Title: Surface acoustic wave resonance filter
Inventor: TABUCHI TOYOJI
IPC: H03H9/64
Filed: 1983-07-27
Abstract: PURPOSE:To obtain a filter with excellent in-band characteristics, by setting an electric length between two transducers and an electric length between the transducer and an equivalent reflecting plane of a reflector to a prescribed value so as to eliminate the effect of a reflected wave. CONSTITUTION:A part of a direct wave reaching directly the transducer 6 among excited waves is a reflected wave 9, which is returned to the transducer 5. On the other hand, the wave reaching the adjacent reflector 1 is reflected on the equivalent reflecting plane 11 and passes through the transducer 5, and a part of it becomes a reflected wave 10. The reflected wave 10 is reflected againt on the equivalent reflecting plane 11 of the reflector 1 and returns to the transducer 5. The two reflectors 9, 10 are interferred with each other on the transducer 5, which causes a ripple in the in-band characteristic of the filter. In order to avoid the effect of the reflected wave, the electric length l3 between the transducers 5, 6 is brought different from by an odd number multiple from the length of twice the electric length l4 between the transducer 5 and the equivalent reflected plane 11 of the transducer 5. Thus, the filter having excellent in- band characteristic is obtained.

IPC: G03B27/72
Filed: 1988-06-01
Abstract: PURPOSE:To obtain a bright image from an original where high density areas and low density areas are mixed by carrying out a preliminary scanning to detect the density of the original and choosing whether to carry out the exposure control by a fixed exposure method or to carry out the exposure control by a sequential exposure method. CONSTITUTION:Reflected beam from the original makes incidence on a beam sensor 53 during the preliminary scanning. The outputting signal from the light sensor 53 is given to an amplifier 203. The outputting voltage of the amplifier 203 is sampled by CPU 201 and is stored in RAM 206 as the detected data. Whether the original is one where high density areas and low density areas are mixed is detected by CPU 201, based on the detected data, a choice is made whether to carry out exposure scanning by the sequential exposure control means, or to carry out exposure scanning by the fixed exposure control means, and an exposure lamp driving circuit 205 is controlled at the time of scanning. Thus a bright image can be obtained, even from the original where high density areas and low density areas are mixed.

Filed: 1991-06-07
Abstract: PURPOSE:To obtain a mass detection device which detects a mass within a mixed-phase container where the mixed phase is formed by a gas and a particle and is subjected to fluidization safely and accurately. CONSTITUTION:An electrostatic capacity detection means 50 constitutes a means for detecting a mass 20 which is generated on an inner-wall surface of a fluidized bed olefin polymerization reaction container 1 together with a converter 17 and a recording alarm portion 19.

Title: Rice bran fuel and its production
Inventor: HASEGAWA HIDEO
IPC: C10L5/44
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To produce a rice bran fuel, producible at a low cost without requiring excessively large-sized equipment, good in ignitability in use and capable of readily controlling the heating power and provide a method for producing the rice bran fuel. SOLUTION: This rice bran fuel F is composed by mixing 40-70wt.% rice bran with 15-40wt.% vegetable oil and 10-25wt.% combustible plastic material, uniformly kneading the components and filling the resultant kneaded combustible material 1 in a combustible packaging material 3. Since the vegetable oil is gasified on the surface and the rice bran becomes a combustible wick, the ignitability is excellent without extending the heating power to the wick part. The fuel burns with lasting quality due to the combustion by the gasification of the vegetable oil on the surface and the fire lasts sufficiently long. The combustible plastic material regulates the heating power and the combustion lasts with a heating power so as to burn a wood. Since the rice bran fuel F is slowly and completely burned from the surface, no cinder remains, resulting in the convenience for after adjustment. Since the solid state is retained, the rice bran fuel F has excellent effects on convenient usability as a fuel in a stove or the fields. Since the production thereof is readily carried out without requiring excessively large-sized equipment and wastes can be used, the rice bran fuel F can be provided at a low cost.
