Title: Regeneration of exhaust gas purification catalyst
Inventor: ONISHI TOSHIYUKI
IPC: B01J38/02
Filed: 1990-10-26
Abstract: PURPOSE:To release adsorbed SOx and thereby recover denitration efficiency and organic substance-removing efficiency by thermally processing a catalyst contaminated by its adsorption of SOx and thermally processing the catalyst at specific temperature. CONSTITUTION:A catalyst for purification of exhaust gas containing an excess amount of air such as diesel engine exhaust gas has a molecular sieve structure contaminated by SOx and has ions exchanged by active metal. This catalyst is thermally processed at 450 to 800 deg.C, preferably 600 deg.C. Then the adsorbed SOx is released and discharged to an area outside a catalytic system in a state where the exhaust gas is circulated. After that, this catalyst is cooled to temperature near 400 deg.C, the denitration efficiency is recovered. Thus, the catalyst is regenerated and the denitration efficiency and organic substance-removing efficiency are recovered.

Title: Keyboard device for electronic musical instrument
Inventor: NIITSUMA SHINJI
IPC: G10H1/34
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a keyboard device for electronic musical instruments with which the nature specific to an acoustic piano may be faithfully reproduced and which may be produced at a low cost. SOLUTION: A wippen 30 has a long vibration radius and is designed to have the inertia moment larger than the inertia moment of a jack 44 and a hammer head 50 by installing a weight 41 thereto. When a keyboard 14 is depressed at a high speed, the keyboard 14 vibrates to depress the sliding tape 32 of the wippen 30 having the large inertia moment by means of an actuator 35. At this point, the sliding tape 32 is elastically deformed and the wippen 30 itself is slightly deformed as well, by which depressing force is accumulated therein and, therefore, the wippen 30 does not start the vibration immediately and begins to vibrate vigorously after a while.  The nature (the relationship between the key touch of the case the key is touched at a high speed and the magnitude of the electronic tone produced accordingly, etc.) specific to the acoustic piano is embodies by the wippen 30 and, therefore, playing information is determined by detecting the action of the wippen 30.

Abstract: PROBLEM TO BE SOLVED: To connect a waveguide element and an optical fiber array with higher coupling efficiency by making the spacings between V-grooves to be worked on a substrate member partially or wholly wider than the spacing between the waveguide cores of the waveguide type element to be connected to the optical fiber array. SOLUTION: The spacings between the V-grooves are made partially or wholly wider than the spacing between the waveguide cores 12 in such a manner that the distance L between the V-grooves 10 at both ends to be worked on the substrate of the V-grooves 10 satisfies equation 103×β<(L-L0)/L0<10-12×β when the distance between both ends core 12 of the waveguides is defined as L0 and the shrinkage rate on curing of an adhesive 11 used for mounting of the optical fiber array as β.  As the result, the distance between the cores 12 of the optical fibers which are parted mostly with each other among the optical fibers 6 constituting the optical fiber array may be more approached to the distance between the cores which are parted mostly with each other among the waveguide cores 12 of waveguide chips 5, therefor, the waveguide element and optical fiber array can be connected with higher coupling efficiency.

Filed: 1993-10-25
Abstract: PURPOSE:To attain highly accurate positioning by using a pilot radio wave whose spectrum is spread by a pseudo noise series in the interference radio wave sensor sensing and specifying a location of an interfering station sending a disturbing radio wave to a radio station implementing spread spectrum communication. CONSTITUTION:A pilot station 5 being a stationary station sends a pilot radio wave subject to spread spectrum processing by a pseudo noise series to position an interfering station 1. Each of monitor stations 6a-6d receives simultaneously the pilot radio wave and an interference radio wave sent from the interfering station 1, converts the signal form of the radio wave into a signal form suitable for transmission and sends the resulting signal to electric channels 3a-3d. A processing station 7 receives a signal sent from each monitor station via an electric channel and extracts time information included in the pilot radio wave through reverse spread processing and positions the interfering station 1 by taking the correlation of the interference radio wave between different monitor stations.
