The present invention provides a toner for developing an electrostatic image which inhibits the filming of a wax on the development sleeve and photoreceptor to obtain a stable image. The present invention also provides a toner for developing an electrostatic image which provides a practically sufficiently wide fixing latitude. The present invention further provides an image formation process for forming a copied image with an excellent dot reproducibility, fine line reproducibility and gradation. A novel toner for developing an electrostatic image is provided, which comprises a particulate toner containing a polyolefin wax and a modified polyolefin wax, wherein the average diameter of wax particles dispersed in the particulate toner is not more than 0.5 .mu.m and the amount of wax exposed on the surface of said particulate toner is from 40 to 65% by weight. The particulate toner may comprise a finely divided magnetic powder in an amount of from 30 to 70% by weight. The content of modified polyolefin wax in the particulate toner is preferably greater than that of polyolefin wax.

Abstract:
A blood collecting apparatus includes a measuring device provided with a sensor for measuring the amount of collected blood when blood is collected into a blood container, and a controller for calculating the amount of collected blood based on an output y of the measuring sensor. The output y is a function of an n-times measured weight w of collected blood such that y=aw+b, wherein a and b are constants characteristic of the measuring sensor. The controller detects the output yi of the measuring sensor in n+1 units of respective known amounts wi of collected blood, and corrects the constants a and b on the basis of such detected data. The controller, moreover, automatically detects the output yO of the measuring sensor every predetermined cycle in a state where the measured weight w of collected blood is zero, and corrects the constant b of the function y=aw+b on the basis of such detected output yO.

Abstract:
A key action mechanism incorporated in an upright piano is accompanied with a repetition mechanism having a repetition lever rotatably supported by a butt and pushed by a jack after an escape from the butt for producing a gap between a leading end thereof and a back check, therefore, the butt and, accordingly, hammer assembly can rotate backwardly over a predetermined angle due to the gap, after the striking or after the escape of the jack, and, as a result, the hammer assembly is prevented from double-strike.
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:
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.
