  • Patent number: 11619604
    Abstract: A bubble detection method includes flowing a fluid through a conduit containing at least one bipolar electrode, applying an electric field across the fluid in the conduit, and detecting a presence of a bubble in the fluid when the bubble flows around or through the bipolar electrode by detecting a current or voltage output from the at least one bipolar electrode.
    Type: Grant

  • Patent number: 7943054
    Abstract: Cracks are generated in a resist film part used to form an opening part in a photoreceptor part, whereby etching is performed as far as the inter-layer insulating film in unintended portions. In order to prevent this, the resist pattern used as an etching mask is formed in a shape that disperses the stress. The stress is generated because the resist is hardened by post baking after having been exposed and developed. In order to disperse the stress, the opening part of the resist pattern is formed in a planar shape that has no corners.
