Abstract: A structural body is provided in fluid, perpendicular to a typical flow direction of the fluid. The structural body includes a cylindrical insulating body having at least one hollow portion and at least one conducting body positioned in the hollow portion of the insulating body. In a cross section of the insulating body having a normal line in an axial direction of the insulating body, the following relationship is satisfied: 1.5×Diy≦Dix≦15×Diy where Dix is a length of the insulating body in the typical flow direction (direction x) and Diy is a maximum value of a length of the insulating body in a direction (direction y) perpendicular to the typical flow direction.

Abstract: A method for producing a ceramic molded body, the method including: a molding step of subjecting a ceramic molding material to extrusion molding using an extrusion molding machine equipped with a temperature control portion to provide a ceramic molded body; a cutting step of cutting the ceramic molded body to have a predetermined length; and a dimension measuring step of measure a dimension of the cut ceramic molded body. A relationship between a temperature of the temperature control portion and the dimension of the cut ceramic molded body is previously obtained, and based on the relationship, an appropriate temperature of the temperature control portion is calculated from the dimension of the ceramic molded body measured in the dimension measuring step, and the temperature control portion is controlled to the appropriate temperature in the molding step.

Abstract: An ozone generator includes a housing having an internal cavity and a plurality of electrode pairs located in the internal cavity. The electrode pairs each contain two electrodes arranged at a distance of a predetermined gap length, and a discharge space is formed between the two electrodes, whereby ozone is produced when a source gas flows at least between the two electrodes and a discharge is generated between the two electrodes. The ozone generator has a non-discharge portion in an arbitrary cross-section having a normal direction parallel to a main flow direction of the source gas in the internal cavity.
