An antenna includes a cylindrically shaped dielectric resonator placed on a longitudinally extended axis of an elongated dielectric strip disposed on a planar conductor and another planar conductor having an opening covers the dielectric strip with the opening on the dielectric resonator. There may be another dielectric strip placed perpendicularly to the first dielectric strip such that the dielectric resonator is where the lines longitudinally extended from the axes of both dielectric strips will cross.

A dielectric antenna is provided which is capable of setting the radiation of electromagnetic waves at a desired angle. The dielectric antenna has a nonradiative dielectric guide (an NRD guide) of a construction in which a dielectric strip is sandwiched between a first planar conductor and a second planar conductor. A dielectric resonator is disposed between the first planar conductor and the second planar conductor along the extension line of the dielectric strip, and a plurality of slots are disposed in the second planar conductor above the dielectric resonator and symmetrically with respect to the dielectric resonator.

A surface acoustic wave device comprises an input and output transducers. A signal is supplied from a signal input circuit to the input transducer and a surface wave corresponding to the input signal is propagated from the input transducer to the output transducer, from which an electrical signal corresponding to the surface wave is withdrawn and is applied to a signal output circuit. An impedance converting circuit is inserted in series between the signal input circuit and the input transducer and/or between the output transducer and the signal output circuit. It has been discovered that this arrangement reduces the electrical triple transit echo.

Apparatus manufactures thin confectionery products with uniform shapes and has first and second drying apparatuses between shape cutting and baking apparatuses for adjusting water content of raw dough pieces. The first drying apparatus has upper and lower levels, the upper level having conveyor belts at plural stages for transporting the dough pieces under hot air atmosphere and the lower level having conveyor belt for cooling, and conveyor belt for maturing the cooled pieces. The second drying apparatus has atmosphere at lower temperature than the first drying apparatus and plural rotary drums each having an inlet and an outlet and being rotatably mounted in the second apparatus. A chute transports the raw dough pieces from uppermost to lowermost ones of the rotary drums.

An RF converter includes a video modulator and a sound modulator. A modulated video signal from the video modulator and a modulated sound signal from the video modulator are mixed and conducted to a surface acoustic wave (SAW) filter constituted as a band pass filter, an RF television signal being the output of this surface acoustic wave filter. A high frequency side of the amplitude characteristic in the pass band of the surface acoustic wave filter is enhanced in comparison with a low frequency side thereof.

Provided is a belt-driving roller that can be manufactured at low cost for driving a wire mesh belt used as a conveyor belt in a circulating manner, and also provided is a food manufacturing apparatus using the driving roller. A belt-driving roller comprises: a rotation shaft; and toothed rollers concentrically attached to the outer circumference of the rotation shaft. The toothed roller comprises: a cylindrical base part on the outer circumference of which teeth are provided in a plurality of rows to engage with a wire mesh belt; and an attachment means for attaching the base part to the rotation shaft. The belt-driving roller is used in a food manufacturing apparatus.

A piezoelectric thin-film resonator includes a supporting substrate. A piezoelectric thin-film is formed on the supporting substrate. A lower electrode and an upper electrode are formed with the piezoelectric thin-film therebetween. The stiffness of at least one of the lower and upper electrodes is higher than that of the piezoelectric thin-film.
