Inventor: OSAKA MASAHIKO
IPC: H03L7/185
Filed: 1993-08-24
Abstract: A quadrature modulation circuit is comprised of two frequency generators which generate a first frequency signal and a second frequency signal, respectively, and a mixer which mixes the first frequency signal and the second frequency signal to generate the carrier wave whose frequency is different from both the first frequency and the second frequency.  By the quadrature modulation of this carrier wave according to a baseband signal, a transmission wave can be obtained.  Since the first frequency differs from the carrier frequency and the second frequency differs from both the carrier frequency and the first frequency, the output signals of the frequency generators are not affected by the transmission wave.

Title: Skate blade edge resurfacer
Inventor: ANDERSON BRADLEY J
IPC: B24D15/06
Filed: 1993-09-01
Abstract: ABSTRACT OF THE DISCLOSURE         A hand-held skate blade sharpening tool has a rotatble sharpening stone retained with a channel-shaped body member.          Removable pins mounted on the body are located adjacent the outer ends of the stone to limit longitudinal movement of the stone within a channel of the body member.  The body member has an access slot extending radially from the stone.  Elongated guides projecting upwardly adjacent the slot are transversly spaced at a distance substantially the same as the wieth of the skate blade to guide and limit lateral movement of the blade within the slot.          A transverse groove interrupting the slot and guides is open to the channel exposing the stone.  This enables the stone to be manually  rotated  within  the  channel  to  rotate  an  unused sharpening surface into alignment with the slot.
