Abstract: A medium handling device includes a storage means that stores a single or plural medium recognition reference information, a recognition means that uses the medium recognition reference information to recognize a state of a target medium, and a setting means that, when medium recognition reference information that is new and authentication information corresponding to the new medium recognition reference information are stored in the storage means, sets use of the new medium recognition reference information as either valid or invalid. When the setting means has set valid, the recognition means uses the corresponding new medium recognition reference information to recognize a state of the medium.

Abstract: An entry device is provided with a plural number of operation keys and a temperature changing unit. The operation keys can be operated by pressing by a fingertip of a hand touching respective operation surfaces thereof, and are used for entry of an authentication character string. When the authentication character string is to be entered, the temperature changing unit changes temperatures of the operation surfaces of the plural operation keys to be substantially equal.

Abstract: A plurality of individually corresponding heaters and temperature sensors are provided along with a plurality of a PID control means. An average temperature/gradient temperature calculating means calculates the average temperatures of the temperatures measured by the temperature sensors and the gradient temperatures based on the measured temperatures. Each of the PID control means outputs an operation signal so that the average temperatures or gradient temperatures may be made equal to the desired values. A distributing means distributes the operation signal from each of the PID control means to each heater so that control by the PID control means may produce no effect on the control of the other PID control means.

Abstract: A power source apparatus with a saving in wiring, large noise immunity and an additional function is achieved by connecting AC input bus lines (Vin+), (Vin?), DC output bus lines (Vo+), (Vo?) and a current balance signal bus line (CB) for connecting first, second, third power source units 1, 2, 3 through connectors to form a module power source and connecting an additional function unit 4 for adding a predetermined additional function to the module power source using the bus lines to this module power source through a connector.

Abstract: A power source apparatus with a saving in wiring, large noise immunity and an additional function is achieved by connecting AC input bus lines (Vin+), (Vin−), DC output bus lines (Vo+), (Vo−) and a current balance signal bus line (CB) for connecting first, second, third power source units 1, 2, 3 through connectors to form a module power source and connecting an additional function unit 4 for adding a predetermined additional function to the module power source using the bus lines to this module power source through a connector.

Abstract: The invention has a first series circuit consisting of a capacitor and a diode and a second series circuit consisting of a coil and a diode, the first series circuit is connected in parallel to the commutating diode in a state that the capacitor is connected to a choke coil side in the commutating diode, and the second series circuit is connected between a connecting portion of the capacitor and the diode in the first series circuit and a commutating diode non-connecting side in the choke coil.

Abstract: A power supply module includes a plurality of power supply modules. One of the power supply units is designated as a master power supply unit. Other power supply units are handled as expansion power supply units. The power supply modules can be connected in parallel on a DIN rail so that the master power supply unit may supply an external AC voltage to the expansion power supply units. When a desired power supply capacity exceeds a power supply capacity of the master power supply unit, an expansion power supply unit is connected in parallel with the master power supply unit in order to increase the power supply capacity.
