摘要： An abnormality determination apparatus includes: an audio data acquisitor that acquires audio data of an apparatus to be judged for determining presence or absence of abnormality; an abnormal sound detector that detects an abnormal sound based on the audio data acquired by the audio data acquisitor; and a hardware processor that determines whether the abnormal sound is such a sound that an operation of the apparatus to be judged should be restricted based on a subsequent secular change of the abnormal sound when the abnormal sound is detected by the abnormal sound detector, and restricts the operation of the apparatus to be judged when the hardware processor determines that the abnormal sound is such a sound that the operation of the apparatus to be judged should be restricted.

摘要： An electric power supply control device comprises AC/DC converter, DC/DC converters, and an output electrical voltage monitor unit of the AC/DC converter. When output electrical voltage of the AC/DC converter increases to the first preset value P1, the AC/DC converter stops the convert. When the output electrical voltage decreases to the second preset value P2, the AC/DC converter restarts the convert. The first preset value P1 is equal to or less than the lowest value, out of the upper limit values in electrical voltage ranges in which the DC/DC converters CV1 and CV2 can work. The second preset value P2 is more than or equal to the highest value, out of the lower limit values in electrical voltage ranges in which the DC/DC converters CV1 and CV2 can work.

摘要： A recording medium conveyance device includes storage that stores a recording medium, a conveyer that takes out the recording medium stored in the storage and conveys the recording medium as a conveyed object, an ultrasonic sensor that outputs a value indicating an attenuation amount of an ultrasonic wave caused by the conveyed object and a hardware processor, wherein the hardware processor executes an overlay detection process of detecting whether the conveyed object is in an overlay state in which a gap is present based on a result of output by the ultrasonic sensor, and prevents execution of the overlay detection process with respect to a first conveyed object that is to be conveyed first by the conveyer.

摘要： A phase control device includes: at least one switching element connected to an AC power source, the switching element being capable of: turning on and off at specified timings; delivering AC power to a load upon turn-on and cutting it off upon turn-off; and keeping an on-time from the start to the end of turn-on and an off-time from the start to the end of turn-off, the on-time and off-time being variable; a timing setting portion that sets a turn-on and turn-off timing for turning on and off the switching element; a judgment portion that judges whether or not the turn-on and turn-off timing are on at a phase within a first or second phase range; and a processor that starts turning on and off the switching element at the turn-on and turn-off timing, the processor being capable of adjusting the on-time and off-time depending on the judgment result.
