Title: Surface acoustic wave element
Inventor: MOCHIZUKI NORIHIRO
IPC: H03H9/70
Filed: 1990-09-14
Abstract: PURPOSE:To eliminate interference and to improve the characteristic of the element by providing a conductive thin film between a surface acoustic wave waveguide and an acoustoelectric transducer so as to suppress it that a convolution electric signal generated in the surface acoustic wave waveguide reaches the acoustoelectric transducer as an electromagnetic wave. CONSTITUTION:When 1st and 2nd surface acoustic waves propagate in opposite direction to surface acoustic wave waveguides 4-1-4-n, a convolution electric signal resulting from two input signals whose center angular frequency is 2omega is generated in the surface acoustic wave waveguides 4-1-4-n by parametric mixing phenomenon and radiates an electromagnetic wave. However, the electromagnetic wave is shielded by a conductive thin film 7 arranged between the surface acoustic wave waveguides 4-1-4-n and the acoustoelectric transducer 5 before the wave reaches the acoustoelectric transducer 5 and the arrival to the acoustoelectric transducer 5 is suppressed. Thus, the interference by the electromagnetic wave is suppressed in the acoustoelectric transducer 5 and the characteristic of the element is improved.

Inventor: SASAKI SADAO
IPC: B23K26/00
Filed: 1992-09-14
Abstract: PURPOSE:To eliminate the need for special pre- and post-treatments at the time of executing laser beam processing by using a laser beam which is hardly absorbed. CONSTITUTION:A computer causes an aq. copper sulfate soln. to be discharged to a point P so that the soln. is applied like a spot on this point upon recognition of the positioning of a soln. discharge point 5a at the point P which is the processing start point of a substrate 1. The computer, then, moves an X-Y-Z stage to align an optical axis 18 and the point P and instructs, at the point of this time, a laser oscillator to output the laser beam. The laser beam 23 cast to the point P is absorbed in the aq. copper sulfate soln. to raise the soln. to a high temp. and the substrate 1 in the lower part thereof is made into a molten state. The subsequent laser beam processing is well executed even if the aq. copper sulfate soln. is not applied. Namely, the cutting processing from the point P to the point Q is well executed without the application of the aq. copper sulfate soln. A cutting groove 1a is consequently formed on the substrate 1.
