Title: Demodulation circuit
Inventor: SHIRATORI AKIHIRO
IPC: H04B10/07
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To realize a demodulation circuit to receive infrared ray data with plural kinds of frequencies by the number of components of a minimum scale. SOLUTION: An edge detection circuit 2 detects an edge of an infrared ray input 1 and gives the detected edge signal to an LPF 3 whose number of taps is variable. Since an arithmetic execution signal 20 from the LPF 3 is proportional to a frequency of the infrared ray input 1, a frequency discrimination circuit 4 uses the arithmetic execution signal 20 to discriminate an input frequency and outputs a reception frequency 6. Furthermore, the circuit 4 sets the number of taps of the LPF 3 by a tap number setting signal 21 by utilizing that the arithmetic execution signal 20 is also proportional to the number of taps of the LPF 3.

Inventor: NISHI TAKASHI
IPC: G21F9/16
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To increase bending strength of charging vessel of radioactive waste constituted of concrete at least partly, improve impact resistivity and reduce leaching rate of radioactivity. SOLUTION: A solidifying vessel is lined in an iron drum 23 with a concrete vessel 24. The concrete vessel 24 is constituted of cement, fine aggregate, coarse aggregate and species adsorbing reinforcing matter. The cement is a hydraulic solidifyer of cement group and for the species adsorbing reinforcing matter, fiber active charcoal having adsorbing performance for radioactive unclear species is used. With the aide of the species adsorbing reinforcing matter in the concrete vessel 24, the bending strength of the concrete vessel 24 is increased and the impact resistivity is improved. As the nuclear species adsorbing reinforcing matter has a characteristic of adsorbing radioactive species, the solidifying vessel provided with the concrete vessel 24 can improve distribution coefficient for the radioactive species and so the leaching rate of radioactivity can be reduced.

Title: Underwater navigating body
Inventor: UCHINO MASANAO
IPC: B63G8/39
Filed: 1994-12-28
Abstract: PURPOSE: To provide an underwater navigating body which can reduce propagation of vibtation from the device interior to its wave receiver covering a wide frequency band and also withstand high depth pressure. CONSTITUTION: A minor axis part 15 of a specified length is fomed on the outer circumferential part of an underwater navigating body. A wave receiver 16 is formed in a cylindrical shape and its inside diameter is formed larger than that of the outer circumferential part of the minor axis 15. Magnets are respectively embedded in the minor axis part 15 and the part of the wave receiver 16 where it faces the minor axis part 15 and a gap 17 is formed by the resiliency of the magnets. The gap 17 is filled with water when the underwater navigating body is in the water. Because the mechanical impedance rate between the water and the metallic body is large, vibration propagation can be reduced by the gap 17 covering a wide frequency band. The wave receiver 16 is not easily deformed because its inner side and outer side are applied with equal water pressure.

Title: Image forming method and system
Inventor: SATO HITOSHI
IPC: H04N1/405
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of a color change in vector data independently of a color density and a line width of a vector. SOLUTION: A density value of each ink color is generated depending on color information of the vector data (S42), and the line width of the vector is discriminated (S51). When the line is not thin, the correction for color matching of each color is applied to the density of each ink (S52) and when the line is thin, correction for color matching is omitted (S53). The density of each ink is applied to a dither matrix prepared in advance to generate a mask matrix pattern (vector color pattern) to each ink (S46 and S55). In this case, when the line is thin and the density is low (S54), gamma conversion (S45) and shift processing (S57) are omitted. The vector data are converted into raster data by referencing the mask matrix pattern obtained in this way and the vector is printed on the basis of the raster data.
