    摘要: A device for detecting particulates includes: a filter; a filter container; an upstream pipe; a downstream pipe; an upstream detecting unit; and a downstream detecting unit. The upstream detecting unit has a branch flow route for receiving gas from the upstream pipe, a trapping portion, a transmitting portion for transmitting an electromagnetic wave to the trapping portion, and a receiving portion for receiving an electromagnetic wave from the trapping portion. The downstream detecting unit has a branch flow route for receiving gas from the downstream pipe, a trapping portion, a transmitting portion for transmitting an electromagnetic wave to the trapping portion, and a receiving portion for receiving an electromagnetic wave from the trapping portion. The amount of the particulates trapped in the filter is detected based on a difference between detection values of the mass of the particulates trapped in the upstream and downstream trapping portions.

    摘要: An optical waveguide device has an optical waveguide substrate and a supporting body for supporting the substrate. The substrate has a main body made of an electro-optic material and having a main face and an opposing face, optical waveguides, and electrodes for applying an electrical signal on the optical waveguides. At least a part of the opposing face of the supporting body opposing the substrate is covered with a conductive layer. It is thus possible to reduce the resonance due to substrate radiation leakage of the microwave signal into the whole of the optical waveguide substrate and supporting body.
