摘要:
A cooling device includes: a cooling fan; a shroud provided at an outer circumferential side of the cooling fan; and a ring having an inner circumferential wall and an outer circumferential wall. The inner circumferential wall is provided on the shroud and adjacent to an outer circumference of the cooling fan. The outer circumferential wall surrounds the inner circumferential wall, and an air-flow-direction downstream side end of the outer circumferential wall is positioned at a further downstream position in an air flow direction than an air-flow-direction downstream side end of the inner circumferential wall. An air-flow-direction downstream side end of an outer circumferential edge of the cooling fan is positioned at a further downstream position in the air flow direction than the air-flow-direction downstream side end of the inner circumferential wall.

A cooling device includes: a cooling fan; a shroud provided at an outer circumferential side of the cooling fan; an inner circumferential wall provided on the shroud and adjacent to the outer circumference of the cooling fan so as to surround the cooling fan; an outer circumferential wall provided to surround the inner circumferential wall. An air-flow-direction downstream side end of the outer circumferential wall is positioned at a further downstream position in an air flow direction than an air-flow-direction downstream side end of the inner circumferential wall. The cooling fan is rotatable within a space provided on a radially inner side of the inner circumferential wall. The air-flow-direction downstream side end of the outer circumferential wall is provided at a further upstream position in the air flow direction than an air-flow-direction downstream side end of the cooling fan.

An image processing apparatus includes a first detecting unit configured to detect an object in an image; a determining unit configured to determine a moving direction of the object detected by the first detecting unit; and a second detecting unit configured to perform detection processing of detecting whether the object detected by the first detecting unit is a specific object on the basis of the moving direction of the object determined by the first determining unit.
摘要:
A stationary guide for an engine timing chain is mounted by engagement of two longitudinally space mounting holes with two pins protruding from an engine block. At least one of the holes is formed with a stop wall positioned to prevent improper reverse mounting of the guide, and preferably positioned so that its abutment with the end of a mounting pin positions the guide in proper alignment with the normal path of travel of the timing chain.
