Title: Longitudinal double mode saw filter
Inventor: TAKAGI MICHIAKI
IPC: H03H9/25
Filed: 2001-03-09
Abstract: PROBLEM TO BE SOLVED: To provide a longitudinal double mode SAW filter having flat pass- band characteristics. SOLUTION: In the longitudinal double mode filter, an energy-confined SAW resonator is fabricated on a frequency increasing piezoelectric substrate and then an IDT is divided into three, i.e., a first IDT1 on the transmission side, a second IDT2 on the receiving side and a third IDT3 between them, so that the amplitude of oscillatory displacement in two modes S0 and A0 for synthesizing the filter can be controlled. When the frequency potential is rendered appropriate by varying the electrode period length of the IDT1, IDT2 and IDT3, resonance amplitude is equalized between the S0 mode; and since the A0 mode and the transmission characteristics of pass band can be flattened, a relatively wide band width of 1,000-1,500 ppm can be realized, using a substrate having a small electromechanical coupling coefficient, e.g. a quartz substrate.

Abstract: PROBLEM TO BE SOLVED: To provide a digester which is capable of surely digesting organic matters containing a hardly biodegradable material and has high treatment capability. SOLUTION: Filtering means 5 for compartmentalizing the sludge-containing liquid in a chamber 1 is installed between a material-to-be-treated introducing port 3 and a digested sludge discharge port 2 and the organic matter, such as the hardly biodegradable material, which is larger than a prescribed size and takes time to be digested is held in the sludge-containing liquid on the material-to-be-treated introducing port 3 side and is sufficiently digested and is prevented from moving to the digested sludge discharge port 2 side until its size is made smaller than the prescribed size. As a result, the organic matters, such as the hardly biodegradable material, larger than the prescribed size is prevented from being discharged together with the digested sludge while the organic matter is kept undigested in discharging the digested sludge from the digested sludge discharge port 2.  The hardly biodegradable material increases its surface area and exhibits a function as a carrier of digesting bacterial as the digestion progresses and therefore the contact efficiency of the organic matters and the digesting bacteria in the sludge-containing liquid is improved and the digestion rate of the organic matter is improved.
