Title: Elastic surface wave device
Inventor: SATOU KOUJI
IPC: H03H9/02
Filed: 1983-03-25
Abstract: PURPOSE:To suppress unnecessary an acoustic reflected wave generated in a group by spacing a gap of half of a wavelength between electrode fingers in a nonintersection area which does not contribute directly to the excitation of grouped surface waves. CONSTITUTION:An elastic surface wave device has an input transducer 32, output transducer 33, and shield electrode 34 on a piezoelectric base body 31; and the gap 37 which is half of a wavelength is left between the 1st group G1 and the 2nd group G2 of a comb-shaped electrode in the nonintersection area and electrode fingers 38 having 1/2 wavelength width are provided adjacently to the 2nd group G2. Unnecessary acoustic reflected waves generated both end parts of electrode fingers 39-a and 39-b in the group G1 are suppressed because they are out of phase with unnecessary acoustic reflected waves generated both end surfaces of electrode fingers 39-c and 39-d in the group G2 arranged at a distance of 1+1/4 wavelength, so that no unnecessary acoustic reflected wave appears in the groups G1 and G2 on the whole.

Title: Method for reading shape of elastically deformable article
Inventor: ARAN SHIYANSABOAARU
IPC: B24B17/02
Filed: 1992-03-06
Abstract: PURPOSE: To avoid the pre-deformation of a spectacle rim metal etc., by mathematically drawing the coordinate values at which the pressing force of a contact feeler becomes zero from two systematically read continuous coordinate values at which the pressing force of the feeler does not become zero. CONSTITUTION: The head 14 of a contact feeler 12 is pressed against the rear side of the rim metal or rim frill 10 of a spectacle frame 11 to be read for contour with a specific force F and the coordinate values of the feeler 12 are recorded whenever the feeler 12 is pressed. The local deformation of the rim metal or rim frill 10 inevitably occurs when the feeler 12 is pressed against the rim metal or rim frill 10 with the force F. It is presumed that the local deformation stays within the elastic limit of the rim metal or rim frill 10. By systematically reading two continuous coordinate values, a first set value F1 at which the pressing force F does not become zero and a second set value F2 at which the force F does not become zero and which is different from the first value F1 are obtained. The coordinates of the set value F0 at which the force F of the feeler 12 becomes zero is mathematically drawn from the two read coordinate values.
