Abstract: A portable electronic device includes a biometric information obtaining unit and an authentication information generating unit. The biometric information obtaining unit obtains biometric information that represents a physical feature of a user of the portable electronic device. The authentication information generating unit generates authentication information that is numerical information for authentication of the user having a predetermined number of digits, based on the biometric information that has been obtained by the biometric information obtaining unit.

Abstract: A malfunction diagnosis apparatus includes: a first temperature detector; a second temperature detector that is placed in a different location from where the first temperature detector is placed; a difference value calculation device calculates a difference value between a detection value from the first temperature detector and a detection value from the second temperature detector; a mapping device carries out mapping of the difference value and calculates a correction value using the frequency of the difference value; a malfunction diagnosis device diagnoses whether or not there is a malfunction in the first temperature detector and the second temperature detector; and a recovery device calculates, as a detection value of the first or second temperature detector judged to be malfunctioning, a value by adding the correction value to a detection value from the first or second temperature detector judged not to be malfunctioning.

Abstract: To provide a broadcast receiving apparatus including an AM detector, an AM noise detector, an FM detector, an FM noise detector and a noise determining unit. The AM detector performs AM detection on an IF signal in airwaves received by a receiving antenna that receives incoming airwaves to acquire an AM detection signal. The AM noise detector detects noise components in the AM detection signal. The FM detector performs FM detection on the IF signal to acquire an FM detection signal. The FM noise detector detects noise components in the FM detection signal. The noise determining unit determines a noise status of a broadcast signal based on detection results acquired by the AM noise detector and the FM noise detector.

Abstract: To provide a broadcast receiving apparatus including an AM detector, an AM noise detector, an FM detector, an FM noise-level detector, and a threshold control unit. The AM detector performs AM detection on a broadcast signal in airwaves received by a receiving antenna that receives incoming airwaves to acquire an AM detection signal. The AM noise detector detects a signal portion, in which the AM detection signal exceeds an AM noise threshold, as an AM noise component. The FM detector performs FM detection on the broadcast signal to acquire an FM detection signal. The FM noise-level detector detects an FM noise level of the FM detection signal. When the FM noise-level detector detects the FM noise level of the FM detection signal, the threshold control unit changes setting of the AM noise threshold in the AM noise detector based on the FM noise level of the FM detection signal.

Abstract: A process for producing a carotenoid emulsion characterized by passing a suspension of a carotenoid in toluene through a heated pipe at such a rate as to result in a residence time of 10 to 600 seconds to thereby heat the suspension to 50 to 120° C. and dissolve the carotenoid, immediately mixing the resultant solution with water having a temperature of 5 to 60° C. in the presence of an emulsifying agent to form an emulsion, and distilling off the toluene under vacuum. By the process, an emulsion containing a carotenoid as an active ingredient can be easily and industrially advantageously produced with satisfactory productivity while maintaining a high proportion of wholly trans molecules in the carotenoid.
