IPC: G06K19/07
Filed: 1988-02-16
Abstract: PURPOSE:To specify data and hour for an on-line transaction and to lighten a burden in processing for an external device by providing a storing means to store time information prepared at a clock means and a transaction result when the title device executes the on-line transaction with the clock means to prepare the time information. CONSTITUTION:When an IC card is set to terminal equipment under an on-line state, the terminal transmits an instruction signal to indicate a desire to execute the transaction to a CPU 27 for the IC card. When the CPU 27 receives the instruction signal, the CPU 27 reads date information from a second clock circuit 323. The CPU 27 receives the date information, compares and collates the date information with validity term information stored in a data memory 30, and decides the validity term. As the result, when the date information is out of the validity term, the CPU 27 transmits a message, which indicates that the date information is out of the validity term, to the terminal and completes the transaction. On the other hand, when the date information is within the validity term, the CPU 27 transmits another message, which indicates that the transaction can be executed, to the terminal, and transaction processing is started.

IPC: F04C21/00
Filed: 1983-03-01
Abstract: PURPOSE:To simplify the mechanism, reduce the leakage of compression and permit to drive the compressor with a small driving power by converting the rotary motion of a driving shaft into the oscillating motion of a piston and compressing the suction gas alternately. CONSTITUTION:When the driving shaft 8 is rotated and an oscillating cam 7 is oscillated, one of operating chambers is expanded and the operating chamber becomes vacuum, therefore, the gas is sucked into the operating chamber through a suction port 12 under opening a reed valve. When the driving shaft 8 is rotated further from a position, whereat the volume of one of the operating chambers become the maximum confining volume, into clockwise direction, the volume of one of the operating chamber is compressed and the compressed gas opens the reed valve and is discharged out of a delivery port 14. At this time, the operation chamber at the other side is expanded in the volume thereof and sucks the gas. Thus, the oscillating piston 7 is oscillated by the rotation of the driving shaft 8 and the suction and delivery motions may be effected sequentially and alternately.
