  • Publication number: 20230061042
    Abstract: In a method for manufacturing a micro vibration body having a three-dimensional curved surface, a mold defining a recess part is prepared, and a plate-shaped reflow material is arranged on the mold so as to cover the recess part. Pressure of a space defined by the recess part covered with the reflow material is reduced, and the reflow material is deformed by heating from an upper surface side opposite to a lower surface facing the recess part and by means of the pressure reduced. When the reflow material is deformed, a part of the mold is heated and / or cooled. As another example, when the reflow material is deformed, a mold having a different heat capacity portion is used to generate a temperature gradient in the mold.

  • Patent number: 9528930
    Abstract: An adhering matter determination portion includes an irradiation portion, a light receiving portion and a determination portion. The irradiation portion radiates a light to a plurality of different areas of a transparent plate. The light receiving portion converts reflected waves reflected at the different areas into electrical signals. The determination portion compares at least one of detection signals outputted from the light receiving portion with a determination threshold. When the detection signal is lower than the determination threshold, the determination portion determines that there is an adhering matter on the transparent plate. The determination portion compares the detection signals. When a difference of the detection signals is higher than a condensation determination value, the determination portion determines that the adhering matter is raindrops.
