Title: Characteristic extraction method
Inventor: YONAHA MAKOTO
IPC: G06K9/46
Filed: 1992-07-08
Abstract: PURPOSE:To collectively execute characteristic extraction and a blurring processing and to speed up character recognition by setting segment frames for all characters being recognition objects from an original picture and executing logical filtering, a picture addition processing, a conversion processing by a lookup table and an average value processing using a space filter as to the whole picture. CONSTITUTION:The segment frames as to the whole characters being the recognition objects are decided from the original picture (S1). Distance pictures in four longitudinal/lateral and oblique directions against the whole pictures are obtained by logical filtering and the picture addition processing (S2). The obtained distance picture is converted by the lookup table and a value obtained by raising a dynamic range is obtained as characteristic quantity (S3). The average value processing as to the obtained characteristic quantity is executed by using the spatial filter (S4). Since the characteristic which is blurring- processed is preserved as a density picture, the characteristic is segmented in accordance with the segment frame decided in the step S1 (S5).

Title: Preparation of laminated sheet
Inventor: SUGINO GO
IPC: D06N3/06
Filed: 1985-08-19
Abstract: PURPOSE:To prepare a laminated sheet where a woven or non-woven fabric having good heat and moisture resistance tightly adheres with a plastisol composition, by using a plastisol in which a blocked diisocyanate polymer is added as an adhesive agent. CONSTITUTION:A plastisol composition containing a blocked diisocyanate polymer is applied on a woven or non-woven fabric and is heated and molten at the temp. below the dissociation temp. of the blocked polymer and cooled once if necessary. The plastisol composition is then heated above the dissociation temp. of the blocked polymer just before a sheet or film laminating material is piled up on the coated surface of the plastisol, and the sheet or film laminating material is laminated. The woven or non-woven fabric and the laminated material are pressed under heating while the plastisol composition is heated above the dissociation temp. of the blocked polymer, and thereafter cooled to prepare a laminated sheet. As the material laminated bonded on the composite sheet, natural leathers and woven or non-woven fabrics prepared of nylon or polyester fibers can be used besides synthetic resin sheets or films.

Title: Control device for engine with supercharger
Inventor: KINOSHITA HIROSHI
IPC: F02D17/02
Filed: 1986-08-01
Abstract: PURPOSE:To prevent both the generation of an overrich mixture and the increase of supercharge pressure, by providing a branch intake passage, which introduces auxiliary air, separately from a branch intake passage, which takes out a negative pressure for actuating a valve relieving the supercharge pressure, in the case of an engine when it is in deceleration operation. CONSTITUTION:An engine, if it is placed in an operative condition of deceleration by closing a throttle valve 4, stops the supply of fuel to the second branch intake passage 3b while introduces auxiliary air by receiving an output from a deceleration detecting means 11 to open an auxiliary air valve 12, and the generation of an overrich mixture is prevented. While the closing action of the throttle valve 4 causes a supercharge pressure relief valve device 14 to open its valve main unit 17 by an intake negative pressure, receiving no influence of said auxiliary air, because the valve device 14 is connected with the second branch intake passage 3b, introducing no auxiliary air, through a negative pressure passage 19, and a supercharge pressure is relieved to the upstream side of a supercharger 5. Accordingly, the prevention of an increase of the supercharge pressure, in a word, the prevention of the surging action of a compressor can be promoted.
