Abstract: When producing a graft modified polyolefin by melting and kneading a polyolefin, a radical-polymerizable monomer and a radical-polymerization initiator, the producing efficiency is improved. The grafting reaction is effected by feeding the melted polyolefin containing either one of said radical-polymerizable monomer and the radical-polymerization initiator to the other. When said radical-polymerizable monomer is an unsaturated carboxylic anhydride, said unsaturated carboxylic anhydride as a starting material is preliminarily heated at 50.degree. to 250.degree. C., and then fed to the grafting reaction mentioned above. When the monomer is an unsaturated carboxylic acid or an acid anhydride of such an unsaturated carboxylic acid, an organic peroxide of a formula (I) is used as the radical-polymerization initiator. ##STR1## In this formula (I), two substituting groups connected directly to the benzene ring have an ortho-positional relationship or a meta-positional relationship, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6, which are the same as or different from one another, each denote a hydrogen atom or an alkyl group having the number of carbons of 1 to 10.

Abstract: An air inlet is provided at the bottom of a vehicle to open downwardly. The air inlet is connected by a first tube to an air cooler for a PDU and a down converter. A fan for inputting the flow of air and turning its direction 90 degrees is connected at the downstream of the air cooler. The fan is further connected by a second tube to an exhaust outlet. The air inlet is located above a fuel tank thus to prevent any object jumping up from the road surface from straightforwardly entering the air inlet while the vehicle is running. The exhaust outlet is located above a silencer and can thus be prevented from being frozen in the winter. Using the above arrangement, the present invention embodies an air intaking and exhausting apparatus in an air cooling system for air cooling the PDU and the down converter at higher efficiency without the help of the air cooler mounted in the interior of the vehicle.

Abstract: A power supply apparatus includes a controller. If the controller detects that the internal resistance of a battery detected by an internal resistance detecting unit is relatively high, then the controller switches a first switch from an open state to a closed state using a first threshold value with respect to the voltage difference between a battery voltage and a system voltage, and if the controller detects that the internal resistance of the battery is relatively low, then the controller switches the first switch from the open state to the closed state using a second threshold value which is smaller than the first threshold value.
