time of reading out is prevented in this way and the non-destructive reading out of the recorded data is executed.
