Title: Method and device for evaluating propagation speed of surface slide wave substrate
Inventor: SAKIYAMA KAZUYUKI
IPC: H03H3/08
Filed: 1987-05-13
Abstract: PURPOSE:To evaluate the propagation speed of a substrate speedily and accurately by arranging the same surface slide wave substrate opposite, making a cut between an input and an output electrode in consideration of the depth and position, and optimizing the distance to the cut. CONSTITUTION:Normal comb-shaped input and output electrodes 1 and 2 of logarithm 6 are formed on, for example, an LiTaO3 36 deg. Y-cut substrate at an electrode-to-electrode distance of 60mm and the electrodes 1 and 2 are disconnected completely. Then the substrate 3 is installed on a substrate mounting jig 6 and a substrate 8 to be evaluated is sucked through a hole 5 for vacuum suction provided between both 3 and 6. Energy moves to the substrate is propagation, but remaining energy is stopped by the cut part 4 from being propagated to the output electrode 2. A surface wave which moves to the substrate 8, on the other hand, is propagated on the substrate 8 and converted into an electric signal after arriving at the electrode 2, and the signal is sent to a measuring instrument 9. Consequently, the propagation speed is calculated (<=35dB insertion loss) from the obtained delay time and the electrode distance between the input 1 and input 2.

When a given time has passed after the signal selecting circuit 111 was switched to the terminal (a) side, the signal selecting circuit 111 is switched to the terminal (b) side.  In synchronism therewith, a tracking circuit 120 starts tracking control at a tracking start signal 302 from a state variation detecting circuit 140, sequentially varies the revolving speed so that a water wheel operation state information signal J is minimized, and outputs an optimum revolving speed signal N1 to the signal selecting circuit 111.
