Title: Sound-absorptive structure
Inventor: IBUSUKI AKITSUGU
IPC: B01J35/02
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To not only reduce noise but also reduce pollutants like nitrogen oxides or sulfur oxides in the air discharged from the exhausted gas of cars. SOLUTION: A sound-absorption material 3 is charged in a hollow body 1 provided with an external layer 4 containing titanium dioxide at the surface and a number of openings 11 to irradiate ultraviolet rays on the titanium dioxide and activate it. In this way, noise of running cars is led into the hollow body 1 through the openings and absorbed by the sound-absorption material 3. The air near the ground level in which much pollutants like nitrogen oxides or sulfur oxides are contained, are stirred up by the wind pressure caused by running cars and led to the surface of the hollow body 1. The nitrogen oxides and sulfur oxides are guided to contact titanium dioxide of the external layer 4 and the nitrogen oxides and sulfur oxides are oxidized to nitric acid or sulfuric acid by the strong oxidizing force of the activated titanium dioxide and effectively removed.

Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To provide an electrolytic capacitor driving electrolyte which has a high conductivity and can be produced at a low cost by mixing an organic acid with a tertiary amine salt within a mixing solvent containing monoethylformamide and γ-butyrolactone and turning the tertiary amine salt of an organic acid created into electrolyte. SOLUTION: An organic acid and tertiary amine are mixed together in a mixed solvent containing monoethylformamide and γ-butyrolactone, and tertiary amine salt of an organic acid created by these acid-base neutralization reaction is used as electrolyte. By doing this, it is not necessary to remove by-products of the reaction and production can be realized at a low cost. Also, a mixed solvent of monoethylformaldehyde having a low viscosity and γbutyrolactone having a high dielectric constant is used, so that the γ-butyrolactone having a high dielectric constant in the mixed solvent increases the degree of dissociation of tertiary amine salt, and the monoethylformaldehyde can increase the mobility of dissociated ions so that a high conductivity can be obtained by the synergetic effect.

Title: Method and circuit for correcting contour
Inventor: SAKAMOTO KOICHI
IPC: H04N1/46
Filed: 1995-04-07
Abstract: PURPOSE: To prepare a required picture by generating a correction signal having amplitude set up adaptively to the amplitude of an edge signal. CONSTITUTION: An extraction circuit 10 extracts an edge signal based upon an inputted picture signal and outputs its amplitude value (k). The value (k) is suppled to a selection circuit 11 as an input address and a correction value (i) is generated from the circuit 11 while referring to an LUT and sent to a bit mask selecting circuit 12 and a comparator 13. The circuit 12 inputs the value (i) as an input address and outputs a bit mask M based upon the LUT. The comparator 13 compares the value (i) with a reference value O and outputs a high level signal when i>O or outputs a low level signal when i<O.  A signal compositing circuit 14 executes OR operation between the picture signal and the bit mask M in each corresponding bit when the compared output is the high level or executes AND operation between the picture signal and the bit mask M in each corresponding bit when the compared output is the low level. Consequently required contour correction can be executed in accordance with the amplitude of the edge signal.
