30 Sep 19
A wiring substrate for electronic component inspection apparatus includes a first laminate which is formed by stacking a plurality of ceramic layers and which has a front surface and a back surface, and a plurality of studs joined to the back surface of the first laminate, wherein each of the studs is composed of a flange portion which is circular in bottom view, and a bolt portion which perpendicularly extends from a center portion of an outside surface of the flange portion; and in a vertical cross section along an axial direction of the bolt portion, the outside surface from which the bolt portion protrudes has a curved surface which is convex toward an inside surface of the flange portion facing the back surface of the first laminate.

Particulate measurement apparatus and particulate measurement system
30 Sep 19
In a particulate measurement apparatus (300) of a particulate measurement system (10), a control section (600) provisionally determines in an anomaly determination process at S130 that a corona core wire (202) is in a wire-breakage anomaly state; namely, that the corona core wire (202) is broken, when a corona low-side current C1 is equal to or smaller than a current determination value C1min, and increments a wire-breakage anomaly counter CNB at S140.
