Abstract: According to an embodiment, an inspection apparatus includes an irradiation mechanism, an imaging device, a movable mechanism, and a control processor. The irradiation mechanism irradiates an inspection target with light. The imaging device captures an image of the inspection target through a lens. The movable mechanism changes, with respect to an axis extending in an inspection direction for the inspection target, an angle between the lens and a horizontal plane or an angle between the imaging device and the horizontal plane such that a sample surface of the inspection target, a principal face of the lens, and an imaging face of the imaging device conform to the Scheimpflug principle. The control processor adjusts sensitivities in an image of the sample surface captured by the imaging device at different levels in the image depending on a position in a perpendicular direction to the inspection direction.

Abstract: An outdoor unit includes air blowers arranged in an upper part of a casing. First and second body recesses formed below first and second heat exchanger bodies of the casing and opening on sides of the casing are formed.

Abstract: A method for producing a polymer piezoelectric film, comprising: a process of moving and stretching a crystalline polar polymer sheet in contact with a conductive stretching roller having a diameter of at least 30 mm and a surface friction coefficient which has been reduced to such a level as to allow a relative displacement of the crystalline polar polymer sheet in contact with the conductive stretching roller: and a step in the process of applying a polarization voltage between an electrode disposed opposite to the crystalline polar polymer sheet and the conductive stretching roller to polarize the crystalline polar polymer sheet. As a result, it is possible to stably produce a polymer piezoelectric film exhibiting stable piezoelectricity over a large area. Especially, it is possible to obtain polymer piezoelectric film exhibiting a temperature-dispersion peak temperature of d31 piezoelectricity coefficient at least 120° C. and surface scratches extending in one direction.
