Patent JP-H0398461-A (JP)
Title: Conduction controller for inductive load
Inventor: BAN ITSUKI
IPC: H02P7/285
Filed: 1989-09-11
Abstract: PURPOSE:To quicken the rise-up of a conduction current by the high voltage of a capacitor by a method wherein an accumulated energy is converted into the electrostatic energy of the small-capacitance capacitor to reduce the conduction current quickly while a switching element is conducted when the conduction current has been reduced to a predetermined value. CONSTITUTION:The accumulated energy of a load 1 tends to circulate to the positive pole 2a of a power source by diodes 4a, 4b, however, the circulation is precluded by a diode 6 and a capacitor 5 is charged. The capacitance of the capacitor 5 is small and, therefore, the voltage thereof is increased and an exciting current is reduced quickly. When the exciting current is reduced to a predetermined value, an output is returned to a high level due to the hysteresis characteristics of an operational amplifier 11. Accordingly, transistors 3a, 3b are conducted, the exciting current is increased suddenly and is increased further by a power source voltage nextly. When the exciting current has exceeded a reference voltage, transistors 3a, 3b in a chopper circuit become non-conductive again.

Title: Transaction system
Inventor: AKIYAMA HARUOMI
IPC: G06Q40/02
Filed: 1982-12-28
Abstract: PURPOSE:To ensure a safe and assured transaction by storing a temporary secret number into an IC chip memory on an IC card to enable to have a request only for a prescribed transaction without showing the basic secret number of the IC card. CONSTITUTION:A temporary secret number is stored into the memory of an IC chip 9 on an IC card 8 by a data input device. When a deputy puts the card 8 into a transaction device 20, the device 20 reads the transaction account data, the basic secret number and the temporary secret number stored in the memory of the card 8 and delivers them to a main control part 50. A secret number equal to the temporary secret number supplied from an IC chip read/write part is applied through keyboards 25 and 26. Then the transaction is carried out when the coincidence is obtained between both secret numbers. Thus it is possible to have a request only for a prescribed transaction without informing the basic secret number.

Title: Low saturated power source circuit
Inventor: ITO HISASHI
IPC: H03F3/45
Filed: 1996-08-16
Abstract: PROBLEM TO BE SOLVED: To provide a power source circuit using a bipolar transistor suppressing a reactive current when a power source voltage is low, by negatively feedback-controlling the voltage of the emitter collector of an output PNP transistor by first or second deviation amplifiers so as to maintain to be not less than a reference potential difference. SOLUTION: When a power source voltage is boosted, the base current of the output PNP transistor 6 is suppressed through a driving NPN transistor 5 by the negative feedback output of the first deviation amplifier 4 to maintain an output voltage to be a set voltage. In addition, as a potential difference between the power source voltage and the output voltage is not less than the reference potential difference in this range, the second deviation amplifier 9 controls an NPN transistor 31 to be in a disconnected state and the transistor 5 is controlled exclusively by the amplifier 4. Thereby, voltage between an emitter and a collector is negatively feedback-controlled by the amplifier 9 or 4 without regard to the value of the power source voltage and maintained to be not less than the reference potential difference.
