摘要： A surface acoustic wave device including, as formed on a piezoelectric substrate, one or a plurality of resonators connected together, each of the resonators comprising an interdigital transducer and a grating reflector, the object of the invention is to compact the device by improving the reflection efficiency of the grating reflector. When the grating reflector is a metal strip array reflector of the open type, the grating reflector has an electrode occupancy ratio of 0.7 to 0.8. Alternatively, when a metal strip array reflector of the short-circuit type is used, the grating reflector has an electrode occupancy ratio of 0.45 to 0.55, or when a metal strip array reflector of the interdigital type is used, the grating reflector has an electrode occupancy ratio of 0.7 to 0.85.

The one conductive plate has lower impedance than that of the conductive plate comprising the electric element and is connected between two anode electrodes. The other conductive plate has lower impedance than that of the conductive plate comprising the electric element and is connected between two cathode electrodes. As a result, the electric circuit device which has relatively low impedance and is capable of preventing the temperature rise is provided.

摘要： With a view to solving the problem of "pseudo-gap" in a parallel type MIG head and to improving its reproduction output, effective combinations of the principal magnetic path forming face and the gap-forming face were determined empirically for the case of using a single-crystal ferrite core material. The improved magnetic head comprises a pair of magnetic core halves made of a single-crystal ferrite, at least one of said magnetic core halves having a thin ferromagnetic metal film formed on the gap-forming face, and said thin ferromagnetic metal film abutting against the other magnetic core half with a non-magnetic material being interposed to form a magnetic gap, the improvement wherein the principal magnetic path forming face of the magnetic core half provided with said thin ferromagnetic metal film has a crystal plane generally designated {211} whereas a vector A that is parallel to the crystal axis in said principal magnetic path forming face and that is directed away from the gap-forming face forms an angle .theta. of the range 0.degree.-60.degree. or 150.degree.-180.degree. with a vector B that is parallel to the intersection of the principal magnetic path forming face and the gap-forming face and that approaches the face opposite to a recording medium.
