Abstract: An unmanned contract system is constructed by connecting a contract processing apparatus, which is manipulated by a financial institute for processing contracts, with a contract terminal, which is manipulated by each user, via a communication line. The contract processing apparatus obtains required information for a contract from each user's cellular phone, prior to the user's operations at the contract terminal and performs a preliminary examination. The result of the preliminary examination is mapped to an MAC address of the user's cellular phone obtained as identification information and is kept in the contract processing apparatus. The contract terminal fetches the MAC address from the user's cellular phone and transmits the MAC address to the contract processing apparatus. The user is not required to write down any identification information but can utilize the result of the preliminary examination. This arrangement ensures quick conclusion of the contract.

Abstract: Signals are transmitted using light or the like in a cordless manner between a keyboard and a controller related thereto. The keyboard transmits a signal that indicates a keycode corresponding to a key to the controller in a cordless manner, and the controller sends the keycode signal back to the keyboard. The keyboard compares the transmitted keycode with the received keycode to check whether the keycode signal is correctly transmitted to the controller. When the communication is to be carried out between a plurality of keyboards and the related controllers, a device code specific to the keyboard is attached to the keycode such that the individual keyboards can be identified.

Abstract: A driving circuit uses an output transistor and a driving transformer with a secondary coil being connected to the base of the output transistor. In order to get a high speed switching circuit without thermal runaway, the storage period of the output transistor is detected. A signal supplied to a primary coil of the driving transformer, for example, a driving pulse, is controlled in response to the detected value of the storage period. By minimizing the value of the storage period, it becomes possible to minimize a fall time of the output transistor, so that a stability of the driving circuit can be maintained.

Abstract: A horizontal deflection output circuit, such as used in a TV receiver or a display device, includes a series circuit composed of a ringing preventing resistor and a one-way switching element connected in parallel with a linearity correcting coil. That one-way switching element is turned on at the beginning of a horizontal scanning period to feed a current to the ringing preventing resistor but is turned off in the vicinity of a fly-back period to block the flow of the current to the ringing preventing resistor. Thus, the power loss due to the current flowing through the ringing preventing resistor for the fly-back period can be reduced according to the present invention.

Abstract: A cascode amplifier comprises a grounded-emitter drive transistor which has a collector supplied with a bias current from a bias current source and operates in response to an input signal and a grounded-base (or grounded-gate) output transistor which has a collector supplied with a bias current from a constant voltage source, wherein the collector of the drive transistor is connected to the emitter (or source) of the output transistor. A constant current circuit is connected to the junction between the collector of the drive transistor and the emitter (or source) of the output transistor for supplying a part of the bias current applied to the drive transistor to thereby decrease the bias current of the output transistor while causing the drive transistor to be operated in the linear region. The cascode amplifier is thus imparted with a broad band frequency characteristic.
