Abstract: PURPOSE: To safety open/close a folding door by actuating a drive unit to simultaneously apply swinging force and tensile force along a guide rail to a door body at an end part among plural door bodies composing a folding door. CONSTITUTION: As a person gets closer in a totally closed condition of a folding door, a drive unit is actuated, a sprocket is rotated, a wire 13 around a follower pulley is pulled, and a pulley 22 is rotated in a direction of an arrow C. Next, rotation torque of the pulley 22 is increased by a gear to be transmitted to a wide door body 3, and simultaneously as the door body 3 is rotated in the direction of the arrow C, a narrow door body 2 is rotated in a direction of an arrow D. A gear box is then once moved in the opposite direction to an arrow E till a hinge 4 gets over a line L connecting a shaft bearing 6 to a swing center P of the door body 3. After the hinge 4 gets over the line L, the gear box moves along a guide rail 14 in the direction of the arrow E, so the door starts opening.

Title: Fuel supply device for internal combustion engine
Inventor: OYAMADA TETSUYA
IPC: F02M55/02
Filed: 1986-03-24
Abstract: PURPOSE:To make it possible to maintain a high pressure over a wide load range, by connecting a closed container disposed therein a relief valve which opens a fuel pressure exceeding a predetermined value, to a fuel supply pipe through a branch pipe. CONSTITUTION:A fuel from a fuel tank 8 is pressurized by a fuel pump 2, and is then fed into a fuel injection valve 9 through a fuel supply pipe 3 with a given timing before the fuel is injected into a combustion chamber 1. At this time a part of the fuel in the fuel supply pipe is fed into a relief valve 6 disposed in a closed container 5 through a branch pipe 4. Fuel discharged from the relief valve 6 is all trapped in the closed chamber 5 and is then returned into a fuel supply tank 8 through a return pipe 7. Therefore, during normal load operation which is used for the most occasions, the pressure of fuel injection may be made to approach an allowable highest pressure as possible as it can, and therefore, it is possible to obtain a satisfactory cycle efficiency and combustion efficiency.

Title: Manufacture of brake frictional material
Inventor: MIYAKE SHINGO
IPC: C08J5/14
Filed: 1988-03-18
Abstract: PURPOSE:To improve and stabilize braking characteristic by alternately laminating inorganic fiber materials and gap materials in a direction perpendicular to the longitudinal direction of the fiber materials, pre-molding by compressing, cutting it in the laminating direction, baking and employing the cut face as a frictional face. CONSTITUTION:Phenol resin, graphite, barium sulfate, etc., are mixed and agitated to form a gap material A. After the material A is filled in a die, steel fiber S is laid horizontally thereon, and the operations are repeated to form a molding material B. After it is pressed in a direction of an arrow F to be pre-molded by compression, the molded piece C is cut in a predetermined thickness in the laminating direction, and bonded on a lining metal 1 with a phenol resin adhesive so that the fiber S and the upper face 1A of the metal 1 cross perpendicularly. The piece C is cured by baking, and brought into close contact with the metal 1. Thus, the frictional face of the frictional material can be set to a direction perpendicular to the longitudinal direction of the fiber material, and the fiber S is not peeled from a frictional material body, thereby preventing it from needless wear.

Filed: 1993-03-24
Abstract: PURPOSE:To improve productivity and the quality of processed parts by irradiating the surface of a substrate or any layer of laminated layers with UV laser beams to induce abrasion, thereby forming ruggedness on the surface. CONSTITUTION:The surface of the substrate 1 is irradiated with the UV laser beams L to induce the abrasion, by which the recessed parts B are formed on the surface.

IPC: H04K1/02
Filed: 1988-03-22
Abstract: PURPOSE:To constitute with a simple hardware and to make hard to clarify a content by constituting a transmission part with two switches, (n) kind of a noise generator and an adder, constituting a reception part with the (n) kind of a noise generator, two switches, an adaption filter to assume a reception period noise signal and an echo canceller and executing a privacy transmission. CONSTITUTION:A call signal (a) which is an input signal from an input terminal 101 is inputted to an adder 13. The adder 13 adds a periodic noise N from a noise generator 1-1 to this input signal (a) and sends out to a transmission path 33. Consequently, a transmission signal (b) from the adder 13 is turned to be the signal (a) + N and be an ununderstandable privacy when the periodic noise N is large. This signal (a) + N receives the influence of this transmission path 33 in the transmission of the transmission path 33, when it reaches a transmission equipment 32, turned to be a signal f(a) + f (N) and inputted to a subtracter 24. The subtracter 24 erases only the signal f (N) which is the reception periodic noise signal (c) from the signal f (a) + f(N) which is a reception signal (d). Next, only the call signal f (a) is reproduced.

Abstract: PURPOSE: To cast the slab near the producing limit of air bubbles on its surface without producing  any air bubbles by continuously measuring the oxygen density of the molten metal poured in a  mold and controlling deoxydation operation based on the measured value thereby obtaining a  desired degree of deoxidation on the molten metal surface in the mold.   
     CONSTITUTION: At the time of pouring molten steel 3 from a ladle into a mold 2 through a tundish 1, the electrode 4 combined with standard electrode and solid electrolyte is dipped in the  molten steel 3 in the mold 2. Further, the pole (counter pole) 6 to be detected is provided near  the molten metal 5 surface and a potentiometer 7 and connecting parts 8, 8 are mounted between  both poles 4 and 6 to form an oxygen concentration cell. The oxygen density in the molten steel  at the pouring into the mold 2 is continuously measured by this battery. Next, this measured value is kept supervised and when the measured value exceeds the air bubble production limit, a wire- form deoxidizer 9 is added from an adding machine 10 so that the degree of deoxidation (for  example, 30W40ppm) which is closed to the air bubble production limit and at which no air bubbles are formed is obtained at the molten metal surface 5. This method enables the reduction of  the decarbonizer amount as well as the nozzle clogging and nozzle burnout.

Title: Vehicle running position estimation system
Inventor: MURAKAMI KUNIO
IPC: G01C21/20
Filed: 1994-04-04
Abstract: PURPOSE:To enable pattern matching of suitable length according to road condition. CONSTITUTION:In pattern matching distance, weighing coefficient alpha3 of pattern matching correlation value of longer distance is made greater as vehicle speed increases. As vehicle speed decreases, weighing coefficient alpha1 of pattern matching correlation value of shorter distance is made greater, and as for middle distance, weighing coefficient alpha2 of middle distance is made greater. Thus, on superhighways, etc., the distance compared in pattern matching is longer, so, even at a gentle curve, pattern matching with a running trace is accurately done, so that, on which one of nearby multiple roads a vehicle is running is accurately estimated. Since in running in urban district, etc., the distance compared in pattern matching is shorter, so, even at a small curve, it is sufficiently reflected an pattern matching.
