Abstract:
In an image forming apparatus using a speed reduction device with elastic bodies, the rotational speed of a motor is reduced by the speed reduction device using the elastic bodies. The rotational speed of the speed reduction device is detected by an output rotation sensor, and the rotational variation components contained in the rotational speed are extracted by a high path filter. A voltage comparator determines whether the rotational variation components reach a predetermined voltage value or lower, and causes an image writing control unit to wait to write image data on a rotating drum until the rotational variation components reach the predetermined voltage value.
Abstract:
In a conductive roller having a conductive substrate, a conductive elastic layer and a conductive cover layer, the conductive cover layer is formed of a seamless tube containing a thermoplastic polymer, the surface of the conductive roller is coated with an inorganic compound the particle surfaces of which have been subjected to hydrophobic treatment, and the roller having been coated therewith has a glossiness of from 7.5% or more to less than 22.0%. This conductive roller can make toner and external additives less adhere to the roller surface, can prevent the faulty images due to the adhesion of photosensitive-member abrasion dust and can well perform charging in the image reproduction from the initial stage to the last.
Abstract:
An IC token for use in a machine such as a gaming device has an IC tag centrally located within a ring of electromagnet wave-absorbing material. The ring is designed to permit a peripheral attachment to the edges of the IC tag with appropriate molding dies to encapsulate the IC token in a resin. The IC token is adapted to be read by a selection device having an antenna along an inclined guide rail while eliminating the possibility of crosstalk between tokens.
Abstract:
A miniaturized coin hopper device is provided so as to have a lower height. The device has an electric motor which is arranged such that the projection end of a rotated axis thereof is located at a lower side. A first gear is fixed on this projection end of rotated axis. A disk for discharging coins one by one is provided at the bottom of a hopper which stores the coins. A second gear rotates this disk. A gear train connects this second gear and the first gear. The problem of a true coin being disbursed when a pseudo-coin was stored in a hopper device and the return button was pushed is also addressed. A distinguishing element checks the money kind of a deposited coin. A reserve temporarily holds the coin distinguished by this distinction element. A storage for coins of same money kind and a disbursing element is provided for the the coin in this storage to return the coin reserved in the temporary reservation. A device is also provided to distribute the coin reserved in said temporary reservation to the storage.
Abstract:
An authentication apparatus compares a value of correlation between inspection characteristic data of an organism acquired from the organism to be inspected and reference data associated with a predetermined organism with a predetermined threshold associated with said predetermined organism to perform authentication on whether said organism to be inspected is said predetermined organism or not.
Abstract:
A digital-signal processing apparatus in which the efficiency of processing data can be prevented uniformly. The apparatus includes: an extracting unit that extracts a part of real data input; a selecting unit that selects a data size from similar data sizes falling in a range, in accordance with the size of the extracted data, which is a reference value, and with data-decomposing conditions described in an algorithm that realizes fast Fourier transform; and an operation unit that decomposes the data extracted and having the selected size into data items, in accordance with the data-decomposing conditions, and that performs Fourier transform on each data item, thereby effecting convolution on the data item.
Abstract:
An image processing apparatus can improve the image quality of images. The image processing apparatus includes a parameter extracting unit that extracts a parameter for expressing the degree of sharpness of each image when a plurality of images are obtained with different degrees of sharpness by decomposing an original image, using input image data, a parameter adjusting unit that adjusts the parameters of the images extracted by the parameter extracting unit so as to make the original image sharp and a generating unit that generates the original image on the basis of the parameters of the images adjusted by the parameter adjusting unit.

Image processing method and apparatus of same are provided. An image processing method includes a first step of processing first image data obtained by capturing an image of a predetermined region including a blood vessel pattern of a biological entity so as to enhance the image corresponding to the blood vessel pattern in the first image data to generate second image data; a second step of processing each pixel data composing the second pixel data generated at the first step to generate index data indicating an average value of pixel data of pixels around a pixel corresponding to the pixel data or a value obtained by leveling pixel data of the surrounding pixels; and a third step of subtracting the index data generated at the second step corresponding to the pixel data from each pixel data composing the second image data generated at the first step to generate third image data.
Abstract:
The present invention discloses the use of ethercarboxylates for lubricating textile fibres, preferably spinning fibres. These ethercarboxylates have the general formula (I) R—(OCH2CH2)n—O—CH2COOX (I) where: R represents a C6-C22 aliphatic hydrocarbon chain, saturated or unsaturated, linear or branched, n is a number between 0.3 and 50, X is hydrogen, an alkali metal, an ammonium cation, an alkanolammonium cation or a C6-C22 alkylammonium cation. In addition, the present invention provides a process for lubricating textile fibres that consist of placing in contact these textile fibres with ethercarboxylates of general formula (I).
