Abstract: A wireless remote control radio-transmits a vehicle height adjusting signal tagged with a remote control identification code in order to improve vehicle height adjustment operability in a vehicle such as a truck. The remote control identification code is pre-registered in a receiver, which, upon receipt of the vehicle height adjusting signal tagged with the remote control identification code, takes in the vehicle height adjusting signal. According to information contained in the received vehicle height adjusting signal, an air suspension ECU controls the supply and discharge of compressed air for air springs to adjust the vehicle height. When an emergency operation switch is operated, the vehicle height adjusting signal from the wireless remote control is disabled, and vehicle height adjustment is preferentially made based on a switching signal from the emergency operation switch.

Abstract: A flame retardant composition includes, as essential components having two specified types of phosphate compounds; silicon dioxide or metal oxides; and at least one member selected from among higher aliphatic carboxylic acids, metal salts of higher aliphatic carboxylic acid, higher fatty acid amide compounds, and esters between mono- or polyhydric alcohols and higher aliphatic carboxylic acids. This flame retarder composition is free from secondary agglomeration, and does not need incorporation of a halogenated flame retarder that when blended in a synthetic resin, releases harmful gas at combustion. The flame retardant composition enables imparting flame retardant properties to synthetic resins with the use of a small amount of flame retarder.

Abstract: To improve operability for vehicle height adjustment, while ensuring safety, in a vehicle such as a truck, a wireless remote control radio-transmits a vehicle height adjusting signal tagged with a remote control identification code. The remote control identification code is preregistered in a receiver, which, upon receipt of the vehicle height adjusting signal tagged with the remote control identification code, takes in the vehicle height adjusting signal. According to information contained in the received vehicle height adjusting signal, an air suspension ECU controls supply and discharge of compressed air for air springs to adjust the vehicle height. When an emergency operation switch is operated, the vehicle height adjusting signal from the wireless remote control is disabled, and vehicle height adjustment is preferentially made based on a switching signal from the emergency operation switch.
