Title: Air-fuel ratio control method for internal combustion engine
Inventor: YANO TORU
IPC: F02D41/12
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To prevent the increase of an NOX discharge amount when the target air-fuel ratio of an internal combustion engine having a three-dimensional catalyst is varied from lean condition to soichiometeric condition. SOLUTION: When a target air-fuel ratio is switched from lean (or fuel cut) to stoichiometric, during a time in which a given rich target time elapses, a target air-fuel ratio forms a given rich target air-fuel ratio being further rich than a stoichiometric air-fuel ratio. Thereafter, a target air-fuel ratio is transferred to a stoichiometric air-fuel ratio. A rich target time and a rich target air-fuel ratio are decided based on a continuance time of the lean operation, an engine load, and the an engine speed so that O2 stored in a three-way catalyst during lean operation is reliably discharged. By bringing a target air- fuel ratio into a state to be temporarily further rich than the stoichiometric air-fuel ratio is.  O2 stored in the three way catalyst during lean operation is rapidly discharged and NOX controlling capacity of the three way catalyst is restored to prevent discharge of NOX to the atmosphere.

IPC: G01C11/06
Filed: 1993-03-27
Abstract: PURPOSE:To perform proper matching, and thereby enable the cubic surface shape of a subject to be detected by constituting a correlation window deforming section so as to be provided, which can deform a corresponding correlation window in size and shape based on the difference in position between the picture element of a first photographic image and the picture element corresponding to the picture element of a second photographic image. CONSTITUTION:The size and the shape of a corresponding correlation window 36 is deformed based on the difference in position between each position (i1-j1) through (i5-j5) of the picture elements P11 through P15 of a first photographic image 31 and each position (11-m1) through (15-m5) of the picture elements P21 through P25 corresponding to the picture elements P11 through P15 of a second photographic image 32. This constitution thereby allows the corresponding correlation window 36 to be deformed so as to be formed into the second photographic image 32 which can be approximately considered to be the deformed image of the first photographic image 31. Therefore, the similarity of an image within a correlation window can be enhanced as compared with a corresponding correlation window identical in size and shape to a reference correlation window. By this constitution, proper matching can be performed, and the shape of a cubic surface can be properly detected.

Title: Ti silicide thin film forming method
Inventor: ASAI KOSUKE
IPC: H01L21/285
Filed: 1995-04-18
Abstract: PURPOSE: To efficiently form a C54-phase even on a microinter-connection by growing Ti like islands on a single crystal Si substrate or polycrystalline Si, heat annealing it to form a silicide, and heat annealing again. CONSTITUTION: A Ti 2 is grown like islands on a Si substrate 1.

Filed: 1980-07-04
Abstract: PURPOSE: To save the energy for air-conditioning of house by a method wherein the heat of the outside air is automatically accumulated in gravles having a large heat capacity and released into room as occasion calls.  
     CONSTITUTION: In the use for cooling during the summer season, when the difference between the temperature detected by a sensor 22 in gravel layer and the temperature detected by a sensor 23 installed outside the house reaches to the predetermined value during the night, the motor 15 of a ventilating fan rotates to take in the chilly outside air through a window 13 and to discharge through a window 14 into the open air. In the meantime the temperature of the gravel layer 1 lowers to the outside temperature and when the difference between the temperature detected by the sensor 22 and that by the sensor 23 becomes null, the motor 15 stops. And in the daytime, when the cooling is required due to the room temperature rise, by turning a proper switch ON, a ventilating fan 17 rotates to take in the outside air which is cooled by passing through the gravle layer 1 getting cold during the night down to the outside temperature, into the room 5. The air within the room 5 passes through windows 18 and 19 equipped with ventilators to drive out the hot  air stagnated in the ceiling through windows 20 and 21 to the outside.

Filed: 1994-05-02
Abstract: PURPOSE:To provide a novel side step structure which can be used commonly for an automobile having a wide vehicle body and an automobile having a narrow vehicle body, without lowering the sale value thereof. CONSTITUTION:A side step body is composed of separate bodies, that is, a planar side step body 9 defining a foot face, and a longitudinal wall defining member 10 which can be attached at its lower edge to the vehicle body side end part of the side step body 7. The longitudinal wall defining member 10 is curved. Accordingly, if the longitudinal wall defining member 10 is attached to the side step body 9, one 10a of its two surfaces being facing outward, the upper end part of the longitudinal wall defining member 10 overhangs outward. Meanwhile if the longitudinal wall defining member 10 is attached to the side step body 9, the other one 10b of its two surfaces facing outward, the upper end part of the longitudinal wall defining member overhangs inward. Since the longitudinal wall forming member 10 can be attached to the side step body 9, either of the front and rear surfaces thereof facing outward, the longitudinal wall forming member 10 can constitute two kinds of side steps 8 which are used respectively for a large width vehicle body and a narrow width vehicle body.

Title: Crank chamber compression type two cycle engine
IPC: F02N19/00
Filed: 1992-03-19
Abstract: PURPOSE:To prevent generation of deterioration of startability caused by presence of high viscous oil by forming a discharge port on a sliding surface of a cylinder, supplying low viscosity fluid onto the sliding surface from the discharge port when an engine temperature is not more than a preset value at the time of engine starting, and thereby reducing sliding resistance. CONSTITUTION:An exhaust port 35, a main scavenge port 41b, an auxiliary scavenge port 41c, and a discharge port 87 are opened to a sliding surface 12 of a cylinder 11. The discharge port 87 is faced to a crank chamber 33 during a very short time near a top dead center, and faced to a skirt portion of a piston 21 almost all of the other time. A low viscosity fluid pump 71 is operated for suctioning fuel from a fuel tank 61 through a low viscosity fluid passage 68. The fuel is discharged through a solenoid valve 81, the low viscosity fluid passage 68, and the discharge port 87 to the sliding surface of the cylinder 11. Signals are input to an ECU 51 from a starter sensor 53 and an engine temperature sensor 57. When an engine temperature is a specified value or lower at the time of engine starting, resistance on the sliding surface is reduced by discharging the fuel, that is, the low viscous fluid.

Title: Rotary cutting tool
Inventor: SHIBUKI KUNIO
IPC: B23C5/18
Filed: 1984-05-10
Abstract: PURPOSE:To improve the cutting performance and spread the use of a cut material by coating the surface of a share-point part with a hard coated layer with high adhesion strength through physical evaporation method. CONSTITUTION:The share-point part 3 of a rotary cutting tool 1 is made of the superhard alloy such as WC, TiC, TiN, etc., and the surface part of a basic material having WC particles is coated by a hard coated layer 4 prepared through PVD method, and said coated layer 4 is made of TiC, TiN, Al2O3, etc., and formed as a single layer or the double layer consisting of two layers or more. The reason of adopting the PVD method is that since the share-point part 3 is brazed onto a shank part, the low-temperature coating treatment below a brazing temperature is suitable, and a kind of diffusion layer 5 having a thickness of 0.05-1mum is formed onto the surface side on the interface between the hard coated layer 4 and the surface part of the share-point part 3 corresponding to the underground. Therefore, the adhesion strength between the share-point part and the hard coated layer 4 is increased, and exfoliation of the hard coated layer 4 is eliminated, and high-speed cutting is enabled, and the cutting life can be prolonged, and the tool can be adopted for the cutting of hardened steel.
