Title: Metal oxide semiconductor catalyst hydrocarbon sensor
Inventor: ADDIEGO WILLIAM PETER
IPC: G01N31/00
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To measure the concentration of hydrocarbon directly and accurately using a method for monitoring the performance of an exhauster by measuring the concentration of hydrocarbon in a mixed gas. SOLUTION: A mixed gas is brought into contact with a metal oxide semiconductor catalyst which can start at least one catalytic reaction and/or chemical adsorption of selected hydrocarbons. Variation in the conductivity of a metal oxide is measured and converted into the total concentration of non-methane based hydrocarbon in the mixed gas. Such a catalytic reaction is selected from a group of partial oxidation, oxidation dehydrogenation, oxidation coupling and isomerization and the hydrocarbons are selected from a group of alkane, alkene and aromatic hydrocarbon.

Title: Electroluminescence
Inventor: IWAMURA MITSUO
IPC: H05B33/22
Filed: 1998-12-17
Abstract: PROBLEM TO BE SOLVED: To provide EL(electroluminescence) with less uneven brightness, high brightness, rarely generating a short mode at a low price. SOLUTION: A light-emitting material layer 4 and a dielectric layer 5 are interposed between a transparent electrode 3 and a back electrode 6, and light is emitted from the light-emitting material layer 4 by applying voltage across both electrodes. A relatively thin mixture layer 11 formed by dispersing a light- emitting material and a dielectric in a binder is placed between the light- emitting layer 4 and the dielectric layer 5 in order to enhance flatness and obtain interface smoothness. The viscosity of mixture ink for the mixture layer 11 is lower than the viscosity of light-emitting material ink obtained by dispersing a light-emitting material for the light-emitting material layer 3 in a binder. The surface of the mixture layer 11 is made flat, the thickness is made uniform, generation of uneven brightness and generation of a short mode are prevented.  The dielectric layer 5 formed on the mixture layer 11 is made uniform since particles of the dielectric are fine, uniform dielectric constant can be obtained and generation of uneven brightness is prevented.

Title: Sound field control processing circuit
Inventor: TAKAHASHI TORU
IPC: H04B14/04
Filed: 1992-12-25
Abstract: PURPOSE:To perform highly precise sound field control through a small number of filters by compressing a sound field coefficient based upon a sound field impulse response adaptively to PASC and decreasing the number of parameter setting points, and performing a convolutional process for a PASC signal by a variable bit accumulator. CONSTITUTION:The PASC signal reproduced by a reproducing head from a digital audio cassette tape is applied to the variable bit accumulator 1 after 10-8 demodulation. A sound field control coefficient storage part 3, on the other hand, is stored with sound field control coefficients of parameters compressed corresponding to PASC. For the compressed sound field control coefficients, the PASC signal is convolutionally processed by the variable bit accumulator 1 under the control of a control part 4, but the timing is controlled by the control part 4. The PASC signal to which a sound field signal is added is decoded by a decoder 2 into a digital audio signal, which is reproduced by DAC, thereby obtaining a reproduced sound having desired sound field effect.
