Abstract: An object of the present invention is to provide a battery state monitoring circuit and a battery device which are capable of normally operating when a charger (301) is connected to an opposite polarity in error, and then correctly connected. In the case where the charger (301) is connected to the opposite polarity in error and then correctly connected, a logic circuit (305) does not output a power-down signal that powers down the respective circuits to the respective circuits by the aid of a power-down preventing circuit (110). As a result, the battery device normally operates without falling into the power-down state.

Abstract: A superconducting radiometry apparatus has a micro-calorie meter that detects an energy of a radiant ray as a temperature change. A signal detection mechanism detects an electric current flowing to the micro-calorie meter. A heat addition device adds a quantity of heat to the micro-calorie meter. A peak value monitor measures, in synchronization with the addition of the quantity of heat to the micro-calorie meter, a peak value of an output voltage corresponding to an output signal from the signal detection mechanism. An energy correction device corrects, on the basis of an output from the peak value monitor, an energy value so as to become a peak value corresponding to the quantity of heat added to the micro-calorie meter.

Abstract: Provided is a thermal activation device capable of preventing a heat-sensitive adhesive sheet from being partially excessively heated, keeping a short distance between a contact between a thermal head and a platen roller, and a discharge port, and preventing a structure of the thermal activation device from being complicated and a size thereof from increasing. While a heat-sensitive adhesive sheet (2) is transported along a transport path (15) through rotations of insertion rollers (3) and a platen roller (5), a heat-generating portion (4a) of the thermal head (4) is caused to generate heat, thereby thermally activating a heat-sensitive adhesive layer of the heat-sensitive adhesive sheet (2). When a trailing edge of the heat-sensitive adhesive sheet (2) reaches a position where the trailing edge thereof is not in contact with the platen roller (5), a transporting force is not transmitted to the heat-sensitive adhesive sheet (2), thereby stopping transportation thereof.

Abstract: To restrain a communicatable distance from being shortened even when a power source voltage is lowered. A heart beat signal transmission control portion controls a resonance starting oscillation portion to output a start signal in synchronism with a heart beat signal detected by a heart beat signal detecting portion and controls a resonance starting portion to output a biometric information signal in response to the start signal. An element switching portion receives a signal representing a voltage supplied from a battery portion from a voltage detecting portion and instructs the resonance starting oscillation portion to set the start signal to a period in correspondence therewith. The resonance starting oscillation portion outputs the start signal by a period in correspondence with instruction of the element switching portion.
