摘要:
Feature information collecting apparatuses, methods, and programs acquire vehicle position information that represents the current position of a vehicle, acquire image information for a vicinity of the vehicle, and carry out image recognition processing on recognition target objects that are included in the image information. The apparatuses, methods, and programs store recognition information in a memory that represents a result of the image recognition of the recognition target objects in association with information for the recognition position of the recognition target objects, the recognition position determined based on the vehicle position information. The apparatuses, methods, and programs extract, as learned features, recognition target objects that can be repeatedly recognized by image recognition based on a plurality of sets of recognition information related to the same position, the plurality of sets of recognition information being stored due to the image information for the same position being recognized a plurality of times by image recognition.

A hydraulic power transmission joint provided with a rotary valve in which a first enclosing hole is bored and moreover, a first spool valve, a first spring, a first pin member and a first communicating hole are provided. Further, a second communicating hole is also provided therein in such a manner as to be coaxial with the first communication hole. Moreover, a second enclosing hole having a smaller diameter is bored therein. Furthermore, a second spool valve having a diameter smaller than that of the first spool valve, a second spring, a second pin member, a third communicating hole, a fourth communicating hole and an orifice are provided therein. Further, a valve element, whose position is controlled, is enclosed in a high-pressure chamber formed in the rotary valve. Additionally, a gap between a pin portion of the pin member for holding the valve element and a communicating hole, which provides communication from the high-pressure chamber to the enclosing hole for enclosing the pin member, is used as the orifice for generating fluid resistance.
摘要:
In an ultraviolet exposure apparatus, substances contained in an atmosphere contacting a lens surface are reduced, the substances generating accumulations on the lens surface. Openings are formed in the wall of a lens barrel to allow the atmosphere to be replaced by a proper gas. The proper atmospheric gas may be a gas not containing oxygen such as a nitrogen gas, or clean air obtained by intentionally generating accumulations by applying ultraviolet light to source air. A ultraviolet light source is preferably cooled by a cooling system different from the cooling system of a lens optical system.
