摘要： An in-vehicle radar apparatus includes a transmission and reception means which transmits a radar wave ahead of an own vehicle and receives a reflected wave corresponding to the radar wave from a target; a reception strength detection means which repeatedly detects reception strength of the reflected wave; a distance detection means which repeatedly detects a distance from the own vehicle to the target; an approximate expression calculation means which calculates an approximation expression expressing the reception strength using the distance as a variable from the reception strength repeatedly detected by the reception strength detection means and the distance repeatedly detected by the distance detection means; and a determination means which determines a height of the target from a road surface based on values of coefficients of the approximation expression.

摘要： A double pipe forms an inner flow path, through which a low-pressure side refrigerant flows, inside an inner pipe, and forms an inner-outer flow path, through which a high-pressure side refrigerant flows, between the outer pipe and the inner pipe. It comprises an expansion valve side connector and a counter-expansion valve side connector which are interposed between distal ends of the outer pipe and the inner pipe and members to be connected. An outer diameter of the outer pipe is 30 millimeters or less. A ratio of a difference between an inner diameter of the outer pipe and an outer diameter of the inner pipe with respect to the inner diameter of the outer pipe is 25% or less. A sealing member is provided to prevent a refrigerant leakage. The plurality of members are mechanically fixed.
