In a fin forming step, fins of heat exchangers are formed into a connected state where the fins are connected to each other via a parting portion. In a fin attaching step, the fins in the connected state are temporarily attached to the respective heat exchangers. In a fin fixing step, an integrated heat exchanger in which the fins are temporarily attached is passed through a heating oven to braze the fins to the respective heat exchangers. In a fin separating step W4, the fins in the connected state of the respective heat exchangers are separated from each other in the parting portion. Therefore, each of the heat exchangers can independently perform a heat exchanging operation without being affected by heat conduction from the other heat exchanger via the fins.

Shock absorbers of left and right front wheel suspensions and shock absorbers of left and right rear wheel suspensions each are constituted by a damping force adjustable hydraulic shock absorber provided with a frequency response unit. An actuator of a damping force variable mechanism provided to the shock absorber is driven and controlled by a controller. The controller variably adjusts the damping force between the soft side and the hard side by the damping force variable mechanism according to a vertical vibration when a vehicle body vertically vibrates at a low frequency. The controller does not adjust the damping force when the vehicle body vibrates at a higher frequency than the low frequency.

A temporary assembly device comprises a radiator tube feeder feeding a radiator tube to lower claw parts of a pair of carrier claws to have the radiator tube held on a set base, and a condenser tube feeder feeding a condenser tube to upper claw parts of the pair of carrier claws to have the condenser tube held on first protrusions of positioning guides, so that the condenser tube is disposed immediately above the radiator tube with a predetermined interval therebetween. In this manner, a first heat exchanger core and a second heat exchanger core are temporarily assembled with these tubes being stacked in two tiers.

An electromagnetic suspension system comprises a universal joint mechanism for permitting radial movement of a cylinder relative to a center yoke while preventing axial movement of the cylinder relative to the center yoke. Since the cylinder is capable of radial movement relative to the center yoke, if a lateral force acts on the cylinder, the lateral force acting on a hydraulic damper does not have any significant effect on the center yoke 17, with respect to radial movement or rocking movement thereof. Therefore, excessive sliding friction does not occur in a center-yoke dry metal and a piston-rod dry metal, thereby ensuring smooth axial relative displacement between the center yoke and an outer yoke.

A heat exchanger 1 includes a pair of tanks 2 and 3 arranged a certain distance apart from each other, a plurality of tubes 4a whose both end portions are connected with the pair of tanks 2 and 3, a long receiver tank 5 arranged along and adjacently to the tank 3 and communicatably connected with the tank 3, and a reception member 20 contained in the receiver tank 5. An upper opening end portion 13b has an opening portion at one side in a longitudinal direction of the receiver tank 5 and having a reduced diameter, and a block member 15 blocks the upper opening end portion 13b. An entire of the heat exchanger 1 except the reception member 20 and the block member 15 are integrally formed by a brazing process. The reception member 20 is inserted through the upper opening end portion 13b and arranged in the receiver tank 5 after the brazing process, and then the block member 15 is joined by brazing with the upper opening end portion 13b after the reception member 20 is inserted and arranged therein.

An air-compressing apparatus has four compressors individually supplying compressed air to a tank having a pressure sensor. The pressure sensor is connected to control circuits of the compressors. The control circuits compute times needed for the tank pressure to reach minimum and maximum pressures, respectively, of the tank by using the detected tank pressure and also using a tank pressure change value. The computed time values correspond to the consumption of compressed air. Thus, the control circuits can control the number of compressors to be operated according to the consumption of compressed air.

A method of manufacturing a heat exchanger includes processes of: arranging tubes at a predetermined pitch on a set base; inserting fins into spaces each defined between the tubes; compressing the tubes and the fins in the direction of arrangement thereof; mounting hollow headers to longitudinal ends of the tubes, each header having slits engaged with a corresponding end of the tubes; and attaching end covers to both ends of the headers, each cover closing holes which open at the corresponding end of the headers.
