Abstract: PURPOSE: To significantly reduce NOx in exhaust gas while avoiding the misfire of an engine, and ensure a satisfactory fuel economy. CONSTITUTION: While a fuel is injected into an air-fuel mixture feed port 57 by a first injector 60 to form an air-fuel mixture in the inner part, and supplied into a combustion chamber 14, a swirl is generated in the combustion chamber 14, whereby the air-fuel mixture is laminated to enhance combustibility. This system also has a second injector 62 for injecting the fuel to a first intake port 16. The EGR ratio is controlled according to the operating state of the engine, so that the fuel is injected by the first injector 60 in an area having a high EGR ratio to laminate the air-fuel mixture, and the air-fuel feed port 57 is closed by an opening and closing valve 61 in an area having a low EGR ratio to inject the fuel only by the second injector 62.

Title: Heat exchanger
Inventor: KANEKO SHIYOUZOU
IPC: F28D7/02
Filed: 1982-12-16
Abstract: PURPOSE:To prevent the generation of a thermal stress even when the difference in temperature between a heating gas and a fluid to be heated is large, by a constitution wherein heat exchanger tubes through which the fluid to be heated is disposed in a spiral structure within a flow channel through which a heating fluid flows, and both ends of said tubes are gathered in cylindrical tube gatherings respectively. CONSTITUTION:A fluid to be heated enters an inlet tube gathering 12 from a fluid inlet tube 11 and are distributed in an equal amount to heat exchanger tubes 13. The fluid to be heated, which exchanges heat with a heating gas in the heat exchanger tubes 13, returns to an outlet gathering 14 and goes out from an fluid outlet tube 15. The heat exchanger tubes 13 are disposed in a dual spiral structure in which the tubes ascend spirally through a space between an outer casing 17 and an inner casing 16 and descend after turning the direction in the upper part of the inner casing 16. In this constitution, the fluid to be heated exchanges heat with the heating gas while flowing spirally through the heat exchanger tubes 13, and thus a thermal stress gathered in the heat exchanger tubes 13 is absorbed by the spiral structure, whereby the generation of the stress in the tube gatherings can be eliminated. Moreover, the number of the heat exchanger tubes branching from the tube gathering can be reduced, and thus welded parts can be reduced sharply. Since the structure is simply, it can be adopted for heat exchangers of large and small sizes.

Title: Authenticity, descrimination device for driver's license
Inventor: MIYAZAKI HIROSHI
IPC: G06K7/00
Filed: 1997-08-14
Abstract: PROBLEM TO BE SOLVED: To discriminate more accurately whether or not a license is authentic by having the reverse side irradiated with light and reading an image of the top side. SOLUTION: A driver's license is photographed by a CCD camera 19 (S31). Then an image of the license is photographed again, while an illumination lamp 23 is turned on (S32). Data on the differences between the two image data are image data of only watermark patterns (S33). The right-left pitch and top-down pitch of adjacent watermark patterns are calculated and virtual data to be obtained, when the watermark patterns are arranged in all areas of the image data of the license at the pitches are generated (S34). The virtual data are compared with the data of the differences to decide whether or not the license is authentic according to whether or not the watermark patterns of the address field, name field, photograph field, etc., of the license which nearly match those of the virtual data (S35). Therefore, even when the face photograph of a license is replaced or when the address or name is rewritten, in addition to mention a forgery by color copying, etc., it can be discriminated that such a license has been forged, thus speedily discriminating authenticity.

Filed: 1987-09-02
Abstract: PURPOSE:To obtain the tristimulus values and three-color density of a colored printed material at the same time, by forming a photometer part and a colorimeter part for the printed material as a unitary body by using a light splitting means. CONSTITUTION:Light from a printed material, which is lit with a light source, is condensed through a lens 1. The light is transmitted through an optical fiber 2. Thereafter, the light is split through six pieces of optical fibers 31-36. Three- color density R, G and B are obtained through three-color filters 44-46 having specified transmittances. Tristimulus values X, Y and Z are directly obtained by further using filters 41-43 having specific transmittance distributions without obtaining spectral distribution and spectral reflectance. Thus, the three-color density and the tristimulus values of the printed material can be measured at the same time.

Title: Tungsten-base sintered alloy with high toughness and corrosion resistance
Inventor: KAWAMURA TOSHIO
IPC: C22C27/04
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To produce an alloy excellent in corrosion resistance under high temp. and high humidity and capable of use in this state and also capable of plastic deformation by providing a composition consisting of W and the balance and specifying the ratio between Co and Fe in the combination of Ni, Co, and Fe as the balance. SOLUTION: This W-base sintered alloy is an alloy having a composition consisting of, by weight, 80-97% W and the balance Ni, Co, and Fe, and further, the combination of Ni, Co, and Fe has a composition consisting of 2-60% Co, >0-<5% Fe, and the balance Ni. When the amount of W is less than 80%, deformation is brought about during sintering because the proportion of the binding phase consisting of Ni, Co, and Fe becomes excess, and on the other hand, when it exceeds 97%, the toughness of the alloy is reduced and plastic deformation such as caulking and machining are made difficult. As to the amount of Co in the combination of Ni, Co, and Fe, the corrosion resistance of the alloy is decreased when it is less than 2% and toughness is deteriorated when it exceeds 60%.  Similarly, toughness is lowered when the amount of Fe is 0%, and on the other hand, when it exceeds 5%, there are cases where a partial α-Fe phase is precipitated in the binding phase and corrosion is liable to occur under high temp. and high humidity.
