Patent EP-0530031-A2 (EP)
Inventor: KRECKEL DOUGLAS A
IPC: G01R29/12
Filed: 1992-08-28
Abstract: An electrostatic voltmeter (100) is provided adjacent to the surface (12) of a photoreceptor belt or drum between, for example, the electrostatographic imaging station (B) and developing station (C). A surface of the photoreceptor is charged at a charging station (A) and the charged area is rotated and stopped adjacent to the electrostatic voltmeter (100). After a predetermined period of time, the surface potential of the charged area is measured by the voltmeter. Additional measurements can be made at subsequent times to determine a dark decay rate of the charged photoreceptor. Surface potentials at other areas adjacent the photoreceptor surface, such as in the development zone, can be determined based on the initial voltage applied to the photoreceptor surface at the charging station and the rate of dark decay. The invention allows for close monitoring/control of the surface potential at one or a plurality of development zones without the need for locating voltmeters within each development zone.

Abstract: In a connector for use in connection between a pair of connection objects (60) having electroconductive inner surfaces, a long pin contact (10) is made of an electroconductive elastic material and has opposite ends which are brought into press contact with the inner surfaces with elastic deformation of a longitudinal intermediate portion of the pin contact. The connection objects are opposite to each other in a first direction (Y) and have a relative position changeable between a first and a second position in a second direction (X) perpendicular to the first direction. The inner surfaces extend in the first direction to define spaces. Before the connection is carried out, the opposite ends are inserted in the spaces, respectively. The opposite ends are loosely fitted in the spaces when the relative position is the first position. When the relative position is changed from the first position to the second position, each of the opposite ends is brought into press contact with each of the inner surfaces at two points different in the first and the second directions.

Abstract: The invention relates to a catalyst that is very suitable for the conversion of a benzoic acid into the corresponding benzaldehyde. The catalyst can be obtained via coprecipitation of a manganese salt, a salt from which an acid support is formed, a zinc salt and optionally a copper salt at a pH between 4 and 10, through calcination, after precipitation, at a temperature of between 300 and 700°C and then, optionally, reduction with the aid of a hydrogen-containing gas mixture. 
     Using such a catalyst the hydrogenation can be carried out at lower temperatures resulting in energy-savings and, hence, cost-savings.

Abstract: In a signal compressing and encoding apparatus, a plurality of A/D converters sample input audio signals synchronously to produce time sample strings. An audio encoding circuit transforms time sample sequences in time/frequency by a frame interval to produce frequency sample sequences. The frequency sample sequences are compressed, encoded and formatted into a frame structure to generate audio bit streams. The audio bit streams are multiplexed by a formatter into a multiplexed bit stream. On the other hand, in a compressed signal decoding circuit, a quantization decoder decodes the frequency sample sequences for each bit stream separated and extracted selectively out of the multiplexed bit stream. A adding result the decoded frequency sample sequences to produce a summing result. The summing result is then transformed in frequency/time by a frequency/time mapping to produce the time sample sequences.

Abstract: In order to ensure that a predetermined bit(s) of a bit sequence to be transmitted is correctly received by a receiver, the predetermined bit is extracted from the bit sequence. The extracted bit is encoded and then combined with a bit sequence which has not been extracted. The combined bit sequence is convolutionally encoded and then transmitted to the receiver. The bit sequence transmitted undergoes maximum-likelihood decoding using viterbi algorithm, wherein the information of the predetermined bit encoding is used to decode the predetermined bit. Subsequently, the encoded predetermined bit portion is extracted and subjected to block decoding.

Abstract: The processing of a first type of interprocess signals and a second type of interprocess signals in a computer system is disclosed. The first type of signals conform to a first signal handling standard and the second type of signals conform to a second signal handling standard. Signal processing operates by determining whether an interprocess signal is a synchronous signal or an asynchronous signal. The interprocess signal 614 originates from a first processing entity 610 and is received by a second processing entity 604. The interprocess signal is processed using signal handling semantics defined by the first signal handling standard if the interprocess signal is an asynchronous signal. Alternatively, the interprocess signal is processed using a combination of signal handling semantics defined by the first and second signal handling standards if the interprocess signal is a synchronous signal.

Abstract: The present invention is to offer a method and an apparatus for improving quality of the combustion fluid for an internal combustion engine etc., which can surely improve the quality of the combustion fluid and reduce the amount of CO and HC in exhausted gas by means of the formation of a great magnetic field in the inner side of the duct for the combustion fluid-supply and the elongation of the irradiation time of magnetic force for the fluid flowing in the duct. 
     In addition, more concretely, the present invention is to offer that at least a pair of magnets are closely attrached between the flow of the combustion fluid facing the same magnetic poles of theirs each other like a sandwich and then that, utilizing the repellency of the lines of magnetic force irradiated from the same magnetic poles, the lines of magnetic force flowing the cross direction to the flow of the combustion fluid are led to the before and behind direction of said flow of the combustion fluid, and result in the elongation of the lines of magnetic force along the direction of the flow of the combustion fluid. As a result, the combustion fluid is exposed in the magnetic field for a long time and the clusters of the fluid is divided into smaller clusters by the unbalance of the electric potential of the fluid molecules. These phenomena trigger the increase of the vaporization of the combustion fluid.
