A drill for chip removing machining, including a drill body, and a replaceable cutting insert mounted in a pocket formed in a front tip of the drill body. A chip flute extends backwardly from the pocket along the drill body, and the cutting insert is fixed in the pocket by a screw including a head and a shank having a male thread. The cutting insert includes a through hole extending between a topside and an underside. The hole has a basic shape that is rotationally symmetrical in relation to a center axis, and is delimited by a series of surfaces including a mouth surface, converging downward from the topside, and a shoulder surface. The head of the screw is kept pressed against the shoulder surface when the male thread of the screw is tightened in a female thread included in a hole that mouths in a bottom of the pocket. The mouth surface in the hole of the cutting insert has a trumpet-like, cross section-wise convex shape adjacent to the topside of the cutting insert.

The invention provides a TEM loudspeaker-based movable electromagnetic pulse radiation wave simulator, and aims at meeting the requirements of strong low-frequency radiation capability and small size.The TEM loudspeaker is an exponential gradual loudspeaker, namely, the heights of upper and lower plates are changed exponentially; a metal straight plate having a same width with the mouth surface of the exponential TEM loudspeaker is loaded at the end of the mouth surface; an inclined metal plate is added; and. the beginning end of the inclined metal plate is electrically connected via a resistor. In such way, diversion is carried out for twice by using the metal plates, so that the problem that the conventional TEM loudspeakers have relatively strong reflection at the ends is avoided and the enhancement of low-frequency radiation capability is realized; the resistor at the beginning end of the inclined plate not only absorbs the current on the inclined plate, but also avoids the reflection interference of a forward radiation field of the simulator; and the inclined plate is inclined from the mouth surface toward the vicinity of a feeding end, thereby achieving the effect of reducing the size of the simulator.

The invention relates to a dual-polarization feed source fed by a broadband ridged orthogonal mode converter. The dual-polarization feed source comprises a ridged horn antenna and an orthogonal mode converter integrated with the antenna, wherein the orthogonal mode converter is matched and connected with four side ridges (1) of the horn antenna, and a matching frustum (2) in the middle of the orthogonal mode converter extends to form a central ridge (3) of the horn antenna.

A hand-held, ergonomic instrument with an LED that emits actinic light in visible wavelengths mounts a replaceable applicator cup with a reservoir for a tooth whitening composition held in place against a user's tooth during a whitening procedure. Actinic light is directed onto the tooth surface through a window in the cup and the tooth whitening composition substantially without attenuation, delivering at least about 100 milliwatts per square centimeter of light energy to the tooth surface. The cup includes a rigid body for mounting the cup to the instrument and an opaque flexible sleeve molded in place over the outside of the body to form a seal with the tooth surface and prevent exposure of soft mouth surfaces to the actinic radiation during a whitening procedure.
