Abstract: The vehicle cabin temperature control device comprises an air conditioning device based on a refrigeration cycle including a compressor driven by an electric motor, and including an air blowing port for blowing conditioned air into a cabin of a vehicle, and an air blowing device configured to blow conditioned air to an occupant seated on a seat and consuming less electric power than the air conditioning device, and a control unit that activates the air blowing device for a predetermined time period upon startup of the air conditioning device.

Abstract: An illuminator includes: a light emitter including a light-emitting diode; a temperature sensor configured to detect a current temperature of the light emitter; and an illumination controller configured to adjust a drive voltage being supplied to the light emitter in accordance with the current temperature. The illumination controller includes a reference temperature storage in which a reference temperature is stored in advance and is configured to adjust the drive voltage by detecting the current temperature from the temperature sensor on a constant time cycle and comparing the current temperature with the reference temperature.

Abstract: A synchronous recording system is configured with a first seismograph and a second seismograph. The first seismograph includes a sensor, a GPS receiver, a data buffer, and a synchronous information transmission program that transmits synchronous information to the second seismograph, the information designating recording start time. The second seismograph includes a sensor, a GPS receiver, a data buffer, a recorder, a synchronous information reception program that receives the synchronous information, and a recording control program that starts, based on the synchronous information, recording in the recorder of oscillation data, which is recorded in the data buffer, from the designated recording start time.
