摘要:
A drive motor is supported and fixed onto a motor support plate composing a support member through vibration proof rubber which damps vibration, the frequency of which is not less than 1 kHz. Due to the foregoing, it becomes difficult for the vibration generated from the drive motor itself, to be transmitted to the support member so that the generation of resonance noise can be prevented.

A drive motor 42 is supported and fixed onto a motor support plate 44 composing a support member through vibration proof rubber 45 which damps vibration, the frequency of which is not less than 1 kHz, to be not more than 50%. Due to the foregoing, it becomes difficult for the vibration generated from the drive motor 42 itself, the frequency of which is not less than 1 kHz, to be transmitted to the support member so that the generation of resonance noise can be prevented. Further, a protrusion 44a is provided on a surface of the motor support plate 44 and the resonance frequency of the support member is adjusted to be not less than 1 kHz. Due to the foregoing, even when the vibration of the drive motor 42, the frequency of which is lower than 1 kHz, is transmitted to the support member, resonance noise is not generated.

A battery cooling apparatus for positively cooling an in-vehicle battery is disclosed. Air that has passed through a cooler (5) is supplied to batteries (1), and only internal air, but not external air, passes through the cooler (5). In this way, the batteries (1) can be cooled without being greatly affected by the disturbances such as the heat of an exhaust pipe and sunlight. Thus, the batteries (1) can be sufficiently cooled without increasing the heat radiation area, i.e. the surface area of the batteries (1). Noise of cooling air flow can be reduced while at the same time suppressing increases in both size and production cost of the battery.

In a cooling system for cooling a heating element mounted in a vehicle, a radiator is located at a position higher than a heat sink, which absorbs heat from the heating element. When the amount of heat generated from the heating element, which is detected by a sensor, is greater than a predetermined first value, a blower is operated. Further, when the detected amount of heat is greater than a predetermined second value that is higher than the predetermined first value, a pump is operated. When the detected amount of heat is equal to or less than the predetermined first value, the pump is stopped and the cooling water is circulated by a principle of heat siphon. Accordingly, power consumption of the pump is reduced. Further, power consumption of the cooling system is reduced or an increase in power consumption of the cooling system is restricted.
摘要:
The maximum radiating value of a radiator (5) is not more than the maximum heat value of an IGBT (3). Even if the radiating capacity of the radiator (5) is not more than the maximum heat value of the IGBT (3), the temperature of cooling water returned to the heat absorber (4) can be maintained low and the size of the radiator (5) can be decreased because the increasing rate of the temperature of the cooling water returned to the heat absorber (4) is sufficiently smaller than that of the heating element (3), due to the heat capacity of the fluid, the heat absorber (4) and the radiator (5).

Facial feature point reliability generating means generates a reliability map of each facial feature point from a facial image. Initial facial feature point position calculating means calculates the position of each facial feature point in the facial image based on the reliability map. Off-position facial feature point judgment means judges whether or not each facial feature point is an off-position facial feature point not satisfying a prescribed condition. Facial feature point difference calculating means calculates the difference between the position of each facial feature point, excluding those judged as the off-position facial feature points, and the position of a corresponding point of the facial feature point. Facial feature point position correcting means corrects the determined positions of the facial feature points based on the results of the judgment by the off-position facial feature point judgment means and the calculation by the facial feature point difference calculating means.
