Title: Active restore circuit
Inventor: YOMO MICHIHARU
IPC: G11C11/409
Filed: 1985-12-24
Abstract: PURPOSE:To prevent the load of an active restore drive signal from being increased by providing a means boosting an active restore drive signal fed to a drain of the 3rd transistor (TR) and the 4th TR to the 1st power supply voltage or over. CONSTITUTION:When the level of a data line 1 goes to a high level and a data line 2 reaches a low level (OV) by the operation of sense amplifier, a TR Q6 is conductive, the level of a node N4 goes to OV, and the TR Q4 is cut off. When the level of a line phiQ is boosted to Vcc+alpha, the level phiQ is transferred to a node N1 through the TR Q3 being in the conductive state. Since the node N3 is charged up preliminarily to the Vcc level in this case, the boot strap effect of the TR Q3 is sufficient and the potential of the phiQ of Vcc+alpha is transferred completely to the node N1, resulting that the potential of the data line 1 is boosted to the Vcc level. Thus, the load of the drive signal is minimized and the increase in the current consumption and noise in the active restore circuit is prevented.

Inventor: IWATA KIYOTERU
IPC: G06Q20/10
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To shorten the door-to-door delivery time of electronic information by transferring the ciphered electronic information to an electronic information purchase terminal from an electronic information management device in parallel to execution of both authentication and crediting processes. SOLUTION: This electronic information management device 2 receives a purchase request from an electronic information purchase terminal 1 which purchases the ciphered electronic information. Then the device 2 requests an authenticating/crediting device 5 to execute the authentication and crediting processes. Thus, the device 5 executes both authentication and crediting processes in response to the request of the device 2. At the same time, the transfer of electronic information is started to the terminal 1 in parallel to the authentication and crediting processes. If these two processes are affirmative, a cipher cancel key is transmitted after the transfer of electronic information. As a result, the processing time can be shortened for the transaction of electronic information.

Filed: 1994-11-28
Abstract: PURPOSE: To fix the issue level of an alarm regardlessly of the increase/decrease of a mark rate by inputting a voltage correlated to the mark rate to a compara tor circuit for transmitting an alarm signal as a threshold value. CONSTITUTION: The voltage of the peak value correlation of a timing component is inputted from a peak detection circuit 16 to a comparator circuit 18 as a peak detecting signal P. Besides, the voltage of mark rate correlation is inputted from a mark rate detection circuit 17 to the circuit 18 as a mark rate detecting signal M. At the circuit 18, this mark rate detecting signal M is defined as the threshold value and compared with the peak detecting signal P. When the peak detecting signal P is lower than the threshold value M, an alarm signal A is transmitted to the outside, a reset signal R is transmitted to an identification reproducing part 13 and a timing extraction part 14 at a reproduction repeater 10, and a data signal D and a clock signal C are reset.  Therefore, a threshold voltage is controlled corresponding to the change of the mark rate and the issue level of the alarm is fixed regardlessly of the change in the mark rate.
