IPC: G06Q40/00
Filed: 1982-06-23
Abstract: PURPOSE:To shorten the processing time of continuous transactions, by inserting a bankbook for the next transaction and reading the magnetic strap area of the bankbook even though another bankbook is previously inserted and under transaction. CONSTITUTION:A bank book inserted through a bankbook inserting slit 11 by a user is detected by a sensor. This detection is reported to a control part 26. The part 26 actuates a reading roll driving part 18, and the magnetic data written to the magnetic strap area of a bankbook is read by a reading head. Then a suction roll driving part 19 is actuated when the inserted bankbook is normal. Thus the bankbook is sucked up to the position of a printing head 15. At this stage the part 26 reads the magnetic data written to the magnetic strap of the bankbook by a reading head 13 when another bankbook is inserted to the slit 11. Therefore the magnetic data is read during a preceding transaction to prepare for the next transaction.

Abstract: PURPOSE:To save the power consumption of an input circuit by making the current flowing through an external contact circuit flow in every n-circuit of the input circuit in a time division and sampling an input data synchronously with the signal. CONSTITUTION:A pulse generated in an oscillator 24 is inputted in 4-bit counter 25, and a decoder driver circuit 26 turns on a semiconductor switching circuit 22a and one of switches 22 to introduce a signal through an external contact 21 into an input receiving photocoupler 23. The signal is sampled in a shift register 27 by a pulse from an oscillator 24. The information of a register 27 is set up in a latch circuit 28 by a carry signal from the counter 25. Namely, the signal of the contact 21 is set up in the circuit 28 in every n (=16) bits. When requiring external contact information, a computer can open a gate circuit 29 and read out the data in the circuit 28. Since the current flowing through the external contact 21 is multiplexed by the circuits 22 and 22a, it is possible to control the current flow within one circuit at maximum, so that power saving design is made available.

Title: Communication device
Inventor: KOIDE KOJI
IPC: H04B1/04
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To surely transmit data by repeating re-transmission of transmission data with a transmission power stepwise increased in the case that a transmitter side device receives no reception end code within a prescribed time after the transmission of the transmission data. SOLUTION: A control section 1 instructs a controller 5 that is a set transmission means of a setting power stored in a transmission parameter memory 4. The controller 5 controls the transmission means 6 on the basis of this signal. When transmission of data is finished, a transmitter side reaches a reception mode to receive a reception end code that is sent from a receiver side. In the case that the transmitter side cannot receive the reception end code from the receiver side within to prescribed time, the transmitter side increases the present transmission power of the transmission means 6 by one step. The processing above is repeated until the transmitter side receives the reception end code after the data transmission.  It is not required for a user to set the transmission power and the transmission means based on a transmission distance or the like, and they are automatically and surely be set.

Abstract: PURPOSE:To obtain an FM modulating circuit realized with a small-scale circuit constitution by inputting a triangular wave voltage of the circuit to a voltage comparator which compares this voltage with a reference voltage, and feeding back negatively the output of this voltage comparator through a low-pass filter and an amplifier so that it attains to the reference voltage. CONSTITUTION:When an analog signal is inputted to a transistor Tr1, a capacitor C is charged; and when the charged voltage is higher than a threshold voltage VS, the electric charge of the capacitor C is discharged by the output of a voltage comparator 1. The triangular wave generated between both ends of the capacitor C is inputted to a voltage comparator 2, and the output is allowed to pass a low-pass filter 3 and is amplified by an amplifier 4 to obtain a voltage having the center level of the triangular wave shown by a figure B, and this voltage is fed back negatively as the threshold of the voltage comparator 2. Since the threshold level is always the center level of the triangular wave by this negative feedback, pulses of a pulsed FM signal of the output of the voltage comparator 2 is the same in width, and an average value is not varied, and consequently base band components disappear, and an FM signal symmetrical to the center frequency of the spectrum of the pulses FM signal is outputted.
