Abstract: In an apparatus, a gas containing CH4 and CO2 is supplied from a first supply unit to a synthetic gas production unit which generates a synthetic gas containing CO and H2 while heating a first catalytic structure; the synthetic gas is supplied to a gas production unit which generates a lower olefin-containing gas including propylene while heating a second catalytic structure; and a detection unit detects propylene discharged from the gas production unit. The first catalytic structure includes first supports having a porous structure and a first metal fine particle that is present in first channels of the first supports. The second catalyst structure includes second supports having a porous structure and a second metal fine particle in the second supports. The second supports have a second channels, a portion of which have an average inner diameter of 0.95 nm or less.

Abstract: A front imaging portion captures the front side of a vehicle. A rear imaging portion captures the interior or the rear side of the vehicle. A casing houses the front imaging portion and the rear imaging portion. A heat sink is located between the front imaging portion and the rear imaging portion in the casing to radiate heat inside the casing. A fixing portion is located on the outer surface of the casing and between a first end and a second end of the heat sink and separated from the heat sink to fix the casing to the vehicle. An intake is located adjacent to the fixing portion at the first end to be open toward the heat sink. An outlet is located adjacent to the fixing portion at the second end to be open toward the heat sink while facing the intake with the fixing portion interposed therebetween.

Abstract: A car obstacle monitoring system which will not erroneously detect a distant obstacle as an obstacle around a car and can avoid an erroneous detection by relatively simple control even though it is arranged so as to emit ultrasonic waves of a single frequency. A control circuit 12 controls a right sonar 1, a left sonar 4 and center sonars 2 and 3 provided on the right side, on the left side and at the center of a car 5, respectively. The control circuit 12 has a timing element and a discriminating element. The timing element generates three emission modes including a first emission mode in which the right sonar 1 and the sonar 3 emit ultrasonic waves in synchronism, a second emission mode in which the left sonar 4 and the center sonar 2 emit ultrasonic waves in synchronism, and a third emission mode in which the right sonar 1 and the left sonar 4 emit ultrasonic waves in synchronism repeatedly without overlapping each other.

Abstract: This invention provides an icing preventive device for a supersonic wave transmitting and receiving unit for a vehicle which is composed of a timing device for outputting a timing signal, a supersonic wave transmitting and receiving device for transmitting a supersonic wave signal and receiving a reflected wave in response to the timing signal, a received signal processing device for amplifying the received signal caused by the reflected wave and processing the waveform of the amplified signal, a control device for controlling a vehicle load in response to the received signal of which waveform is processed, a temperature sensing device for sensing a temperature outside the vehicle, a heater operating device for energizing and heating the heater in response to both decrease in the temperature outside the vehicle and a level of the received signal of the reflected wave, and a heater arranged in the supersonic wave transmitting and receiving device, and further the present invention discloses the technology of t
