摘要： In an air conditioning apparatus, an air conditioning case has an upstream portion defining an air intake port through which air flows into the upstream portion substantially parallel to a core surface of a heat exchanger. The air intake port has a vertical dimension H1 that is smaller than a vertical dimension H2 of the core surface. The upstream portion has an air flow direction changing portion protruding inside of the upstream portion at a position opposite to the core surface above the air intake port. The air flow direction changing portion defines a clearance between the core surface and itself. A part of the air turned upward and further turned substantially parallel to the core surface strikes the air flow direction changing portion and flows toward the core surface through the clearance.

摘要： A high-frequency probe according to the present invention comprises a probe chip that has an end part that is pressed to an electrode and is covered by a electrically conductive outer enclosure, and slides in a vertical direction by an inner surface of this electrically conductive outer enclosure inside this electrically conductive outer enclosure. A signal conductive pattern is fixed inside this probe chip and is connected with a inner conductor having elasticity. The inner conductor can be bent in the vertical direction at a central part of a hole having an opening, which is sufficiently long in the vertical direction, in the center space of a ground conductor, which is fixed to an end part of the main block, when the inner conductor is pressed due to contact of the end part. In addition, the high-frequency probe has a thin shape of a maximum thickness in a transverse direction which is perpendicular to the vertical direction that is a direction of the probe being pressed to a device electrode. The maximum thickness is substantially equal to a pitch between device electrodes, and can be formed in the construction of unifying a plurality of high-frequency probes.
