Title: Analog digital converter
Inventor: SAITO SEIICHI
IPC: H03M1/60
Filed: 1987-12-25
Abstract: PURPOSE:To apply an integral number of multiplication to a low output frequency of a VF converter and to attain AD conversion with high accuracy and high resolution at a high speed by providing a frequency multiplier circuit between the VF converter and a counter circuit. CONSTITUTION:The converter consists of the VF converter 1 converting an analog signal into a pulse signal having a frequency corresponding to its voltage, the frequency multiplier circuit 2 applying an integer multiple to the frequency of the processing unit signal from the VF converter 1 and a counter circuit 7 counting the pulse number of the pulse signal outputted from the frequency multiplier circuit 2 at an interval in response to its resolution and outputting the count numeral as a digital data. Upon the reception of an output signal being a digital signal as the result of the conversion of a frequency pulse signal corresponding to the voltage being the analog signal from the VF converter 1, the frequency multiplier circuit 2 multiplies the frequency into an integral number of multiple of frequency and gives the result to the counter circuit at the post-stage. Thus, even when the total degree of the resolution depending on the counter circuit is increased, it is not required to increase the prescribed interval to count the pulse number. Thus, the AD conversion with resolution and high accuracy is attained at a high speed.

Abstract: PROBLEM TO BE SOLVED: To improve the security of the data base contents of a data base sharing system. SOLUTION: A data base processing part 12 receives information as data base contents in a plain form format from a web server 11, converts it to a cipher format by a ciphering and deciphering module 31, and writes it in a cipher format in a storage device 32. A user when using the data base sharing system 10 should be authenticated by a server-side authentication module 13 and a security management device 14 through the IC card 19 that the user bears. For the IC-card authenticated user, information in the cipher format is read out of the storage device 32 and converted to a plain format by the ciphering and deciphering module 31, and its contents are shown.

IPC: H02J7/00
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To quantitatively discriminate the service life of a lithium secondary battery so that the battery may be used for a long period as a secondary battery for backup. SOLUTION: When a voltage V of a lithium secondary battery becomes VL or lower while the battery is in a backup standby mode, charging of the battery by a constant-current charging method is started (point t3). When the voltage V of the battery charged by the constant-current charging method becomes a fully charged voltage VH, the charging method of the battery is switched to a constant-voltage charging method (point t4). When a current I of the battery charged by the constant-voltage charging method becomes a charge-completing current IL, the charging is stopped (point t5). When the voltage value of the battery becomes the value VL or lower due to self- discharge thereafter, the charging of the battery by the constant-current and constant-voltage charging methods is restarted (point t6). This charging- discharging cycle is repeated.  The service life of the battery is discriminated based on the constant-current charging time T1 and charging interval T2 of the battery.
