Abstract: A brushless motor which includes an arrangement to prevent dielectric breakdown of electronic parts mounted on a control board. The breakdown is caused by a heat sink which becomes electrostatically charged. The potential at the heat sink, which contacts switching devices (for instance, FETS) of the brushless motor, is equalized with the potential at one side of a source line for a drive circuit formed on the control board that includes the switching device. As a result, when the heat sink becomes electrostatically charged, the charge at the heat sink can be discharged to the source line, thereby eliminating the above problem.

Abstract: An air cleaning apparatus for vehicles includes an ozone generator, diffusing plate, and activated charcoal filter, which are disposed sequentially from the upstream side of air flow in an air cleaning duct. The activated charcoal filter contains acid treated activated charcoal and alkali treated activated charcoal. Thus, in the air cleaning apparatus for vehicles, the ozone generator oxidizes ammonia and acetaldehyde and then absorbs and removes the products by acid activated charcoal and alkali activated charcoal. As a result, ammonia, acetaldehyde and acetic acid which are bad odor components of cigarette smoke can be removed sufficiently and effectively.

A protrusion of the lift piece and the distal end of a push rod are held by a spring seat with a specified clearance therebetween as a prelift. The adjustment of the prelift can be performed only by taking out the lift piece to be adjusted, so that the adjusting work of the prelift, accompanied with disassembly of the fuel injection nozzle becomes easy and fuel injection characteristics are improved.

Abstract: A variable capacity wobble plate compressor includes a first spring, fitted on a drive shaft between a hinge ball axially slidably fitted on the drive shaft and a thrust flange rigidly fitted on the drive shaft, for urging the hinge ball toward a cylinder block, and a second spring fitted on the drive shaft between the hinge ball and the cylinder block for urging the hinge ball toward the thrust flange. As the hinge ball is moved toward the thrust flange, a linkage connecting a drive hub slidably mounted on the hinge ball a causes an inclination of the drive hub to be increased to increase capacity of the compressor, and as the hinge ball is moved toward the cylinder block, the linkage causes the inclination of the drive hub to be decreased to decrease the capacity of the compressor. A first stopper blocks the hinge ball from moving toward the thrust flange in excess of a predetermined amount, to thereby restrict an increase in the inclination of the drive hub and set the maximum capacity of the compressor.

Abstract: In a tank aggregate body for a receiver tank that achieves vapor/liquid separation of a coolant that has been liquefied at a condenser, a primary body wall portion is formed by rolling a plate material, bonding margins are formed at the two sides continuous to the primary body wall portion, a tank primary body is constituted from the primary body wall portion by abutting the bonding margins and the opening ends of the tank primary body are closed off with caps.

Abstract: In the process steps a tentative value (m) of a deviation in a turning angle of a rotor of the stepping motor is determined each time the stepping motor runs. A cumulative amount of the tentative values (m) forms an estimated value (S) of the deviation in the turning angle of the rotor of the stepping motor. This estimated value (S) of the stepping motor. This estimated value (S) of the deviation is stored in a predetermined memory area. When an ignition switch is turned on, it is judged whether or not the estimated value (S) of the deviation thus stored until the ignition switch is turned on, exceeds a predetermined value. When it is judged that such estimated value (S) exceeds the predetermined value, an initial setting of the stepping motor is made.
