Filed: 1992-07-07
Abstract: A thermal type flowmeter for measuring a flow rate of a fluid which is equipped with a thermo-sensitive resistor provided within a fluid passage and arranged to heat when being energized. The flowmeter includes an electric power adjusting element provided in series to the thermo-sensitive resistor so as to adjust an electric power to be supplied to the thermo-sensitive resistor in accordance with a current inputted to its input terminal and a constant current source circuit connected to said input terminal of the electric power adjusting element to supply a predetermined constant current to the input terminal of the electric power adjusting element. A control circuit outputs an adjustment signal to adjust an energization electric power to the thermo-sensitive resistor so that the thermo-sensitive resistor has a predetermined temperature, and a current adjusting circuit connected to the input terminal of the electric power adjusting element divides the constant current from the constant current source circuit in accordance with the adjustment signal from the control circuit so as to adjust the input current to the electric power adjusting element. This arrangement can reduce the minimum operating voltage for the flowmeter because the input current of the electric power adjusting element can be obtained from the constant current source circuit.

Abstract: The invention relates to a method for the search of a motion vector (MV) for a video signal in hybrid coding where the temporal redundancy of the image is removed by DPCM prediction and a resulting prediction error is converted by a transform operation into transform-domain coefficients and transmitted to a decoder in the form of coefficients. To avoid the problems caused in hybrid coding by motion vectors found by the commonly used block matching method, a first operation approximating the transform of the actual hybrid encoder is applied (35) to a difference image produced by an image block corresponding to a motion vector candidate to be tested in the search of the motion vectors, and the coefficients produced by said operation are used to approximate a number of bits required to code the transform coefficients, and a block minimizing said number of bits is selected from within a selected motion vector search area as the prediction block.

Abstract: An ink-jet pen (22) for storing at below-ambient pressure has an orifice (54) formed therein for providing air bubbles to prevent the back pressure from rising above a level that would cause malfunction of the pen (22). The amount of air drawn into the reservoir (24) is restricted by the reservoir ink (31) that covers the orifice (54) whenever the pen (22) is in an upright position. The valve (20) operates to occlude the orifice (54) whenever the pen (22) is moved into a position, such as inverted, where the reservoir ink no longer covers the orifice (54). The occlusion of the orifice prevents the unrestricted flow of ambient air into the reservoir (24) that would otherwise eliminate the required back pressure in the reservoir (24). The valve includes a sealing liquid (68) selected so that the liquid occludes a passage (60) between the orifice and ambient air without flowing through that passage (60).

Abstract: A method for evaluting the virus removing capability of a porous polymericic membrane comprises filling a space on one side of the membrane of the module with a liquid, supplying another space on the other side of the membrane with a gas, terminating the supply of the gas when the transmembrane pressure on the membrane reaches a predetermined level (Ph) (higher than a level at which non-visible bubbles begin to form but lower than level at which visible bubbles begin to form), allowing the module to stand to thereby cause the transmembrane pressure to be lowered, and measuring the transmembrane pressure lowering (ΔP), a predetermined period of time after the termination of the supply of the gas (Δt). A correlation between Δp and the log virus rejection coefficient, φ is easily established (fig. 3) and suitable values for Ph can be obtained by construction using a graph of the transmembrane pressure v. gas flow rate (fig.1).

Abstract: An object image display device which changes and displays the image of an object such as an animal or a building. A display (2) displays an object image including a combination of patterns of the parts of the object. The pattern of at least part of the object image displayed on the display (2) is successively changed to a different part pattern of the same at least part in response to the keying operation of keys (4, 6). Thus, the display (2) displays the object image such that the at least part of the object image successively moves. The user is able to set a shape to which the object image is changed and the timing of changing the object image. Each time the object image is changed, a voice corresponding to the aspect of change of the object image is output sequentially to the outside. Externally inputting a voice into the device changes at least a part of the object image displayed at present in accordance with the contents of the input voice.

Abstract: Feature classification using a novel supervised statistical pattern recognition approach is described. A tree-like hierarchical decomposition of n-dimensional feature space is created off-line from an image processing system (80). The hierarchical tree is created through a minimax-type decompositional segregation of n-dimensional feature vectors of different feature classifications within the corresponding feature space. Each cell preferably contains feature vectors of only one feature classification, or is empty, or is of a predefined minimum cell size. Once created, the hierarchical tree is made available to the image processing system (80) for real-time defect classification of features in a static or moving pattern. Each feature is indexed to the classification tree by locating its corresponding feature vector in the appropriate feature space cell as determined by a depth-first search of the hierarchical tree. The smallest leaf node which includes that feature vector provides the statistical information on the vector's classification.

Abstract: The invention concerns a method and a device in the drying of a paper web (W), wherein, after the press section (20) of the paper machine, the paper web (W) is dried in a number of successive groups (R 1 ...R N ;R S ) with single-wire draw, in which groups the contact-drying cylinders (10) are placed in the upper row and the reversing suction cylinders (11) or the equivalent suction rolls in the lower row or in equivalent diagonal or vertical rows. From the side of its lower face, across the entire length of the dryer section, the paper web (W) is dried by means of contact-drying cylinders (10). The paper web (W) is passed as a closed draw from one group (R 1 ...R N ; R S ) with single-wire draw to the next group, and the paper web (W) is guided, while it is placed on the drying wire (15) at the side of the outside curve, by means of the reversing suction cylinders (11) with a curve radius D 2 /2, which is chosen in the range of D 2 /2 ≈ 250...1000 mm.
