Abstract: A temperature detection circuit includes a bandgap reference voltage generation circuit, a detection output circuit, and an output conversion circuit. The bandgap reference voltage generation circuit generates a first reference voltage and causes a bias current to flow through a current path to produce a thermal voltage. The current path has a first resistor. The detection output circuit has a second resistor and causes a mirror current of the bias current to flow through the second resistor. The output conversion circuit uses a second reference voltage to convert a voltage drop across the second resistor to a predetermined output form to detect a temperature. The first and second resistors are substantially identical in temperature dependence. The second reference voltage is generated from the first reference voltage.

Abstract: A flexible printed circuit board (FPC) is disclosed which can eliminate the need for forming through holes and ensure the strength required for mounting components. The FPC has a metal foil layer formed only on one side of an insulating layer via an adhesive layer. The FPC is configured such that the insulating layer and the adhesive layer are partially removed, and the surface of the metal foil layer on the side from which the insulating layer and the adhesive layer have been removed is flattened.

Abstract: An automatic transaction system has a cellular phone of a customer and an automatic teller machine (ATM) which can directly communicate with the cellular phone by infrared communication. When the customer performs a transaction by the ATM, transaction information such as transfer information registered in the cellular phone is directly inputted to the ATM and the ATM executes a transaction process by the transaction information which was directly received. When transaction data which is used in the transaction by the ATM is inputted once, transaction time in the ATM can be shortened by the simple operation.
