Patent EP-0404067-A2 (EP)
Inventor: YUKI HIROKAZU FUJI PHOTO FILM
IPC: B01D19/00
Filed: 1990-06-19
Abstract: A method of dissolving a powder material is disclosed in which the material is wholly dissolved and the existence of bubbles in the resultant solution is greatly minimized. An agitating blade stirs a liquid in an air-tight tank while the powder material is inserted into the liquid. The pressure is then reduced in the tank causing large bubbles to swell. The bubbles are destroyed by the agitating blade. The pressure reducing operation is then turned off so that the bubbles do not leave the tank through a pressure reduction port. The pressure reducing operation is then repeated a number of times to dissolve the powder material and to destroy bubbles.

Abstract: A data processor decoding and executing a train of instructions including a plurality of sets of an instruction code field (a) and a corresponding addressing field (b). The data processor includes a decoding unit (1,2) for decoding the instruction code field and the corresponding addressing field, and outputting an instruction tag information (A) and an addressing information (B1), respectively, in response to a control signal (C) generated at a predetermined frequency; a holding unit (3) for holding the addressing information fed from the decoding unit, and outputting a holding result (B2) in response to the control signal; and a detecting unit (4) responsive to the instruction tag information, addressing information and holding result. The detecting unit effects a judgement of whether the instruction tag information indicates that it is an instruction to check undefined addressing of the addressing field decoded in the preceding stage or in the present stage, and detects the undefined addressing based on a result of the judgement. As a result, it becomes possible to check undefined addressing prescribed for each instruction without lowering instruction execution performance of the data processor.

Abstract: Semiconductor memory having non-volatile memory cells which can be programmed and erased electrically (EEPROM) by means of tunnel current and which contain a floating-gate transistor. The memory cells are arranged in memory cell groups each containing n rows and in m columns, n cells being connected in series and this serial connection forming the bit line for the columns of a cell block, and the control gate of m adjacently situated memory cells being common to a row of the cell block and forming the word line for the row of the memory cell group. The floating gate does not extend over the entire width of the channel so that, in each memory cell, a parallel transistor is formed which is connected in parallel with the floating-gate transistor, is controlled only by the control gate and is conductive for every unselected cell during reading. This solves the problem of over-erasing even with short access times without an additional access transistor being necessary.

Abstract: The purpose of this invention is the acquisition of the means for obstructing the accident which makes it impossible to start an internal combustion engine driven by a cell motor resulting from the excessive discharge of the battery for driving it. 
     In this invention, the battery which is as large as the conventional one consists of two equal size small ones. Its terminals consist of a common minus pole one and two independent plus pole ones. The generator charges the battery under constant voltage. Its charging current reaches the said plus pole terminals passing two diodes respectively. The cell motor is driven through a magnetic switch device. The said two small batteries alternate in energizing the loads including the cell motor and the relay for it simultaneously through the said two plus pole terminals respectively. Every time the cell motor starts the engine once, the said two small batteries alternate in functioning resulting in ensuring the engine start.

Abstract: A motion detection signal delivered from a mixer (8) is output through a series circuit of a maximum value calculation portion (16) and a minimum value calculation portion (23). In each of the calculation portions (16, 23), calculation is performed within a block of 3-dot x 3-line. Missing of motion detection is prevented from occurring in the maximum value calculation portion (16) because the motion detection signal of the pixel under attention is calculated therein with the values within the block and, accordingly, the motion detection signal is expanded in the horizontal and vertical directions. A detection spread to a still picture portion occurring in the calculation portion is suppressed in the minimum value calculation portion (23) because, when surrounding motion detection signals therein are lower than the motion detection signal of the pixel under attention, the motion detection signal of the pixel under attention is replaced with the lower value. With the described arrangement, the missing of motion detection is advantageously prevented without inviting the detection spread to a still picture portion.

Abstract: A technique for enhancing connected and degraded text is presented. The enhancement process comprises filtering a scanned image to determine whether a binary image value of an image pixel should be complemented, determining whether complementing the value of the pixel reduces the sharpness of wedge-like figures in the image, and complementing the binary value of the pixel when doing so does not reduce sharpness. Image preprocessing may also provide a line adjacency graph (LAG) based on a set of image pixels and the removal of a path from a LAG when the path is located either at the top or bottom of the set of image pixels and is of degree (1,0) or (0,1), respectively, and connected to a junction of the LAG. An optical character recognition process may be combined with preprocessing and may comprise determining primitive strokes in a scanned image, segmenting the scanned image into sub-character segments based on the primitive strokes, identifying features which characterize the sub-character segments, and comparing identified features to stochastic models of known characters and determining an optimum sequence of known characters based on the comparisons through the use of Viterbi scoring and level building procedures.

Abstract: A procedure with which the speed of revolution of a wheel can be determined during the braking process of a motor vehicle is described, which motor vehicle has, in addition to at least one speed of revolution-sensed wheel, at least one further non-speed of revolution-sensed wheel and means for determining the brake pressure. For this purpose, the braking process is subdivided into a plurality of time intervals in which in each case the relative value is formed from the braking work and the kinetic energy of the motor vehicle, and in a first time interval the size of the non-speed of revolution-sensed wheels with respect to the braking work is defined. Furthermore, the ratio of the relative value of this time interval to the relative values in the other time intervals is formed and the average value of the speed of revolution of all the non-speed of revolution-sensed wheels is determined in the further time intervals from the ratio of the relative values.
