Abstract:
A jack on a whippen incorporated in an upright piano drives a hammer assembly to rotate toward musical strings for producing sound, and a soft pedal causes the hammer assembly to become closer to the musical strings, wherein the upright piano comprises an adjusting mechanism operative to move the whippen upon manipulation of the soft pedal for eliminating gap between the jack and the butt as well as modifying rotating distance of the whippen, and a driving link assembly coupled between an associated key and a damper mechanism so that the whippen moved by the adjusting mechanism has no influence of action of the damper mechanism, thereby keeping key-touch ordinary under the manipulation of the soft pedal.
Abstract:
An electrophotographic toner composition comprising a toner particle and an additive is disclosed, the toner particle comprising at least a binder resin and a colorant, and the additive being an amorphous titania fine particle subjected to a surface treatment using a coupling agent.
Abstract:
A semiconductor memory device wherein at least one of a storage node contact hole and a bit line contact hole includes a first contact hole made in a first inter-layer insulating film formed over a gate electrode and a second contact hole made in a second inter-layer insulating film formed over an electrically conductive material embedded up to a level higher than the gate electrode in the first contact hole which is contacted with the electrically conductive material, the conductive material being exposed by etching a part of the second inter-layer insulating film, whereby the size of the memory device can be made small and the reliability can be improved. Further, a capacitor is formed in a layer higher than a bit line thereby to facilitate the processing of a storage node electrode to increase the capacitor area and to improve the reliability since it is unnecessary to carry out patterning a plate electrode within a cell array. With the above construction, a short-circuiting between the embedded layers is removed and a good quality of the second inter-layer insulating film is formed.
Abstract:
Waste is combusted by an incinerator and becomes an ash. The ash is transferred to a melting furnace to be melt therein. The ash contains unburned carbon and the melting at the melting furnace is influenced by an amount of the unburned carbon. The amount of unburned carbon largely depends on a gas temperature at an waste inlet of the incinerator and an waste burn-out point in the incinerator. The waste disposal method, using the incinerator and the melting furnace, comprises the steps of detecting the gas temperature at the waste inlet of the incinerator, detecting the burn-out point of waste combustion in the incinerator, controlling a waste transfer speed in the incinerator and controlling a flow rate of air fed into the incinerator such that the detected temperature and burn-out point remain within repsective predetermined ranges, which in turn brings the amount of the unburned carbon remaining in the ash to a desired value, whereby the melting at the melting furnace is controlled to a desired melting.
Abstract:
A method of stable combustion in a fluidized bed incinerator for burning and decomposing refuse such as municipal wastes while fluidizing them is disclosed. A number of air diffuser tubes are provided inside the incinerator body for fluidizing the refuse and the fluidizing medium. The fluidizing air from the air diffuser tubes is supplied at high speed or low speed from each of the tubes respectively. By alternately forming more and less fluidized areas inside the fluidized bed, the refuse is stably burned. Because of the stable combustion of the refuse, the combustion air ratio can be reduced and the combustion chamber temperature inside the incinerator can be maintained at a high level.
Abstract:
A method of catalystless denitrification for a fluidized bed incinerator to remove NOx generated in burning refuse such as municipal wastes as the refuse is fluidized in a fluidized bed incinerator is disclosed. The refuse is fluidized together with fluidizing medium such as sand along with primary air, and is thermally decomposed and/or burned. The combustible gases generated by pyrolysis are burned with the secondary air blown into the incinerator in a lattice work arrangement. A denitrification agent is mixed in a part of the secondary air, and the NOx present in the combustion gas is removed without using catalysts.
Abstract:
A film formation substrate is arranged such that (i) a base end, in a y-axis direction, of a film-thickness-gradually-diminishing part of a first film overlaps a first film formation region, and (ii) a film-thickness-gradually-diminishing part of a second film is disposed on an outside, in the y-axis direction, of a second film formation region and overlaps the film-thickness-gradually-diminishing part of the first film so as to compensate for a gradually diminished thickness of the film-thickness-gradually-diminishing part.
Abstract:
A vapor deposition source (60), a plurality of limiting plates (81) and a vapor deposition mask (70) are disposed in this order. A substrate spaced apart from the vapor deposition mask at a fixed interval is moved relative to the vapor deposition mask. Vapor deposition particles (91) discharged from vapor deposition source openings (61) of the vapor deposition source pass through between neighboring limiting plates, pass through mask openings (71) formed in the vapor deposition mask, and adhere to the substrate, whereby coating films (90) are formed. The limiting plates limit the incidence angle of the vapor deposition particles that enter the mask openings, as viewed in the relative movement direction of the substrate. In this way, an organic EL element can be formed on a large-sized substrate without increasing the pixel pitch or reducing the aperture ratio.
Abstract:
On a surface of a substrate (3) on which surface a vapor-deposited film is to be formed, a photoresist (13) is formed so as to have an opening in a sealing region including a display region (R1) which sealing region is formed by a sealing resin (11) of a frame shape. Then, luminescent layers (8R, 8G, and 8B) having a striped pattern are formed. Subsequently, the photoresist (13) is removed with the use of an exfoliative solution so as to form the luminescent layers (8R, 8G, and 8B) patterned with high definition.

To inhibit surface reflection of a display device. A display device which includes a reflective electrode layer 110; a partition 118 formed to surround the reflective electrode layer; a layer 120 containing a light-emitting organic compound and formed over the partition and the reflective electrode layer; a semi-transmissive electrode layer 122 formed over the layer containing the light-emitting organic compound; and a coloring layer 162 formed over the semi-transmissive electrode layer. The coloring layer overlaps with the reflective electrode layer and the partition. The partition does not overlap with the reflective electrode layer.
