Patent JP-H09217642-A (JP)
Title: Control device of internal combustion engine
Inventor: TAMURA HIROSHI
IPC: F02D41/12
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To stably display exhaust gas purifying performance of a catalyst for a long period of time. SOLUTION: A throttle opening TA is not totally closed for a certain period of time and it is controlled to be a minimum throttle opening TAmin where misfire is not caused even when an acceleration opening PA is totally closed in the case when catalyst temperature Tcal is high temperature (Tcat>700 deg.C). Consequently, a fuel cut condition is not established and fuel cutting is not practiced in the case when the catalyst temperature is high temperature.  Accordingly, it is possible to prevent oxidization and deterioration of a catalyst as high density oxigen flows into the catalyst in a high temperature state, and it is possible to prevent discharge of unburnt gas by stabilizing combustion of fuel while preventing misfire at the time of deceleration at the time when the catalyst is high temperature and to restrain rise of the catalyst temperature by preventing a phenomenon that the unburnt gas afterburns in the high temperature catalyst at the time of deceleration by controlling the throttle opening TA at the time of totally closing an accelerator to the minimum throttle opening TAmin where the misfier is not caused.

Filed: 1984-02-15
Abstract: PURPOSE:To obtain a tracking control signal from a simple circuit, by producing a difference frequency signal component necessary for producing the tracking control signal from a reproduced pilot signal only. CONSTITUTION:A pilot signal is reproduced by a head 21 and inputted in an analog operation circuit 26 through a change-over switch 20, regenerative amplifier 22, AGC circuit 24, and LPF25. The sum of a reproduced signal from a reproducing track and pilot signals from its adjacent two tracks is squared at a squaring circuit and the difference frequency signal of the pilot signal from a main reproducing track and pilots signals from the right and left adjacent tracks is obtained. The output is divided into two parts by a dividing circuit 27 and the two parts are sent to a differential amplifier 32 through BPFs 28 and 29 and detecting circuits 30 and 31. Then a detect signal of the level difference between the two parts is inputted in a sample holding circuit 34 through a polarity switching circuit 33 and a tracking control signal 39 is outputted.

CONSTITUTION:The multiplex CARS method which condenses the laser light (respective wave numbers are designated as omegap, omegas) of two kinds of different wavelengths to a point to be measured via a lens and matches omegap-omegas at the oscillation energy level difference of the nitrogen molecules so as to exist in the laser light condensed part is so operated by weaking the laser light intensity that the light energy density of the laser light condensed part attains <=2X10<10> watt/cm<2> lower than the conventional dielectric breaking strength of air. The lower limit of the intensity of the laser light having the lower intensity is preferably set at about 2X10<7>watt/cm<2>. The reason for such limitation lies in that noises are increased if the intensity is lower than said limit. The method for adjusting the intensity of the laser light includes a method for installing light attenuators to outlets of various dye laser beams 04 and 05.

Title: Catalyst for purification of exhaust gas
Inventor: MIYOSHI NAOTO
IPC: F01N3/08
Filed: 1994-02-23
Abstract: PURPOSE:To improve furthermore NOx purification rate by improving NOx absorbing power of an NOx absorbing material in a catalyst for purification of exhaust gas carrying the NOx absorbing material. CONSTITUTION:A noble metal 4 and an NOx absorbing material 5 carried by a porous layer 3 are uniformly dispersed and carried in the porous layer 3. As the noble metal and the NOx absorbing material are close to each other, NO in an exhaust gas is oxidized into NO2 by the noble metal when it is lean and it is absorbed simultaneously with the NOx absorbing material and the absorbed NO2 is reduced into HC and CO and purified by the action of the noble metal during stoichiometric time. Therefore, the NOx absorbing material absorbs NOx as much as possible.

Filed: 1992-01-17
Abstract: PURPOSE:To simply control electrification amount of a two-component developer and to inexpensively obtain a toner with stable electrification amount by producing the carrier under a specific condition by a plasma polymerization method. CONSTITUTION:Magnetic particles are placed on an electrode plate 2 of a plasma polymerization device, a fluorinated monomer is introduced into the device in plasma atmosphere and electric discharge is performed under the condition that the supply flow rate is 0.1-100cc/min, thus a fluorinated polymerized film is formed on a surface of the magnetic particle. In this way, an electrophotographic carrier in which a fluorinated polymerized film is extremely easily formed on the magnetic particle by using the plasma polymerization device, can be obtained. Accordingly, in the case of elecrophotographic carrier where only the electrification amount is not satisfied in the required quantity, even though various conditions such as a particle size and saturated magnetization are satisfied, the electrification amount can be simply controlled by coating the carrier with fluorinated film.

Abstract: PURPOSE:To accurately detect an antilock brake system (ABS) boundary line even when a vehicle passes through the boundary line at various designated speeds by shaping a boundary line passing signal detected with a sensor into a boundary detecting signal having a fixed width having no relation with the car speed of the vehicle by means of a one-shot multivibrator circuit. CONSTITUTION:A reflecting plate 8A is provided apart from a road surface 2 so that a boundary sensor 8b can be actuated when the center of the front axle of a vehicle to be tested is on the. boundary line 2a of the road surface 2. When the vehicle to be tested is run from a low-mu road to a high-mu road or from the high-mu road to the low-mu road, the plate 8a is faced to the sensor 8B within the beam width of the sensor 8B at the moment the front axle passes through the boundary line 2a and the sensor 8B outputs a trigger pulse-like boundary line passing signal to a one-shot multivibrator circuit 34 through a connector 17a. Since the circuit 34 uses the signal as a boundary detecting signal of a fixed width having no relation with the car speed of the vehicle after shaping the signal, the signal can be stably and surely recognized even when the vehicle is run at a high speed.
