Abstract: The present invention provides a compact air induction system for an internal-combustion engine in which an air inlet section, a collection section and the intake port section for a plurality of cylinders of the internal-combustion engine are formed adjacent to each other and connected directly or through a partition wall. A control unit for controlling the engine is mounted in the passage at the downstream of the air inlet section.

Abstract: An ink jet recording material is constituted by a support and a recording layer on the support, in which a plurality of recording layer may be provided. At least one recording layer contains colloidal particles and a water-soluble resin. In order to produce the ink jet recording material, a sticking or adhesive interlayer is provided on a support, and a recording layer including at least one layer is superposed on the interlayer. At least one of the at least one layer of the recording layer contains colloidal particles and a water-soluble resin, and the recording layer is coated and formed on a forming material. Then, the forming material is peeled from said recording layer.

C. to 120.degree. C., and a longitudinal tensile elastic modulus of 50 MPa or less and a transversal tensile elastic modulus of 100 MPa or less at 120.degree. C.

Abstract: The invention discloses a wet process flue gas desulfurization apparatus and method for use with a tank oxidation system. The apparatus comprises: an absorption tower having a slurry containing a calcium compound which is supplied to the bottom tank, a circulation pump for feeding the slurry in the tank into a flue gas inlet in an upper part of the absorption tank to be in contact with flue gas, and air feed means for feeding air for oxidizing into the tank, thereby absorbing and oxidizing sulfur dioxide in the flue gas by the slurry to obtain gypsum as a byproduct, wherein a vacuum type belt filter is disposed along an outer surface of a side wall of the absorption tower, and part of the slurry that is discharged from the circulation pump is led into the belt filter to be dehydrated, thereby separating and recovering gypsum.

Abstract: An encoding (or decoding) method, by which raw data of 1 line is converted into, for example, modified Huffman (MH) code (or MH code is converted into raw data) by obtaining a cumulative run-length code every transition point, at which there occurs a transition or change between a run of white pixels to another contiguous run of black pixels, from the beginning of the line and then converting the cumulative run-length code to the MH code (or converting the MH code to the cumulative run-length code). The cumulative run-length code is defined by both of data, which indicates that a pixel of a run just prior to the transition point is black or white, and data representing a cumulative run-length of the run up to the pixel thereof just prior to the transition point. Thus, an encoding or decoding processing can be performed at a high speed.

Abstract: The support sheet for photographic printing paper of the present invention includes a substrate paper sheet, a front surface composite resin coating layer formed on the front surface of the substrate paper sheet and including an inside cured resin layer and outermost cured resin layer including, as a main component, an electron beam-curing product of electron beam-curable unsaturated organic compound, and a back surface resin coating layer formed on the back surface of the substrate paper sheet and including a film-forming synthetic resin, and is produced by a process including the steps of forming at least one inside coating liquid layer including an electron beam-curable unsaturated organic compound on the front surface of the substrate paper sheet;separately forming an outermost coating liquid layer containing an electron beam-curable unsaturated organic compound on a shaping surface and applying thereto a first electron beam irradiation to provide an outermost cured resin layer;superimposing the outermost

Abstract: A Viterbi decoding method, in which consecutive input data bits Q.sub.6n .about.Q.sub.1n are first converted into consecutive code bits Q.sub.6n .about.Q.sub.3n Y.sub.2n Y.sub.1n Y.sub.0n at a time instant n by use of a Trellis encoder. Then, a branch metric, which is a minimum Euclidean distance between a reception signal point and each of signal points (namely, Trellis codes Q.sub.6 .about.Q.sub.3 Y.sub.2 Y.sub.1 Y.sub.0) in a signal space diagram, corresponding to each of eight states 0 to 7 and a corresponding signal point are obtained. Further, a sum of the branch metric corresponding to each state and a corresponding path metric at a time instant (n-1), which is a sum of corresponding branch metrics since a time instant 1 to the time instant (n-1) is calculated. Then, the path metric corresponding to each state is updated by replacing it with the calculated sum of the corresponding branch metric and the corresponding path metric obtained at the time instant (n-1).

Abstract: A projection-type image display device includes a transmissive image display panel having a matrix of pixels arranged at different pitches in different directions perpendicular to each other, and a planar microlens array for converging light emitted by a light source onto the transmissive image display panel. The planar microlens array comprises a substrate and a matrix of microlenses disposed on the substrate for converging the light onto the pixels, respectively, each of the microlenses being of an oblong shape. Each of the microlenses may have a longitudinal axis inclined with respect to an axis of the matrix of pixels to cover the pixel aperture of one of the pixels. The oblong shape of each of the microlenses may be composed of a pair of spaced identical semicircles and a rectangle interconnecting the identical semicircles and having sides of the same length as the diameter of the semicircles.
