Abstract: A particle diameter distribution of shot media before forming an operating mix is bimodal and substantially continuous, and out of a first particle group corresponding to a first peak and a second particle group corresponding to a second peak, one is an aggregate of particles in a shape having an angular part while the other is an aggregate of particles in a shape configured with a convex curved surface.

Abstract: A blasting processing method using shot media. A particle diameter distribution of the shot media before forming an operating mix is bimodal and substantially continuous, and both a first particle group corresponding to a first peak and a second particle group corresponding to a second peak are aggregates of particles in a shape having an angular part.

Abstract: The invention provides a connector-attached dielectric waveguide that allows the dielectric waveguide to be easily connectable with an opposite component and is capable of forming a connection structure exhibiting low transmission and return losses of a high frequency signal. The connector-attached dielectric waveguide includes a dielectric waveguide and a connector. The dielectric waveguide includes a dielectric waveguide body and a dielectric waveguide end. The dielectric waveguide end has a smaller cross-sectional area than the dielectric waveguide body.

Abstract: The present disclosure relates to a shot used for blast processing, the shot being made of an iron-based alloy containing C: 0.20 to 0.50% by mass, Si: 0.50 to 1.10% by mass, and Mn: 0.50 to 1.15% by mass as additive elements, in which a mass ratio of C to Si is 0.30 to 0.75, a mass ratio of C to Mn is 0.30 to 0.75, and a mass ratio of Si to Mn is 0.70 to 1.60, and a Vickers hardness of the shot is HV 400 to 800.

Abstract: The invention provides a dielectric waveguide for transmitting millimeter waves or sub-millimeter waves. The dielectric waveguide is easily processed and connected even when having a small diameter, and can provide a connection structure exhibiting low transmission and return losses of high frequency signals. The dielectric waveguide includes a dielectric waveguide body and a dielectric waveguide end having a lower permittivity than the dielectric waveguide body. The dielectric waveguide body and the dielectric waveguide end are seamlessly and monolithically formed from the same material.
