Title: Cipher communication system
Inventor: TOMOYASU KEISUKE
IPC: H04L9/08
Filed: 1989-12-05
Abstract: PURPOSE:To manage the concealment of operating key information only through a cipher communication system by transmitting and storing the operating key information of a cipher communication device for operation by ciphering it by an open key for transmitting the operating key information of a cipher communication device for a redundant spare. CONSTITUTION:An I-th cipher communication device for the operation (I is integers from 1 to N) generates the open key KEI and a secret key KDI respectively, and the cipher communication device for the redundant spare generates the open key KES and the secret key KED for transmitting the operating key information. Then, a redundancy switching monitor and control device 1 collects the open key KEI and the open key KES for transmitting the operating key information from the each cipher communication device, and transmits the open key KES for transmitting the operating key information to the cipher communication devices under the operation, and each cipher communication device for the operation having received this ciphers the secret key KDI by the open key KES for transmitting the operating key information, and transmits information EKS (KDI) obtained as the result of this to the redundancy switching monitor and control device 1. Thus, the concealment of the operating key information is managed only thorugh the cipher communication device.

Patent JP-H02168823-A (JP)
Title: Charging voltage controller
Inventor: YASUDA KOJI
IPC: H02J7/24
Filed: 1988-12-19
Abstract: PURPOSE:To prevent overcharge and over-discharge of a battery and to lengthen the service life of the battery by providing a reference voltage generating circuit for varying the reference voltage in zigzag with respect to the ambient temperature thereby maintaining the battery voltage continuously at a proper level regardless of the ambient temperature. CONSTITUTION:Battery voltage is divided through resistors 33, 34 then the divided voltage is fed to + side of a comparator 32. Since the temperature detecting diode 1 in a reference voltage generating circuit 26 has such characteristic that the voltage drops forward as the ambient temperature rises, reference voltage Vout of a buffer 25 varies in zigzag. A comparator 32 compares the reference voltage Vout with the battery voltage, and if the battery voltage is lower than the reference voltage a transistor 30 turns ON to feed current through an exciting winding 29 thus generating power from a generator 27. If the battery voltage is higher than the reference voltage, the transistor 30 is turned OFF to interrupt current supply to the exciting winding 29 thus stopping generation of power. Battery voltage is maintained at a predetermined level by repeating the operation. By such arrangement, service life of the battery is lengthened.
