Abstract: In a radiator (1) for use in radiating heat generated by an electronic component (5), a high-frequency current suppressor (2) is attached to that principal surface of the radiator which faces the electronic component. The high-frequency current suppressor serves to attenuate a high-frequency current flowing through the radiator and having a frequency within a frequency band between several tens MHz and several GHz. It is preferable that a heat-conductive sheet is formed on the high-frequency current suppressor. An insulating sheet may be formed on the high-frequency current suppressor.

Abstract: The present invention includes a braiding machine having three or more vessels, each vessel having an outer housing and an internal telescoping mandrel, the vessels being removably mounted on a portion of two wheel drums, the drums rotating and the direction of each vessel around the drum being altered by a toggling detent. To use the device, hair is wrapped onto an extended telescoped mandrel, the mandrel is collapsed, and a housing is placed on the mandrel to provide a vessel; three or more vessels are then mounted onto the drums and, when the device is powered, the hair on the mandrels emerges from the device as a braid.
